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.

Available in PDF, EPUB and Kindle. Book excerpt: Forestry is one of the most important foundations of the Scandinavian economies. Sustainable Forestry in Southern Sweden: The SUFOR Research Project reviews the findings from the eight-year research program first launched in 1997 that searched for applicable ways to maintain sustainable forestry in the region. Respected scholars and experts discuss ways to bridge the chasm separating the world of research with the world of trade and industry. Biodiversity, the impact of humans, environmental conditions, and other facets of sustainability are all presented and discussed in detail. The book is extensively referenced and includes several tables to ensure clarity of data.

Download or read book Continuous Cover Forestry written by Timo Pukkala and published by Springer Science & Business Media. This book was released on 2011-10-14 with total page 298 pages. 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.
Download or read book Ecology of Central European Forests written by Christoph Leuschner and published by Springer. This book was released on 2017-09-22 with total page 998 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook in two volumes synthesises our knowledge about the ecology of Central Europe’s plant cover with its 7000-yr history of human impact, covering Germany, Poland, the Netherlands, Belgium, Luxembourg, Switzerland, Austria, Czech Republic and Slovakia. Based on a thorough literature review with 5500 cited references and nearly 1000 figures and tables, the two books review in 26 chapters all major natural and man-made vegetation types with their climatic and edaphic influences, the structure and dynamics of their communities, the ecophysiology of important plant species, and key aspects of ecosystem functioning. Volume I deals with the forests and scrub vegetation and analyses the ecology of Central Europe’s tree flora, whilst Volume II is dedicated to the non-forest vegetation covering mires, grasslands, heaths, alpine habitats and urban vegetation. The consequences of over-use, pollution and recent climate change over the last century are explored and conservation issues addressed.
Download or read book Forest Tree Breeding in Europe written by Luc E Pâques and published by Springer Science & Business Media. This book was released on 2013-05-31 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest tree breeding has been ongoing for more than 70 years across Europe. It has successfully generated improved varieties for the major economical forest tree species. They are part of the present European forestry landscape and largely contribute to intensive wood production and other forest activities. In this book, we describe the state-of-art of breeding for the main forest tree species. We provide a comprehensive, unique and up-to-date overview of the major scientific results and breeding achievements gathered from the many programmes scattered across Europe. The book is divided into 10 chapters, each as a monograph corresponding to a species or group of species Abies spp., (Larix spp., Picea abies, Picea sitchensis, Pinus sylvestris, Pseudotsuga menziesii, and Mediterranean pines; Acer pseudoplatanus, Fraxinus excelsior, and Prunus avium). Each of them is written by a group of experts and focuses on the distribution and economical importance of the species; motivation for breeding and breeding objectives; intraspecific genetic variability, breeding populations and breeding strategy; forest reproductive material deployment including mass-propagation and, prospects and perspectives for joint research and breeding. The book is a unique and up-dated source of information for students, researchers and professionals interested in the genetics and domestication of forest tree species.
