Threats to the site (pressure)
Threat Level 1	Threat Level 2	Timing	Scope	Severity	Result
Biological resource use	fishing & harvesting aquatic resources - intentional use: subsistence/sml scale	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Climate change and severe weather	habitat shifting and alteration	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	work and other activities	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Invasive and other problematic species and genes	invasive non-native/alien species/diseases - unspecified species	past (and unlikely to return) and no longer limiting	whole area/population (>90%)	slow but significant deterioration	low
