While inland freshwater aquatic systems represent a small percentage of the landscape, they are living systems that are influenced by numerous conditions such as landscape position, slope, width, depth, temperature, velocity, substrate or bed material, chemistry, and land cover. The various geology, landscape, and climate attributes found in North Carolina contribute to the wide diversity of aquatic habitats found across the state. The following table provides an overview of the type of natural aquatic communities found in North Carolina and the ecoregions where they occur.
