It is not known if this species occurs in any protected areas. Field surveys are needed to find this species. Although the area has not been well-sampled, there have been a few visits to the area with no reports of this species.
Known only from a single specimen (an adult male) collected in 1928 by Ernst Mayr in the Wondiwoi Peninsula of Papua (Indonesia). Elevation of specimen: 1,600 m asl.
The population of this species is unknown. The Tenkile Conservation Alliance estimates that if the species is still extant its population is likely to be 50 or less (see http://www.tenkile.com/wondiwoi-tree-kangaroo.html). This is based on the very limited distribution of its likely habitat. It is quite possible that the species is extinct.
Presumably hunting is the main threat.
