Habitats of North Carolina

Lentic Habitats
Coastal Plain Herbaceous Ponds and Sloughs

Habitat Overview

This habitat includes permanent ponds and sloughs in the Coastal Plain that support dense masses of floating and submerged aquatic plants. Many of the sites occupied by this habitat represent natural depression ponds, including Carolina Bays, limesink ponds, and interdune ponds. Also included are beaver ponds, old mill ponds, borrow pits, and other shallow man-made ponds. This particular habitat is limited to the Coastal Plain, with the Determining Species found only or predominately in that region. The General Herbaceous Ponds habitat intersects with this habitat but also extends across the Piedmont and into the Mountains.

All of these habitats are open and very sunny, a critical factor for the high diversity of aquatic plants that are the Determining Species of this habitat. Swamp forests generally do not have enough insolation to support a high biomass of aquatic plants and are therefore not included. The Coastal Plain Sluggish Waters habitat intersects this habitat but also intersects swamp forests and is likewise treated separately.

Animal members of this habitat include herbivores such as the turtles and several moth species that have aquatic larvae that specialize on the plant members of this habitat. Also included are amphibious predators, such as the Dragonflies and Damselflies, that are adapted as nymphs to foraging within the submerged vegetation and as adults to hunting from perches on the emerged portions.
