CEGL006000 Quercus rubra - Betula alleghaniensis / Osmunda cinnamomea Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Northern Red Oak - Yellow Birch / Cinnamon Fern Forest

Colloquial Name: Upland/Wetland Transitional Forest

Hierarchy Level:  Association

Type Concept: This lower slope, wetland transitional forest of southern New England to New Jersey generally occurs immediately upslope from seasonally flooded acidic swamps or small drainages. It occurs on somewhat poorly drained mineral soils, with a soil moisture regime of moist to somewhat wet. The tree canopy is nearly closed, with tree height reflecting moisture availability. Dominant species include Acer rubrum, Betula alleghaniensis, Quercus rubra, and Quercus velutina. Occasionally Quercus alba, Quercus palustris, Fagus grandifolia, and Tsuga canadensis may occur. The shrub layer includes Hamamelis virginiana, Vaccinium corymbosum, Clethra alnifolia, Kalmia latifolia, and Lindera benzoin. The herbaceous layer is nearly continuous and dominated by Osmunda cinnamomea, Thelypteris noveboracensis, Arisaema triphyllum, and Uvularia sessilifolia.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: The lack of surface water and drier soil conditions during the growing season (relative to adjacent, seasonally flooded wetlands) make this forest suitable for species found more frequently in uplands.

Floristics: The tree canopy is nearly closed, with tree height reflecting moisture availability. Dominant species include Acer rubrum, Betula alleghaniensis, Quercus rubra, and Quercus velutina. Occasionally Quercus alba, Quercus palustris, Fagus grandifolia, and Tsuga canadensis may occur. Liriodendron tulipifera is a common associate in the southern portion of the range. The shrub layer includes Hamamelis virginiana, Vaccinium corymbosum, Clethra alnifolia, Kalmia latifolia, and Lindera benzoin. The herbaceous layer is nearly continuous and dominated by Osmunda cinnamomea, Thelypteris noveboracensis, Arisaema triphyllum, and Uvularia sessilifolia. Impatiens capensis, Veratrum viride, and Symplocarpus foetidus may also occur where this vegetation grades into a wetland forest.

Dynamics:  No Data Available

Environmental Description:  This vegetation occurs on lower slopes, generally adjacent to wetlands. Mineral soils are somewhat poorly drained and moist to somewhat wet sandy loams. The substrate is often rocky.
