How to Climb Trees Safely for Cutting (Pro Arborist Tips)

Ever looked up at a towering tree and thought, “I need to get up there… with a chainsaw?” Sounds a bit crazy, right? But for arborists and tree care professionals, it’s a daily reality. Climbing trees safely for cutting isn’t just about strapping on a harness and hoping for the best. It’s a calculated dance between skill, knowledge, and respect for the power of gravity (and that roaring chainsaw!). So, how do you actually do it? Let’s dive into the world of professional tree climbing and cutting, where safety is paramount and every move matters.

The Ascent: Preparing for Safe Tree Climbing

Before you even think about touching a chainsaw, the prep work is critical. This isn’t a “wing it” kind of situation. Think of it like preparing for a high-stakes surgery, but instead of a scalpel, you’re wielding a powerful cutting tool dozens of feet in the air.

Gear Up: Essential Equipment for Arborists

First, let’s talk gear. This isn’t your grandpa’s ladder and a pair of gardening gloves. We’re talking specialized equipment designed to keep you safe and mobile in the canopy.

• Harness: This is your lifeline. A good arborist harness distributes weight comfortably and provides multiple attachment points. Look for models with adjustable leg loops and a padded back for all-day comfort. My personal favorite is the Buckingham Ergovation harness. I’ve used it for years, and it’s never let me down. I’ve found that a properly fitted harness can reduce fatigue and increase mobility.
• Climbing Line: A strong, flexible rope is crucial. Arborist climbing lines are typically made of a low-stretch material like polyester or nylon. The diameter and length will depend on the size of the trees you’re working on. I always inspect my climbing line before each climb, checking for any signs of wear or damage. A frayed rope is a no-go.
• Flipline/Lanyard: This shorter rope, often with a steel core, is used for positioning yourself once you’re in the tree. It allows you to lean away from the trunk and have both hands free for cutting. I prefer a flipline with a micro-adjuster, which allows me to make small adjustments to my position with ease.
• Helmet: A sturdy helmet is non-negotiable. Look for one that meets ANSI Z89.1 standards and provides impact protection. A face shield and ear protection are also essential. I can’t tell you how many times my helmet has saved me from falling branches.
• Chainsaw: Obviously, you’ll need a chainsaw. But not just any chainsaw will do. A lightweight, top-handled saw is ideal for tree work. Look for features like a chain brake and vibration dampening. I typically use a Stihl MS 201 T for most of my climbing work. It’s lightweight, powerful, and reliable.
• First Aid Kit: Accidents happen. A well-stocked first aid kit is essential for treating minor injuries on the spot. Make sure it includes items like bandages, antiseptic wipes, and pain relievers. I once had a close call when a small branch poked me in the eye. Luckily, I had eye wash in my kit and was able to flush it out immediately.
• Steel Core Lanyard: A steel core lanyard is a short length of rope or cable with a steel core, used for positioning and securing oneself in a tree while climbing or performing tree work. It provides a secure and stable connection point, allowing arborists to work hands-free.

Assessing the Tree: Reading the Wood

Before you even think about climbing, you need to assess the tree. This is where your knowledge of tree species, growth habits, and potential hazards comes into play.

• Species Identification: Knowing the species of tree you’re working on is crucial. Different species have different wood densities, growth patterns, and susceptibility to diseases. For example, oak is a dense, strong wood, while poplar is softer and more prone to decay. I always carry a tree identification guide with me in the field.
• Structural Integrity: Look for signs of decay, cracks, or other structural weaknesses. Pay close attention to the trunk, branches, and root system. A tree with significant decay may be unstable and unsafe to climb. I use a resistograph to assess the internal condition of trees. It’s a non-destructive tool that measures the resistance of the wood to a small drill bit.
• Hazard Identification: Identify any potential hazards, such as dead branches (widowmakers), power lines, or nearby structures. Plan your climb to avoid these hazards. I once had to abort a climb because I spotted a wasp nest hidden in a branch. It’s always better to be safe than sorry.
• Weather Conditions: Never climb in high winds, heavy rain, or lightning. These conditions can make climbing extremely dangerous. Wind can cause branches to sway unpredictably, while rain can make surfaces slippery. I always check the weather forecast before heading out to a job site.

Planning Your Ascent: Charting the Course

With your gear checked and the tree assessed, it’s time to plan your ascent. This involves choosing a climbing route, setting your climbing line, and establishing a secure tie-in point.

