A primary herbivore in the Basin and Range is Mule deer.

Mule deer are common herbivores in the Basin and Range Province, thriving in the region's varied landscapes, from deserts to mountainous areas. They primarily feed on shrubs, grasses, and forbs, making them well-adapted to the limited vegetation typical of arid environments. Mule deer are a crucial part of the ecosystem, as their grazing patterns help shape the plant communities, and they serve as a food source for predators such as coyotes and mountain lions. Their adaptability to the Basin and Range's dry conditions and diverse terrain makes them one of the region’s prominent herbivores.
