HABITAT DESCRIPTION: |
|
Found in small and medium sized streams of the coastal plain from the fall line to the just above the tidewaters (Martof et al. 1980). They thrive in larger aquatic sites of cypress and tupelo. They are not known to travel over land so movement is apparently restricted to waterway corridors. NATURE SERVE GLOBAL HABITAT COMMENTS: Bottoms of
slow, sand- or mud-bottomed streams and connected ditches, cypress swamps; also stream-fed rice fields and mill ponds. Favors bottoms with leaf litter and detritus. Juveniles burrow into bottom. Adults congregate in leaf beds in winter. Eggs probably are attached to undersides of objects in water.

NC Natural Heritage Program Equivalent |
380 | Coastal Plain Fresh Water Emergent
|
Emergent vegetation in fresh water seepage bogs, ponds and riverbeds of the coastal plain. Includes alliances dominated by sedges, eelgrass, as well as cane found in unforested cane-brakes.
|
Small Depression Pond, Sandhill Seep, Floodplain Pool, Unforested Floodplain Canebrake, Riverscour Prairies, Vernal Pools
|
50 | Coastal Plain Mixed Bottomland Forests
|
Includes forests dominated by a variety of hardwood species, including sweetgum, cottonwood, red maple.
|
Coastal Plain Bottomland Hardwood (in part), Coastal Plain Levee Forest
|
49 | Coastal Plain Oak Bottomland Forest
|
Bottomland forests dominated by deciduous oak alliances. Oaks represented can include swamp chestnut, cherrybark, willow, and/or overcup oak. Inclusions of loblolly pine temporarily flooded forests occur in patches. Hydrology is temporarily to seasonally flooded.
|
Coastal Plain Bottomland Hardwoods (in part) blackwater subtype, brownwater subtype
|
30 | Cypress-Gum Floodplain Forests
|
Swamps dominated by black or swamp tupelo with or without Taxodium. Seasonally to semi-permanently flooded hydrology.
|
Cypress-Gum Swamps
|
78 | Pond-Cypress - Gum Swamps, Savannas and Lakeshores
|
Cypress dominated swamps and lakeshores. Can include bays dominated by pond cypress or shorelines of coastal plain lakes with a narrow band of cypress.
|
Non-riverine Swamp Forest, Natural Lakeshores (in part)
|
385 | Oak Bottomland Forest and Swamp Forest
|
The swamp chestnut oak, cherrybark oak, shumard oak and sweetgum alliance is one representative. Other alliances are dominated by water, willow, and overcup oaks. Swamp forests can be dominated by sweetgum, red maple, and black gum being dominant.
Loblolly can occur in combination with sweetgum and red maple, or with tulip poplar. Includes saturated and semi- to permanently flooded forests in the mountains.
|
Piedmont/Mountain Bottomland Forest, Piedmont/Mountain Swamp Forest
|
238 | Piedmont/Mountain Submerged Aquatic Vegetation
|
Seasonally to permanently flooded areas with aquatic vegetation. Waterlily, pondweed, hydrilla smartweed are a few of the species that can occur.
|
Piedmont/Mountain Semipermanent Impoundment (in part)
|
239 | Piedmont/Mountain Emergent Vegetation
|
Emergent vegetation of all wetland hydrologies. Sites would commonly support species such as tussock sedge, rushs, and cattail alliances.
|
Rocky Bar and Shore (in part)
|
269 | Floodplain Wet Shrublands
|
Saturated shrublands of the Piedmont, includes buttonbush, swamp-loosestrife, decodon and alders.
|
Piedmont/mountain Semipermanent Impoundment
|
384 | Piedmont/Mountain Mixed Bottomland Hardwood Forests
|
Includes temporarily to seasonally forests dominated by hardwood species. Hardwoods include sweetgum, red maple, sycamore which co-occur in a mosaic of bottomland and levee positions. Includes alluvial hardwood forests in the mountains. Hemlock and white pine may occur as inclusions, but are generally mapped separately.
