Solutions or Best Practices for Reducing WVCs
Wildlife Crossing with Fencing 87% average reduction in WVCs
Wildlife Fencing Reported reductions in WVCs - 80 -99% Wildlife fencing along US Hwy. 93 on Flathead Indian Reservation, MT

IN-vehicle Warning
Reduce Speed by Traffic Calming, Reducing Design Speed Roadkill per Mile 20 15 10 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
Identification of Ineffective Measures or Practices
• • • 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
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
Future Actions • 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 Test site for 8 different roadside animal detection systems - Lewistown, MT
