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.

Climate changes, particularly warming trends, have been recorded around the globe. For many countries, these changes in climate have become evident through insect epidemics (e.g., Mountain Pine Beetle epidemic in Western Canada, bark beetle in secondary spruce forests in Central Europe), water shortages and intense forest fires in the Mediterranean countries (e.g., 2005 droughts in Spain), and unusual storm activities (e.g., the 2004 South-East Asia Tsunami). Climate changes are expected to impact vegetation as manifested by changes in vegetation extent, migration of species, tree species composition, growth rates, and mortality. The International Panel on Climate Change (IPCC) has included discussions on how forests may be impacted, and how they may be used to mitigate the impacts of changes in climate, to possibly slow the rate of change. This book provides current scientific information on the biological and economical impacts of climate changes in forest environments, as well as information on how forest management activities might mitigate these impacts, particularly through carbon sequestration. Case studies from a wide geographic range are presented. This information is beneficial to managers and researchers interested in climate change and impacts upon forest environments and economic activities. This volume, which forms part of Springer’s book series Managing Forest Ecosystems, presents state-of-the-art research results, visions and theories, as well as specific methods for sustainable forest management in changing climatic conditions.
Forest Biometrics presents the methods of mathematical statistics and biometrics that are significant to forestry. This book explores other fields related to forestry, which are explained with the help of a large number of practical examples. Organized into 25 chapters, this book starts with an overview of the variety of data that play a significant role in forest management, including the age of trees, the damage caused by storms, the fluctuation of timber prices, bark beetle infestation, and timber volume. This text then examines the factors that are responsible for a random distribution of the values in biological experimentation. Other chapters consider the important advantages of sample surveys compared to complete enumerations, include cheaper samples, wider applicability, quick results, and greater accuracy. The final chapter deals with the factors to be considered in determining the best time for harvesting of timber. This book is a valuable resource for students, research project leaders, and practical workers.
Insects, being poikilothermic, are among the organisms that are most likely to respond to changes in climate, particularly increased temperatures. Range expansions into new areas, further north and to higher elevations, are already well documented, as are physiological and phenological responses. It is anticipated that the damage by insects will increase as a consequence of climate change, i.e. increasing temperatures primarily. However, the evidence in support of this common “belief” is sparse. Climate Change and Insect Pests sums up present knowledge regarding both agricultural and forest insect pests and climate change in order to identify future research directions.
Up to the end of the 19th century, many European forests suffered from devastation and soil deterioration, which caused fears of timber shortage. In order to counteract this possible shortage, many forest areas were reforested with coniferous tree species, especially Norway spruce (Picea abies [L.] Karst). Consequently, coniferous forests (often Norway spruce forests), consisting of trees of the same age, were established on many sites naturally dominated by broadleaves. As a result, damages caused by storm, snow, ice, drought, insects, fungi and possibly soil degradation seemed to occur more frequently in these secondary Norway spruce forests than in forests consisting of species better adapted to the ambient conditions. Conversion of Norway spruce stands may reduce these risks and upgrade biodiversity and the genetic potential of forests. As the economic results of forestry, future wood markets and various other goods and services that are provided to society by forest ecosystems, are affected by present and future decision-making, all aspects of conversion must be well understood. EFI's Regional Project Centre, CONFOREST, is continuously striving to improve implementation of conversion projects by consolidation of the expertise available in all forestry disciplines. This book comprises the findings in all conversion-related areas aiming to consider ecosystem needs while ensuring availability of silvicultural methods and operational feasibility of their implementation. Simultaneously, the cost-effectiveness of conversion scenarios is analysed by forestry economists. Since a change in public perception and ecological awareness may cause policy makers to either or not endorse further conversion efforts, input by experts in forestry politics is also provided.
Based on the research of an interdisciplinary team of sociologists, geographers and economists, this book focuses on understanding farming transitions in Europe. The book discusses the importance of understanding transition pathways towards sustainability using case studies from Bulgaria, the Czech Republic, France, Germany, Greece, Portugal and the United Kingdom. Assessing the utility of the multi-level perspective in transition theory for addressing contemporary issues, the book identifies future research needs and possible approaches, making this an essential read for researchers interested in issues of rural and agricultural change.
The large-scale application of new silvicultural systems has become a political reality in many parts of the world. This involves a gradual transformation of traditional silvicultural practice towards Continuous Cover Forestry, also known as near-natural forest management, favouring mixed uneven-aged stands, site-adapted tree species and selective harvesting. Selective harvesting systems have a long tradition. Specific CCF-related resource assessment, forecasting and sustainable harvest control techniques have been developed, but details about their use are not widely known. The objective of this volume is to present state-of-the-art research results and techniques relating to CCF management with an emphasis on systems engineering and modelling. Using a very simple classification based on the development of timber volume over age or time we may distinguish two types of sustainable forest management systems. Rotation forest management (RFM) systems, characterized by standard silvicultural treatments and repetitive cycles of clearfelling followed by planting; and continuous cover forestry (CCF) systems which are characterized by selective harvesting and natural regeneration, resulting in uneven-aged structures and frequently also in multi-species forests. The distinction is usually the result of decisions relating to the cost of timber harvesting, simplicity of management, or various intangible benefits. The oldest and most perfect examples of CCF systems are the so called plenter selection forests found in France, Switzerland, Slowenia and Germany. Today, CCF systems are encountered in various regions of Europe, North America and in some tropical and sub-tropical forests of South Africa, Asia and South America.
An integrated treatment of forest nutrition management that draws on the fields of silviculture, soil studies, ecology, and economics to provide broad-based information on how to enhance the nutritional status of forest soils in order to increase their long-term stand productivity. Covers the use of fertilizers to enhance biological nitrogen fixation and how the nutrition status of forests is affected by other operations, such as harvesting and site preparation. Includes methods for assessing nutrient status, the economics of nutrition management, and models to aid in decision making. Written for the non-specialist needing a clear conceptual base for applying forest nutrition science to management. Numerous examples of successful forest management illustrate concepts.
