Prairies and Savannas (Upland).Prairies are expanses of grasses, forbs, and shrubs that grow on deeper soils than those of glades and barrens. Savannas have a few scattered trees. Most Piedmont prairies and savannas are kept open by mowing or fire; without them, trees will eventually dominate. Prairies often develop in "old fields" in the first two decades after agricultural land or logging sites are abandoned, in a procession called "succession". During the first phases of succession, grasses, wildflowers and shrubs grow in, followed in later phases by trees.
Prairies, sometimes stretching for long distances, were more widespread in the past, when native Americans set fire to preserve them. Ecologists have concluded that for thousands of years, fire has been an important element in maintaining biodiversity on the landscape. |
Landscapes
What's special: Grasslands support many pollinators, including bees, butterflies, moths, and many other beneficial insects, which form the foundation of food chains, and are essential for sustaining natural landscapes. Birds and small mammals find food and shelter in prairies.
Conservation: It is a high priority in Georgia to restore and maintain prairies through prescribed fire, and planting prairie species under powerlines, where they are often maintained by mowing Related to: Grades into Glades and Barrens on thin soils with rock outcrops, and into Pine-Oak Woodlands as trees become denser. Grades to Wet Meadows in moister sites. |
