%X Aspects of the ecology of Rattus lutreolus velutinus (Thomas) were studied in dry sclerophyll forest, buttongrass and heathland communities in north-eastern Tasmania. In each habitat environmental parameters which might influence the species' microhabitat selection (e.g, soil moisture, vegetation structure and floristics) and diet (e.g. monocotyledon food), were assessed. R. I, velutinus began to breed during late August. Sexually active males were captured between September and February, inclusive. Pregnant females were captured between September and November, and the number of lactating females peaked during November in all habitats. Juveniles were captured between December and February. R. I. velutinus was predominantly herbivorous, preferring stem and leaf tissue but also eating seeds, insects, roots and fungus. Captures of rats were positively correlated with vegetation cover less than 50 cm high and with a monocotyledonous food index. Population density was substantially higher in heathland than in buttongrass and dry sclerophyll forest. Animals had similar body condition in each habitat.
