Threats to the site (pressure)
Threat Level 1	Threat Level 2	Timing	Scope	Severity	Result
Agricultural expansion and intensification	annual & perennial non-timber crops - small-holder farming	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Biological resource use	hunting & collecting terrestrial animals - unintentional effects (species is not the target)	likely in short term (within 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
Biological resource use	logging & wood harvesting - unintentional effects: subsistence/small scale	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Human intrusions and disturbance	war, civil unrest and military exercises	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low
Natural system modifications	fire & fire suppression - increase in fire frequency/intensity	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Residential and commercial development	housing and urban areas	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Transportation and service corridors	roads and railroads	happening now	small area/few individuals (<10%)	slow but significant deterioration	low

Condition of habitat (state)
Habitat	Habitat Detail	Reference Area (ha)	Actual Area (ha)	% of habitat remaining	% of carrying capacity (overall)	Result
Forest		80000	63000	-	moderate (70-90%)	unfavourable

Conservation actions taken at site (response)
Conservation Designation	Management Planning	Conservation 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
