Human activities and development are increasingly influencing natural landscapes and pose a risk for negative human-wildlife interactions. National Parks, tasked with preserving natural resources and providing recreational opportunities, are often flashpoints of human-wildlife interactions. The availability of anthropogenic food (e.g., sandwiches, chips, candy) in National Parks prompt human-wildlife interactions by altering the behavior of wide-range of species. Raccoons (Procyon lotor) present a unique management challenge in Yosemite National Park (YNP) because of their ability to take advantage of anthropogenic food resources, capacity to serve as a reservoir for zoonotic diseases, impacts on native-species restoration, and influences on the foraging behavior of apex predators. The Yosemite Valley (YV) portion of YNP has a resident population of 1,035 people, hosts approximately 4.3 million visitors annually, and is the epicenter of human-raccoon interactions in YNP. To better understand how raccoons use anthropogenic food resources in YV, we placed GPS and VHF collars on 8 individuals and monitored their movements. We modeled the space use of raccoons as a first step in developing a management plan to reduce negative human-raccoon interactions.
