Vegetation on the lower parts is mostly rainforest. In higher areas montane heath and grasstrees are found. The giant rock lily grows well on the slopes of Mount Cordeaux. The forest is mostly devoid of large red cedar, hoop pine, carabeen, pigeonberry, tulip oak or purple laurel, as Timber-getters in the early 1900s had harvested most of the area of Cunninghams Gap and Goomburra.
