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 small area/few individuals (<10%) slow but significant deterioration low
Climate change and severe weather drought likely in short term (within 4 years) majority/most of area/population (50-90%) slow but significant deterioration medium
Human intrusions and disturbance recreational 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%) moderate to rapid deterioration high
Natural system modifications fire & fire suppression - increase in fire frequency/intensity happening now some of area/population (10-49%) no or imperceptible deterioration low
Pollution agricultural & forestry effluents - herbicides and pesticides happening now some of area/population (10-49%) slow but significant deterioration medium
Residential and commercial development tourism and recreation areas happening now whole area/population (>90%) no or imperceptible deterioration low
Transportation and service corridors roads and railroads happening now small area/few individuals (<10%) moderate to rapid deterioration low

Condition of habitat (state)
Habitat Habitat Detail Reference Area (ha) Actual Area (ha) % of habitat remaining % of carrying capacity (overall) Result
Forest 0 0 good (> 90%) moderate (70-90%) near favourable
Grassland 0 0 moderate (70-90%) moderate (70-90%) unfavourable
Shrubland 0 0 good (> 90%) moderate (70-90%) near favourable

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90%) covered by appropriate conservation designation A management plan exists but it is out of date or not comprehensive Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
