Kemendok Nature Reserve was dedicated primarily to protect a remnant of river red gum/black box woodland and the endangered regent parrot which requires this habitat for its survival. It also contains old man saltbush shrublands, a community which is restricted in distribution and has been provisionally listed by the NSW Scientific Committee as an endangered ecological community in western NSW, and six threatened animal species.
The reserve also contains Aboriginal scarred trees and a number of interesting and locally significant historic sites.
