Migratory Bird Season

A reminder that many of the birds that migrate to our area are arriving exhausted from having flown thousands of miles to be here. Please keep yourselves and your pets away from these shores during these months. They need their rest.

Baby Wildlife Season

Sydney Wildlife volunteer carers are reminding residents that it's baby season in the wildlife world. 
If you find a Joey on its own, it needs help. A sub-adult may be ok, but a Joey is not. If you find one, please try to contain it and keep it safe from predators and exposure and call either Sydney Wildlife (Sydney Metropolitan Wildlife Services) or WIRES. If you find a dead possum (ringtail or brushtail), check the pouch for a Joey. Brushtails generally have one but ringtails will have 2, sometimes three. If you are unable to, that’s ok, but please call it in to a wildlife organisation so someone can attend to it.

September is Koala Month & Biodiversity month

From Sydney Wildlife Mobile Care Unit

September is a very special month for wildlife:

1. Threatened Species Day
2. September is Biodiversity month
3. September is also Save Our Koalas month

• National Threatened Species Day is commemorated across the country on 7th September to raise awareness of plants and animals at risk of extinction. It is held each year to commemorate the anniversary of the death of the last remaining Tasmanian tiger (also known as the thylacine) at Hobart Zoo in 1936.

• The month of September is National Biodiversity Month every year and is held to help promote the importance of protecting, conserving and improving biodiversity.

• September is also Save the Koala month. So many koalas were killed in the 2020 bush fires but their plight is only intensifying with the further destruction of their habitat through over-development and logging.

We would like to thank all of those who do their bit to protect wildlife. Rescuers, carers, veterinarians, veterinary staff, journalists, editors, National Parks staff, our Police, Firies, trained rescue dogs and their trainers, educators, politicians, environment preservers and concerned members of the public.

And our long-suffering but ever-patient planet.

Our volunteer vets treat wildlife free of charge. If you appreciate our work please donate here: http://www.sydneywildlife.org.au/donate

Managing climate risks to assets and services: New South Wales Auditor-General's Report -  Performance Audit

Tuesday 7 September 2021 
This report assessed how effectively the Department of Planning, Industry and Environment (DPIE) and NSW Treasury have supported state agencies to manage climate risks to their assets and services.

Climate risks that can impact on state agencies' assets and services include flooding, bushfires, and extreme temperatures. Impacts can include damage to transport, communications and energy infrastructure, increases in hospital admissions, and making social housing or school buildings unsuitable.

NSW Treasury estimates these risks could have significant costs.

What we found
DPIE and NSW Treasury’s support to agencies to manage climate risks to their assets and services has been insufficient.

In 2021, key agencies with critical assets and services have not conducted climate risk assessments, and most lack adaptation plans.

DPIE has not delivered on the NSW Government commitment to develop a state-wide climate change adaptation action plan. This was to be complete in 2017.

There is also no adaptation strategy for the state. These have been released in all other Australian jurisdictions. The NSW Government’s draft strategic plan for its Climate Change Fund was also never finalised.

DPIE’s approach to developing climate projections is robust, but it hasn’t effectively educated agencies in how to use this information to assess climate risk.

NSW Treasury did not consistently apply dedicated resourcing to support agencies' climate risk management until late 2019.

In March 2021, DPIE and NSW Treasury released the Climate Risk Ready NSW Guide and Course. These are designed to improve support to agencies.

What we recommended
DPIE and NSW Treasury should, in partnership:
  • enhance the coordination of climate risk management across agencies
  • implement climate risk management across their clusters.
DPIE should:
  • update information and strengthen education to agencies, and monitor progress
  • review relevant land-use planning, development and building guidance
  • deliver a climate change adaptation action plan for the state.
NSW Treasury should:
  • strengthen climate risk-related guidance to agencies
  • coordinate guidance on resilience in infrastructure planning
  • review how climate risks have been assured in agencies’ asset management plans.

Smoke from the Black Summer fires created an algal bloom bigger than Australia in the Southern Ocean

In 2019 and 2020, bushfires razed more than 18 million hectares of land in Australia. For weeks, smoke choked major cities, leading to almost 450 deaths, and even circumnavigated the southern hemisphere.

As the aerosols billowed across the oceans many thousands of kilometres away from the fires, microscopic marine algae called phytoplankton had an unexpected windfall: they received a boost of iron.

Our research, published today in Nature, found this caused phytoplankton concentrations to double between New Zealand and South America, until the bloom area became bigger than Australia. And it lasted for four months.

This enormous, unprecedented algal bloom could have profound implications for carbon dioxide levels in the atmosphere and for the marine ecosystem. But so far, the impact is still unclear.

Meanwhile, in another paper published alongside ours in Nature today, researchers from The Netherlands found the amount of carbon dioxide emitted by the fires that summer was more than double previous estimates.

Absorbing 680 million tonnes of carbon dioxide

Iron fertilises phytoplankton and helps them grow, in the same way nutrients added in soil help vegetables grow. And like plants on land, phytoplankton photosynthesise — they absorb CO₂ as they grow and produce oxygen for fish and other marine creatures.

Bushfire smoke is an aerosol made up of many different chemicals, including iron. Shutterstock

We used satellite data to estimate that for phytoplankton to grow as much as they did in the Southern Ocean, they would have absorbed 680 million tonnes of CO₂. This means the phytoplankton absorbed roughly the same amount of CO₂ as released by the bushfires, according to the latest estimates released today.

The Dutch researchers found the bushfires released 715 million tonnes of CO₂ (or ranging 517–867 million tonnes) between November 2019 and January 2020. This surpasses Australia’s normal annual fire and fossil fuel emissions by 80%.

To put this into perspective, Australia’s anthropogenic CO₂ emissions in 2019 were much less, at 520 million tonnes.

Phytoplankton can have dramatic effects on climate

But that doesn’t mean the phytoplankton growth absorbed the bushfire’s CO₂ emissions permanently. Whether phytoplankton growth extracts and keeps CO₂ from the atmosphere depends on their fate.

If they sink to the deep ocean, then this represents a carbon sink for decades or even centuries — or even longer if phytoplankton are stored in ocean sediments.

But if they’re mostly eaten and decomposed near the ocean’s surface, then all that CO₂ they consumed comes straight back out, with no net effect on the carbon balance in the atmosphere.

In fact, phytoplankton have very likely played a role on millennial time scales in keeping atmospheric CO₂ concentrations down, and can affect the global climate in the long term.

For example, a 2014 study suggests iron-containing dust billowing over the Southern Ocean caused increased phytoplankton productivity, which contributed to reducing atmospheric CO₂ by about 100 parts per million. And this helped transition the planet to ice ages.

Phytoplankton blooms can also have a big impact on the marine ecosystem as they make excellent food for some marine creatures.

For example, more phytoplankton means more food for zooplankton that feed on phytoplankton, with effects up the food chain. It’s also worth noting this huge bloom occurred at a time of year when phytoplankton are usually in decline in this part of the ocean.

But whether there were any long-lasting effects from the bushfire-fuelled phytoplankton on the climate or ecosystem is unclear, because we still don’t know where they ended up.

Using revolutionary data

The link between fire aerosols and the increase in phytoplankton demonstrated in our study is particularly relevant given the intense fire activity around the globe.

Droughts and warming under global climate change are expected to increase the frequency and intensity of wildfires, and the impacts to land-based ecosystems, such as habitat loss and air pollution, will be dramatic. But as we now know, wildfires can also affect marine life thousands of kilometres away from land.

Previous models have predicted the iron-fertilising effect of bushfire aerosols, but this is the first time we’ve observed and demonstrated the connection at a large-scale.

Our study is mainly based on satellite data and observations from robotic floats that roam the oceans and collect data autonomously. These robotic floats are revolutionising our understanding of chemical cycling, oxygen variability and ocean acidification.

During the bushfire period, our smoke tracers reached concentrations at least 300% higher than what had ever been observed in the 22-year satellite record for the region.

Interestingly, you wouldn’t be able to observe the resulting phytoplankton growth in a true-colour satellite image. We instead used more sensitive ocean colour sensors on satellites to estimate phytoplankton concentrations.

So what’s next?

Of course, we need more research to determine the fate of the phytoplankton. But we also need more research to better predict when and where aerosol deposition (such as bushfire smoke) will boost phytoplankton growth.

For example, the Tasman Sea — between Australia and New Zealand — showed only mildly higher phytoplankton concentrations during the bushfire period, even though the smoke cloud was strongest there.

Was this because nutrients other than iron were lacking, or because there was less deposition? Or perhaps because the smoke didn’t stick around for as long?

Whatever the reason, it’s clear this is only the beginning of exciting new lines of research that link forests, wildfires, phytoplankton growth and Earth’s climate.

Rural Boundary Clearing Code opens up more bushland for destruction 

September 14, 2021
A new land-clearing code introduced by the NSW Government on Saturday could result in thousands of hectares of previously protected bushland being cleared on the spurious grounds of bushfire risk reduction. [1] 

“The new Rural Boundary Clearing Code could see thousands of hectares of wildlife habitat destroyed without requiring independent assessment of the environmental impacts,” Nature Conservation Council Chief Executive Chris Gambian said. 

“These codes do nothing practical to protect properties from catastrophic bushfires but they are guaranteed to increase deforestation and habitat fragmentation across large parts of the state.  

“Neither the NSW Bushfire Inquiry nor the Royal Commission recommend land clearing on property boundaries as a valid response to the Black Summer fires, but politicians in the government think they know better. Now we are stuck with a bad law that could do tremendous harm to the environment. 

“If these codes stand, it will be a black mark on the record of Matt Kean who in many respects has been a good minister for the environment. It would be shame if he were remembered for this rather than his more positive contributions.” 

NSW National Party MPs last year used the tragedy of the catastrophic 2019-20 bushfires to push their agenda of further weakening of land-clearing controls. 

They proposed letting landholders clear a 25m strip around their boundary even though none of the bushfires inquiries recommended such measures. 

Under the code, if neighbours took up their new rights, 50m-wide strips of clearing would occur across large parts of the state. 

The government passed the Bushfires Legislation Amendment Bill to enable the clearing last November but the devil was always going to be in the detail of the codes.  

Late last year, the Nature Conservation Council wrote to key ministers detailing minimum environmental standards any new code must meet, especially excluding areas of koala and other threatened species habitat. 

“The code could mean the difference between survival and extinction for koalas and other threatened species in some parts of the state, so it was vital that the government got this right,” Mr Gambian said.

Destroying vegetation along fences and roads could worsen our extinction crisis — yet the NSW government just allowed it

What do koalas, barking owls, greater gliders, southern rainbow skinks, native bees, and regent honeyeaters all have in common? Like many native species, they can all be found in vegetation along fences and roadsides outside formal conservation areas.

