Blue Ridge Ultramafic Barrens and Woodlands (often called Serpentine Woodlands) are very rare natural communities made up of a mosaic of barrens, glades, and woodlands with outcroppings of dark, heavy, ultramafic rock, such as dunite, soapstone and serpentine. These rocks are very high in iron and magnesium, which inhibit the growth of some plants, and may also contain levels of copper and nickle that are toxic to some plants. Soils are shallow, and very quick draining, leading to dry conditions.
What's special: The rare and difficult conditions created by the bedrock result in a unique assemblage of plants that can tolerate the habitat. Many rare species grow here that occur nowhere else, because they cannot compete with plants in more common conditions.
Related communities: Grades into Pine-Oak Woodlands or Oak forest and has many species in common with Mafic Domes and Acidic Cliffs.
