Utilization of Transportation Structures by Bats in Wyoming: A comprehensive investigation

The purpose of this study is to collect bat use data on bridges to aid Wyoming Department of Transportation (WYDOT) and agency partners in determining what bridge types are attractive to bats and to develop means of mitigation to minimize impacts to bridge maintenance and reconstruction timelines. Data collected during this study will be used to identify bridges and bridge types utilized by bats across Wyoming. This will provide highway engineers and wildlife managers with the information necessary to conduct bridge maintenance and reconstruction activities that minimize disturbance to bats as well as minimize the need to alter construction schedules. The study will also provide valuable information on the contribution bridge structure, provide to maternity roosts for bats and general use by bats of bridges. Finally, this study will enable researchers to work closely with WYDOT engineers to identify and test mitigation measures that can be used to minimize take (i.e., acoustic deterrents, netting, eviction devices).
