Agricultural expansion and intensification	annual & perennial non-timber crops - agro-industry farming	happening now	small area/few individuals (<10%)	very rapid to severe deterioration	low
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
Human intrusions and disturbance	recreational activities	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Invasive and other problematic species and genes	invasive non-native/alien species/diseases - named species	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
