Data Zone
The site was identified as important in 2014 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:| Species | Red List1 | Season | Year(s) | Size | IBA criteria |
|---|---|---|---|---|---|
| Black-billed Gull Larus bulleri | NT | breeding | 1969-2010 | 66-193 breeding pairs | A1 |
| Black-fronted Tern Chlidonias albostriatus | EN | breeding | 1970-1995 | 44-62 breeding pairs | A1, A4i |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2014) may differ.
