The western end of the Mendip Hills has, since 1972, been designated an Area of Outstanding Natural Beauty (AONB) under the National Parks and Access to the Countryside Act 1949. The Mendip Society, which was formed in 1965, helps to raise awareness of this designation and protect the area. The society now has 700 members and runs a programme of guided walks and educational presentations. The society also has a small grants fund to assist communities with the conservation and enhancement of the landscape and to encourage its enjoyment and celebration.
