The term "piedmont" means foothills: the Piedmont ecoregion lies at the foot of the Appalachian Mountains, with a topography that ranges from rugged to gently rolling. It is made up of a mosaic of metamorphic rocks varying from mafic rocks that weather to high-nutrient soils to acidic rocks that weather to more sterile soils. (Learn more about the rock types and their influence on plants here.) The variation in topography and soils leads to a mix of natural communities: fire-influenced woodlands on acidic south-facing ridges, mesic forests on deep, fertile soils, and rock outcrops with panoramic views. |
