American Chestnut
Castanea dentata
Most chestnut species are tall trees, commonly with furrowed bark when mature. The toothed leaves are lance-shaped to somewhat oval. Most male flowers are borne in long upright catkins; female flowers are arranged singly or in clusters at the base of short male catkins. Anywhere from one to seven nuts are surrounded by a spiny bur, and splits upon reaching maturity. The seeds lose viability rapidly and typically germinate shortly after they fall to the ground in autumn.

American Elm
Ulmus americana
Elm leaves are doubly toothed and often lopsided at the base. The petal-less flowers appear before the leaves and are borne in clusters on jointed stems. The nutlike fruit, surrounded by a flat, sometimes hairy, winglike structure, is called a samara. The American Elm of eastern North America may grow about 80 to 100 feet tall. It has dark gray, ridged bark, and elliptical leaves.

Autumn Olive
Elaeagnus umbellata
Autumn olive is a deciduous shrub that can grow 20 feet tall and 30 feet wide. Its leaves are elliptically shaped and can be distinguished from other similar shrubs by the shimmery look of the silver scales found on its lower leaf surface. Autumn olive's bell-shaped flowers are cream or pale-yellow color and bloom in early spring. They bring on red berries dotted with silver scales, which has led the plant to also be known as silverberry.

Big Tooth Aspen
Populus grandidentata
Bigtooth Aspens have oval leaves that are simple and alternate, with a short-pointed tip, large, rounded, irregular teeth, and a rounded base. When they first open in the spring, they are covered by dense whitish hairs, so the trees are very easy to identify. Young Bigtooth Aspen trees have light, smooth bark, tan to yellowish or greenish-gray. The bark often has an orange cast. The bark of a mature Bigtooth Aspen is darker and furrowed, often showing an orangish inner bar. As the tree ages, the bark darkens further, and the furrows deepen.
Native to the Northern Hemisphere, they are known for the fluttering of leaves in the slightest breeze. All aspens display a smooth, gray-green bark, random branching, rich green leaves that turn brilliant yellow in fall, and catkins (male and female on separate trees) that appear before the leaves in spring. The trees can reach a height of 80 feet.

Black Alder
Alnus glutinosa
The European alder, sometimes known as black alder for its dark bark and cones, is widespread throughout North America. The scaly bark is grayish-brown in some species and almost white in others. The oval leaves are alternate, serrate, and often shallowly lobed; leaves are sticky on unfolding but glossy when mature, they fall without changing color. Male and female flowers are born in separate catkins on the same tree; they form during the summer and usually blossom the following spring before the leaves open.

Black Cherry
Prunus serotina
The leaves of the Black Cherry are oblong, with a long-pointed tip and a tapering base. The leaves, like the branches, are alternate: they emerge from the stem one at a time. The edges of each leaf are finely toothed, the tiny teeth curve inward. In the spring, the leaves have a pair of brightly colored stipules (outgrowths on either side of the leaf stalk). Black Cherry leaves are shiny and dark green on the upper surface, light green below. The emerging leaves of the Black Cherry are often reddish. In fall, the leaves turn yellow to orange, then to red late in the season.
Black Cherry bark is reddish-brown and smooth when young, with conspicuous, horizontal gray lines. The inner bark has a bitter almond smell. As the trees mature, the bark breaks into scales that are curled outward. If you break off one of the scales, you will find a bright orange-brown underbark. The bark of an older Black Cherry consists of layers of reddish-brown or black scales with upturned edges. The bark of a mature Black Cherry tree is said to resemble burnt corn flakes, providing a handy memory device: Black Cherry/Burnt Cornflakes.
Black cherry trees display rapid growth, up to 50 - 80' tall and 30' - 60' wide. The fruits are important for many birds such as wrens, mockingbirds, thrashers, waxwings, and woodpeckers, and small and large mammals. A total of 456 moth and butterfly species are supported by Black cherry trees.

Black Locust
Robinia pseudoacacia
Black Locust trees usually grow to between 40 to 100 feet high. These trees have a narrow crown that tends to become bushy as the tree ages. The leaves of the tree are usually dark bluish-green with a lighter underside.
Black locust trees need plenty of sunlight to grow and do not tolerate shade well. They are often thought of as weed trees because they frequently grow in areas that have been disturbed or cleared, where sunlight is plentiful between gaps in other congregations of trees. Black locusts frequently spread through underground shoots as well. Frequently the trees have spines when they are young, losing the spines as they mature.
The flowers appear in large dense clusters on the tree. The flowers are between 4 to 8 inches in length and are known for their powerful fragrance. While the flowers are normally white, some varieties of black locusts have purple or pink flowers. The flowers hang down from the branches of the tree and they often provide nectar for honeybees. In return, these honeybees pollinate the plant.
The bark is usually gray and black with a red or orange tinge to it. The bark has many ridges and grooves that frequently form diamond patterns along the trunk of the tree.

