Year of assessment (most recent) State (condition) Pressure (threat) Response (action)
2007 very unfavourable high low
Was the whole site assessed? State assessed by Accuracy of information
yes population medium

State (condition of the trigger species' populations)
Scientific name Common name Reference population Actual population Units % of population remaining Result
Gavia arctica Arctic Loon 15 5 breeding pairs 34 very unfavourable
Pandion haliaetus Osprey 10 5 breeding pairs 50 unfavourable
Haliaeetus albicilla White-tailed Sea-eagle 1 1 breeding pairs 100 favourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming likely in long term (beyond 4 years) some of area/population (10-49%) moderate to rapid deterioration medium
Energy production and mining renewable energy happening now whole area/population (>90%) slow but significant deterioration high
Human intrusions and disturbance recreational activities happening now majority/most of area/population (50-90%) moderate to rapid deterioration high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation action Result
Some of site covered (10-49%) A management plan exists but it is out of date or not comprehensive Some limited conservation initiatives are in place low
