Globally, wildlife-vehicle conflict (WVC) fragments wildlife populations (due to road/traffic-aversion), kills and injures individual animals, can cause wildlife population declines, may eventually contribute to local or total extinction of certain species, and can harm vehicles and drivers. Preventing WVC begins with recording locations of conflict, such as vehicle crashes, animal carcasses (roadkill), or animal behavior around roads, such as avoidance of roads or crossing-behavior. These data are ideally used to inform transportation policy and planning and to retrofit roadways and their structures to reduce WVC. We are collectively involved with or manage eight regional or national systems for reporting WVC in collaboration with volunteers and/or agency staff. In this review, we survey systems for recording WVC by volunteers and agency staff at different geographical scales, based on existing literature and our personal …
