The Growing Dynamic of Pure Scots Pine Stands Using Different Thinning Regimes in Lithuania

The aim of this study is to relate initial stand density and thinning intensity tree diameter, height, volume increment based on continuous 30-year observations in experimental stands Scots pine (Pinus sylvestris L.). experiments were established 1990 1992, the model each trial comprised five variants: control four plots with densities up 3.0–4.4, 2.0–2.4, 1.0–1.2, 0.5–0.6 thousand trees per hectare after thinning. Since establishment, only dead removed plots, other thinned according predefined treatment plans. Our shows that lowest diameter was found highest most intensive which 1.5 times higher. However, intensification signs growth stabilization cannot guarantee them position productivity cumulative future.
