IBA Conservation

IBA conservation assessment
Year of assessment (most recent) State (condition) Pressure (threat) Response (action)
2018 very unfavourable very high medium
Was the whole site assessed? State assessed by Accuracy of information
yes habitat medium

State (condition of the trigger species' habitats)
Habitat Habitat detail Reference area (ha) Actual area (ha) Habitat quantity (% remaining) Habitat quality (carrying capacity) Result
Forest 243223 191295 - very poor (< 40%) very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Agricultural expansion and intensification annual & perennial non-timber crops - shifting agriculture happening now some of area/population (10-49%) moderate to rapid deterioration high
Biological resource use hunting & collecting terrestrial animals - unintentional effects (species is not the target) happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Energy production and mining mining and quarrying happening now majority/most of area/population (50-90%) very rapid to severe deterioration very high
Human intrusions and disturbance work and other activities happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Transportation and service corridors roads and railroads happening now some of area/population (10-49%) slow but significant deterioration medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation action Result
Most of site (50-90%) covered (including the most critical parts for important bird species) A management plan exists but it is out of date or not comprehensive Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
