2009 very high unfavourable low
Was the whole site covered? Yes State assessed by Habitat
Accuracy of information good

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Agricultural expansion and intensification annual & perennial non-timber crops - agro-industry farming happening now whole area/population (>90%) very rapid to severe deterioration very high
Agricultural expansion and intensification annual & perennial non-timber crops - small-holder farming happening now majority/most of area/population (50-90%) very rapid to severe deterioration very high
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
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
Climate change and severe weather drought happening now some of area/population (10-49%) slow but significant deterioration medium
Human intrusions and disturbance work and other activities happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Invasive and other problematic species and genes invasive non-native/alien species/diseases - named species happening now whole area/population (>90%) moderate to rapid deterioration very high
Natural system modifications dams & water management/use - abstraction of surface water (agricultural use) happening now majority/most of area/population (50-90%) slow but significant deterioration high
