Wildlife Management Projects
Bat Monitoring Summary
Carlton County Land Department (CCLD) 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).
American Bird Conservancy Mowing Project
The Land Department has partnered with the American Bird Conservancy (ABC) to create habitat for Golden Winged Warblers (GWWA). These birds have been identified by the Minnesota DNR as a species of greatest conservation need, largely because of huge declines on other parts of its breeding range. MPJ Enterprises mowed several sites in Wrenshall Township on County lands to manage for early successional habitat.
Target conditions included the thinning of the dense shrub understory. Trees greater than 5 inches diameter were left as reserve trees for warbler song perches. Tree and Shrub patches retained are approximately 30% of the original canopy cover. In addition to the GWWA, these project sites will provide important cover for nesting, brood rearing, and foraging. As wildlife moves in we will monitor for presence of GWWA and Woodcock.
Camera Trap Surveys
Through remote camera monitoring efforts the Land Department hopes to better understand how wild animals respond to forest and habitat management. Camera “traps” will be deployed for two survey periods; pre and post management event (timber harvest, mowing, etc.). Once images are collected and processed, species composition will be compared.
