Marsupials thought extinct for 6,000 years found in West Papua

In an astonishing discovery, two marsupial species believed to be extinct for 6,000 years have been rediscovered alive and well in the remote rainforests of West Papua. The pygmy long-fingered possum and the ring-tailed glider were located with the crucial assistance of local indigenous Vogelkop clans. However, their survival remains precarious as their habitats are increasingly threatened by logging and the expansion of the palm oil colonialism in West Papua. Laws and native title to protect this region is essential for indigenous land defenders. We musn’t let them disappear again #BoycottPalmOil #Boycott4Wildlife

Two extraordinarily rare marsupials, entirely believed to have been extinct for over six thousand years, have been discovered alive in the remote, Vogelkop mountain forests of the Bird’s Head peninsula in West Papua. This remarkable rediscovery of the pygmy long-fingered possum and the ring-tailed glider was confirmed by Australian scientist Professor Tim Flannery, alongside a team of local indigenous experts and university researchers.

“More important than finding a living thylacine in Tasmania.”

Scott Hucknull from Central Queensland University describes the magnitude of the discovery.

These species are rare examples of “Lazarus taxa”. Animals who disappear from the fossil record only to be found alive centuries later. Flannery noted that the likelihood of finding even one lost mammal was almost zero, let alone two.

“It’s unprecedented and groundbreaking, really, to find two Lazarus taxa,” Flannery says. “We’ve been able to finalise two pieces of work that are incredibly important from a biological and a conservation perspective, documenting the existence of rare marsupials in an area under threat. It’s sort of a crowning glory in my career as a biologist.”

The first of the resurrected species is the pygmy long-fingered possum, Dactylonax kambuayai. This tiny, striped marsupial possesses an extraordinary evolutionary trait: an elongated fourth finger on each hand that is double the length of other digits. Flannery explains that they use this finger to extract grubs from timber.

“They’ve got a whole lot of specialisations in their ear region as well, which seem to be related to detection of low-frequency sound. So presumably they’re listening for wood-boring beetle larvae, and they then rip open the rotting wood and use that finger to fish out the grub,” Flannery says.

The second species, the ring-tailed glider (Tous ayamaruensis), features unfurred ears and a strong, prehensile tail used for gripping branches. Flannery calls it “one of the most photogenic animals, most beautiful marsupials you’ll ever see.”

Crucially, the rediscovery of these elusive creatures was entirely dependent on the profound ecological knowledge of the local Tambrauw and Maybrat clans. These indigenous communities view the ring-tailed glider as deeply sacred, believing them to be manifestations of their ancestors’ spirits, and actively protect them from hunting. Rika Korain, a Maybrat woman and co-author of the research, emphasised that identifying the species relied entirely on traditional owners. “This connection has been essential,” she says.

“I’m very proud that Papuan researchers contributed to these landmark discoveries, and want to thank the people of the Misool, Maybrat and Tambrouw regions who supported us in the field,”

Dr Aksamina Yohanita of the University of Papua said.

“The Vogelkop is an ancient piece of the Australian continent that has become incorporated into the island of New Guinea. Its forests may shelter yet more hidden relics of a past Australia,”

Tim Flannery

To protect the remaining populations from the illegal wildlife trade, researchers are keeping their exact locations highly classified. Flannery delivered a stark warning to potential poachers regarding the animals’ survival in captivity: “They would be incredibly difficult to keep in captivity. because their diet is so highly specialised. Advanced warning for anyone who’s thinking of keeping one as a pet: it won’t live long,” he says.

While their rediscovery is a triumph, their future is highly uncertain. The proximity of power-hungry corporates intent on razing the rainforest for palm oil and timber casts a dark shadow over the region.

David Lindenmayer, an ecologist at the Australian National University, who was not involved in the study said “I am also hugely concerned about the extent of logging and land clearing happening in New Guinea,” he says. “It also makes me wonder what might have been lost in Australia as a result of all of the land clearing that has taken place here.”

The findings underline strong calls from scientists, environmentalists and indigenous rights advocates for Native Title legal land rights and indigenous-led protections of West Papua and its imperilled Vogelkop rainforest where these delightful marsupials are found.

