In East Devon Area of Outstanding Natural Beauty. Part in County Structure Plan Coastal Preservation Area; Nature Conservation Zone; Mineral Consultation Area and Area of Mineral Working. Previously named Beer Stone Quarry and Bovey Lane Pit SSSI. Site boundary amended by deletion.
This site is important for its population of hibernating bats. Eight species are present some of which are very rare. There are also important geological features on the face of the working quarry.
The southern part of the site comprises an extensive series of caves which have been formed by many years of mining for Beer Stone. Regular recording began in 1951 and in recent years there have been approximately 70--80 individuals of an unusually wide range of bat species. These include the very rare Bechstein's bat Myotis bechsteini and the greater and lesser horseshoe bats Rhinolophus ferrumequinum and R. hipposideros. Other species present are Brandt's bat M. brandti, Daubenton's bat M. daubentoni, Natterer's bat M. nattereri, brown long-eared bat Plecotus auritus and whiskered bat M. mystacinus. The northern part of the site is an actively worked quarry and the old tunnels there are also used by bats.
Beer Quarry provides one of the best exposures of a suite of clay-filled chalk pipes in southern England. Such features are important for interpreting solutional processes operating in chalk landscapes but are rarely seen in section.
