Speakers and Topics for 2009

February 13th


Elizabeth Brown


Perambulations in New Caledonia and Vanuatu

March 13th


Keith Muir


Gardens of Stone National Park and Issues impacting on our parks


Keith Muir is the Executive Officer for the Colong Foundation for Wilderness who, as the name would suggest, is a major campaigner for the protection and management of remaining wilderness areas in NSW. Keith will be talking about proposed extensions to the Gardens of Stone National Park, near Lithgow, to extend over the sandstone landscapes of the Newnes Plateau, the broken stone country west of the Plateau and the Airly-Genowlan mesa to the north, in the Capertee Valley. The proposal also includes the Blue Mountains Western Escarpment lands from Blackheath into Lithgow. The proposal area is an absolutely spectacular place and the last unprotected part of Myles Dunphy’s 1934 Greater Blue Mountains Park vision. Keith will also discuss threats to this region such as the RTA proposal for the Bells Line Super-highway.

No meeting as it is Good Friday



May 8th


Deidrie Jinks


Lowland Rainforest

Background: Deidre is from the Sydney Rainforest Nursery, Ourimbah, and has a passion for rainforest. The nursery is unusual in that the focus is on local diversity, with many species being generally unavailable commercially. Propagation is from local sources to provide plants for revegetation and other environmental repair projects. Deidre is involved in the planning of riparian rehabilitation, bushland management and the development of property plans. She will talk about lowland rainforest in the Sydney region.

June 12th


Professor Andy Pitman


How do scientists know that humans are causing global warming?


Andy is a lead author in the IPCC and is Co-Director, Climate Change Research Centre, University of New South Wales. He is a climate modeller with a major focus on land surface processes. Some of Andy’s work involves investigations of carbon dynamics, including vegetation responses to increasing CO2 and how uncertain our projections of the future might be given instability in terrestrial carbon storage. Andy has interests in climate extremes and how these are likely to change in the future

For many people the competing claims, on one hand, that human-induced climate change is real with potentially catastrophic consequences for humanity, versus opposing claims that we are witnessing a natural event that has nothing to do with human actions, is extremely confusing. Professor Pitman will explain why many scientists believe that we are facing a global warming episode that is due to human activities and the evidence for this. You will also have the opportunity to pose questions about observations and processes that appear to contradict supposed global warming trends or humanity’s role in this.

July 10th


Dr Ross Peacock


Patterns of long-term recovery in vegetation following logging


Ross Peacock is a plant ecologist employed by the NSW Department of Environment and Climate Change, based at Macquarie University in the Department of Biological Sciences. Ross and his team of researchers have projects which include a study of the impacts of climate change on North Coast plant communities, the development of predictive models of the distribution of vegetation in north western NSW for the catchment authorities and the development of biodiversity monitoring systems for production forests in Tasmania.

Ross has worked for a wide range of forest management and nature conservation agencies in Tasmania, Victoria and NSW. For his PhD, Ross examined how vegetation in Tasmania responded to the application of different logging systems used on steep slopes, for example how cable logging differed from conventional ground based systems. He will describe the results of work he commenced in Victoria in the late 1980’s and Tasmania in the early 1990’s which examines how vegetation communities respond to logging disturbance, work which has continued using the original study sites. Ross will also overview work in progress describing how cool temperate rainforests logged in the 1940’s and 1950’s in northern NSW (and since incorporated into the reserve network) are recovering and potentially responding to the effects of global warming.


August 14th


Noel Rosten, Margaret Hamilton and Bill Jones.

Q & A Session:

Propagation and Growing of Native Plants on the North Shore

Background: These three members possess a wealth of knowledge on how to propagate and grow native plants in this area, so come along and put them through the ringer. This should be a rewarding evening and an opportunity to resolve your gardening problems. Noel has a wonderful garden in Berowra, Margaret runs the propagation house for the Group and Bill has a wealth of knowledge of native plants and how to grow them.

September 11th


Ross Rapmund


Restoration of shale forests in the Hornsby Shire

Background: Ross is manager of the Pennant Hills Nursery and is well known to many people as the previous manager of the Ku-ring-gai Council Nursery. Ross is very knowledgeable of local provenance including the techniques of seed collection and propagation of local natives. Ross is also closely involved in the conservation of remnant vegetation communities in the district and will talk to us about restoration of the shale forests of the area. These include the Blue Gum High Forest and the Turpentine-Ironbark forest, both of which are listed as endangered ecological communities under the NSW Threatened Species legislation.

October 9th


Margarita Clayton


Some Hibbertias of the Sydney Region

Background: Margarita is a member of the Group and an active participant in the Walks and Talks programme. She has a strong interest in cultivating Hibbertias and will talk about their propagation and some of the species found in the Sydney region.
She co-ordinates the flower display the Ku-Ring-Gai Wildflower Garden and has given many of the lectures for Walks and Talks.  Margarita has a strong interest in cultivating Hibbertias and will talk about their propagation and some of the species found in the Sydney region.

November 13th


Mark Abell


Flora of the Grampians

Background: Mark is a member of the Group and will talk about the vegetation of the Grampians which he visited late last year. The Grampians in southwest Victoria has an extremely diverse and interesting flora including endemics such as Grampian’s Thryptomene Thryptomene calycina Grampian’s Bauera Bauera sessiflora, and a variety of forms of grevilleas.
