Best Methods Identifying Tree Species
Leaves: The shape of leaves is typically the top tree identifier and more reliable than the color or size of the leaves. The edges of the leaves—whether serrated or smooth—provide another solid clue or how the leaves are attached to the stems (alternate) along the branch or (paired opposite) making the shape of a plus sign along the stem.
- Opposites: maple and ash
- Alternates: oak, hickory, yellow poplar, birch, beech, elm, cherry, and sycamore (a type of maple).
- Whorled (less common) three or more leaves attach at each point or node on the stem, typically pines.
Bark: Usually, this is the second-best method to identify trees and about the only method during winter months. When observing bark, experts rely on a combination of texture, pattern, and color to identify trees. This can be tricky and sometimes frustrating to the novice observer because the bark of many species look very similar while others have undeniably defining features.
Size and Form: This can be tricky when trees are crowded in forest stands and forced to reach for the light. If the tree is allowed to grow in an open field or yard, it will be easier to identify, and size of the tree varies with age.
Fruits and Buds: Yet another way to cross-reference when a particular tree’s identity is in question. The only problem with this method is that the appearance of buds and/or fruit can be short-lived, and certain trees don’t produce fruit every year. Also, many trees don’t develop fruit (such as nuts and acorns) until the tree has reached a certain age of maturity, sometimes up to 25 years.
Flower: This is another way to cross-reference a tree’s identity, but again, the flowering season is short-lived.

1. Sugar Maple Tree (Acer saccharum)
Leaves
- Shape: 5 main lobes with pointed tips and U-shaped broad sinuses where the lobes meet; rarely 3-lobed; Classic Canadian maple leaf shape.
- Edges: Typically smooth or may have a few coarse, pointed teeth on the lobe margins.
- Other: Measures 3-6 inches long and wide; somewhat thin leaf; medium to dark green with matte surface.
Sugar Maple Tree Form and Sugar Maple Tree USDA Distribution Map
Sugar Maple Tree Size and Form: Large tree reaching up to 100 feet (30 m) and 50 feet (15 m) or more in width. Open-grown trees form stout, upright branches near the ground; in forest stands, the trunk is relatively straight and free of branches for many feet off the ground, with a broad, round-topped crown.
Sugar Maple tree leaves autumn colors typically are yellow, orange or red, but can be more varied and always beautiful. The photo below diplays leaves that dropped from the same Sugar Maple tree to the ground where I was lucky to pick them up.
Sugar Maple tree bark textures are quite variable as the tree grows showing deeper furrows with age. The oldest trees exhibit flake-like plates that are difficult to peel off, while younger trees possess fairly smooth bark. The colors of the bark can also vary, appearing greenish-gray to gray when younger, and more silver-gray in older trees.
Additional Sugar Maple Tree Info
- Sugar Maples are the most dominant species in Michigan as well as in many other eastern states, partly because they are shade tolerant.
- Michigan is the number-one U.S. producer of maple syrup derived from the sap of the Sugar Maple.
- Long-lived Sugar Maple trees typically live 300-400 years in ideal forest conditions with exceptions living up to 500 years. Growth in urban environments lifespan is often much shorter, ranging from 75 to 100 years due to environmental stressors like salt and pollution.
Red Maple Tree Leaf and Distribution Map (USDA Plant Database)
2. Red Maple Tree (Acer rubrum)
Leaves
- Shape: 3 to 5 lobes with shallow, sharply V-shaped sinuses angled where the lobes meet.
- Edges: Double-serrated and finely toothed.
- Other: Measures 2-5 inches long; faily thin leaf; dark green, paler underside, matte surface.
Red Maple Tree Size and Form – Medium to large tree growing up to 90 feet (27 m) high and 50 feet (15 m) or more wide. The trunk is often free of branches for half its length in forest stands. Upright branches form a low, dense, oval or rounded crown.
Red Maple Tree leaves autumn colors can vary from yellow to orange to more often deep red.
Red Maple Tree spring flower – You would have thought that the Red Maple was named for the often seasonal red leaf color, but instead, it was named for the flower color. As spring unfolds, the deep red blooms of the Red Maple cover the tree, then drop to the ground, sprinkling city streets and lawns with red.
