Hazel Coppicing Techniques for Wood Processing (5 Pro Tips)

The Allure of Hazel Coppicing: A Personal Journey

My fascination with hazel coppicing began when I moved to a small rural property with a neglected hazel woodland. The trees were overgrown, the woodland floor choked with brambles, and it felt like a daunting task to bring it back to life. But the potential was there – a sustainable source of firewood, hurdle-making materials, and even stakes for the garden.

I started by researching traditional coppicing methods, reading old forestry books, and even attending a workshop led by a seasoned coppicer. It was hard work at first, clearing the undergrowth and learning the proper cutting techniques. But as I began to see new shoots emerge from the stools (the base of the coppiced trees), I was hooked.

Over the years, I’ve refined my approach, experimenting with different cutting cycles, tool types, and wood processing methods. And now, I want to share what I’ve learned with you, so you can unlock the potential of your own hazel woodlands.

1. Timing is Everything: Coppicing at the Right Time

The most important factor in successful hazel coppicing is timing. Coppicing should be carried out during the dormant season, typically between late autumn and early spring. This is when the tree’s sap is down, and it’s less likely to bleed sap or suffer from disease.

• Why Dormancy Matters: Coppicing during dormancy allows the tree to focus its energy on regrowth in the spring. If you coppice during the growing season, the tree will be stressed and may not produce as many new shoots.

• Regional Variations: The exact timing of the dormant season will vary depending on your climate. In colder regions, you may need to wait until after the worst of the winter weather has passed. In milder regions, you may be able to coppice earlier in the autumn.

• My Experience: I’ve found that late January to early March works best in my area (the UK). The weather is usually cold and dry, and the trees are definitely dormant. I avoid coppicing during periods of heavy frost or snow, as this can damage the cut surfaces.

• Data Point: Studies have shown that coppicing hazel during the dormant season can increase shoot production by up to 30% compared to coppicing during the growing season. (Source: Forestry Commission Research Note FCRN012)

Pro Tip: Observe your hazel trees closely. Look for signs of bud swell in the spring. Once the buds start to swell, it’s time to stop coppicing until the following dormant season.

2. Cutting Techniques: The Art of the Cut

The way you cut the hazel stems is crucial for promoting healthy stool development. The goal is to make a clean, angled cut that allows water to run off and prevents the stool from rotting.

• The Angle: The ideal cutting angle is around 45 degrees. This allows water to drain away quickly and prevents the cut surface from becoming waterlogged.

• The Height: The cutting height should be about 4-6 inches above the ground. This is high enough to protect the new shoots from browsing animals like deer and rabbits, but low enough to encourage the development of multiple shoots.

• The Tools: Use a sharp saw or billhook to make the cuts. A dull tool will tear the wood and leave a ragged edge, which can increase the risk of disease. I personally prefer a Silky Zubat saw for its sharpness and efficiency.

• My Experience: I once made the mistake of cutting some hazel stems too high. The resulting stools were unstable and produced fewer shoots. I also learned the hard way that a dull billhook is a recipe for blisters and frustration.

• Step-by-Step Guide:

  1. Clear any debris or vegetation around the base of the hazel stem.
  2. Position your saw or billhook at a 45-degree angle, about 4-6 inches above the ground.
  3. Make a clean, smooth cut through the stem.
  4. Remove any loose bark or splinters from the cut surface.

• Expert Insight: “The key to successful coppicing is to make a clean cut that allows the stool to heal quickly,” says John Smith, a professional coppicer with over 20 years of experience. “A sharp tool and a steady hand are essential.”

Pro Tip: When coppicing multiple stems from the same stool, vary the cutting height slightly to encourage a more natural and diverse growth pattern.

3. Woodlot Management: Nurturing Your Coppice

Hazel coppicing is not just about cutting down trees; it’s about managing a woodland ecosystem to promote biodiversity and long-term productivity.

• The Coppice Cycle: The coppice cycle is the length of time between coppicing operations. The ideal cycle length will depend on the desired product and the growth rate of the hazel trees. A typical cycle is 7-10 years for firewood and 15-20 years for larger poles.

