Assessing the Situation
Before attempting to cut a leaning tree, a thorough assessment of the situation is crucial to ensure safety and minimize risk. Consider the following factors:
1. Determine the Tree’s Lean
Measure the lean angle of the tree using a clinometer or a carpenter’s level. The following table provides guidance on determining the risk associated with different lean angles:
| Lean Angle | Risk Level |
|---|---|
| 0-10 degrees | Low – Generally safe to cut |
| 11-20 degrees | Moderate – Requires caution and proper technique |
| 21-30 degrees | High – Only recommended for experienced tree cutters |
| 30+ degrees | Extreme – Do not cut without professional assistance |
2. Inspect the Tree’s Base and Surroundings
Examine the tree’s base for any signs of decay, cracks, or root damage. Also, note any buildings, power lines, or obstacles nearby that could be affected by the fall. Clear the area of loose debris and potential trip hazards.
3. Check the Tree’s Canopy
Assess the distribution and weight of the canopy. Heavy branches or an unbalanced canopy can significantly impact the fall direction. Identify any dead or dying branches that may break off during the cut.
4. Consider the Weather and Ground Conditions
Avoid cutting trees in windy or wet conditions, as this can increase the risk of the tree falling unexpectedly or slipping during the cut. Soft or uneven ground can also compromise stability and make the cutting process more hazardous.
Safety Considerations
Plan an Escape Route
Before starting, plan a clear escape route away from the direction the tree is likely to fall. This route should be downhill if possible and free of obstacles like branches or other trees. Make sure everyone involved in the tree felling process is aware of this escape route and is prepared to use it in case of need.
Inspect and Clear the Work Area
Inspect the work area for any hazards, such as downed power lines, loose branches, or tripping hazards. Clear away any obstacles to create a safe working space. If there are obstacles that you cannot safely remove, you should consider postponing the tree felling operation until you can get professional assistance.
Wear Appropriate Safety Gear
Proper safety gear is essential when felling a tree. This includes a hard hat, eye protection, earplugs or ear muffs, gloves, and sturdy work boots. The hard hat will protect your head from falling branches or debris, while the eye protection will guard against flying wood chips. Earplugs or ear muffs will prevent hearing damage from the noise of the chainsaw, and gloves will protect your hands from cuts and abrasions.
Gathering Necessary Equipment
Before embarking on the task of felling a leaning tree, it is imperative to gather the appropriate equipment to ensure both safety and efficiency.
Axes and Saws
Select a sharp axe for cutting limbs and a chainsaw or crosscut saw for felling the tree. A felling axe should be at least 3.5 pounds, while a chainsaw should have a bar length of at least 18 inches.
Wedges
Wooden or plastic wedges are essential for controlling the direction of the fall. Place them in the felling cut to prevent the tree from falling towards unintended areas.
Rope and Pulleys
Rope and pulleys can be used to assist in felling the tree, especially if it is leaning significantly. Pass a rope through the pulleys and attach it to the tree to help pull it in the desired direction.
Other Tools
Additional tools that may be useful include:
| Tool | Purpose |
|---|---|
| Wrenches | Tightening or repairing chainsaw |
| First-Aid Kit | Treating minor injuries |
| Safety Glasses and Earplugs | Protecting eyes and ears from debris |
| Whistle or Horn | Alerting others in the area of tree felling |
Notching the Tree
Make two cuts on the side of the tree facing the direction you want it to fall. The first cut should be about 1/3 of the way through the trunk, and the second cut should be 2-4 inches higher than the first and angled downward. The notch should be about 1/5 of the diameter of the tree.
Removing the Wedge
Once you have made the notch, use an axe or chainsaw to remove the wedge of wood between the two cuts. This will create a weak spot in the tree that will allow it to fall in the desired direction.
Cutting the Back Cut
The back cut is the final cut that will bring the tree down. It should be made on the opposite side of the tree from the notch, and it should be parallel to the notch. The back cut should be deep enough to reach the notch, but it should not be so deep that it severs the tree completely. This will cause the tree to hinge on the uncut wood and fall in a controlled manner.
