Thylogale billardierii (Desmarest, 1822), the Tasmanian pademelon, is a small macropodid now endemic to Tasmania; the other 5 species are on the Australian mainland or Papua, New Guinea. The body is compact with relatively long forelimbs compared with larger macropodids, short ears, and a tail two-thirds the head and body length that lies on the ground while at rest. The long pelage is dark brown above and yellow-to-rufous below. While running, its body lies more closely parallel to the ground than other macropodids. A browser more than a grazer, it occupies a wide range of habitats but is often associated with forest edges. Adults weigh 4–11 kg, and males are 50% heavier than females. At present, T. billardierii is secure, listed as “Least Concern”; it is threatened primarily by introduced carnivores.
