Park Species Detail: Wiegand, 2001b: A previously reported occurrence for Riverbank goldenrod (Solidago simplex var racemosa), listed as a highly rare plant species in D.C., was successfully updated during 1999-2000 field surveys. Scattered small groups and individual plants of the rare goldenrod were growing on scoured bare rock and overwash savanna along the river Total population is at least several hundred plants, but no official count was made. Suitable habitat for riverbank goldenrod is abundant in the vicinity, so this occurrence could be more extensive than reported here.Status surveys for this species are recommended to fully determine its current status at Chain Bridge Flats Survey Site.
