Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2022 very high not assessed medium
Was the whole site covered? Yes State assessed by unset
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 whole area/population (>90%) very rapid to severe deterioration very high
Biological resource use fishing & harvesting aquatic resources - intentional use: subsistence/sml scale happening now small area/few individuals (<10%) no or imperceptible deterioration low
Biological resource use hunting & collecting terrestrial animals - unintentional effects (species is not the target) happening now majority/most of area/population (50-90%) very rapid to severe deterioration very high
Human intrusions and disturbance recreational activities happening now some of area/population (10-49%) slow but significant deterioration medium
Pollution domestic & urban waste water - run-off happening now some of area/population (10-49%) slow but significant deterioration medium
Residential and commercial development housing and urban areas likely in long term (beyond 4 years) some of area/population (10-49%) slow but significant deterioration medium
Transportation and service corridors roads and railroads happening now small area/few individuals (<10%) slow but significant deterioration low
