Judith Gap Energy, LLC operates the Judith Gap Wind Energy Project (JGWEP) in Wheatland County, Montana. The Farm Service Agency and the Montana State Lands Department were cooperating agencies for the preparation of an environmental assessment for the project. One of the stipulations for the Finding of No Significant Impact was a commitment to monitor avian and bat fatalities during operations. The Avian and Bat Monitoring Plan, Judith Gap Wind Energy Project, Wheatland County, Montana (TRC 2006) presented a detailed protocol for monitoring bird and bat fatalities at the JGWEP. Studies were conducted during the fall 2006 and spring 2007 migration periods, and this report presents the results and fatality estimates for birds and bats at JGWEP. A grassland bird displacement study was also conducted, and comparisons were made between point counts of breeding grassland birds before and after construction and operations of the JGWEP.
