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 ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Spotted Crake Porzana porzana | LC | breeding (1995–2003) | 6–35 males | C6 |
| Little Crake Zapornia parva | LC | breeding (1990–1998) | 50–60 males | C6 |
| Common Crane Grus grus | LC | passage (2009) | 1,500 birds | C2 |
| Black Tern Chlidonias niger | LC | breeding (1998) | 80 pairs | C6 |
| Bluethroat Luscinia svecica | LC | breeding (1995–2003) | 6–28 pairs | C6 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2008) is shown below.

| Natural system modifications | happening now | some of population/area (10–49%) | moderate decline (10–30% over 3 generations) | high |
| Human intrusions and disturbance | happening now | some of population/area (10–49%) | moderate decline (10–30% over 3 generations) | high |
| Agricultural expansion and intensification | likely in short term (<4 years) | some of population/area (10–49%) | rapid decline (>30% over 3 generations) | high |