They may be relatively small, but these patches and strips conserve critical remnant habitat and have disproportionate conservation value worldwide. They represent the last vestiges of once-expansive tracts of woodland and forests, long lost to the chainsaw or plough.

And yet, the NSW government last week made it legal for rural landholders to clear vegetation within 25 metres of their property boundaries, without approval. This radical measure is proposed to protect people and properties from fires, despite the lack of such an explicit recommendation from federal and state-based inquiries into the devastating 2019-20 bushfires.

This is poor environmental policy that lacks apparent consideration or justification of its potentially substantial ecological costs. It also gravely undermines the NSW government’s recent announcement of a plan for “zero extinction” within the state’s national parks, as the success of protected reserves for conservation is greatly enhanced by connection with surrounding “off-reserve” habitat.

Small breaks in habitat can have big impacts

A 25m firebreak might sound innocuous, but when multiplied by the length of property boundaries in NSW, the scale of potential clearing and impacts is alarming, and could run into the hundreds of thousands of kilometres.

Some plants, animals and fungi live in these strips of vegetation permanently. Others use them to travel between larger habitat patches. And for migratory species, the vegetation provides crucial refuelling stops on long distance journeys.

For example, the roadside area in Victoria’s Strathbogie Ranges shown below is home to nine species of tree-dwelling native mammals: two species of brushtail possums, three species of gliders (including threatened greater gliders), common ringtail possums, koalas, brush-tailed phascogales, and agile antenchinus (small marsupials).

Roadside and fenceline vegetation is often the only substantial remnant vegetation remaining in agricultural landscapes. This section, in northeast Victoria’s Strathbogie Ranges, running north to south from the intersection, is home to high arboreal mammal diversity, including the threatened greater glider. Google Earth

Many of these species depend on tree hollows that can take a hundred years to form. If destroyed, they are effectively irreplaceable.

Creating breaks in largely continuous vegetation, or further fragmenting already disjointed vegetation, will not only directly destroy habitat, but can severely lower the quality of adjoining habitat.

This is because firebreaks of 25m (or 50m where neighbouring landholders both clear) could prevent the movement and dispersal of many plant and animal species, including critical pollinators such as native bees.

An entire suite of woodland birds, including the critically endangered regent honeyeater, are threatened because they depend on thin strips of vegetation communities that often occur inside fence-lines on private land.

For instance, scientific monitoring has shown five pairs of regent honeyeaters (50% of all birds located so far this season) are nesting or foraging within 25m of a single fence-line in the upper Hunter Valley. This highlights just how big an impact the loss of one small, private location could have on a species already on the brink of extinction.

But it’s not just regent honeyeaters. The management plan for the vulnerable glossy black cockatoo makes specific recommendation that vegetation corridors be maintained, as they’re essential for the cockatoos to travel between suitable large patches.

Native bee conservation also relies on the protection of remnant habitat adjoining fields. Continued removal of habitat on private land will hinder chances of conserving these species.

Disastrous clearing laws

The new clearing code does have some regulations in place, albeit meagre. For example, on the Rural Fire Service website, it says the code allows “clearing only in identified areas, such as areas which are zoned as Rural, and which are considered bush fire prone”. And according to the RFS boundary clearing tool landowners aren’t allowed to clear vegetation near watercourses (riparian vegetation).

Even before introducing this new code, NSW’s clearing laws were an environmental disaster. In 2019, The NSW Audit Office found:

clearing of native vegetation on rural land is not effectively regulated [and] action is rarely taken against landholders who unlawfully clear native vegetation.

The data back this up. In 2019, over 54,500 hectares were cleared in NSW. Of this, 74% was “unexplained”, which means the clearing was either lawful (but didn’t require state government approval), unlawful or not fully compliant with approvals.

Landholders need to show they’ve complied with clearing laws only after they’ve already cleared the land. But this is too late for wildlife, including plant species, many of which are threatened.

Landholders follow self-assessable codes, but problems with these policies have been identified time and time again — they cumulatively allow a huge amount of clearing, and compliance and enforcement are ineffective.

Vegetation along roadsides and close to fences can be critical habitat for greater gliders.

We also know, thanks to various case studies, the policy of “offsetting” environmental damage by improving biodiversity elsewhere doesn’t work.

So, could the federal environment and biodiversity protection law step in if habitat clearing gets out of hand? Probably not. The problem is these 25m strips are unlikely to be referred in the first place, or be considered a “significant impact” to trigger the federal law.

The code should be amended

Nobody disputes the need to keep people and their assets safe against the risks of fire. The code should be amended to ensure clearing is only permitted where a genuinely clear and measurable fire risk reduction is demonstrated.

Many native bees, like this blue-banded bee (Amegilla sp.), will use the nesting and foraging resources available in remnant vegetation patches. Michael Duncan

Granting permission to clear considerable amounts of native vegetation, hundreds if not thousands of metres away from homes and key infrastructure in large properties is hard to reconcile, and it seems that no attempt has been made to properly justify this legislation.

We should expect that a comprehensive assessment of the likely impacts of a significant change like this would inform public debate prior to decisions being made. But to our knowledge, no one has analysed, or at least revealed, how much land this rule change will affect, nor exactly what vegetation types and wildlife will likely be most affected.

A potentially devastating environmental precedent is being set, if other regions of Australia were to follow suit. The environment and Australians deserve better.

Zero Extinctions Target Set for NSW National Parks

Koalas, rock wallabies and the Nightcap Oak are some of the iconic species set to be protected under an historic National Parks plan to declare 221 sites as Assets of Intergenerational Significance (AIS) and set a target of zero extinctions of species on the NSW National Park estate.

Environment Minister Matt Kean said the National Parks and Wildlife Service (NPWS) Threatened Species Framework was about protecting and improving the health of our threatened and iconic species for future generations.

“Australia has the worst mammal extinction rate in the world and today in NSW, on Threatened Species Day, we say no more,” Mr Kean said.

“Globally, one million species face extinction over the coming decades and, as international biodiversity negotiations continue, everyone needs to aim high.” 

“Just as we have a net zero emissions target, we now also have a target of zero extinctions of species on our National Park estate, and are aiming to improve and stabilise the status of  threatened species.”

“But our plan isn’t just about targets – it’s also about action and that’s why I am making declarations for 221 sites to protect 92 endangered and iconic species,” Mr Kean said.

“These AIS declarations are a game changer for threatened species, triggering the strongest possible legal protections – mandating conservation plans, targeted feral animal control, bespoke fire management and monitoring and reporting.”

“We legislated the AIS provisions following the NSW Bushfire Inquiry, which highlighted the need to protect our most important ecological and cultural assets.”

The new AIS have been identified as home to species at risk from feral animals, bushfire and climate change, and follow the first AIS declaration earlier this year to protect the ancient Wollemi Pines.

An interactive map of all AIS sites HERE.

KEY FACTS
  • The AIS initiative is a key pillar of the National Parks Threatened Species Framework, which will align NPWS with the global biodiversity agenda and position the agency as a world leader in threatened species conservation.
  • AIS declarations for land containing important threatened species habitat, supported by Conservation Action Plans will ensure NPWS:
    • has identified the most important on-park habitat for threatened species, has up-to-date data on populations in these areas, and can share this information with others, including firefighting agencies and conservation partners
    • has action plans in place to reduce threats and improve the conservation status of threatened species in priority locations
    • is regularly monitoring the health of these populations and publicly reporting outcomes.
  • Other measures being implemented to protect threatened species on national parks include:
    • Acquisition of key threatened species habitat for addition to the national park estate
    • The establishment of a network of feral predator-free areas to support the return of more than 25 locally extinct species
    • Delivery of the largest feral animal control program in national park history
    • Establishment of a dedicated ecological risk unit to ensure threatened species are considered in new fire plans
    • Rolling out a world class ecological health framework across national parks
  • In total 66 plant species (Including the previously declared Wollemi Pine) and 27 animal species including 13 mammals, four birds, seven frogs and three reptiles
  • 221 AIS sites across 110 national parks totalling 301,843 hectares (3.89% of the National Parks estate
  • 92 new species of plants and animals to attain AIS status, including:
    • Brush-tailed Rock-wallaby:  7 sites including a highly endangered population in the Warrumbungles, where the population is now < 10 individuals
    • Koala: 15 of the most important koala strongholds on national parks such as Lake Innes, Port Macquarie and Upper Nepean SCA, south west of Sydney.
    • Dwarf Mountain Pine: Less than 800 plants remain in the spray zones along cliff faces between Wentworth Falls and Katoomba in the upper Blue Mountains. 
    • Nightcap Oak: a small population of around 125 adult plants found only on the Nightcap Range, north of Lismore

Ocean conservationists welcome Australia’s support for global plastics treaty

September 13, 2021
News that Australia has declared its support for a legally binding global plastics treaty has been welcomed by the nation’s leading ocean conservation organisation.

On Saturday, Federal Environment Minister, Sussan Ley, released a statement announcing Australia had endorsed a global ministerial statement and a new Pacific Regional Declaration on the Prevention of Marine Litter and Plastic Pollution and its Impacts.

The Pacific Declaration urges all United Nations Member States at the Fifth session of the United Nations Environment Assembly to support the establishment of a committee to negotiate a new binding global agreement covering the whole life cycle of plastics.

The Declaration calls for discussions on the agreement to consider the need for financial and technical support mechanisms to support plastic pollution reduction efforts across the globe, as well as consideration of financial assistance for Small Island Developing States in particular.

The Australian Marine Conservation Society (AMCS) stated that a global treaty on plastics is essential to truly stop plastic pollution at the source.

“With the equivalent of a dump truck’s worth of plastic entering the ocean every minute, and many plastics lasting for centuries in marine environments, we are on track to have more plastic than fish in the sea by 2050,” said Shane Cucow, Plastics Campaign Manager at AMCS.

“We welcome Australia’s leadership in supporting a legally binding global agreement, with meaningful global targets for reducing plastic pollution and funding to help all nations big and small face the crisis.

“While voluntary initiatives have been helpful, and some states have taken action such as banning single-use plastics, overall the action across the globe has been fragmented and slow.

“This is a global problem, and we are all responsible. It will require consistent and decisive action from all the nations of the world to clean up our oceans and save our wildlife from death by plastic.”

Mr Cucow said that while the declaration was welcome, Australia could go further and set an example for other nations.

“We urge the Australian government to show the world their commitment to a binding, effective global plastics treaty by co-sponsoring the draft resolution to begin negotiations in February 2022.”

What is the 'global plastics treaty'?

