Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Sugar Maple - Northern Red Oak / Round-lobe Liverleaf Forest

Colloquial Name: Sugar Maple - Ash - Oak - Hickory Mesic Forest

Hierarchy Level:  Association

Type Concept: These are forests of well-drained to moist sites and often found on very rocky slopes. They are currently described from central and southern New England, extending to adjacent Canada and south to New Jersey. Fraxinus americana and Acer saccharum are common in the tree canopy, with Quercus rubra, Carya ovata, Carya glabra, Carya ovalis, Quercus velutina, Tilia americana, Betula lenta, and Quercus alba as associates. Tsuga canadensis can be occasional. Ostrya virginiana and Carpinus caroliniana can form a prominent subcanopy. The shrub layer includes Hamamelis virginiana, Viburnum acerifolium, Viburnum recognitum, Cornus florida, Corylus cornuta, and Lindera benzoin. The herb layer is often quite diverse with Carex platyphylla, Carex pedunculata, Carex blanda, Carex laxiflora, Actaea rubra, Polygonatum pubescens, Phegopteris hexagonoptera, Viola rotundifolia, Thalictrum dioicum, Hepatica nobilis var. obtusa, Thalictrum thalictroides, Festuca subverticillata, Actaea pachypoda, Viola sororia, Arabis spp., Packera obovata, and Arisaema triphyllum.
