The park has a variety of natural habitats and is important as a refuge area for the conservation of the native plants and animals of the district, including a number of threatened or geographically significant species.
The summit of Mount Imlay is of particular scientific interest because of its largely undisturbed nature, the presence of several threatened plant species and its biogeographical similarity to Tasmanian peaks.
The summit also has high natural landscape and recreational value. It is a distinctive and prominent peak in the Eden district and is a popular walking destination.
