Butternut (Juglans cinerea)
Family: Juglandaceae
Common names: Butternut, Nogal, Nogal blanco, Nogal silvestre, Nuez meca, Oilnut, Tocte, Tropical walnut, Walnut, White walnut
Distributed in: Canada, United States (North America)
Distribution overview: Butternut is distributed from southeastern New Brunswick throughout the New England States except for northern Maine and Cape Cod.Its range extends south to include northern New Jersey, western Maryland, Virginia, and Tennessee.Small isolated pockets occur in North Carolina, northwestern South Carolina, northern Georgia, northern Alabama, northern Mississippi, and Arkansas.Westward it is found in eastern Iowa and southeastern Minnesota.Disjunct populations occur in Wisconsin, Michigan, and northeast into Ontario and Quebec.Throughout most of its range, butternut is not a common tree and its frequency is declining.The ranges of butternut and black walnut overlap, but butternut occurs farther north than and not as far south as black walnut. Butternut grows best on streambank sites and on well-drained soils; it is seldom found on dry, compact, or infertile soils. It grows better than black walnut, however, on dry, rocky soils, especially those of limestone origin. Butternut is found most frequently in coves, on stream benches and terraces, on slopes, in the talus of rock ledges, and on other sites with good drainage, primarily on soils of the orders Alfisols and Entisols. It is found up to an elevation of 1500 in (4,900 ft) in the Virginias, at much higher altitudes than black walnut.
Common uses: Bedroom suites, Boat building, Boxes and crates, Building materials, Cabinetmaking, Canoes, Casks, Chairs, Chests, Concealed parts (Furniture), Desks, Dining-room furniture, Dowell pins, Dowells, Drawer sides, Excelsior, Fine furniture, Floor lamps, Furniture , Furniture components, Furniture squares or stock, Hatracks, Instrument cases, Interior construction, Interior trim, Joinery, Kitchen cabinets, Lifeboats, Living-room suites, Millwork, Moldings, Office furniture, Packing cases, Paneling , Radio - stereo - TV cabinets, Rustic furniture, Shipbuilding, Stools, Tables , Trimming, Woodenware
Product sources: Although some material from this species is available from environmentally responsible sources, supplies of butternut are rather limited and are getting even smaller. The tree is more valuable for its nuts than for its lumber.
