Book Description
The objective of this bulletin is to summarize British experience of alternative silvicultural systems to clear-cutting. The study highlights the lessons which have been learnt in managing irregular forestry, and in converting high forest managed by clear-cutting to other systems.

Book Description
This book describes the theoretical basis and practical application of 20 diverse silvicultural systems for the benefit of ecologists, land-use managers and other professionals. These systems offer the key to regenerating, tending, and harvesting forests in an era of rapid deforestation and increasing demand for wood as fuel and building material. The approaches described here are being used successfully in widely different parts of the world, from Europe to the tropical rain forests, where reduced forest areas must be carefully managed in order to produce the highest possible sustained yield of timber products compatible with environmental protection and preservation. The systematic presentation and discussion of advantages and disadvantages of each program enables readers to select and apply the program most suitable for their needs.

Book Description
CONTINUOUS COVER FORESTRY Gain expertise in the development of healthier, more sustainable forests with this indispensable guide Continuous Cover Forestry (CCF) is an approach to forest management with over a century of history, one which applies ecological principles to the project of developing biologically diverse, structurally complex forests. Long used as the standard forest management method in Central Europe, CCF is generating renewed interest globally for its potential to develop and sustain forests that can withstand climate change impacts, maintain forest biodiversity in the face of major ecological challenges and offer better recreation experience. There is an increasingly urgent need for forest scientists and policymakers to be familiar with the toolkit provided by CCF. Continuous Cover Forestry: Theories, Concepts, and Implementation provides a thorough, up-to-date introduction to the theory and practice of CCF. Beginning with an overview of the method’s history and its foundational principles, the book provides detailed guidance for applying CCF methods to a range of ecological scenarios and forest types. The result is a clear, comprehensive portrait of this increasingly effective set of forestry tools. Continuous Cover Forestry readers will also find: Case studies throughout showing CCF at work in real-world forests Detailed discussion of topics such as forest structure, transformation, silvicultural systems, training, carbon forestry, conservation and more R code ready to take and apply Simple, adaptable models for deriving quantitative guidelines for CCF woodlands Continuous Cover Forestry is ideal for students, scholars and practitioners of forest science, forest ecology, conservation, and environmental management, as well as policymakers dealing with forestry or climate policy.

Book Description
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.

Book Description
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.

Book Description
The long-awaited exploration of permaculture specifically for cooler Northern Hemisphere climates is finally here! Already regarded as the definitive book on the subject, The Earth Care Manual is accessible to the curious novice as much as it is essential for the knowledgeable practitioner. Permaculture started out in the 1970s as a sustainable alternative to modern agriculture, taking its inspiration from natural ecosystems. It has always placed an emphasis on gardening, but since then it has expanded to include many other aspects, from community design to energy use. It can be seen as an overall framework that puts a diversity of green ideas into perspective. Its aims are low work, high output, and genuine sustainability.
