Mammillaria elephantidens Lem.
|Taxonomic Source(s):||Hunt, D., Taylor, N. and Charles, G. (compilers and editors). 2006. The New Cactus Lexicon. dh Books, Milborne Port, UK.|
|Taxonomic Notes:||This species comprises three subspecies - the typical form, subsp. bumamma (Ehrenb.) Dicht & A.Lüthy, and subsp. greenwoodii (Bravo) Dicht & A.Lüthy. The typical subspecies and subsp. bumamma are not threatened and hence are not listed separately; subsp. greenwoodii was assessed as Endangered in 2002, but it has not been reassessed here, hence the former listing has been dropped.
|Red List Category & Criteria:||Least Concern ver 3.1|

Coryphantha elephantidens is listed as Least Concern because it is widespread and relatively common. One subspecies, C. elephantidens greenwoodii, in the state of Veracruz, is threatened by development in its restricted range.
|Previously published Red List assessments:|
|Range Description:||This species is endemic to Mexico where it is known to occur in the states of Aguascalientes, Guerrero, Guanajuato, Hidalgo, Jalisco, México, Michoacán, Morelos, Oaxaca, Puebla, Querétaro, Veracruz and Zacatecas (Dicht and Lüthy 2003, Hernández et al. 2004, Hunt et al. 2006). The subspecies C. elephantidens greenwoodii has a restricted range near Piedras Blancas, Veracruz. Subspecies bumamma is recorded from the States of Oaxaca and Michoacán.|

|Population:||The populations are usually disjunct within the area of one state or between one or two contiguous states (Hernández and Godínez 1994). It is relatively common where found. In Huautla Biosphere Reserve, Morelos, a total of 68 individuals per 0.75 ha were recorded in perturbed areas, while in conserved areas a total of 4 individuals per 0.75 ha were found (Arias-Medellín and Martínez-Garza 2007).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species is found in grasslands and xerophyllous scrub (H. Hernández pers. comm. 2009).|
|Use and Trade:||This species is locally used as an ornamental.|
This species is threatened by deforestation from small-holder agriculture and cattle ranching.
|Conservation Actions:||Coryphantha elephantidens occurs in the Huautla Biosphere Reserve. The species is legally protected in Mexico by the national list of species at risk of extinction, NOM-059-SEMARNAT-20010, where it is listed under category “threatened” (A; SEMARNAT 2010). The subspecies C. elephantidens greenwoodii has a restricted and threatened range it is also listed in NOM-059-SEMATNAT-2010 under category "subject to special protection" (Pr: SEMARNAT 2010). This species needs further research on taxonomy and population dynamics.|
