Aesculus flava - Acer saccharum - (Tilia americana var. heterophylla) / Hydrophyllum canadense - Solidago flexicaulis Forest

Description:
This association includes forests of protected coves in the southern Appalachian Mountains of eastern Tennessee, western North Carolina, and southwest Virginia. This type extends peripherally into the Cumberland Mountains and Ridge and Valley of southwestern Virginia. These forests are associated with nutrient-rich soils and, often, mafic geologies, and occur on steep, middle to low protected slopes and coves at 610-1400 m (2000-4600 feet) elevation. Examples of this association have deciduous forest canopies dominated by either <i>Acer saccharum, Aesculus flava, Fraxinus americana, Halesia tetraptera var. monticola</i>, or <i>Tilia americana var. heterophylla</i>, or by various combinations of these species. Other common canopy species can include <i>Carya cordiformis</i> and <i>Quercus rubra</i>. A shrub stratum is very sparse or absent, and the herbaceous stratum is dense and luxurious, with high species richness. The defining feature of this association is the lush herbaceous flora with many calciphilic species indicative of high pH or circumneutral soils. Characteristic species include <i>Asarum canadense, Carex plantaginea, Cymophyllus fraserianus, Cystopteris protrusa, Deparia acrostichoides, Diplazium pycnocarpon, Dryopteris goldieana, Hepatica nobilis var. acuta, Hydrophyllum canadense, Osmorhiza claytonii, Prosartes lanuginosa, Solidago flexicaulis</i>, and <i>Viola canadensis</i>. The herbaceous stratum can have local dominance by <i>Laportea canadensis, Viola canadensis, Dryopteris intermedia, Actaea podocarpa, Actaea racemosa</i>, and <i>Caulophyllum thalictroides</i>. This forest lacks dominance by <i>Betula alleghaniensis</i> and <i>Fagus grandifolia</i>, and has an herbaceous flora indicative of high-base status soils. This association typically has a much more diverse herbaceous stratum than other deciduous cove forests of the Southern Blue Ridge.
