Birch Tree Wood Burning Benefits (Expert Tips for Arborists)
The State of the Firewood Industry: A Global Perspective
Before we dive into the nitty-gritty of birch, let’s take a moment to appreciate the broader context. The global firewood market is a surprisingly robust one. While precise figures are difficult to pin down due to the informal nature of many transactions, estimates suggest a multi-billion dollar industry worldwide. In Europe, for example, firewood remains a significant heating source, particularly in rural areas. A 2022 report by the European Biomass Association (Bioenergy Europe) indicated that wood fuel accounted for approximately 40% of renewable energy consumption for heating.
In North America, the story is similar. While natural gas and electricity dominate the heating market, firewood maintains a steady presence, fueled by wood stoves, fireplaces, and outdoor fire pits. The U.S. Energy Information Administration (EIA) reports that wood energy consumption has remained relatively stable over the past decade, suggesting a consistent demand for firewood.
What’s driving this demand? Several factors are at play:
- Rising Energy Costs: As fossil fuel prices fluctuate, firewood offers a more stable and often more affordable alternative.
- Renewable Energy Focus: Firewood, when sourced sustainably, is a renewable energy source, appealing to environmentally conscious consumers.
- Off-Grid Living: The increasing popularity of off-grid living and homesteading has boosted the demand for firewood as a primary heating source.
- Tradition and Aesthetics: For many, the ambiance and tradition of a wood-burning fire are simply irreplaceable.
However, the industry faces challenges:
- Sustainability Concerns: Unsustainable logging practices can lead to deforestation and habitat loss. Responsible sourcing is crucial.
- Air Quality Issues: Wood smoke can contribute to air pollution, particularly in densely populated areas. Efficient wood stoves and proper burning techniques are essential.
- Competition from Other Fuels: Natural gas, propane, and electricity continue to offer convenience and, in some cases, lower costs.
As professionals involved in wood processing, we have a responsibility to address these challenges and promote sustainable and responsible practices. Now, let’s get back to the star of our show: birch.
Why Birch? Unveiling the Benefits
Birch wood often gets a bad rap. Some say it burns too quickly, others complain about the smell. But I’m here to tell you that, with the right knowledge and preparation, birch can be an excellent firewood option, especially when you understand its unique properties.
The Science Behind the Burn: Understanding Birch’s Composition
Birch wood is a hardwood, but it’s on the softer side compared to oaks or maples. This means it’s easier to split and ignite, making it a great choice for kindling or starting a fire. However, its lower density also means it burns faster.
The key to understanding birch’s burning characteristics lies in its chemical composition. Birch contains a significant amount of volatile oils, particularly betulin, which is found in the bark. These oils contribute to its distinctive aroma and its ability to ignite easily, even when slightly damp.
Here’s a quick breakdown of birch’s key properties:
- Density: Moderate (around 42 lbs/cubic foot when dry)
- BTU Content: Approximately 20 million BTU per cord (lower than oak or maple, but higher than softwoods like pine)
- Drying Time: Relatively fast (6-12 months)
- Smoke Production: Moderate (can be reduced with proper seasoning)
- Sparking: Low to moderate
Debunking the Myths: Addressing Common Misconceptions
Let’s tackle some common misconceptions about birch firewood:
- Myth: Birch burns too quickly.
- Reality: While it does burn faster than denser hardwoods, this can be an advantage for quickly heating a space or starting a fire.
- Myth: Birch smells bad when it burns.
- Reality: Freshly cut birch can have a slightly resinous smell, but properly seasoned birch has a pleasant, slightly sweet aroma.
- Myth: Birch is not worth the effort.
- Reality: Birch is readily available in many regions, relatively easy to process, and provides decent heat output.
The Arborist’s Advantage: Why Birch is a Smart Choice
As arborists, we often encounter birch trees that need to be removed due to disease, storm damage, or safety concerns. Instead of letting this valuable resource go to waste, we can transform it into firewood. Here’s why birch is a smart choice for arborists:
- Abundance: Birch is a common tree species in many regions, making it readily available.
- Ease of Processing: Birch is relatively easy to fell, delimb, and split compared to some other hardwoods.
- Quick Drying Time: Birch dries faster than denser hardwoods, allowing for a quicker turnaround time from tree to firewood.
- Marketability: While it may not fetch the highest price, birch firewood is still marketable, providing an additional revenue stream.
From Tree to Firewood: A Step-by-Step Guide
Now, let’s get down to the practicalities of turning a birch tree into usable firewood.
Step 1: Felling the Tree Safely
Safety is paramount when felling any tree, especially for professional arborists. Here’s a breakdown of the key steps:
- Assessment: Before you even think about starting your chainsaw, assess the tree and its surroundings. Look for:
- Lean: Which way is the tree naturally leaning?
