2007 favourable very high medium
Was the whole site assessed? State assessed by Accuracy of information
yes population good

State (condition of the trigger species' populations)
Scientific name Common name Reference population Actual population Units % of population remaining Result
Hydrobates leucorhous 22 20 breeding pairs 91 favourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Climate change and severe weather habitat shifting and alteration happening now whole area/population (>90%) very rapid to severe deterioration very high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other 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 Not assessed medium
