The site was identified as important in 2011 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2011).
