Description of project

Aim of the project is to evaluate effects of shallowly and deeply rooting tree species on the nutrient balance in forest ecosystems, particularly at sites under the long-term acidification or endangered by drought. Seven triplets of pure E. beech stands, pure N. spruce stands and their mixtures, each plot of 1000 m2, were established in the broader extent of environmental conditions (altitude 480 – 1020 m a.s.l., yearly mean temperature 4°C – 7°C, annual precipitation 500 – 1200 mm) within the Czech Republic. At the plot dbh, height, crown projection and geographical position of individual trees was measured, the total biomass was counted and the dendrochronological analyse is provided. Soil sampling to depth of 80 cm, foliage, wood, bark and fine roots chemical analyses are made. The total stock of main nutrients in biomass of trees according to tree species will be estimated. Results will be evaluated according to share in mixture, nutrition demand regarding to possible recommendation to forest management. The project is connected to COST Action FP1206, European mixed forests. Integrating Scientific Knowledge in Sustainable Forest Management. (EuMIXFOR) and thus includes international cooperation e.g. In the European transect study in mixed stands of Scots pine and European beech (32 triplets across Europe) or organisation of the EuMIXFOR final conference “Integrating Scientific Knowledge in Mixed Forests” in Prague (5th – 7th October 2016).
