The linear nature of surface transportation systems creates a suite of concerns for transportation and natural resource management agencies as they seek to ameliorate the impacts of their projects on environmental resources, as roads divide habitats and hydrological features. To help better understand the interactions between roads and environment the discipline of road ecology has emerged in the last 10 years. Road ecology strives to understand surface transportation infrastructure and its impacts on wildlife and motorist safety, aquatic resources, habitat connectivity, and many other environmental values. The effects of roads on wildlife populations have been the focus of many studies in the last decade and increasing concern for transportation and natural resource management agencies. Roads affect populations in numerous ways, from habitat loss and fragmentation, to barriers to animal movement, and wildlife mortality. The impact of roads on wildlife populations is a significant and growing problem worldwide. In rural and suburban areas of North America, accidents with wildlife are quickly becoming a major safety concern for motorists. / Supplementary Notes: Sponsored by Federal Highway Administration, Helena, MT.
