This cactus is listed on CITES Appendix I, but the laws governing imports in the countries of destination need to be enforced. It does not occur in any protected area.
The species is legally protected in Mexico by the national list of species at risk of extinction, NOM-059-SEMARNAT-2010, where it is listed under the category “threatened” (A; SEMARNAT 2010).
It is widely propagated. The Cadereyta Regional Botanic Gardens has developed a universal technique to reproduce species of the genus Turbinicarpus (including Gymnocactus), with a rate of 5x/4 weeks and 95% soil adaptation success (E. Sánchez pers. comm. 2011).
