Coppice Trees for Firewood: 5 Expert Tips for Optimal Harvest

Understanding Coppicing: More Than Just Cutting Trees

Coppicing is a traditional woodland management technique where trees are cut down to near ground level, stimulating new growth from the stump or root system. This results in multiple stems growing from the cut stool (the base of the tree), which can then be harvested on a rotation.

Why Coppice for Firewood?

• Sustainability: Coppicing allows for a continuous yield of wood without killing the tree, making it a sustainable practice.
• Biodiversity: Coppiced woodlands often have a diverse range of habitats, benefiting wildlife.
• Firewood Production: Coppicing can provide a reliable source of firewood, especially when managed correctly.
• Woodland Health: Regular coppicing can improve the overall health and vigor of your woodland.

1. Select the Right Trees: Choosing the Champions of Regeneration

The success of coppicing hinges on selecting tree species that readily regenerate from their stumps. Not all trees are created equal in this regard. Some species sprout vigorously, while others are less reliable.

Champion Coppicers:

• Hazel (Corylus avellana): This is a top choice for coppicing. Hazel is known for its rapid regrowth and produces excellent firewood. Its flexible stems are also useful for crafts and building.
• Sweet Chestnut (Castanea sativa): Another excellent coppicing species, Sweet Chestnut, grows quickly and provides durable, rot-resistant firewood. It’s also a valuable timber tree.
• Willow (Salix spp.): Willow is incredibly fast-growing and can be coppiced on very short rotations. It’s ideal for biomass production and can also be used for weaving and biofuel.
• Ash (Fraxinus excelsior): While Ash faces challenges from Ash Dieback disease, healthy Ash trees coppice well and provide high-quality firewood.
• Hornbeam (Carpinus betulus): A dense, slow-growing hardwood, Hornbeam coppices reliably and produces excellent firewood with a high heat output.
• Birch (Betula pendula/pubescens): Birch coppices well, but the wood is not as durable as other species. It’s a good choice for kindling and quick-burning firewood.
• Maple (Acer campestre): Field Maple coppices well and provides good firewood, although it may not grow as quickly as some other species.
• Poplar (Populus spp.): Poplar is a fast-growing species that coppices readily, making it suitable for biomass production.
• Oak (Quercus robur/petraea): While Oak can be coppiced, it is a slower process than with species like Hazel or Sweet Chestnut. The resulting wood is very high quality and long-burning.

Species to Avoid (or Use with Caution):

• Conifers (Pine, Fir, Spruce): Conifers generally do not coppice well. They lack the dormant buds needed to sprout from the stump.
• Beech (Fagus sylvatica): Beech can coppice, but it’s less reliable than other species and can be slow to regenerate.
• Cherry (Prunus avium): Wild Cherry can coppice, but it’s often more successful when allowed to grow into a standard tree.

My Personal Experience:

I’ve had the most success with Hazel and Sweet Chestnut in my own woodland. The Hazel provides a quick return, and the Chestnut offers more substantial firewood. I’ve also experimented with Willow for short-rotation coppicing, which has been surprisingly productive.

Data-Backed Insight:

A study by the Forestry Commission found that Hazel coppice can yield up to 10 tonnes of dry wood per hectare every 7-10 years, while Sweet Chestnut can yield up to 15 tonnes per hectare over a similar period. This highlights the productivity of these species when coppiced.

Actionable Tip:

Before you start coppicing, take a walk through your woodland and identify the dominant species. If you have a mix of species, prioritize coppicing those known for their regenerative abilities. If you’re planting new trees, choose coppicing-friendly species to ensure a sustainable firewood supply in the future.

2. Time Your Cuts Strategically: The Season of the Saw

The timing of your coppice cuts is crucial for the health and vigor of the regrowth. Cutting at the right time of year can significantly impact the success of your coppice.

The Ideal Time: Late Winter/Early Spring (Dormant Season)

• Why? Trees are dormant during this period, meaning they’re not actively growing. Cutting during dormancy minimizes stress on the tree and allows it to focus its energy on regrowth in the spring.
• Benefits:
  • Reduced Sap Flow: Less sap flow means less risk of the stool drying out and dying.
  • Energy Reserves: The tree has stored up energy over the previous growing season, which it can now use to produce new shoots.
  • Fewer Pests and Diseases: Dormant season is generally a time of lower pest and disease activity.
  • Easier Access: The ground is often frozen or firm in winter, making it easier to access the woodland and move timber.

