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

Habitat and Ecology [top]

Habitat and Ecology:This species grows on limestone plains (and areas of gentle slopes) in regions of xerophyllous scrub, rarely occurring in gypseous soils (Powell and Weedin 2004). It occurs on hills or ridges in desert at altitudes from 500 to 1,170 m asl (Kartesz 1994, Hernández and Gómez-Hinostrosa 2011).

Use and Trade [top]

Use and Trade: This species is collected from wild populations and used as an ornamental throughout its range.

Threats [top]

Major Threat(s): There is illegal collection of the species from the wild but at a diminishing rate.

Conservation Actions [top]

Conservation Actions: This species exists in many protected areas across its range; however, there is no enforcement in the majority of these areas. Thus, the actual level of protection is unknown (Kartesz 1994).This cactus is listed on CITES Appendix I.
