Pumice Washed Up On Our Beaches This Week + Turimetta Beach Erosion + Puffer Fish Washed Ashore - The World Where You Live!
The storms that began on Sunday, last weekend, have brought what is called 'pumice' onto our beaches by Wednesday.
Pumice is igneous rock with a foamy appearance. The name is derived from the Latin word "pumex" which means "foam". Throughout history pumice has been given many names because its formation was unclear. In former times it was called "Spuma Maris", meaning froth of the sea in Latin, because it was a frothy material thought to be hardened sea foam. It was also known as "écume de mer" in French and “Meerschaum” in German for the same reason. Around 80 B.C., it was called "lapis spongiae" in Latin for its vesicular properties. Many Greek scholars decided there were different sources of pumice, one of which was in the sea coral category.
Pumice, called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. It is typically light colored.
Pumice is created when super-heated, highly pressurised rock is violently ejected from a volcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurisation. The depressurisation creates bubbles by lowering the solubility of gases (including water and CO2) that are dissolved in the lava, causing the gases to rapidly exsolve (like the bubbles of CO2 that appear when a carbonated drink is opened). The simultaneous cooling and depressurisation freezes the bubbles in a matrix. Eruptions under water are rapidly cooled and the large volume of pumice created can be a shipping hazard for cargo ships. The pores of pumice and pumicite can have sizes from a wide range.
Pumice has been used in the medicinal industry for more than 2000 years. Ancient Chinese medicine used ground pumice along with ground mica and fossilised bones added to teas to calm the spirit. This tea was used to treat dizziness, nausea, insomnia, and anxiety disorders. Ingestion of these pulverised rocks were actually able to soften nodules and was later used with other herbal ingredients to treat gallbladder cancer and urinary difficulties. In western medicine, beginning in the early 18th century, pumice was ground into a sugar consistency and with other ingredients was used to treat ulcers mostly on the skin and cornea. Concoctions such as these were also used to help wounds scar in a healthier manner. In approximately 1680 it was noted by an English naturalist that pumice powder was used to promote sneezing.
Pumice has been used as a material in personal care for thousands of years. It is an abrasive material that can be used in powdered form or as a stone to remove unwanted hair or skin. In ancient Egypt skincare and beauty were very important to all classes and makeup and moisturisers were widely used. One common trend was to remove all hair on the body using creams, razors and pumice stones. Pumice in powdered form was used to whiten teeth in ancient Rome. Nail care was very important in ancient China; nails were kept groomed with pumice stones and to remove calluses. It was discovered in a Roman poem that pumice was used to remove dead skin as far back as 100 BC and likely before then. It has been used throughout many eras since then, including the Victorian Era.
Today, many of these techniques are still used; pumice is widely used as a skin exfoliant. Hair removal techniques have evolved over the centuries, however abrasive material like pumice stones are still used. "Pumice stones" are often used in beauty salons during the pedicure process to remove dry and excess skin from the bottom of the foot as well as calluses. Finely ground pumice has been added to some toothpastes as a polish, similar to Roman use, and easily removes dental plaque build up. Such toothpaste is too abrasive for daily use. Pumice is also added to heavy-duty hand cleaners (such as lava soap) as a mild abrasive. Old beauty techniques using pumice are still employed today but newer substitutes are easier to obtain.
One of the Pittwater Online regular contributors, Joe Mills, sent in some photos of beach erosion at Turimetta Beach and a Puffer fish this week too - they run below so you can see how these big waves bring so much debris on to our shores and also take big sections of same back out to sea - which they will eventually return to those same beaches.
Pufferfish are scaleless fish and usually have rough to spiky skin. All have four teeth that are fused together into a beak-like form. Diet. The diet of the pufferfish includes mostly invertebrates and algae. Large specimens will even crack open and eat clams, mussels, and shellfish with their hard beaks.

Northern Tableland's endangered wallabies bounding back after bushfire
July 27, 2020
Endangered Brush-tailed Rock-wallabies and their young have been spotted bounding through the bush in Oxley Wild Rivers and Guy Fawkes River National Parks, delighting NSW National Parks and Wildlife Service (NPWS) staff surveying the impact of the bushfires.
