The North Dandalup IBA supports at least 1% of the non-breeding population of the endangered Baudin's Black-Cockatoo and smaller numbers of the endangered Carnaby’s Black-Cockatoo. The IBA boundaries are defined by native vegetation within a 6 km foraging radius of non-breeding season roost sites for Baudin's Black-Cockatoo in the south-west of Western Australia. Foraging distance has been determined by research undertaken by the Western Australian Museum (T. Kirkby, Western Australian Museum, pers. comm. 2009). 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 orchards 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.
The biome-restricted Western Rosella has not been recorded in Atlas surveys but is likely to occur within the IBA. Future surveys may identify it as resident within the IBA. The forest redtail subspecies of Red-tailed Black-Cockatoo (Calyptorhynchus banksii naso) has been regularly recorded in this IBA (Atlas of Australian Birds database); this subspecies is listed as vulnerable under the federal Environment Protection and Biodiversity Conservation Act 1999.
Non-bird biodiversity: This large IBA is likely to contain a number of other threatened flora and fauna. Details of these are available from the Department of Environment and Conservation, Threatened Species and Communities Branch.