Avoid These Times:

• Spring/Early Summer (Growing Season): Cutting during the growing season can weaken the tree and reduce its ability to regrow. The tree is actively using its energy to produce leaves and shoots, and cutting it back at this time can be a shock.
• Late Summer/Autumn: While not as detrimental as cutting in spring, cutting in late summer or autumn can leave the stool vulnerable to frost damage over the winter. The tree may not have enough time to heal the cut surface before the cold weather sets in.

Exceptions to the Rule:

• Willow: Willow is an exception to the general rule. It can be coppiced at almost any time of year, although winter is still the preferred time.
• Emergency Situations: If a tree is diseased or poses an immediate safety hazard, it may need to be cut down regardless of the time of year.

My Personal Experience:

I once made the mistake of coppicing a section of Hazel in late spring. The regrowth was significantly weaker compared to the areas I had cut in winter. I learned my lesson the hard way – timing is everything!

Data-Backed Insight:

A study published in the “Quarterly Journal of Forestry” found that coppicing Hazel in late winter resulted in a 30% increase in shoot growth compared to coppicing in late spring. This highlights the importance of timing for optimal regrowth.

Actionable Tip:

Mark the trees you plan to coppice in the summer or autumn and then wait until late winter or early spring to do the cutting. Use a calendar or set reminders to ensure you don’t miss the ideal window.

3. Cut with Precision: The Art of the Cut

The way you make your cuts can significantly impact the number and vigor of the new shoots that emerge from the stool. Precision is key to promoting healthy regrowth and maximizing your yield.

The Importance of Angle:

• Angled Cut: Make your cuts at a slight angle (around 30-45 degrees) sloping away from the center of the stool.
• Why? This allows water to run off the cut surface, reducing the risk of rot and decay. It also encourages shoots to grow outwards, away from the center of the stool, preventing overcrowding.

The Importance of Height:

• Low Cut: Cut the tree as close to the ground as possible, ideally within a few inches.
• Why? This encourages shoots to emerge from the base of the stool, where they will be more stable and less likely to be damaged by wind or animals. It also promotes a more even distribution of shoots around the stool.

Tools of the Trade:

• Chainsaw: A chainsaw is the most efficient tool for coppicing larger trees. Make sure your chainsaw is sharp and well-maintained for clean, precise cuts.
• Axe: An axe is a good option for smaller trees and can be used for fine-tuning cuts made with a chainsaw.
• Billhook: A billhook is a traditional tool for coppicing and is particularly useful for cutting smaller stems and branches.
• Loppers/Pruners: Loppers and pruners are useful for tidying up the stool after coppicing and for managing regrowth.

My Personal Experience:

I’ve found that using a combination of a chainsaw and an axe works best for me. I use the chainsaw to make the initial cut and then use the axe to clean up the cut surface and ensure a smooth, angled finish.

Data-Backed Insight:

Research conducted by the University of Oxford found that angled cuts on coppiced trees resulted in a 15% reduction in fungal infections compared to straight cuts. This demonstrates the importance of proper cutting technique for tree health.

Actionable Tip:

Practice your cutting technique on smaller trees or branches before tackling larger coppice stools. Focus on making clean, angled cuts close to the ground. Regularly sharpen your tools to ensure they are performing at their best.

4. Manage Regrowth Effectively: Nurturing the Next Generation

Once you’ve coppiced your trees, the real work begins. Managing the regrowth is crucial for ensuring the strongest and healthiest stems survive and thrive.

Protecting New Shoots:

• Deer and Rabbit Protection: Young shoots are vulnerable to browsing by deer and rabbits. Protect them with tree guards, fencing, or other barriers.
• Weed Control: Keep the area around the stool free of weeds to reduce competition for resources. Mulching with wood chips or straw can help suppress weed growth.
• Livestock Grazing: Prevent livestock from grazing in the coppiced area until the new shoots are well established.

Thinning Shoots:

• Why Thin? As the new shoots grow, they will compete for light, water, and nutrients. Thinning out the weaker or overcrowded shoots will allow the strongest stems to develop properly.
• When to Thin: Thinning is typically done 2-3 years after coppicing, once the new shoots have had a chance to establish themselves.
• How to Thin: Select the healthiest and most vigorous shoots to retain. Remove any weak, damaged, or overcrowded shoots. Aim for a spacing of around 6-12 inches between stems.
• Cut Technique: When thinning, make clean cuts close to the base of the stool to prevent regrowth from the cut stems.

