Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2020 high not assessed medium
Was the whole site covered? Yes State assessed by unset
Accuracy of information medium

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 small area/few individuals (<10%) very rapid to severe deterioration low
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) happening now small area/few individuals (<10%) slow but significant deterioration low
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 - named species happening now some of area/population (10-49%) very rapid to severe deterioration high
Natural system modifications dams & water management/use - abstraction of surface water (agricultural use) happening now small area/few individuals (<10%) moderate to rapid deterioration low
Pollution excess energy - noise pollution happening now some of area/population (10-49%) very rapid to severe deterioration high
Residential and commercial development housing and urban areas happening now small area/few individuals (<10%) moderate to rapid deterioration low

Conservation actions taken at site (response)
Conservation Designation Management Planning Conservation Action Result
Whole area of site (>90%) covered by appropriate conservation designation A management plan exists but it is out of date or not comprehensive Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
