National nature reserves in England are designated by Natural England as key places for wildlife and natural features in England. They were established to protect the most significant areas of habitat and of geological formations. NNRs are managed on behalf of the nation, many by Natural England itself, but also by non-governmental organisations, including the members of The Wildlife Trusts partnership, the National Trust, and the Royal Society for the Protection of Birds.
Teesdale is a dale, or valley, located principally in County Durham, North East England. It is one of the Durham Dales, which are themselves part of the North Pennines, the northernmost part of the Pennine uplands.
Whitbarrow is a hill in Cumbria, England, designated a biological Site of Special Scientific Interest and national nature reserve, forming part of the Morecambe Bay Pavements Special Area of Conservation due to its supporting some of the best European examples of natural limestone habitats. Also known as Whitbarrow Scar, the hill lies about 9 kilometres (5.6 mi) southwest of Kendal, just north of the A590 road, close to the village of Witherslack. Part of the site is a local nature reserve called Whitbarrow Scar. Whitbarrow's summit, known as Lord's Seat, is at 215 metres (705 ft) and has a prominence of 182 metres (597 ft), classifying it as a Marilyn.
The Cotswold Water Park is the United Kingdom's largest marl lake system, straddling the Wiltshire–Gloucestershire border, north-west of Cricklade and south of Cirencester. There are 180 lakes, spread over 42 square miles (110 km2).
Upper Teesdale is a Site of Special Scientific Interest (SSSI) in the west County Durham, England. It encompasses an extensive upland area that includes the headwaters of the River Tees and the surrounding catchment area upstream of the village of Langdon Beck.
Moorhouse and Cross Fell is a Site of Special Scientific Interest covering an extensive area of moorland in the Wear Valley district of west County Durham and the Eden district of Cumbria, England. It is contiguous with Upper Teesdale SSSI to the east and Appleby Fells SSSI to the south. The area covered extends roughly from an arc through the villages of Gamblesby, Leadgate and Garrigill southward as far as Milburn in the west and Cow Green Reservoir in the east. It includes the whole of Cross Fell, the summit of which, at 893 metres asl, is the highest point in the Pennines and in England outside the Lake District.
Lune Forest is a Site of Special Scientific Interest covering an extensive area of moorland in the Teesdale district of west Durham, England. In the north, where it adjoins the Upper Teesdale and Appleby Fells SSSIs, it extends from Mickle Fell eastward almost as far as Harter Fell, above the hamlet of Thringarth. Its southern limit is marked by the River Balder, upstream from Balderhead Reservoir, where it shares a boundary with Cotherstone Moor SSSI to the south. Grains o' th' Beck Meadows and Close House Mine SSSIs are entirely surrounded by Lune Forest, but do not form part of it.
Red Moor is a nature reserve and Site of Special Scientific Interest (SSSI), noted for its biological characteristics, near Lanlivery in mid Cornwall, England, UK.
Allendale Moors is a Site of Special Scientific Interest (SSSI) in Northumberland, England. The upland moorland ridge site is listed for its heath, flush and upland grassland which provide a habitat for a nationally important assemblage of moorland breeding birds.
Quarry Moor is a Site of Special Scientific Interest, or SSSI, at the south edge of Ripon, North Yorkshire, England, and adjacent to the A61 road. It contains an outcrop of Magnesian Limestone, exposed by former quarrying. 255 million years ago this limestone was the peripheral sediment of a tropical sea. The land was donated in 1945 to the people of Ripon by the town's mayor, Alderman Thomas Fowler Spence, a varnish manufacturer. The land was notified as an SSSI in 1986 because its calcareous grassland supported a large diversity of plant species. The site features a Schedule 8 protected plant, thistle broomrape. The land is protected as a nature reserve, and it is also managed as a recreational area. Therefore, its calcareous grass area is fenced off for protection and study, but it also contains a car park, information signs, a children's play area, accessible paths, benches, and dog waste bins.
Mar Field Fen is a Site of Special Scientific Interest, or SSSI, north of Masham, North Yorkshire, England, in a rural area known as Marfield. It is situated on land containing woodland carr, fen, spring-fed marshy grassland and drier calcareous grassland, between the River Ure to the east and Marfield Wetland nature reserve to the west. As "one of the best examples of fen habitat in the Vale of York," it is a protected habitat for a variety of plants, including the common butterwort, a carnivorous plant. There is no public access to this site.
Ripon Parks is a Site of Special Scientific Interest, or SSSI, situated north of Ripon, to the west of the River Ure and to the east of the village of North Stainley, in North Yorkshire, England. It was once part of the land held since the Middle Ages as a deer park by the archbishops of York and the canons of Ripon. The site was designated as an SSSI in 1983, because its varied habitats are valued for their breeding birds, amphibians and varied flora. The woods here are "of note" for the parasitic flowers of common toothwort and yellow star-of-Bethlehem. A small part of the site is accessible via public footpaths; there are no public facilities or dedicated car parks. The site incorporates the High Batts Nature Reserve, which is privately run for training, recording and educational purposes, and accessible to members only, except for its annual open day. Ripon Parks is now owned by the Ministry of Defence, and parts of the site are used as military training areas.
