IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2010 very high not assessed low
Was the whole site covered? Yes State assessed by unset
Accuracy of information medium

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Agricultural expansion and intensification marine and freshwater aquaculture - subsistence/artisinal aquaculture happening now whole area/population (>90%) very rapid to severe deterioration very high
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) happening now whole area/population (>90%) moderate to rapid deterioration very high
Biological resource use hunting & collecting terrestrial animals - persecution/control happening now some of area/population (10-49%) slow but significant deterioration medium
Climate change and severe weather drought happening now majority/most of area/population (50-90%) slow but significant deterioration high
Energy production and mining renewable energy likely in long term (beyond 4 years) some of area/population (10-49%) moderate to rapid deterioration medium
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
Invasive and other problematic species and genes problematic native species/diseases - unspecified species happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Natural system modifications dams & water management/use - dams (size unknown) happening now whole area/population (>90%) very rapid to severe deterioration very high
Natural system modifications fire & fire suppression - increase in fire frequency/intensity happening now small area/few individuals (<10%) no or imperceptible deterioration low
Residential and commercial development tourism and recreation areas likely in long term (beyond 4 years) some of area/population (10-49%) slow but significant deterioration medium

Conservation actions taken at site (response)
Conservation Designation Management Planning Conservation Action Result
Most of site (50-90%) covered (including the most critical parts for important bird species) No management planning has taken place Very little or no conservation action taking place low
