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...
Elk (Cervus elpahus canadensis) within the southern section of the Bighorn Mountains display altitudinal migration. In the spring, most individuals migrate from the western foothills up into the mountains, and in the fall, they head back down to lower elevations (fig. 68). In the southern section where the range curves west, the herd migrates up the northern foothills in the spring and back down in the fall. Additionally, a few individuals will summer on the eastern foothills along the Crazy Woman drainage. These individuals migrate west up the slopes in the spring and back down in the fall. The herd, which numbers around 4,000, primarily winters along the western foothills of the southern Bighorn Mountains just...

South of Interstate 40 mule deer reside in Game Management Units (GMU) 8 and 6B in Arizona. The herd summers in high-elevation open meadows and ponderosa pine habitat southwest of Flagstaff, Arizona. In late October, the herd migrates west to lower elevation pinyon-juniper and shrub habitats near the junction of Interstate 40 and U.S. Highway 89. With funding support by the U.S. Department of the Interior (USDI) through Secretarial Order 3362, research on this herd’s migration began in February 2020. Additional GPS collars were deployed in January 2022 with support from the U.S. Forest Service, Mule Deer Foundation, and other partners. Primary threats to the herd’s migration involve high volume roads including Interstate...

The Siskiyou mule deer herd migrates from winter ranges primarily north and east of Mount Shasta (i.e., Day Bench, Lake Shastina, Montague, Mount Dome, Mount Hebron, Sheep-Mahogany Mountain, Tionesta, and Wild Horse Mountain) to sprawling summer ranges scattered between the Mount Shasta Wilderness in the west and the Burnt Lava Flow Geological Area in the east. A small percentage of the herd are residents, residing largely within winter ranges across the central and northeast areas of the herd’s annual distribution. The total population size of the Siskiyou herd is unknown, but adult deer densities averaged 6.01 deer per km2 on summer ranges in 2017 and 5.16 deer per km2 on winter ranges in 2019 (Wittmer and others,...

Mule deer within the Jackson segment of the Sublette herd winter mainly in the valley and south-facing slopes of the buttes. These geologic features are characteristic of the Jackson Hole area near Jackson, Wyoming. Winter ranges in the Jackson valley are a mixture of national forest public land as well as private urban and exurban land. The lower elevation, south-facing hillslopes are typified by stands of Juniperus scopulorum (Rocky Mountain juniper) or mixed mountain shrub communities of Artemisia tridentata (mountain big sagebrush), Artemisia tripartite (three-tip sagebrush), Purshia tridentata (antelope bitterbrush), Amelanchier alnifolia (Saskatoon serviceberry), Symphoricarpos albus (common snowberry), chokecherry,...
The Methow mule deer (Odocoileus hemionus) sub-herd is part of the larger West Okanogan herd, the largest migratory mule deer herd in Washington State. Individuals travel as far as 65 miles twice annually between lowland winter range and higher elevation summer range (fig. 27). Mule deer wintering on the shrubsteppe dominated foothills in the lower half of the Methow valley undertake a roughly 3-week trek in mid-spring to the productive subalpine and alpine meadows of the Pasayten and Chelan Sawtooth Wilderness, and surrounding high country, with some animals traveling north into British Columbia. On summer range they mingle with deer moving up from the west side of the Okanogan valley forming an estimated summering...

The Blue Canyon mule deer herd winters in the western foothills of the Sierra Nevada south of Interstate 80. The winter range includes dense conifer and oak woodland that is shared with a resident portion of the herd on a mix of public and private lands. In the spring, the Blue Canyon herd migrates from their winter range eastward along two main paths both north and south of the Forest Hill Divide to higher elevation terrain near Soda Springs and the crest of the Sierra Nevada in the Granite Chief Wilderness. The summer range includes primarily mixed conifer opening up to high alpine granite near the crest of the Sierra Nevada. The population size is not well known due to limited surveys, but is considered stable...

The Chelan mule deer herd occupies a mix of private and public lands from the Columbia River to the crest of the Cascade Range in central Washington. U.S. Highway 2, northwest of Wenatchee, Washington, serves as the southern boundary for this herd and Lake Chelan bounds the northern edge. The high-use winter range includes the southeastern shore of Lake Chelan, the breaks of the Columbia River, the lower Entiat River drainage, and the foothills east of Cashmere, Washington. In the spring, migratory individuals travel northwest into the Entiat and Chelan Mountains to their summer ranges, such as regional Wilderness areas. A small sample of Chelan mule deer was captured near the Swakane Wildlife Area in January 2020...

