Carya ovata
Overview
The Shagbark Hickory is one of the most distinctive native hardwood trees in eastern North America. Known for its long, peeling strips of bark, nutrient-rich nuts, and exceptional wildlife value, it is a characteristic species of mature Appalachian forests. Its rugged appearance and unmistakable bark make it one of the easiest trees to recognize during any season.
Like other hickories, Shagbark Hickory is a long-lived tree that contributes to forest diversity, wildlife habitat, and the cultural history of the region. Its strong wood and edible nuts have made it valuable to both people and wildlife for centuries.

Native Range
Shagbark Hickory is native to eastern North America and occurs throughout West Virginia. It grows in rich upland forests, stream valleys, bottomlands, and woodland edges, often alongside oaks, maples, beeches, and other Appalachian hardwoods.
The species prefers deep, well-drained soils but adapts to a variety of site conditions across its range.
Ecology and Wildlife Value
Shagbark Hickory is one of the most valuable wildlife trees in eastern forests.
Its nuts provide food for:
- Squirrels
- Chipmunks
- White-tailed deer
- Black bears
- Wild turkeys
- Wood ducks
- Various small mammals
The loose bark also provides important habitat for wildlife. Several bat species, including the Indiana Bat and Northern Long-eared Bat, may use spaces beneath the peeling bark as summer roosting habitat.
The tree supports numerous native insects and contributes significantly to forest biodiversity.
Human Uses and Cultural Significance
Shagbark Hickory has long been valued for both its nuts and its exceptionally strong wood.
The wood is commonly used for:
- Tool handles
- Sporting equipment
- Furniture
- Flooring
- Cabinetry
- Firewood
Because of its strength and shock resistance, hickory wood has historically been one of the most important hardwoods for tools and equipment.
The nuts are edible and have been harvested for centuries for baking, cooking, and direct consumption.
Hickory wood is also widely used for smoking meats because of its distinctive aroma.
Shagbark Hickory at Marshall University
Shagbark Hickory contributes to the diversity of the Marshall University Arboretum and provides visitors with one of the easiest native trees to identify. Its shaggy bark creates year-round interest, while its nuts support wildlife throughout the campus landscape.
As a West Virginia native species, Shagbark Hickory helps illustrate the ecological richness of Appalachian hardwood forests and demonstrates the important relationships between trees, wildlife, and people.
