Acer saccharum - Quercus muehlenbergii / Carex platyphylla Forest
Translated Name: Sugar Maple - Chinquapin Oak / Broadleaf Sedge Forest
Common Name: Sugar Maple - Chinquapin Oak / Sedge Forest
Unique Identifier: CEGL006162
Classification Approach: International Vegetation Classification (IVC)
Summary: This dry calcareous forest occurs on upper slopes and wooded summits on limestone, dolomite or marble bedrock in the northeastern United States. The somewhat open canopy is characterized by a diversity of tree species, including Acer saccharum, Quercus muehlenbergii, Tilia americana, Fraxinus americana, and occasionally Liriodendron tulipifera, Quercus alba, Quercus prinus, Juglans cinerea, Juglans nigra, Carya cordiformis, Ulmus rubra, Carya ovata, or Carya ovalis. Ostrya virginiana, Betula lenta, Carya tomentosa, Celtis occidentalis, and/or Cornus florida often form a subcanopy. Shrubs can include Hamamelis virginiana, Carpinus caroliniana, Staphylea trifolia, Cornus alternifolia, Viburnum acerifolium, Ribes americanum, and occasionally Zanthoxylum americanum or Viburnum rafinesquianum. Vines may include Dioscorea villosa, Menispermum canadense, Parthenocissus quinquefolia, and Toxicodendron radicans. The herb layer is extraordinarily diverse with Packera obovata, Carex eburnea, Carex platyphylla, Polygala senega, Aquilegia canadensis, Aureolaria flava, Patis racemosa, Anemone virginiana, Hepatica nobilis var. obtusa, Symphyotrichum patens, Symphyotrichum undulatum, Triosteum aurantiacum, Thalictrum dioicum, Clematis occidentalis, Asclepias quadrifolia, Arabis canadensis, Geranium maculatum, Penstemon hirsutus, Trillium grandiflorum, Osmorhiza claytonii, Actaea pachypoda, Agastache nepetoides, Allium tricoccum, Arabis lyrata, Arisaema triphyllum, Asclepias exaltata, Collinsonia canadensis, Dichanthelium boscii, Carex laxiflora, Trichophorum planifolium, and many others. Bedrock outcrops and boulders are common. Southern species tend to drop out at the northern extent of this type.
