Migration Stopovers of Elk in the Jemez Herd in New Mexico

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 levels. The most consistent migration during  winter was south towards Bandelier National Monument, while a few individuals migrated east to the Santa Clara Indian Reservation or west to Lake Fork Mesa. Moreover, while most individuals returned to the Caldera in the early spring, some migrated north to the higher elevations of the La Grulla Plateau. These migrations were relatively short, averaging only 14 miles with the longest only reaching 28 miles. The Caldera contains a mix of ponderosa pine forests, mixed-conifer forests, and open grasslands, while the lower elevation slopes are predominantly pinyon-juniper woodlands. The primary challenge for individuals migrating would be crossing NM State Route 4 when traveling to Bandelier National Monument.
These data provide the location of migration stopovers for elk from the Jemez Herd in New Mexico. They were developed from Brownian Bridge movement models using 61 migration sequences collected from a sample size of 24 adult elk comprising GPS locations collected every 5 or 6 hours.

Migration Routes of Elk in the West Goose Lake Herd in California

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 US Forest Service. Additionally, although the core migration route does cross Highway 140, little to no impacts are known to exist from this crossing.
These data provide the location of migration routes for elk in the West Goose Lake population in California and Oregon. They were developed from 25 migration sequences collected from a sample size of 12 animals comprising GPS locations collected every 4-8 hours.

Winter Ranges of Elk in the Egg Lake Herd in California

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 exist on the east side of Highway 139 near Clear Lake and this may present a barrier between the two sub-herds as some mortality has been documented on the highway, but the full extent of this is unknown.
These data provide the location of winter ranges for elk in the Egg Lake population in California. They were developed from 17 winter sequences collected from a sample size of 9 animals comprising GPS locations collected every 3-8 hours.

Winter Ranges of Elk in the East Shasta Valley Herd in California

The East Shasta Valley sub-herd of Rocky Mountain elk (Cervus canadensis nelsoni) spend most of their time on private ranchlands in Shasta Valley in the winter. This area offers patches of oak woodlands and grasslands on gentle slopes. In the spring, elk migrate to their summer range around Grass Lake, Bull Meadows, and Deer Mountain where the habitat is primarily characterized by mixed conifer timber stands of Ponderosa pine (Pinus ponderosa), lodgepole pine (Pinus contorta) and Douglas fir (Pseudotsuga menziesii). The meadows around Grass Lake seem especially important to this sub-herd, as neonatal calves have been documented in this area since at least 1984 (Fischer 1987). Some animals from this sub-herd migrate into Oregon or move eastward to other sub-herds, but Highway 97 presents a significant barrier to this movement with many documented vehicle collisions between Horsethief Creek, and Grass Lake Summit. A wildlife crossing is proposed for this area to promote habitat connectivity and wildlife movement.
These data provide the location of winter ranges for elk in the East Shasta Valley population in California. They were developed from 27 migration sequences collected from a sample size of 14 animals comprising GPS locations collected every 3-8 hours.

Winter Ranges of Mule Deer in the Carson River Herd in California and Nevada

A significant portion of the interstate Carson River herd summers in the Sierra Nevada range of California and migrates to a winter range near the California-Nevada border. Herd size has declined significantly (&gt;70%) from historical peak levels, likely due to habitat loss and vehicle collisions. A large increase in housing development and traffic along the Highway 395 corridor during the past 20 years has contributed to population declines for this herd. Significant barriers include fencing along Carson River and outlying suburban areas in Carson City, Minden, and Gardnerville, Nevada.
These data provide the location of winter ranges for mule deer (Odocoileus hemionus) in the Carson River population in California and Nevada. They were developed from 92 winter sequences collected from a sample size of 48 animals comprising GPS locations collected every 2-12 hours.

Winter Ranges of Elk in the San Francisco Peaks Herd in Arizona

The San Francisco Peaks elk (Cervus canadensis) herd comprises a migratory portion of the larger herd units in Arizona’s Game Management Units (GMU) 7 and 9. GMU 7 and 9 had a combined population estimate of 5,200 in 2019. These data were generated from two elk research projects by the Arizona Game &amp; Fish Department: one to assess elk-vehicle collisions on Interstate 40 (Gagnon et al. 2012) and the other to evaluate aerial survey methods for elk abundance (Bristow et al. 2019). While many of the elk reside in the same general areas year-round, the migratory portion of this herd migrates an average of 42 miles between summer and winter range. Summer range, primarily in GMU 7, consists of high elevation open meadows and ponderosa pine forests around the San Francisco Peaks and Kendrick Park. Winter range contains a mix of ponderosa pine, pinyon-juniper, and sagebrush habitats along the Coconino Rim and Upper Basin. Obstacles to migration for this herd are predominantly roads including State Route 64 and U.S. Highway 180.
These data provide the location of winter ranges for elk from the San Francisco Peaks Herd in Arizona. They were developed using 6 winter range sequences collected from a sample size of 6 adult elk comprising GPS locations collected every 3-7 hours.

Winter Ranges of Elk in the Pueblo of Santa Ana Herd in New Mexico

The elk (Cervus canadensis) of the Pueblo of Santa Ana herd are primarily non-migratory and located northeast of U.S. Route 550 and south of the Jemez Mountains. The winter range is dominated by black grama (Bouteloua eriopoda), galleta (Pleuraphis jamesii), mesa dropseed (Sporobolus flexuosus), and fourwing saltbush (Atriplex canescens), with pinyon-juniper woodlands and ponderosa pine forests dominating the higher elevation slopes of the Jemez Mountains. Two individuals exhibited migratory movements from the lower elevation winter range on the Pueblo of Santa Ana to the higher-elevation slopes of the Jemez Mountains via Bear Springs Canyon, east of the town of Ponderosa. Challenges to elk movement include the winter range being bounded by U.S. Interstate 25 to the southeast and US 550 to the southwest, with elk only crossing US 550 west of the Jemez Canyon Reservoir.
These data provide the location of winter ranges for elk from the Pueblo of Santa Ana Herd in New Mexico. They were developed from Brownian Bridge movement models collected from a sample size of 9 adult elk comprising GPS locations collected every 4 hours.
