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.

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 423 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.

Book excerpt: First Published in 1998. This important work looks at an alternative approach to resource production systems, taking the view that many environmental problems associated withconventional resource management are avoidable if we work with nature, instead of trying to dominate it. Jordan argues that achieving sustainability in production systems is best accomplished by encouraging a change in the relationship between humans and nature-from one of exploitation through control to one of sustainability through cooperation.

Download or read book Volume Yield to Mid rotation in Pure and Mixed Sown Stands of Pinus Sylvestris and Picea Abies in Sweden written by Bengt Jonsson and published by . This book was released on 2001 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume yield to mid-rotation in pure and mixed sown stands of Scots pine and Norway spruce was investigated in an experiment in central Sweden. The 43-year-old stands were situated on a 7-ha site and were treated and inventoried at the time of establishment, then at intervals in the life of the stands, to give results at half-rotation age. The dynamics of the mixed stands implied a favourable ecological mixed-stand effect on the height growth of spruce in early development and before crown closure. Even at this stage, pines were taller than spruces, but height was not influenced by admixture with spruce. Pines continued to grow faster than spruces in both height and diameter, resulting in dense mixed stands with dominant pines and co-dominant or suppressed spruces. Diameter of pines was increased by weaker competition for nutrients, while weaker competition for light led to a lower height of dominant pines in mixed stands than in pure pine stands. The results indicate a slight etiolation effect of competition for light in the crown layer. Total volume yield was higher in mixed stands than the mean yield in pure stands of pine and spruce, mainly owing to the dominance of pine in mixed stands. However, it was lower in mixed stands than in pure pine stands. The growth dynamics to the present time indicates that, after a slow start, volume growth of spruce increases remarkably in pure stands and increases slightly in mixed stands. while volume growth of pine began early and is culminating.

This book was released on 2012-04-27 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing upon a wealth of past research and results, this book provides a comprehensive summary of state-of-the-art methods for empirical modeling of forest trees and stands. It opens by describing methods for quantifying individual trees, progresses to a thorough coverage of whole-stand, size-class and individual-tree approaches for modeling forest stand dynamics, growth and yield, moves on to methods for incorporating response to silvicultural treatments and wood quality characteristics in forest growth and yield models, and concludes with a discussion on evaluating and implementing growth and yield models. Ideal for use in graduate-level forestry courses, this book also provides ready access to a plethora of reference material for researchers working in growth and yield modeling.

Download or read book Dendroecology written by Mariano M. Amoroso and published by Springer. This book was released on 2017-12-12 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dendroecologists apply the principles and methods of tree-ring science to address ecological questions and resolve problems related to global environmental change. In this fast-growing field, tree rings are used to investigate forest development and succession, disturbance regimes, ecotone and treeline dynamics and forest decline. This book of global scope highlights state-of-the-science dendroecological contributions to paradigm-shifts in our understanding of ecophysiology, stand dynamics, disturbance interactions, forest decline and ecosystem resilience to global environmental change and is fundamental to better managing our forested ecosystems for the full range of ecosystem goods and services that they provide.
Download or read book Behavioural Mechanisms of Food Selection written by Roger N. Hughes and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 887 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavioural Mechanisms of Food Selection examines animals belonging to diverse trophic groups, from carnivores, herbivores, micro-algal grazers, to filter-feeders and detritus-feeders. In the past Optimal Foraging Theory has been applied to all these groups, but in different ways and in disci plines that rarely overlap. Here concepts and developments hitherto scattered in the literature are drawn together. This uniquely broad synthesis captures the state of the art in the study of diet selection and prescribes new objectives in theoretical development and research.
