Park Species Detail: Wiegand, 2001b: A previously reported occurrence for Prairie cordgrass (Spartina pectinata), listed as a highly rare plant species in D.C., was successfully updated during 1999-2000 field surveys. Scattered large clumps of prairie cordgrass were growing in moist silt and sand among cobbles and rocks in shoreline and low prairie habitats. The plants were scattered for several hundred meters along and near the edge of the river, This area floods annually during seasonal high water in winter and spring, and following up river storm events. Suitable habitat for prairie cordgrass is abundant in the vicinity, so this occurrence could be more extensive than reported here.Status surveys for this species are highly recommended to fully determine its current status at Chain Bridge Flats Survey Site. Found at 1 site. A Highly Rare plant species known to occur within the District of Columbia portion of LOCO (along the C&O Canal NHP and Potomac River from the Maryland line to Key Bridge, Washington, D.C.), Park Species Data Source: TNC, 1999;Wiegand, 2001b
