Cumberland/Ridge & Valley Pine-Oak Woodlands
|
|
Woodlands let in roughly 20- 80% of all sunlight in to the forest floor. Pines and dry-site oaks dominate. Usually the shrub layer is sparse, sometimes allowing a lush ground cover to develop. Woodlands often grow on sites that are too dry to support a closed canopy, such as on sharp ridges or south-facing slopes with stony, thin soils. They are most common in this ecoregion on sandstone ridges with acidic soils. They also grow on moister sites with frequent fire and as a mid successional phase as vegetation returns after a site was cleared.
Indicator species: Virginia pine, shortleaf pine What's special: The combination of trees and when present, a ground cover allowed by the sunlight reaching the forest floor ,creates many different habitats for wildlife, adding plant and animal diversity to the landscape. Related Communities: Grades into Oak-Pine-Hickory Forest, or Acidic Glades and Barrens community. |
