Bats of 2 species were captured during mist-netting surveys. We captured five individuals of our target species, the northern long-eared bat, and attached transmitters to four pregnant females. These four bats were tracked to 11 unique roost trees of 7 species. During emergence counts we counted from 1 to 28 bats emerging from these roost trees. Roost trees varied in both DBH and height, as well as decay stage. The roosting patterns we observed at Whitewater State Park and WMA were similar to roosting patterns we have observed in other areas of Minnesota, where bats appear to be using a variety of available trees. This report details work done in Whitewater State Park and WMA as part of a statewide study of northern long-eared bats. A report summarizing results of the statewide project will be available in early 2017.enMist-netting surveyRoosting patternsLittle brown batBig brown batNorthern long-eared batEastern red batSilver-haired batTricolored batHoary batNatural Resources Research InstituteUniversity of Minnesota DuluthTechnical Report
