Family: Pinaceae Common names: Fir, Noble fir, Oregon larch, Red fir, Western fir, White fir Distributed in: United States (North America) Distribution overview: Noble fir is native (in the U.S.) to the Cascade Mountains and high peaks of the Coast Range (3,000 to 5,000 feet) from western Washington through western Oregon to northwest California. It is usually found growing with other conifers in high mountain regions where short, cool growing seasons are common. It prefers moist soils and deep winter snows. Common uses: Beams, Boxes and crates, Building construction, Cabin construction, Casks, Concrete formwork, Construction, Decks, Decorative plywood, Dressed boards, Factory construction, Food containers, Form work, Foundation posts, Framing, Heavy construction, Joinery (external): ground contact, Joinery, Joists, Light construction, Lumber, Matches, Millwork, Moldings, Packing cases, Plywood, Porch columns, Pulp/Paper products, Pulpwood, Rough boards/dimension stock, Rough construction, Structural plywood, Utility plywood Environment profile: Widespread Tree size: Trunk diameter is 350-400 cm
