IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2006 medium not assessed high
Was the whole site covered? Yes State assessed by unset
Accuracy of information good

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming happening now small area/few individuals (<10%) no or imperceptible deterioration low
Biological resource use gathering terrestrial plants - unintentional effects (species being assessed is not the target) happening now some of area/population (10-49%) slow but significant deterioration medium
Natural system modifications fire & fire suppression - increase in fire frequency/intensity likely in short term (within 4 years) small area/few individuals (<10%) slow but significant deterioration low

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

Scientific Common TargetPop ActualPop Units Remaining Result
Bugeranus carunculatus Wattled Crane 15 29 adults 100 favourable
Anthropoides paradiseus Blue Crane 15 12 adults 80 near favourable

Conservation actions taken at site (response)
Conservation Designation Management Planning Conservation Action Result
Whole area of site (>90%) covered by appropriate conservation designation A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity high
