Tree Selection

Part of Woodworking

Before you pick up an axe, you need to pick the right tree. Choosing well means less work, stronger results, and wood that actually suits your project. Choosing poorly means splitting, warping, and wasted effort.

Why Tree Selection Matters

Every woodworking failure can be traced back to one of two causes: bad technique or bad wood. You can control both, but selecting the right tree is the easier problem to solve — if you know what to look for.

Different trees produce wood with wildly different properties. Oak resists rot for decades. Willow snaps under load. Pine carves easily but dents if you look at it wrong. Matching the species to the job is the single most important decision in any woodworking project.

Reading a Standing Tree

Bark

Bark tells you species, age, and health at a glance.

Bark Feature	What It Tells You
Deep furrows	Mature tree, likely larger heartwood core
Smooth, tight bark	Young or thin-barked species (birch, beech)
Peeling or loose bark	Possible disease, insect damage, or natural shedding
Fungal brackets	Internal rot — avoid for structural use
Oozing sap or dark stains	Active disease or insect boring

Leaves and Branching

Leaves confirm species when bark alone is ambiguous. Broad leaves generally mean hardwood (deciduous). Needles generally mean softwood (conifer). But identification matters beyond the broad category:

• Opposite branching (branches in pairs): maple, ash, dogwood
• Alternate branching (branches staggered): oak, birch, walnut, most others
• Leaf shape: lobed (oak, maple), compound (ash, walnut, hickory), simple oval (beech, elm)

Winter Identification

When leaves are gone, look at bud shape, bark pattern, and overall silhouette. Oaks hold dead leaves into winter. Beech holds pale tan leaves. Ash has distinctive black buds.

Trunk Assessment

Stand back and look at the whole trunk before committing:

• Straight trunk: Best for boards, beams, and dimensional lumber. Look for at least 8-10 feet of clear, straight trunk below the first major branch.
• Slight curve: Acceptable for many projects. Can be split to follow the curve for natural knee braces or boat ribs.
• Heavy lean: The wood on the compression side (underside of lean) will be stressed and prone to unpredictable splitting. Use cautiously.
• Spiral grain: Look at bark furrows — if they twist around the trunk, the grain inside twists too. Avoid for anything structural. Acceptable for firewood.
• Fork/crotch: The junction where the trunk splits creates beautiful figure but wildly unpredictable grain. Good for decorative pieces, terrible for structural work.

Growth Patterns and Grain

Straight vs. Curved Grain

Straight grain splits cleanly, planes smoothly, and holds fasteners well. It comes from trees that grew in competition with neighbors — reaching straight up for light.

Curved or interlocked grain comes from trees that grew in the open, twisted in wind, or are genetically predisposed to spiral growth. Elm and some tropical species almost always have interlocked grain.

Reading Annual Rings

If you can see a cut stump or cross-section:

• Wide, even rings: Fast growth, softer wood, easier to work but less strong
• Tight, even rings: Slow growth, denser wood, stronger but harder to work
• Uneven rings (wide on one side): Tree was leaning or competing for light on one side — expect reaction wood
• Very tight rings near center, wide outside: Tree was suppressed then released — mixed properties

Reaction Wood

Trees that grew leaning or in heavy wind develop reaction wood. In softwoods, it’s called compression wood (on the underside) — it’s brittle and dense. In hardwoods, it’s tension wood (on the upper side) — it’s fuzzy and hard to plane. Both are problems. Avoid heavily leaning trees for quality lumber.

Assessing Health and Defects

Walk around the entire tree before felling. Check:

Rot

• Base rot: Tap the base with the back of your axe. A solid thud means sound wood. A hollow drum sound means internal rot.
• Top rot: Look for dead branches, broken tops, or fungal growth high up. Rot works downward from entry points.
• Heart rot: Common in old trees. The heartwood decays while sapwood stays sound. You may not know until you cut. If the tree is very old and the species is prone to heart rot (most hardwoods over 100 years), expect it.

Insect Damage

• Bark beetle galleries: Remove a small patch of loose bark. Tunnels etched into the surface mean bark beetles. Wood may still be usable if damage is shallow.
• Powder post beetles: Tiny round holes (1-2mm) with fine dust. These bore deep. Structural use is risky.
• Carpenter ants: Large irregular galleries, usually at the base. Wood is weakened significantly.

Crotches and Included Bark

Where two stems meet, bark sometimes gets trapped between them (included bark). This creates a weak point — the two stems are not actually joined by wood fibers. Avoid these for structural timber. The wood around a crotch often has beautiful crotch figure prized for veneer and turning, but it’s unpredictable to work.

Matching Species to Purpose

Purpose	Best Species	Why
House framing	Pine, spruce, fir, oak	Straight, strong, available in long lengths
Fence posts	Black locust, white oak, cedar	Natural rot resistance
Tool handles	Ash, hickory	Flexible, absorbs shock
Furniture	Oak, cherry, walnut, maple	Hard, beautiful, takes finish well
Carving	Basswood, butternut, white pine	Soft, even grain, holds detail
Bending (steam)	White oak, ash, beech, elm	Long fibers resist breaking
Firewood	Oak, hickory, maple, ash	Dense, high heat, long burn
Quick fuel	Pine, poplar, willow	Burns fast and hot, easy to split
Water contact (boats, troughs)	White oak, elm, cypress, cedar	Rot resistant or water-tight grain
Pegs and dowels	Oak, locust, hickory	Hard, strong in shear

When to Fell

Season

• Winter (dormant season): Best for most purposes. Sap is down, moisture content is lower, bark beetles are inactive, and the wood seasons faster. Historically, winter-felled timber was considered superior.
• Late spring/summer: Bark peels easily (useful for bark crafts or log building where you want to debark). But moisture content is highest and insect/fungal attack risk is greatest.
• Avoid: Felling during active sap flow (early spring) if you need the wood to last. Sugar-rich sap feeds mold and insects.

Moon Phase

Traditional timber lore says to fell on a waning moon. Modern forestry finds no measurable difference. Fell when conditions are safe and the ground is accessible.

Practical Considerations

• Fell when the ground is frozen or dry — dragging logs through mud damages them and the forest floor
• Fell when you have time to process the tree promptly — logs left in contact with the ground rot fast
• Fell when you have a clear work area and help if needed

Start Small

If you are new to tree selection, start with a tree you can identify with certainty. Use it for a low-stakes project. Note how it splits, dries, and works. Build your knowledge from direct experience, one species at a time.

Common Mistakes

1. Choosing the biggest tree: Bigger is not better. Large old trees often have heart rot, reaction wood, and heavy branches that make felling dangerous. A straight 10-inch diameter tree often yields better lumber than a 24-inch giant.

2. Ignoring lean: A tree leaning 15 degrees has enormous tension on one side. That wood will behave unpredictably.

3. Selecting dead standing trees: Dead wood can be excellent (naturally seasoned) or terrible (insect-riddled and punky). Tap-test before committing. If it sounds hollow or the bark falls off in sheets, it is likely too far gone for anything but firewood.

4. Not planning end use first: Decide what you are building, then select the tree. Never select a tree and then figure out what to do with it — you will waste most of it.

Tree Selection — At a Glance

• Match species to project: rot-resistant for ground contact, flexible for handles, dense for furniture
• Read the trunk: straight grain, no spiral, minimal lean
• Check health: tap for rot, inspect bark for insects, look for fungal brackets
• Fell in winter for best results
• Start with trees you can positively identify
• A smaller, straighter tree beats a larger, defective one every time