On Saturday 11 September 2021, the Federal Environment Minister, Sussan Ley announced that Australia had joined calls for a binding global plastics agreement.

Through a new Pacific Regional Declaration on the Prevention of Marine Litter and Plastic Pollution and its Impacts, Australia has joined pacific nations in urging United Nations Member States to negotiate a global agreement that is binding and that covers the whole life cycle of plastics, not just the plastic that ends up in the oceans.

Like a Paris Agreement for plastic, a new global treaty on plastic could be a game changer, with more than 100 countries around the world announcing their support for the idea.

But what does a UN treaty on plastic pollution mean for our oceans and wildlife, and what will it achieve? 

Plastic pollution is out of control
Our oceans are filling up with plastic. If current trends continue, the amount of plastic waste polluting the oceans will triple by the year 2040, growing to 29m tonnes a year – the equivalent of 50kg for every metre of coastline in the world.¹

International law on plastic pollution is vague and inconsistent. Without clear global rules and targets, multinational companies have been able to get away with producing unrecyclable plastics that are impossible to recover. Instead they end up in our oceans, threatening wildlife like turtles, whales and seabirds who die when they eat or get entangled in plastic.

Unless rapid and ambitious action is taken across the world, this problem will continue to escalate until there is more plastic than fish in the sea. 

Why do we need a global plastics treaty?
While voluntary initiatives have been helpful, and some states have taken action to ban single-use plastics or clean up plastics in local areas, action across the globe has been fragmented and ineffective.

  • There is no clear global ambition or target
  • No common obligation for nations to develop action plans
  • No agreed standards for monitoring and reporting of plastics discharge into the sea
  • No standardised review of the effectiveness of different pollution reduction measures
  • No specialised scientific body with a mandate to assess the global problem and give guidance to decision makers
There is no one international law on plastic pollution. We need a UN treaty on plastic pollution to eliminate plastic pollution in our oceans and to create a safe circular economy for plastics where all plastics are recovered for reuse, recycling or composting. 

What could a UN treaty on plastic pollution deliver?
While negotiations haven’t started yet, conservation experts across the globe have been working together to deliver a framework for action that would be strong and effective at fighting plastic pollution.

Some of the critical things a global agreement on plastic pollution could deliver include:
  • Global targets with deadlines for reducing plastic and cleaning up our oceans, with all nations working together to eliminate unnecessary or dangerous plastics and ensure all plastic is reused, recycled or composted in practice. This could include things like an international ban on dumping plastic in rivers and waterways, and global bans on plastics like bags and straws that are a high risk for ocean wildlife.
  • Monitoring and reporting on plastics in the natural environment, with nations required to report on their efforts to cut plastic. Advocates are also calling for a specialised international scientific body with a mandate to investigate and track the scale and sources of plastic pollution, providing world class scientific knowledge for effective policy making.
  • Financial and technical support, with a dedicated global body providing financial support and technical expertise for countries with limited capacity. This would be critical for helping badly affected nations at the edges of the worst plastic hotspots like the Great Pacific Garbage patch, many of whom lack the infrastructure and resources to deal with the waves of plastic washing up on their shores. 

What will it take to make a global plastics treaty happen?
We are at a critical point in this process, with a draft resolution that would formally start negotiations to be voted on at the UN Environment Assembly meeting in February 2022 (UNEA-5.2).

Ocean conservationists are calling on Australia to be a leader in efforts to secure a binding global treaty by co-sponsoring the draft resolution. This would send a strong message that Australia recognises the problems and wants to lead on finding the solutions. As ocean lovers, Australians expect no less.

Catch Alert drumlines set to be trialled on Queensland beaches will reduce marine wildlife deaths conservationists say

September 14, 2021
Queensland has announced that it will trial Catch Alert drumlines on four beaches starting this month.

Conservation groups Humane Society International (HSI) and the Australian Marine Conservation Society (AMCS) welcome the announcement, which follows the release of data last month that revealed 139 marine animals were caught in Queensland’s shark culling equipment during June and July, including one dolphin every 11 days and a turtle every five days.

The Catch Alert drumlines will be trialled at Mullambin Beach, Tanby Point, Fishermans Beach and Emu Park Beach on the Capricorn Coast until mid-2022. Designed to alert contractors when an animal is hooked, Catch Alert drumlines allow for animals, whether a shark or otherwise, to be released alive. Presently, Queensland’s traditional drumlines are checked only 260 days a year.

Large tiger, white, and bull sharks caught on the Catch Alert drumlines will be tagged and taken a distance offshore before they are released. Small sharks will be tagged and released on-site, while all other marine animals such as dolphins, turtles, and rays will be released immediately on-site. The ability to rapidly respond to animals caught on the drumlines will reduce the suffering of wildlife and greatly increase chances of survival.

The Catch Alert drumline trial comes more than three years after Humane Society International won a court case that questioned the legality of the lethal shark culling program operated in the Great Barrier Reef Marine Park. The legal action resulted in the Administrative Appeals Tribunal ordering lethal shark control be ended in the Great Barrier Reef as soon as reasonably possible, and that non-lethal swimmer protection be implemented instead. The Tribunal found ‘overwhelming evidence’ that culling sharks did not improve swimmer safety.

The best way to reduce the risk of shark bite is through a suite of modern alternatives such as Catch Alert or SMART drumlines, drone surveillance, personal shark deterrents and education. Archaic culling methods using nets and traditional drumlines are not able to reduce the risk and serve as nothing more than a false sense of security.

Lawrence Chlebeck, marine biologist for Humane Society International, said: “Culling shark populations does not keep swimmers safe and needlessly kills marine wildlife. Humane Society International says the trial will build confidence in modern non-lethal solutions so we can consign culling to history. There are better ways to protect both human lives and marine wildlife.”

Tooni Mahto, Campaign Manager for the Australian Marine Conservation Society, said: “We are pleased to see the Queensland government move forward with a more modern approach to keeping humans and marine wildlife safe in this trial. The sooner they can transition fully to a non lethal safety strategy, the better for everyone and everything in our oceans.”

HSI and AMCS are currently running a joint initiative to end the use of lethal shark control methods in Queensland in favour of more effective non-lethal technologies. Please visit www.sharkchampions.org.au for more information.

Western Sydney breathes a little easier thanks to waste incinerator decisions 

September 10, 2021
Western Sydney residents can breathe a little easier today after the NSW Government ruled out plans to establish two waste-to-energy power stations, at Eastern Creek and Blacktown. 

“This is great news for the community that has fought so hard to stop this proposal going ahead,” Nature Conservation Council Chief Executive Chris Gambian said. 

“Waste-to-energy incinerators should not be built in densely populated areas like Western Sydney where air quality frequently dips below healthy standards. 

“The region already carries a significant health burden from poor air quality and that is set to worsen when Western Sydney Airport opens. 

“The last thing the people of this region needed was two waste incinerators. 

“We applauded Environment Minister Matt Kean and Deputy Premier John Barilaro for bowing to public pressure and common sense. 

“We have to do much more to eliminate material from the waste stream by ramping up recycling and not sending it to landfills or incinerators.  

“At the moment, only a fraction of all plastics are recycled, so there is a lot we can do in that regard.” 

The government has identified West Lithgow Precinct, Parkes Special Activation Precinct, Richmond Valley Regional Jobs Precinct and Southern Goulburn-Mulwaree Precinct as priority locations to host waste-to-energy power stations. 

“Sydney should not merely export its environmental problems to the regions,” Mr Gambian said. 

“We believe that incineration is environmentally harmful and unsustainable. But if the government is going to proceed this way, these facilities must conform to world’s best practice,” Mr Gambian said. 

“Sydney should not merely export its environmental problems to the regions.  

“That means whatever facilities are built in the regions must operate to the highest environmental standards to ensure harmful chemicals and by-products are eliminated as much as possible during incineration.” 

Bylong Valley spared from coal mining again 

September 14, 2021
Bylong Valley has again been spared destruction by coal mining. The valley’s salvation this time was delivered by the NSW Court of Appeal, which this morning rejected KEPCO’s appeal against an earlier refusal. [1] 

The Korean mining giant had bought prime farmland in Bylong Valley near Mudgee in the state’s Central West and planned to construct a 6.5 million-tonnes-a-year coal mine. 

When the Independent Planning Commission rejected the plan in 2019, citing climate impacts among the grounds for its refusal, the company appealed to the Land and Environment. 

That court upheld the IPC decision but KEPCO appealed again [2], this time the Court of Appeal, which handed down its decision this morning.  

“Congratulations to Bylong Valley Protection Alliance, who have fought doggedly for years to save their beautiful region, and to the Environmental Defenders Office for so ably representing their client,” Nature Conservation Council Chris Gambian said.  

“Today’s decision should be the end of years of uncertainty for local landholders and communities who have fought a David-and-Goliath struggle to save their way of life and their beautiful valley.  

“It is a great victory for the people and comes off the back of the Southern Highlands community defeating the Hume coal project just a few weeks ago. 

“It is baffling that government resources are still being wasted on assessment of fossil fuel projects like these when the best scientific advice clearly against it.   

“We cannot afford to let the fossil fuel industry open any new mines or gas fields if we are to have a hope of keeping global temperatures within safe levels.”

NSW Government urged to give Bylong back to farmers following KEPCO’s latest legal loss

September 14, 2021
Bylong Valley locals and Lock the Gate Alliance say the NSW Berejiklian Government must facilitate the buy back of land KEPCO wanted to turn into a coal mine, after the company suffered yet another embarrassing defeat before the courts.

This morning, the South Korean corporation lost a second legal appeal over the Independent Planning Commission’s 2019 decision to reject its planned coal mine due to the impact it would have had on water, highly productive farming country, and the climate.

The loss comes as pressure from South Korea increases on KEPCO to abandon the ill-conceived  proposal, and after the Korea National Assembly Budget Office (NSBO) revealed farming groups had proposed purchasing the land owned by KEPCO.

The NSBO also revealed KEPCO had so far lost USD $405M in its pursuit to mine the fertile valley, and in January 2020 KEPCO's board marked down the value of its Bylong mining rights from $AUD642 million to zero in a report to the South Korean stock exchange.

Bylong Valley Protection Alliance spokesperson Phillip Kennedy said the NSW Government must act now to secure the land for farming families, so Bylong could once again be home to a thriving community.

“KEPCO’s foolish foray into Bylong has driven farmers and their families out. There is no one operating the local store any more - the valley is a shell of its former self," he said.

“This is the reality of what happens when a coal mining company tries to come to town.

“Despite all this, there is still a community here. We want the Berejiklian Government to extinguish the coal licence, just like it did with Shenhua on the Liverpool Plains, so Bylong can once again be the prosperous town it used to be.”

