Ecology & Natural History

Habitat:

ILPIN Notes: Form - bare root, seedlings; readily adapts to a variety of soil conditions. Terrestrial furbearers (especially squirrels) eat seeds, flowers, bark, and twigs. This is an excellent den tree for squirrels and woodpeckers. Regarding small non-game bird food value, this pertains especially to evening grosbeaks. Leaves are usually cleft more than halfway to bases; silvery white below, and sharply toothed; staminate flowers in capitate clusters. Seed company numbers: 2, 4, 14, 15, 17, 19, 20, 23, 24, 25, 27, 28, 29, 31, 32, 35, 36, 37, 39, 40, 52. Brittle branches are easily damaged by storms. Sap can be used to make syrup, but yield is less than sugar maple.
