The Bottoms is a Site of Special Scientific Interest in County Durham, England. It lies just south of the A181 road, roughly midway between the Cassop and Wheatley Hill villages, some 10 km south-east of Durham city. The site's interest lies in unimproved magnesian limestone grassland, where blue moor-grass, Sesleria albicans, and small scabious, Scabiosa columbaria, are the dominant species. This is a scarce vegetation type found only in County Durham, and the extent of which has been severely reduced by quarrying and intensive agriculture. Other grasses that are frequent in the sward include meadow oat-grass, Avenula pratensis, quaking grass, Briza media, sheep's fescue, Festuca ovina, crested hairgrass, and Koeleria macrantha. There is a rich variety of herbs, including rock-rose, Helianthemum nummularium, glaucous sedge, Carex flacca, spring sedge, C. caryophyllea, and mouse-ear hawkweed, Pilosella officinarum, and a small population of purple milk-vetch, Astragalus danicus, a local rarity on magnesian limestone.

Wingate Quarry

Wingate Quarry is a biological Site of Special Scientific Interest in the County Durham district of east County Durham, England. Part of the site is also a Local Nature Reserve It is a disused quarry located just south of the village of Wheatley Hill. The quarry was worked for Magnesian Limestone until the 1930s, when it closed. Since then a large and varied grassland has developed on the site. Magnesian limestone grassland is nationally scarce, with this site accounting for close to 8 per cent of the national total. As well as species that are characteristic of this vegetation type, there are also two orchids, fragrant orchid, Gymnadenia conopsea, and frog orchid, Coeloglossum viride, both of which are uncommon in County Durham.
