The Waite Conservation Reserve in the Adelaide Hills face area, was dedicated to conservation and the furtherance of scientific knowledge in 1992. Today the Waite Conservation Reserve is noted as the largest, despite intermittent grazing over most of the 20th century. The Reserve remains the best surviving example of Grey Box Grassy Woodland. Home to hundreds of species of native plants as well as kangaroos, koalas and echidnas, it is a valuable asset to the University of Adelaide and the people of South Australia. The Reserve now comprises 147 hectares, of which 131 hectares are under Heritage Agreement. Magnificent remnant grey box trees and native understorey species are also to be found in the northwest section of The Waite Arboretum.
