Climate and environmental impacts on beech and oak wood production in the Hyrcanian forests

Environmental and climatic conditions influence growth of the trees as well as beech (Fagus orientalis Lipsky), a species which is widely spread in the Hyrcanian forests in northern region of Iran. However, in the northern border of the forests, Oak (Quercus macranthera) dominates. Despite the vari...
