Wildlife-vehicle collision data collected by state departments of transportation and other agencies and organizations is currently not standardized, with different groups collecting different types of information with different spatial accuracy. As such, sharing and compiling data from different states or different sources is currently a difficult task, making comparisons between datasets nearly impossible and reducing the ability of researchers and decision-makers to prioritize actions to reduce conflicts between wildlife and transportation infrastructure. In order to better understand wildlife-vehicle conflict on federal public lands, the National Park Service and US Fish and Wildlife Service partnered with the Western Transportation Institute at Montana State University to develop a standardized data collection system for federal land management agencies to record where wildlife interact with roads and where they are being struck by vehicles. By recording both live and road-killed animals we can better understand how wildlife are moving along the road corridor and identify the highest risk areas for wildlife-vehicle collisions as well as areas that are important to maintain habitat connectivity and allow wildlife to safely access habitat on either side of the road. This system, called ROaDS (Roadkill Observation and Data System), utilizes ESRI’s Survey123 application to allow data collectors to record observations using their smartphones. This data is then immediately available in both a spreadsheet and a map with none of the extra work and issues that go along with manually entering data sheets from the field. After the ROaDS app was beta-tested by federal land management staff, the Western Transportation Institute partnered with the Center for Large Landscape Conservation to make the app available free of charge to other partners such as state agencies, tribal nations, and non-governmental organizations as part of a larger effort to standardize wildlife-vehicle collision data and improve spatial accuracy. By having a standard set of data fields being collected with the same spatial accuracy, data can be shared and analyzed across boundaries and jurisdictions regardless of where or by whom the data is collected. In addition to the standard data fields, the ROaDS form can be customized to meet the needs of any given geography including changing the species list and adding data fields for other research or monitoring needs. Currently, the ROaDS app is being used by federal land management agencies, two tribal nations, and multiple NGOs engaged in both systematic and opportunistic citizen science data collection efforts and provides critical information for decision-makers to most effectively develop solutions to make roads safer for people and wildlife.
