Peatland Forests and Shrublands
Coastal Plain Wet Acidic Shrublands
General Description This habitat includes a number of co-adapted complexes consisting of various wetland species of heaths, hollies, and other shrub species along with their obligate herbivores.

The physical factors that determine the presence of the shrubs include a high water table, producing constantly saturated, wet soils; acidic, nutrient poor soil types; and periodic fires. The largest expanses of these habitats occur on wet flats in the Outer Coastal Plain. In the Sandhills, they include seepage slopes, streamhead forests, and the ecotones between these wetlands and the adjoining drier Longleaf-dominated habitats. For the herbivores, the main habitat requirement is the presence of their larval host plants. Those that pupate on the ground must be able to cope with the prevailing soil and water conditions, but others may spend their entire lives up in the shrubs.

Other MSD Habitats that intersect this habitat type include Laurel Shrublands, General Heath Thickets, and General Shrublands and Thickets. All of those habitats contain species that are common in the peatlands and other acidic wetlands that characterize Coastal Plain Wet Acidic Shrublands; the members of the General Shrublands and Thickets group, in fact, may be the most prominent vertebrates in this habitat. However, all of the members of these intersecting habitats occupy a much wider range, including areas of uplands as well as wetlands associated with rich soils.
