The parma wallaby (Notamacropus parma) [2] is a small marsupial macropod mammal native to forests and densely-vegetated areas of northeastern New South Wales, Australia, close to the border with Queensland. There is also an introduced population found in and around Rodney District, just north of Auckland, New Zealand. About the size of a stout cat, it lives mainly under thick plant cover, and is only active at night when it emerges to feed on grasses and small plants. It is the smallest of the wallabies (short, kangaroo-like marsupial mammals of the genus Notamacropus ) and carries its young in a pouch, as with other marsupials. Shy and elusive, it was believed extinct until its rediscovery in the 1960s.
Parma wallabies are threatened by habitat loss, and, in addition to native predators (such as birds of prey, monitor lizards, and snakes), they are easily preyed upon by dingoes and non-native feral cats and red foxes. [1]
The parma wallaby was first described by British naturalist John Gould in about 1840. Its epithet parma (Waterhouse 1845) comes after a word from a New South Wales Aboriginal language, but the exact source word and language have not been identified. [3]
In 2019, a reassessment of macropod taxonomy determined that Osphranter and Notamacropus , formerly considered subgenera of Macropus , should be moved to the genus level. [4] This change was accepted by the Australian Faunal Directory in 2020. [5]
A shy cryptic creature of the wet sclerophyll forests of northern New South Wales (Australia), it was never commonly-encountered and, even before the end of the 19th century, it was believed to be extinct.
In 1965, workers on Kawau Island, New Zealand (near Auckland), trying to control a plague of introduced tammar wallabies (a widespread and fairly common species in Australia), were astonished to discover that some of the animals were not truly tammar wallabies, but a miraculously surviving population of parma wallabies - a species long-thought extinct. The extermination effort was put on-hold while individuals were captured and sent to institutions in Australia and around the world in the hope that they would breed in captivity and could eventually be reintroduced to their native habitat.
The renewed interest in the parma wallaby soon led to another milestone: in 1967 it was found that they still existed in the forests near Gosford, New South Wales. Further investigation showed that the parma wallaby was alive and well, and although not common, was to be found in forests along the Great Dividing Range from near Gosford almost as far north as the Queensland border.
The offspring of the Kawau Island population are smaller than their fully-wild, Australian relatives, even when provided with ample food; it appears that competition, for limited food resources on the island, selects for smaller individuals, an incipient example of the evolutionary phenomenon of insular dwarfism.
The parma wallaby is the smallest member of the genus Notamacropus, at between 3.2 and 5.8 kg (7.1 and 12.8 lb), less than one-tenth the size of the red kangaroo. It is about 0.5 m (1.6 ft) in length, with a sparsely furred, blackish tail about the same length again. The fur is a reddish or greyish brown above, greyer about the head, and fading to pale grey underneath. Presumably, individuals had been sighted many times during the years when it was "extinct", but mistaken for an especially slender and long-tailed example of the otherwise similar red-legged and red-necked pademelons.
The Parma wallaby inhabits wet sclerophyll (hard-leaved) forests of northern New South Wales, Australia. Like the pademelon, it prefers forest with thick undergrowth, and grassy patches, although parma wallabies are also found occasionally in dry eucalypt forest and even rainforest. It is mainly nocturnal and usually shelters in thick scrub during the day, through which it can travel at speed along the runways it makes. It emerges from cover shortly before dusk to feed on grasses and herbs in forest clearings. The parma wallaby is largely solitary, with two or at most three animals sometimes coming together to feed in favourable circumstances.
The species remains rarely seen, with some evidence for a recent population decline. It is classified as Near Threatened according to the 2015 IUCN assessment. [1]
A wallaby is a small or middle-sized macropod native to Australia and New Guinea, with introduced populations in New Zealand, Hawaii, the United Kingdom and other countries. They belong to the same taxonomic family as kangaroos and sometimes the same genus, but kangaroos are specifically categorised into the four largest species of the family. The term "wallaby" is an informal designation generally used for any macropod that is smaller than a kangaroo or a wallaroo that has not been designated otherwise.
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 red-necked wallaby or Bennett's wallaby is a medium-sized macropod marsupial (wallaby), common in the more temperate and fertile parts of eastern Australia, including Tasmania. Red-necked wallabies have been introduced to several other countries, including New Zealand, the United Kingdom, Ireland, the Isle of Man, France and Germany.
