Potential economic returns to tree quality were analyzed for four uneven-aged cutting treatments and a control in a Wisconsin northern hardwood stand. The economics of tree quality changes were analyzed over a 20-year period (1971–1992), using a ma

The effects of six cutting methods on tree quality were observed for 20 years in a northern hardwood stand in Wisconsin. Cutting treatments included an uncut control, three levels of individual tree selection (heavy, medium, and light), crop tree rel

Forest ecologists have long believed that greater tree species diversity in hardwood forests reduces biological risk, but researchers have not yet linked diversification with economic returns for managed hardwood forests. This paper shows how managem
