Western red cedar (Thuja plicata) is a coniferous species from northwestern North America introduced to Europe in the second half of the 19th century. It is often associated with Douglas fir in the lush forests of the North Pacific coast or along streams and swamps.
The Amerindians used its soft, light, resistant and rotproof wood to build totems, houses and canoes. Today, cedar is cultivated as an ornamental tree, mainly for hedging and less commonly used during reforestation.
