Summary  Revegetation within cleared farming landscapes offers the potential to restore habitat for many woodland-dependent species that have declined since European settlement. Most species of arboreal marsupials require hollows for breeding and diurnal shelter, a resource that is usually available only in old trees; however, this constraint does not apply to the Koala. In this study, we describe the occupancy and use of young (4- to 7-year old) eucalypt plantations by Koalas in a predominantly cleared landscape used for intensive cropping and grazing. We compare Koala occupancy in 27 eucalypt plantations, 5 paddocks and 11 remnant forest and woodland sites, and we report the relative usage of these three land cover types by two adult male Koalas that were radio-tracked for 5 and 7 months using GPS transmitters. Koalas were recorded using young eucalypt plantations at 7 sites and remnant forest and woodland at 7 sites. Both radio-collared Koalas used eucalypt plantations more than expected based on the availability of this land cover type in their home-ranges. Occupancy of young eucalypt plantations and remnant patches by Koalas was strongly influenced by the proximity of these sites to remnant vegetation.
