Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2010-05-10
Assessor(s): Burquez Montijo, A. & Felger, R.S.
Reviewer(s): Goettsch, B.K.
Facilitator/Compiler(s): Gaston, K.
Justification:
This species is considered to be Least Concern in light of its presumed large population size and distribution and lack of major threats, however further research is necessary to ensure that this species is not in fact declining at a rate to qualify for a threat listing. The species is poorly known taxonomically and ecologically, there are no recent collections and therefore there is no information on the current population trends to assess it. The area where it occurs has been inaccessible for a long time.

Geographic Range [top]

Range Description: This species occurs in the Mexican state of Sonora (Hunt et al. 2006), where it grows at elevations of 250 to 1,350 m. Taylor (1985) reports the species to also occur in adjacent south-eastern Arizona, in Cochise County.

Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: The species grows in thornscrub in foothill (Paredes et al. 2000). Taylor (1985) found it in Northeast Sonora and border region of adjacent Southeast Arizona in the sonoran Desert and desert grassland.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species is not utilized.

Threats [top]

Major Threat(s): Land use change is a threat affecting this species, however it is not a major. In the species range in the United States the main driver of land use change affecting subpopulations is urbanization. In the Mexican part of the species range is agro-industrial ranching and activities related to this, such as deforestation. However, the vast part of the subpopulations grow on poor, rocky soils not suitable for agriculture or ranching.

Conservation Actions [top]

Conservation Actions: The 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).
