This diversity can be explained in part by the Monument's location. The vegetation is dominated by jojoba, followed by palo verde and brittlebush. Other plants include various species of cholla, saguaro, sotol, yucca, agave, ocotillo, and native and nonnative grasses. A small riparian area contains sycamore, walnut, hackberry, and dewberry.
