Study Notes
Lumbering Overview
- Lumbering refers to tree cutting for wood production in domestic, industrial, or commercial sectors.
- The four phases of lumbering are logging, driving, manufacturing, and transport.
- Logging is typically limited to winter months when snow and ice facilitate transportation.
Logging Process
- Logs are dragged by horses or oxen over snow-covered terrains to collection points.
- Driving is the movement of logs from collection points to sawmills, utilizing railroads when necessary.
- Manufacturing cuts logs into lumber products such as planks and boards, primarily for construction and paper.
- Transport includes finding buyers and delivery to markets, with local mills selling to nearby residents.
Lumbering in Canada
- Canada, rich in coniferous forests, covers about 40% of its land area with these resources.
- Major forests extend from Newfoundland to British Columbia, facilitating extensive lumber production.
- Canada is the world's leading wood products exporter, contributing to one-third of global lumber and timber markets.
- Lumbering is a significant winter activity; logs are temporarily stored on frozen rivers for spring transport.
Tree Species
- Lumber is produced from hardwood (e.g., oak, maple, birch) and softwood (e.g., pine, fir, spruce) trees.
- Canadian forestry is dominated by softwood species, specifically spruce, pine, and hemlock, primarily harvested in British Columbia.
- Hardwood lumber production is concentrated in Ontario and Quebec.
Lumbering Products
- Key products include lumber, veneer, plywood, particle board, wood pellets, and engineered wood.
- Manufacturing processes involve mechanical methods such as sawing and peeling.
Manufacturing Process
- Inspection involves cleaning logs and checking for defects before processing.
- Debarking uses high-powered jets or cutting blades to remove bark, often repurposed for decoration.
- Logs are cut into sizes (bucking logs) for various uses, with water sprayed to avoid drying.
- Cutting and edging involve optical sensors and computer mapping for optimal cuts, with manual oversight.
- Planing and grading prepare the wood, ensuring quality before packaging and shipment.
Factors Favoring Lumbering
- Limited species of coniferous trees are well-suited for winter logging.
- Frozen ground facilitates easier transport of logs to rivers for floating to sawmills.
- Access to hydroelectricity enhances sawmill operation in mountainous regions, supporting efficient lumbering.
Life of a Lumberjack
- Lumberjacks epitomize strength and masculinity in Canada, crucial to the timber industry since its rise.
- In the 19th century, half of Canadian males were lumberjacks; modern machinery now allows female participation.
Environmental Effects of Lumbering
- Biodiversity Loss: Habitat destruction threatens species survival and ecosystems reliant on primary trees.
- Erosion: The loss of trees leads to soil degradation and nutrient loss, making environments barren.
- Flooding: Deforestation compromises soil stability, increasing risks of floods and mudslides, endangering lives and properties.
- River Obstruction: Soil erosion leads to sedimentation in rivers, disrupting aquatic habitats critical for species like salmon.
- Climate Change: Deforestation releases stored carbon, increasing greenhouse gas concentrations and contributing to global warming's adverse effects, including extreme weather events.
