Justification
Aztekium hintonii has an extremely small range, both the extent of ocurrence and area of occupancy are about 50 km². The area is essentially a single location, and there is ongoing illegal collection of the species. However, the population is extremely large and the collecting does not seem to be causing any declines. Hence, the species is listed as Near Threatened because it almost qualifies for a Critically Endangered listing under criterion B1ab(v).

Threats

Major Threats
Illegal collection is the main threat. However, now it is protected by the local population (Pilbeam and Weightman 2006). The local population is safeguarding the species in order to sell it itself.

Conservation Actions

This cactus 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 local population guard the plants and prevent illegal collection (Pilbeam and Weightman 2006), but the area has no protected area status.
