University of Minnesota M.S. thesis. April 2012. Major: Integrated biosciences. Advisor: Gerald J. Niemi. 1 computer file (PDF); vi, 36 pages.I compared the breeding bird communities of managed and unmanaged boreal forests in northeastern Minnesota. Birds were sampled in the spring and summer of 2010 and 2011 in the Superior National Forest (SNF, managed landscape) and Boundary Waters Canoe Area Wilderness (BWCAW, unmanaged landscape). Twelve point counts were completed along each of 10 paired transects for a total of 240 points, 120 points within each of the SNF and BWCAW. The total number of individuals detected per point was significantly higher within the BWCAW (F=9.76, p=0.01). Avian species richness per point was also significantly higher within the BWCAW (F=11.17, p
