IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2018 very high not assessed high
Was the whole site covered? Yes State assessed by unset
Accuracy of information medium

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Energy production and mining renewable energy likely in short term (within 4 years) whole area/population (>90%) very rapid to severe deterioration very high
Human intrusions and disturbance recreational activities happening now whole area/population (>90%) very rapid to severe deterioration very high
Residential and commercial development tourism and recreation areas happening now whole area/population (>90%) very rapid to severe deterioration very high

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
