Mountain Brush-tailed Possum (Trichosurus cunninghami) lives in eastern Australian forests across Southeastern Australia. Its conservation status is Least Concern.
Fascinating facts about the Mountain Brush-tailed Possum
- Only in 2002 did scientists finally split the mountain brushtail possum from its northern cousin, proposing two species based on morphometric differences. A few years later, in 2005, researchers uncovered a hidden colony in swampy coastal habitat of south-west Gippsland, showing the species occupies more than just alpine forest. This recent discovery forces a rethink of its common name, the "mountain" label no longer fits a marsupial that also thrives in low-lying wetlands, highlighting how much we still miss about its true distribution.
- Bobucks weigh between 2.5 and 4.5 kg (5.5-9.9 lb), making them medium-sized marsupials, and they normally live above 300 metres (980 ft) altitude. Their body length ranges from 81 to 93 cm, and they sport a thick, light gray-brown coat with a long, bushy tail. These concrete dimensions mean the animal can easily slip into tree hollows or dense ground cover.
- In the high country, mountain brushtail possums rely heavily on Acacia species, especially the silver wattle (Acacia dealbata), for most of their diet, while lowland Gippsland individuals are found in a variety of Eucalypt species stands or Tea Tree. Bobucks also forage on the ground, eating fungi that grow below (hypogeal) and above (epigeal) the soil.
- Mating happens over a tight 2-3 week window each autumn (March, June), and females give birth to a single joey each year. Young males may travel up to 8 km (5 mi) away from their birth site, while females tend to stay close to home, often remaining in the same den for life.
- Both male and female mountain brushtail possums can live to at least 12 years, making them perhaps the longest-lived marsupial species. Adults guard a mean home-range of about 6.0 hectares (±0.4 ha) and stay sedentary, often occupying the same small area for life. Such longevity combined with tiny territories means each individual can have a lasting impact on local vegetation through repeated herbivory, while also highlighting how habitat loss can threaten these long-lived residents.

About the Mountain Brush-tailed Possum
In the misty, moonlit forests of the Australian mountains, the Mountain Brush-tailed Possum weaves a silent, arboreal path, its dense fur fluffed against the chill as it navigates the labyrinthine canopy with effortless ease. With eyes aglow like lanterns in the dark, this nocturnal phantom pads across branches, its prehensile tail a counterbalance to its every move, a remarkable adaptation that allows it to traverse the vertical world with the agility of a ghost. As it forages for leaves and fruits, its gentle, whispery movements belie a resilience that has earned it a place among the most thriving of Australia's native creatures.
