Taxonomy [top]

Kingdom Phylum Class Order Family
PLANTAE TRACHEOPHYTA MAGNOLIOPSIDA CARYOPHYLLALES CACTACEAE

Scientific Name: Mammillaria luethyi
Species Authority: G.S.Hinton
Common Name/s:
Spanish Biznaguita
Taxonomic Notes: Accepted as a valid species by Anderson (2001), Hunt (1999) and Pilbeam (1999).

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2013
Date Assessed: 2009-10-15
Assessor/s: Fitz Maurice, W.A., Fitz Maurice, B & Hernández, H.M.
Reviewer/s: Chanson, J.S. & Goettsch, B.K.
Facilitator/s: Wyatt, S.
Justification:
This species is listed as Vulnerable because it is known from only two locations and has an area of occupancy less than 20 km2. If the two locations were publicly known the threat from amateur collectors would be very high leading to the species becoming Critically Endangered or Extinct in a very short period of time.
History:
2002 Endangered

Geographic Range [top]

Range Description: This species is found in the state of Coahuila, Mexico, at elevations of around 800 m asl.

Population [top]

Population: At the time of publication of this species in 1996, it was thought to occur over a range of less than 200 m2, with an estimated population of less than 200 individuals. However, in 2006, the authors discovered a new population some kilometres distant from the original site and estimate the numbers of individuals found there to be many thousands (Lüthy 2007).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species grows on sloping calcareous rocky terrain in semi desert.
Systems: Terrestrial

Threats [top]

Major Threat(s): This species is the most sought after cactus by collectors because of its rarity and unusual spines. If the localities were to be discovered by collectors, the populations would be subject to major declines. The precise locality is known only to a small number of experts. Despite the readily available populations in commercial cultivation, an intensive search for the localities continues by amateur and commercial collectors.

Conservation Actions [top]

Conservation Actions: The plants are widely available throughout the world as a result of propagation from illegally exported specimens propagated from the original collection with approval of low level Mexican government officials. At this time, conservation measures would be counterproductive if they involved the type locality. It is listed on CITES Appendix II, but enforcement of the laws in the countries of destination is needed.
