The parma wallaby (''Notamacropus parma'') is a small, hopping, kangaroo-like mammal native to forests of southeastern Australia. About the size of a stout cat, it lives in dense shrub and is only active at night to feed on grasses and small plants. It is the smallest of the wallabies (short, kangaroo-like animals of the genus ''
Notamacropus'') and carries its young in a pouch like other
marsupials
Marsupials are any members of the mammalian infraclass Marsupialia. All extant marsupials are endemic to Australasia, Wallacea and the Americas. A distinctive characteristic common to most of these species is that the young are carried in a po ...
. Shy and elusive, it was believed extinct until rediscovery in the 1960s. It is threatened by habitat loss and is easily killed by non-native foxes.

Rediscovery and sightings
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.

(a widespread and fairly common species in Australia), were astonished to discover that some of the pests were not 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 relatives, even when provided with ample food: it appears that competition for limited food resources on the island selected for smaller individuals, an incipient example of the phenomenon of insular dwarfism.
Description
The parma wallaby is the smallest member of the genus ''Notamacropus'', at between , less than one-tenth the size of the red kangaroo. It is about 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.
Habitat and behavior
left
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.
Status
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.[