Encountering the World’s Most Endangered Kangaroo: The Wondiwoi Tree Kangaroo

Encountering the Wondiwoi tree kangaroo, the world’s most endangered kangaroo, in West Papua’s lush forests is a bittersweet tale. Rediscovered in 2018 by British botanist Michael Smith, this rarest kangaroo, with soulful eyes and burnt umber fur, symbolises tranquillity amidst severe threats like palm oil deforestation and hunting. Less than 50 kangaroos remain alive, underscoring the urgent need for conservation efforts prioritising indigenous sovereignty. To help save these remarkable creatures, join the #Boycottpalmoil and #Boycott4Wildlife and take action via this website.

A Bittersweet Rediscovery of the Rarest Kangaroo Alive

In the dense, emerald heart of the Wondiwoi Mountains, in West Papua the trees echo with the haunting refrains of the vogelkop superb bird-of-paradise. Underfoot, the ground is soggy and dense with mossy herbaceous fragrances and the scuttling of an eastern long-beaked echidna as she burrows into her subterranean domain. In 2018, an extraordinary moment was captured forever on camera in 2018. High in the treetops, amidst the thick moss-covered branches, a shy Wondiwoi tree kangaroo lay in quiet repose, a symbol of sturdy, plump beauty. This creature was believed to be extinct for nearly a century. Yet a chance encounter by British amateur botanist Michael Smith in 2018 has thrust this creature back into the spotlight.

Wondiwoi tree kangaroos Dendrolagus mayri have an odd combination of kangaroo and monkey qualities. Large and soulful eyes blink from behind long eyelashes and thickly furred paddle-like arms culminate in strong sharp claws fit for grasping tree branches. Their bodies are the colour of burnt umber and terracotta and embody the tranquillity of Papua’s majestic montane forests where they blend into the painter’s palette of the jungle.

Smith’s serendipitous discovery of Wondiwoi tree kangaroos, known as the world’s rarest and most endangered kangaroo, highlights their precarious existence due to human-related threats like palm oil deforestation, rare mineral mining and hunting throughout their range.

A Journey Fuelled by Passion and Curiosity

Michael Smith is an amateur botanist from England. He spends a lot of his free time traversing remote locations like Indonesia, Pakistan and Kurdistan in the faint hope of encountering the rarest species on earth.

“I want these animals to be the poster children for seriously threatened and ancient habitats. I’m trying to get evidence of something interesting – and in terms of getting people involved and excited about conservation, it seems to be effective.”

Michael Smith, interview in the Guardian, 2023.

He understands that time is of the essence to save these animals and many others from the relentless growth of palm oil deforestation.

It’s hard to know if things will change fast enough for there to be anything left. In the 1990s, Papua New Guinea was just a big forest, with a few people. Now it’s still 80% or 90% forest, but there is huge pressure from people and investors who want to make palm oil.” 

Michael Smith, interview in the Guardian, 2023.

The Enigmatic Wondiwoi Tree Kangaroo

The bittersweet rediscovery of the Wondiwoi tree kangaroo underscores their gravely precarious position as the rarest kangaroo in the world. Originally they were discovered in 1928 by Ernst Mayer and known only by a single specimen. Papuan non-profit Tenkile Conservation Alliance estimates that less than 50 individuals remain alive.

The Wondiwoi tree kangaroo’s habitat is under severe threat from palm oil deforestation and the extraction of rare minerals such as mica and gold. The forests of West Papua, once a haven for diverse wildlife, are being decimated in silence.

The Guardians of the Forest

The survival of the Wondiwoi tree kangaroo is intricately linked to the sovereignty, and land stewardship of the Papuan indigenous peoples. Their deep spiritual and ancestral connection to the land and its human and more-than-human inhabitants stands in stark contrast to the destructive policies of the colonialist Indonesian government. Conservation efforts must prioritise indigenous rights and knowledge, recognising that true protection of these animals lies in the hands of those who have lived in harmony with the forest for many millennia.

Tenkile Conservation Alliance have a range of programmes helping indigenous peoples to understand the importance of conserving rather than hunting tree kangaroos and providing them with ways to harvest alternative sources of food. They have developed tree kangaroo hunting moratoriums as well alongside village communities.

The Jungle Kingdom of Dendrolagus: Tree Kangaroos

The genus Dendrolagus, more enchantingly known as tree kangaroos, embody arboreal grace and irresistible chubby cuteness. These marsupials are lesser known than their iconic ground-dwelling cousins further south in Australia and possess a range of distinctive traits making them masters of the jungle canopy.

