Comparison of the Biomass and Dendrometric Parameters of Norway Spruce with Its Different Representations in Young Stands at Lower Altitudes in the Czech Republic

In forestry, it is still common to plant the seedlings of and cultivate Norway spruce (Picea abies L. Karst) at lower altitudes; however, climatic change that has been occurring increases evaporative demands in these areas. As a result, evidently suffers from drought, withers loses its power grow, thus, influencing stem thickness tree-height growth, as well biomass production. Therefore, growth production young (5-, 15- 25-year-old) stands altitudes (i.e., 200 500 m a.s.l.) was surveyed, case study, across Training Forest Enterprise “Masaryk Forest” Křtiny. There, 48 with varied representation up 30%, 31%–60%, 61%–90% over 91%) were analyzed. each stand, 12 trees sampled all social status classes sub-dominant, co-dominant dominant) detail. Basic dendrometric parameters (such total tree height, height crown base diameter breast height) amount above-ground organ stem, branches needles) investigated. Based on trends found here climate predictions, we recommend be cultivated only zones an altitude ca 400 a.s.l., annual precipitation 700 mm average temperature 7 °C, percentage stand no more than 30%.
