» Life History

Habitat Requirements

Lives in moist, grass/sedge habitats along permanent or semi-permanent waters (springs or seeps). Also found in pinyon-juniper and pine oak associations with a variety of shrubs and grasses.

Food Habits

Hypothesis that the diet includes green plant material, such as grasses, sedges, and forbes. Further studies are needed.

Movement / Home Range

Species confirmed only in the Hualapai Mountain Range and possibly in the Prospect Valley and Music Mountains. Has been found between 1645 and 2560 meters of elevation. Ongoing research suggests that populations may occur in the Hualapai Nation, Aubrey Cliffs, Chino Wash, Santa Maria Mountains, Bradshaw Mountains, Round Mountains, and the Sierra Prieta Mountains.

Reproductive Strategy

Only two mammary glands are present on females, which limits the number of young that can be nourished. Further studies are needed to determine reproductive cycles, and attributes.
