|Scientific Name:||Etheostoma etnieri|
|Species Authority:||Bouchard, 1977|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Smith, K. & Darwall, W.R.T.|
|Facilitator/Compiler(s):||Hammerson, G.A. & Ormes, M.|
Somewhat small extent of occurrence, but listed as Least Concern in view of the fairly large number of subpopulations locally common abundance, apparently stable trend, and lack of major threats.
|Range Description:||Range includes the upper Caney Fork system of the Cumberland River drainage, central Tennessee (Page and Burr 2011). The species is limited to streams flowing over limestones of the Mississippian Eastern Highland Rim; it does not occur in cool, slightly acidic headwaters nor from the lower portion of Caney Fork River system (Etnier and Starnes 1993). The range includes the following five counties; White, Putnam, Warren, Van Buren, and Grundy (Hicks 1990).|

|Population:||Historically this species was documented from 11 streams; during a 1988–1989 survey, 19 widely distributed populations were recorded from 18 streams, including five historical locations and seven new locations; extirpated from three historical locations (Hicks 1990). Etnier and Starnes (1993) mapped about 24 collection sites.|
Total adult population size is unknown. The species is locally common (Page and Burr 1991), common in large cool streams (Etnier and Starnes 1993). Hicks (1990) stated that populations were small.
Stable, but relatively restricted; many populations are isolated by impoundments (P. Shute, pers. comm., 1997). No immediate danger of extinction, most present populations are small (Hicks 1990).
|Current Population Trend:||Stable|
|Habitat and Ecology:||This darter typically occurs in gravel riffles in creeks and small rivers, also in vicinity of springs, in bedrock pools, and in shallow margins of riffles in Caney Fork and its major tributaries; it is common in gravel shoal areas of cool medium-sized creeks to large rivers; avoid tiny creeks (Etnier and Starnes 1993, Page and Burr 2011).|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||No current threats are known (Etnier and Starnes 1993; Mel Warren, pers. comm. 1999). The major potential threat is habitat degradation due to chemical runoff from agriculture, siltation, and in some cases mining effluents (Hicks 1990). Habitat is easily disturbed by siltation and water quality degradation due to chemical runoff from agriculture and urbanization (P. Shute, pers. comm., 1997).|
|Conservation Actions:||Currently, this species is of relatively low conservation concern and does not require significant additional protection or major management, monitoring, or research action.|
