Number of Occurrences21 to >300
Rank ReasonsValeriana pauciflora is common now but possibly threatened in the long-term by clearcutting of mesic hardwood forest habitats. It may also be severely threatened by invasion of garlic mustard, especially in eastern forests.
Range Extent CommentsValeriana pauciflora occurs from Pennsylvania and Delaware west to Illinois and south to Virginia, Tennesee, and Alabama.
Occurrences Comments5 extant EOs in Virginia; common and not tracked in Illinois (16 cos.), Kentucky, and West Virginia.
Threat Impact CommentsV. pauciflora is threatened primarily by clearcut logging of floodplain hardwood forests, from which the herbaceous layer often does not recover. Also threatening is invasion by exotic plant species, such as Alliaria petiolata (garlic mustard) and Lonicera japonica (Japanese honeysuckle). Garlic mustard has replaced the native flora in many eastern bottomland forests (Ludwig pers. comm. 1995). Unauthorized equestrian/ATV use poses a threat due to trampling of plants.
