1994 high near favourable medium
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) - small-holder grazing, ranching or farming happening now small area/few individuals (<10%) no or imperceptible deterioration low
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) happening now some of area/population (10-49%) very rapid to severe deterioration high
Human intrusions and disturbance war, civil unrest and military exercises past (and unlikely to return) and no longer limiting whole area/population (>90%) moderate to rapid deterioration low
Natural system modifications dams & water management/use - abstraction of surface water (agricultural use) happening now whole area/population (>90%) slow but significant deterioration high
