long-footed potoroo

By Mark Irwin

Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Mammalia
Order: Diprotodontia
Suborder: Macropodiformes
Family: Potoroidae
Genus: Potorous
Species: Potorous longipes

Geographic Range

Only found in the forests of south-eastern Australia. Specifically, forests of East Gippsland, north-eastern Victoria south of Mount Buffalo, and south-eastern New South Wales.

Biogeographic Regions:
australian (native ).

Habitat

Mostly found in a range of predominantly "wetter" forest types, from wet sclerophyll forests at an altitude of 800m to lowland sclerophyll forests and warm temperate rainforest at 150m. Limited to areas with high soil moisture content throughout the year (because of ecology of food items) and areas with densely vegetated locations for shelter. Most Long-footed Potoroos are found in sites with an average annual rainfall of 1100 to 1200mm (43 to 47in).

Terrestrial Biomes:
forest .

Physical Description

Mass
1 to 2 kg; avg. 2000 kg
(2.2 to 4.4 lbs; avg. 4400 lbs)


Potoroos are small kangaroos also called "rat-kangaroos." Males are most often heavier than females. About the size of a rabbit (700mm of which 300mm is the tail), Potorous longipes can be distinguished from other potoroos by its long back feet and toes. Members of the species also have strong front feet and claws. The fur of the mammal is dense, with a soft grey-brown color that is paler on the stomach and feet.

Some key physical features:
endothermic ; bilateral symmetry .

Reproduction

Gestation period
38 days (average)

Age at sexual or reproductive maturity (female)
755 days (average)
[External Source: AnAge]


Most young are born in the winter, spring, and early summer, but the Long-footed Potoroo likely breeds throughout the year. There can be several litters per year (1 young per litter), with the average being 2.5 to 3 young per year. Young remain in the pouch for 140 to 150 days.

Key reproductive features:
gonochoric/gonochoristic/dioecious (sexes separate); sexual .

Behavior

Terrestrial animal that obtains its food by digging conical pits with its forefeet. It is nocturnal and shelters in dense vegetation (ferns or thickets of wire grass) during the day to avoid predators.

Key behaviors:
motile .

Food Habits

Obligate fungivore, feeding on the fruiting bodies of more than 30 species of underground fungi, which grow in association with tree roots. Occasionally insects, seeds, and other plant materials become a part of the diet, which is 80% fungi. Feeding locations are easily identified by small, cone-shaped holes, dug in search of fungi.

Conservation Status

IUCN Red List: [link]:
Endangered.

Populations are threatened by habitat loss or fragmentation caused by logging and road construction associated with logging. Wildfire and fuel-reduction burning practices also threaten populations. Introduced predators, including the Red Fox, Dingo, and feral Dog, are important causes of mortality of the Long-footed Potoroo. Conservation efforts are being made by the Department of Natural Resources and Environment in Australia. These efforts include careful management in National Parks (2 known populations in Snowy River National Park), establishment of special management areas, predator control in management areas, long-term monitoring of populations, and public education about the Long-footed Potoroo.