Their exceptionally long, pendulous tails act as elegant counterbalances, helping with every leap and bound. Strong forelimbs, paired with shorter and broader hind feet, provide them with superior strength and agility. Long curved claws and spongy paws enhance grip, like natural bouldering shoes, allowing them to climb and cling effortlessly to branches.

Females possess a forward-opening pouch (marsupium) containing four teats. These provide a nurturing haven for their developing young. Their teeth are adapted for shearing leaves, reveal their dietary preference for the verdant foliage of the treetops.

Taking Action: How You Can Help

The rediscovery of the Wondiwoi tree kangaroo underscores the urgent need for consumer action. Here’s how you can make a difference:

1. Boycott Palm Oil: Reject RSPO greenwashing and avoid products containing “sustainable” palm oil. Use your purchasing power to demand palm oil free in the supermarket. Join the #Boycottpalmoil and #Boycott4Wildlife movement on social media.
2. Raise Awareness: Share posts on social media and engage in supermarket sleuthing to expose brands that use palm oil. Highlight the ongoing deforestation and animal cruelty.
3. Support Indigenous Sovereignty: Advocate for the rights and sovereignty of Papuan indigenous peoples, recognising their crucial role in conserving rainforest habitats and as guardians of rare species.
4. Donate: Support the ongoing advocacy of Palm Oil Detectives and the non-profit Tenkile Conservation Alliance, who work tirelessly to protect indigenous peoples, endangered species and their environments.
5. Get Involved: Participate in local and global conservation efforts. Whether through social media activism, community education, or direct action, every effort counts.

By taking these steps, you can help ensure that the Wondiwoi tree kangaroo and other endangered species in Papua have a fighting chance to survive and thrive.

The fight to protect the Wondiwoi tree kangaroo is a testament to the resilience of nature and the enduring spirit of people all over the world who strive to safeguard it. Together, we can shine a light on the darkness of deforestation and exploitation, ensuring a brighter future for these remarkable creatures and their forest home.

Behaviour & Appearance

Waigeo Cuscus, also known as the Waigeou Spotted Cuscus are cryptic and solitary marsupials of the family Phalangeridae. Not much is known about their ecology and behaviour and more research is needed in this area.

Waigeo Cuscus like other cuscus species have a strong prehensile tail that allows them to swing and hang in tree canopies.

Different cuscus species have eyes of varying colours. Waigeo Cuscuses have amber or orange eyes with have vertical pupils, similar to a cats or reptiles. This allows cuscuses to have superior night time vision. Like other cuscus, Waigeo Cuscuses have long nails to help with grip on tree branches and for grooming.

Geographical range

They are restricted to a small islet off the coast of the West Papua province called Waigeo Island. They prefer to live in primary or secondary tropical forests.

Threats

Their isolated and small geographic location makes their existence fragile and threatened by increased palm oil deforestation and mining in Waigeo Island, which is now taking place. An increase in hunting, mining and palm oil deforestation on the island would have a disastrous impact on this species.

Waigeo Cuscuses are classified as Vulnerable on IUCN Red List as they face many human-related threats including:

• Palm oil deforestation: Concessions for palm oil have been sold which invade into the Waigeo Cuscus’ range. They are limited to the small island and so any reduction in georgraphic range for palm oil will have disastrous consequences for them.
• Hunting and human persecution: These cuscus are hunted for their meat and fur.
• Mining: Mining concessions on Waigeo Island have been sold and this limits the geographic range of the Waigeo Cuscus across the small island.

Meet Chimbu, the blue-eyed, bear-eared tree kangaroo

Tree kangaroos are so unusual that when Europeans first encountered them in Australia in 1872, back on the continent they were sceptical if they were real! Who would believe a #kangaroo could climb a tree?

The Goodfellow’s tree kangaroo is an endangered species of the genus dendrolagus living in the Central Cordillera mountain ranges of Papua New Guinea. Help them to survive every time you shop and be #Vegan #BoycottPalmOil #Boycott4wildlife

A climbing kangaroo? That’s roo-diculous!

Europeans in New Guinea first described tree kangaroos in 1828. While there have been plenty of disagreements about who is related to whom, we now know there are 14 distinct species.

Early explorers considered the very idea of a climbing roo ridiculous, but these animals are specially adapted to life in the trees. They likely all evolved from a terrestrial ancestor earlier in the Pliocene, 5.3 million to 2.5 million years ago.

