Mule deer in the Izzenhood herd are part of a larger population known in Nevada as the “Area 6” mule deer population. They primarily reside on winter ranges in the Izzenhood Basin and upper Rock Creek drainages in western Elko County and northern Lander County. From their winter range, mule deer in this sub population migrate approximately 70 miles to summer ranges in the northern Independence Mountains and Bull Run Basin area. Some of the most important stopover areas are located near upper Rock Creek, Toe Jam Mountain, and Chicken Creek Summit. Challenges to this deer herd include past wildfires on winter range, conversion of native shrub habitats to exotic annual grasses, and lower primary production in some...

Mule deer in the South Tuscarora herd are part of the larger “Area 6” deer population that reside in the southern and eastern portion of this big game Management Area (MA 6). The winter range for this sub population is located along the western slopes of the Tuscarora Mountains and the Dunphy Hills. The spring migration route for this deer herd traverses north along the toe slopes of the Tuscarora Mountains on the east side and narrows to approximately 600 meters at one pinch point near the Carlin -Pete Mine area. The migration route generally spans about 30 miles to the northeast to higher elevations in the northern Tuscarora Mountains. Important stopover areas include Richmond Mountain, Jack and Little Jack Creeks,...
Mule deer within the Red Desert population, part of the larger Sublette herd, make the longest ungulate migration ever recorded in the lower 48 states (fig. 33). Here, mule deer travel an average one-way distance of 150 mi (241 km) from the Red Desert in the south to the Gros Ventre Range and Teton Range in the north. This migration originates in the desert sagebrush basins of the Red Desert area of southwest Wyoming where deer winter. In spring, an estimated 500 deer travel 50 mi (84 km) north across the desert to the west side of the Wind River Range. From there they merge with 4,000 to 5,000 other deer that winter in the foothills of the Wind River Range and then travel a narrow corridor along the base of the...
The Platte Valley Herd Corridor was designated by the Wyoming Game and Fish Department in 2018 (fig. 30). The Platte Valley herd contains approximately 11,000 mule deer. The corridor is based on two wintering populations, including a south segment from Saratoga, Wyoming, to the Colorado State line, and a north segment from Saratoga to the Dana Ridge area north of I-80. Winter ranges in the Platte Valley are more dispersed than winter ranges in other parts of the state, so deer migrate in many different directions. Many deer in the southern segment follow the Platte River south to summer ranges in Colorado. Most deer migrations in the north radiate south and east from winter ranges along I-80. The WGFD collared 45...

The Area 10 mule deer population is one of the largest deer herds in the state, accounting for roughly 20 percent of the statewide mule deer population. The Area 10 herd is comprised of several sub populations that occupy the majority of the Ruby Mountains, are highly migratory,and exhibit long distance migrations from summer to winter ranges. Several key stopovers occur within the migration corridor for the Area 10 deer migration. The largest stopovers are located along the Harrison Pass Road on both sides of Toyn Creek,the west side of Pearl Peak and Sherman Mountain, Little and Big Bald Mountains near the Bald Mountain Mine complex, and Bourne to Orchard Canyons west of Warm Spring Ranch. The winter range encompasses...
