Threat ImpactMedium
Range Extent1000-5000 square km (about 400-2000 square miles)
Number of Occurrences6 - 20
Rank ReasonsSmall range in the upper James River drainage, Virginia; generally uncommon; threats include degradation of habitat by impoundment and pulp mill effluents and competition with apparently recently introduced Notropis telescopus.
Range Extent CommentsRange includes the Ridge and Valley Province of the upper James River drainage, Virginia; this species has the smallest range of the three fishes endemic to the James drainage (Burkhead and Jenkins 1991, Jenkins and Burkhead 1994).
Occurrences CommentsJenkins and Burkhead (1994) mapped about 38 collection sites, which may represent several distinct occurrences (subpopulations) and perhaps not more than 10 locations (as defined by IUCN).
Threat Impact CommentsImpoundment, including cold tailwater, and pulp mill effluents present slight or moderate threats to the habitat. These already have altered quality of the habitat in the Jackson River and upper James River. The roughhead shiner may be threatened by competition from the apparently recently introduced, rapidly spreading telescope shiner, Notropis telescopus (Burkhead and Jenkins 1991, Jenkins and Burkhead 1994).
