Data Zone
The site was identified as internationally important for bird conservation in 2004 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 List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Red-breasted Goose Branta ruficollis | VU | winter (1995) | 90 birds | A1, B2 |
| Ferruginous Duck Aythya nyroca | NT | breeding (2000) | 20 pairs | A1 |
| Black Stork Ciconia nigra | LC | breeding (-) | 5–10 pairs | B2 |
| Pygmy Cormorant Microcarbo pygmaeus | LC | passage (2000) | 32 birds | A1 |
| Pygmy Cormorant Microcarbo pygmaeus | LC | winter (2002) | 224 birds | A1 |
| Whiskered Tern Chlidonias hybrida | LC | breeding (2000) | 45 pairs | B2 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2016) is shown below.
| IBA conservation assessment | |||

| Year of assessment | State | Pressure | Response |
| 2016 | poor | very high | medium |

|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Natural system modifications | likely in short term (<4 years) | whole of population/area (>90%) | rapid decline (>30% over 3 generations) | very high |