• Choosing a Climbing Route: Look for a route that is free of obstructions and provides a clear path to your work area. Avoid climbing directly under dead branches or power lines. I like to use a technique called “rope walking,” where I use my climbing line to ascend the tree in a series of controlled steps.
• Setting Your Climbing Line: There are several methods for setting a climbing line, including using a throw line, a slingshot, or a climbing pole. The goal is to get your climbing line over a strong, healthy branch that is high enough to provide a good working position. I prefer to use a throw line with a weighted throw bag. It’s accurate and efficient.
• Establishing a Tie-In Point: Once your climbing line is set, you need to establish a secure tie-in point. This is where you attach your climbing line to your harness. Use a reliable knot, such as a Blake’s hitch or a Prusik hitch. I always double-check my tie-in point before starting my climb.

In the Canopy: Safe Cutting Techniques

Once you’re safely positioned in the tree, it’s time to start cutting. This is where your chainsaw skills and knowledge of tree anatomy come into play.

Chainsaw Safety: Respect the Power

Chainsaws are powerful tools, and they demand respect. Always follow these safety guidelines when operating a chainsaw in a tree.

• Two-Handed Grip: Always maintain a firm, two-handed grip on the chainsaw. This will help you control the saw and prevent kickback. I’ve seen too many accidents caused by people using a chainsaw with one hand.
• Proper Stance: Maintain a stable stance and keep your feet firmly planted. Avoid reaching or overextending yourself. I use my flipline to position myself so that I can reach the branch I’m cutting without having to lean too far.
• Chain Brake: Use the chain brake whenever you’re not actively cutting. This will prevent the chain from spinning and reduce the risk of accidental cuts. I always engage the chain brake when I’m moving between branches.
• Cutting Techniques: Use proper cutting techniques to avoid kickback and other hazards. This includes making a notch cut before felling a branch and avoiding cutting with the tip of the saw. I’ve found that a sharp chain is essential for safe cutting. A dull chain is more likely to kick back.
• Personal Protective Equipment (PPE): Always wear appropriate PPE, including a helmet, eye protection, ear protection, and cut-resistant chaps. I also wear gloves to protect my hands from cuts and abrasions.

Branch Removal: A Controlled Descent

Removing branches safely requires careful planning and execution. The goal is to lower the branches to the ground in a controlled manner, without damaging property or injuring anyone.

• Planning the Cut: Before making any cuts, assess the weight and balance of the branch. Determine the best place to make the cut and how the branch will fall. I like to use a technique called “piecing out,” where I cut the branch into smaller, more manageable pieces.
• Making the Cut: Use a three-cut method to remove the branch. First, make an undercut to prevent the bark from tearing. Then, make a top cut that meets the undercut. Finally, make a back cut to sever the branch completely. I always use a rope to control the descent of the branch.
• Lowering the Branch: Use a rope and pulley system to lower the branch to the ground in a controlled manner. This will prevent the branch from falling freely and potentially causing damage or injury. I often use a port-a-wrap to control the speed of the descent.
• Communication: Communicate clearly with your ground crew to ensure that everyone is aware of what you’re doing. Use hand signals or a two-way radio to communicate effectively. I always have a spotter on the ground to make sure that no one is in the path of the falling branch.

Tree Felling: The Art of Controlled Falling

Tree felling is the most dangerous aspect of tree work. It requires a thorough understanding of tree anatomy, physics, and safety procedures.

• Assessing the Tree: Before felling a tree, assess its size, lean, and any potential hazards. Determine the best direction to fell the tree and clear the area of any obstacles. I use a clinometer to measure the lean of the tree.
• Making the Notch Cut: The notch cut determines the direction of the fall. It should be made on the side of the tree that you want it to fall towards. The notch should be about one-third of the tree’s diameter. I always make sure that the notch is clean and precise.
• Making the Back Cut: The back cut is made on the opposite side of the tree from the notch cut. It should be made slightly above the bottom of the notch. Leave a hinge of wood between the back cut and the notch cut to control the fall of the tree. I use wedges to help guide the fall of the tree.
• Felling the Tree: Once the back cut is complete, the tree will begin to fall. Move away from the tree quickly and watch for any falling branches. I always have an escape route planned in advance.
• Statistics on Tree Felling Accidents: According to the Tree Care Industry Association (TCIA), tree felling is one of the most dangerous jobs in the United States. In 2020, there were 118 tree care fatalities in the U.S., with a significant portion attributed to improper felling techniques. The most common causes of accidents include being struck by the falling tree, falling from the tree, and chainsaw-related injuries. These statistics highlight the critical importance of proper training, adherence to safety protocols, and continuous risk assessment in tree felling operations.

