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

State (condition of the trigger species' habitats)
Habitat	Habitat detail	Reference area (ha)	Actual area (ha)	Habitat quantity (% remaining)	Habitat quality (carrying capacity)	Result
Forest		24710	23270	-	-	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1	Threat level 2	Timing	Scope	Severity	Result
Agricultural expansion and intensification	annual & perennial non-timber crops - shifting agriculture	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
Biological resource use	hunting & collecting terrestrial animals - unintentional effects (species is not the target)	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Biological resource use	logging & wood harvesting - unintentional effects: subsistence/small scale	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Energy production and mining	mining and quarrying	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Pollution	industrial & military effluents - type unknown/unrecorded	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
Transportation and service corridors	roads and railroads	past (and unlikely to return) and no longer limiting	small area/few individuals (<10%)	moderate to rapid deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation	Management planning	Other conservation action	Result
Little/none of site covered (<10%)	No management plan exists but the management planning process has begun	Some limited conservation initiatives are in place	low
