Table 3. Thinning and final cutting removals (m3 ha–1) by timber assortments using alternative rotation lengths of 55–85 years in the four different treatments without and with the simulated late thinning at the age of 60 years. * indicates significantly (p < 0.05) higher volume of saw logs (incl. grade A butt logs) in the plots of quality thinning compared with the other treatments using the same rotation period.
