Site description
The Northern Swan Coastal Plain IBA supports a considerable portion of the non-breeding population of the endangered Carnaby's Black-Cockatoo and a small number of breeding pairs. The IBA is bounded by the Moore River to the north, Darling Range to the east, Swan River to the south and the coast and Indian Ocean to the west. The IBA includes all native vegetation remnants in Spearwood and Bassendean North Heddle vegetation types (Western Australian Government 2000), both known to be productive for Carnaby’s Black-Cockatoo. Further suveys may indicate that the IBA could be extended north or south where the status of Carnaby's Black-Cockatoo is currently less well known. Pine plantations, which are known to support large numbers of Carnaby’s Cockatoo in the non-breeding season (Johnstone et al. 2008), are included in the IBA. The IBA consists of all native vegetation greater than 1 ha on private land, water catchment areas, state forests, nature reserves and other reserves. Pasture, crops, non-native plants, weed species and market gardens are excluded from the IBA. The 1 ha minimum native vegetation criterion has been determined by experts in a consultation process undertaken by the Australian Government (C. Gole pers. comm. 2009). The area has a Mediterranean climate.

Key biodiversity
The biome-restricted Regent Parrot and White-breasted Robin have been recorded in a very small number of surveys (Atlas of Australian Birds database). The biome-restricted Western Yellow Robin has been recorded in a small number of surveys (Brooker 2004; Atlas of Australian Birds database). The biome-restricted Red-eared Firetail has been recorded at Whiteman Park (Brooker 2004).
