Use clearcutting to increase understory diversity
A replicated, controlled study in 1995-2005 in boreal forest in Ontario, Canada (Man et al. 2008) found that clearcutting increased the density and height of conifer regenerations and decreased the density of hardwood regenerations. Conifer regeneration density (stems/ha) was higher in clearcut (8,000) than in partial-cut and uncut plots (2,000-3,000) Height was higher in clearcut and partial-cut plots (270-300 cm) than uncut plots (140 cm). Hardwood regeneration density was lower in clearcut (1,500) than partial-cut and uncut plots (4,500-5,000). Height was similar in all treatments (110-180 cm). Four plots (100 × 100 m): one uncut, two partial-cut and one clearcut (0%, 40% and 100% of merchantable trees basal-area removed) were replicated in four blocks in January-February 1995. Data were collected in 2005 in 12 subplots (2 × 2 m) within each plot.
