2 American Chestnut Castanea dentata ALTERNATE branching pattern. Leaves are SIMPLE, ELLIPTICAL, & TOOTHED with bristle tips. SEED is large and brown with a spiny, sharp husk. 2-3 shiny nuts are found inside the husk. Nuts ripen in the fall. Flowers are called CATKINS and appear in spring and summer. Suffers from the Chestnut Blight which is a fungal disease affecting the bark. Most American Chestnuts found today are small stump sprouts, but before the blight began in 1904, American Chestnuts reached 100 feet tall. American Chestnut leaves are smooth and hairless on both sides, while Chinese Chestnut (planted for it s disease resistance) is fuzzy beneath. LEAF AND FLOWER Upland forest. Chestnuts were once so numerous along the eastern forests of the U.S. that it is said a squirrel could jump from chestnut tree to chestnut tree all the way from Georgia to New York without ever touching the ground. US Fish and Wildlife Service The nuts are eaten by deer, black bear, raccoon, rabbit, squirrel, chipmunk, turkey, grouse, and quail. Leaves are food for over 125 types of caterpillars and many other insects. SEEDS During colonization of North America, Chestnut wood was used for railroad ties, houses, barns, fences, and fuel. Its wood is still valuable and used for fence posts, fine furniture, musical instruments, and wood paneling. Tannic acid from the wood is used to tan leather. Chestnuts are called the bread tree because their nuts can be milled into flour. Chestnuts can be roasted, boiled, dried, or candied. Native Americans relied on the American chestnut as a dietary staple.

3 Autumn Olive Elaeagnus umbellata ALTERNATE branching pattern. SIMPLE leaves are ELLIPTICAL shaped with ENTIRE margins. Medium to large deciduous SHRUB. Underside of leaves are SILVERY- WHITE.

Twigs and leaves are eaten by white-tailed deer, elk, cottontail rabbits, and moose! Many mammals eat the acorns of red oak including the white-footed mouse and flying squirrel. Birds like the northern bobwhite and red-headed woodpecker eat the acorns. Many species of ducks also eat the acorns including the golden-eye duck. Many red oak trees hold onto their brown leaves in the winter, making them good shelter for a variety of animals. CATKINS Red oaks can be planted in polluted areas such as old coal mine spoils to restore a natural habitat. Traditionally acorns of many oak trees were used by Native American peoples as a food and medicine source. Red Oak acorns were soaked and boiled to remove bitter tannins.

5 Cecropia moths lay eggs on sassafras leaves. Sassafras Sassafras albidum ALTERNATE branching pattern. SIMPLE leaves are OVAL shaped.
