Cleland Conservation Park is a protected area located in the Adelaide Hills, South Australia about 22km south-east of the Adelaide city centre. Cleland Conservation Park conserves a significant area of natural bushland on the Adelaide Hills face and includes the internationally popular Cleland Wildlife Park and the popular tourist destinations of Mount Lofty summit and Waterfall Gully. It is maintained by the South Australian Department of Environment, Water and Natural Resources (DEWNR). The conservation park was named for Sir John Burton Cleland (1878-1971), a renowned naturalist, microbiologist, mycologist and ornithologist, and member of the Royal Society of South Australia. After a career in medicine and pathology, Cleland became keenly interested in wildlife conservation. The conservation park occupies land in the gazetted suburbs of Cleland, Crafers and Waterfall Gully. The conservation park is classified as an IUCN Category II protected area.
