Fusconaia ozarkensis has been assessed as Least Concern as it is fairly widespread in the Ozark Highlands, but has experienced some extirpations historically at the edge of its range in parts of Missouri and in Iowa. Monitoring of population trends would ensure that any significant changes in the status of this species will be responded to adequately.
|Previously published Red List assessments:|
|Range Description:||In Missouri, the species is restricted to the southern Ozarks including the James, North Fork White, Eleven Point, and Current Rivers, all of which flow south. In addition, it has been found in an archaeology site in Camden Co. in a north-flowing river, the Sac (Oesch 1995) as well as the Spring River in southwestern Missouri (Branson 1982). In Arkansas, it is fairly widespread across the White and Arkansas River basins in the northern part of the state in the Ozark Highlands. It is extirpated in Iowa where it formerly occurred in the Sac County region of the Sac River basin. Occurrence in Oklahoma is speculative although it is very close in Missouri.|

|Population:||In Missouri, this species is restricted to the southern Ozarks and has been found in the James, the North Fork White, the Eleven Point and the Current Rivers (Oesch 1995). It is widespread in the Arkansas Ozark Highlands in the White and Arkansas River basins (including Buffalo River). Occurrence in Oklahoma is speculative although it is very close in Missouri.|
Historically, some extirpations have occurred at the edges of the range of this species in Missouri (Oesch 1995) and it is now extirpated from Iowa where it formerly occurred in Sac Co.
|Current Population Trend:||Stable|
|Habitat and Ecology:||Optimally this species occurs in medium to large headwater streams, preferably in riffle or run areas but sometimes in glide or pools.|
|Congregatory:||Congregatory (and dispersive)|
|Major Threat(s):||Typical threats in the Ozark region include habitat destruction (channel alteration, channel maintenance), hydrological alterations (dams), and nutrient loading (confined animal operations, grazing).|
|Conservation Actions:||No widespread conservation actions have been undertaken. Monitoring of population trends would ensure that any significant changes in the status of this species will be responded to adequately.|
