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
Biological resource use hunting & collecting terrestrial animals - unintentional effects (species is not the target) happening now small area/few individuals (<10%) very rapid to severe deterioration low
Human intrusions and disturbance recreational 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 - named species happening now some of area/population (10-49%) very rapid to severe deterioration 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
