The David Douglas Fir is a large evergreen tree native to the western United States and Canada. It can grow up to 330 feet tall and has a straight trunk with thick, furrowed bark. The tree's needles are flat, dark green, and can be up to 1.5 inches long, providing a lush appearance. Named after the Scottish botanist David Douglas, who introduced it to Europe in the 19th century, this species is valued for its strong, durable wood. It thrives in moist, mountainous regions and is commonly used in construction, furniture, and paper products.
