Strategies to Reduce Burro-Vehicle Collisions in the Lake Pleasant Area

A large and growing population of wild burros lives in the vicinity of Lake Pleasant north of Phoenix, Arizona. Included in this region is the Lake Pleasant Herd Management Area (HMA). The burros are under the guardianship of the U.S. Bureau of Land Management (BLM), as established by the Wild Horse and Burro Act of 1971 (Public Law 92-195). Burros are widely distributed in the region and affect portions of the state highway system (Interstate 17, State Route 74, and State Loop 303) and roads under the jurisdiction of Maricopa County, Phoenix, and Peoria. Burros enter roadways for reasons that are presently unclear. A complete understanding of burro movements has not been established. No studies on burro movements relevant to roads or vehicular collisions have been conducted. The research team will: (1) document and analyze burro-vehicle collisions in the study area; (2) collect and document other relevant data, including ADOT’s fencing inventory; (3) identify and analyze burro movement, distribution, and road permeability in the Lake Pleasant HMA; (4) identify burros’ points of access to roadways and high-crossing locations; and (5) recommend data-driven strategies that ADOT can implement to restrict burros from the roadways and prevent collisions with vehicles.
