    Description

    This guide presents the plant association classification for the western hemlock zone of the Gifford Pinchot National Forest. The bulk of the forest below about 3000 feet in elevation is included in this zone, comprising about one half of the entire landbase. Much of this area is blanketed with productive stands of Douglas-fir.
