This book was released on 2019 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most instances of browsing were recorded in GS treatments, followed by LD, HA, and HD treatments. In treatments with higher densities, browsing was less likely. As distance to watercourse and elevation increased, the probability of browsing diminished for both species. Like browsing, survival of planted seedlings was largely dependent on their position on the landscape. Seedlings planted on a southwest aspect had the lowest survival rates, while seedlings planted on a northeast aspect had nearly complete survival, regardless of species. Overall, Douglas-fir seedlings had higher mortality rates than redwood. Mortality was highest in GS, followed by HA and HD treatments, and was lowest in LD treatments. Seedling survival exhibited a rise-peak-fall pattern with increasing stand density. This pattern was the most distinct on southwest facing slopes. In general, dispersed treatments gave better results than aggregated and GS treatments when trying to maximize survival and minimize the occurrence of browsing. These results inform forest managers implementing a conversion towards multiaged management in coast redwood stands receiving partial harvesting without site preparation or herbicide treatment of re-sprouting hardwoods. Presumably, a reduction in below ground competition from hardwood control would enhance survival of planted seedlings. However, any enhancement of seedling growth and vigor may result in elevated browsing activity. Specific recommendations for management include planting extra seedlings on southern slopes and in stands of lower densities such as group selection openings (in anticipation of elevated mortality), and implementing seedling protection measures (e.g., shelters, repellant, fencing) near watercourses where browsing occurs most often.
Book Synopsis Optimizing Wildlife Habitat and Oak Regeneration in Bottomland Hardwoods Using Midstory Control and Partial Harvest by : James Cody Rainer
Download or read book Optimizing Wildlife Habitat and Oak Regeneration in Bottomland Hardwoods Using Midstory Control and Partial Harvest written by James Cody Rainer and published by . This book was released on 2015 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Timber and wildlife habitat management may be conflicting objectives, but both benefit from increasing light in bottomland forests through harvesting and midstory control, and a target residual basal area may be used to optimize both. Six areas were used to evaluate effects of partial harvest and midstory control on oak regeneration, diameter growth of residual trees, and white-tailed deer carrying capacity. Partial harvest treatments consisted of residual basal areas of 70ft2/ac (16.07m2/ha), 60ft2/ac (13.77m2/ha), 50ft2/ac (11.48 m2/ha), 40ft2/ac (9.18m2/ha), 30ft2/ac (6.89m2/ha), and untreated controls. All partial harvest areas received midstory control using injection with imazapyr. Available light was related to residual basal area (R2 = 0.808). Treatments with 50ft2/ac residual basal area exhibited the optimal amount of oak regeneration and white-tailed deer carrying capacity. Treatments with 30ft2/ac had greatest diameter growth. This research provided guidelines for managers that wish to optimize white- tailed deer habitat and oak regeneration.

Download or read book Ecosystems of California written by Harold Mooney and published by Univ of California Press. This book was released on 2016-01-19 with total page 1008 pages. Available in PDF, EPUB and Kindle. Book excerpt: This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.

Book Synopsis Continuous Cover Forestry by : Timo Pukkala
Download or read book Continuous Cover Forestry written by Timo Pukkala and published by Springer Science & Business Media. This book was released on 2011-10-14 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the majority of the world’s forest ecosystems are dominated by uneven-sized multi-species stands, forest management practice and theory has focused on the development of plantation monocultures to maximize the supply of timber at low cost. Societal expectations are changing, however, and uneven-aged multi-species ecosystems, selectively managed as Continuous Cover Forestry (CCF), are often believed to be superior to monocultures in addressing a wide range of expectations. This book presents methods which are relevant to CCF management and planning: analysing forest structures, silvicultural and planning, economic evaluation, based on examples in Europe, Asia, Africa and North and South America.

Book Synopsis Wildland Fuel Fundamentals and Applications by : Robert E. Keane
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.
Download or read book Silviculture written by Ralph D. Nyland and published by Waveland Press. This book was released on 2016-05-13 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silviculture: Concepts and Applications reflects a belief that all the tools of silviculture have a useful role in modern forestry. Through careful analysis and creative planning, foresters can address a wide array of commodity and nonmarket interests and opportunities while maintaining dynamic and resilient forests. A landowner’s needs, circumstances, and site conditions guide a silviculturist’s judgment and decision making in finding the best ways to integrate the biologic-ecologic, economic-financial, and managerial-administrative requirements at hand. The Third Edition of this influential text provides a foundational basis for rigorous discussion of techniques. The inclusion of numerous real-world examples and balanced coverage of past and current practices broadens the concept of silviculture and the ways that managers can use it to address both traditional and emerging interests in forests. A thorough discussion of new and proven interpretations increasingly directs the attention of foresters toward the role silviculture plays in creating, maintaining, rehabilitating, and restoring forests that can sustain an expanding variety of ecosystem services.
Book Synopsis Riparian Areas by : National Research Council
Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Synopsis Multiaged Silviculture by : Kevin Laughlin O'Hara
Download or read book Multiaged Silviculture written by Kevin Laughlin O'Hara and published by Oxford University Press, USA. This book was released on 2014 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest scientific and management information on multiaged silviculture, an emerging strategy for managing forestry systems worldwide. Over recent decades, forest science and management have tended to emphasize plantation silviculture. Whilst this clearly meets our wood production needs, many of the world's forests need to be managed far less intensively and more flexibly in order to maintain their natural ecosystem functions together with the values inherent in those processes. Developing multiaged management strategies for these complex forest ecosystems represents a global challenge to successfully integrate available science with sustainable management practices. Multiaged Silviculture covers the ecology and dynamics of multiaged stands, the management operations associated with regeneration, tending, and stocking control, and the implications of this strategy on production, genetic diversity, and stand health. It is primarily aimed at graduate level students and researchers in the fields of forestry and silviculture, but will also be of relevance and use to all professional foresters and silviculturists.
