Harry Burkitt – Give a Dam

Harry Burkitt, from community group ‘Give a Dam’ discussed the NSW Government’s
controversial plan to raise the height of the Warragamba dam. This is likely to have a significant impacts on threatened species in the Blue Mountains as well as potentially put the Blue
Mountains in danger of losing its UNESCO status.

Give a Dam has found some success by engaging corporate organisations such as insurance companies and super funds. In addition they continue to lobby the local politicians. He requested support (donations, letters to MP’s etc)  from OFF members as the campaign is expected to continue for +2 years. This very interesting talk was attended by 40 participants in the second OFF Zoom on-line meeting.  TAKE ACTION AT GIVE A DAM WEBSITE

 

Long Wall Mining in Sydney Water Catchment

On 27 April 2020  Aquatic Ecology Specialist Catherine Cunningham from Sydney Water shared her knowledge of long wall mining within Sydney’s water catchment areas and the potential impact on drinking water supply infrastructure.

This is very timely as the NSW Government has recently approved the extension of coal mining under the Woronora reservoir.

Australian climate and environment 10,000 years ago

Our March Meeting 2018  was well attended with 54 members & visitors. Our speaker this month was Richard Wright AM, Emeritus Professor of Anthropology, University of Sydney with the title of his talk being: “What was happening with the Australian climate and environment 10,000 years ago?”

In the 1970s and 1980s Richard conducted excavations on the edges of swamps in Victoria and NSW. These digs yielded insights into ancient archaeology, plants and mammals.

10,000 years ago at the start of the Holocene period was the beginning of a relatively stable climate and environment. Just prior to that, there had been an unusually large increase in temperatures.

Richard explained the contents of his excavations which were in deposits called loess. This term was new to most of the 54 members and guests at our meeting. These deposits consist of fine wind blown silt, typically in the 20–50 micrometre size range, twenty percent or less clay and the balance equal parts sand and silt that are loosely cemented by calcium carbonate. These deposits can be several metres in depth. Some very large examples can be found in China (more than 100 metres deep.)

Loess seem to be formed in Australia when lakes suddenly dry out causing these fine particles to be moved by the prevailing winds over short periods of time, resulting in homogeneous accumulations. Excavations by Richard unearthed examples of now extinct mega fauna.

Richard has also been involved in forensic excavations of mass graves in Bosnia for the United Nations and more recently in the recovery and identification of WW1 skeletal remains at Fromelles in France.

Eastern Water Dragon and their adaptability

We had a record number of attendees with 75 members and guests at our first general meeting in February
which featured speaker James Baxter -Gilbert. His enthusiastic talk on the Eastern Water Dragon and their adaptability to a changing urban environment was fascinating.
 
An interesting aspect of the presentation was the methodology applied by James and the rigorous testing used in his research.
 
He captivated the audience with his story on the elusive nature of the dragon – taking him 6 months to capture candidates. It is anticipated that his impressive research will be awarded a PhD in Science . James put the offspring of the originally captured and released lizards through all sorts of rigorous  experiments to test nature over nurture. The research looked at whether genetic difference was the reason the dragons have survived and thrived in a man – made world or if a steep curve of learned behaviour was the key .
 
In conclusion James believes it is a combination of both with final results ready in another month or so. After such grueling research and experimentation, the expectation of a PhD
is particularly satisfying. A touching end to the presentation was to see James’ Dad throw his arm around his son in a show of admiration and pride

Sheldon Forest Track – OFF Field day

OFF Field Day on Tuesday 15 August will be on Sheldon Forest Track, a 5-6 km walk from Turramurra Station through tall forest bordering Avon Creek and returning along Pymble streets.  This is not a long walk but includes steep streets and an uneven track with many stone steps descending to a running stream and back up again.  The track passes through majestic forest which transitions from Sydney Blue Gum through Blackbutt to Turpentine and thence Coachwood.  The main attractions are the changing vegetation, birdlife and peacefulness – it will be an opportunity for photography and ‘forest bathing’, so a leisurely pace is recommended.

Travel in 2nd last carriage departing Oatley Station at 8.45 am; 9.27 am train from Town Hall arriving Turramurra at 10.04 am.

Bring something for a late morning tea/early lunch along the track.  Back at Turramurra Station by about 2 pm.  Leader: Liz Cameron 9580 6621; elsmere02@gmail.com

Holding Back the Concrete – Dorothy Luther

HOLDING BACK THE CONCRETE – URBAN BUSH PROJECTS
DOROTHY LUTHER – OATLEY RSL 26 MAY AT 7:30PM

Inner Sydney is fast becoming a concrete jungle, with high rise apartments & shopping centres driving out the houses & corner shops that formed local communities. Even the remaining houses are being gentrified, with high walls hiding buxus hedges & garden furniture. Trees and gardens are disappearing because they’re untidy & take too much work.

But some intrepid souls are fighting back – a small but determined army of bush carers, community groups & feral gardeners are trying to stem the tide, with support from local governments – also under threat. They’re creating bush pockets, rain gardens, walking & cycle tracks that enable us to still keep in touch with nature & watch the antics of birds & lizards.
This is the story of some of those groups.

BIO
Dorothy Luther says she has been a member of APSoc for about 20 years, since buying an inner suburban house that needed a bush garden. She has been through the struggles of indigenous vs what will grow and has killed many plants in the process. This has led to many discussions with community gardening groups in the area. She is currently investigating rain forest plants since they seem to grow best in the much modified habitat. Her love of plants comes from growing up in the bush, not from any formal studies & botanical names are still confusing.