The seed fruit (helicopter) of the Red Maple tree displays a characteristic horseshoe shape identical to other maple tree varieties, including Sugar Maples and Silver Maples. If you spot a tree with helicopters shaped more like clothes hangers, you probably have come across the invasive burgundy-colored Norway Maple tree, which has overtaken many areas where Sugar Maples once thrived. Note: The Red maple is the only native maple tree to seed in late summer and fall; all others seed during spring.
The Red Maple tree bark when young is fairly smooth with a greenish-gray to gray color and as the tree grows the bark becomes rougher with long vertical scales and more silver gray in color.
Additional Red Maple Tree Information
- Red maple leaves, especially when dried or wilted, are extremely toxic to horses, with 1.5 lbs of leaves being potentially fatal.
- One of the earliest trees to bloom in spring, providing vital nectar and pollen to bees, including honey bees and queen bumble bees.
- Early settlers used the bark to make ink and dyes (cinnamon, brown, and black). Native Americans used it as an analgesic and for treating coughs.
- A fast growing tree with typical lifespan of 80-100 years, exceptions can live up to 200 years in ideal conditions.
Northern Red Oak Tree Leaves
3. Northern Red Oak Tree (Quercus rubra)
Leaves
- Shape: 7 to 11 lobes showing tiny bristles at the very tips. Sinus gaps between lobes extend roughly halfway to the center vein (midrib), deeper compared to the Black Oak tree.
- Edges: Smooth
- Other: Large leaf, longer than wide measuring 5-9 inches long; firm leaf, dark green, paler underside with occasional hair tufts, slight shiny surface.
Northern Red Oak Tree Source and USDA Distribution Map
Red Oak Tree Size and Form: Large tree growing up to 100 feet (30 m) high and up to 70 feet (21 cm) wide. They form a broad, rounded crown of a few large and wide-spreading limbs and slender branches with dense foliage; dead branches are usually not persistent on the lower trunk.
Northern Red Oak autumn colors on young saplings can be quite red, whereas the older tree leaves turn from reddish brown to brown, remaining on the tree longer than most species through the winter months.
The Northern Red Oak acron is large compared to the Black Oak acorns. The cap covers 1/4 to 1/3 of the nut, has a matte finish, and is tan-colored. The cap has tight overlapping shingles. Trees between 25-50 years of age produce acorns.
Northern Red Oak tree bark is fairly smooth with shallow vertical cracks or fissures showing reddish bark underneath, often with some horizontal cracks; as the tree ages, the furrows deepen into long, broad, flat, and smooth-topped ridges (as if ironed out). The overall bark has a greenish-gray to gray tone in young trees that changes to grayish-brown and darker with age.
Additional Northern Red Oak Info
- With its dense leaf coverage and height, the Northern Red Oak is among the best shade trees to have on your property, offering a cool spot on scorching afternoons.
- Common names include Red Oak, Common Red Oak, Eastern Red Oak, Mountain Red Oak, Gray Oak.
- Northern Red Oak is the most common species of oak in the Northeastern U.S. The red oak group as a whole is more abundant today than it was when the European settlement of North America began, as forest clearing and exploitation for lumber greatly reduced the population of the formerly dominant White Oaks.
- Fast-growing, Norther Red Oak trees may live up to 400 years.
4. American Beech Tree (Fagus grandifolia)
Leaves
- Shape: Oval, pointed tip, slightly uneven parallel at lower stem attachment.
- Edges: Smooth, sharply toothed, deep well-defined veins ending at each incurved tooth.
- Other: Measures 3-6 inches long; medium thin waxy leaf; medium green at first to dark green, shiny sheen surface.
American Beech Size and Form The American Beech is a large tree, 115 feet (35 m) high up to 60 feet (18 m) wide. In the forest it’s a tall and slender tree with short branches forming a narrow crown; in the open, it has a short, thick trunk and numerous slender, crooked, spreading branches, forming a broad, compact, rounded crown. The trunk typically is straight, but sometimes can be crooked.
American Beech leaves turn yellow during the fall season and later deepen to a golden brown. The leaves cling to their branches throughout the winter months longer than all other broadleaf trees with the exception of the Red Oak.
- The American Beech tree bark is the quintessential defining feature of this tree, with its thin, smooth texture and light gray to greenish-gray color.
