Clear-cutting Shelterwood Cutting Selective cutting Methods of Harvesting Forests

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

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