Lock the Gate Alliance spokesperson Nic Clyde said the NSW Government needed to intervene to break a stalemate where farming interests were unable to buy back farmland from a company that was unable to develop a coal mine.

“If the NSW Government offered modest compensation to KEPCO in exchange for cancellation of their coal lease, then our understanding is that farmers would look after the rest,” he said.

“There is pressure from South Korea on KEPCO to sell its Bylong Valley properties before the corporation loses any more money.

“The NSW Government must take advantage of this. John Barilaro needs to do what he did with Shenhua, extinguish KEPCO’s coal licence, and permanently rule out coal mining in the Bylong Valley food bowl.

“As the Independent Planning Commission found, this agricultural powerhouse is simply too important to be sacrificed for a coal mine.”

KEPCO was ordered to pay all costs.

NT 'Environment' Minister Lawler signals approval of fracking plan

September 13, 2021
The Protect Country Alliance is flabbergasted NT Environment Minister Eva Lawler has taken the unprecedented step of “partially” approving Empire Energy’s Environment Management Plan for its controversial seven well frack project near Borroloola.

Despite having been approved on September 3, the partial EMP approval was only quietly uploaded to the department’s website late last week. 

The approval also comes hot on the heels of increasing speculation the Gunner Government will backflip on its promise to fully offset all greenhouse gas emissions from fracking in the Beetaloo.

The section of the EMP that has been approved primarily deals with construction of roads and well pads and land clearing, and contains conditions related to the population of endangered Gouldian Finches in the area.

But Protect Country Alliance spokesperson Graeme Sawyer said the approval ignored the likely presence of many other endangered species, such as the nationally listed endangered Gulf Snapping Turtle.

“The approval completely ignores a range of new information from the Strategic Regional Environmental and Baseline Assessment (SREBA) Preliminary research showing endangered species and completely new species to science in the area

“The entire purpose of the SREBA was to research what species may be present in this little explored part of the Territory - this hasn’t happened - so there’s no telling what undiscovered and endangered animals may disappear thanks to this fracking project before we even know they're present.

“The Gunner Government is ignoring science just to push through an unwanted fracking project that puts groundwater, communities, and the environment at risk."

Mr Sawyer, who recently captured footage of Gouldian Finches for a David Attenborough documentary, said he had no confidence the conditions would protect the finch’s population.

“The Gouldian really is one of the most iconic bird species of the Top End, and with the stroke of a pen, Minister Lawler has put this fragile finch in further danger,” he said.

“The population of this finch is only just starting to recover in this area - a brand new fracking project that will bulldoze native vegetation for wellpads, pipelines, and new roads is going to send this population backwards.

“The EMP approvals focus on protecting breeding locations of the finch, but doesn’t give enough consideration to how the general clearing of habitat for roads, wellpads, and other infrastructure will place the finch under further pressure.”

Mr Sawyer said the partial approval of the EMP was effectively a full approval by stealth.

“Lawler has approved well pads, but not the wells. This is a sneaky way of letting fracking companies push ahead before fully assessing the impacts and risks of drilling and fracking several gas wells.

“Last week Federal Resources Minister Keith Pitt said the $21 million donation of public money to Empire would go ahead despite an ongoing legal challenge against the project.

“Then, lo and behold, we find out the NT Environment Minister has approved the construction of well pads.

“Let’s be clear - the NT Gunner Government and Morrison Federal Government are hand in hand working to steam roll this dodgy and polluting project through as quickly as possible.

“If they’re ultimately successful, it’s our underground water, communities, and iconic native species like the Gouldian and the Gulf Snapping Turtle that will pay the price.

“It is essential that the SREBA research is completed and properly considered before any further approvals are given.”

Consultation opens for mining exploration program

September 15, 2021
The Minister for Resources and Water Keith Pitt released today a consultation paper on the impact of the Junior Minerals Exploration Incentive, which is playing an important role in uncovering new resources deposits across Australia.

Responses to the consultation paper will inform an Annual Impact Assessment that measures the impact the JMEI scheme has had on exploration activities of participating companies. 

Minister Pitt said that the consultation process was an opportunity for companies to provide their views on the impact of the JMEI on their ability to raise finance.

“The Junior Minerals Exploration Incentive encourages new investment in small minerals exploration companies to help them make the discoveries needed to lock in the long-term future of Australia’s resources sector,” Minister Pitt said.

“The consultation paper released today gives interested parties the opportunity to express their views on the impact that the Junior Minerals Exploration Incentive is having on these vitally important businesses.”

The paper will look specifically at the program’s 2018-19 round as data is now available to assess the program’s impacts in this period.

As part of Budget 2021, the Australian Government announced the JMEI would be extended for a further four years. Release of the consultation paper follows the recent allocation of credits under the first round of the renewed JMEI by the Australian Tax Office. 

“We are already delivering on the commitment we made through Budget 2021 to extend support to junior explorers and it’s great to see that these businesses are doing their part by taking up the scheme,” Minister Pitt said. 

“The first round of the renewed program has seen $25 million in credits allocated to 34 companies, with interest far exceeding available support. 

“The resources and energy sector continues to be the backbone of our economy and is expected to deliver a record $334 billion in exports in 2021-22. The government wants to make sure the industry can continue to make a significant economic contribution for the benefit of all Australians and this hinges on new discoveries.”

The consultation paper is available on the department’s website. Submissions close on 27 October 2021.

Public consultation opens for greenhouse gas storage areas

September 14, 2021
Public consultation on five potential areas for the 2021 Offshore Greenhouse Gas Storage Acreage Release opened today. Minister for Resources and Water Keith Pitt said the acreage release provides opportunities for companies to explore for sites which have the potential for permanent geological storage of CO2 in offshore Australia.  

“This acreage release comes at a time when the oil and gas industry is looking for pathways to reduce their carbon emissions,” Minister Pitt said. 

“Carbon capture and storage is a priority low-emission technology for reducing the emissions of Australia’s resources sector. 

“The 2021 Offshore Greenhouse Gas Storage Acreage Release will play an integral role in supporting Australia’s resources sector to maintain Australia’s position as an energy export leader, whilst supporting global emission reductions”.   
  
Minister Pitt said that consultation will inform a decision to release an area for bidding. Submissions will also assist potential explorers understand factors they may need to consider when applying for an area or when planning exploration activities.

The government welcomes feedback from stakeholders on how they might be affected by exploration activities in an area. All interested parties are encouraged to provide comments and feedback on the nominated locations,” Minister Pitt said.

Industry have nominated the following areas for consideration in the 2021 GHG acreage release:
  • Bonaparte Basin
  • Browse Basin
  • Northern Carnarvon Basin.
Submission can be made via the Consultation Hub until October 12th 2021.

Minister Pitt states Coal to continue help powering Australian economy

September 9, 2021
Minister for Resources and Water Keith Pitt says Australian coal will not be staying in the ground while it continues to provide thousands of jobs and bring significant economic benefits both here and across the world.

Minister Pitt said coal remains Australia’s second largest export and that won’t be changing any time soon despite suggestions otherwise from London-based academics.

“The reality is that global demand for Australian coal is increasing and forecast to continue rising into the next decade at least,” Minister Pitt said.

“Australia accounts for approximately 8 per cent of the world’s thermal and metallurgical coal production, which is exported to over 25 countries including the UK, Germany and New Zealand.

“Our coal is providing the power and steel-making capability to developed and developing nations throughout Asia, creating economic and social opportunities for millions of people,” Minister Pitt said.

“That translates to around $50 billion in exports and the industry provides direct jobs for over 50,000 Australians and supports the jobs of another 300,000.

“Over $3 billion in royalties last financial year made a significant contribution to the New South Wales and Queensland Governments’ ability to pay for the health services, schools and other essential services Australians rely on.

“With coal prices currently now back at near record highs, the royalties and taxes paid by the industry will make an even more important contribution to the national economy as our recovery from the global COVID pandemic continues.

“Coal-fired power still provides around 65 per cent of Australia’s electricity and remains the most reliable form of power generation.

“Australia has shown that emissions reductions are possible alongside maintaining our critically important resources sector. Emissions have fallen by well over 20 per cent since 2005, above countries like the US, Canada and New Zealand and at the same time our resources exports have grown from $79 billion in 2005 to around $310 billion today.

“As our Government has repeatedly stated, technology holds the key to future emissions reductions, including carbon capture and storage which can contribute to a reduction in coal-fired power station emissions by 90 per cent or more, according to a 2020 International Energy Agency report.

“The hard-working men and women of the Australian coal industry can be assured they have the long-term support of this Government. Will Anthony Albanese and Labor offer the same commitment?”

Pitt states will continue funding for fracking despite court challenge to fracked gas cash splash

September 8, 2021
Protect Country Alliance has slammed Resources Minister Keith Pitt’s decision to order his department to keep handing millions of taxpayer dollars to fracking companies under the “Beetaloo Cooperative Drilling Program”, despite an ongoing Federal Court case against the scheme.

The scheme is being challenged in the Federal Court by the Environment Centre Northern Territory on the grounds Mr Pitt failed to make reasonable inquiries into a range of matters before giving $21 million to Liberal Party-linked fracking company Empire Energy.

Fracking companies have since lodged four other applications for funding from the $50 million tax payer funded scheme.


Protect Country Alliance spokesperson Graeme Sawyer said it was utterly arrogant for Mr Pitt to order his department to proceed dolling out millions in taxpayer funds to fracking companies in light of the court case and Senate Inquiry.

“Keith Pitt is being fairly challenged in the Federal Court - he should await the findings of the case before continuing to give public money to fracking companies. Instead he has spat the dummy and is refusing to allow justice to run its course fairly.

“NT Environment Minister Eva Lawler has not even finished assessing the Environment Management Plan for Empire Energy’s fracking project, yet Keith Pitt thinks this company should get $21 million from the taxpayer. 

“It is unethical for the Federal Minister to put pressure on the NT Environment Minister while she is considering the EMP for this particular group of frack wells. This raises further questions about the process that was followed when this grant was awarded. 

“Clearly there are major problems here - Territorians must be able to expect their best interests are being looked after, and that taxpayer money is being used wisely.

“His actions make a mockery of this nation’s legal system, NT environment regulations, and the distribution of the hard earned tax dollars of the Australian public.”

Beetaloo Cooperative Drilling Program will continue 

September 7, 2021: Media Release - The Hon Keith Pitt MP, Minister for Resources and Water
Minister for Resources and Water Keith Pitt has notified the Environment Centre of the Northern Territory that he intends to continue to operate the Beetaloo Cooperative Drilling Program. 

The Environment Centre of the Northern Territory lodged an application to the Federal Court on 28 July 2021 to have the drilling program and associated grant decisions set aside. The matter is currently progressing through Federal Court processes.

