The beech, found only in northern temperate forests, is related to the oak and chestnut. Most species of beech are
deciduous, that is, they lose their leaves seasonally, although some are evergreens and keep their leaves. Both the
fruit and wood of the beech tree are useful; the fruit, called the beechnut, has a high oil content and is used as a pig
feed, while the wood is used in the manufacture of furniture.
