Title:  Archery hunting and scouting drives early fall migration and reduces high quality forage for elk with access to protected area refuge in southwest Wyoming
 
Abstract: Alteration of wide-ranging wildlife migrations can drastically impact the structure and function of ecosystems. However, the causes and consequences of shifting fall migration patterns remain largely unknown, despite the importance of nutrition during this time period for winter survival and reproduction. Here, we use 5 years of data from 73 female elk which utilize a landscape managed by 4 federal agencies, a state, and private landowners, to identify the driving factors behind the initiation of fall migration in two subpopulations, one of which migrates to a protected area where hunting is prohibited. Our results suggest that in areas where migratory ungulates span multiple jurisdictions, the benefits of migration may be dramatically impacted by unevenly distributed anthropogenic disturbance. As this is a common scenario globally, our work highlights the urgent need to improve our understanding of subtle changes in migratory behavior, both spatially and temporally, which may erode the resilience of migration to future change.