Minister Pitt said the Beetaloo Cooperative Drilling Program is a key measure under the Beetaloo Strategic Basin Plan and is crucial to the Government’s Gas Fired Recovery agenda. 

Minister Pitt said “I have requested my Department to proceed with the grant to Imperial Oil and Gas that I announced on 7 July 2021”. 

“It is important that we continue to get on with the job. This project, along with other activity in the Beetaloo Basin, has the potential to create over 6,000 jobs and make a significant contribution to secure Australia’s affordable and reliable energy supplies.

“I have also instructed my department to continue with the assessment of other applications to the Beetaloo Cooperative Drilling Program.”

Tasmania’s salmon industry detonates underwater bombs to scare away seals – but at what cost?

Benjamin J. Richardson, University of Tasmania

Australians consume a lot of salmon – much of it farmed in Tasmania. But as Richard Flanagan’s new book Toxic shows, concern about the industry’s environmental damage is growing.

With the industry set to double in size by 2030, one dubious industry practice should be intensely scrutinised – the use of so-called “cracker bombs” or seal bombs.

The A$1 billion industry uses the technique to deter seals and protect fish farming operations. Cracker bombs are underwater explosive devices that emit sharp, extremely loud noise impulses. Combined, Tasmania’s three major salmon farm operators have detonated at least 77,000 crackers since 2018.

The industry says the deterrent is necessary, but international research shows the devices pose a significant threat to some marine life. Unless the salmon industry is more strictly controlled, native species will likely be killed or injured as the industry expands.

Protecting a lucrative industry

Marine farming has been growing rapidly in Tasmania since the 1990s, and Atlantic salmon is Tasmania’s most lucrative fishery‑related industry. The salmon industry comprises three major producers: Huon Aquaculture, Tassal and Petuna.

These companies go to great effort to protect their operations from fur seals, which are protected in Australia with an exemption for the salmon industry.

Seals may attack fish pens in search of food and injure salmon farm divers, though known incidents of harm to divers are extremely rare.

The industry uses a number of seal deterrent devices, the use of which is approved by the government. They include:

  • lead-filled projectiles known as “beanbags”, which are fired from a gun

  • sedation darts fired from a gun

  • explosive charges or “crackers” thrown into the water which detonate under the surface.

In June this year, the ABC reported on government documents showing the three major salmon producers had detonated more than 77,000 crackers since 2018. The documents showed how various seal deterrent methods had led to maiming, death and seal injuries resulting in euthanasia. Blunt-force trauma was a factor in half the reported seal deaths.

A response to this article by the salmon industry can be found below. The industry has previoulsy defended the use of cracker bombs, saying it has a responsibility to protect workers. It says the increased use of seal-proof infrastructure means the use of seal deterrents is declining. If this is true, it’s not yet strongly reflected in the data.

Piercing the ocean silence

Given the prevalence of seal bomb use by the salmon industry, it’s worth reviewing the evidence on how they affect seals and other marine life.

A study on the use of the devices in California showed they can cause horrific injuries to seals. The damage includes trauma to bones, soft tissue burns and prolapsed eye balls, as well as death.

And research suggests damage to marine life extends far beyond seals. For example, the devices can disturb porpoises which rely on echolocation to find food, avoid predators and navigate the ocean. Porpoises emit clicks and squeaks – sound which travels through the water and bounces off objects. In 2018, a study found seal bombs could disturb harbour porpoises in California at least 64 kilometres from the detonation site.

There is also a body of research showing how similar types of industrial noise affect marine life. A study in South Africa in 2017 showed how during seismic surveys in search of oil or gas, which produce intense ocean noise, penguins raising chicks often avoided their preferred foraging areas. Whales and fish have also shown similar avoidance behaviour.

The study showed underwater blasts can also kill and injure seabirds such as penguins. And there may be implications from leaving penguin nests unattended and vulnerable to predators, and leaving chicks hungry longer.

Research also shows underwater explosions damage to fish. One study on caged fish reported profound trauma to their ears, including blistering, holes and other damage. Another study cited official reports of dead fish in the vicinity of seal bomb explosions.

Shining a light

Clearly, more scientific research is needed into how seal bombs affect marine life in the oceans off Tasmania. And regulators should impose far stricter limits on the salmon industry’s use of seal bombs – a call echoed by Tasmania’s Salmon Reform Alliance.

All this is unfolding as federal environment laws fail to protect Australian plant and animal species, including marine wildlife.

And the laws in Tasmania are far from perfect. In 2017, Tasmania’s Finfish Farming Environmental Regulation Act introduced opportunities for better oversight of commercial fisheries. However, as the Environmental Defenders Office (EDO) has noted, the director of Tasmania’s Environment Protection Authority can decide on license applications by salmon farms without the development necessarily undergoing a full environmental assessment.

Tasmania’s Marine Farming Planning Act covers salmon farm locations and leases. As the EDO has noted, the public is not notified of some key decisions under the law and has very limited public rights of appeal.

Two relevant public inquiries are underway – a federal inquiry into aquaculture expansion and a Tasmanian parliamentary probe into fin-fish sustainability. Both have heard evidence from community stakeholders, such as the Tasmanian Alliance for Marine Protection and the Tasmanian Conservation Trust, that the Tasmanian salmon industry lacks transparency and provides insufficient opportunities for public input into environmental governance.

The Tasmanian government has thrown its support behind rapid expansion of the salmon industry. But it’s essential that the industry is more tightly regulated, and far more accountable for any environmental damage it creates.


Read more: Why Indigenous knowledge should be an essential part of how we govern the world's oceans



In a statement in response to this article, the Tasmanian Salmonid Growers Association, which represents the three producers named above, said:

Around $500 million has been spent on innovative pens by the industry. These pens are designed to minimise risks to wildlife as well as to fish stocks and the employees. We believe that farms should be designed to minimise the threat of seals, but we also understand that non-lethal deterrents are a part of the measures approved by the government for the individual member companies to use. If these deterrents are used it is under strict guidelines, sparingly, and in emergency situations when staff are threatened by these animals, which can be very aggressive.

Tasmania has a strong, highly regulated, longstanding salmon industry of which we should all be proud. The salmon industry will continue its track record of operating at world’s best practice now and into future. Our local people have been working in regional communities for more than 30 years, to bring healthy, nutritious salmon to Australian dinner plates, through innovation and determination.The Conversation

How much will our oceans warm and cause sea levels to rise this century? We’ve just improved our estimate

Jakob Weis, University of Tasmania, Author provided
Kewei Lyu, CSIRO; John Church, UNSW, and Xuebin Zhang, CSIRO

Knowing how much sea levels are likely to rise during this century is vital to our understanding of future climate change, but previous estimates have generated wide ranges of uncertainty. In our research, published today in Nature Climate Change, we provide an improved estimate of how much our oceans are going to warm and its contribution to sea level rise, with the help of 15 years’ worth of measurements collected by a global array of autonomous underwater sampling floats.

Our analysis shows that without dramatic reductions in greenhouse gas emissions, by the end of this century the upper 2,000 metres of the ocean is likely to warm by 11-15 times the amount of warming observed during 2005-19. Water expands as it gets warmer, so this warming will cause sea levels to rise by 17-26 centimetres. This is about one-third of the total projected rise, alongside contributions from deep ocean warming, and melting of glaciers and polar ice sheets.

Ocean warming is a direct consequence of rising greenhouse gas concentrations in the atmosphere as a result of our burning of fossil fuels. This results in an imbalance between the energy arriving from the Sun, and the energy radiated out into space. About 90% of the excess heat energy in the climate system over the past 50 years is stored in the ocean, and only about 1% in the warming atmosphere.

Warming oceans cause sea levels to rise, both directly via heat expansion, and indirectly through melting of ice shelves. Warming oceans also affect marine ecosystems, for example through coral bleaching, and play a role in weather events such as the formation of tropical cyclones.

Systematic observations of ocean temperatures began in the 19th century, but it was only in the second half of the 20th century that enough observations were made to measure ocean heat content consistently around the globe.

Since the 1970s these observations indicate an increase in ocean heat content. But these measurements have significant uncertainties because the observations have been relatively sparse, particularly in the southern hemisphere and at depths below 700m.

To improve this situation, the Argo project has deployed a fleet of autonomous profiling floats to collect data from around the world. Since the early 2000s, they have measured temperatures in the upper 2,000m of the oceans, and sent the data via satellite to analysis centres around the world.

These data are of uniform high quality and cover the vast majority of the open oceans. As a result, we have been able to calculate a much better estimate of the amount of heat accumulating in the world’s oceans.

Global distribution of Argo floats. Argo project

The global ocean heat content continued to increase unabated during the temporary slowdown in global surface warming in the beginning of this century. This is because ocean warming is less affected than surface warming by natural yearly fluctuations in climate.

Current observations, future warming

To estimate future ocean warming, we need to take the Argo observations as a basis and then use climate models to project them into the future. But to do that, we need to know which models are in closest agreement with new, more accurate direct measurements of ocean heat provided by the Argo data.

The latest climate models, used in last month’s landmark report by the Intergovernmental Panel on Climate Change, all show ocean warming over the period of available Argo observations, and they project that warming will continue in the future, albeit with a wide range of uncertainties.

Ocean warming magnitudes from latest climate model simulations and Argo observations.

Read more: Explainer: what is climate sensitivity?


By comparing the Argo temperature data for 2005-19 with the simulations generated by models for that period, we used a statistical approach called “emergent constraint” to reduce uncertainties in model future projections, based on information about the ocean warming we know has already occurred. These constrained projections then provided an improved estimate of how much heat energy will accumulate in the oceans by the end of the century.

By 2081–2100, under a scenario in which global greenhouse emissions continue on their current high trajectory, we found the upper 2,000m of the ocean is likely to warm by 11-15 times the amount of warming observed during 2005-19. This corresponds to 17–26cm of sea level rise from ocean thermal expansion.

Climate models can also make predictions based on a range of different future greenhouse gas emissions. Strong emissions reductions, consistent with bringing surface global warming to within about 2℃ of pre-industrial temperatures, would reduce the projected warming in the upper 2,000m of the ocean by about half — that is, between five and nine times the ocean warming already seen in 2005-19.

This would equate to 8-14cm of sea level rise due to thermal expansion. Of course, reducing emissions so as to hit the more ambitious Paris target of 1.5℃ surface warming would reduce these impacts even further.

Other factors linked to sea levels

There are several other factors that will also drive up sea levels, besides the heat influx into the upper oceans investigated by our research. There is also warming of the deep ocean below 2,000m, which is still under-sampled in the current observing system, as well as the effects of melting from glaciers and polar ice sheets.

