      Mixed-species forests

      • 663 pages
      • 24 hours of reading

      This textbook provides a comprehensive overview of the ecology and management of diverse forests, focusing on key questions related to mixed-species stands. It explores scientific concepts for assessing growth, dynamics, and functioning of these forests, examining their generalizability and necessary experimental developments. The text compares mixed-species stands with monocultures regarding productivity, wood quality, and ecological stability under stress and disturbances. It investigates how species mixtures affect ecosystem functioning, influenced by species composition, site conditions, and stand structure. Additionally, it delves into the mechanisms behind over- or underyielding at the forest-stand level, linking tree and organ-level interactions. The book emphasizes integrating current scientific understanding of mixed-species forests into silvicultural practices and forest management planning. It also considers whether the ecological traits of mixed-species stands lead to economic differences compared to monocultures. Furthermore, the text discusses experimental designs and analytical methods for studying mixed-species forests, offering extensive empirical data, general concepts, models, and management strategies. This resource is valuable for students, scientists, educators, and professionals in forest planning and management.

      Forest dynamics, growth and yield

      From Measurement to Model

      The aim of this book is to improve the understanding of forest dynamics and the sustainable management of forest ecosystems. How do tree crowns, trees or entire forest stands respond to thinning in the long term? What effect do tree species mixtures and multi-layering have on the productivity and stability of trees, stands or forest enterprises? How do tree and stand growth respond to stress factors such as climate change or air pollution? Furthermore, in the event that one has acquired knowledge about the effects of thinning, mixture and stress, how can one make that knowledge applicable to decision-making in forestry practice? The experimental designs, analytical methods, general relationships and models for answering questions of this kind are the focus of this book. Given the structures dealt with, which range from plant organs to the tree, stand and enterprise levels, and the processes analysed in a time frame of days or months to decades or even centuries, this book is directed at all readers interested in trees, forest stands and forest ecosystems. This work has been compiled for students, scientists, lecturers, forest planners, forest managers, and consultants.
