This could have life-threatening consequences for the animal if it is not able to replenish its water supply.
It has been postulated that elemental toxicity may compromise the immune system of desert tortoises or otherwise detrimentally affect physiological function, rendering them more susceptible to disease, but further investigation is needed.Desert tortoises, particularly hatchlings and juveniles, are preyed upon by several native species of mammals, reptiles, and birds. However, it is not known whether this is a cause or effect. As more people moved into the western deserts, the resultant loss of habitat made a serious dent in the number of tortoises.

The female lays a clutch of 1- 14 hard-shelled eggs in a nest in May, June and July, and leave the nest to be incubated by the warm soil.
It is used to being cared for, and may have lost its instincts to forage and protect itself from predators. The following is an overview of the threats to the Mojave desert tortoise and its habitat by the five listing factors used to determine the desert tortoises' protection under the Endangered Species Act.
Its status is \"threatened,\" just one notch below \"endangered.\" Several factors conspired to diminish the population of the desert tortoise. This highlights the importance of combined and synergistic effects of threats. Illegal collection for the pet trade, destruction of their habitats by urban area expansion and off-road vehicles, and increased predation by ravens are some of the factors contributing to the desert tortoise’s decline.

In Danger of Extinction: There are a few causes for the Desert Tortoise being listed threatened on August 20, 1998.
Half of their species are threatened with extinction,” says Dr. Anders Rhodin, Chair of the TFTSG and one of the report’s co-editors. The number of ravens has exploded in recent years, due in large part to their ability to thrive in developed areas.
They inhabit semi-arid grasslands, gravelly desert washes and sandy canyon bottoms below 3,500 ft.
Perhaps this long stint on Earth has given them plenty of time to consider wise living strategies, such as careful, slow-paced locomotion; a healthy diet full of greens; resting during winter and summer, the desert's most challenging seasons; and water conservation. It has two subpopulations — the Mojave and the Sonoran — that are separated by the Colorado River.Road construction, energy development, grazing and off-road vehicle use have degraded and destroyed habitat for the desert tortoise and continues to threaten the species. Like a young child who may wet his pants when afraid, a tortoise will "void" its bladder if frightened.
