The site was identified as important in 2000 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2000) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Barnacle Goose Branta leucopsis	358	358	individuals	100	favourable
Spotted Crake Porzana porzana	4	3	breeding pairs	75	near favourable

Dunlin Calidris alpina	11	1	breeding pairs	10	very unfavourable
Mediterranean Gull Larus melanocephalus	1	1	breeding pairs	100	favourable
Common Tern Sterna hirundo	57	2	breeding pairs	4	very unfavourable
