The Mount Dome pronghorn herd contains a mixture of residents and short distance, elevation-based migrants, but this herd does not migrate between traditional summer and winter seasonal ranges. Instead, much of the herd displays a somewhat nomadic migratory tendency, slowly moving up or down elevational gradients. Long distance movements from this herd are rare since it is largely surrounded by geographical and anthropogenic features with low permeability to movement. Some individuals used higher elevation areas throughout the summer, though this pattern was not ubiquitous. Therefore, annual home ranges were modeled using year-round data to demarcate high use areas (fig. XXX). Drought, increasing fire frequency,...
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 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 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...
Elk (Cervus elpahus canadensis) within the western section of the Bighorn Mountains display altitudinal migration. In the spring, they migrate from the western foothills up into the mountains, and in the fall, they head back down to lower elevations (fig. 70). The herd, which numbers around 2,700, winters along the western foothills of the Bighorn Mountains along the eastern section of the Bighorn Basin. Winter ranges are a mix of shrubs and herbaceous grasslands, largely supported by private and BLM land, though many individuals will remain within the boundaries of the Bighorn National Forest. During migration animals travel an average one way distance of 20 mi (32 km) ranging from as little as 5 mi (8 km) to as...
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 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...

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....

The Selkirk White-tailed Deer Management Zone (WDMZ) is home to the largest population of white-tailed deer in the state and consists of seven Game Management Units (GMU; GMUs 105, 108, 111, 113, 117, 121, and 124) located in northeast Washington. Aside from the southern portion of GMU 124, dominated by the metropolitan area of Spokane, Washington, most of these GMUs have similar rural characteristics. Private landowners manage most of the Selkirk WDMZ (77 percent), primarily for commercial timber harvest. The U.S. Forest Service manages 16 percent of the land, and the U.S. Fish and Wildlife Service, Department of Natural Resources, and Bureau of Land Management manage the remaining 7 percent. White-tailed deer...

The Crow Mesa Mule Deer Study was initiated in 2019 to identify the seasonal movement and distribution patterns of mule deer in the eastern half of Game Management Unit (GMU) 2C. This GPS study builds on nearby studies of mule deer and elk conducted by the Bureau of Land Management, the Southern Ute Tribe, the Jicarilla Apache Nation, and the New Mexico Department of Fish and Game. Migration corridors extended 20 to 75 miles from the winter ranges in GMU 2C to various summer ranges northeast to the Carson National Forest near Chama, and southeast to the San Pedro Parks Wilderness in the Santa Fe National Forest. The Crow Mesa herd relies largely on winter ranges administered by the Bureau of Land Management, where...
Mule deer (Odocoileus hemionus) within the Sheep Mountain herd winter in the East and Northeast foothills of the snowy range mountains in Southeastern Wyoming. The sheep mountain herd is mainly migratory with very few individuals staying on winter range year around. Winter ranges are a mix of grassland and sagebrush hills, often free of snow from wind. During migration, animals that have been tracked with GPS collars (n = 56 females) travel an average one-way distance of nearly 20 miles (32 km), with some animals migrating over 50 miles (80 km). The herd, which numbers around 7,600 has a variety of summer destinations. Some individuals migrate across the snowy range to the west. Others migrate into Colorado, summering...

We conducted two literature searches to help guide the development of a conceptual model of a barrier island and shoreline system in response to cumulative effects of restoration projects. The first search targeted examples of cumulative effects assessments and/or existing conceptual models from which a system-specific conceptual model can be built. The second search targeted the identification of barrier island and shoreline environmental system components, drivers and stressors. There are two data sheets in this dataset; one set of records from each literature search. Each spreadsheet includes record information pulled directly from the Web of Science searches, such as title, authors, abstract, and publication...

The greater sage-grouse (Centrocercus urophasianus: hereafter; sage-grouse) population in Modoc County California is geographically isolated and has been subsidized by translocation to prevent inbreeding depression since 2005. Despite significant efforts to increase the population through translocations and habitat improvement by cutting encroaching western juniper (Juniperus occidentalis), only a single lek remains (from 56 in the 1940s). Since 2017, several large wildfires have occurred within the landscape that led to an increase in invasive grasses and a decrease in sagebrush (Artemisia sp.) cover that has further degraded important nesting and brooding habitat. The data collected consists of monthly encounter...

Hair samples were collected in discrete areas during radio-collar studies in Vermont under the auspices of University of Vermont IACUC protocol #17-035 (n=106), New Hampshire (n=34), and Maine (n=57). Hair and tissue samples were opportunistically collected from animals that were harvested, died in vehicle collisions, or translocated throughout Vermont (n = 105), Quebec (n = 198), Massachusetts (n = 5), and New York (n = 24). Of the 317 previously identified autosomal moose SNPs, 136 loci were utilized to develop a MALDI-TOF MS genotyping assay. After filtering problematic loci and individuals, genotypes from 112 of 136 SNPs (82%) were obtained for 507 individuals and all loci met Hardy-Weinberg expectations in...

Translocating individuals of Eleutherodactylus frogs to alternative, suitable habitat is an adaptation strategy designed to minimize the impact of projected warming and drying in Puerto Rico. The action increases species persistence by increasing spatial redundancy, but it could also be used to supplement extant populations. We released 34 Eleutherodactylus coqui to determine initial, post-release survival under two treatments – non-translocated (N = 14), and translocated (N=20) to a different location 0.8 km away, but sharing similar habitat and environmental conditions. We defined “initial” as the first 17 days post-release, a period where we hypothesized that translocated individuals would have lower survival...
