Species Description

Named for their large mule-like ears, mule deer are the only species of deer that live in the Truckee River region.  They have brown bodies, and white tails tipped with black.  Along the Truckee River between Truckee and Verdi, you may see members of the Verdi sub-unit of the Loyalton-Truckee mule deer herd.  These deer migrate each year from their winter range in Nevada up the Truckee River/I-80 corridor to Martis Valley and on to fawning grounds near Union Valley (DC&E, 2006).  Their movements are being studied by the California Department of Fish and Wildlife and the Nevada Department of Wildlife, and some of the deer have been outfitted with satellite radio collars (CA Department of Fish & Wildlife, 2015).  As of 2014, there were approximately 1,700 deer in the Truckee-Loyalton herd (Delong, 2014).

Mule deer feed at night on a variety of plants, grasses, farm crops, and even mushrooms.   Populations of mule deer across the state of Nevada reached an all-time high during the 1980’s, and have since been in decline (Wasley, 2004).  They use riparian areas for reliable sources of water, food, and cover for young fawns, which spend the first few months of their lives hiding in dense vegetation (Leckenby, et al., 1982).
