 The national park retains its ability to demonstrate the reasons for its natural and cultural significance, and the interplay between the values for which it was established.Scheyville National Park is of State heritage significance as it demonstrates a continuous history of significant use since pre-European settlement when the area supported the Dharug people with plentiful food supplies.The park also contains a number of historic features and places which demonstrate the early settlement of the Cumberland Plain, farming, defence and migrant uses of the area, and is significant as a relatively large surviving element of the first commons declared in the colony.