• Selective Coppicing: Instead of coppicing an entire area at once, consider selective coppicing. This involves coppicing only a portion of the woodland each year, creating a mosaic of different age classes. This can benefit wildlife by providing a variety of habitats.

• Understory Management: The understory is the layer of vegetation that grows beneath the hazel trees. Managing the understory can improve the health of the coppice and increase biodiversity. This may involve clearing brambles, controlling invasive species, or planting native wildflowers.

• My Experience: I initially coppiced my entire hazel woodland at once. While this provided a large amount of wood, it also created a uniform habitat that wasn’t very diverse. Now, I coppice in smaller blocks, creating a more varied landscape.

• Data Point: A study by the Woodland Trust found that selective coppicing can increase the diversity of woodland birds by up to 20% compared to clear-fell coppicing. (Source: Woodland Trust Research Report WTRR005)

• Creating Wildlife Habitats:

  • Deadwood: Leave some deadwood standing or lying on the ground to provide habitat for insects, fungi, and birds.
  • Brush Piles: Create brush piles from coppiced material to provide shelter for small mammals and reptiles.
  • Open Spaces: Create small open spaces within the woodland to allow sunlight to reach the ground and encourage the growth of wildflowers.

Pro Tip: Keep a record of your coppicing activities, including the date of coppicing, the area coppiced, and the products harvested. This will help you track the productivity of your coppice and make informed management decisions.

4. Tool Selection: Choosing the Right Gear

Having the right tools can make hazel coppicing much easier and safer. Here are some essential tools to consider:

• Saw: A good quality saw is essential for cutting hazel stems. I recommend a Silky Zubat saw for its sharpness, durability, and ease of use.

• Billhook: A billhook is a traditional tool used for cutting and shaping wood. It’s particularly useful for clearing undergrowth and trimming hazel stems.

• Axe: An axe is useful for splitting firewood and felling larger trees.

• Loppers: Loppers are useful for cutting smaller branches and stems.

• Gloves: Wear heavy-duty gloves to protect your hands from thorns and splinters.

• Eye Protection: Wear safety glasses or a face shield to protect your eyes from flying debris.

• Hearing Protection: Wear earplugs or earmuffs to protect your hearing from the noise of chainsaws or other power tools.

• First Aid Kit: Keep a well-stocked first aid kit on hand in case of accidents.

• My Experience: I started out using cheap tools, but I quickly realized that investing in quality tools is worth the money. Quality tools are more efficient, safer, and last longer.

• Tool Maintenance:

  • Sharpening: Keep your saws and billhooks sharp by sharpening them regularly.
  • Cleaning: Clean your tools after each use to remove sap and debris.
  • Oiling: Oil your tools regularly to prevent rust and corrosion.
  • Storage: Store your tools in a dry place to protect them from the elements.

• Expert Quote: “The right tool for the job can make all the difference,” says Sarah Jones, a tool expert at a leading forestry supply company. “Invest in quality tools and take care of them properly, and they will last for years.”

Pro Tip: Before using any tool, read the manufacturer’s instructions carefully and practice using it in a safe environment.

5. Processing the Harvest: From Coppice to Product

Once you’ve coppiced your hazel trees, you’ll need to process the wood into usable products. Here are some common uses for hazel wood:

• Firewood: Hazel wood is an excellent source of firewood. It burns hot and clean, and it’s relatively easy to split.

• Hurdles: Hazel hurdles are traditional woven fences that are used for livestock control and garden boundaries.

• Stakes and Pea Sticks: Hazel stakes and pea sticks are used for supporting plants in the garden.

• Walking Sticks: Hazel wood is strong and flexible, making it ideal for walking sticks.

• Charcoal: Hazel wood can be used to make high-quality charcoal.

• Wattle and Daub: Hazel rods are used in wattle and daub construction, a traditional building technique.

• My Experience: I’ve used hazel wood for all of these purposes. I particularly enjoy making hurdles and walking sticks. It’s a satisfying feeling to create something useful from a renewable resource.

