Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2017
Date Assessed: 2009-11-17
Assessor(s): Fitz Maurice, B, Fitz Maurice, W.A., Hernández, H.M., Sotomayor, M. & Smith, M.
Reviewer(s): Schipper, J.
Justification:
This species has an extremely small range (extent of occurrence and area of occupancy is about 25 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 population declines at a rate sufficient to qualify for a threat category. Hence the species is listed as Near Threatened because it almost qualifies for a Critically Endangered listing under criterion B1ab(v).

Population [top]

Population:The estimates in population size vary considerably, with 100,000 being an agreed lower limit and perhaps over one million the upper limit. Despite illegal collection, the population is stable and not decreasing.
Current Population Trend:Stable
Additional data:
Number of mature individuals:1000000Continuing decline of mature individuals:No
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species grows on gypsum cliffs and hillsides, it is a soil specialist - a gypsophile (Anderson 2001, Hernández and Gómez-Hinostrosa 2011).
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:No

Use and Trade [top]

Use and Trade: There is illegal trade and the species has been found in seizures (Bárcenas 2003).

Threats [top]

Major Threat(s): 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 themselves.

Conservation Actions [top]

Conservation Actions:

This 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 category “subject to special protection” (Pr; SEMARNAT 2010).

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

It is recommended to consider uplisting to CITES Appendix I, increase commercial propagation, protect wild populations and monitor commercial availability in foreign countries (Bárcenas 2003).
