  14. Solutions or Best Practices for Reducing WVCs

  15. Wildlife Crossing with Fencing 87% average reduction in WVCs

  16. Wildlife Fencing Reported reductions in WVCs - 80-99% Wildlife fencing along US Hwy. 93 on Flathead Indian Reservation, MT

  17. VERMONT ARIZONA

  18. IN-vehicle Warning

  19. Reduce Speed by Traffic Calming, Reducing Design Speed 20 15 10 Roadkill per Mile 5 0 15 25 35 40 45 55 Posted Speed Roadkill by Posted Speed Limit in Yellowstone National Park Data Source: Gunther et al. 1998). Speed Bumps Used to Reduce WVCs in Australia

  20. Identification of Ineffective Measures or Practices

  21. Measures For Which Research or Construction Resources Should Not Be Used • Standard wildlife warning signs • Deer reflectors and mirrors • Audio signals in the right-of-way or deer whistles on vehicles • Olfactory repellants • Deer flagging models • Hazing • Intercept feeding • Wildlife relocation in order to reduce population size • Anti-fertility treatment in order to reduce population size • Seasonal road closures • Reflective collars placed on wildlife

  22. Future Actions • Incorporation of WVC reduction into the early stages of planning and design • Develop and implement guidelines and standards for collecting and reporting WVCs • Develop and implement guidelines for the evaluation of mitigation measures • Evaluate effectiveness of mitigation measures PDA-GPS prototype road kill data collector

  23. Make existing mitigation measures more effective Develop & apply population viability models to optimize location, type and dimensions of mitigation measures Establish national funding source for WVC reduction Technology transfer Future Actions Test site for 8 different roadside animal detection systems - Lewistown, MT
