Site details
Site description: The Koobabbie IBA supports at least 1% of the breeding population of Carnaby's Black-Cockatoo. The IBA boundaries are defined by known areas of suitable nesting habitat and other remnant vegetation. The IBA is located in the northern wheatbelt of Western Australia and is comprised of salmon gum woodland remnants and isolated trees providing nesting sites. Pasture, crops, non-native plants and weed populations are not included in the IBA. The IBA has a Mediterranean climate.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that meets the thresholds for at least one criterion described in the Global Standard for the Identification of KBAs.
Additional biodiversity: The vulnerable Malleefowl and near-threatened Australian Bustard have been observed in the IBA but are not resident. Non-bird biodiversity: Declared Rare Flora in this IBA include Eremophila koobabbiensis and Halosarcia koobabbiensis (both known only from this IBA); Ptilotus caespitulosus, Chrosiema humile, Caladenia drakeoides and Acacia vassalali; a single specimen of Eremophila sargentii is Priority One flora (Doley 2005).
Other site values: A single private landholder. Contact Birds Australia Western Australia's Carnaby's Black-Cockatoo Recovery Project for access details related to private land.
