Papua grassland mosaic-tailed rat

The Papua grassland mosaic-tailed rat, Melomys lutillus, is a rodent in the family Muridae that is also called the grassland melomys. It is endemic to the island of New Guinea, where it is found from sea level up to altitudes of about 2,200 metres. As its name suggests it inhabits grassland, but it is also present in gardens and other disturbed areas, which shows that it tolerates a degree of human alteration of its surroundings. The International Union for Conservation of Nature has assessed its conservation status as least concern, on the grounds that it has a wide range, can tolerate disturbance to its habitat and faces no particular identified threats.
