Rank ReasonsQuercus toumeyi is a shrub or small tree that occurs in the southern mountain ranges of New Mexico and Arizona, southward into Chihuahua and Sonora in Mexico. While the distribution, threats and trends are not well known for Mexico, the species has relatively low threats in the U.S.A. Most occurrences are on protected lands, have no major threats, and their populations are described as locally common or a dominant groundcover.
Range Extent CommentsQuercus toumeyi occurs in southern Arizona and New Mexico, south through central western Chihuahua and Sonora. In Arizona and New Mexico, it occurs in ten mountain ranges (Wiens and Thibault 2019). The species also occurred in Texas but it is believed to be lost to introgression (Beckman and Jerome 2017).
Occurrences CommentsThe number of occurrences are not defined throughout the species range. In Mexico even less so, especially in the southern portion of its range, where taxonomic confusion may exist where Quercus barrancana overlaps in range (Beckman and Jerome 2020, Spellenberg 2014).
Threat Impact CommentsIt is on protected lands with no significant threat in nine of the mountain ranges of Arizona and New Mexico where this species occurs, (Wiens and Thibault 2019). Threats in Mexico are unknown. Introgression may be a threat in some areas.