Piers Thomas, Senior Conservation Planning Officer with NPWS, said an aerial survey of 48 known colonies in Oxley Wild Rivers National Park found the iconic animal in more than 80% of the locations.
"All of the colonies surveyed had areas of burnt habitat, yet we spotted 90 surviving individuals," said Mr Thomas.
"This figure is consistent with counts taken in previous years so it is very reassuring.
"It's great to see that these endangered animals have not only survived the fires but are adapting to the changed landscape.
"Most of the colonies with surviving wallabies received emergency supplementary feeding of lucerne, sweet potato and carrots and they are most definitely bouncing back," said Mr Thomas.
Further ground-based surveys done after the fires also identified individual wallabies that were known to researchers from before the fire, including one that has been spotted over the last 11 years.
The surveys, conducted in June 2020, also revealed some young at foot that would have been in the pouch when the fire hit, and some new pouch young that may have been born since the event.
For the first time the aerial survey extended into nearby Guy Fawkes River National Park in the upper reaches of the Aberfoyle River.
"In more good news for the species we discovered an additional 25 Brush-tailed Rock-wallaby colonies in this park and saw surviving individuals in 12 of the previously-known sites," Mr Thomas said.
The 2019–20 fires burnt more than 80% of known Brush-tailed Rock-wallaby habitat in NSW.
Post-fire assessments carried out by NPWS and the NSW Government's Saving our Species program showed that local wallabies had been left stranded with limited food and water and the supplementary feeding was vital to help maintain these colonies and allow them to recover.
NPWS, Saving our Species and partners delivered more than 3 tonnes of supplementary feeding to reserves in the northern tablelands. In total, close to 12 tonnes of supplementary food has been delivered to Brush-tailed rock-wallabies across New South Wales.
Mount Kaputar’s famous pink slugs need your help! Send us your slug snapshots
July 28, 2020
They may be bright pink, but Mount Kaputar’s famous giant pink slugs sometimes give us the slip, so the National Parks and Wildlife Service is urging visitors to send in your slug snapshots on a new app.

National Parks and Wildlife Service (NPWS) Senior Project Officer Adam Fawcett said visitors to Mount Kaputar National Park can share in the slug search.
“The slugs are part of the Mount Kaputar Land Snail and Slug Threatened Ecological Community (TEC), a group of 20 snail and one slug species that exist nowhere else in the world.
“While the pink slugs have become the pin-ups of this TEC, the snails are also fascinating, with some being only as big as a pin head.
“Recently we conducted a search to see how the slugs and snails were faring after the summer bushfires.
“While we recorded good numbers of our snail species and could see evidence of recent slug activity with their distinctive feeding trails, the slugs did give our surveyors the slip.
“That’s why other tools like the Slug Sleuth App can be really helpful in helping us ensure the slug’s survival.
“By snapping shots of the slugs on the app, it’s hoped we can track the health and status of the ecological community across Mount Kaputar National Park.
“The information collected will help improve our knowledge of where the threatened ecological community occurs, its recovery post-fire, preferred habitat and assist with ongoing conservation efforts.
“The app was developed as part of the NSW Government’s Saving our Species program and is free to download for both iOS and Android devices. Use the search term 'Slug Sleuth' or 'Kaputar' to find the app in your preferred app store,” Mr Fawcett said.
The Saving our Species program is the NSW Government's commitment to securing the future of the State's threatened plants and animals. To find out more, or to get involved with Saving our Species visit Help save our threatened species.
Australia’s first Indigenous Chair for Biodiversity and Environmental Science
July 21, 2020
Curtin University has appointed noted Australian ecologist Dr Stephen van Leeuwen as Australia’s first Indigenous Chair for Biodiversity and Environmental Science.
Dr Stephen van Leeuwen
The Biodiversity Chair will be the first of its type in Australia and one of only a few globally that directly engage with First Nations Peoples. A key focus of the position will be building a Western-Indigenous science interface, so that landscapes for threatened species can be managed in new ways that are sympathetic to the maintained stewardship provided, over the last 65,000 years, by the Aboriginal people.
