Australia has two species of tree kangaroo, but another 15 species and subspecies – such as this Goodfellow’s tree kangaroo – are found across the Torres Strait in New Guinea. In the past, the species was threatened by habitat loss. Thank you for sharing. Before it lives independently, the joey is gradually weaned and spends some time outside of the pouch and some time in it. The Lumholtz's tree kangaroo is named after a Norwegian explorer and ethnographer named Carl Sofus Lumholtz (1851–1922). 13. They can be contact via email: treekangaroo.study@gmail.com or telephone 0499 180 961 Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.

Population & Health of Lumholtz's tree-kangaroo. 17. They are also threatened by oil drilling, logging, hunting by humans, and rainforest clearing. I find it interesting that the female kangaroo is usually ready for reproduction before the male. Marsupials are an important part of this diversity. The tenkile is still imperiled by deforestation, illegal logging and climate change. The Tenkile Conservation Alliance has improved conditions for both the critically endangered species and the local communities. Lumholtz spend four years in Queensland. Kangaroos, wallaroos, wallabies, and pademelons have a typical kangaroo appearance but different sizes. Linda Crampton (author) from British Columbia, Canada on December 27, 2018: Thanks for the interesting comment, Dora. In some areas, safe corridors between different patches of habitat exist.

The Lumholtz's tree kangaroo is the smallest member of the group, but I think they are all cute in some way. The Goodfellow’s tree-kangaroo is one of two priority Papua New Guinea tree-kangaroo species for which there are international cooperative breeding programmes. Most tree-kangaroo species are threatened or endangered due to hunting and deforestation. The woman in the second video, perhaps both, seem to be natural kangaroo lovers. The situation in Australia is very worrying. Population biology studies require that animals be followed over a long period in order to gather the information needed to be able to analyze what is going on with the population. Hunting moratoriums have been in place since 1999. However, there is a range in size between species. The last population assessment done by the IUCN was in 2014. The project is currently underway to learn more about the population of Lumholtz's tree-kangaroo and it health status. Sometimes wallabies or even possums can be mistaken for a tree kangaroo. A species that reaches 14kg, its Aboriginal name is tcharibeena. What diseases are present in the population? To establish whether the population is increasing or decreasing, we need to know the birth rate and mortality (survival) rate of the population. In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species.In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height.

Chitrangada Sharan from New Delhi, India on December 25, 2018: Excellent information about tree kangaroos. According to various reports, the Lumholtz's tree kangaroo is active during the day (diurnal), the night (nocturnal), or dusk and dawn (crepuscular). If you see a dead tree-kangaroo on the road: Once we get a report of a dead tree-kangaroo, we go to retrieve the carcass so a post-mortem examination (necropsy) can be performed and data collected. The scientific name of the Lumholtz's tree kangaroo is Dendrolagus lumholtzi. Figuring out the birth rate of a population involves learning about the reproductive biology of the animal. In Australia, although occasionally hunted by Aboriginal people, tree kangaroo populations - especially Lumholtz tree kangaroos - are threatened primarily by land clearing. However, if you refer to native Australian where the real Kangaroos are coming from, species such as the Red Kangaroo and Tree Kangaroo are mainly nocturnal whereas the Eastern and Western Grey Kangaroo are mainly diurnal. The loss of one population, perhaps due to a misinformed land-use decision, while bad enough, could become the loss of a previously unrecognised species.

Further research may change this assumption. © Terry Domico / WWF-Canon 4. I agree that it’s best to have genetic diversity and I hope that conservationists will seek ways to better the situation. It lives in a small area in Queensland to the north of the Lumholtz's tree kangaroo's habitat. A more accurate assessment of the animal's numbers would be useful. Though the animal travels through the trees with ease and spends most of its time there, it comes to the ground at times. I hope you have a happy new year and a great 2019.

The project aims to establish baseline medical information about the species, survey for infectious diseases, investigate what impact humans and their animals may be having on tree-kangaroos (and vice-versa) and investigate road and predator mortality with the hope that information gained may be useful in future management decisions about the species and in advising veterinarians and wildlife carers about typical injuries sustained from vehicles and predators with the aim of improving animal welfare and reducing suffering. Tree kangaroos play an important role in the culture and diet of the indigenous people, and unsustainable hunting practices threaten the survival of tree kangaroos. Linda Crampton (author) from British Columbia, Canada on December 21, 2018: Thank you for the comment, Pamela. It's also known as the boongary. 32.
