The two can be distinguished with certainty only in November. Pignut seed, averaging 440/kg (200/lb), is lighter than the seed of other hickory species. ; Sarg. The bark is tight rather than shaggy and fall color is golden. Control consists of felling infested trees and destroying the bark during winter months or storing infested logs in ponds. White-tailed deer occasionally browse hickory leaves, twigs, and nuts. Hickories exhibit embryo dormancy which is overcome naturally by overwintering in the duff and litter or artificially by stratification in a moist medium at 1° to 4 °C (33° to 40 °F) for 30 to 150 days.

Shagbark hickory tree has a light gray bark that peels as thick vertical plates; with a length of more than a foot, and both ends curling outwards. In forest tree nurseries unstratified hickory nuts are sown in the fall and stratified nuts are sown in the spring. Sprouts that originate at or below ground level and from small stumps are less likely to develop heartwood decay. The nuts are relished by several species of squirrel and represent an estimated 10 to 25 percent of their diet. About two-thirds of the species range is dominated by Ultisols, which are low in bases and have subsurface horizons of clay accumulation. Pignut hickory begins to bear seed in quantity in 30 years, with optimum production between 75 and 200 years (16). C.Â ovalis (Wangenh.) The maximum age for seed production is about 300 years.
