Records dating back to 1885 indicate that the historical range of the candy darter is limited to the Gauley and greater New River watersheds in West Virginia and Virginia (but not extending into the New River watershed in North Carolina).</div><div><br /></div><div>The candy darter is not confirmed to occur in the Lower New River watershed; however, the best available data suggest that the species did likely occupy this watershed. Because the Lower New River watershed is geographically positioned between the Middle New and Greenbrier River watersheds (upstream) and the Gauley River watershed (downstream), each of which have confirmed candy darter populations and suitable habitat, it is reasonable to conclude that the species likely occurred in the Lower New River watershed.</div><div><br /></div><div>The factors supporting the candy darter having been more abundant and widely distributed within its range than indicated by post industrialization surveys include: (1) the geographical distribution and historical connectedness of known candy darter streams; (2) the diversity of habitat conditions (e.g., stream size, gradient, and water temperatures) associated with all known candy darter occurrences; (3) high candy darter abundance and continuity documented in some streams with high quality habitat; and (4) severe degradation of aquatic habitat conditions and declines in fish abundance prior to comprehensive fish surveys. Together these factors support the conclusion that the candy darter was likely more widely distributed and abundant throughout its historical range where suitable habitat (described above) existed.</div>
