Moreover, the various associations of desert scrub (crassicaule, thorny and microphyll scrub) identified in the study area had a similar number of genera and species than those of Quercus forests, despite that these associations cover much more area of the Valle del Mezquital region (Gonzalez-Quintero, 1968).