- The smoothness of the bark presents a tempting surface for carving initials and names, but besides marring its natural beauty, doing so is an invitation for fungi and wood-loving insect damage.
Additional Beech Tree Information
- Beech trees are a vital food source for wildlife, particularly bears, turkeys, and squirrels and is a favorite nesting tree for chickadee birds.
- The small, triangular nuts are edible and, in 19th-century England, were used to make oil for cooking and lamps.
- A long-lived, shade-tolerant giant can live from 300-400 years
5. Quaking Aspen Tree (Populus tremuloides)
Leaves
- Shape: Heart-shaped with a pointed tip; very similar to the Cottonwood leaves, but smaller and more rounded.
- Edges: Finely shallower toothed compared to Cottonwood tree
- Other: Measures 1 -3 inches long and wide; thin leaf; deeper green upper surface than underside; shiny upper surface. Features flattened stems that cause them to flutter in the wind.
Trembling Aspen Tree Form and Distribution Map
Quaking Aspen Tree Size and Form – Medium tree up to 60 feet (18 m) high and 30 feet (9 m) wide. The trunk can be straight or crooked, supporting an open, narrow to semi-rounded pyramidal crown of slender branches; display a slender trunk with little taper; smooth and branchless for much of its length.
Quaking Aspen’s autumn leaves turn yellow to greenish yellow or golden brown.
Quaking Aspen tree bark is smooth and whitish gray; typical straight trunk, but can develop split trunk, slender tree characterized by a narrow, pyramidal shape when young that matures into an open, rounded crown; sometimes mistaken for Cottonwood or Birch.
Additional Quaking Aspen Info
- Quaking Aspen derives its name due to the leaf stem being flat and structured at an angle, making them tremble, shimmer and quake at the slightest of breeze. I love the sound they make as well. This phenomenon is also true for their cousin species, the Cottonwood.
- The Quaking Aspen is another fast-growing species in the poplar family native to the cooler regions of North America and one of several species referred to by the common name “Aspen”.
- Typically lives for 50-150 years with those in the western U.S. often living longer than those in the East.
6. Eastern Cottonwood “Poplar” Tree (Populus deltoides)
Leaves
- Shape: Heart or triangular with a pointed tip.
- Edges: Well defined, deeply toothed, conspicuously incurved
- Other: Measures 3-5 inches long and wide; thick firm waxy leaf, dark green above, paler underside; shiny surface. Features flattened stems that cause them to flutter in the wind
Eastern Cottonwood Leaves and Distribution Map (USDA Plant Database)
Eastern Cottonwood Tree Size and Form – Fast growing, large tree up to 100 feet (30 m) high and up to 75 feet (23 m) wide. Within stands, trees develop slender, smooth trunks and relatively short, open, symmetrical crowns; trunks of open-grown trees often divide into two or more stems that form a wide-spreading, open and often irregular crown of massive branches.
Mature Cottonwood Trees (Free Standing)
The Eastern Cottonwood or Poplar tree autumn colored leaves typically turn golden brown to deep golden-yellow.
The Eastern Cottonwood (Populus deltoides) is dioecious, meaning individual trees are strictly either male or female. The sticky seed-containing female catkins dangle from branches during the spring season in colors of greenish to gold which later develop and open up to the fluffy seedlings which can be a nuisance over the landscape.
The male catskin are red or purple (shown left) and the photo above right shows a cross-section of an Eastern Cottonwood twig revealing the telltale inner “star”.
The Cottonwood tree bark is grayish-white. The base of the trunk on a mature Cottonwood exhibits medium deep furrowed bark with broad, flat-topped ridges, while the upper portion of the trunk exhibits fairly smooth, thin bark. Younger trees possess smooth, thin bark throughout.
Additional Eastern Cottonwood Tree Info
- The Eastern Cottonwood is honored as the state tree of Kansas, Wyoming, and Nebraska.
- Cottonwood grows best in moist, well-drained, fine sand or silt loams. This explains why you see them quite prominently along Lake Michigan sand dune environments.
- The wood is very soft, light, and brittle, often used for pallets, crates, and furniture frames.
- Cottonwoods are among North America’s fastest-growing trees, often growing 6 feet or more in height in a single year.
- Eastern Cottonwoods typically live 70–100 years, but they have the potential to live 200-400 years in ideal conditions.
