Contrasted thinning strategies simulated in even-aged, two-layer and uneven-aged stands. Initial stands (bold solid lines) had a same volume (400 m3/ha) but different densities (N = 400, 520 and 1,050 trees/ha respectively). Results of the simulation of selection thinning (15% of total N), mechanical thinning (25% of total N) and low thinning (45% of total N) are presented through mean harvesting DBH distributions (normal solid lines) and 95% confidence intervals (dotted lines)
