This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An understanding of trajectories in long-term forest development is essential for examining several fundamental issues in forest ecology and management. Long-term forest development has important implications for issues as diverse as forest productivity, carbon storage, biological diversity, and ecological forestry methods. While much has been learned from studies of old-growth forests, a limitation is that these have necessarily been brief snapshots of species composition and forest structure at one point in time from which accurate trends are difficult to infer. The overarching themes of this dissertation are the long-term trajectory of forest development and the impact of the historic natural disturbance regime on that trajectory. Specific objectives were: (1) to quantify long-term trends in above-ground tree biomass and stand structure in northern hardwood forests, and effects of the natural disturbance regime, (2) to estimate the frequency of structural stand stages, along with residence times and transition rates among stages, under several disturbance regimes, and (3) to develop a quantitative approach to evaluating demographic sustainability of tree populations under several conditions, including those of restricted recruitment. Computer simulation with the CANOPY model was used to clarify long-term trends. However, to the extent possible, these model predictions were verified against available field data, including an extensive field survey and a 30-year record of change on permanent plots in the Porcupine Mountains Wilderness State Park. Major conclusions from this work were: (1) The Bormann-Likens hypothesis of a peak in biomass followed by a decline to a lower level was largely supported by both simulation and field data. The asymptotic biomass trend documented in recent chronosequences may be a consequence of using maximum tree age to estimate stand age. (2) The majority of landscapes of old-growth northern hardwoods is occupied by non-equilibrium stands, but nearly 1/3 was also structurally indistinguishable from steady state. Individual stands were highly dynamic, spending only a few decades in any structural stage. (3) Minimum sustainable tree populations had a variable slope in their size distribution. Enforcing a shallow fixed slope in understory trees typical of those used in uneven-aged management for larger trees rendered the stand unsustainable.

Available in PDF, EPUB and Kindle. Book excerpt: Classical silviculture has often emphasized timber models, fundamentally based in production agriculture. This books presents silvicultural methods based in natural forest models—models that emulate natural disturbances and development processes, sustain biological legacies, and allow time to take its course in shaping stands. These methods, dubbed “ecological forestry,” have been successfully implemented by foresters for decades managing a wide variety of forestlands. Ecological silvicultural strategies protect threatened and rare species, sustain biological diversity, and provide habitat for game and non-game species, all while providing timber in profitable ways.

Available in PDF, EPUB and Kindle. Book excerpt: S2Two even-age management systems, progressive strip cutting and block clearcutting, have been studied since 1970 on small watersheds at the Hubbard Brook Experimental Forest, New Hampshire. In the strip cutting, all merchantable trees were harvested in a series of three strips over 4 years (1970-74). In the block clearcutting, all trees were harvested in a single operation in 1970. This paper contrasts progressive strip cutting and block clearcutting for the 10-year period after initiation of harvest in terms of hydrologic response, erosion losses, stream water ions, nutrient leaching, nutrient removals in harvested products, and natural regeneration of vegetation.S3.

Download or read book Natural Disturbances and Historic Range of Variation written by Cathryn H. Greenberg and published by Springer. This book was released on 2015-10-26 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the historic range of variation (HRV) in the types, frequencies, severities and scales of natural disturbances, and explores how they create heterogeneous structure within upland hardwood forests of the Central Hardwood Region (CHR). The book was written in response to a 2012 forest planning rule which requires that national forests to be managed to sustain ‘ecological integrity’ and within the ‘natural range of variation’ of natural disturbances and vegetation structure. Synthesizing information on HRV of natural disturbance types, and their impacts on forest structure, has been identified as a top need.

This book was released on 2011-08-03 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume addresses a rising concern among natural resource scientists and management professionals about decline of the many plant and animal species associated with early-successional habitats, especially within the Central Hardwood Region of the USA. These open habitats, with herbaceous, shrub, or young forest cover, are disappearing as abandoned farmland, pastures, and cleared forest patches return to forest. There are many questions about “why, what, where, and how” to manage for early successional habitats. In this book, expert scientists and experienced land managers synthesize knowledge and original scientific work to address questions on such topics as wildlife, water, carbon sequestration, natural versus managed disturbance, future scenarios, and sustainable creation and management of early successional habitat in a landscape context.

