IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2018 high very unfavourable high
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
Climate change and severe weather storms and floods likely in short term (within 4 years) whole area/population (>90%) moderate to rapid deterioration high
Human intrusions and disturbance recreational activities happening now small area/few individuals (<10%) no or imperceptible deterioration low
Human intrusions and disturbance work and other activities happening now some of area/population (10-49%) no or imperceptible deterioration low
Invasive and other problematic species and genes invasive non-native/alien species/diseases - unspecified species past (and unlikely to return) and no longer limiting whole area/population (>90%) 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
Coastline Sand dunes & beaches 0 0 good (> 90%) good (> 90%) near favourable
Forest Dry evergreen forest (tropical) 0 0 very poor (< 40%) poor (40-69%) very unfavourable
Rocky areas (eg. inland cliffs, mountain peaks) 0 0 good (> 90%) good (> 90%) 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