Tree kangaroos have much longer forelimbs than their ground-dwelling cousins and their claws are much larger and strongly curved. This provides much stronger grip when climbing trees and gripping smaller branches.

They still have large strong hind limbs, but their feet are shorter, broader and have a long curved claw on each toe.

The pad of the hindfoot is single, large and with prominent grooves, all of which enhance the animal’s grip when climbing and walking in the canopy. The tails of tree kangaroos aren’t capable of grasping things like a monkey’s, but they’re long and often held out behind the animal for balance.

But perhaps one of the most obvious differences between tree kangaroos and their terrestrial cousins is their adorably small bear-like ears.

Threatened with extinction

Two species of tree kangaroos are found in the forests of northeast Australia and 12 species in the jungles of New Guinea. All species of tree kangaroos are threatened with extinction in New Guinea, although much about these animals is unknown.

Traditionally hunted for food, hassled by dogs and threatened by the destruction of their forest habitat, the soft thud of tree roo feet among the trees is falling silent.

But conservation work in their natural habitat and through a globally managed tree kangaroo captive breeding program is helping not only the species, but the people who live alongside them.

Baby Chimbu – a new hope

Chimbu was born in Victoria, but is really an international fellow. His mother Mani came from the National Zoo and Aquarium in Canberra, and his father Bagam arriving from Kreffeld Zoo in Germany.

Mani and Bagam were paired based on the recommendation of scientists and managers who maintain a studbook of Goodfellow’s tree kangaroos around the world.

These gorgeous animals are generally chocolate brown on the back, shading to pale brown or cream on the face and belly, and often with a single or double narrow pale stripe down the back.

Their beautiful striped tails are one of their most noticeable features. And while the current population size is unknown, this tree kangaroo is thought to be declining due to hunting for food, local trading for cultural purposes, and habitat destruction through local deforestation and shifting cultivation.

Although the Goodfellow’s tree kangaroos are officially endangered, we don’t know much about them in the wild. Right now, the Wildlife Conservation Society is working out how many are in the wild and where, so scientists can develop a detailed conservation program.

Golden-mantled Tree Kangaroo Dendrolagus pulcherrimus

Golden-mantled Tree Kangaroo Dendrolagus pulcherrimus

Red List Status: Critically Endangered

Location: Papua New Guinea (Torricelli Range), West Papua (Foja Mountains)

In the misty cloud forests of New Guinea’s mountains, where ancient trees emerge from perpetual fog and birdsong echoes through emerald canopies, Golden-mantled Tree Kangaroos move with quiet grace through their vanishing world.

Golden-mantled Tree Kangaroos are one of the world’s rarest marsupials. Rarely glimpsed in the wild, their distinctive chestnut coats are adorned with golden stripes. These remarkable climbing kangaroos have suffered a catastrophic 90% population decline over three generations, leaving fewer than 500 individuals clinging on for survival in two remote mountain ranges. Palm oil expansion strips away their ancient forest homes while hunting pressure decimates remaining populations. The Tenkile Conservation Alliance protects the Torricelli population through community-based conservation, offering hope for recovery. #BoycottPalmOil #Boycott4Wildlife

Golden-mantled Tree #Kangaroos 🦘🤎 are critically endangered #marsupials of #PapuaNewGuinea 🇵🇬 They’re on the edge of #extinction from #palmoil #deforestation and #hunting. Resist for them and #Boycottpalmoil 🌴☠️🤮🙊⛔️ #Boycott4Wildlife @palmoildetect https://palmoildetectives.com/2021/01/26/golden-mantled-tree-kangaroo-dendrolagus-pulcherrimus/

Appearance and behaviour

The lowland areas of their distribution are earmarked for deforestation and oil palm expansion.

IUCN Red List

These resilient Tree Kangaroos display the physiological adaptations of arboreal marsupials with chestnut-brown coats, pale bellies, and distinctive double golden stripes running down their backs. Their yellowish necks, cheeks, and feet create a striking contrast against their darker fur, while their powerful tails marked with pale rings provide essential balance during canopy travel. These compact marsupials measure 40-77 centimetres in body length with tails reaching 40-87 centimetres.

