Anabat II detector with microphone on 1.5 m pole oriented straight down toward a reflector plate angled at 45 degrees. The detector was placed near the edge of a patch of conifers and directed toward the surrounding coastal grassland and abandoned nursery lands. The objective of this detector was simply to characterize species composition and activity levels throughout the year.

The Green Wave Hypothesis posits that herbivore migration manifests in response to waves of spring green-up (i.e., green-wave surfing). Nonetheless, empirical support for the Green Wave Hypothesis is mixed, and a framework for understanding variation in surfing is lacking. In a population of migratory mule deer (Odocoileus hemionus), 31% surfed plant phenology in spring as well as a theoretically perfect surfer, and 98% surfed better than random. Green-wave surfing varied among individuals, and was unrelated to age or energetic state. Instead, the greenscape, which we define as the order, rate, and duration of green-up along migratory routes, was the primary factor influencing surfing. Our results indicate that...

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...
Interest in the movement of pronghorn south of Arizona’s Interstate 40 (I-40) began when telemetry data from 1999 – 2004 showed seasonal round-trip movements upwards of 100 miles. In 2018, high-resolution GPS location data confirmed persistence of this remarkable pronghorn migration. This herd resides primarily in Game Management Unit 8, which had a population estimate of 400 individuals in 2019. Unlike traditional summer-winter range dynamics, this pronghorn population uses a complex of several important seasonal ranges during their annual movements, which are connected by narrow corridors. The herd has high fidelity to these corridors, which elevates the importance of research and management efforts to conserve...
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...

Natural river channels continually evolve and change shape over time. As a result, channel evolution or migration can cause problems for bridge structures that are fixed in the flood plain. A once-stable bridge structure that was uninfluenced by a river’s shape could be encroached upon by a migrating river channel. The potential effect of the actively meandering Wabash River on the Interstate 64 (I–64) Bridge at the border with Indiana near Grayville, Illinois, was studied using a river migration model called RVR Meander (RVR Meander, 2011). RVR Meander is a toolbox that can be used to model river channel meander migration with physically based bank erosion methods. This study assesses the Wabash River meandering...

Anabat II detector mounted on a 3m pole oriented straight down toward a reflector plate angled at 45 degrees. The detector was placed on the edge of cow pasture along a dense patch of riparian vegetation along North Jacoby Creek, near Arcata, Califoria. The objective of this detector was to determine species presence and activity levels throughout the year and to correlate them with weather variables from the Eureka Woodley Island weather station and compare to a similarly situated detector in McKinleyville, CA.

Anabat II detector with microphone on a 3m pole oriented straight down toward a reflector plate angled at 45 degrees. The detector was placed right along Bull Creek in fairly, dry (in the fall) open habitat. The objective of this station was to characterize activity levels and changes in them over the fall season... especially for migratory tree bats.

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 corridors for mule deer in the Doyle population...
