Historic reports indicate a broad range of reasonably open habitats: grassy woodlands, coastal and alpine scrub, and open forests. Thylacines seem to have avoided the dense, wet rainforest of western and southwestern Tasmania. Their habitat preferences completely overlap with those of the devil and are consistent with the distribution of dense populations of prey. Tasmanian wolves are reported to have used dense vegetation and rocky outcrops during the day (probably for dens), hunt ing in adjacent open grassy woodlands and forests at night. The number of subfossil remains found in caves in Tasmania attest to the use of larger caves as lairs.
