NatureServe Global Conservation Status Factors

Range Extent Comments: Atlantic Coastal Plain from Connecticut and Long Island (New York) south to Georgia and Alabama, most abundant in New Jersey, Delaware, and Maryland. Also in southern Appalachians.

Number of Occurrences: 81 to >300
Number of Occurrences Comments: Locally abundant in New Jersey Pine Barrens, and locally frequent in Maryland and Delaware (as of 2000). Rare in other states in range.

Population Size Comments: Apparently rare or uncommon throughout its range except for the NJ Pine Barrens where it is locally abundant.

Overall Threat Impact Comments: Land-use conversion, (drainage of habitat) habitat fragmentation, and bog succession are moderate threats to this species (Southern Appalachian Species Viability Project 2002).

Short-term Trend: Decline of 10-30%

Ecology & Life History
Help
General Description: Barratt's sedge is a loosely clumped grass-like perennial that occurs in patches. Its roots are fuzzy and yellow. Leaves are strap-like, 2-5 mm wide, and curled under on the edges. Stems are 20-90 cm tall and much exceed the leaves. At the apex of the stems are narrowly cylindrical clusters of male flowers. Also towards the apex of the stems are 2-4 secondary stems which branch off of the main stems. At the apex of these secondary stems are cylindrical flower/fruit clusters (spikes). Usually these spikes are mostly composed of densely arranged female flowers with a few male flowers towards the apex of the spikes. The female flowers develop into fruits (perigynia) which are 2.5-3.5 mm long (Mackenzie 1931-1935, Ball 2002).
Habitat Comments: Wet swales, stream banks, and savannas, especially in pine barren swamps. Also occurs in disturbed habitats like ditches, abandoned cranberry bogs, and railroad, powerline, and road ROW's.
