Mammillaria crinita is listed as Least Concern due to its large population, extensive subpopulations, and widespread nature with little evidence of decline from human activities. The distinctive form of M. crinita tezontle is highly threatened and requires site level conservation of its very limited range.

Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species grows on volcanic rocks and soil in xerophyllous scrub, open oak (Quercus), and low desert scrub.

Use and Trade [top]

Use and Trade: This species is collected as an ornamental plant for nativity scenes. Some forms are in commercial cultivation for international trade.

Threats [top]

Major Threat(s):

The severity of threats varies with the forms and locations. Certain subpopulations and forms are highly threatened by illegal collection and a quarry in the case of Mammillaria crinita tezontle. Development for agriculture and urbanization impacts some subpopulations, but does not represent a major threat to the overall population. Temperature extremes such as the 100-year freeze on the Altiplano in December 1997 present a serious but unpredictable threat.

Conservation Actions [top]

Conservation Actions:

This species is legally protected in Mexico, where it is listed as “subject to special protection” on the national list of species at risk of extinction, NOM-059-SEMARNAT-2001 (Pr; SEMARNAT 2010). Certain forms and subpopulations require site level conservation, such as M. c. tezontle.
