Family: Pinaceae, Pine view all from this family

Description Large to very large tree with straight trunk and narrow, open, conical crown of horizontal branches.
Height: 100' (30 m).
Diameter: 3' (0.9 m), sometimes much larger.
Needles: evergreen; 5 in bundle, with sheath shedding first year; 2-4" (5-10 cm) long. Slightly stout; blue-green, with whitish lines on inner surfaces.
Bark: gray and thin, smooth, becoming furrowed into rectangular, scaly plates.
Cones: 5-9" (13-23 cm) long; narrowly cylindrical, yellow-brown, mostly long-stalked; opening and shedding at maturity; cone-scales thin, rounded, ending in small point, spreading widely; long-winged seeds.

Habitat Moist mountain soils; in mixed forests and occasionally in almost pure stands.

Range Northern Rocky Mountains from British Columbia southeast to NW. Montana; also along Pacific Coast south through the Sierra Nevada to central California; to 3500' (1067 m) in north; at 6000-9800' (1829-2987 m) in south.

Discussion An important timber tree, Western White Pine is also a leading match wood, because of its uniformly high grade without knots, twisted grain or discoloration. It is one of the world's largest pines; the champion near Medford, Oregon, is 239' (72.8 m) tall. White pine blister rust, caused by an introduced fungus (Cronartium ribicola), is a serious disease of this and other 5-needle white pines; a resistant strain is being developed.