Wood Processing: From Tree to Usable Material

Once the tree is down, the work isn’t over. The next step is to process the wood into usable material. This can involve cutting it into firewood, milling it into lumber, or chipping it for mulch.

Firewood Preparation: The Warmth of Hard Work

Cutting firewood is a common way to utilize felled trees. It’s a physically demanding task, but it can be a rewarding way to heat your home or provide fuel for outdoor activities.

• Choosing the Right Wood: Different types of wood have different burning properties. Hardwoods like oak, maple, and ash burn hotter and longer than softwoods like pine and fir. I prefer to burn oak because it produces a lot of heat and doesn’t create much smoke.
• Cutting the Wood: Cut the wood into lengths that are appropriate for your fireplace or wood stove. A typical length is 16 inches. I use a chainsaw to cut the wood into rounds and then split it with a splitting axe or a hydraulic log splitter.
• Splitting the Wood: Splitting the wood makes it easier to dry and burn. Use a splitting axe or a hydraulic log splitter to split the rounds into smaller pieces. I always wear safety glasses when splitting wood to protect my eyes from flying chips.
• Seasoning the Wood: Seasoning the wood involves drying it for several months. This reduces the moisture content and makes it burn more efficiently. Stack the wood in a sunny, well-ventilated area. I typically season my firewood for at least six months.

Milling Lumber: Turning Trees into Timber

Milling lumber is a more complex process than cutting firewood, but it can be a great way to produce high-quality building materials.

• Choosing the Right Mill: There are several types of sawmills available, including portable sawmills, band sawmills, and circular sawmills. The best type of mill for you will depend on the size and type of trees you’re milling, as well as your budget. I use a portable sawmill because it allows me to mill lumber on site.
• Preparing the Log: Before milling the log, remove any bark or debris. This will help to prolong the life of your saw blades. I use a debarker to remove the bark.
• Milling the Lumber: Use the sawmill to cut the log into boards of the desired thickness. Follow the grain of the wood to maximize the strength and stability of the lumber. I always wear safety glasses and ear protection when milling lumber.
• Drying the Lumber: Drying the lumber is essential to prevent warping and cracking. Stack the lumber in a well-ventilated area and allow it to air dry for several months. I use a moisture meter to check the moisture content of the lumber.

Chipping Wood: Recycling Tree Waste

Chipping wood is a great way to recycle tree waste and create mulch for landscaping or gardening.

• Choosing the Right Chipper: There are several types of wood chippers available, including drum chippers, disc chippers, and hydraulic chippers. The best type of chipper for you will depend on the size and type of branches you’re chipping, as well as your budget. I use a hydraulic chipper because it can handle large branches with ease.
• Operating the Chipper: Follow the manufacturer’s instructions for operating the chipper safely. Always wear safety glasses, ear protection, and gloves. Avoid feeding branches that are too large or too small into the chipper. I always have a spotter to help me feed the branches into the chipper.
• Using the Mulch: The mulch can be used for a variety of purposes, including landscaping, gardening, and erosion control. It can also be used as a fuel source for biomass power plants. I use the mulch in my garden to suppress weeds and retain moisture.

Unique Insights: The Arborist’s Perspective

Having spent years in the trees, I’ve learned a few things that you won’t find in textbooks. Here are some unique insights that I’ve gained from my experiences:

The Importance of Intuition

While knowledge and skill are essential, intuition also plays a role in safe tree climbing and cutting. Sometimes, you just have a feeling that something isn’t right. Trust your instincts and don’t hesitate to abort a climb if you feel uncomfortable. I once had a feeling that a tree was unstable, even though I couldn’t see any obvious signs of decay. I decided not to climb it, and the next day, it fell down in a storm.

The Value of Mentorship

Learning from experienced arborists is invaluable. Find a mentor who can teach you the ropes and share their knowledge and expertise. I was fortunate to have a great mentor who taught me everything I know about tree climbing and cutting. He not only taught me the technical skills, but he also instilled in me a deep respect for trees and a commitment to safety.
