Аннотация: The static tree pulling method, strength and components of anchorage, structure and dynamics of root systems and the influence of stemreduction strategies on allocation of biomass and wind stability of Norway spruce (Picea abies (L.) Karst.) were analyzed. Concluding , that the wind stability is supported by implementing 'the lowest possible stem number in early years and the highest possible stem number in older age", a decreasing thinning intensity with increasing age (from D-Grade (very heavy thinning) to A-Grade (non-thinning) was proposed. The book describes the natural ecological basis for wind resistance of Conifers.
