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 |
|---|---|---|---|---|
| Garganey Spatula querquedula | LC | non-breeding (2004) | present | A4i |
| Little Cormorant Microcarbo niger | LC | resident (2004) | present | A4i |
| Whiskered Tern Chlidonias hybrida | LC | non-breeding (2004) | present | A4i |
| A4iii Species group - waterbirds | n/a | unknown (2004) | min 20,000 birds | A4iii |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2003) is shown below.
