Doria’s tree kangaroo (Dendrolagus dorianus)

Species: Doria’s tree kangaroo (Dendrolagus dorianus)

Status: Vulnerable (VU)

Interesting Fact: Doria’s tree kangaroo is the heaviest tree-dwelling marsupial in the world, weighing as much as 20 kilograms, and is capable of jumping down to the ground from a height of up to 18 metres without injury.

Despite its appearance and arboreal nature, Doria’s tree kangaroo is closely related to the well-known ground kangaroos that can be seen across Australian plains, and has similar strongly developed hindquarters and a long, well-furred tail. Unlike its Australian relatives, Doria’s tree kangaroo is endemic to the island of New Guinea, where it is found in the central highlands. This species has fairly long fur, which interestingly grows in a reverse direction on the back and neck. This is presumably to stop water running down its face, as this marsupial tends to sit with its head lower than its shoulders.

While Doria’s tree kangaroo is thought to still be common in some areas of its range, intense and consistent hunting pressure for its meat has led to the local extinction of many populations of this species. In the past, hunting of this prized game species by local people may have been sustainable, but advances in the development of hunting equipment, combined with a rising human population, has led to an increase in hunting. Habitat loss and degradation of forested areas as a result of exploitation for timber poses an additional threat to Doria’s tree kangaroo.

Doria’s tree kangaroo is legally protected in the Indonesian part of New Guinea. However, this is not yet the case in Papua New Guinea, and the protection of vital forest habitat in this region has been recommended to ensure the future survival of this intriguing marsupial. In addition, measures to control or restrict traditional hunting have been suggested as key factors in the conservation of this threatened species.
