Conservation actions taken at site (response)
Conservation Designation Management Planning Conservation Action Result
Most of site (50-90%) covered (including the most critical parts for important bird species) 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 medium