Curtin Vice-Chancellor Professor Deborah Terry said she is thrilled that a person of Professor van Leeuwen’s outstanding scientific and national profile has accepted the prestigious role.
“The appointment of Dr van Leeuwen is testament to his influential leadership in his field and will bring an Indigenous focus to the University in a way that will create healthy ecological and healthy cultural outcomes for Western Australia and the nation,” Professor Terry said.
“Professor van Leeuwen’s commitment to delivering innovative and enduring positive outcomes for biodiversity management through collaboration with both Traditional Owners and other land managers, made him an outstanding candidate for the role.
“We are also delighted that Dr van Leeuwen is returning to his university ‘home’, where he completed his PhD in 1997.”
The newly created role is part of the long-term partnership between Curtin University and BHP, which over the past decade has supported engineering and chemistry studies at the university including through funding for new facilities, and scholarships to help increase female, indigenous and regional student participation.
Dr van Leeuwen is a Noongar man with strong links to Country in the Busselton and Margaret River areas of south-west Western Australia.
He spent three decades as a senior scientist with the Western Australian Department of Biodiversity, Conservation and Attractions and is a leading botanical landscape ecologist.
As the inaugural Chair for Biodiversity and Environmental Science, Dr van Leeuwen’s key task will be to lead research programs promoting excellence and innovation in the fields of biodiversity and environmental science through collaborative networks within Indigenous communities, the broader academic community in Western Australia, Australia and internationally.
Limeburners Creek National Park, Goolawah National Park and Goolawah Regional Park: Public Consultation
Planning for the future –NSW National Parks and Wildlife Service is preparing a new plan of management for Limeburners Creek National Park, Goolawah National Park and Goolawah Regional Park.
These parks are in the traditional Country of the Dunghutti and Birpai Aboriginal Peoples. The parks play a fundamental role in the lives of local Aboriginal people, helping to maintain a tangible link to the past and enabling continued connections to Country.
The existing plan of management for Limeburners Creek National Park was written in 1998. The areas that are now Goolawah National Park and Goolawah Regional Park were formerly Goolawah State Park and Crown land. Initial community consultation about the Goolawah parks was undertaken in 2012, soon after they were transferred to National Parks and Wildlife Service.
Since this time large new areas have been added to the parks, including the intertidal zone on some of the beaches. There has also been a steady increase in visitors, and new recreational uses have become popular. Information about the values of the park has improved and new approaches to managing fire, pests and weeds have been developed.
Accommodating all of these visitors, maintaining the unique visitor experience and protecting the environment is challenging. Good planning is essential to manage increasing demand and provide sustainable visitor facilities and opportunities while minimising impacts and retaining the natural and low key nature of this beautiful stretch of coast. The development of a new combined plan of management will help to protect the parks' unique values and improve the effectiveness of how we manage the parks.
What opportunities will the community have to contribute to the development of a new plan of management?
Previous consultation, including a community forum, identified a range of issues important to the local community which will be considered in the new plan. It is now time to reach out and reconnect with our neighbours, stakeholders and local communities, as well as extending the invitation to the wider community of park users.
There are now 2 opportunities to be involved in the development of the plan of management for Goolawah Regional Park and Goolawah and Limeburners Creek national parks:
- During the development of the draft plan - register your interest below to receive updates and be notified of further consultation dates. Complete the form to provide your ideas on what you believe are the most important values of the parks and how they should be managed in the future. Your input will be used to draft a plan that reflects community values and aspirations.
- During public exhibition of the draft plan - there will be another opportunity to have your say when the draft plan of management is completed and put on public exhibition for 90 days. Anyone can submit comments on the draft plan during this time.
Register your interest
Complete the online form here to register your interest, provide initial input and be notified of further consultation dates. Tell us what is important to you about the parks and what you would like to see in the future. Comments close 30 October 2020.

