Procambarus alleni has been assessed as Least Concern. This species occupies a broad geographic range and is found in a range of habitat types. It is robust and tolerant of seasonal water conditions. While there has been a historical decline in this species, population numbers are stable at present and there are plans to restore the hydrology within some of its habitat. Further research is required to determine the abundance of this species, and to what extent it is impacted upon by threats within its range.

This species is found in East of St. Johns River, throughout peninsular Florida, in and South of Levy and Marion Counties, as well as on some of the Keys (K. Crandall pers. comm. 2009). This species has a distribution of approximately 80000 km².

This is a common species within the everglades (Acosta and Perry 2000). Though, as a result of anthropogenic impacts such as water management, there has been an increase in dry seasons which has resulted in increased mortality of this species (Acosta and Perry 2000).

This species is found in both permanent lentic and lotic situations such as ditches, marshes and lakes, and is a secondary burrower (Hobbs 1989). Acosta and Perry (2000) suggest that this species is one of the most ubiquitous inhabitants of the seasonally flooded marl prairies wetlands of the eastern Everglades. Hobbs (1989) indicates that this species is tolerant of a wide variety of water quality parameters, and also describes this species as 'robust and well-adapted to seasonal habitats'.

The main threat to this species is alterations to the hydrological regime (abstraction of water) of its habitat within the Everglades National Park. A study by Acosta and Perry (2002) found that crayfish density has declined but stabilized, over a period of 20 years to 13% of the saturated population size. There are plans to restore the hydrological regime of the Everglades, and a 7-month hydroperiod would be enough to increase the density of this species by 7 fold (K. Crandall pers. comm. 2009).

This species is sold to the aquarium trade (aqua-terra-vita 2009).

There are no species-specific conservation measures in place for this species. Though, in Florida it is known to occur in Big Cypress National Preserve and the Everglades National Park, where there are plans to restore the hydological conditions. Furthermore, it has been given a NatureServe Global Heritage Status Rank of G4, 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 to what extent it is impacted upon by threats within its range.