Golden-mantled Tree Kangaroos possess powerful forelimbs and curved claws perfectly adapted for gripping bark and branches. Their shorter hind legs allow independent movement essential for navigating complex three-dimensional forest environments. Unlike ground kangaroos, these arboreal specialists can move both forwards and backwards along branches, using their long tails as fifth limbs for stability and balance.

Diet

Golden-mantled Tree Kangaroos are primarily folivorous, feeding on leaves from dozens of plant species found throughout their montane forest habitat. They supplement their diet with seasonal fruits, herbs, and sedges, spending considerable time foraging both in trees and on the forest floor. These selective feeders prefer young leaves and shoots from specific plant species, making them vulnerable when preferred food sources disappear.

Their feeding behaviour includes both arboreal and terrestrial foraging, with Golden-mantled Tree Kangaroos descending to ground level to access fallen fruits and herbs. This dietary flexibility has allowed them to persist in their restricted mountain habitats, though their dependence on specific plant species makes them particularly vulnerable to habitat conversion and fragmentation.

Reproduction and mating

Golden-mantled Tree Kangaroos reach sexual maturity at approximately two years of age with no defined breeding season. Females have an oestrous cycle estimated at 54 days with a gestation period of about 45 days. Once born, the tiny joey remains in the mother’s pouch for 10 months before emerging to spend another 2-3 months at foot, learning essential climbing and foraging skills.

These marsupials live relatively long lives, with captive individuals surviving over 14 years, suggesting wild Golden-mantled Tree Kangaroos could live 8-10 years under optimal conditions. Their extended dependency period reflects the complex skills required for arboreal survival, with mothers teaching joeys essential climbing techniques and food recognition during their extended care period.

Geographic Range

Golden-mantled Tree Kangaroos now survive in only two isolated mountain ranges across New Guinea. The Torricelli Range population in Papua New Guinea extends from Weight to Kuliek, while a smaller population persists in West Papua’s Foja Mountains. Fossil records indicate they once ranged across the Vogelkop Peninsula and other areas, but have been extirpated from 99% of their historical range.

Unconfirmed sightings from Papua New Guinea’s Prince Alexander Range suggest possible remnant populations, though these require verification. Their extremely restricted range of just 300 square kilometres makes Golden-mantled Tree Kangaroos particularly vulnerable to local extinctions from habitat loss, hunting, or natural disasters.

Threats

Industrial palm oil deforestation

Palm oil companies systematically bulldoze and burn Golden-mantled Tree Kangaroo habitat across West Papua, replacing mid-montane rainforests with lifeless monocultures. Korean company Korindo has destroyed 11,700 hectares of pristine rainforest in recent years, eliminating the complex canopy structure these arboreal marsupials require for survival. The company burns forests illegally, knowing this practice destroys critical habitat for tree kangaroos, birds of paradise, and cassowaries. Palm oil expansion has eliminated lowland portions of their range entirely, forcing Golden-mantled Tree Kangaroos into higher elevation refuges. Plantation development fragments the continuous forest cover essential for these territorial animals, creating isolated patches too small to support viable populations.

Hunting for bushmeat

Local communities hunt Golden-mantled Tree Kangaroos for subsistence protein, targeting them with guns during opportunistic forest expeditions. Hunting pressure intensifies near human settlements where access improves through road development and infrastructure expansion. The species’ small group sizes and territorial nature make them particularly vulnerable to hunting pressure, with entire local populations eliminated through intensive harvesting.

Infrastructure and road projects

Road construction opens previously inaccessible mountain areas to human exploitation, bringing hunting pressure and habitat disturbance into formerly secure territories. Small-scale agriculture eliminates forest understory vegetation while creating edge effects that degrade remaining habitat quality. The conversion of traditional forest management systems to intensive agriculture removes the ecological balance that historically supported both human communities and wildlife populations.

Take Action!

Use your wallet as a weapon and #BoycottPalmOil #Boycott4Wildlife every time you shop. Adopt a vegan lifestyle protecting both wild and farmed animals from agricultural expansion. Support the Tenkile Conservation Alliance’s community-based protection programmes recognising indigenous land rights. Refuse products containing palm oil, as this is driving Golden-mantled Tree Kangaroos towards extinction. #BoycottPalmOil #Boycott4Wildlife #Vegan

FAQs

How do Golden-mantled Tree Kangaroos climb trees?

