IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2001 high unfavourable 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
Agricultural expansion and intensification annual & perennial non-timber crops - small-holder farming happening now majority/most of area/population (50-90%) slow but significant deterioration high
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming happening now majority/most of area/population (50-90%) slow but significant deterioration high
Biological resource use fishing & harvesting aquatic resources - unintentional effects: subsistence/small scale happening now majority/most of area/population (50-90%) slow but significant deterioration high
Biological resource use gathering terrestrial plants - unintentional effects (species being assessed is not the target) happening now majority/most of area/population (50-90%) slow but significant deterioration high
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) happening now majority/most of area/population (50-90%) slow but significant deterioration high

Condition of habitat (state)
Habitat Habitat Detail Reference Area (ha) Actual Area (ha) % of habitat remaining % of carrying capacity (overall) Result
Grassland 0 0 good (> 90%) poor (40-69%) unfavourable
Wetlands (inland) Freshwater lakes and pools 0 0 good (> 90%) good (> 90%) 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) No management plan exists but the management planning process has begun Some limited conservation initiatives are in place low
