National nature reserves in England were established by English Nature, now Natural England, which manages them either directly or through non-governmental organisations such as the Royal Society for the Protection of Birds or the National Trust.
Morecambe Bay is an estuary in northwest England, just to the south of the Lake District National Park. It is the largest expanse of intertidal mudflats and sand in the United Kingdom, covering a total area of 120 sq mi (310 km2). In 1974, the second largest gas field in the UK was discovered 25 mi (40 km) west of Blackpool, with original reserves of over 7 trillion cubic feet (tcf). At its peak, 15% of Britain's gas supply came from the bay but production is now in decline. Morecambe Bay is also an important wildlife site, with abundant birdlife and varied marine habitats.
Cardigan Island is an uninhabited island north of Cardigan, Ceredigion, south-west Wales. It reaches a height of 52 metres (171 ft) a.s.l., and 38 acres (15 ha) in area.
Furness is a peninsula and region of Cumbria, England. Together with the Cartmel Peninsula it forms North Lonsdale, historically an exclave of Lancashire. On 1 April 2023 it became part of the new unitary authority of Westmorland and Furness.
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. 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.
Gibraltar Point national nature reserve is an area of about 4.3 km2 (1.7 sq mi) on the coast of Lincolnshire, England.
The Duddon Estuary is the sandy, gritty estuary of the River Duddon that lies between Morecambe Bay and the North Lonsdale coast.
Walney Island, also known as the Isle of Walney, is an island off the west coast of England, at the western end of Morecambe Bay in the Irish Sea. Within the boundaries of the historic county of Lancashire, it is part of Barrow-in-Furness, separated from the mainland by Walney Channel, which is spanned by the Jubilee Bridge. Walney is the largest island of the Furness Islands group, both in population and size, as well as the largest English island in the Irish Sea. Its population at the 2011 UK Census was 10,651, distributed evenly across the island's two Wards of Walney North and Walney South.
Foulney Island is a low-lying grass and shingle area 1 mile (1.6 km) to the south-east of Roa Island, off the southern tip of the Furness Peninsula in Cumbria, England. Foulney Island is one of the Islands of Furness in Morecambe Bay, northern England. For local government purposes the island is in the borough of Barrow-in-Furness. It has an area of about 40 acres. In earlier times it was known as Fowle Island.
Cemlyn Bay is a bay on the northwest coast of Anglesey, North Wales, approximately 2.5 km west of Wylfa nuclear power station, within the community of Cylch-y-Garn.
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). An area of 4,395 hectares is also designated a Ramsar Wetland of International Importance, and a Special Protection Area 1,099 hectares is a National Nature Reserve. Tollesbury Wick and part of Abbotts Hall Farm, both nature reserve managed by the Essex Wildlife Trust, are in the SSSI.
Hodbarrow RSPB Reserve is a nature reserve run by the Royal Society for the Protection of Birds (RSPB) on the edge of the Lake District National Park in Cumbria, England. It is on the Duddon Estuary near the town of Millom and covers an area of 3.28 hectares.
Havergate Island is the only island in the county of Suffolk, England. It is found at the confluence of the River Ore and the Butley River near the village of Orford. It is a marshy nature reserve run by the Royal Society for the Protection of Birds (RSPB) and is known for its population of pied avocets and terns. It is part of the ecologically important Alde-Ore Estuary and has protected conservation status as part of a national nature reserve, SSSI, SAC, SPA, Ramsar Site and is also a part of the Suffolk Coast and Heaths AONB.
The flora and fauna of the Outer Hebrides in northwest Scotland comprises a unique and diverse ecosystem. A long archipelago, set on the eastern shores of the Atlantic Ocean, it attracts a wide variety of seabirds, and thanks to the Gulf Stream a climate more mild than might be expected at this latitude. Because it is on the Gulf Stream, it also occasionally gets exotic visitors.
The Western Rocks are a group of uninhabited skerries and rocks in the south–western part of the Isles of Scilly, United Kingdom, and are renowned for the numerous shipwrecks in the area and the nearby Bishop Rock lighthouse. In 1971, the rocks and islands were designated a Site of Special Scientific Interest for their breeding sea birds. Landing on the islands is both difficult and discouraged and there are few published records of visits by naturalists.
North Walney Nature Reserve is a national nature reserve on Walney Island, England. The reserve, which has an area of 646.5 ha, is notable as a habitat of natterjack toads. It is one of the sites in the Duddon Estuary which support one-fifth of the national population of the rare amphibian.
Sandscale Haws is a national nature reserve on the Duddon Estuary, Cumbria, England. It is managed by the National Trust. Resident species include the natterjack toad.
Roanhead refers to the limestone outcrop of Roanhead Crag in Cumbria and the farmland behind it, but in recent years the term has been taken to mean the sandy beaches adjoining Sandscale Haws extending to Snab Point. The Irish Sea lies to the west of Roanhead, whilst the Duddon Estuary and Walney Channel are due north and south respectively. The beach is noted for its abundance of sand dunes and strong, often dangerous coastal currents. Today the beach is a National Trust conservation area, and a two-mile stretch of the Cumbria Coastal Way runs through it.
The Norrard (Northern) Rocks are a group of small uninhabited granite rocks in the north–western part of the Isles of Scilly, to the west of Bryher and Samson. In 1971 they were designated as a Site of Special Scientific Interest (SSSI) for their breeding seabird colonies and they are permanently closed to landings from boat passengers. The vegetation on the islands is limited by the extreme exposure and only six species of flowering plants have been recorded.
Cumbria Coast is one of England's Marine Conservation Zones. It was designated in 2013 and is one of a number of such zones off the coast of Cumberland and Furness.
