Predicting Wildlife Movement Associated with Road and Highway Systems

Wildlife-vehicle collisions are economic, safety, and ecological costs of transportation systems. Although understanding of the reasons that collisions occur is increasing, for most road and highway systems in California and elsewhere, the proximate causes and contributing environmental and other factors are unknown. Most contemporary research points to the importance of existing road and highway systems in reducing habitat quality and imperiling species. Currently, highway and other transportation projects are generally planned, funded and designed before considering the potential impacts to wildlife and sensitive biological resources. By identifying critical wildlife movement needs in relation to transportation systems, transportation and other planners will have improved abilities to predict and mitigate (avoid, minimize, or compensate for) wildlife impacts. The project proposes to study the occurrence and movement of small and medium-sized mammals across development and traffic gradients adjacent to I-80 as it bisects the Sierra Nevada. The project will investigate the effects of these gradients on spatial and temporal aspects of mammal movement and behavior. Data from these investigations will be immediately useful to transportation agency planners and biologists working in the area. Knowledge gained about wildlife movement in association with transportation system will be important for both mitigation investments and advancement of road ecology.
