Description:
This mixed hardwood - white pine - hemlock cove forest is widely but locally distributed in the southern part of the Central Appalachians in Virginia, West Virginia, and Maryland. It occurs on the lower slopes and bottoms of ravines and coves at lower elevations, generally below 915 m (3000 feet). Sites may be underlain by bedrock or colluvial and alluvial deposits of various sedimentary and metasedimentary rocks, granitic rocks, or metabasalt. Habitats are generally mesic with acidic soils of moderate or intermediate fertility. The overstory is codominated by variable mixtures of <i>Liriodendron tulipifera, Pinus strobus, Tsuga canadensis, Quercus rubra</i>, and <i>Quercus alba</i>. This forest generally has a moderate to strong evergreen component, but <i>Pinus strobus</i> varies from widely scattered to codominant, and <i>Tsuga canadensis</i> has been greatly reduced by recent outbreaks of the hemlock woolly adelgid and may be restricted to the understory. Less frequent overstory associates include <i>Acer rubrum, Betula lenta, Carya</i> spp., <i>Fagus grandifolia, Fraxinus americana, Nyssa sylvatica</i>, and <i>Quercus montana</i>. Characteristic understory species include <i>Acer pensylvanicum, Amelanchier arborea, Cercis canadensis, Cornus florida, Ostrya virginiana, Oxydendrum arboreum, Viburnum acerifolium, Rubus</i> spp., <i>Corylus americana, Hamamelis virginiana, Hydrangea arborescens</i>, and <i>Lindera benzoin</i>. The herb layer is usually patchy to moderately dense. Frequent patch-dominants include <i>Amphicarpaea bracteata, Dennstaedtia punctilobula, Eurybia divaricata</i>, and <i>Polystichum acrostichoides</i>. Other constant but low-cover herbs include <i>Botrychium virginianum, Desmodium nudiflorum, Dioscorea quaternata, Galium triflorum, Maianthemum racemosum ssp. racemosum, Mitchella repens</i>, and <i>Stellaria pubera</i>. Many additional herbs occur at low constancy.
