Year of assessment (most recent) State (condition) Pressure (threat) Response (action)
2009 not assessed very high low
Was the whole site assessed? State assessed by Accuracy of information
yes unset poor

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Invasive and other problematic species and genes invasive non-native/alien species/diseases - named species happening now majority/most of area/population (50-90%) very rapid to severe deterioration very high
Natural system modifications fire & fire suppression - increase in fire frequency/intensity likely in long term (beyond 4 years) some of area/population (10-49%) very rapid to severe deterioration medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation action Result
Some of site covered (10-49%) Unknown Some limited conservation initiatives are in place low
