Growth elements and stand structure of artifically established Norway spruce stand at 37 and 62 years of age on Dalechamps Oak Site at Goc

Growth elements and stand structure of an artificially established Norway spruce were presented at age 37 62-yr on the basis a single permanent sample plot their changes analyzed. The was with 4500 seedlings per hectare. At 37-yr plot, 2600 trees hectare recorded basal area 43.52 m2?ha?1 standing volume 319,97 m3?ha?1. 62-yr, 878 42.61 454,48 First selective thinning, conducted mean aspirant?s height 17.6 m (500 hectare) characterized as moderate (28.3% 23.5% thinned) thinning from below (qd = 0.88). Out remaining number (1823 hectare), in following period between 38-62-yr, 956 (52.4%) removed, mostly through sanitary cutting that can be 0.68). initially selected aspirants 37-yr, 220 elite due to effects self-thinning unfavorable exogenous factors well regime. is statically unstable slenderness coefficient increased compared condition 37-yr. Thus, it concluded risk for achieving productive meliorative potentials increased, primarily absence adequate maintenance 38 62-yr.
