Abstract
Crews from the Minnesota Department of Natural Resources captured 86 bats in Forestville/Mystery
Cave State Park from June 7th–10th, 2016. Bats of 4 species were captured during mist-netting surveys.
We captured six individuals of our target species, the northern long-eared bat, and attached a transmitter
to one pregnant female. This bat was tracked to 5 unique roost trees of 3 species. During emergence
counts we counted from 1 to 16 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 Forestville/Mystery Cave 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 Forestville/Mystery Cave 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.
