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 6,509.4-hectare (16,085-acre) biological Site of Special Scientific Interest which stretches from Sittingbourne to Whitstable in Kent. [1] [3] It is also a Ramsar internationally important wetland site [4] and a Special Protection Area under the European Union Directive on the Conservation of Wild Birds. [5] Parts of it are a Nature Conservation Review site, Grade I, [6] National Nature Reserves, [7] [8] [9] a Kent Wildlife Trust nature reserve [10] and a Local Nature Reserve. [11]
The name "Swale" is Old English in origin, and is believed to mean "swirling, rushing river", or "rushing water". [12]
At these times the Swale was a gully from what had been a sea channel in very warm periods. Namely before the Strait of Dover had swept away so much swampy land, accentuated by sea levels being lower, even to beyond the end of the ice age, i.e. in the mid seventh millennium BC, the coasts of Essex and Kent stretched much further into the North Sea. Sheppey formed part of mainland Britain. The Swale was a valley opening eastwards. As sea-levels rose again, water occupied its whole length. It and the very mouth of the Medway divide the Isle of Sheppey from the mainland.
When the Romans arrived in Britain, the Swale was much wider, with one part of the Isle of Sheppey — now called the Isle of Harty or Harty — a separate island.
Two c. 1600 to 1900 public ferries crossed the Swale. One operated between Oare and Harty, and the other between Murston (near Sittingbourne) and Elmley (another former hamlet and essentially attached islet). Harty is no longer separate but the marshlands gradually encroaching delineate it.
The channel needs constant dredging for busy recreational and light vessel use.
The Swale is crossed at its western end by two bridges: the Kingsferry Bridge and the later Sheppey Crossing.
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. [13]
The Swale provides habitats for the following birds:
The Isle of Sheppey is an island off the northern coast of Kent, England, neighbouring the Thames Estuary, centred 42 miles (68 km) from central London. It has an area of 36 square miles (93 km2). The island forms part of the local government district of Swale. Sheppey is derived from Old English Sceapig, meaning "Sheep Island".
Kent Wildlife Trust (KWT) is a conservation charity in the United Kingdom that was founded in 1958, previously known as the Kent Trust for Nature Conservation. It aims to "work with people to restore, save and improve our natural spaces" and to "ensure that 30% of Kent and Medway – land and sea – is managed to create a healthy place for wildlife to flourish". In 2023, they have reported over 30,000 members and an annual income of £8 million. KWT manages over ninety nature reserves in Kent, of which thirty-seven are Sites of Special Scientific Interest, three are national nature reserves, five are Special Areas of Conservation, four are Special Protection Areas, six are local nature reserves, thirty-eight are in Areas of Outstanding Natural Beauty and one is a scheduled monument.
The North Kent Marshes are in the far north of the county of Kent spanning dry and wet south banks and inlets of the Thames Estuary in south-east England. The marshes are one of 22 Environmentally Sensitive Areas recognised by the UK's Department for Environment, Food and Rural Affairs (DEFRA). They are in the Thames Gateway regional planning area. They include the 5,289-hectare (20.4 sq mi) South Thames Estuary and Marshes biological SSSI.
The Blackwater Estuary is the estuary of the River Blackwater between Maldon and West Mersea in Essex. It is a 5,538 hectare biological Site of Special Scientific Interest (SSSI).

Elmley is the local name for the Isle of Elmley, in the civil parish of Minster-on-Sea, part of the Isle of Sheppey in the Swale district, in the county of Kent, England. It was also the name of a very late 19th century industrial village on the isle. Edward Hasted describes, in 1798, the isle as two-eighths of the Isle of Sheppey estimated as 11 miles by 8 miles. Its present national nature reserve covers more than the easily traceable area of the former isle by extending to the east, over Windmill Creek, one of two Sheppey inlets, former internal tidal channels.
