Thin trees within forests: effects on mature trees
A replicated, randomized, controlled study in 1976-2008 in boreal forest in Maine, USA (Weiskittel et al. 2011) found that thinning decreased tree density and basal area. Number of trees/acre was higher in unthinned (2,962) than row-thinned (2,279) and the lowest in tree-released (1,699) and combined treatments (1,716). Basal area (ft2/acre) was higher in unthinned (229) than tree-release (188) and combined treatments (173), and higher in row-thinned (206) than combined treatments (173). Data was collected in 2008 in four replicates of unthinned, row-thinned (5 ft. wide row removal with 3 ft. wide residual strips), tree-release (cutting selected trees at 8 ft. intervals) and combined (row-thinned plus tree-release) treatment plots (64 × 64 ft.) established in 1976.
