The South of Interstate 40 (I-40) pronghorn (Antilocapra americana) herd make one of Arizona’s most remarkable migrations. This herd resides primarily in GMU 8, which had a population estimate of 450 individuals in 2019. Unlike traditional summer-winter range dynamics, this pronghorn herd relies on a complex of several important seasonal ranges connected by narrow corridors. Migration between ranges appear to be driven by winter conditions, thus, the timing of the movements is highly variable. The herd has high fidelity to these corridors, which elevates the importance of research and management efforts to conserve them. During the summer, these pronghorn inhabit large grasslands in and around Garland Prairie. During...
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 Mendocino mule deer herd complex is comprised of three overlapping black-tailed deer (Odocoileus hemionus columbianus) administrative herds, including Mendocino, Clear Lake, and Alder Springs. Mendocino black-tailed deer exhibit variable movement patterns and strategies, including traditional seasonal migrants, full-time residents, and multi-range migrants. Migrants move between seasonal ranges from a multitude of lower elevation areas within the North Coast Range in winter to higher elevation summer ranges (fig. XXX). Local biologists predict high-use winter ranges throughout both foothill slopes and valley bottoms. Female deer of the Mendocino herd complex exhibit both short-term (seasonal/annual) and long-term...

The Klickitat mule deer herd inhabits the Columbia Hills and surrounding terrain to the north along the Columbia River, Washington (fig. 23). The Klickitat River is the western boundary of the herd and is part of a transition zone between black-tailed deer and mule deer distributions. Habitats in the western half of the herd’s range include Quercus garryana (Oregon white oak) mixed with Abies spp. (fir), pine, or grassland species. The western half of the herd’s range comprises a mix of public and private lands, including rangeland, farmland, and the Klickitat Wildlife Area, which has protected crucial winter range since the 1950s. Sagebrush steppe is more prevalent in the eastern half of the herd’s range with Quercus...

The Owl Creek elk herd, with 7,500–8,500 wintering elk, inhabits the northwest corner of the Wind River Reservation, traversing habitats along the Absaroka Range and the Owl Creek Mountains (fig. 36). The herd contains resident and migratory elk; migrants travel an average 10.7 mi (17.2 km) one way. Elevations range from 6,000 ft (1,829 m) at Wind River near Crowheart to 12,200 ft (3,700 m) in the Absaroka Range, and summits in the Owl Creek Mountains reach 8,000–9,800 ft (2,438–2,987 m). Habitats range from sage and desert scrub in the lowlands surrounding the Wind River Range to upland meadows, aspen groves, Pinus contorta (lodgepole pine) forests, and alpine tundra. When on the Wind River Reservation, the elk...

The Colockum elk herd inhabits a mix of public and private lands northeast of Ellensburg between Blewett Pass of the Cascade Range and west of the Columbia River (fig. 35). The population ranges between 4,000 and 5,000 animals and is partially migratory, with individuals displaying a mix of resident (63 percent of analyzed individuals) and migratory (34 percent of analyzed individuals) behaviors. During winter, many elk inhabit grassland, sagebrush, antelope bitterbrush, and ponderosa pine habitats in the Whiskey Dick, Quilomene, and Colockum Wildlife Areas and the eastern reaches of the Naneum State Forest. As spring green up of vegetation nears, migratory elk travel northwest toward summer ranges in the Wenatchee...

Most of the Southeast mule deer herd winters along the Owyhee River in regions containing sagebrush communities and Columbia Basin grassland mixed with non-native annual grasslands. These mule deer either migrate west to summer ranges on Road Canyon and Gravel Ridges or east to the Owyhee Mountains along the Idaho border, with one mule deer migrating as far as Bald Mountain, 38.3 mi (61.6 km) into Idaho. Summer ranges feature shrubland, Columbia Basin grasslands, western juniper, and evergreen forests. In 2014, the Buzzard Complex fires burned 398,596 acres (161,306 ha), including Road Canyon, allowing medusahead and other non-native grasses to invade areas with originally low perennial plant abundance. Five mule...

