Threat ImpactVery high - high
Range Extent200,000-2,500,000 square km (about 80,000-1,000,000 square miles)
Number of Occurrences81 to >300
Rank ReasonsFairly large range primarily in the southeastern U.S. and southern Great Lakes states; populations have been reduced or eliminated in some areas due to habitat alteration (e.g., siltation) caused by agricultural practices; secure throughout at least 50% of the range.
Range Extent CommentsRange includes the North American Atlantic Slope from southeastern Virginia to southern Florida, and Gulf Slope drainages from southern Florida (Charlotte Harbor) to the Brazos River, Texas; Great Lakes and Mississippi River basin lowlands from southern Ontario to Wisconsin and south to the Gulf; sporadic in the north, common on the lower Coastal Plain (Page and Burr 2011).
Occurrences CommentsLee et al. (1980) mapped hundreds of collection sites that represent at least 100 distinct occurrences. Likely there are at least 100 extant occurrences. Trautman (1981) mapped 6 collection sites in Ohio for the period 1955-1980. Smith (1979) mapped about two dozen post-1950 collection sites in Illinois; these encompassed about 6 distinct clusters of sites. Burr and Warren (1986) mapped 16 collection sites in Kentucky; these represent perhaps 14 distinct occurrences.
Threat Impact CommentsPopulations apparently have declined in areas subject to siltation (Lee et al. 1980). In Tennessee, this species is perhaps extirpated from many habitats altered by agricultural practices (Etnier and Starnes 1993). Almost certainly it was more abundant in the Lowlands region of southeastern Missouri before that region was ditched and drained (Pflieger 1997). A decline in abundance in Arkansas likely has occurred due to large-scale clearing of land throughout the Delta region (Robison and Buchanan 1988). Threats in Canada include siltation and drainage of limited habitat (Mandrak and Crossman 1996). Burr and Warren (1986) recommended a status of "threatened" in Kentucky and implied that water acidification from mining was a threat (Burr and Warren 1986:366).
