Effects of acoustic deterrents on foraging bats

摘要: Significant bat mortality events associated with wind energy expansion, particularly in the Appalachians, have highlighted need for development of possible mitigation practices to reduce or prevent strike mortality. Other than increasing turbine cut-in speed, acoustic deterrents probably hold greatest promise reducing However, deterrent effectiveness and practicality has not been experimentally examined is limited site-specific case studies. Accordingly, we used a crossover experimental design prior control period show that activity was reduced 17.1 percent by deployment ultrasonic placed around gauged watershed weir ponds on Fernow Experimental Forest West Virginia. We caution while our results should be extrapolated scope typical production facility, warrant further research use fatalities.
