• Forests capture solar energy, store water and nutrients, moderate climates, develop and condition soils, serve as carbon resevoirs, and serve as important habitat for various life forms
• Forests are also a wonderful place for recreation

• 35% of municipal waste (garbage) consists of paper and paper products
• Most paper products can be recycled• Wastepaper can be recycled 7 times before the fibre
becomes too short to produce good newsprint• Canada currently recovers 31% of the paper it consumes

Shelterwood Cutting
Selective cutting
Methods of Harvesting Forests
Trees up to 25" in diameter can be cut with the XL25.

When replanted, the new forest grows uniformly in
species and sizeVIDEO
Methods of Harvesting Forests
Clear 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
