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 Dubois herd make several long-distance migrations into the heart of the Greater Yellowstone Ecosystem (fig. 26). These migrations originate from winter range in the warm, protected sagebrush valley surrounding Dubois, Wyoming, and extend to the southeast on the Wind River Reservation. Each spring, an estimated 6,000–7,000 deer leave this valley and the Reservation and migrate northwest. These journeys, averaging 44 mi one way, begin as deer ascend Togwotee Pass (9,658 ft [m 2,944] in elevation). From there, they cross challenging natural terrain with high mountain passes and disperse into the north Wind River Range, Gros Ventre Range, Absaroka Range, Grand Teton National Park, and deep into...
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...

This dataset is a polygon shapefile delineating the footprint of bathymetric data collected in October, 2021 for an approximately 500 meter (m) reach of the Kalamazoo River upstream of Plainwell, Michigan (MI). Bathymetric data in the river channel were collected with a single beam sonar and Acoustic Current Doppler Profiler operated along 2 longitudinal transects and 48 cross-sectional transects, respectively.
The Loyalton mule deer (Odocoileus hemionus) herd winters west and northwest of Reno, Nevada along the California-Nevada border, extending into the Peterson Mountains, east of Highway 395 in Nevada. A portion of the herd also winters north of I-80 on Peavine Mountain in Nevada. This population represents an interstate migratory herd but also contains year-round residents in both states. Deer migrate southwest into the Sierra Nevada Mountains of California on both sides of Highway 89 from Truckee to Sierraville, mostly staying north of I-80 and into the Tahoe National Forest. Significant challenges include urban development, vehicle collisions on Highways 89, 395, and I80, and large-scale wildfires that have burned...
Mule deer (Odocoileus hemionus) of the Kaibab Plateau in Arizona had a population estimate of 10,200 individuals in 2019. The herd is relatively isolated; limited in range to the east, south, and west sides by the Grand Canyon. Annually the Kaibab herd migrates an average of 27 mi (43 km) between summer and winter range. Winter range is along the west, east, and northern extents of the plateau; consisting of pinyon-juniper woodlands mixed with sagebrush, cliffrose, bitterbrush, and various grasses. Some of the Kaibab herd winters in Utah, sharing winter range with Utah’s Paunsaugunt Plateau herd. During migration mule deer pass through mid-elevation transitional range containing Gambel oak, pinyon pine, and Utah...
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...
The mule deer (Odocoileus hemionus) of the Pueblo of Santa Ana herds are primarily non-migratory, with two distinct winter ranges separated by U.S. Route 550. The winter ranges consist primarily of Chihuahuan semi‐desert grassland, dominated by black grama (Bouteloua eriopoda), galleta (Pleuraphis jamesii), mesa dropseed (Sporobolus flexuosus), and fourwing saltbush (Atriplex canescens), with higher elevation sections consisting of pinyon-juniper woodland and juniper savannah. There was no movement between the two winter ranges, with only individuals from the winter range northeast of US 550 crossing the highway west of the Jemez Canyon Reservoir. Two individuals from the winter range northeast of US 550 migrated...
The Sheldon-Hart Mountain pronghorn (Antilocapra americana) herd is part of a large interstate metapopulation distributed across northwest Nevada, southeast Oregon, and portions of northeast California. Some animals travel up to 100 miles between summer and winter ranges and traverse multiple federal land jurisdictions, including the Sheldon National Wildlife Refuge, Hart Mountain National Wildlife Refuge, and surrounding Bureau of Land Management (BLM) lands. The herd can be characterized as conditionally or partially migratory with approximately 65% of collared animals exhibiting migratory tendencies. Major summer ranges include portions of the Hart Mountain Wildlife Refuge, Sheldon National Wildlife Refuge, and...
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,...

From 2013 to 2015, bathymetric surveys of New York City’s six West of Hudson reservoirs (Ashokan, Cannonsville, Neversink, Pepacton, Rondout, and Schoharie) were performed to provide updated capacity tables and bathymetric maps. Depths were surveyed with a single-beam echo sounder and real-time kinematic global positioning system (RTK-GPS) along planned transects at predetermined intervals for each reservoir. A separate set of echo sounder data was collected along transects at oblique angles to the main transects for accuracy assessment. Field survey data was combined with water-surface elevations in a geographic information system to create three-dimensional surfaces representing reservoir-bed elevations in the...
