Influence of some soil characteristics on the productivity of stands in Dragomirna plateau, Suceava county, Romania

The interdependence between ecological factors of the forest site rock-soil has a largevariability in the case of Dragomirna plateau (because of the geology of the area) and occurs in varioussituations of site quality. As an consequence of this diversity, some of the soil properties represent alarger influence on the biometrical characteristics of the stands, implicitly on their productivity. Startingon the premise that not all the tree species present on the area have the same edaphic ecologicalexigences and the fact that the common beech, the main species in the analized tree stands is in asuboptimal climate (St nescu 1979), was considered to be useful to determine wich of the soil conditionsstudied, influence more the productivity of the main species from the Dragomirna plateau.
