Majestic spider orchid (Caladenia winfieldii) recovery plan
Western Australian Department of Environment and Conservation, 2008
Caladenia winfieldii was declared as Rare Flora under the Western Australian Wildlife Conservation Act 1950 in December 1993 and is currently ranked as Endangered under IUCN Red List Criterion D (IUCN 2001), due to there being less than 250 mature individuals in the wild. The species is also listed as Endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).
The main threats are feral pigs, inappropriate fire regimes, kangaroo grazing, hydrological changes and dieback.
Caladenia winfieldii is currently known from a single population in Department of Environment and Conservation's Donnelly District.
This interim recovery plan will operate from April 2008 to March 2013 but will remain in force until withdrawn or replaced. It is intended that, if the species is still ranked as Endangered at the end of the five-year term, this interim recovery plan will be reviewed and the need for further recovery actions assessed.
