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 $ 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 When replanted, the new forest grows uniformly in species and size
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 Only mature trees of the desired size, type or quality
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
