Site details
Site description: A central area of mudflats and saltmarsh, and surrounding brackish marsh and pasture. The harbour itself has a narrow opening to the sea, flanked by shingle-beaches. The IBA supports large numbers of wintering wildfowl, and is also nationally important for wintering Phalacrocorax carbo.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Delineation rationale: First identified in 1989; no significant boundary changes since then. SPA boundary used from JNCC; digitised at 1:10,000 scale.
