The forest consists of mainly mixed woodland including Norway and Sitka spruce, Ash, Oak and Beech.
Along with the the Central and North Coast regions of British Columbia designated by environmental groups as the Great Bear Rainforest, the Tongass is part of the "perhumid rainforest zone", and the forest is primarily made up of western red cedar, sitka spruce, and western hemlock.
