Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Climate change and severe weather habitat shifting and alteration happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Human intrusions and disturbance recreational activities happening now some of area/population (10-49%) slow but significant deterioration medium
Human intrusions and disturbance work and other activities happening now small area/few individuals (<10%) no or imperceptible deterioration low
Invasive and other problematic species and genes problematic native species/diseases - unspecified species happening now 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
