The site was identified as important in 2001 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List1	Season	Year(s)	Size	IBA criteria
Black Partridge Melanoperdix niger	VU	resident	2000	present	A1, A3
Malay Crestless Fireback Lophura erythrophthalma	CR	resident	2000	present	A1, A3
White-winged Duck Asarcornis scutulata	CR	resident	2000	present	A1
Lesser Adjutant Leptoptilos javanicus	NT	resident	2000	present	A1
Storm's Stork Ciconia stormi	EN	resident	2000	present	A1, A3
Malay Blue-banded Kingfisher Alcedo peninsulae	NT	resident	2000	present	A1, A3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2001) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2012) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Agricultural expansion and intensification	past (and unlikely to return) and no longer limiting	some of area/population (10-49%)	very rapid to severe deterioration	low
Energy production and mining	past (and unlikely to return) and no longer limiting	some of area/population (10-49%)	slow but significant deterioration	low
Transportation and service corridors	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Human intrusions and disturbance	past (and unlikely to return) and no longer limiting	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>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
