Conservation Status: Endangered.


Stephens' Kangaroo Rat is endangered, chiefly due to habitat loss. It lives only in isolated populations in three counties of southern California. The Kangaroo Rats maintain a network of aboveground trails that follow the lines of their tunnels and connect burrow openings. Their home ranges average 570-970 square meters, but may be as large as 1,600 square meters. Living in association with this Kangaroo Rat in sparsely vegetated annual grassland and sage-scrub communities are Deermice, Agile and Dulzura's Kangaroo Rats, and Desert Woodrats. Domestic dogs and cats prey on this species, as do owls, coyotes, foxes, and snakes.
