Ecological community groups with distributions centered below 1,070 m (3,500 ft) elevation and representing xerophytic to submesophytic forest vegetation. A few community types of the Montane Mixed Oak and Oak-Hickory Forests and Oak / Heath Forests extend significantly into the high-elevation zone (> 1,070 m, 3,500 ft), but are retained in this Class because of their compositional similarity to other members of these groups.
Montane Dry and Dry-Mesic Calcareous Forests
Coastal Plain Dry Calcareous Forests
