Available in PDF, EPUB and Kindle. Book excerpt: S2In forestry, linear programming so far has been used primarily for analyzing economic problems of allocation. The technique has seldom, if ever, been applied to the solution of problems in mensuration, silviculture, or protection, possible because few foresters are familiar with its use and limitations. However, several common forestry problems appear to be amenable to linear programming. An approach to the solution of one of these problems, the estimation of maximum allowable timber yields, will be described in this paper.S3.

Download or read book Forest Regulation Harvest Scheduling and Planning Techniques written by William A. Leuschner and published by Wiley-Interscience. This book was released on 1990-06-21 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covers the regulation, harvest scheduling and planning techniques that are central to modern forest management. Traditional forest regulation is covered in detail, with assessments of such classical techniques as area and volume control as well as the neoclassical concepts of area-volume check and combined area and volume control. The sections on harvest scheduling examine mathematical programming models and solution techniques and their applications in scheduling problems; techniques using economic considerations, sloping demands and binary search are also discussed. There is a section on planning that includes a look at multiple objective techniques and FORPLAN, the USDA-Forest Service system for forest-wide planning. In addition, it contains useful information on linear programming methods and after- tax cashflow accounting.

Available in PDF, EPUB and Kindle. Book excerpt: The proposed action is to revise existing multiple use direction for the Mt. Hood National Forest portion of the Clackamas Planning Unit (353,779 acres) and 1000 acres of the Willamette National Forest portion of Mt. Jefferson Addition RARE II Area (6101). It does not establish direction for that portion of the Bull of the Woods not recommended for wilderness on the Willamette National Forest which is included within the Clackamas Planning Unit boundary. This area lies within Clackamas, Marion and Jefferson Counties, Oregon. The entire Planning Unit contains the Bull of the Woods (6098), Olallie (6099) and Mt. Jefferson Addition (6101) RARE II areas. The Planning Unit boundary has been extended to include the Willamette's portion of the identified roadless area 6101 and 6098. This statement has been prepared in accordance with interim regulations for the National Forest Management Act of 1976. A number of public issues and management concerns were identified at the beginning of the planning process. These centered around wilderness designation, fish habitat, Olallie Lake, old growth, reforestation, water quality, fire management, timber production, energy development and commercial service facilities at Ripplebrook.

This book was released on 1987 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The planning of harvests and management activities for forested lands has traditionally been done with either binary search or linear programming. Since both these techniques have some advantages over the other, they have remained in wide use. Hoganson and Rose (1984) have suggested a technique that theoretically could overcome some of the problems with binary search and linear programming while retaining many of their desirable characteristics. The technique uses shadow prices to guide the search for harvest levels in each period to meet certain goals. This study develops a new set of shadow price search procedures and makes a comparison between these three different harvest scheduling techniques. The comparisons were made by constructing a PASCAL computer model that gives the user a choice of solving harvest scheduling problems with either binary search or this new method, that will be referred to as "shadow price search". The computer program MIJSYC was used for the linear program formulations. Three example were solved by each of these methods. The results showed that linear programming and shadow price search produced solutions with similar harvest patterns among stands and present net worths that were close in value. Binary search found very different harvest patterns and consistently lower present net worths than either of the other two methods. Solution times for shadow price search were greater than binary search, but still less than linear programming solution times. Shadow price search seems a promising alternative to the traditional approaches for harvest scheduling problems with many timber stands and few constraints. For these problems, it's major drawback is occasional difficulty in converging on the optimal solution. Future research may solve this problem.
