How To Support Our Threatened Desert Tortoise

Watching for Wildlife: What is a Desert Tortoise?

Small and shy, it would likely take patience and perfect timing to see a desert tortoise in the wild. They spend up to 95 percent of their life underground, digging burrows in a wide variety of terrain — especially near alluvial fans, washes and canyons where ancient rivers left behind soil ideal for native plants and wildlife den construction.

A mature tortoise can reach up to 15 inches in length and 6 inches in height with a high, domed shell featuring distinctive growth lines. They hibernate up to nine months of the year, becoming most active from March to June, and again from September to October. Desert tortoises live 50 or more years in the wild, and up to 80 in captivity with care from wildlife experts.

Wildlife in Danger: The Desert Tortoise Habitat is Disappearing

Despite having lived in our region for millions of years, the desert tortoise is one of the most elusive wildlife species. As recently as the mid-1900’s they were a common site, but permanent habitat loss due to urbanization and large-scale renewable energy projects have caused them to disappear entirely from some areas. Features like roads, highways and off-highway vehicle activity also cause severe damage to their natural habitats, cutting their territory into fragments of what it used to be and threatening the native plants they feed on.

In 1990, the U.S. Fish and Wildlife Service officially listed the desert tortoise as “threatened.”

Supporting Wildlife: Grow Native Plants in Your Garden

Because desert tortoise live in an area where most of the rainfall occurs during the monsoons, it will get most of its food for the year during this period, as well as the majority of its water. It eats the leaves, stems and flowers of many species of desert plants, and can ingest species of native plants that other wildlife do not with the aid of bacteria that live in its digestive system.

Following are native plants recommended by the Tortoise Group, a nonprofit dedicated to the preservation of the desert tortoise. They will grow well in our climate and provide much needed food and water for the reptiles.
