The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2004).

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 - small-holder farming	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
Agricultural expansion and intensification	livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Biological resource use	hunting & collecting terrestrial animals - intentional use (species being assessed is the target)	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Biological resource use	logging & wood harvesting - unintentional effects: subsistence/small scale	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	recreational activities	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Natural system modifications	fire & fire suppression - increase in fire frequency/intensity	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
