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...

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,...

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...

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...

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...
