• Moisture Content: Freshly cut wood has a high moisture content (often above 40%), which makes it difficult to burn. Wood needs to be dried to a moisture content of 15-20% for optimal burning.
• Species Characteristics: Different wood species have different burning characteristics. For example, some woods produce more smoke than others. Some woods throw sparks, and some have odors.

Wood Processing Methods:

• Felling: The process of cutting down a tree.
  • Technical Requirement: Proper felling techniques are essential for safety. Always assess the tree’s lean, wind direction, and surrounding obstacles before felling.
  • Safety Code: OSHA regulations require loggers to wear appropriate personal protective equipment (PPE) and to follow safe felling practices.
• Bucking: The process of cutting a felled tree into logs.
  • Technical Requirement: Bucking logs to the appropriate length is important for efficient splitting and stacking. A common length for firewood is 16 inches.
  • Practical Tip: Use a measuring stick or tape measure to ensure consistent log lengths.
• Splitting: The process of splitting logs into smaller pieces for firewood.
  • Technical Requirement: Splitting wood along the grain is easier and more efficient.
  • Tool Requirement: Use a maul or splitting axe for manual splitting, or a log splitter for larger volumes of wood.
• Stacking: The process of stacking firewood to allow it to dry.
  • Technical Requirement: Stack firewood in a single row, off the ground, and in a sunny, well-ventilated location.
  • Drying Tolerances: Aim for a moisture content of 15-20% before burning.

Data Points:

• Cord Volume: A standard cord of firewood is 4 feet high, 4 feet wide, and 8 feet long (128 cubic feet).
• Log Diameter Measurement: Measure log diameter at the midpoint of the log.
