Grand spider orchid (Caladenia huegelii) recovery plan
Western Australian Government Department of Environment and Conservation, 2008
Caladenia huegelii was declared as Rare Flora as Caladenia sp. (Coastal Plain) SD Hopper 3400 in September 1987 and as Caladenia huegelii in November 1990, under the Western Australian Wildlife Conservation Act 1950. It is ranked as Critically Endangered (CR) under World Conservation Union (IUCN 2001) criterion B2ab(i,ii,iii,iv) due to the severe fragmentation of populations and the continuing decline in the extent of occurrence, area of occupancy, quality of habitat and number of locations. C. huegelii is also listed as Endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).
Threats include urban development, degraded habitat, poor recruitment, weed invasion, roadworks, firebreak maintenance, inappropriate fire regimes, recreational activities and dumping of rubbish.
This interim recovery plan will operate from April 2008 to March 2013 but will remain in force until withdrawn or replaced.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 taxon is still ranked Critically Endangered, this interim recovery plan will be reviewed after five years and the need for a full recovery plan assessed.
