The Perch (grid reference ST480532) is a 72.1 hectare (178.2 acre) biological Site of Special Scientific Interest close to Cheddar Gorge in the Mendip Hills, Somerset, England.

The underlying rocks are almost entirely carboniferous limestone with a small amount of Triassic dolomitic conglomerate.

Two nationally rare plants, the Cheddar pink (Dianthus gratianopolitanus) and the Cheddar bedstraw (Galium fleurotii) are found on this site, as are two nationally scarce species: the rock stonecrop (Sedum forsterianum) and the spring cinquefoil (Potentilla tabernaemontani).

[1] This variety of habitats ensures that a wide range of fauna occurs on the site.

In total 22 species of mammal have been recorded including a strong population of dormouse (Muscardinus avellanarius) and five species of bat, including the Greater Horseshoe bat (Rhinolophus ferrumequinum) and Lesser Horseshoe bat (Rhinolophus hipposideros) which use the site for feeding.
