Fallicambarus gilpini has been assessed as Near Threatened. This species has an estimated extent of occurrence of approximately 3,800 km2 and is only known from eight separate sites. At present there is no known evidence that it is declining, or being impacted by any significant threats so does not quite meet the criteria for Vulnerable. Further research on the abundance and possible threats for this species is needed to ensure this species does not warrant listing in a threat category.

Habitat destruction and degradation are the main threats to all Fallicambarus crayfishes (NatureServe 2009). The more widely distributed species can be vulnerable to loss of suitable habitats or habitat fragmentation at range edges; as well as habitat modification for agriculture and wetland destruction. In addition, competition from introduced crayfish species (Orconectes rusticus, Procambarus clarkii, Cambarus robustus) is considered a threat to the species in the genus Fallicambarus (Guiasu 2007, NatureServe 2009). However these are general threats to all Fallicambarus species; the precise threats to this species are unknown.
This species has been given a NatureServe Global Heritage Status Rank of G2, 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.
