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 |
---|---|---|---|---|
Smew Mergellus albellus | LC | breeding (1996) | 10–30 pairs | B2, C2 |
Wood Sandpiper Tringa glareola | LC | breeding (1996) | 20–40 pairs | C6 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2017) is shown below.

Whole area (>90%) covered by appropriate conservation designation | A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | high |
