  1. Humans Impacting the Environment: Forestry

  2. Forestry • Canada’s Forest Resource • Methods of Harvesting Forests • Forestry Issues

  3. Canada’s Forest Resource Boreal Shield Pacific Maritime Montane Cordillera

  4. Canada’s Forest Resource Pacific Maritime Boreal Shield Montane Cordillera

  5. Boreal Forest Boreal means northern in Russian Boreal Shield

  6. Boreal Forest

  7. Boreal Forest The northern Boreal Forest is dominated by only two species of trees - Black Spruce and White Spruce. Taiga is the Russian word for forest.

  8. Boreal Forest Black Spruce White Spruce Balsam Fir Jack Pine Cedar Tamarack White Birch Poplar

  9. Pacific Maritime Forest Pacific Maritime

  10. Pacific Maritime Forest Douglas Fir Sitka Spruce

  11. Pacific Maritime Forest Western Red Cedar Western Hemlock

  12. Montane Cordillera Forest Montane Cordillera

  13. Montane Cordillera Forest Ponderosa Pine Engelmann Spruce Douglas Fir

  14. Value of Forest Industry Pulp and Paper Products Other Provinces $7286 million Quebec $11575 million British Columbia $7514 million Ontario $10018 million

  15. Value of Forest Industry Wood Products Other Provinces $780 million New Brunswick $751 million Alberta $1731 million British Columbia $11 234 million Ontario $3454 million Quebec $5306 million

  16. Methods of Harvesting Forests Clear-cutting Shelterwood Cutting Selective cutting

  17. Methods of Harvesting Forests Trees up to 25" in diameter can be cut with the XL25.

  18. Methods of Harvesting Forests Clear Cutting Loggers remove every tree and leave a barren landscape. When replanted, the new forest grows uniformly in species and size

  19. Methods of Harvesting Forests Shelterwood Cutting Involves clear-cutting only part of an old growth forest Small groups of seed bearing trees are left so the area will regenerate. Shelterwood method is often used in forests that have grown and aged evenly

  20. Methods of Harvesting Forests Selective Cutting Only mature trees of the desired size, type or quality Another shot of the same stand in an area that has been finished--except for picking up a few logs.  The stand is about 65 years old.

  21. Forestry Issues Too few trees are replanted? = Soil erosion

  22. Forestry Issues Clogged Rivers

  23. Forestry Issues Water Pollution Air Pollution

  24. Forestry Issues Aerial Spraying Forest Fires

  25. Forestry Issues Destruction of Wildlife Habitat
