Its natural habitats are freshwater springs, spring runs, and wet caves of the Buttercup karst system. Cave dwelling E. tonkawae may represent a distinct species, however further work is needed to clarify their taxonomic status.Conservation status
Eurycea tonkawae is threatened by habitat loss and habitat degradation due to rapid urban growth. In August, 2013, this species was listed as endangered under the Endangered Species Act of 1973.
