silvicultur

Silviculture is the branch of forestry concerned with the establishment, growth, structure, health, and quality of forest stands to meet specific objectives. It encompasses regeneration, growth manipulation, and stand management from establishment to harvest within broader forest plans.

Objectives include timber production, biodiversity, watershed protection, carbon sequestration, and recreation. Silvicultural systems guide regeneration and stand development and are typically described as even-aged or uneven-aged, reflecting how trees of different ages are managed over time.

Regeneration can be natural or artificial. Practices such as thinning, pruning, spacing, and prescribed fire adjust density and quality. Regeneration methods include clear-cutting, shelterwood, seed-tree, and selective cutting, chosen to balance yield with ecological goals.

Planning uses inventories, site quality, and growth models to forecast outcomes and set rotation lengths. Prescriptions specify timing, intensity, and methods of intervention, while monitoring informs adaptive management.

Historically, silviculture emerged with the development of modern forestry in the 18th–19th centuries and has since integrated ecological and economic considerations. It remains central to sustainable forest management.

Environmental and policy considerations include soil and water protection, biodiversity, pest and climate risk management, and certification or policy mechanisms that promote sustainable practices.
