Was the whole site covered? Yes State assessed by Population
Accuracy of information good

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) some of area/population (10-49%) moderate to rapid deterioration medium
Human intrusions and disturbance work and other activities past (and unlikely to return) and no longer limiting some of area/population (10-49%) no or imperceptible deterioration low
Invasive and other problematic species and genes problematic native species/diseases - named species happening now majority/most of area/population (50-90%) very rapid to severe deterioration very high
Pollution agricultural & forestry effluents - nutrient loads happening now small area/few individuals (<10%) slow but significant deterioration low
Pollution domestic & urban waste water - sewage happening now small area/few individuals (<10%) slow but significant deterioration low
Transportation and service corridors shipping lanes likely in short term (within 4 years) small area/few individuals (<10%) moderate to rapid deterioration low

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
