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.
