California's Desert Tortoise


After existing for millions of years in the California desert, the desert tortoise is experiencing continued, rapid population declines throughout its range. Many of the threats to tortoise are human related, including military base expansion, road construction, livestock grazing, and unmanaged off-road vehicle recreation. However, there is still time to act. Check out our new story map and support Defenders as we petition to change the status of the desert tortoise from threatened to endangered and ensure the tortoise gets the protection it needs.
