The Mexican subpopulations are outside formal reserves. The remaining stands of this subspecies should come under such protection, where logging, grazing and burning can be policed and controlled. Ex-situ conservation involving the collection of seed from all stands and the establishment of breeding populations in suitable areas should be a priority.
According to the Secretaría de Medio Ambiente y Recursos Naturales (Mexico) (2010) this species is in danger of extinction.
