Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2017 very high unfavourable high
Was the whole site covered? No State assessed by Habitat
Accuracy of information medium

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Biological resource use logging & wood harvesting - intentional use: subsistence/small scale past (and unlikely to return) and no longer limiting whole area/population (>90%) slow but significant deterioration low
Biological resource use logging & wood harvesting - unintentional effects: large scale happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Human intrusions and disturbance work and other activities likely in long term (beyond 4 years) majority/most of area/population (50-90%) very rapid to severe deterioration high
Residential and commercial development housing and urban areas happening now majority/most of area/population (50-90%) very rapid to severe deterioration very high

Condition of habitat (state)
