1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2002) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2002. The most recent assessment (2005) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Transportation and service corridors	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
