1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (1994) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1994. The most recent assessment (1994) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Biological resource use	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Transportation and service corridors	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	slow but significant deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Not assessed	Not assessed	Not assessed	not assessed
