IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2002. The most recent assessment (2008) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2008 moderate medium medium
Whole site assessed? State assessed by Accuracy of information
no habitat medium

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

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Biological resource use happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium
Agricultural expansion and intensification happe­ning now few indivi­duals/small area (<10%) moderate decline (10–30% over 3 gener­ations) low

Transportation and service corridors likely in long term (>4 years) few indivi­duals/small area (<10%) slow decline (1–10% over 3 gener­ations) low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Most of area (50–90%) covered (including the most critical parts for important bird species) A management plan exists, but it is out of date or not compre­hensive Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity medium
