The park is significant because of its biological, historic heritage, economic, recreational and educational values.
The park protects stands of lowland rainforest, an endangered ecological community, of both subtropical and dry rainforest forms, including a readily accessible area of dry rainforest, dominated by shatterwood (Backhousia sciadophora). It also protects areas of tall open eucalypt forest containing the endangered Craven grey box (Eucalyptus largeana), which is restricted to the local area. The park supports 17 threatened animal species.
Historic heritage values
The park protects the Mountain Maid Mine which is considered to be of potential state heritage significance for its history as an operating goldmine between 1876 and 1979, making it one of the longest continually operating goldmines in New South Wales.
The Mountain Maid precinct conserves and promotes an important tourist destination and school education facility. This and the park’s other recreation values help to support the Gloucester area’s local economy.
The park provides a range of recreational opportunities including heritage walks, tourist facilities, cycling and horse riding.
The history of goldmining and the presence of different vegetation communities in the park, from dry rainforest to dry sclerophyll, provide a unique and important educational resource for both school groups and the wider public.
