Threats to the site (pressure)
Threat Level 1	Threat Level 2	Timing	Scope	Severity	Result
Agricultural expansion and intensification	livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Agricultural expansion and intensification	marine and freshwater aquaculture - industrial aquaculture	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	fishing & harvesting aquatic resources - unintentional effects: large scale	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	hunting & collecting terrestrial animals - unintentional effects (species is not the target)	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
