What is a beech tree?
A beech is any of about 10 species of deciduous trees of the genus Fagus in the family Fagaceae. Beech trees are native to temperate and subtropical regions of the Northern Hemisphere. They are tall, wide-spreading trees that typically live for 400 years or more.
The wood of beech trees is pale red-brown, durable underwater, and often used for tool handles and shipping containers. Beech trees produce beechnuts, which are sweet-flavored nuts enclosed in prickly burs that provide forage for game animals.
The American beech (Fagus grandifolia) and the European beech (F. sylvatica) are the most well-known species. Both can grow up to 30 meters (100 feet) tall and are economically important timber trees. Beech trees are susceptible to beech leaf disease, a novel and fatal plant disease.

Where do beech trees commonly grow?
Beech trees commonly grow in various regions across the globe. The American beech (Fagus grandifolia) is native to eastern North America, while the European beech (F. sylvatica) is distributed throughout England and Eurasia.
Other species include the Chinese beech (F. engleriana), which grows to about 20 metres (65 feet), and the Japanese blue beech (F. japonica), which grows up to 24 metres (79 feet). The Mexican beech, or haya (F. mexicana), can reach 40 metres (130 feet) tall, while the Oriental beech (F. orientalis) is a Eurasian tree that grows to about 30 metres (100 feet). Southern beeches are found in southern South America, Australia, New Zealand, New Caledonia, and the mountains of New Guinea. Beech trees grow best in sandy loam.

What do beech tree leaves and bark look like?
Beech trees are known for their height, rounded shape, and wide spread. Their bark is thin, smooth, and steel-gray.
The leaves of beech trees are toothed, parallel-veined, and shiny green, growing alternately along the stem. American beech leaves are blue-green, heavily veined, coarsely saw-toothed, narrow, and about 5 inches long, turning yellow in the fall. European beech leaves are slightly shorter, egg-shaped, and dark green, turning red-brown in autumn; in mild climates, they persist through the winter. Most tree species have bark that is unique in structure and appearance; in fact, many trees can be identified by the characteristics of their bark alone.

How does a beech tree reproduce?
Beech trees reproduce through seed propagation. They feature yellow-green male flowers hanging from threadlike stems and female flowers in pairs on short, hairy stems on the same tree. These female flowers develop into prickly burs, each enclosing one or two three-sided, sweet nuts.
Beech trees grow best in sandy loam and are slow-growing, potentially living for over 400 years. Their shallow, spreading root system often sends up suckers that can grow into thickets.

What animals or insects depend on beech trees?
Many animals and insects rely on beech trees for habitat and food. The nuts of beech trees serve as forage for game animals and are also used in fattening poultry. Bark beetles are among the insects that can be found on beech trees, where they bore into the tree to form an egg chamber. Additionally, the bess beetle lives under the bark of decaying logs. A South American edible fungus known as beech fungus also grows on beech trees.

How are beech trees important to forests and humans?
Beech trees, of the genus Fagus, are deciduous ornamental and timber trees found in temperate and subtropical regions of the Northern Hemisphere. The nuts of beech trees serve as food for game animals, poultry and can be processed into edible oil. The pale red-brown wood is valued for tool handles and shipping containers because of its durability underwater.
American beech (Fagus grandifolia) and European beech (F. sylvatica) are the most well-known species. They are economically important as timber trees and are often planted as ornamentals. However, both species are susceptible to beech leaf disease, a novel fatal plant disease likely spread by nematodes.

beech, (genus Fagus), genus of about 10 species of deciduous ornamental and timber trees in the family Fagaceae native to temperate and subtropical regions of the Northern Hemisphere. The pale red-brown wood is durable underwater and is valued for indoor use, tool handles, and shipping containers. The nuts provide forage for game animals, are used in fattening poultry, and yield an edible oil. For the related genus Nothofagus, see southern beech.
Physical description
Beech trees are tall, round-headed, and wide-spreading. The thin bark is smooth and steel-gray in colour. The toothed parallel-veined leaves are shiny green and are borne alternately along the stem. Yellow-green male flowers hang from threadlike stems. The female flowers, usually in pairs on short hairy stems on the same tree, develop into prickly burs enclosing one or two three-sided sweet-flavoured nuts. Beeches grow best in sandy loam. They are slow-growing but may live 400 years or more. Propagation is usually by seed; the shallow spreading root system often sends up suckers that may grow into thickets.
Major species
The American beech (Fagus grandifolia), native to eastern North America, and the European beech (F. sylvatica), distributed throughout England and Eurasia, are the most widely known species. Both are economically important timber trees and are often planted as ornamentals in Europe and North America; they may grow as tall as 30 metres (100 feet). The narrow, coarsely saw-toothed, heavily veined, blue-green leaves of the American beech are about 13 cm (5 inches) long and turn yellow in autumn. The slightly shorter, egg-shaped, dark green leaves of the European beech turn red-brown in autumn and, in mild climates, persist through the winter. Numerous varieties of the European beech are cultivated as ornamental and shade trees, such as the copper, or purple, beech, with copper-coloured foliage; the Dawyck beech, a narrow, spirelike, glossy-leaved tree; the fernleaf, or cut-leaved, beech, with narrow, deeply lobed, fernlike leaves; the oak-leaved beech, with deeply toothed, wavy-margined, oaklike leaves; and the weeping beech, with long pendulous branches and wide-spreading horizontal limbs. Both species are susceptible to beech leaf disease, a novel fatal plant disease likely spread by nematodes.

An Asian species, the Chinese beech (F. engleriana), about 20 metres (65 feet) tall, and the Japanese blue beech (F. japonica), up to 24 metres (79 feet) tall, divide at the base into several stems. The Japanese, or Siebold’s, beech (F. crenata) is grown as an ornamental in the Western Hemisphere. The Mexican beech, or haya (F. mexicana), a timber tree often 40 metres (130 feet) tall, has wedge-shaped leaves. The Oriental beech (F. orientalis), a pyramidal Eurasian tree about 30 metres (100 feet) tall, has a grayish white trunk and wavy-margined wedge-shaped leaves up to 15 cm (6 inches) long.
