About

Abies grandis (grand fir, giant fir, lowland white fir, great silver fir, western white fir, Vancouver fir, or Oregon fir) is a fir native to northwestern North America, occurring at altitudes of sea level to 1,700 metres (5,600 ft). It is a major constituent of the Grand Fir/Douglas Fir Ecoregion of the Cascade Range.

The tree typically grows to 40–70 m (130–230 ft) in height, and may be the tallest Abies species in the world. There are two varieties, the taller coast grand fir, found west of the Cascade Mountains, and the shorter interior grand fir, found east of the Cascades. It was first described in 1831 by David Douglas.

How to grow it

The boughs create a rain shelter for humans.

Native Americans used both grand fir and white fir, powdering the bark or pitch to treat tuberculosis or skin ailments; the Nlaka'pamux used the bark to cover lodges and make canoes, and branches were used as bedding. The inner bark of the grand fir was used by some Plateau Indian tribes for treating colds and fever.

Where it grows

The coastal variety of grand fir grows in temperate rainforest environments along the Pacific coast from southwest British Columbia to Northern California, with the inland variety growing in montane conifer forests of eastern Washington, the Idaho Panhandle, and far western Montana. It can be found growing at elevations of up to 1,700 m (5,600 ft). Habitats typically receive at least 640 mm (25 in) of annual rainfall, but are still too dry or outside the range of more shade-tolerant competitors like western hemlock and western redcedar. Along with the closely related white fir, grand fir is more shade tolerant than Douglas-fir.
