Was the whole site covered? Yes State assessed by Habitat
Accuracy of information medium

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - nomadic grazing happening now some of area/population (10-49%) slow but significant deterioration medium
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) likely in long term (beyond 4 years) some of area/population (10-49%) slow but significant deterioration medium
Climate change and severe weather drought likely in long term (beyond 4 years) whole area/population (>90%) slow but significant deterioration medium
Climate change and severe weather storms and floods likely in long term (beyond 4 years) whole area/population (>90%) 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%) slow but significant deterioration medium
Natural system modifications fire & fire suppression - increase in fire frequency/intensity happening now majority/most of area/population (50-90%) slow but significant deterioration high