- Branches: Are there any dead or hanging branches that could fall unexpectedly?
- Obstacles: Are there any power lines, buildings, or other obstacles in the path of the falling tree?
- Wind: How strong is the wind, and which direction is it blowing?
- Planning: Develop a felling plan that takes into account all of the factors mentioned above. Determine the direction of fall and clear a path for escape.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, including:
- Helmet: Protects your head from falling debris.
- Eye Protection: Safety glasses or goggles protect your eyes from sawdust and flying chips.
- Hearing Protection: Earplugs or earmuffs protect your hearing from the noise of the chainsaw.
- Gloves: Provide a better grip and protect your hands from cuts and abrasions.
- Chainsaw Chaps: Protect your legs from chainsaw injuries.
- Steel-Toed Boots: Protect your feet from falling logs.
- The Notch: The notch is a critical cut that helps control the direction of fall.
- Open-Faced Notch: This is the most common type of notch and provides good control. It involves making two cuts: a horizontal cut and a sloping cut that meet at an angle of approximately 70 degrees.
- Hinge: The hinge is the uncut wood between the notch and the back cut. It controls the direction of fall and prevents the tree from kicking back.
- The Back Cut: The back cut is made on the opposite side of the tree from the notch.
- Leave a Hinge: Be sure to leave a hinge of sufficient thickness to control the fall.
- Wedges: Use wedges to prevent the tree from pinching the saw and to help direct the fall.
- Felling: Once the back cut is complete, use wedges to push the tree over.
- Escape Route: Move away from the tree along your pre-planned escape route as it falls.
- Calling “Timber!”: Shout “Timber!” loudly to warn anyone in the area.
Tool Selection:
- Chainsaw: Choose a chainsaw that is appropriate for the size of the tree. A 16-20 inch bar is generally sufficient for most birch trees. I personally prefer a Stihl MS 261 for its balance of power and maneuverability, but a Husqvarna 550 XP Mark II is another excellent option.
- Axes and Wedges: Use a felling axe or wedges to help direct the fall of the tree.
- Measuring Tape: Use a measuring tape to accurately measure the diameter of the tree and determine the appropriate size of the notch and back cut.
- First Aid Kit: Always have a well-stocked first aid kit on hand in case of accidents.
Step 2: Delimbing and Bucking
Once the tree is on the ground, it’s time to delimb it and buck it into manageable lengths.
- Delimbing: Remove all of the branches from the trunk.
- Chainsaw: Use a chainsaw to cut off the larger branches.
- Axe: Use an axe to chop off the smaller branches.
- Work Safely: Be careful not to cut yourself or others with the chainsaw or axe.
- Bucking: Cut the trunk into lengths that are appropriate for your wood stove or fireplace.
- Standard Lengths: 16 inches is a common length, but you may need to adjust this depending on the size of your firebox.
- Measuring: Use a measuring tape to ensure that all of the pieces are the same length.
- Cutting Technique: Cut the trunk from both sides to prevent the saw from pinching.
Tool Selection:
- Chainsaw: A smaller chainsaw with a 14-16 inch bar is ideal for delimbing and bucking smaller diameter birch. I often switch to a lighter saw like a Stihl MS 170 for this stage.
- Bucking Saw: A bucking saw can be used for smaller branches and for making precise cuts.
- Measuring Tape: Essential for accurate bucking.
Step 3: Splitting the Logs
Splitting the logs is necessary to speed up the drying process and make the firewood easier to handle.
- Safety First: Wear safety glasses and gloves to protect your eyes and hands.
- Choose Your Method:
- Axe: A splitting axe is the traditional tool for splitting logs.
- Technique: Place the log on a chopping block and swing the axe down onto the center of the log.
- Stance: Maintain a wide stance for balance and control.
- Hydraulic Log Splitter: A hydraulic log splitter is a powered machine that uses hydraulic pressure to split logs.
- Efficiency: This is a much faster and easier method for splitting large quantities of wood.
- Safety: Always follow the manufacturer’s instructions and wear appropriate safety gear. I use a 27-ton splitter from Champion Power Equipment, which has handled even the most knotty birch with ease.
- Axe: A splitting axe is the traditional tool for splitting logs.
- Splitting Knots: Knots can be difficult to split.
- Target the Weak Points: Try to split the log along the grain, avoiding the knot.
- Wedges: Use wedges to help split the log through the knot.
Tool Selection:
- Splitting Axe: A good quality splitting axe is essential for manual splitting. Fiskars makes excellent axes that are durable and effective.
- Hydraulic Log Splitter: If you plan to split a lot of wood, a hydraulic log splitter is a worthwhile investment.
- Wedges: Use wedges to help split difficult logs.
- Sledgehammer: A sledgehammer can be used to drive wedges into logs.