Rat Poisons are killing our wildlife: Alternatives
BirdLife Australia is currently running a campaign highlighting the devastation being caused by poison to our wildlife. Rodentcides are an acknowledged but under-researched source of threat to many Aussie birds. If you missed BirdLife's rodenticide talk but would like to know more, share data and comment on the use of rodenticides in Australia please visit: https://www.actforbirds.org/ratpoison
Owls, kites and other birds of prey are dying from eating rats and mice that have ingested Second Generation rodent poisons. These household products – including Talon, Fast Action RatSak and The Big Cheese Fast Action brand rat and mice bait – have been banned from general public sale in the US, Canada and EU, but are available from supermarkets throughout Australia.
Australia is reviewing the use of these dangerous chemicals right now and you can make a submission to help get them off supermarket shelves and make sure only licenced operators can use them.
There are alternatives for household rodent control – find out more about the impacts of rat poison on our birds of prey and what you can do at the link above and by reading the information below.
Let’s get rat poison out of bird food chains.
The Australian Pesticides and Veterinary Medicines Authority (APVMA) – is currently asking Australians for their views on how rodent poisons are regulated.

Pesticides that are designed to control pests such as mice and rats cane also kill our wildlife through either primary or secondary poisoning. Insecticides include pesticides (substances used to kill insects), rodenticides (substances used to kill rodents, such as rat poison), molluscicides (substances used to kill molluscs, such as snail baits), and herbicides (substances used to kill weeds).
Primary poisoning occurs when an animal ingests a pesticide directly – for example, a brushtail possum or antechinus eating rat bait. Secondary poisoning occurs when an animal eats another animal that has itself ingested a pesticide – for example, a greater sooty owl eating a rate that has been poisoned or an antechinus that had eaten rat bait.
Rodenticides are the most common and harmful pesticides to Australian wildlife. Though no comprehensive monitoring of non-target exposure of rodenticides has been conducted, numerous studies have documented the harm rodenticides do to native animals. In 2018, an Australian study found that anticoagulant rodenticides in particular are implicated in non-target wildlife poisoning in Australia, and warned Australia’s usage patterns and lax regulations “may increase the risk of non-target poisoning”.
Most rodenticides work by disrupting the normal coagulation (blood clotting) process, and are classified as either “first generation” / “multiple dose” or “second generation” / “single dose”, depending on how many doses are required for the poison to be lethal.
These anticoagulant rodenticides cause victims of anticoagulant rodenticides to suffer greatly before dying, as they work by inhibiting Vitamin K in the body, therefore disrupting the normal coagulation process. This results in poisoned animals suffering from uncontrolled bleeding or haemorrhaging, either spontaneously or from cuts or scratches. In the case of internally haemorrhaging, which is difficult to spot, the only sign of poisoning is that the animal is weak, or (occasionally) bleeding from the nose or mouth. Affected wildlife are also more likely to crash into structures and vehicles, and be killed by predators.
An animal has to eat a first generation rodenticide (e.g. warfarin, pindone, chlorophaninone, diphacinone) more than once in order to obtain a lethal dose. For this reason, second generation rodenticides (e.g. difenacoum, brodifacoum, bromadiolone and difethialone) are the most commonly used rodenticides. Second generation rodenticides only require a single dose to be consumed in order to be lethal, yet kill the animal slowly, meaning the animal keeps coming back. This results in the animal consuming many times more poison than a single lethal dose over the multiple days it takes them to die, during which time they are easy but lethal prey to predators. This is why second generation poisons tend to be much more acutely toxic to non-target wildlife, as they are much more likely to bioaccumulate and biomagnify, and clear very slowly from the body.
Species most at risk from poisons
Small Mammals
Small mammals including possums and bandicoots often consume poisons such as snail bait, or rat bait that has been laid out to attract and kill rats, mice, and rabbits. Poisons such as pindone are often added to oats or carrots, and lead to a slow, painful death of internal bleeding. Australian possums often consume rat bait such as warfarin, which causes extensive internal bleeding, usually resulting in death.
There is a very poor chance of survival. Possums are also known to consume slug bait, which results in a prolonged painful death mainly from neurological effects. There is no treatment.
