Range Extent250-20,000 square km (about 100-8000 square miles)
Number of Occurrences81 to >300
Rank Reasons
Rare throughout a significant portion of its range. Locally frequent in the New Jersey Pine Barrens (with scores of occurrences), as well as Maryland and Delaware. No extant sites known in Pennsylvania or North Carolina.
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.
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.
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).
Ecology & Habitat

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

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.
