This book was released on 2011-06-29 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of trees live and grow all around us, and we all recognize the vital role they play in the world’s ecosystems. Publicity campaigns exhort us to plant yet more. Yet until recently comparatively little was known about the root causes of the physical changes that attend their growth. Since trees typically increase in size by three to four orders of magnitude in their journey to maturity, this gap in our knowledge has been a crucial issue to address. Here at last is a synthesis of the current state of our knowledge about both the causes and consequences of ontogenetic changes in key features of tree structure and function. During their ontogeny, trees undergo numerous changes in their physiological function, the structure and mechanical properties of their wood, and overall architecture and allometry. This book examines the central interplay between these changes and tree size and age. It also explores the impact these changes can have, at the level of the individual tree, on the emerging characteristics of forest ecosystems at various stages of their development. The analysis offers an explanation for the importance of discriminating between the varied physical properties arising from the nexus of size and age, as well as highlighting the implications these ontogenetic changes have for commercial forestry and climate change. This important and timely summation of our knowledge base in this area, written by highly respected researchers, will be of huge interest, not only to researchers, but also to forest managers and silviculturists.
Download or read book Soil and Root Damage in Forestry written by Iwan Wasterlund and published by Elsevier. This book was released on 2020-08-26 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry has significantly impacted our forests, but an often-overlooked issue is the effect of harvesting on soils and root systems. Soil and Root Damage in Forestry explains how soil and roots might be damaged through logging activities or silvicultural activities, how resulting root diseases impact the root and soil systems, and the impacts of chemical applications on the soil and root system. This book goes beyond the ‘why’ to also provide methods to reduce the impacts of machines on soils and offers solutions to minimize the impacts of machines on soils. Soil and Root Damage in Forestry serves as a valuable resource not only for those already working in soil science and forest ecology, but also provides insights for advanced students seeking an entrance to the "hidden half" of the planet. Combines damages to soil and roots in one volume for the first time Includes calculations related to soil strength providing soil scientists and ecologists with methods to estimate root damage Provides suggestions on how to reduce the impact of harvesting on soil and root systems
Download or read book Forest Management and the Water Cycle written by Michael Bredemeier and published by Springer Science & Business Media. This book was released on 2010-10-25 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: The protective function of forests for water quality and water-related hazards, as well as adequate water supplies for forest ecosystems in Europe, are potentially at risk due to changing climate and changing land-management practices. Water budgets of forest ecosystems are heavily dependent on climate and forest structure. The latter is determined by the management measures applied in the forestry sector. Various developments of forest management strategies, imposed on a background of changing climate, are considered in assessing the overall future of forest–water interactions in Europe. Synthesizing recent research on the interactions of forest management and the water regime of forests in Europe and beyond, the book makes an important contribution to the ongoing dialogue between scientists dealing with different scales of forest-water interactions. This collaborative endeavour, which covers geographic and climatic gradients from Iceland to Israel and from southern Spain to Estonia and Finland, was made possible through the COST Action "Forest Management and the Water Cycle (FORMAN)", which was launched in 2007 (http://www.forestandwater.eu/). The book will be of particular interest to the research community involved in forest ecosystem research and forest hydrology, as well as landscape ecologists and hydrologists in general. It will also provide reference material for forest practitioners and planners in hydrology and land use.

Available in PDF, EPUB and Kindle. Book excerpt: Salvage logging—removing trees from a forested area in the wake of a catastrophic event such as a wildfire or hurricane—is highly controversial. Policymakers and those with an economic interest in harvesting trees typically argue that damaged areas should be logged so as to avoid “wasting” resources, while many forest ecologists contend that removing trees following a disturbance is harmful to a variety of forest species and can interfere with the natural process of ecosystem recovery. Salvage Logging and Its Ecological Consequences brings together three leading experts on forest ecology to explore a wide range of issues surrounding the practice of salvage logging. They gather and synthesize the latest research and information about its economic and ecological costs and benefits, and consider the impacts of salvage logging on ecosystem processes and biodiversity. The book examines • what salvage logging is and why it is controversial • natural and human disturbance regimes in forested ecosystems • differences between salvage harvesting and traditional timber harvesting • scientifically documented ecological impacts of salvage operations • the importance of land management objectives in determining appropriate post-disturbance interventions Brief case studies from around the world highlight a variety of projects, including operations that have followed wildfires, storms, volcanic eruptions, and insect infestations. In the final chapter, the authors discuss policy management implications and offer prescriptions for mitigating the impacts of future salvage harvesting efforts. Salvage Logging and Its Ecological Consequences is a “must-read” volume for policymakers, students, academics, practitioners, and professionals involved in all aspects of forest management, natural resource planning, and forest conservation.

Download or read book Impacts on Soils and Residual Trees from Cut to length Thinning Operations in California s Redwood Forests written by Kyungrok Hwang and published by . This book was released on 2018 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: In northern California, a cut-to-length (CTL) system was used for the first time to harvest young redwood forests (Sequoia sempervirens (Lamb. ex D. Don) Endl.). However, landowners and public agencies are concerned about the potential negative impacts of CTL logging to soils and residual trees since the extent and amount of CTL impacts are unknown in these forests. This study was designed to (1) determine soil physical property using bulk density (BD) and hydraulic conductivity (HC) (2) examine the characteristics of stand damage after CTL harvesting, and (3) compare the scar size differences between tree growing patterns (individuals vs. clumps). Soil samples were collected from transects at two locations (track and center) on forwarder trails and reference points at three levels of soil depths (0-5, 10-15, and 20-25 cm), and HC data on the soil surface were measured adjacent to the BD sample point. Stand damage was assessed regardless of scar size. I found 25 to 30% increase in BD at 0-5 cm of soil depth on the track compared to reference, but HC showed the inconsistent results due to high variability, so a greater size of HC samples would be needed. Approximately, 16.2-32.2% of residual trees were damaged during operations, and I detected that most damage was located near the forwarding trails and ground level. In addition, I found the larger-sized-scars on clumped trees compared to individual trees in scar width and length. CTL thinning operations may be viable, however, future studies should be performed after few years to evaluate the feasibility of this harvesting system on longer-term tree growth.
