IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2013 medium very unfavourable low
Was the whole site covered? Yes State assessed by Habitat
Accuracy of information unknown

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Agricultural expansion and intensification annual & perennial non-timber crops - agro-industry farming happening now small area/few individuals (<10%) moderate to rapid deterioration low
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) happening now some of area/population (10-49%) slow but significant deterioration medium
Pollution industrial & military effluents - type unknown/unrecorded happening now small area/few individuals (<10%) no or imperceptible deterioration low
Residential and commercial development commercial and industrial development likely in short term (within 4 years) some of area/population (10-49%) moderate to rapid deterioration medium

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%) poor (40-69%) very 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site (50-90%) covered (including the most critical parts for important bird species) A management plan exists but it is out of date or not comprehensive Very little or no conservation action taking place low
