Shagbark hickory (Carya ovata)

Family: Juglandaceae

Common names: Hickory, Scalybark hickory, Shagbark hickory, Shellbark hickory

Distributed in: Canada, United States (North America)

Distribution overview: Shagbark hickory occurs throughout most of the eastern North America but is largely absent from the southeastern and Gulf coastal plains and the lower Mississippi Delta.It is found from southeastern Nebraska and southeastern Minnesota eastward through southern Ontario and Quebec to Maine and extends southward to Georgia, Alabama, Mississippi, Louisiana, and eastern Texas.Disjunct populations have been reported in the mountains of northeastern Mexico. Native to about the eastern 1/2 of the U. S. and isolated locations in the mountains of Mexico. Preferes well-drained floodplain forests and mesic upland forests.

Heavy
Compression strength (parallel to grain) = high
Bending strength (MOR) = high
Bending strength in the air-dry condition (about 12 percent moisture content) is very high. Maximum crushing strength, or compression parallel to grain in the air-dry condition, is also in the very high range. It is stronger than Hard maple, and very heavy. Various species in the genus Carya, including Shagbark (C. ovata ), Pignut (C. glabra ), Mockernut (C. tomentosa ), and Shellbark (C. laciniosa ) are often marketed together as hickory because of very close similarities. The density and other related properties of the species are determined significantly by the rate of growth. Wood with wide growth rings are generally high in density and strength.