Golden-mantled Tree Kangaroos have powerful forelimbs with curved claws that grip bark securely, while their shorter hind legs allow independent movement essential for navigating branches. They possess strong grips on their paws and foot soles providing non-slip traction when climbing. Their long tails act as fifth limbs, pressing against tree trunks for balance and stability during movement.

What do Golden-mantled Tree Kangaroos eat?

Golden-mantled Tree Kangaroos are primarily herbivorous, feeding on leaves from 91 known plant species, seasonal fruits, herbs, and sedges found in their montane forest habitat. They spend considerable time foraging both in trees and on the forest floor, preferring young leaves and shoots from specific plant species. Some sources suggest they occasionally consume young birds and bird eggs, though their diet consists predominantly of plant matter. Their selective feeding habits make them vulnerable when preferred food sources disappear due to habitat conversion or climate change.

How long do Golden-mantled Tree Kangaroos live?

In the wild, they typically live approximately 8-10 years, though current threats including hunting and habitat destruction may be reducing average lifespans. Captive individuals have survived over 14 years, suggesting they have potential for longer lifespans when protected from human pressures. Their generation length is approximately 10 years, indicating they reach reproductive maturity relatively late compared to smaller marsupials.

How big are Golden-mantled Tree Kangaroos?

Golden-mantled Tree Kangaroos measure 40-77 centimetres in body length with tails reaching 40-87 centimetres, making them substantially smaller than ground kangaroos. They weigh approximately 15.5 kilograms, a relatively light build essential for their arboreal lifestyle where they must be supported by tree branches. Both males and females are similar in size, showing less sexual dimorphism than many other kangaroo species.

Why are Golden-mantled Tree Kangaroos endangered?

Tragically, these tree kangaroos have experienced a catastrophic 90% population decline over three generations due to palm oil deforestation and hunting pressure. Palm oil companies have destroyed 99% of their historical habitat, replacing mid-montane rainforests with monoculture plantations offering no food or shelter. Hunting for bushmeat provides essential protein for local communities but removes breeding individuals from critically small populations. Their extremely restricted range of just 300 square kilometres makes them vulnerable to local extinctions, while habitat fragmentation prevents genetic exchange between isolated populations.

Can Golden-mantled Tree Kangaroos jump?

Golden-mantled Tree Kangaroos are capable jumpers, able to leap distances of up to 9 metres between trees and drop up to 18 metres to the forest floor without injury. They can climb heights equivalent to a 10-storey building, using their powerful hind legs and long tails for balance during aerial manoeuvres. Their jumping ability allows them to navigate between the treetops without descending to the dangerous ground level where predators pose greater threats. Their remarkable leaping capacity is essential for accessing food sources and escaping danger in their three-dimensional forest environment.

Tenkile Dendrolagus scottae

Tenkile Dendrolagus scottae

Location: Torricelli Mountains and Bewani Range, Papua New Guinea

IUCN Status: Critically Endangered

The #Tenkile, or Scott’s Tree #Kangaroo Dendrolagus scottae, is one of the most endangered #marsupials in the world, found only in the Torricelli Mountains and Bewani Range of #PapuaNewGuinea. These elusive tree kangaroos are unlike others of the #Dendrolagus genus as they spend a lot more time on the ground. These #treekangaroos were once widespread, but decades of hunting for food and deforestation for subsistence farming have driven them to the brink of extinction and they are now critically endangered. By the early 2000s, their population had plummeted to an estimated 100 individuals. However, the Tenkile Conservation Alliance (TCA) has led a community-driven conservation effort that has helped stabilise and even increase their numbers. Despite these successes, #timber and #palmoil expansion stills pose a major threat to this species’ survival. Resist and fight for their survival each time you shop—#BoycottPalmOil #Boycott4Wildlife.

#Tenkiles are unlike other #TreeKangaroos as they spend time on the ground leaving them at risk of hunting. They have increased from 100 but #PalmOil #deforestation in #PapuaNewGuinea is a threat #BoycottPalmOil #Boycott4Wildlife @palmoildetect #marsupial https://palmoildetectives.com/2021/01/26/tenkile-dendrolagus-scottae/

With their dense chocolate-brown fur, rounded face, and short, bear-like snout, Tenkile tree kangaroos are uniquely striking among their species. Their long, powerful tail helps them maintain balance while navigating the treetops, though unlike many tree kangaroos, they spend a significant amount of time on the ground. They move carefully and cautiously, using their strong forelimbs to grip branches and their hind legs for leaping between trees.

