1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2018) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
White-crowned Hornbill Berenicornis comatus	10	10	individuals	100	favourable
Helmeted Hornbill Rhinoplax vigil	10	10	individuals	100	favourable

Bushy-crested Hornbill Anorrhinus galeritus	10	10	individuals	100	favourable
Black Hornbill Anthracoceros malayanus	10	10	individuals	100	favourable
Wrinkled Hornbill Rhabdotorrhinus corrugatus	10	10	individuals	100	favourable
Plain-pouched Hornbill Rhyticeros subruficollis	3,261	700	individuals	22	very unfavourable

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	moderate (70-90%)	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Biological resource use	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Some of site covered (10-49%)	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	low
