Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	Tolerates a wide variety of habitats, including cloud forests, brushlands, and riverbank chaparral. lt is typical of chaparral brusblands of Chile. This species presents an ample altitudinal range, from sea level to elevations of 2,500 m asl. Can be arboreal or terrestrial. Unlike other mouse opossums, Thylamys are found in the central and southern part of South America in dry habitats, as opposed to the more mesic environments of other genera (Palma et al. 2002). The species of this genus are mainly arobreal and crepuscular, with a diet that is mostly insects and small vertebrates (Palma et al. 2002).
