Book excerpt: Evidence is mounting that redwood forests, like many other ecosystems, cannot survive as small, isolated fragments in human-altered landscapes. Such fragments lose their diversity over time and, in the case of redwoods, may even lose the ability to grow new, giant trees. The Redwood Forest, written in support of Save-the-Redwood League's master plan, provides scientific guidance for saving the redwood forest by bringing together in a single volume the latest insights from conservation biology along with new information from data-gathering techniques such as GIS and remote sensing. It presents the most current findings on the geologic and cultural history, natural history, ecology, management, and conservation of the flora and fauna of the redwood ecosystem. Leading experts -- including Todd Dawson, Bill Libby, John Sawyer, Steve Sillett, Dale Thornburgh, Hartwell Welch, and many others -- offer a comprehensive account of the redwoods ecosystem, with specific chapters examining: the history of the redwood lineage, from the Triassic Period to the present, along with the recent history of redwoods conservation life history, architecture, genetics, environmental relations, and disturbance regimes of redwoods terrestrial flora and fauna, communities, and ecosystems aquatic ecosystems landscape-scale conservation planning management alternatives relating to forestry, restoration, and recreation. The Redwood Forest offers a case study for ecosystem-level conservation and gives conservation organizations the information, technical tools, and broad perspective they need to evaluate redwood sites and landscapes for conservation. It contains the latest information from ground-breaking research on such topics as redwood canopy communities, the role of fog in sustaining redwood forests, and the function of redwood burls. It also presents sobering lessons from current research on the effects of forestry activities on the sensitive faunas of redwood forests and streams. The key to perpetuating the redwood forest is understanding how it functions; this book represents an important step in establishing such an understanding. It presents a significant body of knowledge in a single volume, and will be a vital resource for conservation scientists, land use planners, policymakers, and anyone involved with conservation of redwoods and other forests.

This book was released on 2005 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest regeneration is a cornerstone of managing forests sustainably. Prompt and efficient regeneration gives society the benefits of wood products, as well as the economic wealth that obtaining and processing wood creates. Good reforestation habits provide more wood from less land and increased timber productivity means that demand for wood products can be met with less impact on non-wood uses of the forest. This symposium which was attended by nearly 200 professionals included participants from Canada, the United States, Europe, and Asia had as its focus the issue of forest regeneration which is a cornerstone of managing forests sustainably. Papers presented cover a range of topics related to reforestation within the broader categories of: the status of reforestation and afforestation around the world; nursery methodologies to produce target seedlings; planting and planting site treatments to optimize regeneration; and enhancing timber production and non-timber values through stand establishment.--Document.

This book was released on 2007 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to quantify forest disturbance processes and evaluate the influence of these processes on secondary hardwood forest communities on a section of the Cumberland Plateau in Tennessee. The specific objectives of this study were to: (1) reconstruct the disturbance history of a secondary hardwood forest using species composition, stand structure, tree-ring data, and soil charcoal analyses, (2) quantify canopy gap formation mechanisms, (3) document canopy gap characteristics, and (4) determine the forest response to small-scale disturbance events. This information is useful to understand the importance of localized disturbances on stand development and forest successional patterns. With the exception of one stand-wide disturbance in the early 1980s, the disturbance regime of the forest was characterized by localized, asynchronous events that occurred at variable spatial and temporal scales. Gap-scale disturbance events became frequent after about 40 years of forest development. The presence of soil charcoal indicated that fire had occurred in the Pogue Creek Natural Area in the past, but species composition and a lack of fire-scarred trees indicated that fire had not occurred during the development of the current stand. The majority of canopy gaps were caused by treefall (either windthrow or basal-shear) and half of all gaps were caused by the death of a Quercus individual. Gap ages ranged from 1 to 17 years with a mean of 7 years. Seasonality of death could be accurately determined for 17 gap makers and all but one of these trees died during the growing season. Strong wind associated with convective storms is the most probable disturbance agent in the forest. The fraction of land area in expanded gaps and true canopy gaps was 15% and 6%, respectively. The amount of land area in canopy gaps was highest for younger gaps and generally decreased with increased gap age. Most expanded and true canopy gaps had elliptical shapes and the majority of gaps were oriented perpendicular to slope contours. Significant positive relationships were documented between expanded gap size and the density of saplings, trees, and total stems. Only weak relationships existed between stem diversity and expanded gap size. Most of the canopy gaps documented were projected to close by lateral crown expansion rather than height growth of subcanopy individuals, but gaps still provided a means for understory trees to recruit to larger size classes. Over half of all trees located in true canopy gaps with intermediate crown classifications were Acer saccharum, A. rubrum, or Liriodendron tulipifera. Because the gaps documented were relatively small and close by lateral branch growth of perimeter trees, the most shade-tolerant A. saccharum has the greatest probability of becoming dominant in the canopy under the current disturbance regime. This study indicated that gap-scale disturbance processes have an influence on stand development and successional patterns of secondary hardwood forests in the absence of large-scale events.

