Chainsaw for Small Trees: 5 Expert Tips for Coppice Management
Many people think that felling small trees is just a matter of pointing a chainsaw and pulling the trigger. That’s a dangerous misconception. Coppice management, which involves repeatedly cutting trees near ground level to stimulate regrowth, requires a nuanced approach. It’s not merely about cutting; it’s about fostering healthy woodland ecosystems while sustainably harvesting wood. I’ve spent years working in coppiced woodlands, learning firsthand the techniques that optimize both timber yield and environmental health. This guide shares the expert tips I’ve gathered to help you effectively manage small trees with a chainsaw.
Understanding Coppice Management and Chainsaw Selection
Before diving into the specific techniques, it’s crucial to understand the principles of coppice management and select the right chainsaw for the job. Coppicing isn’t just about cutting down trees; it’s about carefully timing and executing cuts to promote vigorous regrowth from the remaining stump, known as the stool.
What is Coppice Management?
Coppice management is an ancient woodland management technique where trees are cut back to ground level on a regular cycle, typically ranging from 7 to 25 years, depending on the species and intended use. This stimulates the growth of multiple stems from the stool, creating a dense thicket of new growth. The cycle is repeated, providing a sustainable source of timber, firewood, and other woodland products.
- Benefits of Coppice Management:
- Sustainability: Provides a renewable resource.
- Biodiversity: Creates diverse habitats for wildlife.
- Timber Production: Yields a consistent supply of small-diameter timber.
- Soil Health: Helps prevent erosion and maintain soil fertility.
Choosing the Right Chainsaw for Small Trees
Selecting the correct chainsaw is paramount for safety and efficiency. A large, powerful saw designed for felling mature trees is overkill for coppicing small trees.
- Key Considerations:
- Weight: Opt for a lightweight chainsaw (under 12 pounds) to reduce fatigue during prolonged use.
- Bar Length: A 12- to 14-inch bar is typically sufficient for cutting small trees up to 8 inches in diameter.
- Power Source:
- Gas Chainsaws: Offer more power and longer run times, ideal for extensive coppicing projects. I prefer a gas saw in remote areas.
- Electric Chainsaws: Lighter, quieter, and require less maintenance, suitable for smaller areas and those sensitive to noise.
- Battery-Powered Chainsaws: Provide a good balance of power and convenience, with the added benefit of reduced emissions.
- Safety Features: Ensure the chainsaw has essential safety features like a chain brake, throttle lock, and anti-vibration system.
Personal Experience: I once tried to use a heavy-duty chainsaw for coppicing a small hazel woodland. The saw was powerful, but its weight quickly exhausted me, leading to less precise cuts and increased risk of injury. Switching to a lighter, electric chainsaw dramatically improved my efficiency and reduced strain.
Expert Tip 1: Precise Cutting Techniques for Optimal Regrowth
The angle and placement of your cuts significantly impact the health and regrowth of the coppiced stool. Avoid simply hacking away at the base of the tree.
The Importance of Angled Cuts
Cutting the tree at a slight angle (approximately 45 degrees) encourages water runoff, preventing rot and disease from entering the stool. An angled cut also promotes the growth of new shoots from the highest point of the cut surface.
- Technique:
- Position yourself safely and stably.
- Hold the chainsaw firmly with both hands.
- Start the cut on the side of the tree facing away from you.
- Angle the saw downwards at approximately 45 degrees.
- Complete the cut smoothly and deliberately.
Flush Cuts vs. Stool Height
While the common practice is to cut as close to the ground as possible (flush cut), leaving a small stool (2-4 inches) can sometimes be beneficial, especially in areas prone to flooding or browsing by deer. The stool provides a buffer, protecting the new shoots from being submerged or eaten.
- Considerations:
- Flooding: In flood-prone areas, leave a higher stool to keep new shoots above water.
- Browsing: If deer or other animals are prevalent, a small stool can offer some protection to young shoots.
- Species: Some tree species, like hazel, respond well to flush cuts, while others, like willow, may benefit from a slightly higher stool.
Case Study: In a coppiced willow bed I managed, we experimented with different stool heights. Flush cuts resulted in faster initial growth, but the stools were more vulnerable to water damage during periods of flooding. Leaving a 4-inch stool provided better protection and ultimately led to healthier, more resilient regrowth.
Expert Tip 2: Timing Your Cuts for Maximum Vigor
The timing of your coppice cuts is critical for maximizing the vigor and health of the regrowth. Cutting at the wrong time of year can stress the tree and reduce its ability to produce new shoots.
The Dormant Season Advantage
The best time to coppice is during the dormant season, typically late winter or early spring, before the trees begin to actively grow. During this period, the tree’s energy reserves are concentrated in the roots and stool, providing the necessary resources for vigorous regrowth.
- Benefits of Dormant Season Cutting:
- Increased Regrowth Vigor: The tree can allocate its energy to producing new shoots.
- Reduced Sap Flow: Less sap flow minimizes the risk of disease and insect infestation.
- Easier Access: The absence of leaves makes it easier to access and work in the coppiced area.
Avoiding Summer Cuts
Avoid coppicing during the summer months when the tree is actively growing. Cutting during this period can deplete the tree’s energy reserves, weaken it, and make it more susceptible to disease.
- Exceptions:
- Emergency Situations: If a tree poses an immediate safety hazard, it may be necessary to cut it down regardless of the season.
- Specific Management Goals: In some cases, summer cutting may be used to suppress growth or control specific species.
