  1. Use clearcutting to increase understory diversity

    A replicated, randomized, controlled study in 1995-1999 in temperate mixed forest in Ontario, Canada (MacDonald, Cherry & Thompson 2004) found no effect of clearcutting on the size of trees and shrubs. There was no difference between treatments for: height of <4.0 m tall (71-140 cm), and DBH of >4 m tall and 1-10 cm DBH (5.7-6.2 cm) coniferous trees, height (59-177 cm) and density (5,417-12,292 stems/ha) of hardwood regenerations, and height (109-168 cm) and ground cover (33-51%) of shrubs. Data was collected in 1999 in four treatment plots (100 × 100 m): 0% (clearcut), 36%, 68%, and 100% (uncut) of basal area removed, established in 1995 in each of four blocks.
