Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Human intrusions and disturbance recreational activities happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Invasive and other problematic species and genes problematic native 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 likely in short term (within 4 years) whole area/population (>90%) very rapid to severe deterioration very high
