Habitat
Although fishers are competent tree climbers, they spend most of their time on the forest floor. They prefer continuous forest to other habitats. Fishers have been found in extensive conifer forests typical of the boreal forest but are also common in mixed hardwood and conifer forests. Fishers prefer areas with continuous overhead cover with greater than 80% coverage and will avoid areas with less than 50% coverage. Fishers are more likely to be found in old-growth forests. Forests that have been heavily logged and have extensive second growth appears to be unsuitable for fisher habitat.
Another factor that fishers select for are forest floors that have large amounts of coarse woody debris. In western forests where fire regularly removes understorey debris, fishers show a preference for riparian woodland habitat. Fishers tend to avoid areas with deep snow. Habitat is also affected by snow compaction and moisture content.
