Northern Long-Eared Bat

Bat Monitoring Summary

Carlton County Land Department contracted Western EcoSystems Technology, Inc. (WEST) to conduct acoustic and mist-net surveys for bats using two different pine plantation stands within Carlton County, Minnesota as summer habitat. The principle objective of summer bat surveys was to learn about bat activity and habitat, especially the federally threatened northern long-eared bat (Myotis septentrionalis; NLEB), within different pine plantation stands on Carlton County land. Surveys were conducted at two different times during the maternity season (May 15 to August 15; survey site 1: July 6 to 8; survey site 2: August 23 to 24, 2016). View the official report below.
