Distribution
Douglas Fir grows in the western provinces of Canada, West Coast states of the United States, as far south as western parts of Texas and Mexico. It prefers to grow in moist well drained soils and can be found growing in both pure stands and interposers in softwood forests. Douglas Fir can also be found growing on the rocky slopes of mountains.
General Description: The sapwood is very pale almost white in color. Trees that grow in rocky slopes tend to have narrower sapwood then those that grow in coastal areas. The heartwood is yellowish to a light reddish-brown and may have a orange hue. The growth rings in Douglas Fir are very pronounced, with the early wood being lighter in color then the darker redder heartwood. The grain is straight, but can have curly or wavy characteristics. The texture is variable depending on the width of the growth rings. Wood with narrow growth rings is more even in texture then wood with wide growth rings.
