The purpose of the database is to allow other universities, transportation professionals and interested individuals access to a complete reference source focused on animal-vehicle collisions and mitigation options. The interrelation between transportation systems, wildlife, and effective mitigation strategies are important in providing safe roadways for the traveling public. It is estimated there are 500,000 animal-vehicle accidents each year in the U.S. Over 120 fatalities and several thousand injuries per year can be attributed to animal-vehicle collisions in the U.S. Many innovative countermeasures are currently being tested and evaluated by state departments of transportation and other organizations. Even traditional countermeasures such as signing, fencing and animal crossings can vary greatly in effectiveness based on the methods being tested. Many agencies attempting to deal with this challenge do not have a good source of information regarding mitigation options and their effectiveness. Good efforts have been made to gather and consolidate this information this information including:· International Conference on Wildlife Ecology and Transportation (ICOWET), · Transportation Related Wildlife Mortality seminars,· Literature Availability Assessment for Relevant Interactions Between Highways Wildlife and fisheries in Montana, MDT MPART Project conducted by Lynn Irby MSU-Bozeman Department of Biology· Extensive bibliography developed by the Wenatchee Forestry Science Lab, and · “Critter Crossings” website developed by FHWMany scientific journals contribute to this subject including: Wildlife Society Bulletin, Journal of Wildlife Management, Journal of Mammalogy, Conservation Biology, Transportation Research Record, Journal of Environmental Management and Applied Animal Science and others. However, there is no current, comprehensive, user-friendly nationally recognized source of information concerning animal crash mitigation.
