NatureServe Global Conservation Status Factors

Range Extent Comments: Occurs in Virginia (though this state has ranked it as a false report), North Carolina (Bladen, New Hanover, Craven, Brunswick, Onslow, Carteret, Gates, Jones, Columbus, Pender counties), South Carolina, Tennessee, and Florida. Potentially in Georgia, but no actual reports from this state.

Number of Occurrences:  
Number of Occurrences Comments: Over 20 occurrences in North Carolina; 18 occurrences in Florida as of October/1997; (need numbers from rest of the range).

Overall Threat Impact Comments: Probably eliminated by intensive site preparation or careless harvest for timber management, erosion or heavy grazing; impacts to small stream habitat (runoff, channelization).

Intrinsic Vulnerability Comments: Some disturbance by logging such as selective cutting does not affect abundance.

Ecology & Life History

Basic Description: Perennial smooth sedge forming small to large tufts, these increasing by means of slender, spreading rhizomes.
Technical Description: "Culms 1-4 dm tall. Blades 1-6 mm wide. Staminate spike 1-2 cm long, 2-3 mm broad; scales scarious, obtuse to acute. Pistillate spikes 8-18 mm long, 6-8 mm broad. Perigynia glaucous-green, ellipsoid to slightly obovoid, 3.5-4.5 mm long, 1.3-1.8 mm broad, beaks tapered, slightly excurved; scales scarious, 1.8-4.4 mm long, obtuse to aristate. Nutlets 2-2.2 mm long, 1.5-1.6 mm broad." (Radford et al. 1968)
Diagnostic Characteristics: Carex chapmanii may be characterized by its elongate rhizomes projecting from the culm, its brownish culm bases, and its rather long perigynia with their (usually) outcurved beaks (unpublished material in TNC files).
Duration: PERENNIAL
Terrestrial Habitat(s): Forest - Mixed, Forest/Woodland
Habitat Comments: Well-drained hammock woodlands, sandy hammocks; in beech-magnolia-maple with some oak-pine; floodplains of blackwater streams with intermittent floods of brief duration. Associated with blackgum, swamp cypress, tuliptree, red maple, sweetgum, Florida maple, water oak, and loblolly pine (U93LEB01HQUS).
