This species has been propagated and made widely available for many years. 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). The only known locality is not in a protected area.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).|
