Observations of irrigated agricultural land within the Hualapai Valley Groundwater Basin in Arizona. Digitized field boundaries were used to locate crops for in situ verification once in 2022; crop verification occurred on June 2nd. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program County Mosaic 2021 imagery for Arizona and supplemented with Landsat and Sentinel2 imagery collections accessed via the Sentinel Hub, Sentinel Playground (https://apps.sentinel-hub.com/sentinel-playground). Satellite images were also used to identify the length of the growing season and crop condition. Water withdrawals were calculated using the modified Blaney-Criddle model of...

Samples of vein-type magmatic-steam alunite were collected over several field seasons from five mines and prospects (L&N, Mt. Edna, Christmas, upper Mineral Products, and Close In) in the Alunite Ridge and Deer Trail Mountain area, Marysvale, Utah, as well as a sample from the Deer Trail mine workings from which sericite was separated. The magmatic-steam alunite and sericite were analyzed by the 40Ar/39Ar method to constrain the timing and duration of magmatic activity associated with the intrusion of two porphyry stocks beneath Alunite Ridge and Deer Trail Mountain. In addition, a sample of a highly altered rhyolitic quartz porphyry dike was collected from the upper Mineral Products mine, from which zircons were...
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...
The Paunsaugunt Plateau in southern Utah is home to around 5,200 mule deer (Odocoileus hemionus). Ongoing research by the Utah DWR has continued to shape our understanding of their annual migration. In contrast to the Volume 1 report (Kauffman et al. 2020), the Paunsaugunt Herd in this Volume includes the addition of 25 individual mule deer, 127 migrations, and 161 winter range sequences. Beginning in early October the mule deer migrate south an average of 36 mi (58 km) to winter range along the Utah-Arizona border. Approximately 20–30 percent of the Paunsaugunt Plateau herd reside in northern Arizona during the winter, sharing winter range also used by deer from Arizona’s Kaibab Plateau herd. Beginning around mid-April,...
The Jawbone Ridge mule deer (Odocoileus hemionus) herd is a sub-herd of the Tuolumne herd, which migrate to the Jawbone Ridge flats in the winter in Tuolumne, Mariposa, and Alpine Counties. Additionally, a small sample of deer were captured from the Yosemite herd to determine herd overlap. GPS collars were normally set to take a location every 7 hours, and emit a signal Monday through Friday, 9am to 5pm. Some GPS collars were set to take a location fix every hour during periods of time when deer were thought to be migrating (May and November). The most important portion of the winter range is the Jawbone ridge flats, situated at an elevation of 4,000 feet. Deer migrate from here east into the high Sierra Nevada...
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...

Little information exists regarding demographic rates and abundance of elk in the Marble Mountains in California. In the early 1990s and 2000s, elk were reintroduced from Oregon into the Marble Mountain area (CDFW, 2018). Since then, elk have reestablished throughout much of the area, but GPS collar data and information on movement are limited. Current research examines how fire influences elk occupancy in the area. Elk were collared from 2006 to 2013, at sites in the Klamath National Forest and Marble Mountain Wilderness in the north, and close to Cecilville in the Shasta-Trinity National Forest in the south. After collaring, elk were separated into three distinct sub-herds (north: Ukonom, central: Wooley Creek,...

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 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 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 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...

Along the eastern slope of the Cascade Mountains in Chelan and Kittitas counties, the Wenatchee Mountains mule deer herd inhabits a matrix of private and public lands. Historically, the Wenatchee Mountains mule deer were separated into two sub-herds, Chelan and Kittitas; however, recent movement data from GPS-collared individuals associated with Secretarial Order 3362 (Department of the Interior, 2018) revealed that the mule deer south of U.S. Highway 2 and north of Interstate 90 represent one population. Their high-use winter range extends along the foothills west and south of Wenatchee, Washington and throughout the foothills of the Kittitas Valley outside Ellensburg, Washington. The low-use winter range occurs...

In 2012, Hurricane Sandy struck the Northeastern US causing devastation among coastal ecosystems. Post-hurricane marsh restoration efforts have included sediment deposition, planting of vegetation, and restoring tidal hydrology. The work presented here is part of a larger project funded by the National Fish and Wildlife Foundation (NFWF) to monitor the post-restoration ecological resilience of coastal ecosystems in the wake of Hurricane Sandy. The U.S. Geological Survey Woods Hole Coastal and Marine Science Center made in-situ observations during 2018-2019 and 2022-2023 at two sites: Thompsons Beach, NJ and Stone Harbor, NJ. Marsh creek hydrodynamics and water quality including currents, waves, water levels, water...

Wild insect pollination has significant positive effects on pollinator-dependent crop production. While managed honeybees are often used to provide pollination to pollinator-dependent crops, visits by wild insect pollinators have been shown to be more effective in increasing fruit set than managed pollinators, and wild insect pollination increases fruit set even when managed pollinator visitation is high (Garibaldi et al. 2013). The total value of the pollination services provided by wild, native insects has been estimated at $3.07 billion annually (2003 dollars) in the United States (Losey & Vaughan 2006). To assess the spatial distribution of potential wild insect pollination, we mapped the supply of potential...
