The site was identified as important in 2004 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):
Species Current IUCN Red List Category Season Year(s) Population estimate at site IBA criteria met
Black-faced Spoonbill Platalea minor EN winter 2003 present A1, A4i
Whimbrel Numenius phaeopus LC passage 2003 present A4i
Red-necked Stint Calidris ruficollis NT passage 2003 present A4i
Dunlin Calidris alpina LC winter 2003 present A4i
Terek Sandpiper Xenus cinereus LC passage 2003 present A4i

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation action Result
Little/none of site covered (<10%) A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species Some limited conservation initiatives are in place low
