Mojave desert tortoise

A long-lived desert reptile whose slow life history and reliance on shelter make disturbance especially costly.

A Mojave desert tortoise carries a high, rounded shell above stout legs built for life on land. The front limbs are adapted for digging, the hind limbs look column-like, and the tail is short. It is a plant eater, taking grasses, herbs, flowers and cactus material. Its presence in southwestern Utah reflects the state's connection to the Mojave Desert, not a range extending across every Utah red-rock landscape.

Burrows are essential shelter from conditions at the surface, and tortoises spend much of their time out of sight. Above-ground activity is usually more likely during favorable spring or autumn conditions than during temperature extremes; rainfall and local weather matter. Its long life is another reason to consider the lasting effects of a disturbance. Removing an adult can therefore cost a wild population far more than one season of reproduction.

The Mojave population remains federally threatened, as confirmed by current DWR material checked in October 2026. Habitat loss and fragmentation, road mortality, disease, wildfire associated with invasive vegetation, and predation on eggs and young all figure in its conservation challenges. DWR warns that taking a wild tortoise home is illegal and that captive animals must not be released into the wild. An encounter should end with the animal still in its own habitat, free to reach its shelter.
