Description

The tree rat has a greyish-brown coat that is shaggy and coarse and has a creamy white underbelly. The hind feet are black with well developed pads and strong sharp claws. They have large ears and a long tail with a brush of white hair at the tip.[3] They grow to a mass of 830 grams (29 oz).[4] The height of the rat is typically 250 to 310 millimetres (9.8 to 12.2 in) with a length of 320 to 420 millimetres (13 to 17 in).[5]

Behaviour

The tree rat is solitary and nocturnal, it is arboreal sheltering in tree hollows and pandanus stands during the day.[4][5]

Feeding

It is a folivore and frugivore and its diet may be supplemented by invertebrates such as termites and molluscs.

Distribution

Mesembriomys gouldii has a range extending from the savannahs of Cape York Peninsula in Queensland westward to the Kimberley region of Western Australia.[5] Habitats such as tropical woodlands or open forest are suitable for the tree rat.[4] It is not commonly found across the area and the population has been reduced between 30 and 50% in the last decade.[5] The estimated population is 30,000.[5]
