Cadbury Hill is a designated Local Nature Reserve. In 2009, a 19th-century agricultural stock pond - previously hidden by undergrowth - was restored by the Yatton & Congresbury Wildlife Action Group (YACWAG). The Local Nature Reserve comprises ancient semi-natural woodland, scrub and unimproved grassland. Species of interest include marsh tit, noctule bat, slow worm, wood anemone, bluebell, betony, small scabious, rock rose, small leaved lime. On the northern limestone slope grow hundreds of common spotted orchids. The hill fort itself has many ant hills, which are visited by green woodpeckers.
