Description: A hardwood forest of the coastal plain with a significant component of mesophytic (moist but non-wetland) species, such as American beech or southern sugar maple. Upland and bottomland oaks at the mid range of moisture tolerance are usually also present, particularly white oak, but sometimes also southern red oak, cherrybark oak, or Shumard oak. Loblolly pine is sometimes present, but it is unclear if it is a natural component or has entered only as a result of past cutting. Understories are usually well- developed. Shrub and herb layers may be sparse or moderately dense. Ranging south from to , these mostly large patch coastal plain forests State Distribution: DC, DE, MD, NJ, PA, VA occupy a variety of moist sites that are naturally sheltered from frequent fire.
