Piedmont Oak-Pine Woodlands
Woodlands are different than forests in that there are gaps in the canopy that let roughly 20- 80% of all sunlight in to the forest floor. Pines and dry-site oaks dominate. Usually the shrub layer is sparse, allowing a lush ground cover to develop. Woodlands grow on sites that are too dry to support a closed canopy, such as on sharp ridges or slopes with stony, thin soils. Very often, also grow on moister sites where fire keeps the site open (look for fire scars on tree trunks), and as a mid successional phase as vegetation begins growing back after a site was cleared.
What's special: The combination of trees and, often, the lush ground cover allowed by the sunlight reaching the forest floor creates many different habitats and niches for wildlife, adding a lot of plant and animal diversity to the landscape.
Common Trees: Loblolly pine, shortleaf pine, blackjack oak, post oak, rock chestnut oak and scarlet oak.
Related Communities: As the tree cover gets more dense, this community grades into Piedmont Oak-Pine Forest. The presence of rock outcrops along with an abundance of white ash, eastern red cedar, and hickories would indicate that there is mafic rock present, and the community is most likely the "Glades, Barrens & Woodlands" community.
