Habitat destruction/modification
The desert tortoise is a state and federally listed threatened species and is protected by law under the Endangered Species Act of 1973
The Endangered Species Act requires us to have a USFWS biological opinion for activities conducted on base
Abide by all base rules and policies
Predation by ravens, wild dogs, and humans. A raven’s nest was found near Kramer Junction with over 260 baby tortoise shells under it.
The DT is susceptible to Upper Respiratory Tract Disease that box turtles get. It is deadly to wild tortoises.
Vandalism and poaching is easy because they are slow and appear tough/indestructible
It is illegal to take a wild tortoise in as a pet. They are also likely to get URTD
The desert is fragile habitat. Habitat depletion happens when any undisturbed area becomes disturbed. This means driving off road, picking plants, and even walking off trails. Please stay in previously disturbed areas to avoid damaging DT habitat, food, or burrows.

3. Typical Burrow Hatchling Tortoise
Tortoises, carcasses, eggs, and their burrows are protected.
Do not collect shells or bones.
Don’t walk on top of a burrow. Burrows are dug at a shallow angle and could collapse.
Don’t walk directly in front of the burrow. Females generally lay their eggs in the front portion of their burrow and the eggs may be damaged.
A good rule of thumb is to remain 15 feet away from a tortoise or burrow.
Note the relative size of the hatchling to the quarter. They are very small and soft-shelled. Please watch where you walk, especially during hatching season. All tortoises look like rocks.
