  • Pre-Commercial Thinning Is a Method to Reduce the Number of Trees Per
    Natural Resources Conservation Service Technical Forestry Note TX-FS-12-6 Pre-commercial thinning releases over-crowded pine or hardwood stands to prevent stagnation, decrease the risk of insects and disease, and increase the growth of remaining trees. Trees are typically removed by mowing, disking, chopping, cutting, spraying or prescribed burning. More details found in the text…. Pre-commercial thinning – Benefits/Costs? What is pre-commercial thinning? Pre-commercial thinning is a thinning method performed prior to trees reaching merchantable size, typically around 4.5 inches dbh (diameter at breast height measured at 4.5 ft. above the ground). The objective of a pre-commercial thinning is to release some trees in overstocked stands by reducing densities to prevent stagnation and increase the growth of the remaining trees. Many southern pine species regenerate by producing a great deal of seed, resulting in thousands of seedlings per acre. Loblolly pine, for example, can be a prolific seed producer under ideal conditions. Natural regeneration practices in even-aged systems through seed-tree or shelterwood methods often results in extreme overstocked conditions that, left untreated, can stagnate growth and lengthen rotation ages (Mann and Lohrey 1974). The decision to pre-commercially thin a stand is often difficult for many landowners because of the initial costs involved with implementing this treatment. However, allowing trees to continue growing in overstocked conditions will ultimately result in a stand of trees with small diameters and small crowns. Pine trees generally need about one-third of the total height in live crown to sustain effective growth rates over the span of the stand rotation.

  • Evolution of Silvicultural Thinning: from Rejection to Transcendence
    EVOLUTION OF SILVICULTURAL THINNING: FROM REJECTION TO TRANSCENDENCE Boris Zeide1 Abstract—Our views on a main tool of forestry, silvicultural thinning, have changed greatly since the beginning of forestry over 200 years ago. At first, thinning was rejected as something unnatural and destructive. It was believed that the densest stands were the most productive and any thinning only detracted from maximum growth produced by nature. This philosophy was still dominant during the second stage when the “fathers” of forestry developed the practice of light thinning from below. It took another 100 years to acknowledge the benefit of a less “natural” medium to heavy thinning. During the last 70 years, the consensus has been that, within a wide range of densities, stand growth remains more or less constant. Even better results can be achieved when density increases with age. Heavy thinning at the beginning speeds up growth, whereas higher stocking at the end secures a larger final harvest. The last stage takes the trend of progressively lighter thinning to its logical conclusion: to control density by planting only the trees we intend to harvest at the end of rotation. Wood quality and stem form can be improved by pruning. Specific management recommendations are provided. INTRODUCTION overlooks the critical difference between natural and planted Our attitude toward silvicultural thinning has evolved from regeneration–-us. Only few trees survive until maturity under total prohibition to the realization that thinning is not the best natural conditions and almost all when we control intra-and method to control stand density and maximize yield.

Unless some of the trees die or are removed, others cannot continue to grow.

  • Developing Optimal Commercial Thinning Prescriptions: a New Graphical Approach
    Developing Optimal Commercial Thinning Prescriptions: A New Graphical Approach KaDonna C. Randolph, USDA Forest Service Forest Inventory and Analysis, Knoxville, TN 37919; and Robert S. Seymour and Robert G. Wagner, Department of Forest Ecosystem Science, University of Maine, Orono, ME 04469. ABSTRACT: We describe an alternative approach to the traditional stand-density management diagrams and stocking guides for determining optimum commercial thinning prescriptions. Predictions from a stand-growth simulator are incorporated into multiple nomograms that graphically display postthinning responses of various financial and biological response variables (mean annual increment, piece size, final harvest cost, total wood cost, and net present value). A customized ArcView GIS computer interface (ThinME) displays multiple nomograms and serves as a tool for forest managers to balance a variety of competing objectives when developing commercial thinning prescriptions. ThinME provides a means to evaluate simultaneously three key questions about commercial thinning: (1) When should thinning occur? (2) How much should be removed? and (3) When should the final harvest occur, to satisfy a given set of management objectives? North. J. Appl. For. 22(3):170–174.

SD396.5.G84 1999 634.9'53'09711 C99-960223-3 1999 Province of British Columbia To view a copy online, see: www.for.gov.bc.ca/hfp/pubs.htm Preface Commercial thinning is an intermediate harvest where the merchantable wood removed should cover part or all of the cost of harvesting. It is defined as a thinning “in which all or part of the felled trees are extracted for useful products…” (Smith, 1986). Commercial thinning, when carried out on the right stands at the right time under appropriate stand conditions, is a valuable strategic management tool that increases the flexibility in the timing and quantity of wood flow available at the forest estate level. The Guidelines for Commercial Thinning were developed with input from industry (COFI), Ministry of Environment, Lands and Parks, MOF regions and districts, Research Branch, Economics & Trades Branch, Resource Tenures & Engineering Branch, Compliance and Enforcement, and Forest Practices Branch staff. These guidelines provide information to forest practitioners considering commercial thinning and those that are currently planning and implementing commercial thinning programs in BC. This document provides important information on: 1. the effects of commercial thinning on the growth of trees and stands 2. the importance of planning at the regional, landscape and stand levels 3. the guidance for inclusion of silviculture prescription data elements for commercial thinning 4.

The Olympic Habitat Development Study, a cooperative project between the Pacific Northwest Research Station and the Olympic National Forest, began in 1994 to examine this question. It uses a novel type of variable-density thinning called thinning with skips and gaps. Ten percent of the study area was left unthinned, while 15 percent was cleared to create openings in the forest canopy. These gaps also yielded most of the merchantable timber.

  • Carbon Sequestration and Forest Land Thinning April 2008
    Alaska Forestry Technical Note 1 Carbon Sequestration and Forest Land Thinning April 2008 Does Thinning Increase Carbon Sequestration in Forest Stands? Current literature and research indicates that the use of thinning to increase the amount of total carbon sequestered does not always achieve the desire results. This is due to the management regime that must be developed to maximize carbon sequestration. Most forestland management is industrial based where getting a product to useful size in the shortest amount of time is one of the major objectives for the landowner. This is often in conflict with the management scenarios for carbon sequestration, which often involve long term forest harvest cycles. Alaska has some unique forests that grow very slowly compared to many other forested areas in North America. These vast expanses of forest being managed for long harvest rotations may fit into the carbon sequestration model, but may not fit most industrial models. In Alaska one of the factors in determining EQIP eligibility and ranking is the ability to mitigate the effects of atmospheric emissions; the following should assist in determining if the project being proposed does actually meet the intent of the EQIP program. Factors that determine the carbon sequestration effect of the planned treatment requires information that goes beyond the basic inventory data needed for practice needs, eligibility determination, and design. Landowners’ long term goals and objectives are needed to evaluate the use of this practice for carbon sequestration. The Basics of Carbon Sequestration: Trees sequester carbon by using photosynthesis to converting CO2 into woody and non woody plant material.
