How To Fell A Tree In A Certain Direction (Expert Arborist Tips)

Ever notice how trees, even in a seemingly still forest, lean slightly toward the light, almost as if they’re perpetually stretching for a better view? That subtle lean, that natural inclination, can be a real head-scratcher when you’re trying to fell one in a specific direction. I’ve spent countless hours in the woods, wrestling with gravity, wind, and the stubborn will of trees, and I’m here to share my hard-earned wisdom on how to make a tree fall exactly where you want it to. It’s not just about brute force; it’s a dance between understanding wood, physics, and a whole lot of planning. This guide will equip you with the knowledge and techniques to confidently and safely fell trees with precision.

The Art and Science of Precision Tree Felling

Felling a tree accurately is crucial for a multitude of reasons. It’s not just about aesthetics; it’s about safety, efficiency, and minimizing environmental impact. A misdirected fall can damage property, injure personnel, or create unnecessary obstacles in the forest.

Why Directional Felling Matters

Safety: Controlling the fall direction minimizes the risk of hitting structures, power lines, or other trees.
Efficiency: Falling trees in a planned direction streamlines the logging or firewood harvesting process.
Environmental Impact: Precise felling reduces damage to surrounding vegetation and soil disturbance.
Property Protection: Directing the fall away from buildings, fences, and other valuable assets prevents costly repairs.
Terrain Considerations: In steep or uneven terrain, directional felling is essential for controlling the tree’s descent and preventing it from rolling or sliding uncontrollably.

Understanding Tree Anatomy and Lean

Before even thinking about firing up your chainsaw, you need to become intimately familiar with the tree you’re about to fell. Understanding its anatomy and natural lean is paramount.

Overhead Hazards: Check for dead branches, power lines, or other obstructions that could fall during the felling process.
Ground Hazards: Identify rocks, stumps, holes, or uneven terrain that could cause you to stumble or lose your footing.
Escape Routes: Plan two clear escape routes at a 45-degree angle away from the intended fall direction.
Wind Conditions: Wind can significantly alter the tree’s fall direction. Never fell trees in high winds.
Surrounding Trees: Evaluate the proximity of other trees and the potential for the felled tree to snag or damage them.

Essential Tools and Equipment

Having the right tools is as crucial as knowing how to use them.

Chainsaw Selection and Maintenance

Chainsaw Size: Choose a chainsaw with a bar length appropriate for the diameter of the tree. A general rule of thumb is that the bar length should be at least two inches longer than the tree’s diameter.
Chainsaw Type: For most felling operations, a professional-grade chainsaw with a powerful engine is recommended.
Chain Sharpness: A sharp chain is essential for safe and efficient cutting. Sharpen your chain regularly and carry a spare.
Chainsaw Maintenance: Regularly inspect and maintain your chainsaw, including checking the chain tension, lubricating the bar, and cleaning the air filter.

Personal Protective Equipment (PPE)

Helmet: A hard hat is crucial for protecting your head from falling debris.
Eye Protection: Safety glasses or a face shield will protect your eyes from wood chips and sawdust.
Hearing Protection: Earplugs or earmuffs will protect your hearing from the loud noise of the chainsaw.
Chainsaw Chaps: Chainsaw chaps are designed to protect your legs from chainsaw cuts.
Gloves: Gloves provide a better grip and protect your hands from cuts and abrasions.
Steel-Toed Boots: Steel-toed boots will protect your feet from falling objects and chainsaw cuts.

Felling Wedges and Levers

Felling Wedges: Felling wedges are used to lift the tree and help direct its fall. They are available in plastic, aluminum, and steel. Plastic wedges are generally preferred because they are less likely to damage the chainsaw chain if accidentally contacted.
Felling Levers: Felling levers provide additional leverage for lifting the tree and directing its fall. They are particularly useful for felling larger trees.

Other Essential Tools

Measuring Tape: A measuring tape is essential for accurately measuring the tree’s diameter and determining the appropriate cut depths.
Axe or Hatchet: An axe or hatchet can be used to clear brush and remove small branches.
First Aid Kit: A well-stocked first aid kit is essential for treating minor injuries.
Communication Device: A cell phone or two-way radio is important for communicating with others in case of an emergency.

Mastering the Felling Cuts

The felling cuts are the heart of the operation. Precision and accuracy are paramount.

The Open Face Notch

The open face notch is a crucial cut that determines the direction of the fall. It consists of two cuts: the top cut and the bottom cut.

Top Cut: The top cut should be made at a 45-degree angle, sloping downward into the tree. The depth of the top cut should be approximately 20% of the tree’s diameter.
Bottom Cut: The bottom cut should be made horizontally, meeting the top cut at the desired depth. The notch should be wide enough to allow the tree to fall freely.
Notch Alignment: The notch should be precisely aligned with the intended fall direction. Use a sighting tool or simply align the notch with a distant object.

The Hinge

The hinge is a strip of uncut wood that connects the stump to the falling tree. It controls the speed and direction of the fall.

Hinge Width: The width of the hinge should be approximately 80% of the tree’s diameter.
Hinge Thickness: The thickness of the hinge should be uniform and consistent.
Hinge Placement: The hinge should be placed directly behind the notch, ensuring that it is aligned with the intended fall direction.

The Back Cut

The back cut is the final cut that severs the tree from the stump.

