2011 high unfavourable medium
Was the whole site covered? Yes State assessed by Population
Accuracy of information good

Threats to the site (pressure)
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 happening now some of area/population (10-49%) slow but significant deterioration medium
Biological resource use fishing & harvesting aquatic resources - unintentional effects: subsistence/small scale happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Biological resource use gathering terrestrial plants - unintentional effects (species being assessed is not the target) happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Human intrusions and disturbance recreational activities happening now some of area/population (10-49%) slow but significant deterioration medium
Invasive and other problematic species and genes invasive non-native/alien species/diseases - unspecified species happening now majority/most of area/population (50-90%) moderate to rapid deterioration high

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
