Some Australian native terrestrial orchids are evergreen but most temperate species die back and lie dormant over summer, then re-shoot from an underground tuber the following autumn.
There are 81 native terrestrial orchid species currently listed as threatened under the NSW Biodiversity Conservation Act (2016; June 2020); some of these species require ex situ conservation and translocation as part of an integrated plan to promote their recovery. Our research aims to ensure the long-term survival of ex situ collections of these Australian terrestrial orchid species and support translocation programs, where these are required.
