Agricultural expansion and intensification annual & perennial non-timber crops - small-holder farming likely in long term (beyond 4 years) some of area/population (10-49%) slow but significant deterioration medium
Invasive and other problematic species and genes invasive non-native/alien species/diseases - unspecified species likely in long term (beyond 4 years) majority/most of area/population (50-90%) slow but significant deterioration medium
Natural system modifications fire & fire suppression - increase in fire frequency/intensity likely in long term (beyond 4 years) small area/few individuals (<10%) no or imperceptible deterioration low
