Yellow Tail Black Cockatoo Research

P1000148 Citizen scientists are being asked to help in a joint project between University of New South Wales, Botanic Gardens & Centennial Parklands.

In recent years there have been significant decline in the populations of Yellow Tailed Black Cockatoos. Birds have been seen in urban areas feeding on introduced pines and food sources in bush parks and golf courses.

Pictures here were taken in July and August from a flock of nine seen on an Old Man Banksia (Banksia serrata) on Lloyd Street Oatley.

Clean-up Australia Day 2016

On Sunday 6th March, 40 people registered at Jinna Reserve South Peakhurst for the OFF Clean-up activity. Numbers from the Society were boosted by a contingent from Mortdale Girl Guides and their parents, plus some individuals who had seen our notices around the suburb.IMG_3194

Some OFF members took their canoes out onto Lime Kiln Bay to get access to what was lurking in
the mangroves, the rest picked their way around the muddy foreshores of the bay on both the
Peakhurst and Oatley Park side of the inlet.

IMG_3173Total rubbish collected was 36 bags, nearly half of it plastic bottles; also 9 car tyres, PVC piping and metal objects. This was an outstanding result,although real success should be measures by the absence of any rubbish in our bushland and waterways. We thank all those who gave up their morning to contribute to this community event.

Dollarbirds in Lime Kiln Bay

Dollarbird -Limekiln BayRecently, David Mercer of Georges River Wildlife photographed  some young dollarbirds leaving a tree hollow in Lime Kiln Bay on 24 January 2016 .

Dollarbirds are a summer migrant. They arrive in Australia in late spring, Sept/October and then mate and build a nest, typically in a tree hollow. They can have up to 4 young. The young leave the nest in mid summer, Dec to January.

The parents continue feeding them for some time before the young become independent.
The birds leave Australia in late summer, March to April, and fly north to Papua New Guinea and the Solomon Islands where they spend the winter.

While they are not a rare bird in Australia, they are not commonly seen in the Sydney area and it is a treat to have them nesting so close to suburbia. It is good reflection on the richness and good habitat that Lime Kiln Bay provides that these birds continue to use the area and successfully raise young.

Wetlands Day 2 February

 World Wetlands Day is celebrated internationally each year on 2 February. It marks the anniversary of the signing of the Convention on Wetlands of International Importance (Ramsar Convention) in Ramsar, Iran, on 2 February 1971.

World Wetlands Day was first celebrated in 1997. Since then government agencies, non-government organisations and community groups have celebrated World Wetlands Day by undertaking actions to raise public awareness of wetland values and benefits and promote the conservation and wise use of wetlands.  For more see Department of Environment

Drains are for Rain

The Leader 20 Jan 2016 Its clear drains are for rain so butt out
Oatley Flora and Fauna Conservation Society  is painting messages on drains in the Penshurst, Mortdale and Oatley area to remind people of what drains are for and what their misuse can do to wetlands and river systems. Their current target is the drain system that flows into the Lime Kiln Bay wetland.
 
Leader published the photos and LKB/ drain stencilling story in Wed 20 January 2016 edition..
It is on-line on The Leader website.  There is room on the website version for the public to make comments.

Lime Kiln Bay Guided Walks

IMG_1683OFF conducted free guided walks on 8 and 12 December around Lime Kiln Bay Wetland to show interested people how the wetlands improve the quality of storm water runoff and the abundant native plants and wildlife that the wetland supports.

The walks are part of  a  project undertaken by the society to raise awareness in the local community of potential environmental impacts on the wetland from urban activities. What goes down the drain ends up in the wetland and then into the Georges River. The project is being funded from the NSW Minister for the Environment’s Conservation Fund. It will benefit the local community and Council by improving the long-term health of local waterways and reducing maintenance costs of Council’s drainage infrastructure.

Perils of Plastic- Prof Banati visits Myles Dunphy Reserve

IMG_1674Our Stream Watch group were fortunate to have a on site visit from Professor Banati Leader of the ANSTO Plastics project.
The increased presence of certain degradable plastics, including biodegradable plastics, is a challenge for the recycling of plastics more generally since the various plastics can be difficult to sort. Contamination of the waste stream with similar appearing but non-recyclable material by many seen as the Achilles heel of recycling.  A significant portion of plastic waste ends up in our oceans.
 IMG_1667
Professor Banati said the team’s observations were changing perceptions about how the increased degradability of a material, such as plastic, may help to reduce the litter problem but, if not properly managed, might cause a contamination problem in the future.
Recent research shows that this is problematic due to the chemicals contained within plastics, as well as the pollutants that plastic attract once they are in the marine environment. For more see Guardian Dec 2014

 ANSTO contributes to this collaborative research effort by using nuclear technologies to measure minute quantities of material such as the contaminants potentially leaching or being absorbed by degrading plastic material. ANSTO has national and international collaborations current work is being undertaken with Monash University, UTAS and CSIRO.



IMG_1676Other Research

In a new study, published Dec 2014 by the journal Royal Society Open Science, a British scientist reports the riddle of the “missing” plastic as solved: It sits in deep waters, broken down into tiny fibers and embedded in the sediment of the most remote places on Earth.

The discovery of microplastic in such remote marine habitats raises new questions about the potential for plastic debris to contaminate the food chain. Scientists have already documented that fish, birds, turtles, and other marine animals eat plastic. Thompson and his team found an even greater accumulation of plastic than previously suspected. The more plastic there is, he says, the more potential for toxicity to marine life.

Mark Coure MP launches “Drains are Just for Rain”

Mark Coure 25 Nov (2)On 25 November, Mark Coure MP launched OFF storm water drain stencil project. The society plans to stencil 120 signs to raise awareness in the local community of potential environmental impacts on the Lime Kiln Bay wetland from urban activities. What goes down the drain ends up in the wetland and then into the Georges River.
