Conservation Status: Least Concern.

Idaho Pocket Gophers are active all year long. When they excavate burrows in the winter, they leave the dirt piled in snow tunnels. After the snow melts, piles of soil remain as evidence of their wintertime activity. They are small for the genus, probably solitary, like other pocket gophers, and also probably have a typical life span for the genus of less than two years. Predators include skunks, coyotes, weasels, hawks, and owls.

Also known as:
Pygmy Pocket Gopher

Sexual Dimorphism:
Females are slightly larger than males.

Range: 167-203 mm

Range: 46-88 g
