Powerful and majestic, this tree that can grow to great heights and live for thousands of years has been harvested over the millennia for its nuts, chestnuts. Sometimes ignored as fruit trees not worth harvesting, chestnuts have been left to fall victims of parasites. Others cultivate the chestnut to make marrons glacés or chestnut cream.
Castanea sativa is part of the beech family like the beech and oak. It is named for its nut, the chestnut, which was a basic ingredient in many peoples' cuisine, but is less popular today. Its name comes from Sanskrit which suggests origins in the east in Asia Minor where chestnuts were the most popular nut. Both beech and oak nuts are edible, but preferred by animals. This fruit tree species was introduced to Cévennes by the Romans. Along with its initial rapid growth, the chestnut also regrows after cutting, allowing the forest to regenerate at a high rate.

Why does EcoTree plant chestnut trees?

EcoTree plants chestnuts for two main reasons. First, chestnuts are large-diameter trees that, over time, provide many nooks and crannies that can accommodate a range of wild fauna (insects, small mammals, cave birds or even bats). Secondly, chestnuts are less popular and over 20,000 hectares worth have been abandoned. EcoTree is committed to preserving and promoting them. Their wood is valuable and they provide part of that essential diversity our forests need. Many animals are fed by chestnuts.

Chestnut - Overview

Chestnut - Overview

The straight trunk of the chestnut (Castanea sativa) has grey-brown bark that cracks vertically with age.
Its deciduous leaves alternate. They measure about twenty centimetres in length, grow on stalks, and have rugged, pointed edges. In autumn, its foliage turns a pretty yellow colour, before quickly turning brown.
As with oak and beech, two trees from the same family, chestnut leaves remain on the tree for part of the winter.

This tree first blooms after about twenty years in summer with yellow, male catkins up to 10-15 centimetres and small female flowers at the base of the catkins .

Its nuts are formed within a husk that is covered in flexible thorns and encases two to three chestnuts. Chestnuts are edible and are a staple food for many rural populations, especially in winter. The French distinguish between chestnuts and marrons, of which the latter is easier to peel from its husk, making it more expensive.

Chestnut - Species requirements

Chestnuts prefer climatic zones between 400 and 800 meters above sea level. It is a hilly, Mediterranean species that doesn't do well in too calcareous, too compact, or too humid soils, but prefers acid-to-neutral terrain that's dry and cool.
This fast-growing tree needs partial to full sun, though saplings prefer shade. Chestnuts suffer in intense cold and prefer poor, acidic or sandy soil. Chestnuts need to be fully established to withstand very harsh winters.

Chestnut Wood

Chestnut wood is waterproof and pliable and is used to make stakes, flooring, barrels, particle board, pulp, and furniture.
Its natural resistance to parasites, wood-eating insects, natural wear and tear, and bad weather makes it a wood well suited for exterior construction such as cladding and roofing.
Among all wood, chestnut is one of the easiest to work with. Hard yet malleable, its wood provides variety and quality work.

Chestnut nuts are edible. They can be used to make flour or desserts made with chestnut cream. Chestnuts are rich in vitamins, fibre, carbohydrates, magnesium, and potassium, making them a rural food staple in many places.

Chestnut Tree Symbolism

The chestnut (Castenea sativa), from the Fagaceae family, was nicknamed the "acorn of Zeus" by the Greeks. For the Celts, the chestnut was considered the guardian of men and animals at the end of each year. Its bare, gnarled roots make it a symbol of virility.
