Together with nearby Innes National Park, it conserves a substantial proportion of the natural habitat remaining on southern Yorke Peninsula. The park comprises an area of undulating limestone plains and low, stabilised dunes that remain well vegetated with mallee and tea-tree scrub and some sheoak woodlands. It provides habitat for a number of threatened species including the nationally and state vulnerable Annual Candles, state rare Goldsack’s Leek-orchid (''Prasophyllum goldsackii''), and the nationally and state vulnerable Malleefowl and Western Whipbird (''Psophodes nigrogularis leucogaster'').〔