Small mammals can also be poisoned by insecticides. Possums, for example, can ingest these poisons when consuming fruit from a tree that has been sprayed with insecticide. Rescued by a WIRES carer, the brushtail possum joey pictured below was suffering from suspected insecticide poisoning. Though coughing up blood, luckily the joey did not ingest a lethal dose as he survived in care and was later released.
Large Mammals
Despite their size, large mammals including wallabies, kangaroos and wombats can also fall victim to pesticide poisoning. Wallabies and kangaroos have been known to suffer from rodenticide poisoning, while poisons often ingested by wombats include rat bait from farm sheds, and sodium fluroacetate (1080) laid out to kill pests such as cats and foxes.
Australian mammals are also impacted by the use of insecticides. DDT, although a banned substance, has been reported as killing marsupials.
Birds
Birds have a high metabolic rate and therefore succumb quickly to poisons. Australian birds of prey – owls (such as the southern boobook) and diurnal raptors (such as kestrels) – can be killed by internal bleeding when they eat rodents that have ingested rat bait. A 2018 Western Australian study determined that 73% of southern boobook owls found dead or were found to have anticoagulant rodenticides in their systems, and that raptors with larger home ranges and more mammal-based diets may be at a greater risk of anticoagulant rodenticide exposure.
Insectivorous birds will often eat insects sprayed with insecticides, and a few different species of birds may be affected at the same time. Unfortunately little can be done and death most often results.
Organophosphates are the most widely used insecticide in Australia. Birds are very susceptible to organophosphates, which are nerve toxins that damage the nervous system, with poisoning occurring through the skin, inhalation, and ingestion. Organophosphates can cause secondary poisoning in wild birds which ingest sprayed insects. Often various species of insectivorous birds are affected at the same time as they come down to eat the dying insects. After a bird is poisoned, death usually occurs rapidly. Raptors have also been deliberately or inadvertently poisoned when organophosphates have been applied to a carcass to poison crows.
Organochlorine pesticides (OCPs) are persistent, bio-accumulative pesticides that include DDT, dieldrin, heptachlor and chlordane. OPC’s have been used extensively in the agriculture industry since the 1940s. Some of the more common product names include Hortico Dieldrin Dust, Shell Dieldrex and Yates Garden Dust. Although no OCP’s are currently registered for use in the home environment in Australia, many of these products still remain in use on farms, in business premises and households. OCP poisons remain highly toxic in the environment for many years impacting on humans, animals, birds and especially aquatic life. They can have serious short-term and long-term impacts at low concentrations. In addition, non-lethal effects such as immune system and reproductive damage of some of these pesticides may also be significant. Birds are particularly sensitive to these pesticides, and there have even been occasions where the deliberate poisoning of birds has occurred. Tawny frogmouths are most often poisoned with OCP’s. The poisons are stored in fat deposits and gradually increase over time. At times of food scarcity, or during any stressful period, such as breeding season or any changes to their environment, the fat stores are metabolised, and with it, the poison load in their blood streams reaches acute levels, causing death.
Although herbicides, or weed killers, are designed to kill plants, some are toxic to birds. Common herbicide glyphosate (Roundup) will cause severe eye irritation in birds if they come into contact with the spray. Herbicides also have the impact of removing food plants that birds, or their insect food supply, rely on. Birds can also readily fall victim to snail baits, either via primary or secondary poisoning.
Reptiles and Amphibians
As vertebrate species, reptiles and amphibians are also at risk of pesticides. Though less is known about the effects of pesticides on reptiles and amphibians, these animals have been known to fall victim to pesticide poisoning. Blue-tongue lizards, for example, often consume rat bait and die of internal bleeding. A 2018 Australian study also found that reptiles may be important vectors (transporters) of rodenticides in Australia.
How to keep pests away and keep wildlife safe
Remember, pesticides are formulated to be tasty and alluring to the target species, but other species find them enticing, too. It is safest for wildlife, pets and people for us to not use any pesticides, and prevent or deter the presence of pests practically, rather than attempt to eliminate them chemically.
