Data Zone
The site was identified as internationally important for bird conservation in 2000 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 |
|---|---|---|---|---|
| Common Crane Grus grus | LC | breeding (1996) | 11–50 pairs | B2, C6 |
| Wood Sandpiper Tringa glareola | LC | breeding (1996) | 501–1,000 pairs | B2 |
| Short-eared Owl Asio flammeus | LC | breeding (1996) | 11–50 pairs | B2, C6 |
| Common Redstart Phoenicurus phoenicurus | LC | breeding (1996) | 501–1,000 pairs | B2 |
| Parrot Crossbill Loxia pytyopsittacus | LC | breeding (1996) | 51–100 pairs | B3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.
