Losing habitat

Like many species of wildlife, the greatest threat to the desert tortoise is loss of habitat due to human activity and development. In some areas of the American deserts, the desert tortoise population has decreased by 90 percent. Vehicle traffic both on highways and on the open desert are especially damaging to the tortoise population. In the Western Mojave Desert, a study showed that the desert tortoise population is, on average, 200 adults per square mile. Today, that number is thought to be just five to 60 adults per square mile.

Adapting to life

The deserts of North America are inhabited by many species of plants and animals that have adapted well to the extreme temperatures and dry conditions found across this vast landscape. The desert tortoise is just one such splendid example of life's ability to acclimate to any environment. Conservation projects are ongoing in the United States and Mexico to assure that the desert tortoise is a part of this amazing desert ecosystem forever.
