The dominant vegetation in the Coastal Plains consists of pine forests and marshes.

Pine trees, such as longleaf and loblolly pines, thrive in the sandy soils of the region, forming dense forests. In wetter, low-lying areas, marshes and swamps are common, featuring grasses, shrubs, and water-tolerant plants like cattails and cypress trees. This combination of pine forests and wetlands creates a diverse habitat that supports a wide variety of wildlife. The Coastal Plains' vegetation plays a vital role in maintaining soil stability, preventing erosion, and contributing to the region’s overall ecological health.