Along the eastern slope of the Cascade Mountains in Chelan and Kittitas counties, the Wenatchee Mountains mule deer herd inhabits a matrix of private and public lands. Historically, the Wenatchee Mountains mule deer were separated into two sub-herds, Chelan and Kittitas; however, recent movement data from GPS-collared individuals associated with Secretarial Order 3362 (Department of the Interior, 2018) revealed that the mule deer south of U.S. Highway 2 and north of Interstate 90 represent one population. Their high-use winter range extends along the foothills west and south of Wenatchee, Washington and throughout the foothills of the Kittitas Valley outside Ellensburg, Washington. The low-use winter range occurs...

The Medicine Bow pronghorn population is one of the largest herds in the United States with an estimated population of 38,400 animals. The herd summers in the sagebrush steppe and grasslands of Shirley Basin, north of Medicine Bow, Wyoming. Most pronghorn migrate either west to the southern edge of the Seminoe Reservoir or north to Bates Hole, an area south of Casper, Wyoming. During harsh winters, some pronghorn migrate 65–75 miles (105–121 km) as far west as Rawlins, Wyoming. The Shirley Basin is a mostly intact landscape that is dominated by private lands, with only limited public lands along some foothill habitats. During the early 2000s, several large wind energy facilities were developed; some are in high-use...
Moose in the Jackson herd make an elevational migration in the southern portion of the Greater Yellowstone Ecosystem. This small herd of approximately 500 animals winters primarily in the Buffalo Valley just east of Jackson Lake. During migration, animals travel an average one-way distance of 33 miles, with some animals migrating as far as 67 miles. In the spring, most moose migrate north into the Teton Wilderness or the southern extent of Yellowstone National Park. Summer ranges consist of a mix of conifers and riparian habitats along the upper watersheds that flow into the Snake River. Nearly all moose in this herd are migratory, with the herd sharing a common winter range then branching out in the spring to summer...
Mule deer in the Atlantic Rim South population are part of the Baggs herd unit that is managed for approximately 19,000 animals. These mule deer winter in the sagebrush canyons and basins north and west of Baggs, Wyoming and migrate north and east 20–50 mi (32–80 km) to various summer ranges (fig. 23). Many of these deer must navigate coal-bed methane developments situated along the migration route between their seasonal ranges. In addition to navigating gas developments, many of these deer cross Highway 789 during winter and migration. The Wyoming Department of Transportation (WYDOT) recently installed two underpasses and several mi of game-proof fencing to facilitate highway crossings across Highway 789 and help...
This study was tailored toward the Wyoming section of Interstate 80 (I-80), and so migrations and habitat use are more representative of pronghorn (Antilocapra americana) along I-80 rather than the entire populations. The Uinta-Cedar populations had the highest prevalence of seasonal migrations. This area primarily occupies checkerboard ownership between Bureau of Land Management and private ownership. Oil and gas drilling as well as sheep ranching are relatively common. Seasonal ranges are characterized by arid to semiarid habitats with sagebrush (Artemisia spp.) as the predominant vegetation type. Seasonal ranges can also include interspersed grasslands, and low-lying areas can also include black greasewood (Sarcobatus...
Elk (Cervus elpahus canadensis) within the southernmost section of the Absaroka Range, just north of the Wind River Range, display altitudinal migration (fig. 71). In the spring, they migrate from the southern foothills near Dubois up into the mountains, and in the fall, they head back down to lower elevations. The herd, which numbers around 6,000, primarily winters between the Absaroka Range to the north and the Wind River Range to the south. Winter ranges consist mostly of shrubs, largely supported by private land with smaller areas of BLM and Wyoming Game and Fish land. During migration animals travel an average one way distance of 32 mi (51 km) ranging from as little as 8 mi (13 km) to as far as 69 mi (111 km)....

The Big Lake pronghorn herd resides in the White Mountains of eastern Arizona within Game Management Unit 1. Mid-March, the Big Lake pronghorn migrate, crossing the Little Colorado River approximately four miles north of River Reservoir, to their high-elevation summer range. The summer range consists primarily of high-elevation grasslands and large alpine meadows near Big Lake. Some individuals continue several miles farther south to summer near Middle Mountain. Fall migration occurs in early to mid-October, when the herd moves north to low-elevation grassland habitats west of Eagar, Arizona. The primary threat to this migration corridor is State Route 260, which experiences high traffic volume and requires crossing...
