Threat Level 1 Threat Level 2 Timing Scope Severity Result
Biological resource use fishing & harvesting aquatic resources - unintentional effects: subsistence/small scale 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 majority/most of area/population (50-90%) slow but significant deterioration high
Residential and commercial development housing and urban areas happening now some of area/population (10-49%) no or imperceptible deterioration low
