The Department of Recreation, Parks & Cultural Activities' Natural Resources Division surveyed the vascular flora of Alexandria from 2000-2016. In addition, the team searched herbaria for historical collections that reflected taxa native to the City. These surveys and collections yielded more than 800 native vascular plants representing 366 genera and 128 families. Currently available is the Flora Project in PDF form, a graphic presentation called "Vanishing Flora of Washington and Vicinity" which introduces the Flora Project, and a map of Alexandria's surface geology. Check back for an upcoming searchable database of flora found in Alexandria.
