Wildlife Sanctuaries were gazetted primarily to protect certain rare or endangered species in Sarawak and also serve as bank for various types of biodiversity.

The access to Wildlife Sanctuaries is strictly limited as a permit from the Chief Wildlife Warden is required for entry to the Sanctuaries.

Wildlife Rehabilitation Centres mainly house caged animals e.g. orang-utans, hornbills, porcupines etc. It is opened to the public and has been frequented by large numbers of local and foreign tourists.

Although tourism is not one of the centre's aims, visitors are encouraged as a way of promoting public awareness on Wildlife Conservations. Wildlife Centres also serve as an environmental education centre especially for school children, researchers and the public.
