List of local nature reserves in Cambridgeshire

Cambridgeshire (abbreviated Cambs.) is a ceremonial county in the East of England and East Anglia. It is bordered by Lincolnshire to the north, Norfolk to the north-east, Suffolk to the east, Essex and Hertfordshire to the south, and Bedfordshire and Northamptonshire to the west. The largest settlement is the city of Peterborough, and the city of Cambridge is the county town. The county has an area of 3,389 km2 (1,309 sq mi) and a population of 852,523. Peterborough (179,349) and Cambridge (145,674), located in the north-west and south respectively, are by far the largest settlements. The remainder of the county is rural, and contains the city of Ely (20,112) and towns such as Wisbech and St Neots. Cambridgeshire contains six local government districts; five are part of a two-tier non-metropolitan county also called Cambridgeshire, and the district of Peterborough is a unitary area. The local authorities collaborate through Cambridgeshire and Peterbrough Combined Authority. The county did not historically include Huntingdonshire or the Soke of Peterborough, which was part of Northamptonshire. The north and east of the county are dominated by the Fens, an extremely flat, drained marsh maintained by drainage ditches and dykes. Holme Fen is the UK's lowest physical point, at 2.75 m (9 ft) below sea level. The flatness of the landscape makes the few areas of higher ground, such as that Ely is built on, very conspicuous. The landscape in the south and west is gently undulating. Cambridgeshire's principal rivers are the Nene, which flows through the north of the county and is canalised east of Peterborough; the Great Ouse, which flows from west to east past Huntingdon and Ely; and the Cam, a tributary of the Great Ouse which flows through Cambridge.

Cambridgeshire is a county in eastern England, with an area of 339,746 hectares (1,312 sq mi) and a population as of mid-2015 of 841,218. It is crossed by the Nene and the Great Ouse rivers. The University of Cambridge, which was founded in the thirteenth century, made the county one of the country's most important intellectual centres. A large part of the county is in The Fens, and drainage of this habitat, which probably commenced in the Roman period and was largely completed by the seventeenth century, considerably increased the area available for agriculture.The administrative county was formed in 1974, incorporating most of the historic county of Huntingdonshire. Local government is divided between Cambridgeshire County Council and Peterborough City Council, which is a separate unitary authority. Under the county council, there are five district councils, Cambridge City Council, South Cambridgeshire District Council, East Cambridgeshire District Council, Huntingdonshire District Council and Fenland District Council.In England, Sites of Special Scientific Interest (SSSIs) are designated by Natural England, which is responsible for protecting England's natural environment. Designation as an SSSI gives legal protection to the most important wildlife and geological sites. As of March 2017, there are 99 sites designated in the county. There are eighty-eight sites listed for their biological interest, ten for their geological interest, and one for both interests. The largest site is Ouse Washes at 2,513.6 hectares (6,211 acres), which is partly in Norfolk. It is internationally important for its wintering and breeding waterfowl and waders, such as teal, pintail and wigeon. The smallest is Delph Bridge Drain at 0.1 hectares (0.25 acres), a short stretch of ditch which was designated because it was found to have a population of fen ragwort, which was believed to have been extinct in Britain since 1857. The only site designated for both biological and geological interests is Ely Pits and Meadows, which has nationally important numbers of bitterns, and has yielded sauropod dinosaurs and pliosaur marine reptiles dating to the Jurassic period.
