Site description This site covers two harbours joined by a stretch of water that separates Hayling Island from the mainland. Tidal channels drain the river basins and penetrate far inland. Habitats include extensive mudflats and associated saltmarshes, sand-dunes, islands, and areas of Juncus marsh and reedbed (Phragmites). The IBA is important for breeding terns and wintering and passage wildfowl and waders.