- Chopping Block: A sturdy chopping block provides a stable surface for splitting logs. I use a large, seasoned oak round for my chopping block.
Step 4: Seasoning the Firewood
Seasoning is the process of drying the firewood to reduce its moisture content. Properly seasoned firewood burns hotter, cleaner, and produces less smoke.
- Moisture Content: Aim for a moisture content of 20% or less.
- Moisture Meter: Use a moisture meter to check the moisture content of the wood. These are inexpensive and readily available online.
- Visual Inspection: Seasoned firewood will be lighter in weight, have cracks in the ends, and make a hollow sound when struck together.
- Stacking: Stack the firewood in a way that allows for good air circulation.
- Elevated: Stack the firewood on pallets or rails to keep it off the ground.
- Spacing: Leave space between the rows of firewood to allow for air to circulate.
- Sun and Wind: Stack the firewood in a sunny and windy location.
- Drying Time: Birch typically takes 6-12 months to season properly.
- Climate: The drying time will vary depending on the climate.
- Monitoring: Check the moisture content regularly to ensure that the firewood is drying properly.
Stacking Techniques:
- The Traditional Stack: This involves stacking the firewood in rows, with each row leaning slightly inward.
- The Holzhaufen: This is a circular stack of firewood that is popular in Germany and Austria. It provides excellent air circulation and protects the firewood from the elements. I’ve experimented with this method and found it particularly effective for birch, as the circular design encourages airflow around the entire stack.
- The Criss-Cross Stack: This involves stacking the firewood in a criss-cross pattern, which creates air gaps between the logs.
Data Points and Statistics:
- A study by the University of Maine found that properly seasoned firewood can produce up to 50% more heat than green wood.
- The same study found that burning green wood can increase creosote buildup in your chimney, increasing the risk of chimney fires.
- My own experiments have shown that birch firewood seasoned for 12 months consistently achieves a moisture content of below 20% in my local climate (coastal Oregon).
Step 5: Storing the Firewood
Once the firewood is seasoned, it’s important to store it properly to keep it dry and protected from the elements.
- Covered Storage: Store the firewood in a shed, garage, or under a tarp.
- Ventilation: Ensure that the storage area is well-ventilated to prevent moisture buildup.
- Pest Control: Take steps to prevent pests from infesting the firewood.
- Elevated Storage: Keep the firewood off the ground to prevent insects from crawling into it.
- Regular Inspection: Inspect the firewood regularly for signs of pests.
Birch Firewood: Burning Tips and Best Practices
Now that you’ve properly prepared your birch firewood, let’s talk about how to burn it effectively.
Starting a Fire with Birch: Kindling is Key
Birch bark is an excellent natural fire starter. It contains volatile oils that ignite easily, even when slightly damp.
- Gather Kindling: Gather small pieces of birch bark and twigs.
- Build a Teepee: Build a small teepee of kindling in your firebox.
- Light the Kindling: Light the kindling with a match or lighter.
- Add Larger Pieces: Once the kindling is burning well, add larger pieces of birch firewood.

- Equipment Costs: Chainsaw, axe, log splitter (rental or purchase), safety gear. Prioritize safety gear first. A good quality chainsaw can be a significant investment, but it’s a worthwhile one if you plan to process a lot of wood. Consider buying used equipment to save money. I started with a used Stihl MS 250 that I picked up for a steal.
- Fuel and Maintenance: Chainsaw fuel, bar oil, chain sharpening, log splitter maintenance. Don’t underestimate these ongoing costs.
- Storage Costs: Tarp, shed, or other storage solutions. A simple tarp can be a cost-effective way to protect your firewood from the elements.
- Labor Costs: Your time! Be honest about how much your time is worth.
Tip: If you’re an arborist, you can significantly reduce costs by utilizing trees that you’re already removing for other purposes. This turns a disposal cost into a potential revenue stream.
Case Study: A Successful Birch Firewood Project
I once worked on a project where we had to remove several large birch trees from a homeowner’s property due to root rot. Instead of simply hauling the trees away, we offered to process them into firewood for the homeowner.
- The Process: We felled the trees, delimbed them, bucked them into 16-inch lengths, and split them using a hydraulic log splitter.
- The Challenge: The biggest challenge was the sheer volume of wood. It took us several days to process all of the trees.
- The Solution: We organized the work efficiently, using a team of three people. One person felled and delimbed the trees, another person bucked the logs, and the third person split the wood and stacked it for seasoning.
- The Result: The homeowner was thrilled to have a large supply of firewood for the winter. We were able to dispose of the trees in an environmentally friendly way and generate additional revenue for our business.
- Lessons Learned: This project taught me the importance of planning, organization, and teamwork when processing large quantities of firewood. It also reinforced the value of birch as a viable firewood option.
