Wildlife and Roads: A Resource to Help Mitigate Roads for Wildlife

An Internet-based interactive decision guide and resource center, Wildlife and Roads: A Resource to Help Mitigate Roads for Wildlife, was developed as part of National Cooperative Highway Research Program Project 25-27 and is now housed on the Center for Environmental Excellence by AASHTO website. 

The site provides a wealth of information, including links to the final NCHRP 25-27 report, as well as online access to related resources including a step-by-step decision guide for practitioners. The decision guide takes users through transportation project stages beginning with planning, through implementation, followed by adaptive management. The final report, Evaluation of the Use and Effectiveness of Wildlife Crossings, summarizes research on the use and effectiveness of wildlife crossings to mitigate habitat fragmentation and reduce wildlife vehicle collisions. The report provides guidelines for the selection, configuration, and location of wildlife crossing types and suggestions for the monitoring and evaluation of their effectiveness and maintenance.

Team members responsible for the project include:

  • John Bissonette, Ph.D, Utah State University
  • Patricia Cramer, Ph.D., Utah State University
  • Keith Knapp, Ph.D., P.E., University of Wisconsin
  • Bhagwant Persaud, Ph.D., M. Eng, Transportation Consultant, Ontario
  • Craig Lyon, M.S.Sc., P.Eng., Ryerson University
  • Ingrid Brakop, Insurance Corporation of British Columbia
  • Trevor Kinley M.E.Des, R.P.Bio and Nancy Newhouse, M.E.Des, R.P. Bio, Sylvan Consulting, British Columbia
  • Sandy Jacobson, MS, USDA Forest Service, Redwood Sciences Lab, California
  • Anthony Clevenger, PhD, Western Transportation Institute, Montana State University
