Abstract

Crews from the University of Minnesota - Natural Resources Research Institute captured 73 bats in St. Croix State Park from June 26th–30th, 2016. Bats of 5 species were captured during mist-netting surveys. We captured 13 individuals of our target species, the northern long-eared bat, and attached transmitters to six reproductive adult females. These six bats were tracked to 11 unique roost trees of at least 6 species. During emergence counts we counted from 1 to 27 bats emerging from these roost trees. Roost trees varied in both DBH and height, as well as decay stage. The roosting patterns observed at St. Croix 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 St. Croix 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.