The tammar wallaby, also known as the dama wallaby or darma wallaby, is a small macropod native to South and Western Australia. Though its geographical range has been severely reduced since European colonisation, the tammar wallaby remains common within its reduced range and is listed as "Least Concern" by the International Union for Conservation of Nature (IUCN). It has been introduced to New Zealand and reintroduced to some areas of Australia where it had been previously extirpated. Skull variations differentiate between tammar wallabies from Western Australia, Kangaroo Island, and mainland South Australia, making them distinct population groups.
Pademelons are small marsupials in the genus Thylogale, found in Australia and Aru, Kai plus New Guinea islands. They are some of the smallest members of the macropod family, which includes the similar-looking but larger kangaroos and wallabies. Pademelons are distinguished by their small size and their short, thick, and sparsely-haired tails. Like most other marsupials, they carry their young in a pouch.
The crescent nail-tail wallaby, also known as the worong, was a small species of marsupial that grazed on grasses in the scrub and woodlands of southwestern and central Australia. They were common in Western Australia before they disappeared in the early 20th century and persisted in the central deserts until at least the 1950s. The pelage was soft and silky and an ashen grey colouring overall, highlighted in part with rufous tones. There were light and dark patches of fur across the body, the moon-like crescents inspiring their names, and had attractive stripes on the face. Like the two remaining species of the genus, the northern Onychogalea unguifera and rare O. fraenata, it had a horny spur at the tip of its tail. The species was compared to a hare or rabbit, in its habits, appearance and taste, and weighed around 3.5 kilograms.
The toolache wallaby or Grey's wallaby is an extinct species of wallaby from southeastern South Australia and southwestern Victoria.
The swamp wallaby is a small macropod marsupial of eastern Australia. This wallaby is also commonly known as the black wallaby, with other names including black-tailed wallaby, fern wallaby, black pademelon, stinker, and black stinker on account of its characteristic swampy odour.
Macropus is a marsupial genus in the family Macropodidae. It has two extant species of large terrestrial kangaroos. The term is derived from the Ancient Greek μάκρος, makros "long" and πους, pous "foot". Thirteen known extinct species are recognised. The type species is the eastern grey kangaroo.
The whiptail wallaby, also known as the pretty-faced wallaby, is a species of wallaby found in eastern Australia. It is locally common from Cooktown in Queensland to near Grafton in New South Wales.
The western brush wallaby, also known as the black-gloved wallaby, is a species of wallaby found in the southwestern coastal region of Western Australia. The wallaby's main threat is predation by the introduced red fox. The IUCN lists the western brush wallaby as Least Concern, as it remains fairly widespread and the population is believed to be stable or increasing, as a result of red fox control programs.
The northern or sandy nail-tail wallaby is a species of macropod found across northern Australia on arid and sparsely wooded plains. The largest species of the genus Onychogalea, it is a solitary and nocturnal herbivorous browser that selects its food from a wide variety of grasses and succulent plant material. Distinguished by a slender and long-limbed form that resembles the typical and well known kangaroos, although their standing height is shorter, around half of one metre, and their weight is less than nine kilograms. As with some medium to large kangaroo species, such as Osphranter rufus, they have an unusual pentapedal motion at slow speeds by stiffening the tail for a fifth limb. When fleeing a disturbance, they hop rapidly with the tail curled back and repeatedly utter the sound "wuluhwuluh". Their exceptionally long tail has a broad fingernail-like protuberance beneath a dark crest of hair at its end, a peculiarity of the genus that is much broader than the other species. The name unguifera, meaning claw, is a reference to this extraordinary attribute, the purpose of which is unknown.
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.
Calaby's pademelon, also known as the alpine wallaby, is a species of marsupial in the family Macropodidae. It is endemic to Papua New Guinea. It is threatened by habitat loss and hunting.
Osphranter is a genus of large marsupials in the family Macropodidae, commonly known as kangaroos and wallaroos. It contains the largest extant marsupial, the red kangaroo.
Notamacropus is a genus of small marsupials in the family Macropodidae, commonly known as wallabies. The term is derived from the Latin nota "stripe" and macropus "kangaroo", referencing the distinct facial stripe of many extant genus members and their phylogenetic relationship to other kangaroos.
