IBA conservation assessment
Year of assessment	State	Pressure	Response
2015	near favourable	medium	low
Whole site assessed?	State assessed by	Accuracy of information
yes	habitat	medium

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	-	moderate (70-90%)	near favourable
Marine Neritic	-	good (> 90%)	favourable
Marine Coastal/Supratidal	-	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management plan exists but the management planning process has begun	Some limited conservation initiatives are in place	low
