Site details
Site description: The Gillingarra 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 associated feeding habitat. The IBA is comprised of isolated Marri paddock trees providing nesting sites and a large area of intact proteaceous heath providing food sources for nesting birds. Pasture, crops, non-native plants and weed populations are not included in the IBA. The area 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: Additional bird surveys may show that other significant species are present in the IBA.
Other site values: Private; state government (Department of Environment and Conservation). Contact Birds Australia Western Australia's Carnaby's Black-Cockatoo Recovery Project for access details related to private land.
