Accuracy of information good

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Agricultural expansion and intensification annual & perennial non-timber crops - small-holder farming happening now some of area/population (10-49%) no or imperceptible deterioration low
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming happening now some of area/population (10-49%) no or imperceptible deterioration low
Biological resource use logging & wood harvesting - unintentional effects: subsistence/small scale past (and unlikely to return) and no longer limiting some of area/population (10-49%) slow but significant deterioration low
Human intrusions and disturbance recreational activities happening now some of area/population (10-49%) no or imperceptible deterioration low
Invasive and other problematic species and genes invasive non-native/alien species/diseases - unspecified species happening now whole area/population (>90%) very rapid to severe deterioration very high
