Was the whole site covered? Yes State assessed by Habitat
Accuracy of information -

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Climate change and severe weather drought happening now whole area/population (>90%) slow but significant deterioration high
Invasive and other problematic species and genes invasive non-native/alien species/diseases - named species happening now some of area/population (10-49%) slow but significant deterioration medium
Natural system modifications dams & water management/use - abstraction of surface water (agricultural use) happening now majority/most of area/population (50-90%) moderate to rapid deterioration high

Condition of habitat (state)
Habitat Habitat Detail Reference Area (ha) Actual Area (ha) % of habitat remaining % of carrying capacity (overall) Result
Wetlands (inland) 0 0 moderate (70-90%) moderate (70-90%) unfavourable

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