Black Oak
Quercus velutina
Black oak is a North American timber tree distributed throughout the eastern United States. It usually grows to about 80 feet tall and may grow to 135 ft. on rich soils; it is common on exposed slopes and ridges, as it cannot tolerate shade. The tree's blackish outer bark is ridged in irregular blocks; the orange-yellow inner bark is a source of tannin and quercitron, a yellow dye. The leaf buds are sharply pointed and covered with down. The leaves are usually seven-lobed. Acorns provide food for a variety of birds and mammals and cavities provide a den, nesting, and roosting sites for birds. A total of 534 moth and butterfly species are supported by oaks.

Chinkapin Oak
Quercus muehlenbergii
A medium to large size oak with 4"-6 1/2" glistening dark green leaves in summer turning yellow-orange to orangish-brown in fall. Produces 1" sweet acorns that mature in a single season. The acorns are at the top of the food preference list for many wildlife species. The bark is an ashy light gray that breaks into narrow, thin flakes. As this species matures, it becomes a magnificent specimen and a conversation piece. Grows 40'-50' high with a similar spread under landscaping conditions, becoming 70'-80' high in the wild. Does best in well-drained soil and adapts to many different soil types. Grow in full sun.
Chinkapin oak acorns are the preferred food for wild turkeys, grouse, white-tailed deer, black bears, chipmunks, squirrels, and hogs. Cattle will eat the leaves.
The chinkapin oak is also commonly referred to as yellow chestnut oak, rock oak, or yellow oak. Early pioneers used its straight wood to make thousands of miles of fences in the states of Ohio, Kentucky, and Indiana. Later on, the trees were used to fuel the steamships that ran from Pittsburgh to New Orleans. They were also used as railroad ties for the new railroads that crisscrossed the Midwest.

Chokecherry
Prunus virginiana
Chokecherry is a deciduous shrub or small tree native to North America. It is named for the astringent, acidic taste of its reddish cherries, which may be made into jelly and preserves. The stones and foliage are poisonous. Chokecherries often form dense thickets on moist soils and are frequently attacked and defoliated by eastern tent caterpillars. The plant grows to a height of 20 feet, producing hanging spikes of disagreeably scented white flowers. The slender brown twigs also have an unpleasant odor and a bitter taste. The bark is brown or gray, smooth on new growth but becoming scaly with age.

Common Hawthorne
Crataegus monogyna
The Common Hawthorn typically grows 10 to 20' in height. There is a main trunk that on average, at maturity, can reach between 15 and 20 cm (about 8") in diameter. Hawthorn bark is gray with shallow, longitudinal fissures with narrow ridges. In younger trees, the bark is smooth and gray, as seen on a branch of the hawthorn. As they age, the bark darkens into a shade of brown and develops fissures and ridges.
Hawthorns have thorny branches. The thorns are smaller branches that arise from a larger branch and are typically 1 to 3 cm long. These thorns tend to be sharp. This deciduous tree has alternate branching, in which the twigs (or thorns) are not directly opposite each other.
Leaves are stalked, broadly ovate, and pinnately lobed. The lobes are rounded, with entire margins but toothed at the tip; veins are fine-hairy. Its blade is dull on top, and bluish green beneath. Flowers measure about 0.4" across. It has 5 calyx-lobes, is broadly triangular, blunt, recurved, and fine-hairy. This white flower has 20 stamens and one carpel. Bloom time is typically in June. Flowers produce an egg-shaped, red drupe. The fruits are rounded, oblong, or pear-shaped, relatively small (the size of a large, cultivated blueberry), and depending on the species, they range from orange-yellow, scarlet, red, yellow, blue, or black.

Eastern Hemlock
Tsuga canadensis
Eastern Hemlock is an evergreen tree that flourishes in moist soil. This species is a slow-growing, long-lived tree that may take 250 to 300 years to reach maturity. This tree may reach diameters of four feet and ages of 400 years.
This tree is also known as the Canada Hemlock or Hemlock Spruce. It is a member of the pine family. The common name "hemlock" was reportedly given because the crushed foliage smells a little like that of the poisonous herb hemlock, which is native to Europe.
The Eastern Hemlock has a loose, irregular, feathery silhouette, with fine, lacy twigs whose tips tend to droop gracefully. The root system of this species is shallow, making the tree vulnerable to ground fires, drought, and wind.
This tree has short, flat, blunt, flexible needles, about ½ inch long. The needles are rounded at the tip, dark green above and pale silvery below. The needles have rows of tiny teeth on the margins and appear to grow in flat sprays on the lower limbs of trees. The needles are attached to the twig by tiny slender stalks. The light green cones gradually turn into brown cones (about ¾ inch long) and remain soft and flexible until the seeds are released in the fall. The drooping cones persist through winter.
As with many trees, the bark of Eastern Hemlocks changes as the tree matures. When the tree is young, the bark is gray-brown and relatively smooth. As the tree ages, the bark becomes cinnamon brown, with thick, ridges forming flat plates.