Download or read book Wildland Fuel Fundamentals and Applications written by Robert E. Keane and published by Springer. This book was released on 2014-11-04 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new era in wildland fuel sciences is now evolving in such a way that fire scientists and managers need a comprehensive understanding of fuels ecology and science to fully understand fire effects and behavior on diverse ecosystem and landscape characteristics. This is a reference book on wildland fuel science; a book that describes fuels and their application in land management. There has never been a comprehensive book on wildland fuels; most wildland fuel information was put into wildland fire science and management books as separate chapters and sections. This book is the first to highlight wildland fuels and treat them as a natural resource rather than a fire behavior input. Moreover, there has never been a comprehensive description of fuels and their ecology, measurement, and description under one reference; most wildland fuel information is scattered across diverse and unrelated venues from combustion science to fire ecology to carbon dynamics. The literature and data for wildland fuel science has never been synthesized into one reference; most studies were done for diverse and unique objectives. This book is the first to link the disparate fields of ecology, wildland fire, and carbon to describe fuel science. This just deals with the science and ecology of wildland fuels, not fuels management. However, since expensive fuel treatments are being planned in fire dominated landscapes across the world to minimize fire damage to people, property and ecosystems, it is incredibly important that people understand wildland fuels to develop more effective fuel management activities.
Book Synopsis Response of Seedlings and Saplings to Canopy Gaps in Coastal Old Growth Forests by : Jennifer A. Passmore
Download or read book Response of Seedlings and Saplings to Canopy Gaps in Coastal Old Growth Forests written by Jennifer A. Passmore and published by . This book was released on 2007 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fine-scale disturbances involving the death of one to a few trees create gaps in the forest canopy and, where large-scale disturbances are rare, exert a dominant influence on community and population dynamics. I examine the natural regeneration and recruitment of seedlings and saplings following fine-scale, gap forming disturbances in old-growth stands within the Capilano, Seymour and Coquitlam River watersheds. I compared the abundance of western redcedar, western hemlock, and Pacific silver fir seedlings and saplings between plots located within and adjacent-to 20 gaps of known date of origin. I also destructively sampled seedlings and saplings of each species and applied dendroecological methods to determine the age of each sample, and to elucidate patterns of suppression and release in radial growth. My results support the paradigm of gap-scale canopy replacement. Seedlings and saplings were more abundant in gap versus forest environments, and exhibited increased rates of establishment and radial growth.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth release of trees following canopy disturbances is of interest to ecological scientists and forest managers. Using dendroecological techniques, I examined growth release of canopy and subcanopy trees following the formation of natural, fine-scale canopy gaps in old-growth, western red cedar-western hemlock forests of coastal British Columbia. I aimed to quantify detailed information on release of the three shade-tolerant tree species that constitute these stands: western red cedar (Thuja plicata), western hemlock (Tsuga heterophylla), and Pacific silver fir (Abies amabilis). As a first step, I calibrated the radial-growth averaging method to account for regional-scale variability and capture a more complete range of growth releases that may occur following the formation of fine-scale gaps in the study stands. A 25% threshold, 5-year moving average, and 10-year window emerged as appropriate parameters for detecting releases using radial-growth averaging. Basal area increment was also the most appropriate growth index for detecting releases. Establishing these empirically-based criteria was important for quantifying the magnitude and duration of releases. Tree diameter and growth rate prior to release were the most important predictors of the magnitude and duration of releases, but identity of the tree species and distance from the gap center were also important predictors. Western hemlock and Pacific silver fir were often growing slowly both in the canopy and subcanopy, giving them tremendous potential to release. For these species, releases were generally intensive and persistent. In contrast, western red cedar were often growing quickly both in the canopy and subcanopy, giving them less potential to release. Compared to western hemlock and Pacific silver fir, western red cedar releases were less intensive and persistent. Patterns related to distance from the gap center emerged for trees growing along the north-south axis of gaps. Regardless of species, increa.
