IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2021) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2021 good very high high
Whole site assessed? State assessed by Accuracy of information
yes habitat good

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Forest good (>90%) good (>90%) good

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Biological resource use happe­ning now whole of popul­ation/area (>90%) moderate decline (10–30% over 3 gener­ations) very high
Transportation and service corridors happe­ning now few indivi­duals/small area (<10%) slow decline (1–10% over 3 gener­ations) low
Residential and commercial development happe­ning now few indivi­duals/small area (<10%) no or slight decline (<1% over 3 gener­ations) low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Whole area (>90%) covered by appropriate conservation designation A compre­hensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species The conservation measures needed for the site are being compre­hensively and effectively implemented high
