Orconectes cooperi has been assessed as Least Concern. This species has a relatively small range and is restricted to a single river basin, however there are no known threats to this species, which inhabits a relatively rural area. Expansion of the Huntsville metropolitan area could potentially lead to impacts from urbanization in the future. Consequently, monitoring of the growth of this urban centre and its subsequent impacts on the species is recommended. Further research is required to determine the abundance of this species, and to what extent it is impacted upon by threats within its range.
|Range Description:||This species was first found at the Brier Fork of the
It is known from only 7 localities, primarily in the Flint River (Tennessee system) in Madison County, Alabama (Mirarchi et al. 2004, Schuster and Taylor 2004, Schuster et al. 2008) and Lincoln County, Tennessee. In Tennessee, Williams and Bivens (2001) documented it in the Highland Rim province in the headwaters of the Flint River system in Lincoln County. This species has a distribution of approximately 2539 km2.
Native:United States (Alabama, Tennessee)

|Population:||There is no population information available for this species.|
|Habitat and Ecology:||This species is found in stream habitats, most commonly along the edges amongst leaf litter (Cooper and Hobbs 1980). The streams in which it has been found support a wide variety of crayfish species due to high levels of habitat heterogeneity (Cooper and Hobbs 1980). Furthermore, these streams get much deeper during flooding in winter and spring (Cooper and Hobbs 1980).|
There are no known major threats impacting this species. This species inhabits a rural area, however, urbanization of the growing Huntsville metropolitan area may impact the species in the future (S. Adams, G. Schuster and C. Taylor pers. comm. 2009).
There are no species-specific conservation measures in place for this species. This species has been given a NatureServe Global Heritage Status Rank of G1, and was assigned an American Fisheries Society Status of Endangered based on its restricted range (Taylor et al. 2007, NatureServe 2009). Further research is required to determine the abundance of this species, and to what extent it is impacted upon by threats within its range.
