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

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) happening now some of area/population (10-49%) slow but significant deterioration medium
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 - unspecified species happening now whole area/population (>90%) moderate to rapid deterioration very high
Natural system modifications dams & water management/use - dams (size unknown) happening now whole area/population (>90%) very rapid to severe deterioration very high
Natural system modifications fire & fire suppression - increase in fire frequency/intensity happening now majority/most of area/population (50-90%) no or imperceptible deterioration low
Pollution domestic & urban waste water - type unknown/unrecorded happening now some of area/population (10-49%) no or imperceptible deterioration low
Pollution excess energy - noise pollution happening now some of area/population (10-49%) no or imperceptible deterioration low
