    1. NCHRP 25-27 Update: Evaluation of the Use and Effectiveness of Wildlife Crossings in North America Patricia Cramer & John Bissonette USGS – Utah Coop Fish & Wildlife Research Unit, Utah State University

    3. To understand and communicate ways to *increase the permeability of the roaded landscape for wildlife *to reduce animal-vehicle collisions and overall road associated death of wildlife

    4. Decision Guide for Mitigating Roads for Wildlife

    5. Research Team of 9 Ecologists and Engineers P.I. John Bissonette, PhD Patricia Cramer, PhD Keith Knapp, PhD, PE Nancy Newhouse Bhagwant Persaud, PhD, M Eng Trevor Kinley Craig Lyon, MSSc, M Eng Anthony Clevenger, PhD Sandra Jacobson, MS

    6. Evaluation of the Use and Effectiveness of Wildlife Crossings

    7. Safety Modeling

    8. Crash and Carcass Magnitude and Pattern Comparison Summary data, GIS plots, and regression models indicate different magnitude AND pattern of problem. Choice of database critical to describing problem and selecting locations for countemeasure implementation. Recommendations related to the data collection and use of data provided. Combination of consistently collected data preferred. Paper in Compendium focused on this work.]Summary data, GIS plots, and regression models indicate different magnitude AND pattern of problem.

    9. Accuracy Modeling

    10. Wildlife Crossings

    11. Effectiveness of Crossings

    12. Number One Priority Incorporate wildlife mitigation needs early in the transportation planning process

    13. The 7 Major Steps to Creating Wildlife Passages Consideration – ecological & safety reasons Selection – the types of mitigation measures Configuration – dimensions, materials Placement – where on the landscape & road Monitoring and Evaluation Maintenance – upkeep in perpetuity Final Plan and Continued Care – it never ends

    15. Resources Available
