Variable retention harvesting evolved in the Douglas-fir region of the Pacific Northwest gradually in response to increasing dissatisfaction with the ecological consequences of clear-cutting, from the standpoint of wildlife habitat and other important forest functions. It is a harvesting technique that can provide for retention (continuity) of such structures as large and old live trees, snags. The clear felling system involves the felling and regeneration of equal areas (COUPES) each year. The forest stand in such areas has reached a pre-determined maturity. If this procedure is repeated year after year the entire rotation period, a normal series of age gradations of 1, 2,n years is established. Silvicultural Systems by John D.

The use of silvicultural systems to enhance the biological diversity of plantation forest in Britain. This review considers possible changes in the silvicultural systems applied to plantation forests in Britain, in response to demands for enhanced biodiversity.
The transformation of conifer forests in Britain — regeneration, gap size and silvicultural systems. Recent changes in forest policy require managers to introduce alternative silvicultural systems to clear-felling into windfirm conifer plantations to provide greater structural diversity and so enhance aesthetic, conservation and Cited by: The results presented here suggest that where preestablished regeneration is not abundant enough, alternative silvicultural systems such as strip clear-cutting or seed-tree systems could be used.
Abstract. This review considers possible changes in the silvicultural systems applied to plantation forests in Britain, in response to demands for enhanced biodiversity.
The options considered are: (1) extension of rotation length of selected forest stands; (2) improvement in vertical structure through variations in stand treatments such as thinning, Cited by: Silvicultural systems.
Introduction. A silvicultural system may be thought of as the process by which the crops which constitute a forest are tended, removed and replaced by new crops, resulting in the production of woods of a distinctive form (Troup, ).
Clear-cutting system. The various. Purpose of this Handbook Part –1. PART 1: GENERAL APPROACH OF THE HANDBOOK Purpose. As partial cutting silvicultural systems are being used more often in British Columbia, many questions are beginning to emerge from practitioners, whose previous experience was mainly with even-aged clearcut systems.
clear-cuts and clear-cuts with standing residuals. These silvicultural systems were used on 71 percent of logged areas. Patch, strip, and other modjfied cutting accounted for 8 percent of the volume and area logged. Seed tree and sheltelWood cutting accounted for 2 File Size: KB.
choosing a silviculture system. Silviculture systems are different approaches to harvesting, regenerating and growing forests. The three main silvicultural systems used in Ontario include: the selection system, the shelterwood system, and the clearcut system.

Clearcutting in the National Forests: Background and Overview Summary Clearcutting is a method of harvesting and regenerating trees in which all trees are cleared from a site and a new, even-aged stand of trees is grown.
Clearcutting is the primary method of timber production and management in the national forests. However, this method of harvesting trees has been controversial since at least.
The objective of this bulletin is to summarize British experience of alternative silvicultural systems to clear-cutting. Management of woodlands for diverse objectives such as recreaton, landscape, timber production and conservation is becoming increasingly important.
This booklet outlines measures which may be taken to transform even-aged forest plantations in Britain into "permanent" or "continuous cover" forest, without recourse to clear felling and replanting. Some of the perceived advantages and disadvantages are outlined and compared with the alternative of regeneration by clear felling and by: 6.
This book describes the theoretical basis and practical application of 20 diverse silvicultural systems for the benefit of ecologists, land-use managers and other professionals.
These systems offer the key to regenerating, tending, and harvesting forests in an era of rapid deforestation and increasing demand for wood as fuel and building material.

Vol 4, No 3, page 38 Althaea officinalis. Vol 8, No 4, page 6. Proponents of continuous cover silviculture in Britain see silvicultural systems such as selection and irregular shelterwoods being the `ideal' to replace clear-cutting (Yorke, ).
However, when managing to make plantations spatially heterogeneous, many silvicultural systems have a part to play and there is no one `ideal' solution. Clearcutting has generated considerable controversy due to the indiscriminate nature of the cutting; during a clearcut, nearly all trees are removed without consideration of type, age or the effect this will have on the ecosystem.
However, many maintain that clearcutting also produces benefits. Silvicultural description of stands.

Silvicultural System A planned process whereby a stand is. The type of silvicultural system—even age (clear-cut, shelterwood, or seed tree), or all age—and the various activities such as site preparation, thinning, and herbicide use associated with the cutting system can either create or alleviate pest problems and certainly can affect the natural enemies of.
A silvicultural system is the collection of treatments to be applied over the life of a stand. These systems are typically described by the method of harvest and regeneration employed. In general these systems are: Clearcutting: The entire stand is cut at one time and naturally or artificially regenerate.
THE USE OF ALTERNATIVE SILVICULTURAL SYSTEMS Continuous cover forestry commits a forest manager to using an alternative silvicultural system to patch clearfelling. The choice of alternative system should be based upon an understanding of species requirements, site potential, climatic limitations and linked to management objectives.
Selective cutting, also called selective thinning, involves carefully choosing which trees to log, while leaving the rest of the forest intact. This process allows for better yield and productivity over several decades. Each year provides trees for harvest, rather than having to wait a minimum of sixty years after a clear cut.
According to. This is the fourth silvicultural guide for northern hardwoods (beech-birch-maple) in the Northeast. This guide is a revision of the most recent one published in (Leak et al.
This new guide provides updated information compiled from decades of research Cited by: From operational or economic standpoints, however, there are disadvantages to the shelterwood system: harvesting costs are higher; trees left for deferred cutting may be damaged during the regeneration cut or related extraction operations; the increased risk of blowdown threatens the seed source; damage from bark beetles is likely to increase; regeneration may be damaged during the final cut and related.

History of Pro Silva Forestry Shelterwood Systems were introduced toward the end of the 18th Century in Germany, but it was not until G. Hartig published his famous book in entitled ‘Instructions on wood cultivation for the forester’, that the Shelterwood System became widely popular and dominated German forestry in the 19th century.
Clearcutting, clearfelling or clearcut logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Along with shelterwood and seed tree harvests, it is used by foresters to create certain types of forest ecosystems and to promote select species that require an abundance of sunlight or grow in large, even-age stands.
