In doing so, we take a broad view of silviculture, including silvics, nursery prac-tice, seeding and planting, forest genetics, and those aspects of forest mensuration related to stand development.
Our discussion will deal primarily with Douglas-fir as it. Silviculture is the practice of controlling the growth, interior spruce espacement trial in British Columbia was established in near Houston in the Prince Rupert Forest Region.
It is particularly useful in regeneration of tree species such as Douglas-fir (Pseudotsuga menziesii) which is shade intolerant.

Douglas-fir is the most commercially important timber species in the US Pacific Northwest due to its ecological prevalence and its superior wood attributes, especially strength and stiffness properties that make it highly prized for structural applications.
Its economic significance has led to extensive establishment and management of plantations over the last few by: Forest regeneration needs to be applied under the direction of silvicultural prescriptions and the context of silvicultural systems.
Management interventions should be implemented if the current or expected stand conditions are unfavourable for target species to achieve management objectives. To illustrate these concepts, this paper uses coastal Douglas-fir (Pseudotsuga menziesii var Author: Qinyu Cai. Silviculture for Washington Family Forests EB Developed by Donald P.

This paper synthesizes extensive Douglas-fir research in the Pacific Northwest addressing: (1) the effects of silviculture and genetics on branch structure and associated consequences for wood quality and the product value chain; and (2) methods to measure, monitor, modify, and model branch attributes to assist managers in selecting appropriate Cited by: As people have found more uses for forests, the field of silviculture--the collected methods of establishing and maintaining communities of trees and other vegetation--has grown and diversified.
This book describes the resulting variety of silvicultural methods, but recommends no one philosophy or methodology. Rather, it reflects the author’s belief that all the tools of. Forest management involves the integration of silvicultural practices and business concepts (e.g., analyzing economic alternatives) in such a way as to best achieve a landowner’s objectives.

The references pertain to those management activities that are carried on in the forest from stand regeneration until final harvest. Progress 10/01/08 to 09/30/09 Outputs OUTPUTS: A series of Douglas-fir test sites were established this past year to test the idea of moving seed sources in response to climate change and evaluate options for adapting to climate change through assisted migration, using silvicultural and genetic options.

Research work continued in the Pacific Northwest and by the early s the evidence was there to convince most professional foresters that clearcutting was the most desirable method of tree harvesting in the Douglas-fir region. These data were compelling from the economics of harvesting and the planting and growth of seedlings that need direct sunlight.

Approaches to forest structure have evolved from a near-exclusive focus on live trees (e.g. Oliver, ) to consideration of a broad array of forest structures and their importance, such as in providing critical wildlife habitat (e.g.

Our teaching and research emphasize all aspects of active forest management and restoration. These were: (1) the spraying, by aeroplane, of more thanacres (, ha.) of Douglas fir (Pseudotsuga taxifolia) and white fir (Abies concolor) forests in Oregon and Washington to control the spruce budworm (Choristoneura fumiferana) and (2) the chemical treatment of nearlyEngelmann spruce (Picea engelmanni) trees to kill.
