IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2016 very high unfavourable medium
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
Natural system modifications dams & water management/use - abstraction of ground water (domestic use) likely in short term (within 4 years) whole area/population (>90%) very rapid to severe deterioration very high
Transportation and service corridors flight paths happening now some of area/population (10-49%) moderate to rapid deterioration high

Condition of habitat (state)
Habitat Habitat Detail Reference Area (ha) Actual Area (ha) % of habitat remaining % of carrying capacity (overall) Result
Wetlands (inland) 0 0 moderate (70-90%) moderate (70-90%) unfavourable

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site (50-90%) covered (including the most critical parts for important bird species) A management plan exists but it is out of date or not comprehensive Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
