Conservation Status: Least Concern.

Pygmy Rabbits dig extensive burrow systems, which are also used by other animals. Loss of habitat is a direct threat to this species, which depends on big sagebrush, particularly mature stands of it. Both birds and mammals prey on pygmy Rabbits, which are an important food for many of the other animals in its range. The rabbit's habitat has become increasingly fragmented by development, agriculture, rangeland "improvements"—for example, projects that replace big sagebrush with bunchgrasses—and by fire. There is reason to be concerned about the future of this smallest North American member of the rabbit family.
