Summary
Caladenia melanema was declared as Rare Flora in 2004 under the Western Australian Wildlife Conservation Act 1950 and is currently ranked as Critically Endangered (CR) in Western Australia against World Conservation Union (IUCN 2001) Red List criteria B2ab(iii); C2a(ii), due to the species area of occupancy being less than 10 km2 with total population size numbering fewer than 250 mature individuals with no subpopulation containing more than 50 mature individuals and a continuing decline in the areal extent and quality of habitat. The species is also listed as Critically Endangered under the Commonwealth Environment Protection Biodiversity Conservation Act 1999 (EPBC Act 1999).
The main threats to the species are road maintenance, grazing, salinity, weed invasion, inappropriate fire regimes and small population size. Caladenia melanema is known from one population (two subpopulations) totaling approximately 33 mature plants near Pingrup in DEC’s Great Southern District.
