Mitigation crediting could provide a valuation approach that state DOTs could use to promote the construction of wildlife crossings and other enhancements to mitigate transportation project impacts. The two objectives of this research are to: • Collect and synthesize current information on valuation methods, metrics, criteria for credit development, and crediting mechanisms used by state DOTs and their partners for calculating and applying mitigation and advance mitigation credits for wildlife connectivity improvements. • Identify existing and potential quantitative methods and approaches for establishing the mitigation values of wildlife overpasses, underpasses, bridges, and culverts for habitat connectivity, and how that value is translated to mitigation credits.