Tips to prevent and deter wildlife deaths from poisoning:
- Deter rats and mice around your property by simply cleaning up; removing rubbish, keeping animal feed well contained and indoors, picking up fallen fruits and vegetation, and using chicken feeders removes potential food sources.
- Seal up holes and in your walls and roof to reduce the amount of rodent-friendly habitat in your house.
- Replace palms with native trees; palm trees are a favourite hideout for black rats, while native trees provide ideal habitat for native predators like owls and hawks which help to control rodent populations.
- Set traps with care in a safe, covered spot, away from the reach of children, pets and wildlife. Two of the most effective yet safe baits are peanut butter and pumpkin seeds.
- To control slugs, terracotta or ceramic plant pots can be placed upside down in the garden or aviary. Slugs and snails will seek the dark, damp area this creates, and can be collected daily. They can then be drowned in a jar of soapy water. You can also sink a jar or dish into the soil and fill it with beer. The slugs are attracted to the yeast in the beer, fall in and then drown.
If turning to pesticides as a last resort:
- Use only animal-safe slug baits.
- Place tamper-proof bait stations out of reach of wildlife.
- Avoid using loose whether pellets or poison grain, present the highest risk, the latter being particularly attractive to seed-eating birds and to many small mammal species.
- Read the label and use as instructed.
- Avoid products containing second generation products difenacoum, brodifacoum, bromadiolone and difethialone, which are long-lasting and much more likely to unintentionally poison wildlife via secondary poisoning.
- Cover individual fruits when spraying fruit trees with insecticides.
Poisons kill dogs too
Because of their poisonous nature, pesticides pose a risk to animals and people alike, including pets and children. Roaming pets like cats and dogs are most at risk of being poisoned, with one 2016 study at the Norwegian University of Life Sciences finding that one in five dogs had rat poison in its body, and a 2011 study by the Humane Society in the United States finding that 74% of their pet poisoning cases are due to second-generation anticoagulants such as rat baits.
It is best to avoid the use of all pesticides, or otherwise use them sparingly, carefully and only after researching each poison and its correct usage. Always supervise pets and children, keep poisons locked out of their reach, and be vigilant in public spaces where pesticides may have accumulated, e.g. poisons can accumulate in streams or puddles where herbicides have recently been sprayed.
If you suspect your pet has been poisoned, seek veterinary help immediately.
If you suspect your child or another adult has been poisoned, do not induce vomiting and call the NSW Poisons Information Centre on 13 11 26 for 24/7 medical advice, Australia-wide.

Echidna Season
Echidna season has begun. As cooler days approach, our beautiful echidnas are more active during the days as they come out to forage for food and find a mate. This sadly results in a HIGH number of vehicle hits.
What to do if you find an Echidna on the road?
- Safely remove the Echidna off the road (providing its safe to do so).
- Call Sydney Wildlife or WIRES
- Search the surrounding area for a puggle (baby echidna). The impact from a vehicle incident can cause a puggle to roll long distances from mum, so please search for these babies, they can look like a pinky-grey clump of clay
What to do if you find an echidna in your yard?
- Leave the Echidna alone, remove the threat (usually a family pet) and let the Echidna move away in it's own time. It will move along when it doesn't feel threatened.
If you find an injured echidna or one in an undesirable location, please call Sydney Wildlife on 9413 4300 for advice.

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.

Avalon Community Garden
Community Gardens bring people together and enrich communities. They build a sense of place and shared connection.
Avalon Community Garden is a community led initiative to create accessible food gardens in public places throughout the Pittwater area. Our aim is to share skills and knowledge in creating fabulous local, organic food. But it's not just about great food. We also aim to foster community connection, stimulate creative ideas for community resilience and celebrate our abundance. Open to all ages and skills, our first garden is on the grounds of Barrenjoey High School (off
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.
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.
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.

Pittwater's Environmental Foundation
Pittwater Environmental Foundation was established in 2006 to conserve and enhance the natural environment of the Pittwater local government area through the application of tax deductible donations, gifts and bequests. The Directors were appointed by Pittwater Council.
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.
