Site description (baseline)
The Medway estuary forms a single tidal system with the Swale and joins the Thames estuary between the Isle of Grain and Sheerness. It has a complex arrangement of tidal channels, which drain around large islands of saltmarsh and grazing-marsh. The mudflats support extensive beds of algae and eel-grass Zostera. The IBA is important for wintering and passage wildfowl. Terns and gulls breed on saltmarsh islands, and wildfowl breed on the grazing-marshes.
