Flagstaff Memorial Nature Reserve was bequeathed to the National Parks and Wildlife Service in 1968 by Mr H. C. Davidson who had planned to set the reserve aside as an experimental study area. Prior to that it was part of a wildlife refuge covering Mr Davidsonís property, which was called 'Flagstaff'.
Flagstaff Memorial Nature Reserve contains an endangered ecological community of white box, yellow box and Blakely's red gum woodland, which is listed under the Threatened Species Conservation Act 1995. It also contains a number of birds listed as vulnerable under the Threatened Species Conservation Act.