Here are some tips for cutting a back cut:
| Tip |
|---|
| Start the back cut a few inches above the notch to avoid pinching the saw. |
| Cut slowly and carefully, making sure to follow the line of the notch. |
| Stop cutting when the saw reaches the notch to prevent the tree from falling prematurely. |
Back Cutting the Tree
Create a ‘back cut’ on the opposite side of the tree, about 6-8 inches (15.2 – 20.3 cm) higher than the notch. The back cut should be parallel to the front cut and about 1/4 of the way through the tree.
| Step | Description |
|---|---|
| 1 | Determine the correct height for the back cut by measuring 6-8 inches (15.2 – 20.3 cm) above the notch. |
| 2 | Position the saw parallel to the front cut and ensure it is level. |
| 3 | Carefully cut a horizontal line about 1/4 of the way through the tree, creating the back cut. |
| 4 | Monitor the tree’s movement and be prepared to remove the saw quickly if the tree begins to fall. |

Assessing the Cut
Before making the first cut, it is crucial to establish which direction the tree will fall. Several factors influence the tree’s natural fall line, including the lean of the tree, the weight distribution of the branches, and the wind direction.
Leaning Tree
Assess the tree’s lean by standing perpendicular to the trunk and observing the direction it is leaning. This will provide an approximate idea of the fall line. However, it is important to note that the lean may not be uniform throughout the tree’s height.
Branch Weight
Examine the weight distribution of the branches. Heavy branches on one side can pull the tree in that direction, affecting the fall line. Remove any large or overhanging branches that could interfere with the tree’s natural fall path.
Wind Direction
Consider the prevailing wind direction in your area. A strong wind can push the tree in its direction, potentially causing it to fall unexpectedly. If possible, fell the tree when there is little or no wind.
Additional Considerations
In addition to the primary factors mentioned above, several other considerations can influence the tree’s fall line:
- Soil conditions: Soft, wet soil can reduce the resistance to the tree’s fall.
- Root structure: A weak or damaged root system can make the tree more susceptible to falling in an unexpected direction.
- Adjacent trees: Nearby trees can provide support or resistance, affecting the fall line.
By carefully assessing these factors, you can determine the most appropriate direction to fell the leaning tree, ensuring a safe and controlled outcome.
Stump Removal (if necessary)
Once the tree has been felled, you may need to remove the stump. There are a few different ways to do this, including:
Manual removal
This involves digging around the stump and cutting through the roots with an axe or saw. This can be a lot of work, but it’s the most cost-effective option.
Chemical removal
This involves drilling holes in the stump and filling them with a herbicide. This will kill the stump over time, but it can be expensive and time-consuming.
Grinding
This involves using a stump grinder to grind the stump down to below ground level. This is the most expensive option, but it’s also the quickest and easiest way to remove a stump.
| Method | Cost | Time |
|---|---|---|
| Manual removal | Low | High |
| Chemical removal | Medium | Medium |
| Grinding | High | Low |
The best method for removing a stump will depend on the size of the stump, the location of the stump, and your budget. If you’re not sure which method is best for you, consult with a professional arborist.
Post-Cut Inspection
Once the tree has been felled, it’s crucial to conduct a post-cut inspection to ensure there are no hidden hazards or potential problems. Follow these steps for a thorough inspection:
- Examine the stump: Check the stump for signs of decay, rot, or other damage. Use a probe or screwdriver to gently tap the stump and listen for any hollow or soft spots.
- Inspect the root system: Expose the root system around the stump to check for exposed roots, root damage, or any signs of decay. Ensure the roots are healthy and not compromised.
- Look for cracks or splits: Inspect the trunk and branches for any cracks, splits, or fissures that may have occurred during the felling process. Large or deep cracks can indicate structural weakness and should be addressed.
- Check for leaning trees: Identify any nearby trees that may have been affected by the fallen tree or may be leaning towards it. Assess their stability and take necessary precautions, such as roping or cabling them.
- Remove debris and brush: Clear away any debris, such as branches, twigs, or brush, from the area where the tree was felled. This will help prevent tripping hazards and improve visibility for further inspection.
- Check for power lines: Be aware of any power lines in the area and ensure that the fallen tree hasn’t damaged or compromised them. Contact the utility company immediately if there are concerns.
- Inspect for hidden branches: Use a flashlight or mirror to inspect the underside of the stump and trunk for any hidden branches that may be under tension and could whip back when cut.
- Look for wildlife: Be cautious of wildlife that may have been disturbed by the felling process. Check for any nesting birds or animal dens in the tree or nearby and take appropriate action to avoid disturbing them.
- Assess the ground conditions: Examine the ground around the fallen tree for any signs of soil erosion, root upheaval, or other damage that may have occurred during the felling process.
- Take notes and photographs: Document your inspection findings by taking notes and capturing photographs to provide a record of the inspection and any potential hazards identified.
