[edit] Geological
St Dunstan's Well Catchment is an important and well-known cave system which includes a series of spectacularly-decorated caves which in total extend to about 4 miles of mapped passage. The caves were formed mainly by the erosive action of water flowing beneath the water-table at considerable pressure (so called 'phreatic' development), but as the water table has fallen many of the caves now lie well above it and the system now contains a variety of cave formations (stalagmites, stalactites and calcite curtains) which in their extent and preservation are unsurpassed in Britain. Shatter Cave and Withyhill Cave are generally considered to be the finest decorated caves in Britain in terms of their sheer abundance of pure white and translucent calcite deposits.
[edit] Biological
An area of nationally rare species-rich unimproved calcareous grassland of the Sheep's-fescue-Meadow Oat-grass type occurs in the field to the east of Stoke Lane Quarry. Small numbers of Greater Horseshoe Bat (Rhinolophus ferrumequinum), Lesser Horseshoe Bat (Rhinolophus hipposideros) and Natterer's bat (Myotis nattereri) hibernate in the cave system.<ref>St. Dunstan's Well Catchment.
