Checklists of Exmoor's Wildlife
In 1996 ENHS produced The Flora and Fauna of Exmoor National Park listing 8243 species which had been recorded. (Now out of print). Since then there have been a number of additions published annually in Exmoor Naturalist magazine. The following lists show what we have recorded so far and it is hoped there will be future updates.
