Accuracy of information good

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Biological resource use logging & wood harvesting - intentional use: large scale happening now majority/most of area/population (50-90%) very rapid to severe deterioration very high

Condition of habitat (state)

Forest Mixed woodland 0 0 good (> 90%) good (> 90%) favourable

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
