Upcoming meetings 

 14 February 2020

Speaker
  SSimon Leake 
 Topic   " The soils and vegetation of Barangaroo Headland Park " 
 Background 

Simon will describe how plantings and thriving vegetation have been successfully established in the public spaces at Barangaroo.

For this project, commonly available recycled inorganic resources (crushed sandstone and recycled sand from building excavation) were combined with composted wood mulch screened from green garden waste collections and used to recreate a three-tiered replacement soil landscape for Barangaroo. The mulch layer or “O” (for organic) horizon would be analogous to the forest litter layer; the topsoil or A horizon, a well-drained sandy soil containing nutrients, organic matter and biological life and the Subsoil or B horizon, a well-drained water holding layer for root anchorage and moisture reserve. https://sesl.com.au/projects/barangaroo-headland-park/

Simon is a soil scientist extraordinaire who leads a team with extensive achievements in rehabilitation, reconstruction and renewal of diverse urban projects and mine sites.

 Speaker
  Jayden Walsh
 Topic  "Flora and Fauna of Ku-Ring-Gai Chase National Park.'
 Background


Jayden Walsh will give an insightful presentation on the Fauna and it's connections to the Flora of Ku-ring-gai Chase NP. Come along to learn about rare and infrequently sighted wildlife that calls our backyard home and how it utilises the unique flora of Sandstone escarpments."
Jayden has been studying the wildlife in Ku-ring-gai Chase National Park since he was a high school student and has done several presentations for "Wildthings”.


12 April 2019

 Speaker   Linda Groom 
 Topic  "Save Kosci Walk"   
 Background


In November-December 2018, five people walked 560 kilometres from Sydney to the summit of Kosciuszko. On the way they were joined by hundreds of supporters, some strong-legged, some simply determined. Why bother?

The walk sought stronger action from the NSW government to reduce damage caused by feral animals, particularly wild horses, in Kosciuszko National Park. Wild horses are recognized by the NSW Office of Environment and Heritage as threats to at least 9 plant species, including 2 orchids, as well as to sphagnum bogs.

The talk gives a brief introduction to these species and the mechanisms by which wild horses pose a threat to them, then describes the protest walk and the public reactions to the walk. The issue of horses in national parks remains a controversial issue, but the presenter sees some hope that it can be resolved by emphasizing the positive – in this case the beauty of national parks – and by raising awareness of the environmental impacts of the horses.  

Presenter

Linda Groom’s most recent volunteer position was Convenor of Save Kosci Inc. She was formerly Curator of Pictures at the National Library, Convenor of the National Photography Festival, past-President of the Canberra Bushwalking Club and president of a number of national professional organisations. She has no botanical qualifications

 

10 May 2019

 Speaker

   John Whale, APS Scholarship Recipient

 Topic

  "Genetic Variation in Red Gum Species"

 Background


 The details will be available soon


14 June 2019

 Speaker

  Wendy Grimm, APS member 

 Topic

  "Native Pollinators"

 Background


Photo: Chloropid fly on flower of Corunastylis fimbriata.

 What motivates insects to visit plants? How do plants deceive insects into providing pollination services?

These questions have tied Wendy’s interest in Australian native plants to her passion for capturing images of small, mostly inconspicuous insects. She will talk about insect pollinator relationships in several well-known plant families



12 July 2019

 Speaker

 Jacob Sife, Natural Areas Program Leader, Ku-ring-gai Council

 Topic

  ‘Collaborating for conservation in Ku-ring-gai’

 Background

 

Ku-ring-gai is known as a biodiversity hotspot and a refuge for many species of flora and fauna struggling to survive in the highly urbanised Sydney basin. Ku-ring-gai Council manage numerous native and threatened species, populations and ecological communities in an effort to protect, conserve and enhance our biodiversity. Critical to the success of conservation programs are the collaborations formed with community and Government bodies. In this talk, Jacob will look at the conservation programs in Ku-ring-gai, particularly those which have received funding through the State Government’s Saving our Species or Ku-ring-gai Council’s Environment Levy, he will share data on outcomes and the most up to date monitoring on some of our most endangered species, including the critically endangered Hibbertia spanantha. The details will be available soon


2 August 2019

 Speaker

   Ron Gornall, APS Member. 

 Topic

  " An Interactive plant ID session"

 Background

 Long time APS member Ron Gornall will lead an Interactive Plant

Identification session. Members are encouraged to bring in plants they need identifying or help with growing tips.


13 September 2019

 Speaker

  Susan Everingham, APS Scholarship Recipient 

 Topic

  " Changes in Sydney Flowering Times"

 Background

Flowering phenology (time of flowering events) relies heavily on cues from environmental conditions, particularly temperature. Studies have shown that for many plants species, flowering dates are occurring earlier in the season due to increases in atmospheric temperature because of anthropogenic climate change. My study aims to investigate existing flowering time changes across the Sydney region. I have used an old data set of flowering time collected by Price in 1963, combined with a resampling of a subset of plant species flowering time during 2018-2019 to determine if Sydney flora is flowering earlier in the season as time progresses.


11 October 2019

 Speakers

  Sue Bowen and Margaret Hamilton, APS Members 

 Topic

  " Propagation Demonstration"

 Background

Dr Sue Bowen (President) and Margaret Hamilton (Propagation team leader) will lead a practical workshop on propagating native plants from cuttings and seeds. Attendees are asked to bring their own, labelled plant material and seeds to the workshop. The plant material is to be non-flowering, firm, new-growth and is to be placed in damp, plastic bags. Participants will learn how to prepare and pot-up cuttings and seeds to take home to grow and/or donate to the propagation team.

 

November 2019

 Speaker

  Robin Buchanan
