(Cupressus nootkatensis or Chamaecyparis nootkatensis) aka Nootka Cypress, Yellow Cypress and Alaska Cypress. Alaska yellow-cedar is a coastal, high-elevation, tree species. Despite its name, it is actually a cypress. It is a medium-sized (rarely over 40 meters tall) evergreen. It is one of the slowest growing but most valuable conifers owing to the unique color, texture, and durability of its wood. Alaskan Yellow Cedar is a softwood that is distinctly different from other cedars in its yellow color, dimensional stability, extreme strength and hardness.
(Calocedrus decurrens) aka California White Cedar is native to the mountains of the far west. The natural range extends from near the Columbia River in Oregon south to northern Baja California in Mexico and east to western Nevada. The heartwood is a light to medium reddish brown, soft, light, fine grained, and pleasantly aromatic. The wood contains substances that retard decay and repel moths. The wood is traditionally used for cedar chests, siding, interior paneling, shingles, decking, pencils, and fence posts.
Western Red Cedar
(Thuja plicata) Western Red Cedar is a medium- to large-sized (rarely over 60 meters tall), evergreen, scale-leaved conifer. It is one of the most valuable conifers owing to the unique color, texture, and durability of its wood; it is also the provincial tree of B.C. The soft red-brown timber has a tight, straight grain and few knots. It is valued for its distinct appearance, aroma, and its high natural resistance to decay, being extensively used for outdoor construction in the form of posts, decking, shingles, and siding.
Douglas Fir is dimensionally stable and generally recognized for its superior strength-to-weight ratio. Its high specific gravity provides excellent nail and plate-holding ability. Consequently, it is typically used as framing lumber in structural applications and is also a superior material for covered exterior flooring, such as porches.
