Cumberland Plateau/Ridge & Valley Dry Calcareous Forests
|
Dry calcareous forests are unusual hardwood forests that grow in dry to somewhat dry soils. They occur over limestone on valley floors and lower slopes. Glade-like outcroppings appear occasionally within the forests. While similar to oak dominated forests over more acidic soils, these special forests support unique plant assemblages that flourish on the high calcium soils on these lower slopes, and are missing the heath component that is often present in Georgia forests.

Indicator and representative species: calcium-loving species, such as Chinquapin oak, Shumard oak, chalk maple, eastern red cedar, many elms, hackberries, and hickories, white ash, redbud, Carolina buckthorn, coralberry, fragrant sumac, dwarf larkspur, nettleleaf sage, and nettleleaf noseburn.
What's special: In Georgia, deciduous forests growing on calcareous soils are unusual, adding important diversity. The plant communities here are very different from the somewhat acidic oak-pine-hickory communities that are far more common in Georgia.
Related communities: Can grade into calcareous (cedar glades) in rocky openings.
