Black Wallaroo
Osphranter bernardus · also called black wallaroos
Moving cautiously among the sandstone crevices of a remote Arnhem Land escarpment, a black wallaroo occupies one of the smallest and least studied ranges of any kangaroo family member, its dark coat blending easily into the shadowed rock it calls home.
Overview
The black wallaroo, Osphranter bernardus, is the smallest member of the wallaroo group, native exclusively to mountain and forest habitat within a restricted part of Arnhem Land in Australia’s Northern Territory. Its extremely limited range, distinctively dark coat, and status as one of the least studied members of the entire kangaroo family make it one of the more genuinely mysterious macropods found anywhere in Australia.
A wallaroo few have ever studied closely
Confined to a remote stretch of sandstone escarpment that has made detailed research difficult, the black wallaroo remains one of the more poorly understood large mammals in Australia, its small size and dark coat only adding to how easily it disappears into its rugged habitat.
Status
Near Threatened, owing to its naturally restricted range and limited available population data, despite no clear evidence of an active decline.
Black Wallaroo: common questions
How is the black wallaroo different from the common wallaroo?
This species is the smallest member of the wallaroo group, noticeably more compact than its larger relative the common wallaroo, with a notably dark coat, particularly in males, and a range restricted entirely to a small area of Arnhem Land rather than spread across much of mainland Australia.
Why is the black wallaroo considered Near Threatened?
This species has one of the most restricted ranges of any kangaroo family member, confined to a small, rugged stretch of sandstone escarpment, and this naturally small distribution combined with limited available data contributes to its classification as Near Threatened despite no clear evidence of an active population decline.
Why is so little known about the black wallaroo?
This species is considered one of the least studied members of the entire kangaroo family, largely due to its remote, rugged habitat in a restricted part of the Northern Territory that has made detailed population surveys and behavioural research genuinely difficult to conduct.
Where does the black wallaroo live?
This species is native exclusively to mountain and forest habitat within a restricted part of Arnhem Land in the Northern Territory, Australia, sheltering among rocky crevices and escarpment terrain found nowhere else within its tiny range.
