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 them. During the summer, these pronghorn inhabit large grasslands in the Garland Prairie area. During migration, animals parallel I-40 westward moving through densely forested habitat, then grasslands near Ash Fork, and finally moving south to winter range near Drake, AZ. In late March the migration is reversed. High-volume roads including I-40 and State Route 89 present the largest impediments to movement for this migration. These roads also appear to determine the herd’s movement patterns along this corridor, as pronghorn rarely cross them. These data provide the location of annual ranges for pronghorn (Antilocapra americana) from the South of Interstate 40 herd in Arizona. They were developed from Brownian bridge movement models using 21 annual sequences collected from a sample size of 21 adult pronghorn comprising GPS locations collected every 3 hours. Across the western U.S., many ungulate herds must migrate seasonally to access resources and avoid harsh winter conditions. Because these corridors traverse vast landscapes (i.e., up to 150 miles), they are increasingly threatened by roads, fencing, subdivisions and other development. Over the last decade, many new tracking studies have been conducted on migratory herds, and analytical methods have been developed that allow for population-level corridors and stopovers to be mapped and prioritized. In 2018, the U.S. Geological Survey assembled a Corridor Mapping Team to provide technical assistance to western states working to map bison, elk, moose, mule deer, and pronghorn corridors using existing GPS data. Based out of the Wyoming Cooperative Fish and Wildlife Research Unit, the team consists of federal scientists, university researchers, and biologists and analysts from participating state agencies. In its first year, the team has worked to develop a standardized analytical and computational methods and a workflow applicable to data sets typically collected by state agencies. In 2019, the team completed analyses necessary to map corridors, stopovers, and winter ranges in Arizona, Idaho, Nevada, Utah, and Wyoming. A total of 26 corridors, 16 migration routes, 25 stopovers, and 9 winter ranges, were mapped across these states and are included in this project. The Ungulate Migrations of the Western United States report and associated map archive provides the means for corridors to be taken into account by state and federal transportation officials, land and wildlife managers, planners, and other conservationists working to maintain big game corridors in the western states. 20180101 20191201 observed In work Annually -112.4928 -111.6371 35.3212 34.7549 Flagstaff ISO 19115 Topic Category environment economy USGS Thesaurus migration migratory species animal behavior migration (organisms) USGS Metadata Identifier USGS:5f8db50782ce32418791d522 Common geographic areas Arizona United States Flagstaff None.

Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. No formal positional accuracy tests were conducted No formal positional accuracy tests were conducted We calculated population-level annual range by isolating sequences of locations from individuals with at least 270 days of data from 2018-2019. For each animal-year fitting that criteria, we calculated an individual level UD of annual use using Brownian Bridges. We then averaged the individual annual UDs to create a population-level UD of annual use and identified the core annual range using the 50% isopleth, and broader annual range with the 99% isopleth. 20200518 Vector G-polygon 53 Albers Conical Equal Area 29.5 45.5 -96.0 23.0 0.0 0.0 coordinate pair 0.6096 0.6096 meters North_American_Datum_1983 GRS_1980 6378137.0 298.257222101 PR_AZ_SouthInterstate40_AnnualRange_Ver1_2019.shp Attribute Table These data provide the location of annual ranges for pronghorn (Antilocapra americana) from the South of Interstate 40 herd in Arizona.
