Book excerpt: The purpose of this study is to examine the basic questions facing the manager interested in practicing even-aged forest management and to explain and evaluate the various analytical tools historically, currently, or potentially useful in answering the questions. Evaluation criteria will include: the way a particular method characterizes the stand or forest; the growth and yield information requirements of the method; the computational burden association with the method; the flexibility of the method as to the form and complexity of the solution; and other pertinent considerations

Book excerpt: This textbook offers a detailed overview of the current state of knowledge concerning the ecology and management of compositionally and structurally diverse forests. It provides answers to central questions such as: What are the scientific concepts used to assess the growth, dynamics and functioning of mixed-species forests, how generalizable are they, and what kind of experiments are necessary to develop them further? How do mixed-species stands compare with monocultures in relation to productivity, wood quality, and ecological stability in the face of stress and disturbances? How are the effects of species mixtures on ecosystem functioning influenced by the particular species composition, site conditions, and stand structure? How does any over- or underyielding at the forest-stand level emerge from the tree and organ level, and what are the main mechanisms behind mixing effects? How can our current scientific understanding of mixed-species forests be integrated into silvicultural concepts as well as practical forest management and planning? Do the ecological characteristics of mixed-species stands also translate into economic differences between mixtures and monocultures? In addition, the book addresses experimental designs and analytical approaches to study mixed-species forests and provides extensive empirical information, general concepts, models, and management approaches for mixed-species forests. As such, it offers a valuable resource for students, scientists and educators, as well as professional forest planners, managers, and consultants.

Download or read book Dynamics Silviculture and Management of Mixed Forests written by Andrés Bravo-Oviedo and published by Springer. This book was released on 2018-11-26 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: The capacity of mixed forests to mitigate climate change effects by increasing resilience and lowering risks is pinpointed as an opportunity to highlight the role of tree species rich forests as part of complex socio-ecological systems. This book updates and presents the state-of-the-art of mixed forest performance in terms of regeneration, growth, yield and delivery of ecosystem services. Examples from more than 20 countries in Europe, North Africa and South America provide insights on the interplay between structure and functionining, stability, silviculture and optimization of management of this type of forests. The book also analyses the role of natural mixed forests and mixed plantations in the delivery of ecosystem services and the best modelling strategy to study mixed forest dynamics. The book is intended to serve as a reference tool for students, researchers and professionals concerned about the management of mixed forests in a context of social and environmental change.

Available in PDF, EPUB and Kindle. Book excerpt: Although the majority of the world’s forest ecosystems are dominated by uneven-sized multi-species stands, forest management practice and theory has focused on the development of plantation monocultures to maximize the supply of timber at low cost. Societal expectations are changing, however, and uneven-aged multi-species ecosystems, selectively managed as Continuous Cover Forestry (CCF), are often believed to be superior to monocultures in addressing a wide range of expectations. This book presents methods which are relevant to CCF management and planning: analysing forest structures, silvicultural and planning, economic evaluation, based on examples in Europe, Asia, Africa and North and South America.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Tropical forest plantations play an important role in meeting global wood demand. While research has highlighted the ecological potential of mixed-species plantations, studies on the economic viability and management of such plantations are largely missing in the context of tropical plantation forestry. In this study, we estimated the economic potential and optimized the management of commercial mixed-species plantations of four tree species native to Central America (Dalbergia retusa, Dipteryx oleifera, Hieronyma alchorneoides, and Vochysia guatemalensis) and Teak (Tectona grandis). We combined the forest growth model 3-PGmix and detailed economic data for two plantation sites in Costa Rica to optimize the management of 11 different mixtures using a genetic optimization algorithm. We found that several of the modeled mixed-species stands can be highly profitable with net present values (NPV) up to 4821.2 USD/ha at an 8% discount rate, and internal rates of return up to 17% (under excellent site conditions). This indicates that the most profitable mixtures (e.g. of V. guatemalensis-D. oleifera or T. grandis-D. oleifera on excellent sites) could compete economically with conventional monoculture plantations such as Teak monocultures. Further, mixed stands can be managed based on the same simple even-aged management approaches currently applied in monoculture plantations if the specific management parameters are adapted. The optimized management parameters also lead to improved NPV of the modeled stands under alternative valuation assumptions but are site-specific. In the present study, we only considered financial benefits from timber production. However, establishing mixed-species plantations in the tropics could provide a wide range of ecosystem services including climate change mitigation and biodiversity protection
Download or read book Multiaged Silviculture written by Kevin O'Hara and published by OUP Oxford. This book was released on 2014-08-28 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest scientific and management information on multiaged silviculture, an emerging strategy for managing forestry systems worldwide. Over recent decades, forest science and management have tended to emphasize plantation silviculture. Whilst this clearly meets our wood production needs, many of the world's forests need to be managed far less intensively and more flexibly in order to maintain their natural ecosystem functions together with the values inherent in those processes. Developing multiaged management strategies for these complex forest ecosystems represents a global challenge to successfully integrate available science with sustainable management practices. Multiaged Silviculture covers the ecology and dynamics of multiaged stands, the management operations associated with regeneration, tending, and stocking control, and the implications of this strategy on production, genetic diversity, and stand health. It is primarily aimed at graduate level students and researchers in the fields of forestry and silviculture, but will also be of relevance and use to all professional foresters and silviculturists.
