Site details


Site description: The Jalbarragup IBA supports at least 1% of the breeding population of the endangered Carnaby’s Black-Cockatoo and small numbers of the breeding population of the endangered Baudin’s Black-Cockatoo. The IBA boundaries are defined by native vegetation within a 10 km foraging radius of the locality of Jalbarragup in the deep south-west of Western Australia. The foraging radius is based on Western Australian Museum data for low density nests of Carnaby’s Black-Cockatoo in forest areas (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.
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 forest redtail subspecies of Red-tailed Black-Cockatoo (Calyptorhynchus banksii naso) is listed as vulnerable under the federal Environment Protection and Biodiversity Conservation Act 1999. This subspecies is likely to be a breeding resident of the IBA (T Kirkby, Western Australian Museum, pers. comm. 2009). 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.
Other site values: Private landholders (orchardists, farmers, townsite residents); nature reserves, national parks and state forests (Department of Environment and Conservation); local government; service providers (Western Power); Water Corporation. Access to private land and areas with restricted access must be arranged with individual land-holders.

Threats


Summary of threats to biodiversity at KBA: European Honeybee (feral bee) control and mitigation of illegal shooting, particularly for Baudin's Black-Cockatoo. Active prevention of fruit crop damage by Baudin’s Black-Cockatoo by permanent netting and scaring by gas guns and shooting to scare (DEC 2008).
