État de la populationTexte officiel évaluation IUCNExpert
This species can form pure stands and can be dominant or co-dominant in certain habitats (Pavek 1993). It is also widespread, hence it is assumed that the population is large. The population is reported to be stable by Nature Serve (2018) in the United States. Information is not available for population in Mexico.

Description complète des menacesTexte détaillé évaluation IUCNExpert
In the future the species may become affected by climate change. A study by Potter et al. (2017) identified the species to have 'high vulnerability and potential adaptation' in response to climate change. Further information is needed to fully understand this risk to the species. Otherwise, in the US, the species is not considered threatened. For Mexico, threats to the species are unknown.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
This species is reported from 28 ex situ collections (BGCI 2018). The species has most recently been considered Threatened in Mexico (SEMARNAT 2010) but in 2005, a separate assessment for Mexico found the species not threatened (BGCI ThreatSearch 2018). For the US it is assessed as G4 - Apparently Secure (Nature Serve 2018).
