Handbook Of Field And Office Problems In Forest Mensuration Classic Reprint

Excerpt from Handbook of Field and Office Problems in Forest Mensuration The problems in this handbook were originally prepared as an aid to the laboratory instruction in forest mensuration at the University of Washington, and were first published by the authors in 1915. Numerous changes and additions were made in this edition, particularly with reference to making them more generally useful to the practical field and office men and more generally applicable to all sections of the country. In the few instances where they are not applicable they can readily be made so by slight modifications at the instance of the instructor in charge. In each problem the forms for recording and for working up the data have been definitely indicated. It has been found that this will result in greater uniformity and better standards of comparison for the work of the individual students. Although different schools are using forms that differ in some of the details they can readily be made applicable by adopting form numbers to coincide with those adopted in this handbook. These forms are illustrated in the Appendix on pages 90 to 97. In the preparation of the handbook the object has not been to present a complete series of problems covering the entire field of forest mensuration, but rather a series of carefully selected type exercises which may be used as practical illustrations to supplement the recitation and text-book work. A number of the newer methods recently developed but not yet thoroughly established have been purposely omitted. References to various new methods will be found in the Appendix, in connection with the Bibliography. The authors have included only problems of standard character. It is hoped that the value of the handbook will be due as much to what is omitted as to what is actually included. Experience has shown that a few fundamental type exercises, carefully worked out in the field and laboratory, and their relation to associated problems then brought out in class-room discussions will give the student a more thorough grounding in the subject than a multitude of exercises hurriedly worked over but not assimilated. A second feature sought in these problems is the elimination of an undue amount of duplication in clerical work. The function of a university is to teach the how and the wherefore. Our time is too limited to use more than a reasonable amount of it for drill work, and it has been our experience that clerical drudgery often obscures the fundamental object of an exercise.

Forest mensuration – the science of measurement applied to forest vegetation and forest products – holds value for basic ecology as well as sustainable forest management. As demands on the world’s forests have grown, scientists and professionals are increasingly called on to quantify forest composition, structure, and the goods and services forests provide. Grounded in geometry, sampling theory, and ecology as well as practical field experience, forest mensuration offers opportunities for creative problem solving and critical thinking. This fifth edition of the classic volume, Forest Mensuration, includes coverage of traditional and emerging topics, with attention to SI and Imperial units throughout. The book has been reorganised from the fourth edition to better integrate non-timber and ecological aspects of forest mensuration at the tree, stand, forest, and landscape scales throughout. The new edition includes new chapters that specifically address the integration of remotely sensed data in the forest inventory process, and inventory methods for dead and downed wood. One unifying theme, not only for traditional forestry but for the non-timber inventory and for remote sensing, is the use of covariates to make sampling more efficient and spatially explicit. This is introduced in the introductory chapter on statistics and the chapter on sampling designs has been restructured to highlight this approach and lay the foundation for further learning. New examples will be developed throughout the textbook with an emphasis on current issues and international practice. Students in applied forestry programs will find ample coverage of forest products and timber inventory, while expanded material on biodiversity, biomass and carbon inventory, downed dead wood, and the growing role of remote sensing in forest assessment will be valuable to a broader audience in applied ecology.

Forestry is the science of creating, managing, planting, using, conserving, and repairing forests, woodlands. This book gives a brief overview of the history of Forestry worldwide with an emphasis on the United States and Europe. An author tries to analyze the facts and empirical data on the historical development of forestry to have a basis for present-day solutions and advances in this domain.