These tree kangaroos are highly elusive and difficult to spot in the wild. They are usually solitary, but historical accounts suggest they may have once lived in small groups. Due to intense hunting pressure, they have become particularly wary of human presence and avoid areas of disturbance.

Diet

Although no formal diet studies have been conducted, Tenkile tree kangaroos are known to feed on a variety of forest plants, vines, and epiphytes. They have been observed consuming Scaevola and Tetracera vines, as well as leaves from various rainforest species such as Podocarpus, Libocedrus, Auraucaria, Rapanea, and Syzygium. Their diet suggests they play a crucial role in their ecosystem by dispersing seeds and maintaining the health of montane rainforests.

Reproduction and Mating

Unlike some marsupials, Tenkile tree kangaroos do not have a fixed breeding season. Females typically give birth to one or possibly two joeys, which they carry in their pouch while they develop. Very little is known about their reproductive cycle, but as with other tree kangaroos, joeys likely spend months in the pouch before emerging and learning to navigate their treetop habitat. Given their slow reproductive rate, any decline in population is extremely difficult to reverse.

Threats

The Tenkile faces severe threats from hunting and habitat destruction for palm oil, gold mining and timber already present throughout their range.

This species is listed as Critically Endangered because of a rapid population decline suspected to be 90% or more over the last three generations, which in this species is a period of 30 years

IUCN Red List

Hunting and human encroachment

For generations, local communities hunted the Tenkile for food, leading to devastating population declines. Increased human population density has made this worse, as more people depend on hunting. However, conservation efforts have drastically reduced hunting, helping stabilise the species in the Torricelli Mountains.

Infrastructure and road construction

Around 75% of the Tenkile’s inferred range is now covered by timber and palm oil concessions, leading to widespread forest loss and fragmentation. Additionally, new roads built for petroleum and gas development have opened up previously inaccessible areas to hunters, worsening the threat.

Palm oil and industrial agriculture

Large-scale palm oil plantations are intruding into the Tenkile’s habitat. As corporate logging and agribusiness expands, the risk of palm oil and commercial plantations replacing their habitat has become a grave risk to their survival.

Climate change-induced extreme weather

As a forest-dwelling species, the Tenkile is highly sensitive to temperature changes. Climate change threatens to alter forest composition, food availability, and disease prevalence, putting additional stress on their already fragile population.

Take Action!

The Tenkile’s survival depends on protecting its rainforest home and ensuring local communities are supported in sustainable conservation efforts. You can help by using your wallet as a weapon—#BoycottPalmOil #Boycott4Wildlife every time you shop.

FAQs

What does the Tenkile eat?

The Tenkile’s diet consists mainly of forest vines, leaves, and epiphytic ferns, with a preference for plant species like Scaevola and Tetracera. These seed-dispersing tree kangaroos play a crucial ecological role in maintaining rainforest biodiversity.

How is the Tenkile different from other tree kangaroos?

Unlike most tree kangaroos, the Tenkile spends a high proportion of time on the ground rather than staying exclusively in the treetops. This makes them more vulnerable to hunting and habitat destruction.

Why are Tenkile tree kangaroos endangered?

The Tenkile has been severely impacted by hunting and habitat loss from logging, agriculture, and road construction. Despite successful conservation efforts, threats from industrial expansion and climate change continue to endanger its survival.

What is the Tenkile Conservation Alliance (TCA)?

The Tenkile Conservation Alliance is a community-driven conservation group that has helped protect the Tenkile by working with local villages to ban hunting and establish conservation of tree kangaroos and other small marsupials in Papua. Their work has stabilised the Tenkile’s population, proving that local-led conservation efforts can be effective.

How can I help protect the Tenkile?

One of the biggest threats to Tenkile habitat is deforestation, particularly for logging, agriculture, and palm oil expansion. Always choose products that are 100% palm oil-free to avoid contributing to deforestation and biodiversity loss. Support organisations like the Tenkile Conservation Alliance, and spread awareness about this critically endangered species.

Black Dorcopsis Dorcopsis atrata

Black Dorcopsis Dorcopsis atrata

IUCN Red List Status: Critically Endangered

Location: The Black Dorcopsis, also known as the Black Forest Wallaby, is found only on Goodenough Island in the D’Entrecasteaux Archipelago, Papua New Guinea. They inhabit lowland and montane forests, preferring dense vegetation at elevations between 300 and 1,500 metres.