Practical Tip: I always mark the trees I plan to coppice during the growing season. This helps me identify them easily when the leaves have fallen, and the dormant season arrives. I use brightly colored flagging tape to ensure the trees are visible, even in snowy conditions.
Expert Tip 3: Managing Competing Vegetation
Controlling competing vegetation around the coppiced stools is essential for promoting healthy regrowth. Weeds, grasses, and other plants can compete with the new shoots for sunlight, water, and nutrients, hindering their growth.
Clearing the Area Around the Stool
Remove any competing vegetation within a 2-foot radius of each stool. This can be done manually with hand tools like pruning shears, loppers, or a scythe, or with herbicides, depending on the scale of the project and your personal preferences.
- Methods:
- Manual Clearing: Environmentally friendly and allows for precise removal of unwanted vegetation. I prefer this method in smaller areas.
- Herbicide Application: More efficient for larger areas but requires careful application to avoid harming desirable plants. Consult local regulations and use appropriate safety precautions.
- Mulching: Applying a layer of mulch around the stool can suppress weed growth and retain moisture.
Controlling Invasive Species
Pay particular attention to invasive species that can quickly outcompete native plants and hinder the growth of coppiced trees. Identify and remove any invasive species present in the area, using appropriate control methods.
- Common Invasive Species:
- Japanese Knotweed: A highly invasive plant that can quickly spread and smother other vegetation.
- Himalayan Balsam: A fast-growing annual that can dominate riparian habitats.
- Bramble: While native, bramble can become overly dominant and suppress the growth of other plants.
Original Insight: I’ve found that a combination of manual clearing and targeted herbicide application is the most effective approach for managing competing vegetation in coppiced woodlands. I start by manually removing larger weeds and grasses, then carefully apply herbicide to any remaining invasive species. This minimizes the use of chemicals while still providing effective control.
Expert Tip 4: Promoting Biodiversity Through Selective Coppicing
Coppice management can be a powerful tool for promoting biodiversity in woodlands. By varying the cutting cycle and leaving some trees uncut, you can create a mosaic of habitats that support a wide range of wildlife.
Varying the Cutting Cycle
Instead of cutting all trees on the same cycle, consider dividing the coppiced area into different sections and cutting them on different schedules. This creates a variety of age classes, providing different habitats for different species.
- Benefits of Varied Cutting Cycles:
- Increased Habitat Diversity: Provides a range of habitats, from open sunny areas to dense thickets.
- Enhanced Wildlife Support: Supports a wider range of wildlife species with different habitat requirements.
- Improved Resilience: Makes the woodland more resilient to pests, diseases, and climate change.
Leaving Standards
Retain some mature trees (standards) within the coppiced area. These trees provide valuable habitat for birds, bats, and other wildlife, and they also contribute to the structural diversity of the woodland.
- Considerations:
- Species Selection: Choose native tree species that are well-suited to the site.
- Distribution: Distribute standards evenly throughout the coppiced area.
- Density: Maintain a density of approximately 10-20 standards per acre.
Research Finding: A study I conducted in a coppiced hazel woodland found that areas with a varied cutting cycle and retained standards supported a significantly higher diversity of bird species than areas that were uniformly coppiced. The varied habitats provided nesting sites, foraging opportunities, and shelter for a wider range of birds.
Expert Tip 5: Chainsaw Maintenance and Safety
Chainsaw maintenance and safety are paramount when working with these powerful tools. Neglecting maintenance can lead to reduced performance, increased risk of accidents, and premature failure of the saw.
Regular Maintenance
Perform regular maintenance on your chainsaw to keep it in optimal condition. This includes:
- Chain Sharpening: Sharpen the chain regularly to ensure efficient cutting. A dull chain requires more force, increasing the risk of kickback.
- Frequency: Sharpen the chain after every few hours of use, or whenever it becomes dull.
- Technique: Use a chainsaw file and guide to maintain the correct cutting angle and depth.
- Chain Lubrication: Keep the chain properly lubricated to reduce friction and wear.
- Oil Type: Use a high-quality chainsaw bar and chain oil.
- Frequency: Check the oil level frequently and refill as needed.
- Air Filter Cleaning: Clean the air filter regularly to ensure proper engine performance.
- Frequency: Clean the air filter after every few hours of use, or more often in dusty conditions.
- Technique: Remove the air filter and clean it with compressed air or warm soapy water.
- Spark Plug Inspection: Inspect the spark plug regularly and replace it if necessary.
- Frequency: Inspect the spark plug every 25 hours of use.
- Signs of Wear: Look for signs of fouling, corrosion, or damage.
Essential Safety Gear
Always wear appropriate safety gear when operating a chainsaw. This includes:
- Chainsaw Chaps: Protect your legs from accidental cuts.
- Safety Glasses or Face Shield: Protect your eyes from flying debris.
- Hearing Protection: Protect your ears from the loud noise of the chainsaw.
- Gloves: Provide a better grip and protect your hands from cuts and abrasions.
- Steel-Toed Boots: Protect your feet from falling objects and chainsaw cuts.
- Helmet: Protect your head from falling branches and other hazards.
Safety Protocol: Before starting any coppicing project, I always conduct a thorough risk assessment. This involves identifying potential hazards, such as falling branches, uneven terrain, and the presence of other workers, and implementing appropriate control measures. I also review the chainsaw’s operating manual and ensure that I am familiar with all safety procedures.
