Summary
Caladenia procera was declared to be Rare Flora under the Western Australian Wildlife Conservation Act 1950 in April 2002 and is currently ranked as Critically Endangered (CR) in WA under International Union for Conservation of Nature (IUCN 2001) Red List. The species is listed under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) as Critically Endangered. The main threats are: clearing for development, road, firebreak and power utility maintenance, weed invasion, inappropriate fire regimes and grazing.
Caladenia procera is currently known from a linear range of less than 15 km to the south-west of Busselton, where it grows in Jarrah, Marri and Peppermint woodland on alluvial sandy-clay loam flats with Anigozanthos manglesii (Hopper and Brown 2001), and also from a disjunct occurrence some 70 km north near Kemerton.
The objective of this plan is to abate identified threats and maintain or enhance in situ populations to ensure the long-term preservation of the species in the wild.
