Procambarus clarkii has been assessed as Least Concern. This species is abundant and able to tolerate a range of habitat types within its natural range. It is under no imminent threat. Further research is required to determine the abundance of this species, and whether it is being impacted upon by any major threat processes.
|Range Description:||This species is wide-ranging from northern Mexico, to Escambia County in Florida, North to southern Illinois and Ohio. It has been widely introduced in the United States and elsewhere; Huner (1986) recorded the following introductions: Arizona, California, Georgia, Hawaii, Idaho, Indiana, Maryland, North Carolina, Nevada, Ohio, Oregon, South Carolina, Utah and Virginia. This species has also been introduced to Europe, Africa, East Asia, South and Central America (K. Crandall pers. comm. 2009).|

|Population:||"The population at the Granville County site is extremely large, both in numbers and biomass. There is a very dense population distributed throughout the small ponds along Ledge Creek and in shallow areas of the creek itself" (Cooper et al. 1998). This is typical of this species in its native range (K. Crandall pers. comm. 2009).|
|Current Population Trend:||Increasing|
|Habitat and Ecology:||This species is found in a range of habitat types including wet meadows, subterranean karst systems, seasonal swamps and marsh, permanent lakes and streams, rice paddy fields, and irrigation channels and reservoirs (Global Invasive Species Database 2009). This species is able to tolerate a range of environmental conditions including low oxygen levels and high temperatures (Global Invasive Species Database 2009).|
|Use and Trade:||This species is a major commercial crayfish and has been widely introduced into culturing ponds globally (K. Crandall pers. comm. 2009).|
|Major Threat(s):||This species is highly invasive, and is not impacted upon by any threats (K. Crandall 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 G5, and was assigned an American Fisheries Society Status of Currently Stable (Taylor et al. 2007, NatureServe 2009). Further research is required to determine the abundance of this species, and whether it is being impacted upon by any major threat processes.
