Threats to the site (pressure)
Threat Level 1	Threat Level 2	Timing	Scope	Severity	Result
Energy production and mining	renewable energy	likely in short term (within 4 years)	small area/few individuals (<10%)	moderate to rapid deterioration	low
Human intrusions and disturbance	recreational activities	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
