Description:
This association is a dry, rich oak-hickory forest of the northeastern United States, occurring from Maine and Vermont to Pennsylvania and northern New Jersey. It is dominated by a mixture of hickories and oaks over a hop-hornbeam subcanopy with or without a parklike sedge lawn. The vegetation occurs on low-elevation ridgetops, upper slopes, south- or west-facing sideslopes, and is supported by well-drained loams or sandy loams, often derived from alkaline bedrock. The tree canopy, which ranges from nearly closed forest to partially open woodland, is dominated by a mixture of <i>Carya glabra, Carya ovata, Carya ovalis, Quercus rubra, Quercus alba, Quercus velutina</i>, with occasional <i>Ostrya virginiana</i> and <i>Acer rubrum</i>. Minor associates include <i>Acer saccharum, Pinus strobus</i>, and <i>Fraxinus americana</i>. A subcanopy of <i>Ostrya virginiana</i> is conspicuous in most areas. Additional species in the subcanopy or tall-shrub layer that occur in lower abundance can include <i>Hamamelis virginiana, Cornus florida, Amelanchier arborea, Acer pensylvanicum</i>, and <i>Viburnum acerifolium</i>. Low shrubs can include <i>Vaccinium angustifolium, Vaccinium pallidum, Rubus idaeus</i>, or <i>Viburnum rafinesquianum</i>. The herb layer can range from a sedge lawn of <i>Carex lucorum</i>, with some <i>Carex pensylvanica, Carex woodii, Carex appalachica</i>, or <i>Carex rosea</i>, to a more patchy herbaceous layer with sedges in addition to scattered <i>Elymus hystrix, Bromus pubescens, Ageratina altissima, Festuca subverticillata, Uvularia perfoliata, Aralia nudicaulis, Maianthemum racemosum (= Smilacina racemosa), Desmodium glutinosum, Desmodium paniculatum, Prenanthes alba, Solidago bicolor, Hepatica nobilis var. obtusa (= Hepatica americana), Carex</i> (Laxiflorae group), <i>Deschampsia flexuosa, Packera paupercula (= Senecio pauperculus), Packera obovata (= Senecio obovatus), Symphyotrichum undulatum (= Aster undulatus), Symphyotrichum patens (= Aster patens), Polystichum acrostichoides</i>, and <i>Dichanthelium</i> spp. Spring ephemerals such as <i>Erythronium americanum</i> and <i>Claytonia virginica</i> also occur in some portions of the range.
