It protects the largest remnant forest and woodland in the central west region of the state, where interior and coastal New South Wales flora and fauna species overlap.

[1][2] Originally named Herveys Range by John Oxley in 1817, the area was reserved in 1897 as state forest because of its importance as a timber resource, and was designated a national park in 1995.

Eriostemon ericifolius is vulnerable based on TCS ACT 1995 and Astrotricha linearis only known record west of the Great Dividing Range.

Red ironbark (Eucalyptus fibrosa) in association with black cypress (Callitris endlicheri) shrubby woodland found on shallow sandy soils derived from sandstone.

[10] Weeds such as blackberry are significant as far as causing havoc within the natural environment forming large thickets blocking creeks suppressing native ground covers and providing a hiding spot for feral animals such as rabbits.

[3] Species that require specialized niches and or cannot disperse and effectively colonize suitable habitat will be affected if this current trend of human induced climate change continues.