This indicates that even with strong policy action to reduce greenhouse gas emissions, the oceans will continue to warm and sea levels will continue to rise well after surface warming is stabilised, but at a much reduced rate, making it easier to adapt to the remaining changes. Cutting greenhouse gas emissions earlier rather than later will be more effective at slowing ocean warming and sea level rise.


Read more: If we stopped emitting greenhouse gases right now, would we stop climate change?


Our improved projection is founded on a network of ocean observations that are far more extensive and reliable than anything available before. Sustaining the ocean observing system into the future, and extending it to the deep ocean and to areas not covered by the present Argo program, will allow us to make more reliable climate projections in the future.The Conversation

‘Bloody fool!’: why Ripper the musk duck, and many other talkative Aussie birds, are exciting biologists

Anastasia Dalziell, University of Wollongong and Justin A. Welbergen, Western Sydney University

Recently, two native Australian birds have stolen the limelight with their impressive vocal imitations.

A superb lyrebird called Echo at Sydney’s Taronga Zoo has produced a painfully realistic vocal rendition of a human baby crying. Lyrebirds are already world-famous for their astonishingly accurate vocal mimicry, but these new recordings show their abilities can still surprise.

Then a new paper announced the arrival of an unexpected newcomer to Australia’s vocal imitation scene. A male musk duck (Biziura lobata) named Ripper was recorded imitating two stereotypical Australian sounds: a loudly shutting gate and a person exclaiming “you bloody fool!”.

The gate sound, at least, proved a hit with one of Ripper’s male colleagues who also ended up mimicking the sound. Excitingly, these recordings — originally from the 1980s and dug out from archives — provide the first material evidence of any duck species copying a sound in its environment, disrupting current understandings of the evolution of vocal learning in birds.

So what’s the big fuss about crying and swearing birds?

Why musk ducks are odd

Vocal production learning is a highly specialised trait that’s rare among animals. It requires flexible and sophisticated control over vocal production, and can be associated with enlarged regions of the brain relative to non-vocal learners.

For a long time, the only other animals known to possess similar vocal learning abilities to humans were parrots and male songbirds. But today, the musk duck joins a broad, but relatively small, list of non-human animals capable of vocal learning, including some bats, elephants, dolphins, whales and seals. Belatedly, we can now add female songbirds to the list of vocal production learners.

The loquacious “Ripper” was a captive-reared male musk duck at the Tidbinbilla Nature Reserve near Canberra. When he hatched, with the help of a foster bantam hen, he was the only musk duck there.

But even in the wild, musk ducks are odd. Male musk ducks are up to three times larger than females and have a distinctive bulbous lobe of skin hanging from their bills. Their name comes from the musky smell emitted by dominant males.

In the breeding season, males group together (in “leks”) and perform an exciting aquatic courtship displays for females, performing both day and night. Each male performs a structured, audio-visual display with his tail over his back, inflating his throat lobe, and splashing water while whistling loudly.

In the wild, male display whistles seem to form local dialects — a signature of vocal learning. But this doesn’t involve imitations of other species.

Ripper produced many elements of wild display, but would avidly display to people. His bizarre mimicry of anthropogenic sounds formed part of this display.

Listen to Ripper say ‘you bloody fool’

Mimicking in captivity

The story of Ripper is part of a long scientific tradition. Captive-reared parrots and some songbirds mimicking human speech feature in ancient European writings, including the works of Aristotle and Pliny the Elder.

More recently, the possible complexities of parrot communication were explored in a pioneering study of “Alex”, the captive African grey parrot, who had a vocabulary of more than 100 words.

Alex video caption.

By and large, such accounts of human imitations involve a captive individual raised in isolation from others of its own kind, but in close association with a human caretaker. The human caretaker then becomes the social model for the captive bird’s vocal development.

So while these examples reveal an animal’s capacity for vocal production learning, they don’t show that wild animals imitate sounds from their environment. Indeed, very few of the animal species that mimic people in captivity produce anything other than their own, species-specific vocalisations in the wild.

However, this is not true of Australia’s lyrebirds and other avian vocal mimics.

Mimicry in wild Australia

Two lyrebird species are famous for the diversity and accuracy of their vocal mimicry: the superb lyrebird of the wet eucalypt forests of southeast Australia, and the Albert’s lyrebird of Australia’s subtropical east.

In captivity, male superb lyrebirds have been recorded mimicking anthropogenic sounds ranging from chainsaws, emergency vehicle sirens to this new recording of a crying human baby.

In the wild, both males and females are proficient mimics of the vocalisations and wingbeats of other bird species — and occasionally mammals. A single individual male superb lyrebird can even mimic a flock of alarm-calling birds.

Despite many rumours, it remains a bit of a mystery when and how often wild lyrebirds mimic sounds of human origin.

Lyrebirds aren’t the only ones. Australia is the lucky home to a surprisingly large number of songbird species that regularly mimic in the wild, from tiny thornbills to the large enigmatic bowerbirds that, even in the wild, occasionally produce startlingly accurate renditions of humans.

But not all mimics are what they seem. In a heartbreaking example, the mimetic song of the Regent honeyeater is both a consequence and a cause of the species’ decline. Wild males copy other species because there aren’t enough males left to pass on their song to the next generation.

Threatened archival treasures

Ripper the swearing musk duck, Echo the bawling lyrebird, and the forgotten songs of the Regent honeyeater show us how much we still have to discover about Australia’s extraordinary birds. Far from being the biogeographical oddity, Australian birds are still destabilising biological theory.

Ripper was a bird of the 80s, and we only know of his bizarre mimicry because Rippers’ recordist, Dr Peter Fullagar, was on a mission to establish a natural history sound archive for Australia. Like all good 80s singers, Ripper was recorded on cassette tape before Peter digitised it.

It’s only from historical archives that researchers could discover that original song of the Regent honeyeater was unique to the species and more elaborate than the songs of contemporary males. Simply listening to captive-reared birds or the dwindling singers in the wild is no longer enough to reveal the Regent honeyeater’s natural song: the baseline has shifted.

What other treasures lie gathering dust in forgotten sheds or library stacks? We must be quick, before those cassette tapes degrade too far to be heard.

We managed to toilet train cows (and they learned faster than a toddler). It could help combat climate change

Can we toilet train cattle? Would we want to?

The answer to both of these questions is yes — and doing so could help us address issues of water contamination and climate change. Cattle urine is high in nitrogen, and this contributes to a range of environmental problems.

When cows are kept mainly outdoors, as they are in New Zealand and Australia, the nitrogen from their urine breaks down in the soil. This produces two problematic substances: nitrate and nitrous oxide.

Nitrate from urine patches leaches into lakes, rivers and aquifers (underground pools of water contained by rock) where it pollutes the water and contributes to the excessive growth of weeds and algae.

Nitrous oxide is a long-lasting greenhouse gas which is 300 times more potent than carbon dioxide. It accounts for about 12% of New Zealand’s greenhouse gas emissions, and much of this comes from the agricultural sector.

When cows are kept mainly in barns, as is the case in Europe and North America, another polluting gas — ammonia — is produced when the nitrogen from urine mixes with faeces on the barn floor.

However, if some of the urine produced by cattle could be captured and treated, the nitrogen it contains could be diverted, and the environmental impacts reduced. But how might urine capture be achieved?

We worked on this problem with collaborators from Germany’s Federal Research Institute for Animal Health and Research Institute for Farm Animal Biology. Our research is published today in the journal Current Biology. It forms part of our colleague Neele Dirksen’s PhD thesis.

Toilet training (but without the nappies)

In our research project, funded by the Volkswagen Foundation, we applied principles from behavioural psychology to train young cattle to urinate in a particular place — that is, to use the “toilet”

Behavioural psychology tells us a behaviour is likely to be repeated if followed by a reward, or “reinforcer”. That’s how we train a dog to come when called.

So if we want to encourage a particular behaviour, such as urinating in a particular place, we should reinforce that behaviour. For our project we applied this idea in much the same way as for toilet training children, using a procedure called “backward chaining”.

First, the calves were confined to the toilet area, a latrine pen, and reinforced with a preferred treat when they urinated. This established the pen as an ideal place to urinate.

The calves were then placed in an alley outside the pen, and once again reinforced for entering the pen and urinating there. If urination began in the alley, it was discouraged by a mildly unpleasant spray of water.

After optimising the training, seven out of the eight calves we trained learned to urinate in the latrine pen — and they learned about as quickly as human children do.

The calves received only 15 days of training and the majority learned the full set of skills within 20 to 25 urinations, which is quicker than the toilet-training time for three- and four-year-old children.

This showed us two things that weren’t known before.

  1. cattle can learn to attend to their own urination reflex, because they moved to the pen when ready to use it
  2. cattle will learn to withhold urination until they’re in the right place, if they’re rewarded for doing so.

The next stages

Our research is a proof of concept. Cattle can be toilet trained, and without much difficulty. But scaling up the method for practical application in agriculture involves two further challenges, which will be the focus in the next stage of our project.

First, we need a way both to detect urination in the latrine pen and deliver reinforcement automatically — without human intervention.

Calf exits through a gate.

This is probably no more than a technical problem. An electronic sensor for urination wouldn’t be difficult to develop, and small amounts of attractive rewards could be provided in the pen.

Apart from this, we’ll also need to determine the optimal location and number of latrine pens needed. This is a particularly challenging issue in countries such as New Zealand, where cattle spend most of their time in open paddocks rather than barns.

Part of our future research will require understanding how far cattle are willing to walk to use a pen. And more needs to be done to understand how to best use this technique with animals in both indoor and outdoor farming contexts.

What we do know is that nitrogen from cattle urine contributes to both water pollution and climate change, and these effects can be reduced by toilet training cattle.

The more urine we can capture, the less we’ll need to reduce cattle numbers to meet emissions targets — and the less we’ll have to compromise on the availability of milk, butter, cheese and meat from cattle.

Saving these family-focused lizards may mean moving them to new homes. But that’s not as simple as it sounds

Holly Bradley, Author provided
Holly Bradley, Curtin University; Bill Bateman, Curtin University, and Darryl Fogarty, Indigenous Knowledge

Am I not pretty enough? This article is part of The Conversation’s series introducing you to unloved Australian animals that need our help.


Spiny-tailed skinks (Egernia stokesii badia), known as meelyu in the local Badimia language in Western Australia, are highly social lizards that live together in family groups — an uncommon trait among reptiles.

They’re culturally significant to the Badimia people but habitat degradation and mining has put them under threat of extinction.

These sturdy, mottled lizards — which live in colonies in the logs of fallen trees and branches — are a candidate for what researchers call “mitigation translocation”.

