IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2017 very high very unfavourable low
Was the whole site covered? Yes State assessed by Habitat
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 fishing & harvesting aquatic resources - intentional use: subsistence/sml scale happening now whole area/population (>90%) very rapid to severe deterioration very high
Human intrusions and disturbance work and other activities happening now small area/few individuals (<10%) no or imperceptible deterioration low

Condition of habitat (state)
Habitat Habitat Detail Reference Area (ha) Actual Area (ha) % of habitat remaining % of carrying capacity (overall) Result
Forest 0 0 - good (> 90%) near favourable

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site (50-90%) covered (including the most critical parts for important bird species) A management plan exists but it is out of date or not comprehensive Some limited conservation initiatives are in place low
