    Summary of 2016 Bat Research Conducted at Roseau River WMA
    (University of Minnesota Duluth, 2016-12) Swingen, Morgan; Moen, Ronald; Baker, Richard
    Crews from the University of Minnesota – Natural Resources Research Institute mist-netted bats for four nights during July 2016 in Roseau River Wildlife Management Area as part of a statewide project on northern long-eared bat habitat use. We captured 6 bats of 3 species: hoary bat, eastern red bat, and little brown bat, but did not capture any northern long-eared bats. This was likely due to the lack of large blocks of contiguous forest at Roseau River WMA and in the surrounding landscape. Because no northern long-eared bats were captured, we did not do any further research at the WMA. This report details work done at Roseau River Wildlife Management Area as part of a statewide study of northern long-eared bat habitat use. A report summarizing the results of the statewide project will be available in early 2017.

    Summary of 2016 Northern Long-eared Bat Research in Minnesota
    (University of Minnesota Duluth, 2016-12) Swingen, Morgan; Baker, Richard; Catton, Timothy; Kirschbaum, Kari; Nordquist, Gerda; Dirks, Brian; Moen, Ronald
    Crews from the USDA – Forest Service, University of Minnesota - Natural Resources Research Institute, Minnesota Army National Guard (MNARNG), and Minnesota Department of Natural Resources captured 646 bats throughout the forested region of Minnesota from June 6 – July 21, 2016. Bats of 8 species were captured during mist-netting surveys, including the first evening bat (Nycticeius humeralis) confirmed in Minnesota. We captured 95 individuals of our target species, the northern long-eared bat, and attached transmitters to 45 adult females (39 reproductive, 6 non-reproductive or undetermined). These 45 bats were tracked to 111 unique roost trees of at least 20 species. Crews conducted emergence counts at roost trees and observed between 1-71 bats emerging. Roost trees varied in both DBH and height, as well as decay stage. The roosting patterns observed in 2016 were similar to those seen in 2015, where bats appear to be using a variety of available trees.

Roost trees varied in both DBH and height, as well as decay stage. The roosting patterns we observed at Beaver Creek Valley 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.

    Summary of Bat Research in Camp Ripley Training Center and Arden Hills Army Training Site, MN 2016
    (University of Minnesota Duluth, 2016-12) Dirks, Brian; Dietz, Nancy; Baker, Richard; Swingen, Morgan
    Crews from the Environmental Office at Camp Ripley Training Center (CRTC) captured 92 bats in CRTC from June 6th – 24th, and 99 bats at Arden Hills Army Training Site (AHATS) July 6th – 10th, 2016. Bats of seven species were captured during mist-netting surveys, including the first recorded capture of an evening bat (Nycticeius humeralis) in the state of Minnesota. We attached transmitters to 3 pregnant northern long-eared bats at CRTC and 3 lactating little brown bats at AHATS. Three northern long-eared bat roost trees were identified at CRTC. The little brown bats captured at AHATS were tracked to two roosts, both in buildings. Roost trees at CRTC varied in height and decay stage. The roosting patterns observed at CRTC 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 at CRTC and AHATS 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.
