Lumholtz's tree-kangaroo range |
Lumholtz's tree-kangaroo (Dendrolagus lumholtzi) is a rare, long-tailed marsupial found in rainforests in northeastern Australia. Like most tree-kangaroos (genus Dendrolagus), it lives alone in trees and feeds on plant matter. [2] It belongs to the macropod family (Macropodidae) with kangaroos, and carries its young in a pouch like other marsupials. It is threatened by climate change and diseases, and is found in the hilly, fertile Atherton Tableland near Cairns in north east Queensland.
The species name lumholtzi is after the Norwegian explorer Carl Sofus Lumholtz (1851–1922), [3] who was the first European to record a specimen in 1883. The local indigenous Dyirbal and Yidiny language name may have been either "mabi" or "mapi". [4]
It is the smallest of all tree-kangaroos, with males weighing an average of 7.2 kg (16 lbs) and females 5.9 kg (13 lbs). [5] Its head and body length ranges 480–650 mm (19–26 in), and its tail, 600–740 mm (24–29 in). [6] It has powerful limbs and has short, grizzled grey fur. Its muzzle, toes and tip of tail are black.
The Lumholtz's tree-kangaroos colonizes a variety of habitats, as long as they are flush with food and have stable and adaptable structural features. [7]
Lumholtz's tree-kangaroo are generally solitary animals, with the exception of male–female mating and the long, intimate mother–joey relationship. Each kangaroo maintains a "home range" and will be hostile towards a member of the same sex that enters it (the one exception seems to be non-hostile encounters between adult males and their male offspring). Thus, the male will protect his own range, and visit the ranges of the females in his group. Mating takes place in episodes of about twenty minutes, and is often quite aggressive.
The Lumholtz's tree-kangaroo is classified as near-threatened [2] by the IUCN, and authorities consider it as rare. [8] It was historically impacted by habitat loss through logging and land clearing. Currently, it is threatened by non-native diseases and by climate change, which causes temperature extremes and severe weather. [2]
In June 2019, it was reported that many Lumholtz's tree-kangaroos were going blind. Normally almost invisible in the treetops, they were being found in schools, sheds and in the middle of roads, unable to see and confused. Veterinarian Andrew Peters, from Charles Sturt University, said he had found evidence of optic nerve and brain damage, suggesting that a new viral infection was involved.[ citation needed ]
Karen Coombes, who has cared for injured tree kangaroos on her property west of Cairns for two decades, said she thought successive dry periods in the area were contributing to the eye problems. Her theory is that, because the animals only eat the leaves of the rainforest trees they inhabit, which are always fairly toxic, the drier-than-normal weather over recent years could have caused the toxins in the leaves to become more concentrated. [9] No toxin has been identified and this hypothesis remains speculative and unsubstantiated.
Other work by wildlife veterinarian Amy Shima and wildlife biologist Roger Martin (author of Tree-kangaroos of Australia and New Guinea), does not support these claims. Their fieldwork spanning five years has found no convincing evidence of widespread blindness in Lumholtz's tree-kangaroo. Working with a comparative veterinary ocular pathologist from a university in the United States, Shima has looked at nearly 100 eyes from Lumholtz's tree-kangaroo carcasses (primarily road-killed animals) and has found no evidence of widespread blindness or pathology. These findings were recently presented in a poster presentation at the international Wildlife Disease Association conference.[ citation needed ]
Tree-kangaroos are marsupials of the genus Dendrolagus, adapted for arboreal locomotion. They inhabit the tropical rainforests of New Guinea and far northeastern Queensland, along with some of the islands in the region. All tree-kangaroos are considered threatened due to hunting and habitat destruction. They are the only true arboreal macropods.
Macropodidae is a family of marsupials that includes kangaroos, wallabies, tree-kangaroos, wallaroos, pademelons, quokkas, and several other groups. These genera are allied to the suborder Macropodiformes, containing other macropods, and are native to the Australian continent, New Guinea and nearby islands.
The squirrel glider is a nocturnal gliding possum. The squirrel glider is one of the wrist-winged gliders of the genus Petaurus.
The tiger quoll, also known as the spotted-tail quoll, the spotted quoll, the spotted-tail dasyure, native cat or the tiger cat, is a carnivorous marsupial of the quoll genus Dasyurus native to Australia. With males and females weighing around 3.5 and 1.8 kg, respectively, it is the world's second-largest extant carnivorous marsupial, behind the Tasmanian devil. Two subspecies are recognised; the nominate is found in wet forests of southeastern Australia and Tasmania, and a northern subspecies, D. m. gracilis, is found in a small area of northern Queensland and is endangered.
