Name: Picea rubens - (Tsuga canadensis) / Rhododendron maximum Saturated Forest Reference: Eastern Ecology Working Group of... Description: This spruce-hemlock wetland forest of the central and southern Appalachian Mountains occurs on relatively flat terrain in poorly drained bottomlands of small streams at high elevations (above 3500 feet elevation in the Southern Blue Ridge to above 2000 feet in the central Appalachians). It historically occurred in Tennessee. Soils are seasonally to semipermanently saturated due to a high water table or seepage from adjacent slopes. The tree canopy is dominated by Picea rubens or mixtures of Picea rubens and Tsuga canadensis. Other tree species that may occur in the canopy or subcanopy include Tsuga canadensis, Betula alleghaniensis, Acer rubrum var. rubrum, Taxus canadensis, and Amelanchier arborea. This forest often has a dense shrub layer dominated by Rhododendron maximum with other associates often including Kalmia latifolia, Ilex verticillata, Ilex collina, Viburnum nudum var. cassinoides, Photinia melanocarpa (= Aronia melanocarpa), and Vaccinium spp. The herbaceous layer is sparse, with the majority of herbaceous species restricted to openings, and includes Carex trisperma, Carex folliculata, Glyceria melicaria, Osmunda cinnamomea, Osmunda regalis, and Maianthemum canadense. Listera smallii, Oclemena acuminata (= Aster acuminatus), Huperzia lucidula, and Dryopteris campyloptera are characteristic herbs. The bryophyte layer is of variable cover but is dominated by Sphagnum. The absence of Abies balsamea and the importance of Rhododendron maximum differentiate this forest from Picea rubens - Abies balsamea / Sphagnum magellanicum Forest (CEGL006311).  Accession Code: VB.CC.20906.PICEARUBENSTSUG Plot-observations of this Community Concept: 0
