Felling a tree is a task that demands skill, precision, and safety. A crucial part of this process is notching the tree correctly. This guide will explain the purpose of notches, the different types of tree felling notches, and how to notch a tree to cut it down safely and effectively.

What is Notching a Tree?
Notching a tree involves cutting a specific section out of the tree trunk to control the direction in which the tree will fall. This is a foundational step in tree felling, as it helps ensure the tree falls safely and predictably, minimizing damage to the surrounding area and reducing the risk of accidents.
Why is Notching Important?
The primary reason for notching is to guide the tree’s fall. By removing a wedge-shaped section from the tree trunk, you create a “hinge” on the opposite side of the notch. This hinge helps direct the tree’s fall and is crucial for maintaining control throughout the process.
Moreover, proper notching can prevent the tree from splitting and causing dangerous kickbacks. It also reduces the risk of the tree falling backward, which can pose significant hazards to the person cutting the tree and any nearby structures or vegetation.

Different Tree Felling Notches
There are several types of notches used in tree felling, each with its own specific applications and benefits. Understanding the differences between these notches will help you choose the right one for your needs.
The Conventional Notch
The conventional notch is one of the most commonly used notches. It consists of a horizontal cut and an angled cut, which meet to form a wedge removed from the tree trunk. This notch is typically used for trees that are not leaning heavily in any direction.
- Horizontal Cut: The horizontal cut is made parallel to the ground and should penetrate about one-third of the tree’s diameter.
- Angled Cut: The angled cut should be approximately 45 degrees, meeting the horizontal cut to remove a wedge of wood.
The Humbolt Notch
The Humbolt notch is similar to the conventional notch but is inverted. It is often used in commercial logging because it allows the tree to fall without breaking the log’s butt end, maximizing wood yield.
- Horizontal Cut: This cut is made on the lower side of the wedge, parallel to the ground.
- Angled Cut: The angled cut is made from below, forming an inverted wedge with the horizontal cut.
The Open Face Notch
The open face notch is designed to give the tree more room to fall, making it ideal for more precise felling. This notch is often used in situations where maximum control over the tree’s fall is required.
- First Cut: The first cut is made at an angle of about 70 degrees.
- Second Cut: The second cut is horizontal, meeting the angled cut to create an open wedge.
The open face notch offers a wider angle, allowing for a longer hinge that helps control the tree more effectively as it falls.
How to Notch a Tree to Cut Down
Notching a tree involves careful planning and execution. Follow these steps to ensure safety and precision:
Step 1: Assess the Tree and Surroundings
Before making any cuts, inspect the tree and its surroundings. Identify the tree’s natural lean and take note of any obstacles in the intended fall path. Ensure there is a clear escape route for you to retreat safely once the tree begins to fall.
Step 2: Choose the Right Notch
Select the notch that best suits your situation. Consider the tree’s size, type, and lean, as well as your specific felling goals, such as maximizing wood yield or ensuring a controlled fall in a precise direction.
Step 3: Make the Notch Cuts
Using a chainsaw, make the appropriate cuts for your chosen notch. Begin with the horizontal cut, followed by the angled cut to remove the wedge. Ensure your cuts are clean and precise, with no overcuts that could compromise the hinge’s integrity.
Step 4: Create the Back Cut
The back cut is made on the opposite side of the notch. This cut releases the tree, allowing it to fall. It should be made slightly above the base of the notch to maintain the hinge, which guides the tree’s fall.
- Back Cut: Maintain a steady, level cut. Stop cutting as soon as the tree begins to fall to preserve the hinge.
Step 5: Retreat to Safety
As soon as the tree begins to fall, use your pre-planned escape route to move to a safe distance. Never turn your back on the falling tree until you are at a safe distance.

Safety Tips for Tree Felling
Tree felling is inherently risky, so safety must always be a priority. Here are some essential safety tips to keep in mind:
- Protective Gear: Always wear appropriate safety gear, including a helmet, eye protection, gloves, and sturdy boots.
- Clear Area: Ensure the area around the tree is clear of people, animals, and obstacles.
- Chainsaw Safety: Use a well-maintained chainsaw and follow all safety guidelines.
- Teamwork: If possible, work with a partner who can alert you to any potential hazards.
