It is characterized by scrub and desert landscapes featuring many cirio trees. The wildlife area is largely untouched and well-conserved, featuring a large number of endemic species including abundant concentrations of cacti, reptiles and large mammals. The Valley of the Cirios is on the Mexican Tentative List of sites that may become a World Heritage Site.
