Thin trees within forests: effects on mature trees
A replicated, controlled study in 1952-1995 in temperate coniferous forest in Maine, USA (Sendak, Brissette & Frank 2003) found that thinning decreased trees volume growth rate (final volume plus harvested volume plus mortality minus initial volume) but not their net growth (discounting mortality). Annual gross growth (m3/ha) was lower in thinned (2.51-4.27) than unthinned plots (4.08). Annual net growth was similar between treatments (unthinned: 1.59; thinned: 2.01-3.4). Two unthinned and 18 thinned (thinned in different time intervals following different procedures for 40 years since 1951) treatment units were established inside a 1,619 ha study area. Data was collected every five years from 1951, in a total of 307 plots (0.8 ha).