7. Paper “White” Birch Tree (Betula papyrifera)
Leaves
- Shape: Rounded heart shape very similar to the Quaking Aspen, but has a more pointed tip.
- Edges: More sharply toothed than the Cottonwood or Quaking Aspen, more double serrated and displays a slightly rounded base.
- Other: Measures 2-4 inches in diameter, fairly thin leaf, medium green, often hairy on the veins underside, dull matte surface.
White Birch Tree Form and USDA Distribution Map
Paper “White” Birch Tree Size and Form – Large tree growing up to 80 feet (24 m) high and up to 50 feet (15 m) wide, forming in youth a compact, pyramidal or oval crown of many slender branches ending in very fine branchlets; frequently grows as a multi-trunked or multi-stemmed cluster, though it can also be found as a single-trunked tree. In old age can develop a long, branchless trunk with a broad, open crown composed of a few large limbs ascending to an acute angle, with almost horizontal branches.
Paper “White” Birch Autumn Leaves and Distribution Map
Paper Birch’s autumn colored leaves typically range from golden yellow to golden brown.
Paper “White” Birch tree bark displays distinct white to grayish-white bark with fine horizontal lines. Older trees exhibit thin curled-back sheets that can be peeled off. Sometimes the bark turns dark brownish-black near the ground. The bark makes the tree recognizable from a fair distance.
Additional Paper “White” Birch Tree Info
- Paper Birch trees are also known as American White Birch and Canoe Birch.
- Paper Birch is often one of the first species to colonize a burned area within the northern latitudes and is an important species for moose browsing. The wood is often used for pulp and firewood.
- Paper Birch trees have many similarities with Cottonwood and Aspens but do not belong to the poplar family.
- They are a short-lived species of birch native to the northern regions of North America typically living for 60–100 years, rarely exceeding 140–200 years.
8. Black Cherry Tree (Prunus serotina)
Leaves
- Shape: Oblong and narrow with abruptly pointed end.
- Edges: Finely toothed, teeth incurved.
- Other: Measures 2-6 inches long, moderately thick and leathery leaf; medium to dark green, paler underside, glossy surface.
- Note: The Black Cherry tree leaf can be confused with Ash and Beech tree leaves. Observe how the leaves are attached along the stem. The Black Cherry tree leaves grow alternately along the stem (see photo above). The Ash and Beech tree leaves grow opposite across from one another along the leaf twig.
Wild Black Cherry Tree Form and USDA Plant Datatbase Distribution Map
Black Cherry Tree Size and Form – The Black Cherry is a medium-sized tree, up to 65 feet (20 m) high and 50 feet (15m) wide. The trunks of open-grown trees are typically crooked with low-branching; the trunks in forest stands are slender, relatively straight, and free of lower branches; branches are few, large, crooked, and form a rather spreading, oblong or rounded crown.
Wild native Black Cherry tree autumn leaf most commonly turns deep yellow!
The Black Cherry tree flower is white with yellow pistils, shaped oblong and has an extremely pleasant aroma.
The Black Cherry tree fruit is safely edible and nutritious when fully ripe turning dark purple or black. The flesh has a tart, slightly bitter flavor, often used for jellies, jams, syrup, or pies. Do not consume pits, leaves or twigs.
Black Cherry tree bark is very useful for identifying this tree. Mature trees possess dark gray to almost black bark with a uniquely rough texture exhibiting turned-up checkered-like flakes; young trees are grayish brown with intermittent horizontal lines.
Additional Black Cherry Tree Info
- The Black Cherry is the largest of all other cherry tree varieties in Michigan and its outlying states.
- The wood is a valuable commodity for cabinet and furniture making.
- More than 33 species of birds, along with mammals like deer, squirrels, and black bears, rely on Black Cherry tree fruit.
- The tree hosts over 450 species of butterflies and moths, making it a critical hub for biodiversity.
- Wild Black Cherry trees live for 65-100 years, although they can survive for over 200–250 years in ideal, mature forest conditions.
9. Silver Maple (Acer saccharinum)
Leaves
- Shape: 5 main lobes with pointed tips; sinuses are narrow where lobes meet extending deeper past mid-leaf compared Red Maple or Sugar Maple
- Edges: Smooth between numerous serrations; more wide coarse than the Red Maple
- Other: Measure 4-7 inches long and almost as broad; fairly thin leaf, topside is medium green, underside of the leaf is whitish or silvery green and quite paler in comparison to the front side, also distinguishing them from their cousin maples; semi-glossy surface
- Note: The stems are long causing the leaves to flutter during windy days showing the colors between dark and light green.
