Site details
Site description: This IBA is defined for Spotted Gum and other flowering eucalypts used by Swift Parrots. The current IBA boundary is approximate based largely on surveys in 2009 that recorded Swift Parrots in Spotted Gum forests between Ulladulla and Merimbula. The IBA boundary follows the estimated extent of Spotted Gum forests, extending about 10 km inland of the coast between Ulladulla and Merimbula, but further surveys are needed to refine the boundary, particularly its inland (western) extent. The IBA also includes forests dominated by a range of other eucalpys, of which various ironbarks and bloodwoods are likley to support Swift Parrots in years in whcih the Spotted Gums are not flowering. The IBA also includes large areas of cattle-grazed pasture between forest blocks, and small areas of urban development and agriculture. These artifical habitats are likely to be of some value to Swift Parrots which utilise scattered large flowering tress and small remnants of native vegetation in otherwise modified landscapes.
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: There have been occasional scattered records of the endangered Regent Honeyeater in the IBA.
Other site values: State government (state forest, protected areas and leasehold properties); private.

Threats
Summary of threats to biodiversity at KBA: Ensure that residential and industrial development conserves Spotted Gum forests, and develop appropriate forestry prescriptions that allow for the protection of adequate amounts of habitat at known and potential Swift Parrot sites within the IBA.
