Shagbark Hickory
Long bark strips lift away from an old trunk, creating both the tree’s name and summer roost crevices for bats.

Most leaves carry five leaflets, with the terminal three largest. Sweet nuts feed wildlife and people, though hard shells demand effort; young trunks remain smooth enough that crown, buds, and leaves may be more useful than bark.
Collect nuts only with permission and never confuse a planted ornamental hickory with evidence of a natural woodland population. Give Shagbark Hickory room to remain undisturbed. Photograph mature hickory with long loose bark plates, five leaflets, and thick-husked nuts with its surroundings, and leave nests, dens, host plants, bark, and flowers as found. Best spring–autumn; nuts in fall.

Good to know
Young shagbark hickories can have smooth trunks, so five-leaflet foliage, buds, nuts, and crown form may identify them before the famous peeling bark develops.