Comparing Leaves of Silver Maple (bottom left) to Sugar Maple (top) and Red Maple (bottom right)
Silver Maple Tree USDA Distributions Map
Silver Maple Tree Size and Form – Large tree growing up 80 feet (24 m) high and up to 60 feet (18 m) wide. The trunk sometimes separates near the ground into three to four upright stems which are often branch-free for a considerable distance; long, slender branches bend downward, but with their tips ascending in a graceful curve upward. When the tree is unobstructed the crown can be wide-spreading and broad.
Silver Maple Tree Autumn Colors
Primarily, Silver Maple Tree autumn leaves turn shades of yellow, but depending on the location, they can also turn red with yellow tips as my neighbors Silver Maple tree in the photo above. Often, here in Michigan, the Silver Maple leaves are slower to get their seasonal colors compared to other maple varieties, and more often than not, they lose their leaves before their colors can change. But, depending on their location, they can be just as spectacular as their cousin varieties.
Silver Maple Bark on Mature Trees
The Silver Maple tree bark at maturity reveals a silvery-gray tone with dense flaky, elongated plates that are often free at both ends. Children and adults alike are tempted to peel the flakes. The younger trees have much smoother and thinner bark as with the Silver Maple’s cousins, the Sugar Maple and Red Maple.
Additional Silver Maple Tree Info
- Silver Maple trees appear as a dominant species only in streamside communities or on the fringes of lakes. Occasionally, they are found in swamps, gullies, and small depressions of slow drainage. Generally, they’re unable to compete with other species in upland environments. Even though they are native to the Central and Eastern regions of the United States, you’re more likely to see Silver Maples along city streets, in parks, and in suburban yards. They have been recommended by nurseries for their fast growth rate.
- A fast growing, relatively medium-lived tree typically 100-130 years, though they can exceed 150 years under ideal, undisturbed conditions.
10. American Basswood Tree (Tilia Americana)
Leaves
- Shape: Oval or heart shaped coming to a sharp point at the tip; exhibits a unique uneven, diagonal base.
- Edges: Toothed edges are coarse to finely serrated or jagged; sharp teeth typically point forward toward the leaf tip.
- Other: Large leaf measuring 5-8 inches (12-20 cm) long and wide; firm thick leaf, dark green topside, considerabley lighter green underside; glossy surface
American Basswood Tree and USDA Distribution Map
American Basswood Tree Size and Form – Large, fast growing tree, typically reaching from 60 to 80 feet (18-24 m) high, but can reach up to 130 feet (40 m) in ideal conditions; typically growing 40–50 feet (13-15 m) in width, or sometimes more. Young trees are pyramidal giving way to more columnar form when mature. Lower branches may droop.
The round leaf bracts support the development of flowers in early summer and, after pollination, help the small, nut-like fruit disperse in the wind, acting as a parachute. The bracts assist identification of the American Basswood tree!
American Basswood tree leaf autumn color transforms to a bright yellow.
American Basswood tree bark is grayish-brown to brown. When mature, the outer bark forms numerous narrow, fairly deep elongated fissures with flat topped ridges.
- Native Americans and settlers used the fibrous inner bark (“bast”), hence the name “bass”, for rope making, mats, fish nets, coverings for wigwams and baskets making.
Additional American Basswood Tree Info
- Is also known as a ‘Honey Tree” and “American Linden” is another common name.
- Linden is the original family name of the Swedish botanist, Carl Linnaeus, in which the tree is named after.
- Is considered a soft, light wood type.
- Is easy for carving uses.
- Is moderately shade tolerant.
- Associated with the Great Lakes timber industry for pulp, veneer, boxes, and more.
- Bees gather nectar from summer flowers; has been called the “Bee Tree”.
- Wildlife nest in openings of the trunks.
- Native Americans made medicinal tea from the leaves and flowers to treat burns, swelling, headaches, and indigestion.
- Fast growing Basswood Trees typically live for about 100-150 years, though they can survive for up to 200 years or more under ideal conditions.
