The North of Interstate 40 Pronghorn herd primarily resides in Arizona’s Game Management Unit (GMU) 7. GMU 7 had an estimated population of 550 pronghorn in 2019. The Pronghorn North of Interstate 40 summer in high elevation open meadows and ponderosa pine habitat near Government Prairie. When winter conditions set in the pronghorn Antilocapra americana) seek lower elevations, migrating through mixed pinyon-juniper woodlands to open grassland and shrub habitats north of Sitgreaves Mountain, often crossing US Highway 180 (US-180) towards Antelope Flat. US-180 is an increasing threat to this migration corridor as traffic volumes rise. However, right-of-way fence improvements and relatively low traffic volumes on US-180...

Pronghorn (Antilocapra americana) within the Sublette herd comprise one of the largest pronghorn populations in North America. Sublette pronghorn winter in the more southern areas of the upper Green River Basin. Depending upon winter severity, individual pronghorn winter between Pinedale in the north to Rock Springs in the south, and in the western portions of the Red Desert. Winter ranges include a mix of grassland and sagebrush dominated mesas and rolling hills. During migration, animals that have been tracked with GPS collars (n = 362 females) travel an average one-way distance of nearly 60 miles (96 km), with some animals migrating over 200 miles (320 km). This herd is home to the longest distance migrating...

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 (>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...

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 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 stopovers for mule deer in the Doyle population...

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...

With substantial forest habitat in the Sierra Madre, the Sierra Madre elk population is one of the most productive elk herds in the state. The herd occupies typical year-round habitat for elk in Wyoming. They winter largely in expansive sagebrush growing in the foothills and at low elevations in the valley of the Little Snake River and its various drainages. In spring, most animals migrate to higher elevation forested habitat within the Sierra Madre. Like many elk herds, their seasonal migrations tend to be diffuse without a clear delineation of narrowly defined corridors; the average migration length is approximately 25 miles. Some animals migrate farther distances, with a maximum length of 62 miles, south across...

The South Rock Spring mule deer herd lives year-round in the Greater Little Mountain Ecosystem in southwestern Wyoming, an arid landscape where desert badlands give way to aspen and mountain shrub communities at higher elevations. Approximately 4,000 mule deer occupy this landscape, which is one of the least developed in Wyoming. Likely owing to its aridity and lack of strong elevational gradients and high mountains, mule deer migrations in this herd are less pronounced and less structured than elsewhere in Wyoming. Instead of all animals congregating in a common winter range and following a common narrow corridor to their summer range, mule deer in this herd migrate in a very diverse fashion. Some animals winter...

These data were compiled to monitor native fishes (particularly humpback chub Gila cypha) in the Little Colorado River, in the Grand Canyon, AZ. Objective(s) of our study were to evaluate the timing of native fish migration and the abundance of migratory and resident fishes between the Colorado and Little Colorado Rivers in the Grand Canyon. These data represent encounter histories for fishes - including array detections and physical captures. These data were collected in the lower 13.56 river kilometers of the Little Colorado River in April and May of 2021 and 2022. These data were collected by U.S. Fish and Wildlife Service (physical captures) and U.S. Geological Survey (array detections). These data can be used...
The main contents of this data release are estimates of daily and annual abundances of federally-threatened natural-origin age-0 fall Chinook salmon (Oncorhynchus tshawytscha) passing Lower Granite Dam, Washington. Fish from this population are sampled as they pass Lower Granite Dam, but these sample data cannot be used directly to infer abundance because capture probability at Lower Granite Dam varies throughout the migration and because of the contemporaneous presence of unmarked hatchery-origin fish which are visually indistinguishable from natural-origin fish. Estimates of abundance were obtained by fitting a statistical mark-recapture model that integrated four related datasets: 1) the release/recapture data...

The banding data provides a comprehensive list of where and when each of the 21 golden eagles were captured, tagged (all satellite-tagged, some also radio-tagged) and deployed. The banding data is organized into a spreadsheet (Banding_Records.csv) that provides basic information on each bird as well as any notes about recaptures or deaths. The Capture_Sheets.pdf is a supplemental document that provides more detailed biological and spatiotemporal information about 15 of the tagged individuals. Individual golden eagles can be identified across the three datasets with their unique and consistent PTT numbers.

