Data Zone
The site was identified as important in 2001 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 (2001).
