Silviculture
Silviculture is the practice and science of establishing, tending, and managing forests to shape their growth, composition, health, and production.
Forest regeneration: The renewal of a forest through natural establishment or deliberate planting of trees. Regeneration methods determine how a new stand begins and which species it contains.
Forest stand: A group of trees and associated vegetation occupying a defined area and sharing broadly similar conditions. Silvicultural treatments are commonly planned and evaluated at the stand scale.
Forest restoration: The process of assisting the recovery of degraded, damaged, or destroyed forest ecosystems. Silvicultural treatments can restore native composition and ecological processes.
Clearcutting: A harvesting method that removes nearly all trees from a defined area in one operation. It creates open conditions suited to regenerating species that require abundant light.
Forest biodiversity: The variety of genes, species, and ecosystems found in forests. Treatment intensity and stand structure can favor some forest species while reducing others.
Even-aged management: A system that manages stands whose trees are approximately the same age. It commonly uses clearcutting or shelterwood to establish a new, uniform cohort.
Forest succession: The changing composition and structure of a forest community over time. Management redirects, accelerates, or maintains patterns of forest change.
Agroforestry: Land-use systems that deliberately combine trees with crops, livestock, or both. Silvicultural practices help manage the tree component of integrated production systems.
Shelterwood cutting: A harvesting method that removes trees in stages while retaining a partial overstory during regeneration. It establishes a new cohort under shelter before the remaining overstory is removed.
Forest fragmentation: The division of continuous forest into smaller, more isolated patches. Harvest layout and road placement can alter habitat continuity and movement through forests.
