Natural beech wood is a beech wood, that is able to replenish and sustain itself on its own. Beech is a valued timber, but most beech woods requires human intervention to replace old trees, since the young trees are not able to survive at all or at a rate, that sustains the beech population over time. There can be various reasons for this condition. Heavy forest floor coverage of other plants in the spring, shadowing the young beech-shoots is a common cause. Abundance of nutrient rich soils, will also be difficult to handle for beech woods in the long run. In a natural beech wood, one would see beech trees of all ages, including fallen and dead trees. Other tree types might be mixed in, but not to a degree that they threaten the dominant beech. The term could be used with other kinds of tree species, such as 'natural oak wood', 'natural birch wood', etc.. ==Natural beech wood forests== Examples of natural beech wood forests, includes: * Cwm Clydach National Nature Reserve in southeast Wales. * Marselisborg Forests in Denmark. * Serrahn Hills in North-east Germany. * The slopes of the Harz range in northern Germany. * Hainich National Park in central Germany. * Voděrady Beechwood in Czech Republic. * Stužica in Slovakia, one of Europes last primeval beech forests. * Carpathian Biosphere Reserve in southwestern Ukraine. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「natural beech wood」の詳細全文を読む スポンサード リンク
