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
Natural system modifications dams & water management/use - abstraction of ground water (agricultural use) happening now small area/few individuals (<10%) slow but significant deterioration low
Natural system modifications other ecosystem modifications happening now small area/few individuals (<10%) slow but significant deterioration low
Pollution agricultural & forestry effluents - nutrient loads happening now some of area/population (10-49%) slow but significant deterioration medium
Pollution domestic & urban waste water - sewage happening now some of area/population (10-49%) slow but significant deterioration medium
