IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2008 low near favourable low
Was the whole site covered? Yes State assessed by Habitat
Accuracy of information good

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) past (and unlikely to return) and no longer limiting majority/most of area/population (50-90%) moderate to rapid deterioration low

Condition of habitat (state)
Habitat Habitat Detail Reference Area (ha) Actual Area (ha) % of habitat remaining % of carrying capacity (overall) Result
Wetlands (inland) Standing brackish and salt water 0 0 good (> 90%) moderate (70-90%) near favourable

Conservation actions taken at site (response)
Conservation Designation Management Planning Conservation Action Result
Some of site covered (10-49%) No management planning has taken place Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity low
