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