The Swale


The Swale is a tidal channel of the Thames estuary that separates the Isle of Sheppey from the rest of Kent. On its banks is a biological Site of Special Scientific Interest which stretches from Sittingbourne to Whitstable in Kent. It is also a Ramsar internationally important wetland site and a Special Protection Area under the European Union Directive on the Conservation of Wild Birds. Parts of it are a Nature Conservation Review site, Grade I, National Nature Reserves, a Kent Wildlife Trust nature reserve and a Local Nature Reserve.

History

The name "Swale" is Old English in origin, and is believed to mean "swirling, rushing river", or "rushing water".
The Swale was originally part of a river. Prior to the formation of the English Channel in about 6500 BC, the eastern coast of Great Britain extended much further into the area of the present-day North Sea, and the Isle of Sheppey formed part of mainland Britain. The channel now occupied by the Swale comprised a river valley facing eastwards. As sea-levels rose, water occupied the whole length of the valley, dividing today's Isle of Sheppey from the mainland.
When the Romans arrived in Britain, the Swale extended much wider than it does today, with one part of the Isle of Sheppey — now called the Isle of Harty — a separate island. Two ferry services also crossed the Swale, one between Oare and Harty, and the other between Murston and Elmley. The Isle of Harty is no longer separate but the marshlands now gradually filling the channel delineate it. The channel needs constant dredging to allow use of the busy waterway.
The Swale is crossed at its western end by two bridges: the Kingsferry Bridge and the later Sheppey Crossing.

Nature

The Swale forms both a National Nature Reserve and a Special Protection Area: the eel grass, Ray's knotgrass, white seakale, glassworts and golden samphire support rare and uncommon migrant butterflies and moths, including the Essex emerald, the ground lackey, the clouded yellow butterfly and rare hawk-moths.
Since 1968, it has also been a Site of Special Scientific Interest.
