Taiga is the Russian word for big areas of forest wilderness in high latitude regions. What about forests in the mountains? What is the name for the forested areas in mountains which are below the treeline?
Between timberline and treeline lies "krumholtz", a German word meaning broken or bent wood".
Great place to hike.
The US National Park Service refers to a forested area directly below tree line as "subalpine forest." (NPS - Subalpine Forest).
