The Doyle mule deer (Odocoileus hemionus) herd migrates from a winter range in Honey Lake Valley and Upper Long Valley near Doyle, California along US Highway 395 in Lassen County, California and eastward into Plumas County and Plumas National Forest in the Sierra Nevada Mountains for the summer. Winter range also exists on the Nevada side of the border in Washoe County. Much of the winter range habitat is now deteriorated, lacking vegetation that historically provided forage. Highway 395 is a major barrier to migration, with hundreds of deer being killed annually trying to cross it. Population estimates were ~15,600 in 2019. These data provide the location of migration routes for mule deer in the Doyle population...

The Downieville-Nevada City mule deer herd winters in the western foothills of the Sierra Nevada range. 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 herd migrates north and east of Nevada City on both sides of the middle fork of the Yuba River, staying north of Interstate 80, to high-elevation summer range along the crest of the Sierra Nevada. The summer range is primarily mixed conifer habitat opening up to high alpine granite near the crest of the Sierra Nevada. The population size is unknown due to limited survey capacity, but the population is considered stable to declining, affected primarily...

The East Tehama herd is the largest migratory population of mule deer in California (Hill and Figura, 2020). Population numbers peaked in the 1960s, but have declined in recent decades (Ramsey and others, 1981; California Department of Fish and Wildlife unpublished data). These mule deer migrate from a lower elevation winter range in the foothills east of the Sacramento Valley to upper elevation summer ranges in the southern Cascades and northern Sierra Nevada. Although portions of the herd winter on the California Department of Fish and Wildlife’s Tehama Wildlife Area and other public lands, the winter range also comprises many private ranchlands. The herd’s summer range includes significant portions of Lassen...

The Grizzly Flat herd winters in the western foothills of the Sierra Nevada near Grizzly Flats, California. The winter range includes conifer, vineyards, and oak woodland that is shared with a resident portion of the herd on a mix of private and public lands. In the spring, the Grizzly Flat herd migrates east to higher elevation terrain in the El Dorado National Forest, staying south of Interstate 50 and primarily north of U.S. Highway 88, to the crest of the Sierra Nevada. The summer range contains primarily mixed conifer opening up to high alpine granite near the crest of the Sierra Nevada. Although the population size of the Grizzly Flat herd is unknown due to limited surveys, it is considered stable to declining,...

The Manache mule deer herd contains both California mule deer (Odocoileus hemionus californicus) and Inyo mule deer (Odocoileus hemionus inyoensis). The herd predominantly covers the east slopes and crest of the Sierra Nevada. Elevation stretches from 3,200 ft on the Owens Valley winter range, to above 11,000 ft on the summer ranges in Sequoia National Park. The Manache herd migrates from winter ranges just west of U.S. Route 395 on the steep slopes and valleys of the Sierra Nevada near Dunmovin and Haiwee east to some of the highest elevations in the continental United States in Inyo and Sequoia National Forests. Deer numbers were very low by 1900, attributed largely to extreme overgrazing by domestic sheep and...
The Modoc Interstate mule deer (Odocoileus hemionus) herd migrates from a winter range near Clear Lake Reservoir in Modoc County, California north into Oregon in Klamath and Lake counties for the summer. Much of this herd likely resides in Oregon year-round as California population estimates (2000-3000) are lower than Oregon estimates (~15,000). Female mule deer were captured in Modoc in February 2017 and equipped with satellite collars manufactured by Lotek. Additional GPS data was collected between 1999-2001 from deer captured in 1999, and was included to supplement the small sample size of the 2017-2020 dataset. The data was collected with a priority to ascertain general distributions, survival, and home range,...

The winter range of the West Goose Lake Rocky Mountain elk (Cervus canadensis nelsoni) sub-herd is located north of Alturas and west of Highway 395 within the Devil’s Garden Ranger District of the Modoc National Forest. This area is characterized by juniper (Juniperus occidentalis) woodlands, and sagebrush flats with some stands of lodgepole (Pinus contorta) and ponderosa pine (Pinus ponderosa) throughout flat, rocky terrain. From this area, a portion of the herd migrates approximately 50 miles north into Oregon’s Fremont National Forest, habitat that primarily consists of lodgepole and ponderosa pine forests. Minimal barriers exist along this migration route since the corridor primarily occurs on land managed by...

The Kern River deer herd includes primarily California mule deer (Odocoileus hemionus californicus), but some Inyo mule deer (Odocoileus hemionus inyoensis) associate with California mule deer on the summer range. The population size peaked at 11,000 individuals in 1949, but in recent decades numbers have decreased to an estimated 3,500 deer in 1995 and 2,000 deer in 2001. The population size estimate is now, conservatively, approximately 4,000 individuals owing primarily to habitat expansion by the 2001 McNally Fire (California Department of Fish and Wildlife unpublished data). The Kern River herd winters in Sequoia National Forest north of Johnsondale and east of Slate Mountain. In the spring, they migrate northward...
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 Bucks Mountain-Mooretown mule deer herd winters in the western foothills of the Sierra Nevada. The winter range includes vernal pool grassland, oak woodland, and dense conifer that is shared with a resident portion of the herd on a mix of public and private lands. In the spring, the Bucks Mountain-Mooretown herd migrates along the U.S. Highway 70 corridor and high-elevation locations of the Sierra Nevada east and south to higher elevation terrain in the Plumas National Forest east of the Sierra Nevada near Quincy and La Porte, California. The summer range is primarily mixed conifer opening up to high alpine granite near the crest, and transitioning to a mix of conifer and shrub on the eastern side of the Sierra...

The Salt Springs herd winters in the western foothills of the Sierra Nevada predominantly on private property from Tylers Corner south to Sheep Ranch. The summer range is in high-elevation terrain near Lower Bear River Reservoir and Salt Springs Reservoir. The winter range consists of mainly oak woodland habitat and the summer range includes primarily mixed conifer opening up to high alpine granite near the crest of the Sierra Nevada. The population size is unknown due to limited data. This GPS collaring project was designed as part of a region-wide effort to obtain abundance estimates for deer using fecal DNA and home range analyses, with pinpointing migration routes and identifying winter ranges a secondary priority....
