1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	majority/most of area/population (50-90%)	no or imperceptible deterioration	low
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	slow but significant deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Unknown	No management planning has taken place	Very little or no conservation action taking place	negligible

Habitat1	Habitat detail	% of IBA
Forest	Dry evergreen forest (tropical)	major (>10)
Artificial/Terrestrial	Arable land	minor (<10)
Grassland		-
Shrubland		-
