Threats to the site (pressure)
Threat level 1	Threat level 2	Timing	Scope	Severity	Result
Biological resource use	fishing & harvesting aquatic resources - unintentional effects: large scale	happening now	some of area/population (10-49%)	no or imperceptible 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%)	no or imperceptible deterioration	low
Human intrusions and disturbance	recreational activities	likely in long term (beyond 4 years)	whole area/population (>90%)	slow but significant deterioration	medium
Invasive and other problematic species and genes	invasive non-native/alien species/diseases - named species	happening now	whole area/population (>90%)	no or imperceptible deterioration	low
