Removing a dead tree is necessary because compromised trees pose a significant hazard to property and personal safety. Felling a tree is one of the most dangerous activities a homeowner can undertake, requiring precision and planning. This guide offers foundational knowledge for safely assessing a dead tree and executing the removal process in a controlled manner. The decay patterns of dead wood introduce unpredictable variables that demand elevated caution. A successful removal minimizes risk, controls the fall direction, and ensures the wood can be processed safely.
Assessing Instability and Determining When to Hire a Professional
Dead trees pose a heightened risk compared to live ones because the wood lacks the flexibility and structural integrity of living fiber. Internal decay, often invisible, creates weak points that can cause the tree to fail unexpectedly during cutting. A particularly dangerous feature is the “widowmaker,” a detached limb caught high in the canopy that can fall without warning, especially when the trunk vibrates from the chainsaw’s use.
Before cutting, assess the tree’s condition to determine if the job is suitable for a non-professional. Signs of severe instability include fungal growth or mushrooms on the trunk, deep vertical cracks, or missing bark, all indicating advanced internal rot. If the tree leans excessively or if its height means the top could strike a structure or power line, call a certified arborist immediately.
A professional is also necessary if the tree diameter is larger than the length of your saw’s bar, or if the tree is in a confined space requiring precise fall control. Certified arborists have the training and specialized equipment, such as ropes and winches, to manage hazards that exceed homeowner capability. Attempting to fell a compromised tree can lead to catastrophic results, making professional help an investment in safety.
Essential Safety Gear and Site Preparation
The use of appropriate personal protective equipment (PPE) is mandatory for all felling operations. Head protection is provided by a mountaineering-style helmet to guard against falling debris. Hearing protection (earmuffs or plugs) safeguards against noise damage, and eye protection (safety glasses or a face shield) guards against flying wood chips and sawdust.
The lower body must be protected with cut-resistant clothing, such as chainsaw chaps or pants, which contain ballistic nylon fibers designed to instantly clog the saw upon contact. Steel-toed boots with robust grip are required to protect the feet from dropped logs and ensure stable footing. Felling accessories like plastic or aluminum wedges are necessary to prevent the saw bar from pinching and to direct the tree’s fall.
Site preparation focuses on clearing the environment for a safe exit once the tree begins to move. The most important step is planning and clearing the escape route, which must be angled approximately 45 degrees away from the planned direction of the tree’s fall. This path should be free of underbrush, loose branches, or tripping hazards for at least 20 feet. Clearing the area also involves ensuring no bystanders are present and that all vehicles or structures in the fall zone are moved to a safe distance.
Executing the Directional Felling Cuts
Directional felling relies on creating a precise hinge of uncut wood to control the tree’s descent. First, establish the desired fall line and create the “face cut,” or directional notch, on the side facing the fall zone. The safest technique is the open-face notch, formed by a horizontal cut and a downward-sloping cut that meet cleanly to create an opening angle of 70 to 90 degrees. This wide angle keeps the hinge intact longer, guiding the tree until it is almost horizontal and preventing uncontrolled breaking.
The face cut should penetrate the trunk to a depth of one-third of the tree’s diameter. The remaining uncut wood, known as the “hinge,” steers the tree. Its thickness, measured along the direction of the fall, should be about 10% of the tree’s diameter at breast height (DBH).
After the notch is established, the “back cut” is made on the opposite side, aiming to stop at the predetermined hinge width. This cut should be made one to two inches above the apex of the notch, which prevents the butt of the tree from kicking back over the stump toward the operator. Once the back cut is deep enough to insert a wedge, remove the saw and drive a plastic or aluminum wedge into the cut with an axe to push the tree over the hinge and control the fall.
Processing the Fallen Tree and Cleanup
Once the tree is safely on the ground, processing begins with limbing, or removing the branches from the main trunk. Start this process from the base and move toward the top, using the trunk as a barrier between the operator and the chainsaw. When cutting branches, manage tension and compression forces, especially on limbs that are bent or pinned to the ground.
If a limb is elevated, tension is on the underside and compression is on the top. Cutting the compression side first can cause the bar to pinch. The safest practice is to make a small undercut on the compression side first to prevent binding, and then finish the cut from the tension side.
The trunk is then cut into manageable sections, known as bucking, applying the same principles. If a log is supported at both ends, the top is under compression and the bottom is under tension; the cut should begin on the compression side. For logs resting entirely on the ground, make cuts partially through the top, roll the log over, and finish the cut from the opposite side to avoid dulling the chain on the soil. The remaining stump can be handled by mechanical grinding for immediate removal, or by using chemical decomposition accelerators like potassium nitrate to speed up the natural rotting process.
