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%)	slow but significant deterioration	medium
Climate change and severe weather	habitat shifting and alteration	likely in long term (beyond 4 years)	whole area/population (>90%)	no or imperceptible deterioration	low
Pollution	excess energy - light pollution	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Pollution	industrial & military effluents - oil spills	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low
