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.

Odor
No specific smell or taste


Kiln Schedules
T8 - D3 (4/4); T6 - D1 (8/4) US
Schedule E - United States.


Drying Defects
Distortion
Special attention required
Severe shrinkage may result
Poor air circulation while slow drying may cause chemical sapwood stains
Moderate twist/warp
Moderate surface checking
Moderate end spitting

Use care to prevent splitting, checking, warping and other defects commonly associated with high shrinkage

Ease of Drying
Slowly
Fairly high risk of shrinkage
Dries fairly rapidly but requires care


Kiln Drying Rate
Naturally dries at a moderate speed


Tree Size
Tree height is 30-40 m
Bole length is 20-30 m
Trunk diameter is 100-150 cm


Product Sources
Lumber produced from Shagbark hickory is available on the market at medium to high prices.

Polishing

Staining
Satisfactory staining characteristics

Typical uses of species, such as for tool handles, do not require stains.

Strength Properties
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.