This data set contains mark-recapture information for individuals of Dicamptodon tenebrosus and Ascaphus truei marked for individual recognition. Amphibians represented in this data set were captured in 14 first-order perennial and seasonally intermittent streams in the East Fork of the South Fork of the Trask River in the northern Oregon Coast Range. Individuals are larval and mature aquatic Dicamptodon tenebrosus and larval Ascaphus truei. Of the Ascaphus truei larvae only individuals thought to be in their first summer when first captured are included (these are individuals whose knees had yet to emerge from under the anal flap or fold).

The satellite data consist of 9,253 estimated locations of 21 golden eagles (Aquila chrysaetos) that were satellite-tagged in either east-central Idaho (Salmon, Idaho) or southwestern Idaho (Snake River National Conservation Area) and tracked between 1993 and 1997 via the Argos satellite system. The raw eagle tracking data provided by Argos were filtered one time using a version of the Douglas Argos-Filter Algorithm and converted into XLS spreadsheet form. This preservation project preserved the geospatial and satellite information from the XLS spreadsheet and released it in shapefile format (Satellite_Data.shp) and CSV format (Satellite_Data.csv). Each tagged bird in this dataset has a unique PTT number that is...

The whooping crane (Grus americana) is a listed, endangered species in North America, protected under federal legislation in the United States and Canada. The only self-sustaining and wild population of Whooping Cranes nests at and near Wood Buffalo National Park near the provincial border of Northwest Territories and Alberta, Canada. Birds from this population migrate through the Great Plains of North America and spend a nonbreeding period along the Gulf Coast of Texas at Aransas National Wildlife Refuge and surrounding lands. These data represent predictions from a resource selection function using GPS locations between 2010 and 2016 during migration. This surface is a composite of drought and non-drought conditions...

These map files are meant to provide a common spatial representation of the mapped migrations. This data release provides the means for ungulate migrations to be mapped and planned for across a wide variety of landscapes where they occur. Due to data sharing constraints of participating agencies, not all the files that underlie the mapped migrations included in the report have been released. Data can be viewed at: https://westernmigrations.net. Data in this archive can be downloaded two ways. To download...
Elk within the Jackson herd have been the focus of management for over a century. The herd, which numbers between 9,000 -13,000, winters in Jackson Hole. Most of the herd winters in the sagebrush basins and irrigated fields of the National Elk Refuge, with less than a quarter of the herd wintering in the Gros Ventre drainage to the east. Migrating animals travel an average one-way distance of 39 miles, with some migrating as far as 168 miles. The herd is partially migratory, containing both migrant and residents. In spring, the migrants move north on either side of Jackson Lake, into the eastern foothills of the Teton Range and into the upper drainages of the Snake River and the southern portion of Yellowstone National...

The Baggs Mule Deer Corridor was officially designated by the Wyoming Game and Fish Department (WGFD) in 2018 (fig. 24). The Baggs Herd is managed for approximately 19,000 animals, and the corridor is based on two wintering deer populations: a northern and southern segment. Animals in the north segment occupy a relatively small winter range along a pinyon-juniper ridge that runs along the east side of Highway 789. From there, deer migrate north and west to summer ranges on Atlantic Rim, the Sand Hills, and the head of Savery Creek. The southern segment occupies a larger sagebrush winter range on both sides of Highway 789, some of which extends into Colorado. These animals migrate north and west to summer ranges...

The Interstate 17 (I-17) elk herd primarily resides in Arizona’s GMU 6A and 11M south of Flagstaff. The population estimate for elk in GMU 6A was 6,500 in 2019. Their summer range consists of gentle topography with ponderosa pine forest and interspersed riparian-meadow habitat. Annually, the I-17 elk herd migrates an average of 24 miles to lower-elevation winter range dominated by pinyon-juniper habitat. This winter habitat is located along Oak Creek Canyon to the west and Wet Beaver Creek to the south. The I-17 elk herd faces high road mortality, averaging around 80 mortalities from vehicles per year (Gagnon et al 2013). Despite the high incidence of elk-vehicle collisions along I-17, road crossings are generally...

In 2008, 13 mule deer were GPS collared near the South Rim of the Grand Canyon to understand the impact of Arizona’s State Route 64 on mule deer movement. Unexpectedly, 4 individuals migrated over 50 miles to summer range near the San Francisco Peaks, north of Flagstaff, containing alpine, subalpine, and ponderosa pine habitats. The GPS collars dropped in 2009, but questions surrounding this long-distance migration remained. In June of 2019, the Arizona Game and Fish Department GPS collared 20 mule deer from the San Francisco Peaks herd on their summer range in Game Management Unit 7E/7W, where an estimated 5,300 mule deer reside. The primary challenges to mule deer in this migration corridor are related to navigating...