The winter ranges of the Northside mule deer herd can be broadly separated into northern and southern subgroups. The majority of the southern subgroup winters at low elevations near the John Day River in areas dominated by big sagebrush communities, Columbia Basin grasslands, and western juniper. The northern subgroup is more spatially dispersed, wintering by Cottonwood Creek, the North Fork John Day River, and the Middle Fork John Day River in ranges containing more conifer forest than those of the southern subgroup. Both subgroups summer in the same general area, migrating either northeast or southeast to reach ranges featuring mixed-conifer, Picea spp. (spruce), Ponderosa pine, and western juniper forests with...
The Egg Lake Rocky Mountain elk (Cervus canadensis nelsoni) sub-herd range extends northeast from the town of McCloud around Ash Creek to the Big Valley Mountains and as far east as Highway 139 near the community of Hackamore. During the winter, this sub-herd primarily resides to the east of Big Valley Mountains near Egg Lake in Modoc County, California. They migrate east to private timberlands and spend the spring and summer just outside of McCloud, California. Topography of this area is relatively flat, but gradually transitions to steeper slopes around creeks, and typical habitat includes Ponderosa pine (Pinus ponderosa), Sierran mixed conifer, and montane hardwood conifer forests. Another sub-herd is known to...
The elk (Cervus canadensis) of the Jemez herd reside primarily in and around the Valles Caldera National Preserve, west of Los Alamos, NM and along the mesa tops to the north and west of the Valles Caldera. The area has experienced two wildfires, the stand replacing Las Conchas Fire and the mixed severity Thompson Ridge fire, within the last decade, burning a total of 180,555 acres. The data used in this report was collected to examine the responses of elk to these wildfires and forest restoration treatments. The Jemez herd is only partially migratory, with residents that consistently remain on the Valles Caldera and individuals that travel to the surrounding lower elevation slopes depending on the year and snowpack...
The mule deer (Odocoileus hemionus) of the Jemez Springs herd winter in the southwestern Jemez Mountains, south and east of the town of Jemez Springs. The area has experienced two severe wildfires, the Las Conchas and Thompson Ridge fires, within the last decade, burning a total of 180,555 acres. The data used in this report was collected to examine the responses of mule deer to these wildfires and forest restoration treatments. The winter range is located among the foothills of the Jemez Mountains, consisting primarily of pinyon-juniper woodlands. Individuals migrated an average of 26.1 miles, either to the western edge of the Jemez Mountains, near Blue Bird Mesa, or to the Valles Caldera. The central migration...
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 San Francisco Peaks mule deer (Odocoileus hemionus) herd makes one of Arizona’s most extraordinary annual migrations between Flagstaff, AZ and the Grand Canyon. The migration begins on summer range in GMU 7, where an estimated 5,300 mule deer reside. Their summer habitat contains alpine, subalpine, and ponderosa pine forests mixed with open grasslands and meadows. Beginning in October, a portion of the herd migrates north to GMU 9 to winter range along the South Rim containing pinyon-juniper, ponderosa pines, sagebrush, and cliffrose habitat. Through funding from Secretarial Order 3362, the Arizona Game and Fish Department (AZGFD) began a GPS collar study beginning in June of 2019. A total of 46 mule deer have...

Migratory mule deer (Odocoileus hemionus) within the San Joaquin Watershed occupy most of the watershed above Kerckhoff Reservoir, Fresno and Madera Counties, California. Human infrastructure in the watershed is widespread and includes residential, water control, hydroelectric power, and recreational use developments. Steep topography between winter and summer range limit crossing points along the San Joaquin River. Habitat conditions favoring deer declined from a peak around 1950, resulting in a reduction in the deer population. The current deer population is believed to be about 4,000. A massive wildfire burned through most of the watershed in 2020, dramatically changing habitat conditions in some areas. These...