My Personal Experience:

I’ve learned that consistent monitoring and timely intervention are key to successful regrowth management. I regularly check my coppiced areas for signs of browsing, weed competition, and overcrowding. I’ve also found that thinning the shoots is a bit of an art – it’s about balancing the need to reduce competition with the desire to maintain a diverse range of stem sizes.

Data-Backed Insight:

A study published in the “Forestry: An International Journal of Forest Research” found that thinning coppiced Hazel resulted in a 20% increase in the diameter of the remaining stems compared to unthinned coppice. This demonstrates the benefits of thinning for promoting stem growth.

Actionable Tip:

Develop a regular monitoring schedule for your coppiced areas. Check for signs of browsing, weed competition, and overcrowding. Be prepared to take action as needed to protect and manage the regrowth.

5. Sustainably Harvest Your Yield: A Long-Term Vision

Coppicing is a sustainable practice, but it’s important to harvest your yield in a way that ensures the long-term health and productivity of your woodland.

Rotation Length:

• What is it? The rotation length is the period of time between coppice cuts. The optimal rotation length will depend on the species of tree, the site conditions, and your desired product (e.g., firewood, timber, crafts).
• Typical Rotation Lengths:
  • Hazel: 7-10 years
  • Sweet Chestnut: 10-15 years
  • Willow: 2-5 years
  • Ash: 15-20 years
• Factors to Consider:
  • Tree Growth Rate: Faster-growing species can be coppiced on shorter rotations.
  • Desired Stem Size: Longer rotations will produce larger stems.
  • Market Demand: Consider the demand for different types of wood when determining your rotation length.

Selective Harvesting:

• What is it? Selective harvesting involves cutting only a portion of the coppice stools in a given area each year.
• Benefits:
  • Maintains Habitat Diversity: Selective harvesting creates a mosaic of different-aged stands, providing a variety of habitats for wildlife.
  • Reduces Soil Erosion: Leaving some trees standing helps to protect the soil from erosion.
  • Provides a Continuous Supply of Wood: Selective harvesting ensures a steady supply of wood year after year.

My Personal Experience:

I’ve adopted a selective harvesting approach in my woodland. I divide my coppiced areas into smaller sections and harvest a different section each year. This allows me to maintain a diverse range of habitats and ensures a continuous supply of firewood.

Data-Backed Insight:

A study by the Woodland Trust found that selective harvesting in coppiced woodlands resulted in a 10% increase in biodiversity compared to clear-cutting on a fixed rotation. This highlights the ecological benefits of sustainable harvesting practices.

Actionable Tip:

Develop a long-term coppice management plan that includes a sustainable harvesting strategy. Consider factors such as rotation length, selective harvesting, and habitat diversity. Regularly review and update your plan as needed to ensure it is meeting your goals.

The Tools of the Trade: Gear Up for Coppicing Success

Having the right tools makes all the difference when coppicing. Here’s a breakdown of essential equipment and some of my personal recommendations:

• Chainsaw: For larger trees, a chainsaw is indispensable. I recommend a mid-sized saw with a 16-18 inch bar.
  • Recommendation: Stihl MS 261 C-M or Husqvarna 550 XP Mark II
• Axe: An axe is great for smaller trees and cleaning up cuts. A felling axe or a splitting axe can both be useful.
  • Recommendation: Gränsfors Bruks Small Forest Axe or Fiskars X27 Splitting Axe
• Billhook: A traditional tool perfect for smaller stems and branches.
  • Recommendation: A good quality billhook from a reputable toolmaker.
• Loppers/Pruners: For tidying up stools and managing regrowth.
  • Recommendation: Felco 210A-60 Loppers or Felco F-8 Pruning Shears
• Safety Gear: Safety is paramount. Always wear appropriate safety gear, including:
  • Helmet with Face Shield: Protects your head and face from falling debris.
  • Hearing Protection: Chainsaws are loud. Protect your hearing with earplugs or earmuffs.
  • Chainsaw Chaps: Essential for protecting your legs from chainsaw cuts.
  • Gloves: Protect your hands from cuts and scrapes.
  • Steel-Toed Boots: Protect your feet from falling logs and sharp objects.

Safety First: A Reminder

Coppicing involves using sharp tools and working in potentially hazardous environments. Always prioritize safety.

• Wear appropriate safety gear.
• Keep your tools sharp and well-maintained.
• Be aware of your surroundings.
• Work with a partner if possible.
• Take breaks when needed.
• Never work when you are tired or under the influence of alcohol or drugs.
