Data Zone
The site was identified as internationally important for bird conservation in 2010 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.
Populations meeting IBA criteria ('key species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Common Little Bittern Ixobrychus minutus | LC | breeding (2000–2008) | 9–17 breeding pairs | C6 |
| Black-crowned Night Heron Nycticorax nycticorax | LC | breeding (2000–2008) | 137 breeding pairs | C6 |
| Purple Heron Ardea purpurea | LC | breeding (2004–2008) | 5 breeding pairs | C6 |
| Whiskered Tern Chlidonias hybrida | LC | breeding (2004–2008) | 145–460 breeding pairs | C6 |
| Black Tern Chlidonias niger | LC | breeding (2003–2008) | 25–70 breeding pairs | C6 |
| Common Tern Sterna hirundo | LC | breeding (2000–2008) | 95–380 breeding pairs | C6 |
| A4iii Species group - waterbirds | n/a | passage (2005–2008) | 20,000–40,000 individuals | C4 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2012) is shown below.
