IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2018 medium 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
Human intrusions and disturbance recreational activities likely in short term (within 4 years) small area/few individuals (<10%) slow but significant deterioration low
Human intrusions and disturbance work and other activities happening now some of area/population (10-49%) slow but significant deterioration medium
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
Residential and commercial development housing and urban areas past (and unlikely to return) and no longer limiting some of area/population (10-49%) very rapid to severe deterioration low
Residential and commercial development tourism and recreation areas likely in short term (within 4 years) some of area/population (10-49%) slow but significant deterioration medium

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
