B-Tree (Austria)
B-Tree, planted in April 2013, represents the typical mixtures of a warm lowland forests of Austria. The effects of tree diversity on growth, water relations, rhizosphere diversity and C sequestration will be investigated.
Design
The full factorial design consists of monoculture plots and plots of 2 or 4 species. The planted 2-species mixtures will allow the comparison of blocks dominated by tree species associated with ectomycorrhizal fungi (Carpinus and Quercus) or arbuscular mycorrhizal fungi (Tilia and Acer). Each monoculture or species mixture is replicated 4 times. The trees are planted in a hexagonal design with 1 m distance between each tree, which will allow thinning after canopy closure.
