South of Interstate 40 elk reside primarily in Arizona’s Game Management Unit (GMU) 8. Upon completing population surveys in 2021, approximately 4,000 elk were estimated to inhabit GMU 8. Their summer range is primarily characterized by high-elevation ponderosa pine forests and grasslands. The elk radiate out from various origin points within their summer range to their winter range, comprised of rims of canyons in the area, including Sycamore Canyon, Tule Canyon, and Government Canyon. This series of canyons creates an impermeable southern boundary for this herd. Their winter range along the rim country is primarily characterized by pinyon-juniper, manzanita, and scrub oak. Interstate 40 is the primary threat to this herd’s migration corridor, limiting habitat connectivity and highway permeability between the South and North of Interstate 40 elk herds. Successful elk crossings of Interstate 40 are rare, and more than 65 elk-vehicle collisions occur along this stretch per year. To help mitigate this issue, an overpass is currently in the design phase, which will connect these two herds across Interstate 40. These mapping layers show the location of the migration corridors for elk (Cervus canadensis) in the South of Interstate 40 population in Arizona. They were developed from 71 migration sequences collected from a sample size of 25 animals comprising GPS locations collected every 2 hours.
