IBA Justification

The site was identified as internationally important for bird conservation in 2003 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2003. The most recent assessment (2010) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2010 very poor medium high
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
Forest very poor (<40%) very poor (<40%) very poor
Wetlands (inland) very poor (<40%) very poor (<40%) very poor
Artificial/Terrestrial moderate (70–90%) moderate (70–90%) poor

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Natural system modifications happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium
Human intrusions and disturbance happe­ning now few indivi­duals/small area (<10%) slow decline (1–10% over 3 gener­ations) low
Agricultural expansion and intensification past (and unlikely to return) and no longer limiting most of popul­ation/area (50–90%) rapid decline (>30% 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 Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity high
