This book links the emerging concepts of complexity, complex adaptive system (CAS) and resilience to forest ecology and management. It explores how these concepts can be applied in various forest biomes of the world with their different ecological, economic and social settings, and history. Individual chapters stress different elements of these concepts based on the specific setting and expertise of the authors. Regions and authors have been selected to cover a diversity of viewpoints and emphases, from silviculture and natural forests to forest restoration, and from boreal to tropical forests. The chapters show that there is no single generally applicable approach to forest management that applies to all settings. The first set of chapters provides a global overview of how complexity, CAS and resilience theory can benefit researchers who study forest ecosystems. A second set of chapters provides guidance for managers in understanding how these concepts can help them to facilitate forest ecosystem change and renewal (adapt or self-organize) in the face of global change while still delivering the goods and services desired by humans. The book takes a broad approach by covering a variety of forest biomes and the full range of management goals from timber production to forest restoration to promote the maintenance of biodiversity, quality of water, or carbon storage.

This textbook offers a detailed overview of the current state of knowledge concerning the ecology and management of compositionally and structurally diverse forests. It provides answers to central questions such as: What are the scientific concepts used to assess the growth, dynamics and functioning of mixed-species forests, how generalizable are they, and what kind of experiments are necessary to develop them further? How do mixed-species stands compare with monocultures in relation to productivity, wood quality, and ecological stability in the face of stress and disturbances? How are the effects of species mixtures on ecosystem functioning influenced by the particular species composition, site conditions, and stand structure? How does any over- or underyielding at the forest-stand level emerge from the tree and organ level, and what are the main mechanisms behind mixing effects? How can our current scientific understanding of mixed-species forests be integrated into silvicultural concepts as well as practical forest management and planning? Do the ecological characteristics of mixed-species stands also translate into economic differences between mixtures and monocultures? In addition, the book addresses experimental designs and analytical approaches to study mixed-species forests and provides extensive empirical information, general concepts, models, and management approaches for mixed-species forests. As such, it offers a valuable resource for students, scientists and educators, as well as professional forest planners, managers, and consultants.

Humans have influenced the landscapes and forests throughout the temperate and boreal zones for millennia. Restoration of Boreal and Temperate Forests, Second Edition focuses on the negative impact of human activity, and explains the importance of forest restoration as a way to repair habitat, restore forest structure and function, and counteract the lasting effects of humanity. The book offers broad geographic coverage, as well as a combination of review and case study chapters providing social and policy contexts for restoration of specific forest types. This revised edition begins with a historical context for restoration, provides a conceptual framework for understanding the relationship between degradation and restoration, and defines terms within that framework. While building on the first edition, it presents the response of restorationists to the current challenges of interpreting scattered science on forest history, stand development, and natural processes. It combines applicable experience designed to improve present and future ecological and social sustainability. Describes restoration in the context of rapid social, economic, environmental, and climate change Looks toward the future, presenting several completely new topics in forest restoration Covers different starting points for restoration, from non-forest to degraded forest Restoration of Boreal and Temperate Forests, Second Edition aids in the understanding of the diverse cultural and ecological contexts for restoration of temperate and boreal forests, and the creation of a better foundation of documented knowledge to support future and existing restoration decisions.

Forests are valued not only for their economic potential, but also for the biodiversity they contain, the ecological services they provide, and the recreational, cultural, and spiritual opportunities they provide. The Ecological Forest Management Handbook provides a comprehensive summary of interrelated topics in the field, including management concepts, forest models, and ecological indicators. Featuring contributions from experts on the three main forest types—boreal, temperate, and tropical—this book presents in-depth coverage of important issues in ecological forest management and includes case studies addressing ecological and socioeconomic issues. It illustrates how ecological forest management is a complex process that requires broad ecological knowledge while giving readers a deeper understanding of basic principles and applications.

Ein neuer Blick auf alte Freunde Erstaunliche Dinge geschehen im Wald: Bäume, die miteinander kommunizieren. Bäume, die ihren Nachwuchs, aber auch alte und kranke Nachbarn liebevoll umsorgen und pflegen. Bäume, die Empfindungen haben, Gefühle, ein Gedächtnis. Unglaublich? Aber wahr! – Der Förster Peter Wohlleben erzählt faszinierende Geschichten über die ungeahnten und höchst erstaunlichen Fähigkeiten der Bäume. Dazu zieht er die neuesten wissenschaftlichen Erkenntnisse ebenso heran wie seine eigenen unmittelbaren Erfahrungen mit dem Wald und schafft so eine aufregend neue Begegnung für die Leser: Wir schließen Bekanntschaft mit einem Lebewesen, das uns vertraut schien, uns aber hier erstmals in seiner ganzen Lebendigkeit vor Augen tritt. Und wir betreten eine völlig neue Welt ...

Was wissen wir heute über die natürliche Produktivität der Auwälder an großen Flüssen vor der Regulierung und über deren ehemalige Funktion als Rohstoffquelle für erneuerbare Energie? Können wir aus einer historischen Rekonstruktion der ehemals verfügbaren Holzressourcen Rückschlüsse für ein nachhaltiges Ressourcenmanagement ziehen? Die Beantwortung dieser Fragen war Ziel des Forschungsprojekts „Genug Holz für Stadt und Fluss? - Wiens Holzressourcen in dynamischen Donau-Auen“. Am Beispiel der Wiener Donau-Flusslandschaft vor der Regulierung 1820 - 1830 untersuchte ein interdisziplinäres Team bestehend aus Flussmorphologen, Gewässer-, Vegetations- und Forstökologen sowie Umwelthistorikerinnen drei zentrale Themenkreise: (1) Flussmorphologisch-forstökologische Standortsbedingungen und natürliches Potenzial der dynamischen Donau-Auen vor der Regulierung Holzressourcen zu produzieren, (2) Historischer Umgang einer ehemals biomassebasierten Gesellschaft mit lokal verfügbaren Holzressourcen in Wien, (3) Zukünftige Entwicklungsmöglichkeiten von Donau-Auwäldern unter Berücksichtigung ökologisch-naturschutzfachlicher Ziele und forstwirtschaftlicher Anforderungen für die Produktion erneuerbarer Energieressourcen. Neben naturwissenschaftlichen Erkenntnissen für eine nachhaltige Nutzung naturnaher, teilweise „redynamisierter“ Auwälder lieferte das Forschungsprojekt auch neue Beiträge zur Wiener Stadtgeschichte und zur historischen Veränderung der Donau-Flusslandschaft.
