This book was released on 1995 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report reviews the nature of wind damage in forest stands and relates that damage to the silvicultural systems used or being developed for management of boreal mixedwoods. The report gives detailed consideration to the approaches for minimizing wind damage in released white spruce understory specific to the two-stage harvesting and silvicultural system. The review addresses the individual tree stability, stand stability, and external stability factors such as site characteristics, topography, windiness of the region, and sheltering effects of adjacent stands, and relates these to a framework for recognizing high-risk sites and stands. The report also discusses principles of wind damage management in the context of designing silvicultural systems with incremental wind protection levels.

Download or read book Alternative Silvicultural Systems for Ontario s Boreal Mixedwoods written by Christopher Herbert Richard Wedeles and published by Sault Ste. Marie, Ont. : Great Lakes Forestry Centre. This book was released on 1995 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summarises the potential use of alternative silvicultural (harvesting) systems on the productivity of boreal mixedwood forests. Begins with an overview of the ecology of boreal mixedwoods, including physical environment, stand dynamics, and landscape ecology; then provides detailed reviews of modified clear-cutting systems (including strip cutting, patch cutting, and seed-tree cutting), shelterwood systems, and selection systems (including group selection and individual tree selection). Also briefly discusses the environmental considerations that are associated with these systems (effects on soil, water resources, wildlife, and aesthetics). Concludes with a discussion of areas of uncertainty in the application of alternative systems and the perceived problems that have limited their use in boreal mixedwoods.
Download or read book Wind Damage in a Partially Harvested Boreal Mixedwood Stand in Northeastern Ontario written by James A. Rice and published by . This book was released on 2011 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of the study was to test a series of innovative silvicultural treatment packages designed to create mixtures of hardwoods and conifers while monitoring changes in ecological and silvicultural indicators of sustainability. The effects of wind damage on residual trees were monitored at the Stand Level Adaptive Management (SLAM) study site east of Cochrane, Ontario. The goals of this component of the study were to quantify and compare the effects of wind damage between partially harvested and unharvested portions of stands after harvest and to determine their influence on achieving the silvicultural objectives of the partial harvest treatment. Here the authors report the amount and distribution of wind damage in the residual stands at 1, 2, and 4 years after harvest and discuss the effects of this damage on the potential to achieve the desired silvicultural objectives. Specifically, they were interested in the effects of harvest treatments, tree species, direction of fall, stem rot, and stem form on the number and percent of wind damaged trees.--Document.

This book was released on 2013-03-19 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests and any other trees outside the forest play a relevant role all three great UN conventions on Climate Change, on Biodiversity, and on Combating Desertification. The policy processes to implement the measures in these conventions on sub-national, national, regional and international level are extremely complex. And that complexity comes, among other factors, from a blend of different sectoral and national interests, from a large number of scientifically not yet entirely resolved issues and a wide range of different biophysical, social, cultural and political conditions all over the world. The 3rd International DAAD Workshop on “Forests in Climate Change Research and Policy: The Role of Forest Management and Conservation in a Complex International Setting” held in Dubai and Doha along the conference of the parties (COP18) from 28st November to 2nd December had a strong focus on the role of forests and their management in context of international conventions and recent international and national policy. The volume contains 20 papers that are grouped under the topics The Role of Forests and their Management under Climate Change, International Policy Processes, Technical Issues on Remote Sensing, and Country Cases on Forest Management under Climate Change.

This book was released on 2013-03-09 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of the world's forested land is dominated by mixed-species stands. Understanding the complex structure and dynamics of these mixtures is a necessary step in the process of formulating appropriate silvicultural systems for their management. David M. Smith, Professor Emeritus of Silviculture at Yale University, has devoted much of his career to the study of the structure, development, and silvicultural treatment of these kinds of stands. This volume is presented by Professor Smith's collegues to honor the contributions he has made to the field. It contains both reviews of past work and results of current studies of mixed stands: topics range from analysis of forest dynamics in unmanaged stands to studies of silvicultural systems applied to mixtures, with examples drawn from boreal, temperate, and tropical regions. Much of the work stresses the importance of understanding the characteristic growth patterns of individual species within mixed stands, and how species interactions shape developmental patterns.

This book was released on 2003 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, allometry is defined as the proportional size relationship between two parts or attributes of a plant at a single point in time. The paper describes a project to test the effectiveness of crown characteristics for estimating tree growth potential of the main boreal mixedwood species. The investigation was carried out at four fire-origin boreal mixedwood stands in north-west Ontario and several allometric measurements were derived for sample trees (spruce, fir, aspen) at each site. Based on crown & bole allometry calculations, recommendations are made for managing component species in boreal mixedwood stands.

Available in PDF, EPUB and Kindle. Book excerpt: ECOLOGICAL SILVICULTURAL SYSTEMS Unleash the natural power and adaptability of forests with this cutting-edge guide For generations, silvicultural systems have focused largely on models whose primary objective is the production of timber, leading to drastically simplified forests with reduced ecological richness, diversity, and complexity. Ecological silviculture, by contrast, focuses on producing and maintaining forests with “all their parts”—, that is, with the diversity and flexibility to respond and adapt to global changes. Ecological silviculture seeks to emulate natural development models and sustain healthy forests serving multiple values and goals. Ecological Silvicultural Systems provides a comprehensive introduction to these approaches and their benefits tailored to diverse types of forests, designed for forest management professionals. It provides a series of exemplary models for ecological silviculture and surveys the resulting forest ecosystems. The result is a text that meets the needs of professionals in forestry and natural resource management with an eye towards sustaining healthy forest ecosystems, adapting them to climate change, protecting them from invasive species, and responding to changing market forces. Ecological Silvicultural Systems readers will also find: Detailed treatment of forest ecosystems in North America, Europe, South America, and Australia A broad field of contributors with decades of combined expertise on multiple continents Discussion of pine woodlands; temperate hardwood forests, boreal forests, temperate rainforests, and more Ecological Silvicultural Systems is a useful reference for professional foresters, wildlife habitat managers, restoration ecologists, and undergraduate and graduate students in any of these fields.