That’s where wildlife are relocated away from high-risk areas (such as those cleared for urban development or mining) to lower risk areas.

It might sound simple. But research shows these mitigation translocation decisions are often made on an ad hoc basis, without a long-term strategic plan in place.

Not enough pre-planning or follow-up

There has been much research into assisted relocation of larger, charismatic mammals and birds. But other animals, such as reptiles with a less positive social image, have been less widely studied.

Our recent research has found there is often little pre-planning or follow-up to monitor success of mitigation translocations, even though reptile mitigation translocations do take place, sometimes on a large scale.

In fact, fewer than 25% of mitigation translocations worldwide actually result in long-term self-sustaining populations.

Mitigation translocation methods are also not being improved. Fewer than half of published mitigation translocation studies have explicitly compared or tested different management techniques.

Mitigation translocation studies also rarely consider long-term implications such as how relocated animals can impact the site to which they are moved — for example, if the ecosystem has limited capacity to support the relocated animals.

But it’s not just about ecosystem benefits. Preservation of species such as meelyu also has cultural benefits — but mitigation translocation can only be part of the solution if it’s done strategically.

The meelyu: a totem species

As part of Holly Bradley’s research into understanding how to protect meelyu from further loss in numbers, she had the privilege to meet with Badimia Indigenous elder, Darryl Fogarty, who identified meelyu as his family’s totem.

Totemic species can represent a person’s connection to their nation, clan or family group.

The meelyu or Western Spiny-tailed Skink is significant to the Badimia people and require translocation as part of mine site restoration and mitigation of population loss. Holly Bradley, Author provided

Unfortunately, Darryl Fogarty cannot remember the last time he saw the larger meelyu in the area. The introduction of European land management and feral species into Western Australia has upset the ecosystem balance — and this also has cultural consequences.

Preserving totemic fauna in their historic range can be a critical component of spiritual connection to the land for Indigenous groups in Australia.

In the past, this spiritual accountability for the stewardship of a totem has helped protect species over the long term, with this responsibility passed down between generations.

Before European colonisation, this traditional practice helped to preserve biodiversity and maintain an abundance of food supplies.

A strategic approach to future meelyu relocations from areas of active mining is crucial to prevent further population losses — for both ecological and cultural reasons.

Good mitigation translocation design

If we are to use mitigation translocation to shore up their numbers, we need effective strategies in place to boost the chance it will actually help the meelyu.

Good mitigation translocation design includes factors such as:

  • selecting a good site and understanding properly whether it can support new wildlife populations

  • having a good understanding of the animal’s ecological needs and how they fit with the environment to which they’re moving

  • using the right methods of release for the circumstances. For example, is it better to use a soft release method, where an individual animal is gradually acclimatised to its new environs over time? Or a hard release method, where the animal is simply set free in its new area?

  • having a good understanding of the cultural factors involved.

A holistic approach

A holistic approach to land management and restoration practice considers both cultural and ecological significance.

It supports the protection and return of healthy, functioning ecosystems — as well as community well-being and connection to nature.

Mitigation translocation could have a role to play in protection of culturally significant wildlife like the meelyu, but only when it’s well planned, holistic and part of a long term strategy.

Research reveals why pet owners keep their cats indoors – and it’s not to protect wildlife

Cat owners are urged to keep their pet indoors for a variety of reasons, including protecting wildlife and preventing the spread of disease. But our research has found an entirely different motivator for containing cats.

Concern for their cat’s safety is the primary reason people keep cats inside. And people who allow cats to roam are also motivated by concern for the animal’s well-being.

Keeping domestic cats properly contained is crucial to protecting wildlife. Cats are natural predators – even if they’re well fed. Research last year found each roaming pet cat kills 186 reptiles, birds and mammals per year.

If we want more domestic cats kept indoors, it’s important to understand what motivates cat owners. Our research suggests messages about protecting wildlife are, on their own, unlikely to change cat owners’ behaviour.

Cats are natural predators, and can kill many animals each year if left to roam. Shutterstock

Why keep your cat indoors?

Cat containment involves confining the animals to their owners’ premises at all times.

In the Australian Capital Territory, cat containment is mandatory in several areas. From July next year, all new cats must be contained across the territory, unless on a leash.

In Victoria, about half of local councils have some form of cat containment legislation. Current revisions to Domestic Animal Management Plans could mean the practice becomes more widespread.

Cats have long been part of human societies and play an important social role in their owners’ lives. But our affection for the animals means efforts to keep cats contained can be met with opposition.

Officials, conservation groups and others put forward a range of reasons for containing cats, including:

  • preventing cats from spreading diseases and parasites such as toxoplasmosis to both people and wildlife

  • reducing threats to wildlife, especially at night

  • reducing unwanted cat pregnancies

  • avoiding disputes with neighbours, including noise complaints, and cats defecating or spraying in garden beds and children’s sandpits

  • protecting cats from injury or death - such as being hit by a vehicle, attacked by dogs, snake bite and exposure to diseases and parasites.

So which argument is most persuasive? Our research suggests it’s the latter.

The Safe Cats Safe Wildlife campaign focuses on keeping cats safe. Zoos Victoria.

What we found

We surveyed 1,024 people in Victoria – 220 of whom were cat owners.

We found 53% of cat owners did not allow roaming. These people were more likely to hold concerns about risks to cats’ safety than cat owners who allowed roaming. They were also less likely to believe cats have a right to roam.

Some 17% of cat owners allowed their cats unrestricted access to the outdoors day and night, while 30% contained their cats at night but allowed some unrestricted outdoor access during the day.

Both cat owners and other respondents generally believed cat owners should manage their pet’s roaming behaviour. But for cat owners, concern about harm to wildlife was not a significant predictor of containment behaviour.

Instead, people who keep their cats contained were more likely to be worried that their cat might be lost, stolen, injured or killed.

It’s not that cat owners don’t care about native animals - only about one in ten cat owners said they’d never seriously considered how their cat affects wildlife. But our survey results show this isn’t a big motivation for keeping cats indoors.

What Victorian cat owners are doing, based on our survey findings. Author provided.

Roaming is dangerous

A roaming lifestyle can be risky to cats. A 2019 study of more than 5,300 Australian cat owners found 66% had lost a cat to a roaming incident such as a car accident or dog attack, or the cat simply going missing.

Despite the risks, people who let their cats roam are more likely to think the practice is better for the animal’s well-being – for example, that hunting is normal cat behaviour.

Owners who let their cat roam were more likely than those who contained their cat to believe their cat did not often hunt. While not all cats kill wildlife, those that do typically only bring home a small proportion of their catch. That means owners can be unaware of their cats’ impact.


Read more: Street life ain't easy for a stray cat, with most dying before they turn 1. So what's the best way to deal with them?


Cat owners must be made aware of the risks of roaming and equipped with the tools to keep their cats happy and safe at home. Unfortunately, research shows many Australian cat owners are not providing the safe environment and stimulation their cat needs when contained.

Cat containment doesn’t have to mean keeping the animal permanently in the house – nor does it require building them a Taj Mahal on the patio.

Cats can be outside while supervised or walked on leash. You can also cat-proof your backyard fence to keep them in.

Resources such as Safe Cat Safe Wildlife help owners meet their cat’s mental, physical and social needs while keeping them contained.

Moonee Valley City Council partners with the Safe Cats Safe Wildlife campaign to promote responsible cat ownership.

Changing containment behaviour

Our study shows cat containment campaigns can be more effective if messaging appeals to owners’ concern for their cats’ well-being. These messages could be delivered by trusted people such as vets.

Helping owners understand that cats’ needs can be met in containment, and giving them the tools to achieve this, may be the best way to protect wildlife.

Demonising cats is not the answer. The focus must shift to the benefits of containment for cats’ well-being if we hope to achieve a cat-safe and wildlife-safe future.

Climate change is coming for your snacks: why repeated drought threatens dried fruits and veggies

Shutterstock
Charith Rathnayaka, University of the Sunshine Coast

Potatoes can become more brittle, apples may be harder to dehydrate, and sultanas might be off the menu altogether — these are possible outcomes of recurring and intensifying droughts under climate change in Australia.

It might sound counter-intuitive, but drier conditions can affect the quality of fruit and vegetables at a cellular level, making them harder to process into dried foods. This has big implications for Australia’s food security and economy.

Dried foods account for a significant portion of our diet, and Australia exports around 70% of its produce, which is valued at close to A$49 billion per year. Dried produce make up an important part of this — for example, the export value of sultanas, currants and raisins alone in 2018-19 was $25.1 million.

If the taste, quality or availability of dried foods declines, we risk losing these lucrative markets. But my ongoing research on advanced drying methods aims to help overcome this challenge by carefully controlling how cells change their shape and structure.

Droughts are set to get worse

The most recent report by the Intergovernmental Panel on Climate Change (IPCC) warned Australia will become more arid as the world warms, bringing more droughts, drier soils, mass tree deaths and more.

The recent droughts across much of eastern Australia have already shown how climate change can wreak havoc on plant produce, as well as society and economy. For example, due to climate change impacts, agricultural profits fell by 23% over the period 2001-2020, or around $29,200 per farm, compared to historical averages.

Further, the COVID-19 pandemic has shown that uncertain environmental, social and economic conditions can lead to panic buying, highlighting the importance of food security and the stability of food supply.

It’s important to ensure our dried food supply is up to future stockpiling challenges, as chips and dried fruits are a staple of many diets in Australia. In 2019-2020, dried fruit such as sultanas, dried apple and apricots accounted for 12% of total fruit serves in the country.


Read more: Climate change has already hit Australia. Unless we act now, a hotter, drier and more dangerous future awaits, IPCC warns


How drought affects dried foods

Australian produce can be dried either in Australia or overseas, depending on the food type, manufacturer and the associated costs.

During the drying process, the cellular structure of fruit and vegetables go through significant changes. Cells and tissues can change their shape while shrinking into more compact forms.

If the drying process is not carefully controlled, it can lead to undesirable properties affecting the food’s taste and appearance, potentially reducing the market value and nutritional quality.

This is how drought makes things difficult. We know drought leads to water shortages in lakes and rivers, but research suggests it also dries out small plant cells and tissues.

If the absence of water in cells is ongoing — due to repeating droughts — the micro-properties of plants and their produce can change in the long term, whether the plants are grown in a large farm spanning hectares or in a small pot in your backyard.

Recurring droughts can make fruit and vegetables “fatigued” even before they’re harvested. This means the structure of the plant weakens with every drought, a bit like how bending a metal wire repeatedly eventually causes it to break.

For example, droughts can make plants, such as apples, more brittle and therefore un-processable. Droughts can also directly lead to smaller plants and respective harvests.

