Thin trees within forests: effects on young trees Forest Conservation

A controlled study in 1997-2001 in temperate coniferous forest in Japan (Zhu et al. 2003) found no effect of thinning on Japanese black pine Pinus thunbergii seedlings density. Density (seedlings/m2) was similar in all thinning treatments (unthinned: 14; 20%: 16, 30%: 13; 50%: 17). Four treatments: unthinned and 20%, 30% and 50% of the area thinned in a patch pattern were applied each to a 40 × 50 m forest section in December 1997. Japanese black pine seedlings were monitored four growing seasons after thinning in five 2 × 2 m plots in each treatment.
