Fallicambarus harpi has been assessed as Near Threatened. This species has an estimated extent of occurrence of 4,000 km2 and faces a number of threats including habitat degradation, and competition from invasive species. However, it is unclear if its distribution is severely fragmented and number of locations is likely to number greater than 10. Further research is needed on the spread of threats as invasive species may be widespread across this species range, and therefore lower the number of known locations. This would result in listing this species in a higher threat category.
|Range Description:||This species was known from only two localities, both in the Ouachita River basin in Pike County, Arkansas (Hobbs and Robison 1985). However, it is now known to occur in 12 sites in Garland, Hot Spring, Montgomery, and Pike counties (Robison and Crump 2004, Robison et al. 2008). This species has a distribution of approximately 4,000 km2.|

|Habitat and Ecology:||This species is a primary burrower, located in low lying seepage areas in pastures, yards and lawns (US Forest Service 2008).|
Habitat destruction and degradation are the main threats to all Fallicambarus crayfishes (NatureServe 2009). Also, 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. The second greatest threat is pollution (including air, water and soil pollution as these species spend time burrowing and in temporary waters). Because burrowing crayfish tend to prefer warmer climates and the milder and shorter winters currently found in southeastern areas of the
There are no species-specific conservation measures in place for this species. 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 whether it is being impacted upon by any major threat processes.
