Forest Tree Breeding In Europe

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.

In the context of global environmental change, European forests are expected to fulfil a broad range of functions, including the supply of raw materials to the bioeconomy, biodiversity preservation, and the provision of ecological services. Given fast progress in applied genetics, the selection and diffusion of genetically improved forest reproductive material (FRM) has a role to play towards the achievement of those goals. We therefore investigate EU forest tree breeding conceived as an innovative activity on the basis of four case studies (eucalyptus in Portugal, maritime pine in France, and Norway spruce in Sweden and Finland), using a conceptual framework combining the innovation system approach and the economics of innovation. The genetic progressed achieved for each of those species has been regular since the beginning of tree breeding activities. Despite that, we identify both systemic issues and market failures that hinder FRM genetic innovation and make the prospects of a forest tree breeding revolution unlikely. While the innovation systems in the studied countries are structurally sound, the private investment in breeding activity is limited and observed only in some cases. This, in turn, is explained by incentive problems limiting both supply and demand of genetically improved FRM. On the demand side forest owners value improved FRM only moderately because of long lags between plantation and harvest, imperfect knowledge of the potential gains from adoption of genetically improved FRM, and risk aversion. On the supply side, returns to investments in genetic improvement are heavily constrained by the slowness of the breeding process, capacity constraints related to FRM production, limited demand pull and regulatory uncertainty. Those incentive problems are partially overcome in path-dependent situations where the industry is vertically integrated, from FRM production to wood processing, as observed in the case of eucalyptus in Portugal or Norway spruce in Sweden. In the other cases, public support for breeding programmes is paramount. Therefore, a better use of FRM genetic improvement to address the challenges faced by European forests requires efforts to communicate the benefits - pecuniary or otherwise - of genetically improved trees to forest owners, to compensate forest owners for the provision of environmental externalities, and to make future regulations more predictable.

Monograph represents short reviews on the genetics and breeding of introduced to Europe forest tree species. The management of tree species non-native to European geographical regions has a long tradition within forestry management practice. Their introduction to Europe (initially focused on growing tree species) dates back to the 18th century when enormous demands were being made on natural resources to sustain the on-going industrialization of Europe. Today issues of biomass production and C sequestration as well as the question of whether these species could increase the adaptive capacity of forests to long-term climate change patterns have fueled a growing interest in non-native tree species in Europe.

Ecology and Conservation of Forest Birds is a unique review of current understanding of the relationships between forest birds and their changing environments. Large ecological changes are being driven by forest management, climate change, introduced pests and pathogens, abiotic disturbances, and overbrowsing. Many forest bird species have suffered population declines, with the situation being particularly severe for birds dependent on attributes such as dead wood, old trees and structurally complex forests. With a focus on the non-tropical parts of the Northern Hemisphere, the text addresses the fundamental evolutionary and ecological aspects of forest birds using original data analyses and synthesising reviews. The characteristics of bird assemblages and their habitats in different European forest types are explored, together with the macroecological patterns of bird diversity and conservation issues. The book provides a valuable reference for ecologists, ornithologists, conservation professionals, forest industry employees, and those interested in birds and nature.

This book integrates the different prospective, scientific and practical experience of researchers as well as beneficiaries and stakeholders in the field of forest conservation in Southeast Europe. The book stresses the importance of improving the adaptability of these ecosystems to the impacts of climate change. Gathered around a common idea, the book presents the latest results in forest genetic resources conservation at national and regional level. The chapters are written by experts from: Bosnia and Herzegovina, Bulgaria, Croatia, FYR Macedonia, Greece, Montenegro, Romania, Serbia and Slovenia. The book presents the current state, legal and institutional framework for conservation and management of forest genetic resources, case studies and best practices in the application of different conservation methods and techniques (in situ and ex situ) as well as climate change aspects in this area. This book will be of particular interest to scientists and experts in the field of forestry, environmental protection and rural development, bachelor, master and doctoral students, as well as for anyone interested in the conservation issues fuelled by ethical and economic motives.