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.
Download or read book Forest Ecology written by Daniel M. Kashian and published by John Wiley & Sons. This book was released on 2023-02-13 with total page 789 pages. Available in PDF, EPUB and Kindle. Book excerpt: FOREST ECOLOGY Authoritative resource covering traditional plant ecology topics and contemporary components such as climate change, invasive species, ecosystem services, and more Forest Ecology provides comprehensive coverage of the field, focusing on traditional plant ecology topics of tree structure and growth, regeneration, effects of light and temperature on tree physiology, forest communities, succession, and diversity. The work also reviews abiotic factors of light, temperature, physiography (landforms and topography), soil, and disturbance (especially fire), and provides coverage of ecosystem-level topics including carbon storage and balance, nutrient cycling, and forest ecosystem productivity. The 5th edition of Forest Ecology retains the readability and accessibility of the previous editions and includes important additional topical material that has surfaced in the field. All topics are approached with a landscape ecosystem or geo-ecological view, which places biota (organisms and communities) in context as integral parts of whole ecosystems that also include air (atmosphere and climate), topography, soil, and water. As such, the book fills a niche utilized by no other forest ecology text on the market, helping students and researchers consider whole ecosystems at multiple scales. Sample topics covered in Forest Ecology include: Contemporary components of forest ecology, including climate change, invasive species, diversity, ecological forestry, landscape ecology, and ecosystem services. Characteristics of physiography important for forest ecosystems, including its effects on microclimate, disturbance, soil, and vegetation. Genetic diversity of woody plants and genecological differentiation of tree species, including the importance of hybridization, polyploidy, and epigenetics. Site quality estimation using tree height and ground flora, and multiple-factor approaches to forest site and ecosystem classification and mapping. Forest Ecology is a highly accessible text for students, but it also serves as an excellent reference for academics. In addition, practitioners of forest ecology can also harness the information within to gain better insight into the field for practical application of concepts.
Download or read book Ecology and Recovery of Eastern Old Growth Forests written by Andrew M. Barton and published by Island Press. This book was released on 2018-11-08 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: The landscapes of North America, including eastern forests, have been shaped by humans for millennia, through fire, agriculture, hunting, and other means. But the arrival of Europeans on America’s eastern shores several centuries ago ushered in the rapid conversion of forests and woodlands to other land uses. By the twentieth century, it appeared that old-growth forests in the eastern United States were gone, replaced by cities, farms, transportation networks, and second-growth forests. Since that time, however, numerous remnants of eastern old growth have been discovered, meticulously mapped, and studied. Many of these ancient stands retain surprisingly robust complexity and vigor, and forest ecologists are eager to develop strategies for their restoration and for nurturing additional stands of old growth that will foster biological diversity, reduce impacts of climate change, and serve as benchmarks for how natural systems operate. Forest ecologists William Keeton and Andrew Barton bring together a volume that breaks new ground in our understanding of ecological systems and their importance for forest resilience in an age of rapid environmental change. This edited volume covers a broad geographic canvas, from eastern Canada and the Upper Great Lakes states to the deep South. It looks at a wide diversity of ecosystems, including spruce-fir, northern deciduous, southern Appalachian deciduous, southern swamp hardwoods, and longleaf pine. Chapters authored by leading old-growth experts examine topics of contemporary forest ecology including forest structure and dynamics, below-ground soil processes, biological diversity, differences between historical and modern forests, carbon and climate change mitigation, management of old growth, and more. This thoughtful treatise broadly communicates important new discoveries to scientists, land managers, and students and breathes fresh life into the hope for sensible, effective management of old-growth stands in eastern forests.
Download or read book The Ecology and Silviculture of Mixed Species Forests written by M.J. Kelty and published by Springer Science & Business Media. 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.
