Book Description
Excerpt from Natural Regeneration of Swamp Black Spruce in Minnesota Under Various Cutting Systems However, when the evidence is correlated with previous work at the Station and elsewhere, plus silvical information on the species, a pattern emerges. Any silvicultural system must provide for satisfactory regenera tion or ultimately it will fail. Of course, growth and yield of the stands, and costs and returns for the total operation are also crucial factors in choosing a cutting system. But economic decisions are only as sound as the biological information upon which they rest. This report is intended primarily as a contribution to silvicultural knowl edge of the regeneration phase of swamp spruce management.

Book Description
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.

Book Description
A valuable working resource for professionals. An excellent text for advanced forestry students . . . This unique book provides students and professionals with a broad-based knowledge of contemporary silviculture theory and practice.Throughout, the authors emphasize fundamental questions of edaphic,physiographic, and climatic site factors, as well as ecologicalrelationships and silvical characteristics of major tree species.Updated and expanded to reflect the many scientific, socioeconomic,and public policy trends that have had a profound impact onsilviculture over the past decade, this Third Edition of RegionalSilviculture of the United States: * Brings together the knowledge and expertise of fourteen leadingexperts from around the nation * Provides a rational framework with which to critically assessforest data and to develop innovative silvicultural solutions * Features region-by-region coverage of the eleven major foresttypes in the continental U.S. and Alaska * Offers a detailed look at practices that promote a wide range offorest resources--from wood production and outdoor recreation, towildlife habitat and range forage production * Now includes more in-depth coverage of such crucial themes asbiodiversity, endangered species, habitat fragmentation, foresthealth, landscape management, neotropical migrants, and more "...silviculture is not reducible to a series of rules; it must beflexible and adaptable to a variety of conditions. Much of it is anart as well as a synthesis of ecology and economics. There is nosingle best answer to how a stand should be managed. Andinstitutional and societal constraints must be considered." --fromthe Preface by John W. Barrett Regional Silviculture of the United States, Third Edition is not a"cookbook,"offering pat recipes for solving "typical" silviculturalproblems. Instead, it arms those responsible for the developmentand care of forests with something far more valuable--a rationalframework for the analysis of forest data and the development ofinnovative solutions tailored to specific forest types and theshifting politicoeconomic constraints under which silviculturalistsmust work. One way in which this book achieves that goal is by providingreaders with a broad-based knowledge of contemporary silviculturetheory and practice. In chapters organized according to the elevenmajor forest regions of the continental U.S., fourteen recognizedexperts from around the nation--each of them a specialist in aparticular region of operation--offer their valuable insights andobservations on silviculture in general and on varioussilvicultural practices with which they are familiar. Throughout,the authors are attentive to fundamental considerations of edaphic,physiographic, and climatic site factors, as well as ecologicalrelationships and silvical characteristics of major treespecies. This Third Edition of John W. Barrett's classic has been revisedand expanded to encompass a number of important themes which haverisen to prominence within silviculture over the past decade,including biodiversity, endangered species, habitat fragmentation,forest health, landscape management, and neotropicalmigrants. Timely, authoritative, and comprehensive in scope, RegionalSilviculture of the United States, Third Edition is a valuableresource for foresters, forestry students, ecologists,environmental scientists, and all those concerned with development,management, and preservation of our most valuable nationaltreasure.