If the drought conditions are extreme, the moisture loss in the plants can be severe and the cells can naturally get damaged even without any further processing. In other words, if the recurring drought conditions are here to stay, dried foods such as potato chips, sultanas and dried apple as we know them could change for good.

With recurring droughts, potatoes can become brittle, making them harder to process. Shutterstock

Solving this problem with supercomputing

So, we know produce affected by drought is not as easy to process, often tastes different and is sometimes not usable at all. But what can we do about it?

Obviously, if climate change and subsequently recurring droughts could be avoided, the adverse effects on the dried food could also be dodged. First and foremost, global emissions must be rapidly and urgently cut.


Read more: Climate change means Australia may have to abandon much of its farming


But what if we can’t avoid it? In this case, we will need a sound Plan B.

One of the promising questions Australian researchers and engineers like me have asked is: can we modify the drying processes to match the changed properties of drought-affected produce? Doing so might enable the dried food processing industry to maintain the quality, taste, appearance and market value of its products.

But it won’t be easy. First, we need to correctly understand the exact nature of shape and size changes in plant cells, as affected by the lack of water. This is challenging, and requires computer simulations and supercomputing technologies.

With more research, we can prepare for the impact of drought on dried foods. Shutterstock

Through these simulations, it’s possible to estimate if the cells are going to be damaged when they go through the drying process. If we find there’ll be serious damage, the simulations can provide information on the ideal drying conditions. This means we can optimise the temperature, pressure, humidity and drying time to minimise the adverse effects.

This approach can lead to significant savings of time, money and energy while leading to increased quality and shelf life of dried food. With more research, extended computer modelling and simulations can lead to advanced drying on an industrial scale, leading to stronger food security and stability.

So, even if we will have to deal with more frequent and more intense droughts in the near future, the taste of your potato chips might be as good as ever, after all.

Avalon Golf Course bushcare needs you

We're so short of helpers we've had to cancel for the time being. Meanwhile the weeds will go gangbusters. 
We used to meet on the second Wednesday afternoon of each month. Could you come if we worked on another day or time? say a morning, or on a weekend day? 
Contact Geoff Searl on 0439 292 566 if you'd like to help. He'd love to hear from you. 

We have fun using the Tree Popper, here with our supervisor from Dragonfly Environmental. We can lever out quite big Ochnas, aka Mickey Mouse plant from Africa.  We want to bring back the bush, not let the weeds win!
   

Ochna or Mickey Mouse plant has yellow flowers in spring, then lots of green berries that turn black when ripe. Seedlings come up in hundreds. Ochna has a very strong taproot but the steady pressure of the Tree Popper lifts the plant out of the ground easily. The alternative control is repeated scraping and painting with Roundup, very slow and time consuming. If you have an Ochna you cant remove, you can enjoy the flowers, then PLEASE prune it so that berries can't develop.

New Shorebirds WingThing  For Youngsters Available To Download

A Shorebirds WingThing educational brochure for kids (A5) helps children learn about shorebirds, their life and journey. The 2021 revised brochure version was published in February 2021 and is available now. You can download a file copy here.

If you would like a free print copy of this brochure, please send a self-addressed envelope with A$1.10 postage (or larger if you would like it unfolded) affixed to: BirdLife Australia, Shorebird WingThing Request, 2-05Shorebird WingThing/60 Leicester St, Carlton VIC 3053.


Shorebird Identification Booklet

The Migratory Shorebird Program has just released the third edition of its hugely popular Shorebird Identification Booklet. The team has thoroughly revised and updated this pocket-sized companion for all shorebird counters and interested birders, with lots of useful information on our most common shorebirds, key identification features, sighting distribution maps and short articles on some of BirdLife’s shorebird activities. 

The booklet can be downloaded here in PDF file format: http://www.birdlife.org.au/documents/Shorebird_ID_Booklet_V3.pdf

Paper copies can be ordered as well, see http://www.birdlife.org.au/projects/shorebirds-2020/counter-resources for details.

Download BirdLife Australia's children’s education kit to help them learn more about our wading birdlife

Shorebirds are a group of wading birds that can be found feeding on swamps, tidal mudflats, estuaries, beaches and open country. For many people, shorebirds are just those brown birds feeding a long way out on the mud but they are actually a remarkably diverse collection of birds including stilts, sandpipers, snipe, curlews, godwits, plovers and oystercatchers. Each species is superbly adapted to suit its preferred habitat.  The Red-necked Stint is as small as a sparrow, with relatively short legs and bill that it pecks food from the surface of the mud with, whereas the Eastern Curlew is over two feet long with a exceptionally long legs and a massively curved beak that it thrusts deep down into the mud to pull out crabs, worms and other creatures hidden below the surface.

Some shorebirds are fairly drab in plumage, especially when they are visiting Australia in their non-breeding season, but when they migrate to their Arctic nesting grounds, they develop a vibrant flush of bright colours to attract a mate. We have 37 types of shorebirds that annually migrate to Australia on some of the most lengthy and arduous journeys in the animal kingdom, but there are also 18 shorebirds that call Australia home all year round.

What all our shorebirds have in common—be they large or small, seasoned traveller or homebody, brightly coloured or in muted tones—is that each species needs adequate safe areas where they can successfully feed and breed.

The National Shorebird Monitoring Program is managed and supported by BirdLife Australia. 

This project is supported by Glenelg Hopkins Catchment Management Authority and Hunter Local Land Services through funding from the Australian Government’s National Landcare Program. Funding from Helen Macpherson Smith Trust and Port Phillip Bay Fund is acknowledged. 

The National Shorebird Monitoring Program is made possible with the help of over 1,600 volunteers working in coastal and inland habitats all over Australia. 

The National Shorebird Monitoring program (started as the Shorebirds 2020 project initiated to re-invigorate monitoring around Australia) is raising awareness of how incredible shorebirds are, and actively engaging the community to participate in gathering information needed to conserve shorebirds. 

In the short term, the destruction of tidal ecosystems will need to be stopped, and our program is designed to strengthen the case for protecting these important habitats. 

In the long term, there will be a need to mitigate against the likely effects of climate change on a species that travels across the entire range of latitudes where impacts are likely. 

The identification and protection of critical areas for shorebirds will need to continue in order to guard against the potential threats associated with habitats in close proximity to nearly half the human population. 

Here in Australia, the place where these birds grow up and spend most of their lives, continued monitoring is necessary to inform the best management practice to maintain shorebird populations. 

BirdLife Australia believe that we can help secure a brighter future for these remarkable birds by educating stakeholders, gathering information on how and why shorebird populations are changing, and working to grow the community of people who care about shorebirds.

Aussie Bread Tags Collection Points

Collecting bread tags enables us to provide wheelchairs that change the life of disabled people in need, as well as keeping the tags out of landfill to help to preserve the environment. 

Bread Tags for Wheelchairs was started in South Africa in 2006 by Mary Honeybun. It is a community program where individuals and organisations collect bread tags, which are sold to recyclers. The money raised pays for wheelchairs for the less fortunate which are purchased through a local pharmacy. Currently about 500kg of bread tags are collected a month in South Africa, funding 2-3 wheelchairs.

We have been collecting bread tags nationally in Australia since September 2018 and now have more than 100 collection points across the country. In February 2019 we started local recycling through Transmutation - Reduce, Reuse and Recycle in Robe, SA, where our tags are recycled into products such as door knobs and bowls. Tags from some states are still sent to South Africa where a plastics company called Zibo recycles them into seedling trays.

These humble bits of polystyrene can make a real difference so get your friends, family, school, workplace and church involved. Ask school tuck shops and boarding school kitchens, child care centres, aged care facilities, hospitals, cafes and fast food outlets to collect for you - they get through a lot of bread!

All the information and signage for collecting or setting up a public collection point is on our website.

Report illegal dumping

NSW Government

The RIDonline website lets you report the types of waste being dumped and its GPS location. Photos of the waste can also be added to the report.

The Environment Protection Authority (EPA), councils and Regional Illegal Dumping (RID) squads will use this information to investigate and, if appropriate, issue a fine or clean-up notice. Penalties for illegal dumping can be up to $15,000 and potential jail time for anybody caught illegally dumping within five years of a prior illegal dumping conviction.

Wildlife Carers and Organisations in Pittwater:

Sydney Wildlife rescues, rehabilitates and releases sick, injured and orphaned native wildlife. From penguins, to possums and parrots, native wildlife of all descriptions passes through the caring hands of Sydney Wildlife rescuers and carers on a daily basis. We provide a genuine 24 hour, 7 day per week emergency advice, rescue and care service.

As well as caring for sick, injured and orphaned native wildlife, Sydney Wildlife is also involved in educating the community about native wildlife and its habitat. We provide educational talks to a wide range of groups and audiences including kindergartens, scouts, guides, a wide range of special interest groups and retirement villages. Talks are tailored to meet the needs and requirements of each group. 

Profile

Found an injured native animal? We're here to help.

Keep the animal contained, warm, quiet and undisturbed. Do not offer any food or water. Call Sydney Wildlife immediately on 9413 4300, or take the animal to your nearest vet. Generally there is no charge. Find out more at: www.sydneywildlife.org.au

Southern Cross Wildlife Care was launched over 6 years ago. It is the brainchild of Dr Howard Ralph, the founder and chief veterinarian. SCWC was established solely for the purpose of treating injured, sick and orphaned wildlife. No wild creature in need that passes through our doors is ever rejected. 

Profile

People can assist SCWC by volunteering their skills ie: veterinary; medical; experienced wildlife carers; fundraising; "IT" skills; media; admin; website etc. We are always having to address the issue of finances as we are a non commercial veterinary service for wildlife in need, who obviously don't have cheque books in their pouches. It is a constant concern and struggle of ours when we are pre-occupied with the care and treatment of the escalating amount of wildlife that we have to deal with. Just becoming a member of SCWC for $45 a year would be a great help. Regular monthly donations however small, would be a wonderful gift and we could plan ahead knowing that we had x amount of funds that we could count on. Our small team of volunteers are all unpaid even our amazing vet Howard, so all funds raised go directly towards our precious wildlife. SCWC is TAX DEDUCTIBLE.

About 33% (about 1600 ha excluding National Parks) of the original pre-European bushland in Pittwater remains in a reasonably natural or undisturbed condition. Of this, only about 400ha remains in public ownership. All remaining natural bushland is subject to encroachment, illegal clearing, weed invasion, feral animals, altered drainage, bushfire hazard reduction requirements and other edge effects. Within Pittwater 38 species of plants or animals are listed as endangered or threatened under the Threatened Species Act. There are two endangered populations (Koala and Squirrel Glider) and eight endangered ecological communities or types of bushland. To visit their site please click on logo above.
