The Desert Tortoise Research Natural Area (DTRNA) is 39.5 square miles of prime, natural habitat set aside for the desert tortoise, the official California State Reptile. No OHV use is allowed in the preserve. The preserve boasts rich flora and fauna representative of the intricate Mojave Desert ecosystem. In 1980, the BLM recognized the significance of the DTRNA by designating it an “Area of Critical Environmental Concern” and a “Research Natural Area.” The Interpretive Center, with parking lot, information kiosk, restroom, and access to self-guided trails, is located about 4 miles northeast of California City just off the unpaved Randsburg Mojave Road.
