OPUS: The function of dead wood in forest ecosystems: A synthesis for the next decade

点击翻译按钮获取中文摘要

Dead trees are part of every forested landscape and ecosystem, yet much remains to be learned about their role in these systems. Although the study of dead trees is in its infancy, a significant body of literature and associated data have become available in the last 25 years that can be used to describe the many functions of dead wood in forested ecosystems of the world. Over a two-year period this project will synthesize results from journal articles, past reviews, and data analyses related to the role of dead trees in forests leading to an updated synthesis in book form. Specific activities include: an updated literature review and analysis of the function of dead trees in forests of the world; reanalysis of long-term experimental data on wood decomposition; compilation of articles, images, and photographs related to dead trees; updating and expansion of previously published reviews and book chapters; and synthesis of all these materials into a book. Dead trees are one of the most common objects in forests, yet their function is often ascribed as "waste". In reality dead trees serve many important ecological functions such as a habitat and a food source for a wide host of organisms, part of the physical structure in forest streams, a source of energy, water, carbon, and nutrients for forest organisms, as well as fuel for either human use or for wildfires. It is of critical importance in a world in which the number and volume of dead trees is likely to be increasing, that their role and dynamics be better understood not only by specialists but also by all those managing and/or using forests. This scientific synthesis therefore represents a major improvement in understanding a major component of all forests. To enhance public understanding and appreciation of this important natural resource a parallel project will create visual and written presentations of dead trees that will be distributed in multiple formats such as public displays and a popular book.
