Bats of 6 species were captured or observed during mist-netting surveys. We captured six individuals of our target species, the northern long-eared bat, and attached transmitters to four adult females. These four bats were tracked to 14 unique roost trees of 6 species over 13 days. During emergence counts we counted from 1 to 26 bats emerging these roost trees. Roost trees varied in both DBH and height, as well as decay stage. The roosting patterns we observed at Itasca State Park 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 Itasca State Park 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
