Mastering Tennessee Tree Identification: A Guide to Bark Patterns

Embarking on a nature walk in Tennessee and eager to identify the trees you encounter? While leaves and flowers are helpful, the bark of a tree can be a year-round identifier and a fascinating study in itself. This guide will help you understand and recognize the unique bark patterns of some of Tennessee's most common trees.

Understanding Tree Bark

Tree bark serves several purposes: it protects the tree from physical damage, regulates water loss, and provides a habitat for various organisms. The texture, color, and patterns of bark can vary greatly among species, making it an excellent identifier. In Tennessee, you'll find a diverse range of bark types, from smooth and thin to rough and thick.

Tennessee's Common Tree Species and Their Bark

Eastern Red Cedar (Juniperus virginiana)

The Eastern Red Cedar is a popular evergreen in Tennessee, known for its scaly, reddish-brown bark. As the tree ages, the bark develops deep, vertical cracks, revealing a reddish inner bark. This tree is often mistaken for a cedar, but it's actually a juniper.

Tulip Poplar (Liriodendron tulipifera)

The Tulip Poplar, Tennessee's state tree, has a distinctive bark that exfoliates in thin, papery sheets, revealing a smooth, grayish inner bark. The outer bark is dark gray and rough, with deep, irregular furrows. This tree is deciduous, so its bark is visible year-round.

Sycamore (Platanus occidentalis)

The Sycamore is a striking tree with a mottled, exfoliating bark that reveals patches of white, green, and gray. The bark is thick and deeply furrowed, with a rough texture. In Tennessee, Sycamores are often found near waterways.

Sweetgum (Liquidambar styraciflua)

The Sweetgum tree has a smooth, gray bark when young, which becomes rough and deeply furrowed with age. The bark develops small, rounded projections called lenticels, which help the tree exchange gases. The Sweetgum is known for its star-shaped leaves and spiky, round fruit.

Hickory (Carya spp.)

Hickory trees have a thick, dark gray bark that is deeply furrowed and plated. The bark can be rough or smooth, depending on the species. Hickories are known for their strong, heavy wood and their edible nuts.

Bark Identification Tips

• Observe the texture: Is the bark smooth, rough, or scaly?
• Examine the color: What is the dominant color of the bark? Are there any patterns or variations?
• Look for unique features: Does the bark have lenticels, furrows, or exfoliation? Are there any distinctive growths or projections?
• Consider the tree's habitat: Where is the tree growing? Some trees are more common in certain habitats.
