The Douglas fir (Pseudotsuga menziesii) is a coniferous evergreen tree native to western North America. It is the most common conifer in the Pacific Northwest region of the United States and Canada, and is also found in the Rocky Mountains and Sierra Nevada.
The Douglas fir is a large tree, typically growing to heights of 50–100 m (160–330 ft), with a trunk diameter of 1–2 m (3.3–6.6 ft). The bark is thick and deeply fissured, and is reddish-brown in color. The leaves are arranged spirally on the branches, and are 1.5–3 cm (0.6–1.2 in) long, with a pointed tip. The cones are 5–10 cm (2–4 in) long, and are composed of thin, papery scales. The seeds are small, winged, and are dispersed by the wind.
The Douglas fir is a valuable timber tree, and its wood is used for a variety of purposes, including construction, furniture, and paper. The tree is also a popular ornamental tree, and is often planted in parks and gardens. The Douglas fir is an important part of the Pacific Northwest ecosystem, and provides habitat for a variety of wildlife, including birds, squirrels, and deer.
Douglas fir is native to North America but was brought to the UK
in 1827 by botanist David Douglas
and it can now be found in a variety of habitats, including open
forests with plenty of moss and rainy conditions. It thrives in
western areas of the UK, where rainfall is higher and can also
be found in other European countris.
