Understanding Missouri's Tree Species
Missouri boasts over 100 species of trees, categorized broadly into two main types: deciduous and coniferous. Deciduous trees shed their leaves annually, while coniferous trees retain their needles throughout the year.
Deciduous Trees
Deciduous trees are the most common in Missouri, thriving in a variety of environments, from forests to urban areas. Here are some of the most prevalent species:
- Oaks (Quercus spp.): There are several species of oaks in Missouri, including the Northern Red Oak and the White Oak. They are characterized by lobed leaves and acorns.
- Maples (Acer spp.): The Sugar Maple and Red Maple are popular for their vibrant fall foliage and are easily recognized by their broad, palmate leaves.
- Hickories (Carya spp.): Known for their hard wood and edible nuts, Hickories have compound leaves and are often found in mixed forests.
- Walnuts (Juglans spp.): The Black Walnut is common in Missouri and is recognized by its large, pinnate leaves and distinctive round fruit.
Coniferous Trees
Coniferous trees, while less common than deciduous trees, play a significant role in Missouri’s ecosystem. They are often found in areas with poor soil or as part of mixed forests. Notable coniferous trees include:
- Pines (Pinus spp.): The Eastern White Pine and Loblolly Pine are common in Missouri, characterized by their long needles and cones.
- Spruces (Picea spp.): The White Spruce is often planted for ornamental purposes, with short, stiff needles and hanging cones.
- Cedars (Thuja spp.): The Eastern Red Cedar is not a true cedar but is a juniper. It has scale-like leaves and produces berries.
Key Identification Features
When identifying trees, several features can help distinguish them. Here are the primary characteristics to observe:
Leaves
The shape, size, and arrangement of leaves are crucial in identifying a tree species.
- Leaf Shape: Leaves can be broad, needle-like, or scale-like.
- Leaf Arrangement: Observe whether the leaves are opposite, alternate, or whorled on the stem.
Bark
The texture and color of bark can vary significantly between species and can be an important identification feature.
- Texture: Bark may be smooth, scaly, or deeply furrowed.
- Color: Colors can range from light gray to dark brown or even reddish.
Flowers and Fruits
The reproductive structures of trees can also aid in identification.
- Flowers: The presence, color, and shape of flowers can be distinctive.
- Fruits: Acorns, nuts, berries, and cones are common in many species.
Common Trees in Missouri
To further assist you in identifying trees, here's a look at some of the most common species found in Missouri, along with their identifying features.
1. Northern Red Oak (Quercus rubra)
- Leaves: Lobed with pointed tips; dark green in summer, turning red in fall.
- Bark: Dark, ridged bark; smooth on younger trees.
- Habitat: Prefers well-drained, acidic soils in upland forests.
2. Sugar Maple (Acer saccharum)
- Leaves: Broad, palmate leaves with five lobes; vibrant yellow to red in fall.
- Bark: Gray, with smooth to slightly furrowed texture.
- Habitat: Thrives in rich, moist soils in deciduous forests.
3. Black Walnut (Juglans nigra)
- Leaves: Compound leaves with 15-23 leaflets; leaflets are lance-shaped.
- Bark: Dark brown, with deep furrows and ridges.
- Habitat: Common in rich, moist soils along riverbanks.
4. Eastern White Pine (Pinus strobus)
- Leaves: Long, slender needles grouped in clusters of five.
- Bark: Light gray and smooth when young, becoming thick and furrowed with age.
- Habitat: Prefers sandy, well-drained soils; often found in upland areas.

Frequently Asked Questions
What are the most common tree species found in Missouri?
Some of the most common tree species in Missouri include the oak, hickory, maple, sycamore, and sweetgum.
How can I identify a tree in Missouri by its leaves?
You can identify a tree by examining the shape, size, and arrangement of its leaves. Many resources, including field guides and online databases, provide images and descriptions to help with identification.
Are there any mobile apps available for tree identification in Missouri?
Yes, apps like iNaturalist and Leafsnap can assist in identifying trees by allowing users to upload photos and receive identification feedback.
What is the best time of year to identify trees in Missouri?
The best time for tree identification in Missouri is during spring and summer when leaves are fully developed, but fall can also be useful for identifying trees by their fruit and bark.
What resources are available for learning about Missouri trees?
Resources include field guides, websites like the Missouri Department of Conservation, local extension services, and community workshops on tree identification.
How does bark help in identifying Missouri trees?
Bark characteristics, such as texture, color, and pattern, can provide significant clues to a tree's identity, especially in winter when leaves are absent.
Are there any endangered tree species in Missouri?
Yes, species like the Eastern cottonwood and the American elm have been classified as endangered or threatened in certain areas of Missouri due to habitat loss and disease.
Can I use tree size to help identify species in Missouri?
Absolutely! The size, height, and trunk diameter of a tree can help narrow down species, as some trees have distinct size characteristics.
What should I do if I suspect a tree is diseased?
If you suspect a tree is diseased, consult a local arborist or extension service for advice, and consider using resources from the Missouri Department of Conservation for specific tree health issues.
