Cacti are moderately abundant in these two vegetation types. The ceniza shrub type is dominated by deciduous and evergreen shrubs with scattered openings with grass species. Cacti are common as well as other spring shrubs. Cattle are the primary grazers in this region, but sheep and goats are also important with combinations of those three species likely providing the best grazing use. Conversion of the brushy areas to a grassland is frequent, but revision of the shrubby species is rapid.
Deer management is a common practice with hunting leases sold over much of the area.
