|Scientific Name:||Etheostoma striatulum|
|Species Authority:||Page & Braasch, 1977|
|Red List Category & Criteria:||Vulnerable B1ab(iii)+2ab(iii); D2 ver 3.1|
|Reviewer(s):||Smith, K. & Darwall, W.R.T.|
|Facilitator/Compiler(s):||Hammerson, G.A. & Ormes, M.|
Listed as Vulnerable because extent of occurrences is less than 5000 sq km, area of occupancy may be less than 20 sq km, number of known locations does not exceed 10, and habitat quality is declining.
|Range Description:||This species' range is confined to small tributaries of Duck River, Tennessee River drainage; Bedford, Coffee, Lewis, Marshall, and Maury counties, central Tennessee (Etnier and Starnes 1993, Burr et al. 1993, Page and Burr 2011).|

Of 28 known collection localities, Burr et al. (1993) found the species in 10 locations representing probably 9 distinct subpopulations. Etnier and Starnes (1993) reported that this species occurs in fewer than a dozen creeks.
Total adult population size is unknown. Reported to be generally rare by Page (1980) and Page and Burr (2011); uncommon (Etnier and Starnes 1993).
Etnier and Starnes (1993) reported that efforts to collect this species in four of the fewer than a dozen creeks from which the species is known were not successful. Burr et al. (1993) found this species in only 10 of the 28 historical collection localities.
Current trend is not definitely known, but habitat extent and quality are probably still declining.
|Habitat and Ecology:||This darter occurs in bedrock pools of low-gradient headwaters and creeks having large slab stones (Page 1980, Etnier and Starnes 1993, Page and Burr 2011). Adults use stones for cover and also may shelter under cut banks and tree roots. Small individuals occur in gravel-bottomed pools and along vegetated or rocky stream margins. Eggs are laid on underside of large slab stone (Page 1983).|
|Major Threat(s):||Habitat degradation resulting from agricultural practices pose the greatest threat to this species. Cattle manure being dropped directly into streams is causing severe oxygen depletion. Siltation from nonpoint agricultural sources is also a problem (D. Etnier pers. comm. 1995).|
|Conservation Actions:||Physical and chemical habitat requirements need to be studied. Occurrences should be sought in suitable habitats throughout range. Management agreements should be made with local farmers and ranchers.|
