Geographic Range [top]

Range Description:The Blotchside Logperch is widely but disjunctly distributed in mountains and uplands of the Tennessee (generally rare) and Cumberland (probably extirpated) river drainages, Virginia, North Carolina, Alabama, Tennessee, Georgia, and (at least formerly) Kentucky (Jenkins and Zorach in Lee et al. 1980, Burr and Warren 1986, Menhinick 1991, Etnier and Starnes 1993, Jenkins and Burkhead 1994, Boschung and Mayden 2004, Page and Burr 2011).

In the Tennessee drainage, records extend from the upper Tennessee drainage in Virginia and North Carolina downstream through the Duck and Buffalo rivers, and in Whiteoak Creek, slightly below the mouth of the Duck River, Tennessee. The species is consistently collected in portions of the Little and Duck rivers in Tennessee and in the North Fork Holston and Copper Creek in Virginia (Etnier and Starnes 1993). In the Cumberland drainage, records are available from the Little South Fork and from the Wolf and Obey rivers, but apparently there are no recent records from anywhere in the Cumberland River drainage (Etnier and Starnes (1993).

In Virginia, Percina burtoni occurs in the North Fork of Holston River (apparently increasing range and/or abundance in the 1980s), the lower section of Laurel Creek, and the Clinch River-Copper Creek-Little River system (Burkhead and Jenkins 1991, Jenkins and Burkhead 1994).

In Tennessee, recent records are from Whiteoak Creek in Houston County, the Duck and Buffalo rivers, Butler Creek in Wayne County, Spring Creek, tributary to the Hiwassee River, the Little River, in Blount County, and Big Creek (Holston River tributary) in Hawkins County; populations are extremely localized and widely scattered.

In Alabama, the species has been found in the Tennessee River drainage, in Little Butler Creek (tributary of Shoal Creek) (and extending into Tennessee) and in Larkin Fork of the Paint Rock River system (Boschung and Mayden 2004).

Population [top]

Population:This species is known from several dozen localities (some closely adjacent in the same river) that may represent roughly a couple dozen distinct occurrences (subpopulations).

Total adult population size is unknown. Populations generally have low densities (Jenkins and Zorach, in Lee et al. 1980), perhaps naturally so (Jenkins and Burkhead 1994). This species is uncommon or rare in all extant populations (Jenkins and Burkhead 1994), but it is not easy to capture, and both abundance and distribution may be slightly greater than available records indicate (Etnier and Starnes 1993). However, even snorkelling surveys in prime occupied habitat may yield few observations (Jenkins and Burkhead 1994).

This species is apparently extirpated in the Cumberland River drainage, and some populations in the Tennessee River drainage have apparently been extirpated (Jenkins and Zorach in Lee et al. 1980, Etnier and Starnes 1993, Jenkins and Burkhead 1994, Boschung and Mayden 2004).

Jenkins and Burkhead (1994) noted that this species appears to have recently expanded its range or locally increased its population density in the North Fork Holston River in Virginia.

Trend over the past 10 years or three generations is uncertain but probably relatively stable or slowly declining. Three generations span roughly 10 years or less.
Current Population Trend:Unknown

Habitat and Ecology [top]

Habitat and Ecology:Habitat includes gravel runs and riffles of clear, small to medium rivers (Page Burr 2011), or primarily large creeks and small to medium rivers with moderate gradient and usually clear water; substrates vary but usually consist of gravel and boulders, cobble, or rubble lacking major siltation (Jenkins and Zorach in Lee et al. 1980, Boschung and Mayden 2004). In Virginia, Blotchside Logperches occurred mainly in slow runs and pools, adults and larger juveniles occupied riffles and runs and occasionally pools (Burkhead and Jenkins 1991). This species usually avoids turbid water and silty substrates (Boschung and Mayden 2004), and it apparently is intolerant of reservoir conditions (Burkhead and Jenkins 1991). Spawning occurs probably on loose clean gravel in moderate to strong flow (Burkhead and Jenkins 1991, Jenkins and Burkhead 1994).
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: This species is not utilized.

Threats [top]

Major Threat(s): This species is probably detrimentally affected by siltation, turbidity, chemical pollution, and impoundment (Burkhead and Jenkins 1991). Warren et al. (2000) categorized this species as "vulnerable." Jelks et al. (2008) rated it as "threatened", based on present or threatened destruction, modification, or reduction of habitat or range.

Conservation Actions [top]

Conservation Actions: Better information is needed on life history, current abundance and distribution.

This species would benefit from land management that reduces siltation (Burkhead and Jenkins 1991).
