Download or read book Environmental Modelling written by John Wainwright and published by John Wiley & Sons. This book was released on 2013-04-01 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simulation models are an established method used to investigate processes and solve practical problems in a wide variety of disciplines. Central to the concept of this second edition is the idea that environmental systems are complex, open systems. The authors present the diversity of approaches to dealing with environmental complexity and then encourage readers to make comparisons between these approaches and between different disciplines. Environmental Modelling: Finding Simplicity in Complexity 2nd edition is divided into four main sections: An overview of methods and approaches to modelling. State of the art for modelling environmental processes Tools used and models for management Current and future developments. The second edition evolves from the first by providing additional emphasis and material for those students wishing to specialize in environmental modelling. This edition: Focuses on simplifying complex environmental systems. Reviews current software, tools and techniques for modelling. Gives practical examples from a wide variety of disciplines, e.g. climatology, ecology, hydrology, geomorphology and engineering. Has an associated website containing colour images, links to WWW resources and chapter support pages, including data sets relating to case studies, exercises and model animations. This book is suitable for final year undergraduates and postgraduates in environmental modelling, environmental science, civil engineering and biology who will already be familiar with the subject and are moving on to specialize in the field. It is also designed to appeal to professionals interested in the environmental sciences, including environmental consultants, government employees, civil engineers, geographers, ecologists, meteorologists, and geochemists.
Download or read book Modeling the Regeneration and Early Stand Dynamics of Missouri Ozark Forests written by Lance Alan Vickers and published by . This book was released on 2015 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Projecting the effects of silvicultural choices on forest regeneration has traditionally been difficult. In an effort to improve upon this, a collection of empirical models based on leading hypotheses and theories of tree and stand development were constructed to simulate regeneration and early stand dynamics in Missouri Ozark forests. The stochastic models of establishment across a gradient of residual overstory density (Chapter 2) are consistent with the variable nature of the regeneration process. Linking establishment outcomes with models of annual height growth based on residual overstory density (Chapter 3) and size (Chapter 4) provides a powerful tool for both applied and empirical objectives. Quantitative interpretation of the regeneration process is as important as simulation of it. Developmental milestones for successful canopy recruitment were identified to improve evaluations of individual trees in even-aged stands during the regeneration process (Chapter 4). The reference chart methodology presented in Chapter 5 increases the inference obtainable from a single measurement by providing interpretation of individual tree development in the context of a variety of peer groups. Though imperfect, the combination of these models and tools should increase our understanding and ability to recreate the regeneration process, and as a result, the efficacy of our efforts to manipulate it.
Download or read book Sustainable Forest Management written by Hubert Hasenauer and published by Springer Science & Business Media. This book was released on 2006-03-29 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a strong movement towards uneven-aged forest management based on the idea that such stands increase or at least maintain soil fertility, increase biodiversity, and improve stand resilience. This shift in forest management practice renders existing yield tables increasingly unreliable. Among potential alternatives are tree growth models, because they predict the growth of each tree within a forest stand. This book summarizes three years of work related to the topic, carried out as a joint effort of leading tree growth modellers across Europe together with forest companies. By means of nine specific examples it demonstrates the problem-solving potential of tree growth modeling theory as required by various end-user groups.

Download or read book Modelling Forest Development written by Klaus von Gadow and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 222 pages. 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.

Download or read book Modelling Forest Growth and Yield written by Jerome K. Vanclay and published by Oxford University Press, USA. This book was released on 1994 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to growth modeling in mixed forests, with emphasis on the tropics. It is not intended as a 'how-to' manual with step-by-step instructions, as there is no single best way to model such forests. Rather it reviews different approaches, highlighting their strengths and limitations. It emphasizes empirical-statistical models rather than physiological-process type models, because of the proven utility of the former in forest management. Each chapter includes exercises that can be completed manually or on PC and spreadsheet. The book will serve as a reference manual for practitioners and as a text for advanced level students taking courses in forest modeling.
Download or read book Functioning and Management of European Beech Ecosystems written by Rainer Brumme and published by Springer Science & Business Media. This book was released on 2009-08-07 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperate forests cover large areas of Europe and perform a number of important functions such as the regulation of energy and matter, production of wood and other resources, and conservation of biodiversity and habitats; they also have special signi?cance in social and cultural contexts. Initiated in 1960s, the ?rst International Biological Program (IBP) focused on ‘‘the biological basis of productivity and human welfare. ’’ As the German contribution to the IBP, ecosystem research has been carried out since 1966 in the Solling area (Ellenberg H. , Ecological Studies 2, 1971), an upland region in Northwest Germany. This study provided clear evidence that the stability of forest ecosystems was threatened by the high inputs of at- spheric pollutants. This promoted many interdisciplinary research programs which were coordinated by Prof. Dr. Bernhard Ulrich and the Forest Ecosystems Research Center of the University of Go ̈ttingen. This involved, in addition to the Solling site, the establishment of two other sites for long-term monitoring of ecosystem pro- ̈ cesses. The two contrasting sites were established in 1980 at Gottinger Wald on base-rich calcareous soil and in 1989 at Zierenberg on volcanic soil. These projects were funded initially by the Federal Ministry of Research and Technology (BMBF) as interdisciplinary projects under the titles: ‘‘Conditions of Stability of Forest Ecosystems’’ (1989–1993), and ‘‘Dynamics of Forest Ecos- tems’’ (1993–1998). The primary goal of these studies was to quantify the ecolo- cal condition of forests in a changing environment and element ?uxes.
