Why Bother Identifying Hickory?

“Why all the fuss about hickory?” you might ask. Well, hickory is a champion among hardwoods. Known for its strength, shock resistance, and density, it’s a prized wood for tool handles, flooring, smoking meats, and high-heat firewood. However, not all hickory is created equal. Identifying the species correctly allows you to select the right wood for the right job, maximizing its potential and avoiding costly mistakes. Plus, knowing your trees is just plain cool!

The Leaves Tell the Tale: Hickory Leaf Identification 101

Let’s get down to the nitty-gritty. Hickory leaves are compound, meaning they are composed of multiple leaflets attached to a single stem (the rachis). This is your first clue.

Leaf Arrangement: Hickory leaves are arranged alternately on the branch. This means that leaves don’t grow directly across from each other.
Number of Leaflets: Most hickory species have between 5 and 17 leaflets. The number can vary slightly, even on the same tree, but it’s a good starting point.
Leaflet Shape and Size: This is where things get interesting. Different hickory species have different leaflet shapes and sizes.
- Shagbark Hickory (Carya ovata): Typically has 5 leaflets, with the terminal (end) leaflet being significantly larger than the others. The leaflets are ovate (egg-shaped) to obovate (reverse egg-shaped) with serrated (toothed) edges. The bark is a key identifier, but more on that later.
- Pignut Hickory (Carya glabra): Usually has 5-7 leaflets. The leaflets are lance-shaped and smooth. The terminal leaflet is not much larger than the others.
- Mockernut Hickory (Carya tomentosa): Boasts 7-9 leaflets, which are densely hairy, giving the leaves a velvety texture. This is a distinguishing characteristic.
- Bitternut Hickory (Carya cordiformis): Features 7-11 leaflets that are slender and lance-shaped. The terminal buds are distinctively sulfur-yellow.
Leaflet Edge: Observe the edges of the leaflets closely. Are they finely serrated, coarsely serrated, or smooth? This detail can help narrow down the species.
Fall Color: Hickory leaves turn a beautiful golden-yellow to brownish-yellow in the fall. While not a definitive identifier, it adds another piece to the puzzle.

Beyond the Leaves: A Holistic Approach to Hickory Identification

While leaves are helpful, relying on them alone can be tricky. Consider these other factors:

Bark Characteristics

The bark is a crucial identifier, especially in winter when leaves are absent.

Shagbark Hickory: The name says it all. The bark peels off in long, shaggy plates, giving the tree a distinctive appearance. I’ve always found it easy to spot a shagbark from a distance, even in a dense forest.
Pignut Hickory: The bark is tight and ridged, with interlacing ridges. It’s generally smoother than shagbark.
Mockernut Hickory: The bark is tight and deeply furrowed, with a diamond-shaped pattern.
Bitternut Hickory: The bark is tight and relatively smooth, with shallow fissures.

Twigs and Buds

Examine the twigs and buds.

Shagbark Hickory: Twigs are stout and hairy. Terminal buds are large and scaly.
Pignut Hickory: Twigs are slender and relatively smooth. Terminal buds are small and pointed.
Mockernut Hickory: Twigs are stout and hairy. Terminal buds are large and densely hairy.
Bitternut Hickory: Twigs are slender and smooth. Terminal buds are long, slender, and sulfur-yellow. This is a key identifier.

Nuts

Hickory nuts are a valuable resource for wildlife and humans. Their appearance can help with identification.

Shagbark Hickory: Nuts are round, thick-shelled, and have a sweet, edible kernel.
Pignut Hickory: Nuts are pear-shaped, thin-shelled, and often have a bitter or astringent taste. Hence the name “pignut.”
Mockernut Hickory: Nuts are round, thick-shelled, and have a small, sweet kernel.
Bitternut Hickory: Nuts are round, thin-shelled, and have a very bitter kernel.

Habitat

Consider the tree’s habitat. Different hickory species prefer different growing conditions.

Shagbark Hickory: Prefers rich, moist soils in upland forests.
Pignut Hickory: Adaptable to a wide range of soils, from dry to moist. Often found on ridges and slopes.
Mockernut Hickory: Prefers dry, well-drained soils in upland forests.
Bitternut Hickory: Thrives in moist, bottomland forests.

Case Study: Identifying Hickory in My Own Woodlot

I manage a small woodlot in the Appalachian Mountains. Over the years, I’ve developed a keen eye for identifying hickory species. One day, I was walking through my woodlot when I came across a tree with compound leaves. The leaves had 7 leaflets, were densely hairy, and the bark was deeply furrowed. Based on these characteristics, I identified it as a mockernut hickory. Later in the fall, I collected some nuts. They were round, thick-shelled, and had a small, sweet kernel, confirming my initial identification.

Top Wood Species ID Tips: Expanding Your Knowledge

Hickory is just one piece of the puzzle. Here are some general tips for identifying wood species:

Use a Dichotomous Key: Dichotomous keys are tools that use a series of paired statements to guide you to the identification of a species. They are available for trees, shrubs, and other plants.
Carry a Field Guide: A good field guide will provide detailed descriptions and illustrations of different tree species.
Take a Class: Consider taking a tree identification class from a local college, university, or nature center.
Join a Forestry Group: Joining a forestry group is a great way to learn from experienced professionals and enthusiasts.
Practice Regularly: The more you practice, the better you’ll become at identifying trees.

Wood Properties and Uses: Why Identification Matters

Knowing the species of wood you’re working with is crucial for several reasons.

Strength and Durability: Different species have different strength and durability characteristics. Hickory is known for its strength and shock resistance, making it ideal for tool handles.
Workability: Some species are easier to work with than others. Softwoods like pine are generally easier to cut and shape than hardwoods like oak or hickory.
Appearance: Different species have different colors, grain patterns, and textures. This can affect the aesthetic appeal of your finished product.
Firewood Value: Different species have different heat values. Hickory is considered one of the best firewoods due to its high density and heat output.
