Canada’s commercial and non commercial forest

In what ways are Canada's different forest used for commercial purposes? Boreal- pulp and paper (small trees) Taiga- too far from markets- some for pulp and paper West Coast Forest- largest volume of wood per hectare, large trees for lumber, cedar shingles and plywood Montane Forest- 2 nd largest volume of wood per hectare, lumber and pulp and paper Mixed Forest- conferous trees are used for lumber and pulp and paper, deciduous used for flooring and furniture making, maple, cherry, birch
Clear cutting in Kelowna, British Columbia. ↑ Shelter wood logging. ↓ Selective cutting, BC ↑

Transporting logs by truck from where they have been extracted. ↑ → Logs being transported by boat. →
Saw mills tend to be much smaller operations than pulp and paper Each mill specializes in a particular market Number of saw mills have decline from 900 to 850. New mills replace old fashioned mills that were designed to just saw logs, new mills reduce waster and parts of the log that were thrown out 30 years ago are now used eg. Particle board and bark and sawdust are burned to help power the mill
STEP 1 STEP 2 STEP 3 2 blades cut off parts of the wood that cant be used. ← While being examined blades cut the logs in to needed sizes. ↑ Logs are sent down a conveyer belt to be shipped off. →
STEP 1 STEP 2 STEP 3 Using pressure jets of water to remove bark. Very efficient Doesn’t work in area with cold climate
33% of all our exports is forestry. The highest % of any group. ← We make 81 billion dollars a year off lumber. 40 billion dollars of wood is exported. Forestry creates 360 000 direct jobs and 500 000 indirect ones. →
What economic impact does the forestry industry have in Canada? Pulp and Paper Quebec (11 993 million), Ontario (11 115 million) and British Columbia (6264 million ) have most mills (other provinces 13 551 million) Lumber- British Columbia (10 817 million) Quebec (8032 million) Ontario (5664 million) 5610 million from other provinces
Wasted lumber from production. Biggest problem in production. Solution have been created though. Multi wood chips ↓ Plywood ↑
ACID PRECIPITATION CAUSED BY EMISSIONS FROM FACTORIES PREVAILING WINDS CARRY EMISSIONS TREES ARE WEAKENED AND TURN YELLOW THOSE THAT DON’T DIE OUTRIGHT GROW MORE SLOWLY
Once clear-cut trees cannot provide humus for the soil making it extremely hard for anything to grow back. Unhealthy soil. ← Mountain pine beetle that has been devouring forests.
Habitat loss. Global warming increased. Destroyed ecozones. Unfertile soil. → Air pollution.
LUMBERLUMBER Need for lumber is at its highest and will just keep increasing Many new homes and suburbs being built. New city development → The need for paper is high.