Pitch Pine
Pinus rigida
Pitch pine is a native tree seen throughout the Northeast United States and Eastern Canada. On average it reaches thirty to forty feet in height, but it can grow to almost a hundred feet in ideal conditions. Pitch pines can live to be over two hundred years old and tend to achieve their maximum height after ninety years.
The pitch pine tends to regenerate growth after damage (cutting or burning) and will sprout twisting branches that may curve in different directions. This tendency can create an unusual, somewhat "open" shape and makes the pitch pine a sought-after species for bonsai enthusiasts. It has a rich dark green color to its needles; new growth is yellowish-green and easily recognizable.
The tree produces small cones, about two inches long, that take two years to mature and grow in clusters of three to five. Unlike many pines, the cones on pitch pines tend to remain on the tree for several years, instead of falling. As pitch pines grow older, they tend to take on interesting shapes, as branches regenerate in response to wind or other weather damage.

Swamp Chestnut
Quercus Michauxii
The Swamp chestnut oak, also called basket or cow oak, is a handsome member of the white oak group known for its large, fuzzy, coarsely-toothed leaves and big acorns. It is a large, deciduous tree that averages 60' to 80' in height with a 2' to 3' diameter. In rare cases, it may grow as tall as 120' with a 7' diameter. In open areas, the crown is low and widely spreading, but the tree has a more compact form when growing in a forest.
The thick, light gray bark is irregularly furrowed with long, narrow scales and shaggy rectangular plates. The leaves are simple, alternately arranged, 4" to 9" long, and 2 ½" to 5" wide. They are obovate, broadest in the middle and above. The leaf base tapers and the leaf tip is rounded. The upper leaf surface is lustrous, dark green, and smooth while the underside is duller and fuzzy. Leaf margins are coarsely wavy-toothed. Leaves turn crimson in the fall.
The ovoid acorns are 1" to 1 ½" long and light to dull brown. The bowl-like cap covers 1/3 to ½ of the acorn and has distinct, wedge-shaped, triangular scales. Acorns mature in one season and may grow singularly or in clusters of two or three. White-tailed deer, turkey, squirrels, and hogs eat the acorns. Cows also eat these acorns, as the common name 'cow oak' suggests.

White Oak
Quercus alba
White oak has a short stocky trunk with massive horizontal limbs. The wide-spreading branches form an upright, broad-rounded crown. The bark is light ashy gray, scaly, or shallow furrowed, often broken into small, narrow, rectangular blocks and scales. The leaves are dark green to slightly blue-green in summer, brown and wine-red to orange-red in the fall. The fall foliage is showy. Oaks are wind-pollinated. Acorns are produced generally when the trees are between 50-100 years old. Open-grown trees may produce acorns are early as 20 years. The white oak grows to a height of 50–80' and a spread of 50–80' at maturity, having the ability to live for centuries.
White oaks feature alternating leaves that are 4–8" long with 3–4 rounded, finger-like lobes on each side and one at the tip. This tree produces long, yellowish-green catkins drooping in clusters in the spring. It yields acorns that are up to 1" long with a warty cap that covers about ¼ of the nut. The acorns are one of the best sources of food for wildlife and are gathered, hoarded, and eaten by birds, hoofed browsers, and rodents. Leaf buds also are eaten by several bird species, and all parts of the tree are a favorite food for deer.

Black Chokeberry
Aronia melanocarpa
Black Chokeberry is a dependable small to medium sized shrub with an upright, mounded habit and can reach a height of 3 to 6 feet. Small clusters of white flowers in spring are followed by shiny black fruit. The dark green foliage turns reddish-purple in the fall. This plant is native to North America. It is native to low woods, swamps, bogs, and other moist areas but occasionally to dry areas. The common name of chokeberry is a reference to the tart and bitter taste of the fruits which are edible but so astringent as to cause choking in most of those who try. Fruits are sometimes used to make tasty jams and jellies.

Eastern Redbud
Cercis canadensis
Eastern redbud is named for where it grows, in eastern North America, and the beautiful, reddish flower buds. Other names include Judas-tree. Eastern redbud’s native range is New Jersey to northern Florida, west to Missouri and Texas and northern Mexico. Eastern redbud is a small deciduous tree. Trees typically grow 20 feet in height with a similar spread and have ascending branches and a rounded shape. Eastern redbud leaves are 3 to 5 inches high and wide. Leaves begin reddish, turning green as they grow larger. Leaves are dark green in summer and then turn yellowish in autumn. The flowers are small and rose pink with a purplish tinge. Flowers develop before the leaves in spring, emerging in clusters along the branches. By mid-summer the flowers are replaced by bean-like seed pods that persist through the winter. Redbud flowers and young legumes are edible. The thin bark is gray and becomes scaly on older trees.
