Human intrusions and disturbance	recreational activities	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low
Invasive and other problematic species and genes	invasive non-native/alien species/diseases - named species	past (and unlikely to return) and no longer limiting	whole area/population (>90%)	very rapid to severe deterioration	low
Residential and commercial development	commercial and industrial development	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
