Desert tortoises: One of Edwards AFB’s natural residents

A desert tortoise sign installed by the 412th Civil Engineer Group on the side of North Rosamond Boulevard towards the North Gate of Edwards Air Force Base.

The desert tortoise is one of the many animals found at Edwards Air Force Base in Southern California.

Listed as threatened under the federal Endangered Species Act of 1973, desert tortoises are protected from unwarranted harassment or injury.

The 412th Civil Engineer Group’s Environmental Management Division wants to remind base residents to be on the lookout for desert tortoises, especially near or crossing roadways. The 412th CEG Environmental Management office has installed tortoise awareness signs on roads where desert tortoises are regularly observed.

“The new signs near North Gate and Dats Road are a result of consistent desert tortoise activity and a desert tortoise death on North Rosamond Blvd. due to a vehicle collision,” said Larry Zimmerman, 412th CEG, Environmental Management Natural Resources manager.

Tortoise signs have been placed in various locations throughout the base over the years due to reoccurring desert tortoise sightings along roads, near buildings and under parked cars where desert tortoises seek shelter from the elements. People working or living on Edwards are encouraged to check under and around vehicles prior to moving their vehicles, especially if parked near open desert, according to Zimmerman.

If a desert tortoise is seen and not in immediate danger, people are advised not to touch the animal and monitor the animal until it reaches safety. Environmental Management should be contacted immediately if a tortoise is seen, whether in danger or not. Only authorized and trained people are allowed to touch a desert tortoise in non-emergency situations. Unauthorized handling could result in a $50,000 fine and jail time.

If a motorist encounters a desert tortoise in immediate danger on or near the road, they can pick up the desert tortoise and move it off the road, according to Environmental Management. Slowly approach the desert tortoise from its front, pick it up by its sides, keep it level, and place the tortoise pointed in the same direction it was heading at least 100 feet off the road in a shady place. After moving a desert tortoise, call the Environmental Management office so a trained biologist can make sure the animal is okay.

Zimmerman said desert tortoises are particularly active March through May and again from September through October. However, desert tortoises can be active at any time throughout the year, especially during and after rainfall. 

Anyone who encounters a desert tortoise in distress should call Environmental Management at 661-277-1401.
