Procambarus reimeri has been assessed as Data Deficient. This species has an extent of occurrence of less than 100 km2 , and occurs in six localities. However, no major threats have been identified. Though, due to this species' restricted range and low population abundance, it is susceptible to any event which will cause habitat degradation. Further research is required to determine the abundance of this species, and to what extent it is impacted upon by threats within its range. If with further research this species is found to be impacted upon by a major threat process, it will qualify for uplisting to Endangered under criterion B.
Previously published Red List assessments:

Systems: Freshwater

Threats [top]

Major Threat(s): As this is a burrowing crayfish in a limited area, it is susceptible to habitat degradation coupled with the potential for such degradation throughout its range (Crandall et al. 2009)

Conservation Actions [top]

Conservation Actions:

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 and ongoing habitat degradation (Taylor et al. 2007, NatureServe 2009). Further research is on the threats to this species.
