Prickly pear cactus (Opuntia engelmannii) that is drought stressed as well as having been gnawed at by rodents that need the moisture. In the background, a young Saguaro cactus (Carnegiea gigantea) with a dying Cane cholla (Cylindropuntia imbricata) at its base. The extended drought is even killing plants that are drought tolerant.
