Draycott Sleights supports extensive areas of traditionally managed species-rich unimproved calcareous grassland. Additional interest lies in a rich invertebrate fauna. The site is situated on steep south-west facing slopes of the Mendip Hills and ranges in altitude from to . 165 species of flowering plant have been recorded. The varied topography together with the widespread scrub provide a number of locations with ideal conditions for invertebrates supporting a rich butterfly fauna typical of unimproved calcareous grassland. 32 species of resident breeding butterfly have been recorded. The occurrence of Adonis blue (Lysandra bellargus), silver-studded blue (Plebejus argus) and small blue (Cupido minimus) is of particular interest. Two nationally scarce species of fly, Symphoromyia immaculata and Bombylius canescens and one nationally scarce species of ant, Myrmica schencki have been recorded for this site.
