Distributed in: Canada, United States (North America)

Distribution overview: The species is distributed across North America from close to the northern limits of Alaska and British Columbia, east to Labrador, south to Maine, and west to Minnesota. It is also reported to occur in localized regions in northwestern Montana, South Dakota and Wyoming. White spruce thrives on various soil types, and is mostly found in coniferous forests, but sometimes in pure stands. It grows from sea level to near timberline at altitudes of 2000 to 5000 feet (610 to 1524 m). White spruce is also cultivated in Great Britain.

Common uses: Agricultural implements, Boat building (general), Boxes and crates, Building materials, Cabinetmaking, Canoes, Casing, Casks, Chairs, Chests, Concealed parts (Furniture), Concrete formwork, Cooperages, Desks, Dining-room furniture, Dowell pins, Dowells, Drawer sides, Fine furniture, Floor lamps, Food containers, Furniture , Furniture components, Furniture squares or stock, Furniture, Hardboards, Hatracks, Heavy construction, Insulating boards, Interior construction, Interior trim, Joinery, Kitchen cabinets, Ladders , Ladders, Light construction, Living-room suites, Millwork, Mine timbers, Moldings, Musical instruments, Musical instruments: piano, Musical instruments: strings, Oars, Office furniture, Packing cases, Pallets, Paneling , Particleboard, Plywood, Poles, Pulp/Paper products, Pulpwood, Radio - stereo - TV cabinets, Rafters, Roofing, Rustic furniture, Tables, Vehicle parts, Veneer

Product sources: Timber produced by White spruce, Black spruce (P. mariana), and Red spruce (P. rubens) are often mixed and marketed together under the trade name Eastern spruce since they are too similar to separate on the basis of structure.

Environment profile: Status within its natural growth range has not been officially assessed

Tree size: Tree height is 20-30 m The tree is reported to reach a height of 40 to 100 feet (12 to 30 m), with a trunk diameter of 12 to 24 inches (30 to 60 cm).

Colors: the heart isYellow, Yellow to golden-yellow to orangeand the sapwoodWhite to yellow, Yellow.The grain isWeak figure, the textureMediumand the lusterSlightly lustrous

Natural durability: Resistant to attack from powder post (Lyctid & Bostrychid) beetles, Should not be used under high decay hazard conditions without proper protection