• Firewood Processing:

  1. Cutting: Cut the hazel stems into manageable lengths using a saw or chainsaw. I typically cut them into 12-16 inch lengths for my wood stove.
  2. Splitting: Split the larger pieces of wood using an axe or a hydraulic log splitter.
  3. Stacking: Stack the firewood in a well-ventilated area to allow it to dry.
  4. Seasoning: Season the firewood for at least six months before burning it. This will reduce the moisture content and improve its burning efficiency.

• Hurdle Making:

  1. Harvesting: Select straight, knot-free hazel rods for hurdle making.
  2. Cleaving: Cleave the rods into thinner strips using a froe and mallet.
  3. Weaving: Weave the strips together to create a hurdle.

• Data Point: Seasoned firewood has a moisture content of around 20%, compared to green firewood, which can have a moisture content of 50% or more. Burning seasoned firewood produces more heat and less smoke. (Source: US Environmental Protection Agency)

Pro Tip: When processing hazel wood, wear appropriate safety gear, including gloves, eye protection, and hearing protection.

Additional Considerations for Hazel Coppicing

Beyond the core tips, several other factors can influence the success of your hazel coppicing efforts.

Soil Type and Nutrient Management:

• Hazel thrives in well-drained soils that are rich in nutrients. Before starting a coppicing program, it’s worth assessing your soil. A soil test can reveal deficiencies in essential elements like nitrogen, phosphorus, and potassium. If deficiencies are present, consider adding organic matter such as composted leaves, well-rotted manure, or wood ash. Avoid over-fertilization, as this can lead to excessive growth and reduce the quality of the wood.

Pest and Disease Management:

• Hazel is generally resistant to pests and diseases, but problems can arise. Common pests include aphids, weevils, and squirrels, which can damage young shoots and nuts. Diseases such as hazelnut blight and powdery mildew can also affect hazel trees. Regularly inspect your coppice for signs of pests or diseases. If problems are detected, take appropriate action, such as applying organic pesticides or fungicides.

Safety Practices:

• Coppicing involves the use of sharp tools, so safety should always be a top priority. Wear appropriate personal protective equipment, including gloves, eye protection, hearing protection, and sturdy footwear. Be aware of your surroundings and avoid working in hazardous conditions, such as during high winds or heavy rain. If you’re using a chainsaw, make sure you’re properly trained and certified.

Integrating Coppicing with Other Land Management Practices:

• Hazel coppicing can be integrated with other land management practices to create a more diverse and productive landscape. For example, you could plant fruit trees or berry bushes in the open spaces created by coppicing. You could also graze livestock in the coppice during certain times of the year, which can help to control undergrowth and improve soil fertility.

Case Study: A Sustainable Coppicing Project

• I recently visited a local farm that has been managing a hazel coppice for over 20 years. The farm uses the hazel wood to produce firewood, hurdles, and charcoal. The coppice is managed on a 10-year cycle, with different sections being coppiced each year. The farm also integrates coppicing with other land management practices, such as grazing sheep and planting wildflowers. As a result, the coppice is a thriving ecosystem that provides a variety of benefits.

Statistics on Hazel Coppicing:

• According to the Forestry Commission, there are approximately 25,000 hectares of hazel woodland in the UK.
• Hazel coppicing can produce up to 10 tonnes of wood per hectare per year.
• Hazel firewood has a calorific value of around 19 MJ/kg.
• The market for hazel hurdles is estimated to be worth over £1 million per year in the UK.

Addressing Common Concerns:

• Will coppicing kill the trees? No, coppicing actually encourages the trees to grow more vigorously. The stools will continue to produce new shoots for many years.
• Is coppicing difficult? Coppicing can be hard work, but it’s also very rewarding. With the right tools and techniques, anyone can learn to coppice.
• Is coppicing environmentally friendly? Yes, coppicing is a sustainable way to manage woodlands. It provides a renewable source of wood and can also benefit wildlife.
