Ecological Silvicultural Systems by Brian J. Palik,Anthony W. D'Amato Pdf
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.
Forest Growth and Timber Quality: Crown Models and Simulation Methods for Sustainable Forest Management by Dennis P. Dykstra Pdf
Explores the relationships between forest management activities and timber quality. Sessions were organized to explore models and simulation methodologies that contribute to an understanding of tree development over time and the ways that management and harvesting activities can influence the quality of timber products recovered from those trees. Five keynote addresses, 29 plenary presentations, and 16 poster presentations covered the full breadth of forest growth and timber quality issues related to forest management. These proceedings comprise 19 papers based on presentations and posters, plus 28 abstracts for presentations. Also includes abstracts and slides from the presentations prepared by three keynote speakers. Illustrations.
INSTANT NATIONAL BESTSELLER NEW YORK TIMES BESTSELLER *WINNER of the 2021 Banff Mountain Book Prize in Mountain Environment and Natural History* *WINNER of the National Outdoor Book Award for Natural History Literature* *SHORTLISTED for the 2022 BC and Yukon Hubert Evans Non-Fiction Book Prize* *SHORTLISTED for the 2022 BC and Yukon Bill Duthie Booksellers’ Choice Award* *SHORTLISTED for the 2021 Science Writers and Communicators of Canada Book Award* A world-leading expert shares her amazing story of discovering the communication that exists between trees, and shares her own story of family and grief. Suzanne Simard is a pioneer on the frontier of plant communication and intelligence; she’s been compared to Rachel Carson, hailed as a scientist who conveys complex, technical ideas in a way that is dazzling and profound. Her work has influenced filmmakers (the Tree of Souls in James Cameron’s Avatar), and her TED talks have been viewed by more than 10 million people worldwide. Now, in her first book, Simard brings us into her world, the intimate world of the trees, in which she brilliantly illuminates the fascinating and vital truths—that trees are not simply the source of timber or pulp but are a complicated, interdependent circle of life; that forests are social, cooperative creatures connected through underground networks by which trees communicate their vitality and vulnerabilities with communal lives not that different from our own. Simard describes up close—in revealing and accessible ways—how trees, living side by side for hundreds of years, have evolved; how they perceive one another, learn and adapt their behaviors, recognize neighbors, and remember the past; how they have agency about their future; how they elicit warnings and mount defenses, compete and cooperate with one another with sophistication: characteristics previously ascribed to human intelligence, traits that are the essence of civil societies. And, at the center of it all, the Mother Trees: the mysterious, powerful forces that connect and sustain the others that surround them.Simard, born and raised in the rain forests of British Columbia, spent her days as a child cataloging the trees from the forest; she came to love and respect them and embarked on a journey of discovery and struggle. Her powerful story is one of love and loss, of observation and change, of risk and reward. And it is a testament to how deeply human scientific inquiry exists beyond data and technology: it’s about understanding who we are and our place in the world. In her book, as in her groundbreaking research, Simard proves the true connectedness of the Mother Tree to the forest, nurturing it in the profound ways that families and humansocieties nurture one another, and how these inseparable bonds enable all our survival.
Drivers of Landscape Change in the Northwest Boreal Region by Valerie Barber Pdf
The northwest boreal region (NWB) of North America is a land of extremes. Extending more than 1.3 million square kilometers (330 million acres), it encompasses the entire spectrum between inundated wetlands below sea level to the tallest peak in North America. Permafrost gradients span from nearly continuous to absent. Boreal ecosystems are inherently dynamic and continually change over decades to millennia. The braided rivers that shape the valleys and wetlands continually change course, creating and removing vast wetlands and peatlands. Glacial melt, erosion, fires, permafrost dynamics, and wind-blown loess are among the shaping forces of the landscape. As a result, species interactions and ecosystem processes are shifting across time. The NWB is a data-poor region, and the intention of the NWB Landscape Conservation Cooperative is to determine what data are not available and what data are available. For instance, historical baseline data describing the economic and social relationships in association with the ecological condition of the NWB landscape are often lacking. Likewise, the size and remoteness of this region make it challenging to measure basic biological information, such as species population sizes or trends. The paucity of weather and climate monitoring stations also compound the ability to model future climate trends and impacts, which is part of the nature of working in the north. The purpose of this volume is to create a resource for regional land and resource managers and researchers by synthesizing the latest research on the historical and current status of landscape-scale drivers (including anthropogenic activities) and ecosystem processes, future projected changes of each, and the effects of changes on important resources. Generally, each chapter is coauthored by researchers and land and natural resource managers from the United States and Canada.

Forecasting Forest Futures by Hamish Kimmins,Kim Scoullar,Brad Seely,Juan A. Blanco,Clive Welham Pdf
Modelling is an important tool for understanding the complexity of forest ecosystems and the variety of interactions of ecosystem components, processes and values. This book describes the hybrid approach to modelling forest ecosystems and their possible response to natural and management-induced disturbance. The book describes the FORECAST family of ecosystem management models at three different spatial scales (tree, stand and landscape), and compares them with alternative models at these three spatial scales. The book will help forest managers to understand what to expect from ecosystem-based forest models; serve as a tool for use in teaching about sustainability, scenario analysis and value trade-offs in natural resources management; and assist policy makers, managers and researches working in assessment of sustainable forest management and ecosystem management. Several real-life examples of using the FORECAST family of models in forest management and other applications are presented from countries including Canada, China, Spain and the USA, to illustrate the concepts described in the text. The book also demonstrates how these models can be extended for scenario and value trade-off analysis through visualization and educational or management games.
Developing Sustainable Mixedwood Practices in a Stand-level Adaptive Management (SLAM) Framework by G. Blake MacDonald,Ontario Forest Research Institute Pdf
This report describes a project to advance knowledge of boreal mixedwood management by testing techniques for achieving productive mixtures of conifers & hardwoods at operational scales. The project is applying treatments in aspen-dominated boreal mixedwood stands at two sites in north-east Ontario. Contrasting approaches are being compared (blended mixtures versus mosaics, partial cutting versus herbicide application, shade-tolerant versus shade-intolerant conifer regeneration) to help identify best practices. Treatment effectiveness is to be assessed by measuring regeneration growth, vegetation succession, soil nutrient dynamics, and changes in invertebrate populations. The report includes information on the site characteristics, treatments, pre- & post-harvest measurement methods, data analysis, knowledge transfer from the project, and project challenges & prospects.
