Book Synopsis Forest Biomass and Carbon by : Gopal Shukla
Download or read book Forest Biomass and Carbon written by Gopal Shukla and published by BoD – Books on Demand. This book was released on 2018-11-14 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests grow and their biomass increases; they absorb carbon from the atmosphere and store it in plant tissue. Understanding the biomass of forest vegetation is essential for determining the storage of carbon in the dominant tree component and computing carbon cycling at a regional as well as global level. This book consisting of five chapters will give a comprehensive understanding of biomass production vis-à-vis carbon storage in relation to litter and nutrient dynamics of the forest by analyzing the mode and magnitude of biomass production and carbon storage as a function of various silvicultural factors.
Book Synopsis An Empirical Analysis of Adaptability to Climate Change and Risk in Forest Management by :
Download or read book An Empirical Analysis of Adaptability to Climate Change and Risk in Forest Management written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation provides a quantitative analysis of the adaptability in forest management to future risks using existing data describing pine growth and management across a range of conditions in the southern U.S. Future risks include gradual climatic change, catastrophic events, price and yield risks. The adaptive options considered include rotation ages, thinning ages, thinning intensity and frequency, planting density and stand stocking. Using a bio-economic model approach, two empirical yield models based on U.S. Forest Service FIA data are integrated with an extended Faustmann and a Real Options optimization models respectively. Simulation results are obtained across risk categories and model types. Marginal and joint effects of risk are derived and comparisons between different integrated models are made. Forest managers' optimal decisions in response to risk are found to be sensitive to the set of adaptive options. The ÃØâ'ƠÅ"standardÃØâ'ƠÂ optimal rotation results do not necessarily hold if stand density control and thinning options are considered. The impacts of discrete catastrophic events on forest management adaptation and welfare are found to be more important than the gradual climate change impact. Gradual climate change within the range of Hadley 3 scenarios does not lead to significant changes in optimal rotation age, stand density or thinning ages but the change in forest rents may be significant. Depending on the impact of climate change on agriculture rent, we would expect more adaptations at the extensive margin (land use change) than the intensive margin (silvicultural intensity).
Book Synopsis Modelling Forest Development by : Klaus von Gadow
Download or read book Modelling Forest Development written by Klaus von Gadow and published by Springer Science & Business Media. This book was released on 2001-11-30 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. 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. One of the outstanding features of this book is its inclusion of thinning models at varying levels of resolution and consideration of differences in foresters' tree marking behaviour. Other interesting aspects include regional resource forecasting approaches, generalized stem taper functions, generalized diameter-height relations, new ways of describing and reproducing forest spatial structures, crown modelling and iterative competition modelling. Worked examples and code are provided where appropriate. The intended readership is graduate students.
Book Synopsis Models of Tree and Stand Dynamics by : Annikki Mäkelä
Download or read book Models of Tree and Stand Dynamics written by Annikki Mäkelä and published by Springer Nature. This book was released on 2020-03-17 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is designed to be a textbook for university students (MSc-PhD level) and a reference for researchers and practitioners. It is an introduction to dynamic modelling of forest growth based on ecological theory but aiming for practical applications for forest management under environmental change. It is largely based on the work and research findings of the authors, but it also covers a wide range of literature relevant to process-based forest modelling in general. The models presented in the book also serve as tools for research and can be elaborated further as new research findings emerge. The material in the book is arranged such that the student starts from basic concepts and formulations, then moves towards more advanced theories and methods, finally learning about parameter estimation, model testing, and practical application. Exercises with solutions and hands-on R-code are provided to help the student digest the concepts and become proficient with the methods. The book should be useful for both forest ecologists who want to become modellers, and for applied mathematicians who want to learn about forest ecology. The basic concepts and theory are formulated in the first four chapters, including a review of traditional descriptive forest models, basic concepts of carbon balance modelling applied to trees, and theories and models of tree and forest structure. Chapter 5 provides a synthesis in the form of a core model which is further elaborated and applied in the subsequent chapters. The more advanced theories and methods in Chapters 6 and 7 comprise aspects of competition through tree interactions, and eco-evolutionary modelling, including optimisation and game theory, a topical and fast developing area of ecological modelling under climate change. Chapters 8 and 9 are devoted to parameter estimation and model calibration, showing how empirical and process-based methods and related data sources can be bridged to provide reliable predictions. Chapter 10 demonstrates some practical applications and possible future development paths of the approach. The approach in this book is unique in that the models presented are based on ecological theory and research findings, yet sufficiently simple in structure to lend themselves readily to practical application, such as regional estimates of harvest potential, or satellite-based monitoring of growth. The applicability is also related to the objective of bridging empirical and process-based approaches through data assimilation methods that combine research-based ecological measurements with standard forestry data. Importantly, the ecological basis means that it is possible to build on the existing models to advance the approach as new research findings become available.

Download or read book Development of an Empirical Prognosis Model for Forest Growth Based on the Yunnan Forest Continuous Inventory written by and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background and objective of the research study The objective of this research study is the development of a forest stand growth model for the forests in the province Yunnan of southern China. The forest growth model is based on a position independent single tree growth modelling concept. The background for this objective is given by the heavy land use in the Yunnan province, leading to destruction of forest ecosystems, erosion and endangered wildlife. In addition the forest must meet the requirements of a growing and economically developing society that needs land for the farmers, timber for the industry and water for drinking. A forest stand growth model shall enable decision makers in forestry and politics to analyse decision alternatives on a sound empirical data basis and with statistically validated methods. Data from the Yunnan Forest Continuous Inventory Yunnan belongs to the southernmost provinces of China with a total area of about 390,000 km2. Since 1978 the forests of this province are monitored by the Yunnan Forest Continuous Inventory with survey years in 1978, 1988, 1992, 1997 and 2002. For this research study data from the three prefectures Simao, Lincang and Xishuangbanna with 21 counties. These inventories provide a huge data pool from the assessments on more than 800 inventory plots on forest land. Single tree information is available for tree diameter DBH as well as tree heights, stem numbers on the plots and tree species. Roughly 80,000 single tree DBH records are available and more than 2,000 single tree DBH and height increment records from subsequent inventories. In addition plot specific site information like elevation, slope, aspect, soil depth and soil type is available too, and on county level even climatic data are accessible like mean annual temperature, annual precipitation, evaporation and radiation. Developing a position independent single tree growth model Beneath the objective to build a forest stand growth model some additional obj.

Book Synopsis Forest Dynamics, Growth and Yield by : Hans Pretzsch
Download or read book Forest Dynamics, Growth and Yield written by Hans Pretzsch and published by Springer Science & Business Media. This book was released on 2009-06-19 with total page 670 pages. 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.
