About

Quercus robur, pedunculate oak, European oak, or English oak, is a species of flowering plant in the beech and oak family, Fagaceae. It is a large tree, native to Europe and western Asia, and is widely cultivated in other temperate regions. It grows on soils of near neutral acidity in the lowlands and is notable for its value to natural ecosystems, supporting a diversity of herbivorous insects, acorn eating mammals and birds, and fungi.

The common name pedunculate oak refers to the acorns being borne on a peduncule, or stalk.

Where it grows

The species is native to most of Europe and western Asia, and is widely cultivated in other temperate regions.

Uses

Quercus robur is planted for forestry, and produces a long-lasting and durable heartwood, much in demand for interior and furniture work. The wood is identified by a close examination of a cross-section perpendicular to fibres. The wood is characterised by its distinct (often wide) dark and light brown growth rings. The earlywood displays a vast number of large vessels (around 0.5 mm in diameter). There are rays of thin (about 0.1 mm) yellow or light-brown lines running across the growth rings. The timber is around 720 kg per cubic meter in density.
