IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2016 very high very 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 surface water (commercial use) happening now majority/most of area/population (50-90%) very rapid to severe deterioration very high
Residential and commercial development housing and urban areas happening now some of area/population (10-49%) very rapid to severe deterioration high
Transportation and service corridors roads and railroads likely in short term (within 4 years) some of area/population (10-49%) very rapid to severe 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) Coastal lagoons 0 0 moderate (70-90%) moderate (70-90%) unfavourable
Wetlands (inland) Salt marshes 0 0 poor (40-69%) moderate (70-90%) unfavourable

Conservation actions taken at site (response)
Conservation Designation Management Planning Conservation Action Result
Whole area of site (>90%) covered by appropriate conservation designation A management plan exists but it is out of date or not comprehensive Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
