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	majority/most of area/population (50-90%)	slow but significant deterioration	high
Biological resource use	hunting & collecting terrestrial animals - intentional use (species being assessed is the target)	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Residential and commercial development	housing and urban areas	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Transportation and service corridors	roads and railroads	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Condition of habitat (state)
Habitat	Habitat Detail	Reference Area (ha)	Actual Area (ha)	% of habitat remaining	% of carrying capacity (overall)	Result
Artificial - terrestrial	Rice paddies	0	0	moderate (70-90%)	moderate (70-90%)	unfavourable
Shrubland		0	0	moderate (70-90%)	moderate (70-90%)	unfavourable

Conservation actions taken at site (response)
Conservation Designation	Management Planning	Conservation Action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	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	medium
