Site description (2008 baseline):
Site location and context
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.
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).
Pressure/threats to key biodiversity
Ongoing nest competitor control. Planting appropriate native food plant species near nesting areas.
Conservation responses/actions for key biodiversity
The conservation of native vegetation, flora and fauna, including the endangerd Carnaby's Black-Cockatoo, has been a long-standing action by the landholder in this IBA and a nature conservation covenant is being instituted to protect the farm's biodiversity in perpetuity. By 1970, the fencing of 1857 ha of native vegetation was underway for the conservation of cockatoos and other taxa. Planting native plant species has been undertaken in fenced remnant vegetation and to provide corridors between remnants. An extensive corridor project extends from the salt lake system on the Koobabbie IBA. The active control of nest competitors such as Galah and Western Corella commenced in 1997; an artificial nest hollow trial commenced in 2004 (Doley 2005). Nest hollow repairs have been undertaken as part of a broader nest hollow repair initiative for Carnaby's Black-Cocaktoo recovery.
