Southern Backswamps

Ecoregion in LA, MS

Generate High-Quality PDF

The Southern Backswamps ecoregion is generally warmer, has a longer frost free period, and has more precipitation than the Northern Backswamps (73d). Similar to 73d, soils are mostly poorly drained, clayey Vertisols, rich in organic matter. Wetlands are common and flooding occurs frequently. Bottomland hardwood forests are more prevalent in this region than in the adjacent Southern Holocene Meander Belts (73k), where cropland is common. Channelization and flood control systems have modified this region and impacted many of the wetland habitats.
