Taxonomic Notes:
There is some taxonomic confusion over whether Elimia plicatastriata is a distinct species, or just a
spring or small creek morph of E. edgariana or E. curreyana (NatureServe 2010).
Assessment Information
Red List Category & Criteria:
Near Threatened ver 3.1
Year Published:
2012
Date Assessed:
March 5, 2012
Justification:
Elimia plicatastriata has been assessed as Near Threatened as it has an extent of occurence of less than
14,000 km2, which would bring it within the category of Vulnerable under criterion B1 as it is likely that
the effects of damming and human transport throughout its range would be causing a continuing
decline of available/suitable habitat and the number of mature individuals. However, details on the
severity of these threats are unknown for this species. Further research is required to identify the status
of the population and the extent of any threats and accurately define the number of locations for the
species, which is currently assumed to be more than ten locations.
Geographic Range
Range Description:
This species is known from Kentucky and Tennessee in the United States. It has been found in the
Cumberland River (several tributaries) and in Big Richland Creek of the Tennessee River (Burch 1989),
and in the Harpeth River below the narrows (Florida Museum of Natural History Museum Records, cited
in NatureServe 2009). The species has an estimated extent of occurrence of less than 14,000 km2.
Although it has quite a localised distribution, the species occurs in many tributaries which are likely to
equate to more than ten locations.

Population
This species has a relatively localised distribution although it is known to occur in a number of areas.
There is no population information available for this species.
Current Population Trend: Unknown
Habitat and Ecology (see Appendix for additional information)
This species is known from rivers, creeks and springs (NatureServe 2009).
Systems: Freshwater
Use and Trade
This species is not utilised.
Threats (see Appendix for additional information)
It is undocumented whether any threats are affecting this species. However, both the Tennessee and the
Cumberland River have many dams and are used for transport, with barges and recreational boats
frequently travelling up- and downstream. Both rivers are polluted which is also likely to be affecting this
species, although it is unknown to what degree. It is found in many tributaries and so threats may be
spread over several subpopulations.
Conservation Actions
Although there is no documented threat or population information, it appears that this species is not
currently considered to be of conservation concern in either Kentucky or Tennessee. This species has
been given a NatureServe Global Heritage Status Rank of G2G3 - Imperilled to Vulnerable (NatureServe
2009).
