Single Tree Selection
Individual trees are selected for harvesting based on specific criteria. This method creates a forest with many age classes and maintains continual cover.
Seed Tree Cutting
A small number of healthy and desirable seed-producing trees are left standing so they can reseed the area. These trees are later removed once regeneration has been established.
High-grading
A form of selective cutting where the largest and most valuable trees are harvested, often leading to a high genetic loss and a decline in the overall quality and health of the remaining stand.
Strip Cutting
Trees are clearcut in narrow strips that are alternated with uncut areas to protect the soil and regenerate the forest. The strips gradually shift over the landscape as the forest regrows.
Selective Cutting
Trees are selectively removed based on specific criteria, such as size, species, or condition. This method better maintains the ecological diversity of a forest and is often used for hardwoods.
Sanitation Cutting
Harvesting attempts to remove diseased, damaged, or dying trees to reduce the spread of pests or pathogens. It improves the overall health and quality of the forest.
Shelterwood Cutting
Some trees are left to provide shelter for the regeneration of a new crop of seedlings. The remaining trees are removed in subsequent cuttings. Often used in forests managed for continuous cover forestry.
Clearcutting
A method where all trees in an area are uniformly cut down. Often used when the stand of trees is uniform in species composition and age, and when the goal is to create a new, even-aged stand of trees.
Group Selection Cutting
Small groups of trees are harvested in small patches to simulate the effects of natural disturbances. This method helps maintain a mixture of tree species and ages.
Coppicing
Trees are cut down to near ground level, and new shoots regrow from the stumps. This ancient method can be sustainable but is species-dependent.
