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 likely in long term (beyond 4 years) small area/few individuals (<10%) slow but significant 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%) slow but significant deterioration medium
Energy production and mining mining and quarrying likely in short term (within 4 years) small area/few individuals (<10%) moderate to rapid deterioration low
Human intrusions and disturbance recreational activities happening now some of area/population (10-49%) slow but significant deterioration medium
Human intrusions and disturbance work and other activities happening now whole area/population (>90%) no or imperceptible deterioration low
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 some of area/population (10-49%) no or imperceptible deterioration low
Natural system modifications other ecosystem modifications happening now small area/few individuals (<10%) no or imperceptible 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90%) covered by appropriate conservation designation A management plan exists but it is out of date or not comprehensive Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