Back Cut Height: The back cut should be made slightly above the bottom cut of the notch, leaving a hinge of the appropriate width and thickness.
Back Cut Depth: The back cut should be made deep enough to sever the tree, but not so deep that it cuts into the hinge.
Leaving the Hinge: It is crucial to leave the hinge intact. The hinge acts as a guide, controlling the fall of the tree and preventing it from twisting or kicking back.

Using Felling Wedges

Felling wedges are used to lift the tree and help direct its fall, particularly when the tree is leaning in the wrong direction or when there is a risk of the tree sitting back on the saw.

Wedge Placement: Insert the felling wedges into the back cut, behind the chainsaw bar.
Wedge Driving: Drive the wedges in evenly, using a hammer or axe. As the wedges are driven in, they will lift the tree and help direct its fall.
Multiple Wedges: For larger trees, multiple wedges may be necessary.

Advanced Techniques for Challenging Trees

Sometimes, trees present unique challenges that require more advanced techniques.

Dealing with Back Lean

A tree with a significant back lean can be extremely dangerous to fell. Here are some techniques to mitigate the risk:

Winching: Use a winch to pull the tree in the desired direction before making the back cut.
Counter-Weighting: Attach a heavy weight to the opposite side of the tree to counteract the lean.
Pie Cutting: Remove a pie-shaped section of wood from the side of the tree opposite the lean to encourage it to fall in the desired direction.

Addressing Side Lean

Side lean can be corrected using similar techniques as back lean, but with the forces applied laterally.

Winching: Use a winch to pull the tree in the desired direction before making the back cut.
Felling Lever: Use a felling lever to provide additional leverage and help direct the fall.
Strategic Wedging: Place wedges strategically to lift and direct the tree’s fall.

Handling Trees with Uneven Weight Distribution

Trees with heavy branches on one side or asymmetrical crowns require careful planning and execution.

Branch Removal: Remove heavy branches on the side of the tree that you want to fall away from.
Strategic Cutting: Adjust the depth and angle of the felling cuts to compensate for the uneven weight distribution.
Winching: Use a winch to pull the tree in the desired direction before making the back cut.

Managing Trees with Rot or Decay

Trees with rot or decay are unpredictable and can be extremely dangerous to fell.

Careful Inspection: Thoroughly inspect the tree for signs of rot or decay before attempting to fell it.
Reduced Hinge: Reduce the width of the hinge to compensate for the weakened wood.
Increased Caution: Exercise extreme caution and be prepared for the tree to fall unexpectedly.

Safety First: Preventing Accidents

Safety is paramount in all aspects of tree felling. Never compromise on safety protocols.

Pre-Felling Safety Checklist

Site Assessment: Conduct a thorough site assessment to identify potential hazards.
Equipment Inspection: Inspect all equipment to ensure it is in good working condition.
PPE Check: Ensure that all personnel are wearing appropriate PPE.
Emergency Plan: Develop an emergency plan and communicate it to all personnel.
Weather Conditions: Monitor weather conditions and avoid felling trees in high winds or other adverse weather.

Safe Cutting Practices

Proper Stance: Maintain a stable stance with your feet shoulder-width apart.
Firm Grip: Maintain a firm grip on the chainsaw with both hands.
Avoid Overreaching: Avoid overreaching or cutting above shoulder height.
Watch for Kickback: Be aware of the risk of chainsaw kickback and take precautions to avoid it.
Clear the Area: Ensure that the area around the tree is clear of people and obstacles.

Post-Felling Safety Procedures

Assess the Fall: After the tree has fallen, assess the situation and identify any potential hazards.
Limbing and Bucking: Limb and buck the tree safely, following proper procedures.
Clean Up: Clean up the area, removing any debris or hazards.
Report Incidents: Report any incidents or near misses to the appropriate authorities.

Case Studies: Real-World Felling Scenarios

Let’s look at some real-world examples of how these techniques are applied in different situations.

Case Study 1: Felling a Leaning Pine Near a Structure

Challenge: A large pine tree was leaning significantly towards a house. The tree was also located near a power line.
Solution: The arborist used a combination of winching and strategic cutting to direct the fall away from the house and power line. The tree was first winched in the opposite direction of the lean. Then, an open face notch was cut on the side of the tree facing the desired fall direction. Finally, a back cut was made, leaving a hinge of the appropriate width and thickness. The tree fell precisely as planned.
Lessons Learned: Careful planning and the use of specialized equipment can safely fell trees in challenging situations.

Case Study 2: Felling a Decayed Oak in a Forest

Challenge: An oak tree with significant decay was located in a dense forest. The tree was surrounded by other trees and had a large cavity in its trunk.
Solution: The arborist carefully inspected the tree and determined that it was too dangerous to fell using conventional methods. Instead, the tree was dismantled piece by piece, using a crane and ropes. Each section of the tree was carefully lowered to the ground, avoiding damage to the surrounding trees.
Lessons Learned: In some cases, the safest approach is to dismantle the tree rather than attempting to fell it in one piece.

Case Study 3: Felling Multiple Trees for Firewood

Challenge: A landowner needed to fell multiple trees for firewood. The trees were located on a hillside and varied in size and species.
Solution: The landowner used a combination of directional felling techniques and mechanized equipment to efficiently harvest the trees. The trees were felled in a planned sequence, minimizing damage to the surrounding forest. The felled trees were then processed into firewood using a log splitter and chainsaw.
Lessons Learned: Proper planning and the use of appropriate equipment can significantly increase the efficiency of firewood harvesting operations.
