South-Central Interior Mesophytic Forest Macrogroup: Northern Hardwood & Conifer yourStateNatural Heritage Ecologist for more information about this habitat. This is modeledmap a distributiononbased current and is data nota substitute for field inventory. based Contact © Brian Streets (West Virginia Division of Natural Resources) Description: A high-diversity, predominately hardwood forests that occurs on deep and enriched lowland soils or in somewhat protected landscape positions such as coves or lower slopes. Dominant species include sugar maple, beech, tuliptree, basswood, red oak, cucumber tree, and black walnut. Hemlock may be a component of some stands. Trees may grow very large in undisturbed areas. The herb layer is rich, often with abundant spring ephemerals. The core distribution of this system lies in the unglaciated Cumberland and Allegheny plateaus-- it occurs in our region only in the western and southern part.

Two similar systems are Southern and Central Appalachian Cove Forests and North-Central Interior Beech- Maple Forests; the first occurs from the Allegheny Mountains eastward, and the second is found to the north.
