Threats to the site (pressure)
Threat level 1	Threat level 2	Timing	Scope	Severity	Result
Agricultural expansion and intensification	annual & perennial non-timber crops - shifting agriculture	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Biological resource use	hunting & collecting terrestrial animals - unintentional effects (species is not the target)	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Energy production and mining	mining and quarrying	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Human intrusions and disturbance	work and other activities	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Transportation and service corridors	roads and railroads	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
