Cumberland Plateau/Ridge & Valley Calcareous Glades & Barrens (Cedar Glades)
|
|
These are rocky, non-forested areas that have many limestone outcroppings and expanses of shallow, gravelly soils. The vegetation is usually a mosaic of herbaceous areas, shrubs, bare rock, and widely spaced, stunted trees. Eastern red cedar is common, so these communities are often called Cedar Glades.
Indicator species: eastern red cedar in the midst of flat outcroppings of limestone. What's special: Expanses of exposed limestone are rare in Georgia and so this community contains a number of rare, endemic species, including least glade cress, purple tassels, Nashville breadroot, and Eggleston's violet, as well as species that are more common farther west. Related to: Grades into dry calcareous forest as soil deepens over the limestone substrate and if fire becomes less common. This community also overlaps strongly with the Calcareous Prairies natural community; however, the prairies will have more extensive areas of deeper soil, and fewer limestone outcroppings. |
