Preventing the extinction of the Buchan River grevillea in Victoria
As part of the The ‘Preventing the extinction of Victoria’s threatened flora’ project, horticulturists and scientist have been surveying for, collecting seed, and propagating the critically endangered Grevillea pachylostyla (Buchan River grevillea). These collections will form the basis of an insurance collection and seed orcharding program, safeguarding the future of this species. This elusive, sprawling shrub is known only from deep chasms and steep rocky outcrops in some of Victoria’s most remote alpine areas, making conservation efforts challenging.
This species can now be found in Royal Botanic Gardens Victoria’s conservation collections. The species’ conflorescences (compound flower stems) are cream coloured and gradually change colour to pinkish red as each individual flower reaches anthesis (opening).
Grevillea pachylostyla can be seen flowering now in the Research Garden and Stringybark Garden beds at Cranbourne Gardens—get in before it’s too late!
This research is funded by Department of Energy, Environment and Climate Action‘s Nature Fund.
The ‘Preventing the extinction of Victoria’s threatened flora’ project is led by Royal Botanic Gardens Victoria in partnership with La Trobe University, Australian Network for Plant Conservation, DEECA, Trust for Nature, Wimmera Catchment Management Authority, Nillumbik Shire, ENVITE, Bairnsdale & District Field Naturalists Club, Friends of the Grampians Gariwerd, WAMA Botanic Gardens, Halls Gap Botanic Gardens and the Australasian Native Orchid Society Victorian Branch.
