Description
The reference state supports three community phases, which are grouped by the structure and dominance of the vegetation (trees, shrubs, graminoids, and forbs) and by their ecological function and stability. The reference community phase is characterized by a birch forest and diverse understory that commonly consists of water-tolerant shrubs, graminoids, and forbs. The presence of the community phases is dictated temporally by erosion and the movement of surface or subsurface water. No alternate states have been observed.
