Site details


Site description: The site covers the Humber estuary, and coastline to the north and south of the Humber mouth. It includes an elongated shingle-spit capped by sand-dunes (Spurn Point), extensive intertidal habitats (especially mudflats), saline lagoons and reedbeds (Phragmites). The IBA is important for breeding raptors and waders, and wintering/passage wildfowl and waders.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that meets the thresholds for at least one criterion described in the Global Standard for the Identification of KBAs.
Delineation rationale: First identified as two IBAs in 1989 (Humber Flats, Marshes and Coast; Tetney Marshes); combined into Humber Flats, Marshes and Coast in 1992; renamed to Humber Estuary in 2007. SPA boundary used from JNCC; digitised at 1:10,000 scale. Additional area added on 1:50,000 maps.