The Black Dorcopsis is a rare and elusive wallaby, crucial to the health of Goodenough Island’s forest ecosystem in Papua New Guinea. However, their survival is under severe threat due to hunting and the relentless destruction of their habitat by logging, palm oil plantations, and subsistence agriculture. Without urgent conservation action, this unique species could vanish forever. Protecting them requires halting deforestation, boycotting palm oil, and supporting indigenous-led conservation initiatives. #BoycottPalmOil #Boycott4Wildlife

• Their dark grey to black fur, with subtle grey accents, helps them blend seamlessly into the shadows of the forest, making them almost invisible to predators and humans.
• Despite their nocturnal and elusive nature, they are a keystone species, playing a critical role in maintaining the health of Goodenough Island’s forests.

The Black Dorcopsis is a medium-sized macropod with a dense coat of fur ranging in colour from dark grey to black. Subtle grey highlights appear on their face, chest, and undersides, softening the otherwise dark hues. This unique colouring offers effective camouflage in the dimly lit forest undergrowth.

Adults weigh up to 8 kilograms and measure around 50 centimetres in body length, with an additional 30–40 centimetres for their long, tapering tail. Their strong hind legs and short, muscular forelimbs allow them to move swiftly and silently through rugged terrain. Black Dorcopsis like many other macropods and tree kangaroos are shy and nocturnal, emerging under the cover of darkness to forage. Their secretive nature makes them a challenge to study in the wild.

Diet

Black Dorcopsis are herbivores, feeding on a diet of fruits, leaves, roots, and other vegetation found on the forest floor. Their role as seed dispersers makes them crucial to the health and regeneration of Goodenough Island’s forests. By consuming and spreading seeds, they contribute to maintaining the biodiversity of their ecosystem.

Reproduction and Mating

Like other macropods, the Black Dorcopsis gives birth to a single joey after a short gestation period. The joey remains in the mother’s pouch for several months, continuing to develop until it is ready to emerge. Although specific details of their reproductive habits are unknown, their life cycle likely mirrors other forest wallabies, involving strong maternal care and seasonal breeding.

Geographic Range

This critically endangered wallaby is endemic to Goodenough Island, a small volcanic island with rugged terrain and limited forest cover. Their range is confined to approximately 687 square kilometres of lowland and montane forests. Habitat fragmentation and human encroachment have reduced their available range, isolating populations into smaller patches and threatening their long-term survival.

Threats

The forest habitat of this species is being cleared by slash-and-burn agriculture and is rapidly being converted to grassland.

IUCN Red List

Palm Oil and Timber Deforestation:

Logging for timber plantations and the expansion of out-of-control palm oil plantations are the most significant threats to the Black Dorcopsis. These activities destroy vital forests, leaving the wallabies with fewer safe areas to live and forage. Habitat loss and fragmentation reduce their chances of survival and force them into contact with humans, increasing hunting pressures.

Illegal Hunting:

The Black Dorcopsis is heavily hunted for subsistence by local communities. Despite their small population size and critically endangered status, hunting remains a significant threat, exacerbated by their restricted range.

Slash-and-Burn Agriculture:

The practice of clearing forests for subsistence farming depletes the habitat of Black Dorcopsis, further isolating their populations and limiting the resources available for foraging and reproduction.

Climate Change:

Rising temperatures and shifting rainfall patterns threaten the montane forests that the Black Dorcopsis depends on. As a high-altitude specialist, this species is particularly vulnerable to these changes, which degrade their already limited habitat.

Ecological Role

As herbivores, Black Dorcopsis are vital to the ecosystem of Goodenough Island. By consuming forest fruits and dispersing seeds, they contribute to the regeneration of vegetation and maintain the biodiversity of their habitat. Their presence is essential to the balance and health of this unique forest ecosystem.

Take Action

The Black Dorcopsis is teetering on the edge of extinction, and their survival depends on immediate action. Boycott palm oil products, demand responsible forestry practices, and support indigenous-led conservation initiatives in Papua New Guinea. Raising awareness and advocating for stronger protections for their habitat are crucial to ensuring this unique species does not disappear. #BoycottPalmOil #Boycott4Wildlife
