II.
WOODLAND Concept: This alliance contains mixed woodlands of well-drained, nutrient-poor sandy soils, often closely associated with pine barrens communities. This alliance occurs less commonly on bedrock ledges. The canopy is usually dominated by Pinus rigida and Quercus coccinea, with Quercus velutina, Quercus alba, and Pinus strobus in association. Quercus ilicifolia, Quercus prinoides may form a subcanopy, and ericaceous shrubs such as Gaylussacia baccata, Vaccinium angustifolium, and Vaccinium pallidum are common. Light-demanding species are common in these communities: Schizachyrium scoparium, Arctostaphylos uva-ursi, Carex pensylvanica, Hudsonia tomentosa, Hudsonia ericoides, and Lechea mucronata (= Lechea villosa). Range: This alliance occurs in New York, southern New England, and likely occurs in New Jersey. Its occurrence outside the northeastern United States has not yet been evaluated. It does not occur in Maryland.

The open canopy is codominated by Pinus rigida and Quercus coccinea and/or Quercus velutina. Quercus alba and Pinus strobus may be present as well. The shrub layer may include Quercus ilicifolia, Quercus prinoides, and/or ericaceous shrubs such as Gaylussacia baccata, Vaccinium angustifolium, and Vaccinium pallidum. Light-demanding species such as Schizachyrium scoparium, Danthonia spicata, and Carex pensylvanica are common in this community. Other associates include Arctostaphylos uva-ursi, Hudsonia tomentosa, Hudsonia ericoides, and Lechea mucronata (= Lechea villosa). It occurs on well-drained, nutrient-poor sandy soils, often associated with pine barrens communities. It also occurs on bedrock ledges / ridges.
