TNC Alliance Description:  The canopy of this vegetation is dominated by Quercus velutina and Q. albaCarya tomentosa and Quercus coccinea are common canopy or subcanopy associates. Other canopy associates may include Robinia pseudoacacia, Nyssa sylvatica, Prunus serotina or Pinus rigida. The shrub layer contains Quercus species present in the canopy, especially Q. alba, with Sassafras albidum, Vaccinium corymbosum, and/or Viburnum dentatum occurring locally. Gaylussaccia baccata is often present in the short shrub layer with considerable cover.  Vines, where present, tend to be abundant, especially Smilax rotundifolia.  The herbaceous layer is generally sparse to absent.
 

Photo Interpretation: This type covers a large portion of the William Floyd Estate. It appears on the photography as a tall, forested area with a tan or brown color stippled with shadows from tree trunks oriented all in the same direction. Individual green Pinus rigida is often present but not in high enough proportion to classify as coniferous forest.