The bridled nail-tail wallaby, also known as the bridled nail-tailed wallaby, bridled nailtail wallaby, bridled wallaby, merrin, and flashjack, is a vulnerable species of macropod. It is a small wallaby found in three isolated areas in Queensland, Australia, and whose population is declining. In early 2019 the total population of the species was estimated to be fewer than 500 mature individuals in the wild and 2285 in captivity.
The dingiso, also known as the bondegezou or bakaga, is an endangered, long-tailed marsupial found only in mountain forests on the west of the island of New Guinea. It is a species of tree-kangaroo, which are mammals native to Australia and New Guinea that feed on leaves or other plant matter. It belongs to the macropodid family (Macropodidae) with kangaroos, and carries its young in a pouch like most other marsupials. Though sacred to the local Moni people, it is still threatened by hunting and habitat loss.
Matschie's tree-kangaroo, also known as the Huon tree-kangaroo is a tree-kangaroo native to the Huon Peninsula of northeastern New Guinea island, within the nation of Papua New Guinea. Under the IUCN classification, Matschie's tree-kangaroo is an endangered species. The scientific name honours German biologist Paul Matschie. The indigenous population refers to it as a Boongarry.
The long-nosed potoroo is a small, hopping mammal native to forests and shrubland of southeastern Australia and Tasmania. A member of the potoroo and bettong family (Potoroidae), it lives alone and digs at night for fungi, roots, or small insects. It is also a marsupial and carries its young in a pouch. The long-nosed potoroo is threatened by habitat loss and introduced species such as cats or foxes. There are two subspecies: P. t. tridactylus on mainland Australia, and P. t. apicalis on Tasmania, with lighter fur.

Goodfellow's tree-kangaroo, also called the ornate tree-kangaroo, is an endangered, long-tailed mammal native to rainforests of New Guinea. Like most tree-kangaroos, it lives in the treetops and feeds on leaves or other plant matter. It belongs to the macropod family (Macropodidae) along with kangaroos, and carries its young in a pouch like other marsupials. Its main threats are habitat loss and hunting. There are two subspecies: D. g. goodfellowi and D. g. buergersi.
Bennett's tree-kangaroo is a large tree-kangaroo. Males can weigh from 11.5 kg up to almost 14 kg, while the females range between about 8 to 10.6 kg. They are very agile and are able to leap 9 metres (30 ft) down to another branch and have been known to drop as far as 18 metres (59 ft) to the ground without injury.
The golden-mantled tree-kangaroo is a critically endangered, furry, bear-like mammal found only in mountain rain forests on the island of New Guinea. Like other tree-kangaroos, it lives in trees and feeds on plant matter. It belongs to the macropod family (Macropodidae) with kangaroos, and carries its young in a pouch like other marsupials. The range is restricted to two small mountain areas in the north and it is threatened by hunting and habitat loss.
The red-legged pademelon is a species of small macropod found on the northeastern coast of Australia and in New Guinea. In Australia it has a scattered distribution from the tip of Cape York Peninsula in Queensland to around Tamworth in New South Wales. In New Guinea it is found in south central lowlands.
Doria's tree-kangaroo is a long-tailed, furry, bear-like mammal found only in tropical mountain forests on the island of New Guinea. It is one of the largest tree-kangaroos, living alone in trees and active at night to feed on leaves or fruit. It belongs to the macropod family (Macropodidae) with kangaroos, and carries its young in a pouch like other marsupials. Threats include hunting and habitat loss.
The grizzled tree-kangaroo is a furry, long-tailed mammal native to tropical rainforests on the island of New Guinea. Like most tree-kangaroos, it lives in trees and eats leaves, fruit, and bark. It is a member of the macropod family Macropodidae and carries its young in a pouch like other marsupials. The tree-kangaroo is uncommon and threatened by hunting and habitat loss. It is found in foothill forests of northern and western New Guinea and is indigenous to some of the offshore islands.
The lowlands tree-kangaroo, also spelt "lowland," is a long-tailed, furry, bear-like mammal found only in lowland tropical rainforests on the island of New Guinea. It is a species of tree-kangaroo, which are tree-dwelling animals that feed on leaves or other plant matter. Tree-kangaroos are in the macropod family (Macropodidae) with kangaroos, and like other marsupials they carry their young in a pouch. The lowlands tree-kangaroo is threatened by habitat loss.
The ursine tree-kangaroo is a long-tailed, furry, bear-like mammal found only in tropical forests on the island of New Guinea. Slightly larger than a cat, it lives alone in trees and is active at night to feed on leaves and fruit. It belongs to the macropod family (Macropodidae) with kangaroos, and carries its young in a pouch like other marsupials. It has a small range in northwestern New Guinea and is threatened by habitat loss and hunting. Other common names for this species include the black tree-kangaroo, the Vogelkop tree-kangaroo and the white-throated tree-kangaroo.
