Orchid Conservation

2019 Orchid Conservation Symposium, 18th-19th June, Domain House 

17% of all of Australia’s Nationally threatened flora are orchids, with the majority of these species found in south eastern Australia, making orchid conservation a national priority. The RBGV Orchid Conservation Symposium will bring together community groups, practitioners and scientists in a workshop (see the Programme of events) to engage and educate the community on current conservation research in the field and to increase collaboration between the community, practitioners and scientists. Increased knowledge sharing and network building through collaborations will reduced the risk of vulnerable or near threatened species becoming endangered.

The dates of the workshop are 18th and 19th of June 2019. The venue is Domain House at the RBGV South Yarra site, Melbourne.

With over 28,000 species, orchids are one of the largest plant families in the world. Australia is home to more than 1,800 species of orchid - the majority being ground-dwelling (terrestrial) in the temperate south of the country. Victoria has in excess of 400 species of native orchids with many occurring nowhere else on Earth. Their habitats vary from our alpine peaks to semi-arid mallee, in swamps, native grasslands, heath lands, and eucalypt forests of all types. The majority of our native orchids emerge from an underground tuber in late autumn, flower in late winter/early spring and set seed before the summer, when they retreat back to their underground tuber. All orchids are reliant on a particular type of mycorrhizal fungi in order to germinate in the wild and are often pollinated by only one species of insect. 

About Orchids


To continue the conservation of orchids we are currently seeking funding for propagation, pollinator distribution studies and reintroduction of five of Victoria’s most threatened species. We hope to raise $100,000 for each of: Caladenia amoena (Charming Spider-orchid), Caladenia audasii (Audas Spider-orchid), Caladenia pumila (Dwarf Spider-orchid), Caladenia rosella (Little Pink Spider-orchid) and Thelymitra mackibbinii (Brilliant Sun-orchid). If you would like to support the work of the Orchid Conservation Program, please consider making a tax-deductible donation through the Royal Botanic Gardens Victoria Foundation.

Orchid Conservation at Royal Botanic Gardens Victoria is entirely supported by grants and individual donations. Donations from members of the public are critical and our entire lab has been fitted out thanks to the generous donations of individuals and foundations including the Australian Orchid Foundation, The Australian Communities Foundation, The Australasian Native Orchid Society, local community groups and amazing individuals.

Why do orchids need help?

Many of our native orchids are at risk of extinction. Alarmingly, 17% of all nationally threatened plants in Australia are orchids, more than any other plant family. The causes of these declines include: historic land clearing, introduced weeds, grazing by introduced animals and illegal poaching. Due to reduced numbers many species are now vulnerable to inbreeding depression, climate change and inappropriate fire regimes. Without our help many of these species won't be around for future generations to enjoy.

Orchid Conservation

In 2014 the Australian Network for Plant Conservation's (ANPC) Orchid Conservation Program joined with Royal Botanic Gardens Victoria under a partnership. The resulting program is now the largest of its type in the world. With our partner organisations we have undertaken over 50 reintroductions of over 20 species of endangered native orchids across Victoria, New South Wales and South Australia.


We aim to prevent extinction by:

  • Storing a genetically diverse representation of seed and mycorrhizal fungi
  • Propagating suitable numbers of each of our threatened orchids for reintroduction.
  • Reintroducing these species to protected public and private land where the appropriate vegetation, climate conditions and pollinator are present.

The Orchid Conservation Program undertakes research on all aspects of orchid ecology, including pollination, mycorrhizal associations, propagation, demographics and reintroduction science.


The key to the success of our Orchid Conservation work is collaborations and relationships with many government and non-government organisations and private individuals. The work of the Orchid Conservation Program is wonderfully supported by the following partners:

  • Victorian Government Department of Environment, Land, Water and Planning
  • Australian Network for Plant Conservation
  • Wimmera Catchment Management Authority 
  • NSW Government Office of Environment and Heritage
  • South Australian Government
  • Adelaide Botanic Gardens
  • Trust for Nature
  • Parks Victoria
  • Alcoa/Portland Aluminium
  • Murray Local Landcare Services
  • Australian National University
  • Hindmarsh Landcare Network
  • Friends of the Grampians
  • Amaryllis Environmental
  • Nilumbik Shire
  • RMIT University
  • Private landholders

The work of countless volunteers has been critical to the success of Orchid Conservation and in particular volunteers from the Australasian Native Orchid Society - Victorian Branch.
