    Comment: The nuts of all the hickories are important food for wildlife, especially squirrels. The wood is hard, heavy, and strong and is used for tool handles, ladders, and other specialty items. This and other hickories are used for barbecue and other smoked meats. Carya is the ancient Greek name for walnut; alba refers to the light-colored wood; tomentosa refers to the hairy leaves.
