IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2013 very high not assessed negligible
Was the whole site covered? Yes State assessed by unset
Accuracy of information unknown

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%) slow but significant deterioration medium
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%) moderate to rapid deterioration high
Invasive and other problematic species and genes problematic native species/diseases - unspecified species likely in short term (within 4 years) whole area/population (>90%) no or imperceptible deterioration low
Natural system modifications dams & water management/use - dams (size unknown) likely in long term (beyond 4 years) whole area/population (>90%) no or imperceptible deterioration low

Conservation actions taken at site (response)
Conservation Designation Management Planning Conservation Action Result
Little/none of site covered (<10%) No management planning has taken place Some limited conservation initiatives are in place negligible
