Download or read book Sampling Theory for Forest Inventory written by Pieter G.de Vries and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest inventory may be defined as the technique of collecting, evaluating and presenting specified information on forest areas. Because of the generally la~ge extent of forest areas, data are usually collected by sampling, i.e. by making observations on only part of the area of interest. As there are many different sampling methods (e.g. Appendix 1), a choice must first be made as to which method suits the given field and financial circumstances best. On completion of the sampling procedure, the numerous data collected have next to be condensed to manageable representative quantities. Finally, from these quantities, inferences about the situation in the entire forest area are made, preferably accompanied by an indication of their reliability. This book is intended for students who want to know the whepefope of the sampling techniques used in forest inventory. The danger of lack of knowledge is a blind following of instructions and copying statistical formulae, or, even worse, feeding data into a computer loaded with a program that is said to print out the required information. In serious persons, such approaches may leave a feeling of dissatisfaction or even of professional incompetence, be cause of inability to direct or evaluate the procedure critically. If a student tries to improve his or her situation, he/she will find that the few existing forest inventory textbooks, though some with merit, either use confusing statistical symbols or do not adequately cover theoretical principles.

Download or read book Principles of National Forest Inventory Methods written by Allan Sims and published by Springer Nature. This book was released on 2022-09-07 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Monograph explains the statistical theory behind the National Forest Inventory (NFI) data collection and compares different methods for modelling and inventory design. The author also explains how natural uncertainty in measurement and modelling can affects the results. Forests, as dynamic systems, are influenced by many unpredictable factors over time. Therefore, readers can use this book to develop the right framework of expectations, when using NFI data. The chapters give an outlook on traditional methods like sample plots, but also consider newer approaches like remote sensing. By merging these different techniqes, NFI datasets can become more reliable and facetted. One of the most contemporary developments in the field, is the use of continuous plots that offer live data at all times. Whether this data should be open to the public, is another discussion point that the author addresses. Offering a perspective from Estonia, readers will find practical examples for all discussed methods. This bridge from theory to practice, makes the volume a useful resource for scientists and decision makers in the forestry sector.
Download or read book National Forest Inventories written by Erkki Tomppo and published by Springer Science & Business Media. This book was released on 2009-12-02 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest inventories throughout the world have evolved gradually over time. The content as well as the concepts and de?nitions employed are constantly adapted to the users’ needs. Advanced inventory systems have been established in many countries within Europe, as well as outside Europe, as a result of development work spanning several decades, in some cases more than 100 years. With continuously increasing international agreements and commitments, the need for information has also grown drastically, and reporting requests have become more frequent and the content of the reports wider. Some of the agreements made at the international level have direct impacts on national economies and international decisions, e. g. , the Kyoto Protocol. Thus it is of utmost importance that the forest information supplied is collected and analysed using sound scienti?c principles and that the information from different countries is comparable. European National Forest Inventory (NFI) teams gathered in Vienna in 2003 to discuss the new challenges and the measures needed to get data users to take full advantage of existing NFIs. As a result, the European National Forest Inventory Network (ENFIN), a network of NFIs, was established. The ENFIN members decided to apply for funding for meetings and collaborative activities. COST– European Cooperation in Science and Technology - provided the necessary ?n- cial means for the realization of the program.
Download or read book Forest Inventory Permanent Sample Plot Field Measurement Methods and Specifications a System of Permanent Sample Plots Randomly Located Throughout the Forests of the Province of Nova Scotia written by Nova Scotia. Forestry Division. Inventory Section and published by . This book was released on 2002 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Forest Inventory Permanent Sample Plot Program established forest inventory plots (FIPs) at random locations throughout the province from 1965 to 1970 to determine growth & mortality of the natural forest. The FIP program was expanded in 1998 to measure more plots & more variables to help the province report on a wider range of criteria & indicators and to permit better tracking of some aspects of forest biodiversity & sustainability. This document presents specifications developed for the re-measurement of the current FIPs and procedures for establishing over two thousand new FIPs. It includes information on the selection process for new FIPs, the data to be collected, measurement methods, and data reporting. Appendices include a list of tree & shrub species names, copies of worksheets & tables for use in the field, and procedures for using March II geographic positioning system units.

Available in PDF, EPUB and Kindle. Book excerpt: This book has been developed as a forest inventory textbook for students and could also serve as a handbook for practical foresters. We have set out to keep the mathematics in the book at a fairly non-technical level, and therefore, although we deal with many issues that include highly sophisticated methodology, we try to present first and foremost the ideas behind them. For foresters who need more details, references are given to more advanced scientific papers and books in the fields of statistics and biometrics. Forest inventory books deal mostly with sampling and measurement issues, as found here in section I, but since forest inventories in many countries involve much more than this, we have also included material on forestry applications. Most applications nowadays involve remote sensing technology of some sort, so that section II deals mostly with the use of remote sensing material for this purpose. Section III deals with national inventories carried out in different parts of world, and section IV is an attempt to outline some future possibilities of forest inventory methodologies.

Available in PDF, EPUB and Kindle. Book excerpt: Continuing a tradition of excellence spanning over forty years, the Fifth Edition of Forest Measurements supplies forestry students at all levels with the concepts and methods they need for future success. The authors present timber measurement techniques applicable to any tree inventory regardless of management objectives. Assuming only some background in algebra and plane trigonometry, basic statistical concepts are included, ensuring that even introductory students benefit from the book’s concise explanations. Thorough coverage of sampling designs, land measurements, tree measurements, forest inventory field methods, and growth projections ensures utility for foresters throughout their education and beyond. Chapters on aerial photographs and GIS introduce readers to these powerful measurement tools, and the concluding chapter expands the techniques discussed to encompass other natural resources such as rangelands, wildlife, and water. Exceptionally readable and clear, the book includes many photographs and illustrations, numerous numerical examples, and a bibliography to enhance the reader’s understanding of the material.
