IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2011) is shown below.

Year of assessment State Pressure Response
2011 favourable very high low
Whole site assessed? State assessed by Accuracy of information

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Forest good (> 90%) good (> 90%) favourable

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Natural system modifications happening now majority/most of area/population (50-90%) very rapid to severe deterioration very high
Agricultural expansion and intensification happening now majority/most of area/population (50-90%) slow but significant deterioration high
Transportation and service corridors happening now some of area/population (10-49%) slow but significant deterioration medium
Energy production and mining likely in long term (beyond 4 years) some of area/population (10-49%) slow but significant deterioration medium
Biological resource use 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 areas Management plan Other 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site (50-90%) covered (including the most critical parts for important bird species) A management plan exists but it is out of date or not comprehensive Some limited conservation initiatives are in place low
