Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to improve the understanding of forest dynamics and the sustainable management of forest ecosystems. How do tree crowns, trees or entire forest stands respond to thinning in the long term? What effect do tree species mixtures and multi-layering have on the productivity and stability of trees, stands or forest enterprises? How do tree and stand growth respond to stress factors such as climate change or air pollution? Furthermore, in the event that one has acquired knowledge about the effects of thinning, mixture and stress, how can one make that knowledge applicable to decision-making in forestry practice? The experimental designs, analytical methods, general relationships and models for answering questions of this kind are the focus of this book. Given the structures dealt with, which range from plant organs to the tree, stand and enterprise levels, and the processes analysed in a time frame of days or months to decades or even centuries, this book is directed at all readers interested in trees, forest stands and forest ecosystems. This work has been compiled for students, scientists, lecturers, forest planners, forest managers, and consultants.

Book excerpt: This study modelled the risk of fire at the stand and forest level to aid management decisions on the effect of such occurrences on annual allowable cut and future timber supplies; determined the frequency of large-scale insect and disease occurrences, and derived a model to assess their impact on the present and future forest yields; and tested, reviewed, and modified the fire, insect and disease, and other risk factor models for application over boreal forest ecoregions in western Canada. The program involved probabilistic (a preliminary version of the FOrestry RIsk Model (FORIM) based on Hinton leasehold and East Slopes fire risk data), deterministic (FORMAN model selected, modified, and tested for impacts in the Footner Lake and the Peace River volume sampling regions in northern Alberta), and dynamic (Markov decision support model applied to optimal forest management strategies for the Peace River and Footner Lake forests in northwestern Alberta) modelling approaches to give a comparative assessment of their merits.

Available in PDF, EPUB and Kindle. Book excerpt: In an lUlffianaged woodland, forest development follows a succession of periods of undisturbed natural growth, interrupted by intermediate loss or damage of trees caused by fire or wind or other natural hazards. In a managed woodland, the most important periodic disturbances are the thinning operations, which are often carried out at regular intervals and which usually have a significant effect on the future evolution of the resource. Thus, a realistic model of forest development includes both natural growth and thinnings. The key to successful timber management is a proper understanding of growth processes, and one of the objectives of modelling forest development is to provide the tools that enable foresters to compare alternative silvicultural treatments. Foresters need to be able to anticipate the consequences of a particular thinning operation. In most cases, total timber volume is not a very appropriate measure for quantifying growth or yields, or changes caused by thinning operations. Yield in economic terms is defined by the dimensions and quality attributes of the harvestable logs, and estimating timber products is a central issue of production-oriented growth and yield research. Introduction 2 Growth modelling is also an essential prerequisite for evaluating the consequences of a particular management action on the future development of an important natural resource, such as a woodland ecosystem.

Book excerpt: This report briefly describes the growth & yield prediction systems currently produced by the British Columbia Ministry of Forests. Only those systems that generate estimates of stand volume are considered; site index curves, individual tree volume equations, & other important growth & yield tools are not described. Relevant background information is included, including the history of growth & yield prediction, classification of prediction systems, and system characteristics. Simple mathematical expressions are provided to describe the systems used for unmanaged stands (site class system, variable density yield projections, site index system) and managed stands (the Tree & Stand Simulator). The final sections contain examples illustrating the use of the systems within the Ministry and a review of future development of such systems. Includes glossary.

This book was released on 2010 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine if control charts are an effective tool to identify trends in forest growth and yield model accuracy. Accurate forest growth and yield models are important for projecting future forest composition. However, environmental factors have the potential to make forest growth models created from historic data inaccurate. Control charts in this study determine if forest growth predictions fall within confidence limits established for historic growth at a number of points in time. Two data sets were used in this study: the first was a Continuous Forest Inventory (CFI) from three tracts at the University of Tennessee Cumberland Research Station and the second data set was Forest Inventory and Analysis data collected by the U.S. Forest Service. The CFI plots represented a stand level data set measured every 5 years from 1962-1977 and revisited for a re-measurement in 2009. The FIA plots were a regional data with subsets of plots measured annually from 1999-2008. The FIA data set was limited to plots of the oak/hickory forest type from Tennessee, Alabama, and Georgia. Two forest growth and yield models were used to predict growth: (1) WinYield and (2) Forest Vegetation Simulator (FVS). The two different data sets were used with both FVS and WinYield to evaluate control charts using different models ad at different spatial and temporal scales. The data sets were also subset by site index, stand age, stocking percent, aspect, and species composition to determine if control charts could identify changes in model accuracy for forests subjected to different growing conditions. The CFI and FIA data had short growth predictions and control charts indicated that there were no trends affecting accuracy. The CFI data also had a long growth prediction of 32 years and the control charts found that the predictions using WinYield and FVS were inaccurate, indicating that there may be a trend causing inaccuracy in the model.

Available in PDF, EPUB and Kindle. Book excerpt: S2Describes a species-specific, distance-independent individual-tree diameter growth model for the Northeastern United States. Diameter growth is predicted in two steps using a two parameter, sigmoidal growth function modified by a one parameter exponential decay function with species-specific coefficients. Coefficients are presented for 28 species groups. The model accounts for variability in annual diameter growth due to species, tree size, site quality, and the tree's competitive position within the stand. Model performance is evaluated using the mean predicted error and the root mean square error. Results are presented for the calibration data and an independent validation data set. The model has been, incorporated into NE-TWIGS, a computerized forest growth model for the Northeastern United States.S3.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Forest Growth Modelling and Prediction, Vol. 1: Proceedings of the Iufro Conference, August 23-27, 1987, Minneapolis, Minnesota Munro's (1974) paper on forest growth models is a starting point for a fresh look at growth simulation. His discussion of modelling philosophy set the stage for much recent progress, but seems best remembered for its classification of growth models which singles out one of several differences among models-whether it is a single-tree or a whole-stand model. In this paper, we suggest emphasis on the forest condition being modelled and on the purpose of the model. We also examine some terms that are frequently used in forest growth and yield modelling. Finally, we look at some problems often encountered in developing computer simulations. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 1996-07-30 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dipterocarp forests of South-East Asia constitute a dominant component of the world's tropical forests. As such, they are intertwined with a Pandora's box of problems that have plagued the world for decades; Over- and underdevelopment, poverty, hunger, population growth, exploitation of natural resources, environmental degradation, loss of biodiversity, the debt crisis and, of late, climate change. The world community has responded to the crucial role of these forests and the dangers facing them with funds, and a myriad of programmers, projects, institutions, conferences and networks. Apparently neither a lack of knowledge nor finance constrains the dissipation of sustainable management practices: the fate of the world's Dipterocarp forests will certainly depend on the involvement of scientists from many nations and disciplines, but will perhaps ultimately, rest with local policymakers, forest administrators and line foresters. Unfortunately, these two groups rarely share realms, readings or reasoning: practical foresters, invariably very involved with the challenges of day-to-day forest management in remote, isolated environments, may long remain oblivious to scientific developments. Traditionally though they do find solutions to problems, gain deep insights into forest responses and practical constraints, and sometimes even report in semi-obscure publications, which rarely reach the scientific circuit.The editors of the book, both experienced forest and soil scientists and practical forest managers, have attempted to bridge the gap between the realms of forest science and practice in Dipterocarp ecology, management and utilization.
