Pseudotsuga menziesii
Douglas fir

Douglas fir (Pseudotsuga menziesii) is an extremely tall, fast-growing conifer. In optimal conditions, the tree grows over 100 m, with a trunk up to 4 m and lives more than 1300 years. It is native to western North America, from British Columbia in the north to Mexico in the south. The tree was brought to Europe in the 19th century, where it is now widespread in many European countries.

Douglas fir is one of the most important timber species in the world. In Europe, the tree is grown on plantations and used for reforestation, especially in France, Germany and the United Kingdom. As the tree produces strong, durable wood without knots and, given its fast growth rate and size, is a sufficient timber species. The tree is used for plywood, veneer, pulpwood, railway sleepers, wire poles and general construction. Furthermore, the tree is a popular ornamental, which is also the reason it was originally introduced to Europe.

Douglas fir is adaptable and able to grow under a wide variety of climatic conditions. While the tree prefers deep, moist, well-drained soils, it is able to grow in various types. The tree quickly colonizes areas after forest fires or other disturbances and tolerates shade; it also develops under canopies. In its natural habitat, the species grows in altitudes up to 3200 m.
