Download or read book Post fire Treatment Effectiveness for Hillslope Stabilization written by Peter R. Robichaud and published by . This book was released on 1998 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis of post-fire treatment effectiveness reviews the past decade of research, monitoring, and product development related to post-fire hillslope emergency stabilization treatments, including erosion barriers, mulching, chemical soil treatments, and combinations of these treatments. In the past ten years, erosion barrier treatments (contour-felled logs and straw wattles) have declined in use and are now rarely applied as a post-fire hillslope treatment. In contrast, dry mulch treatments (agricultural straw, wood strands, wood shreds, etc.) have quickly gained acceptance as effective, though somewhat expensive, post-fire hillslope stabilization treatments and are frequently recommended when values-at-risk warrant protection. This change has been motivated by research that shows the proportion of exposed mineral soil (or conversely, the proportion of ground cover) to be the primary treatment factor controlling post-fire hillslope erosion. Erosion barrier treatments provide little ground cover and have been shown to be less effective than mulch, especially during short-duration, high intensity rainfall events. In addition, innovative options for producing and applying mulch materials have adapted these materials for use on large burned areas that are inaccessible by road. Although longer-term studies on mulch treatment effectiveness are on-going, early results and short-term studies have shown that dry mulches can be highly effective in reducing post-fire runoff and erosion. Hydromulches have been used after some fires, but they have been less effective than dry mulches in stabilizing burned hillslopes and generally decompose or degrade within a year.

Download or read book Pines and Their Mixed Forest Ecosystems in the Mediterranean Basin written by Gidi Ne'eman and published by Springer Nature. This book was released on 2021-10-12 with total page 744 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost 20 years after the first MEDPINE book "Ecology, biogeography and management of Pinus halepensis and P. brutia forest ecosystems in the Mediterranean basin "(Ne'eman and Trabaud, 2000) was published, this new book presents up-to-date and state of the art information, covering a wide range of topics concerning Mediterranean pine trees growing in native and planted forests, their ecosystems and management. This will be an essential source of scientific information for learning, exploring planning and managing mediterranean pine and mixed forests. We focus on: genetics, adaptation, distribution and evolution; ecophysiology and drought resistance; pine and mixed forest ecosystems; forest dynamics biodiversity and biotic interactions; fire ecology; ecosystem services and policy; afforestation and management; all under the effect of global climate change. While forests are studied mainly in temperate and tropical zones, in the light of current climate change, focusing on Mediterranean forests growing in semi-humid to semi-arid zones is more important than ever. This book will include mostly review chapters (and two outstanding case studies) contributed by leading scientists, foresters and managers, and will serve as a scientific textbook for students of biology, agriculture and forestry, researchers of ecology forestry and related fields, forest managers, policy and decision makers.

Download or read book Impact of Farmland Abandonment on Water Resources and Soil Conservation written by Noemí Lana-Renault and published by MDPI. This book was released on 2020-12-29 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Farmland abandonment is one of the major land use changes occurring in many rural territories, especially in mountainous regions. Without intervention (passive land management), farmland abandonment leads to an expansion of shrubs and forest on formerly cultivated hillslopes and grazing areas. All these land use changes affect the hydrological and geomorphological dynamics of slopes and channels, having important implications for water resources and soil conservation. However, the heterogeneity of abandoned scenarios complicates the assessment of farmland abandonment on water resources and soil conservation. In this Special Issue, we will publish papers that examine the hydrological and geomorphological consequences of farmland abandonment in one (or several) of these abandoned scenarios. Our final purpose is to help water and land managers to select the most sustainable strategy (in terms of water resources and soil conservation) for the land management of marginal rural areas.

Available in PDF, EPUB and Kindle. Book excerpt: Contemporary soil science and conservation methods of effective forestry Forests and the soils that serve as their foundation cover almost a third of the world’s land area. Soils influenced by forest cover have different properties than soils cultivated for agricultural use. Ecology and Management of Forest Soils provides a clear and comprehensive overview of the composition, structure, processes, and management of the largest terrestrial ecosystem. From composition and biogeochemistry to dynamics and management, this essential text enables readers to understand the vital components of sustainable, long-term forest soil fertility. The interaction of trees, animals, microbes, and vegetation alter the biology and chemistry of forest soils—these dynamics are also subject to human management, requiring conservationists to be conversant in the philosophy and methods of soil science. Now in its fifth edition, this classic text includes new coverage of uptake of organic nitrogen in forests, 15N retention studies, the effects of N additions on C accumulation, evidence-based examples of the dynamics of soils, and more. Extensive updates and revisions to topics such as spatial implications of megafires, long‐term organic matter accumulation, soil characterization, and molecular soil measurement techniques reflect contemporary research and practices in the field. This informative overview of forest soils integrates clear and accurate descriptions of central concepts and logically organized chapters to provide readers with foundational knowledge of major soil features, processes, measurement techniques, and management methods. This authoritative survey of the management and ecology of forest soils: Offers full-color photographs and illustrations, real-world examples and case studies, and clear overviews to each topic Presents up-to-date and accessible coverage of contemporary forest science literature and research Addresses topical issues relevant to areas such as ecology, forest management, conservation, and government policy Provides a comprehensive, global perspective on forest soils, from tropical to temperate to boreal Presents balanced coverage of soil science principles and their practical application to forest management Ecology and Management of Forest Soils offers students in areas of soil science and forestry, natural resource and environmental management, ecology, agronomy, and conservation an invaluable overview of the field, while providing forestry professionals an efficient and current work of reference.
Download or read book Fire Effects on Soil Properties written by Paulo Pereira and published by CSIRO PUBLISHING. This book was released on 2019-02-01 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildland fires are occurring more frequently and affecting more of Earth's surface than ever before. These fires affect the properties of soils and the processes by which they form, but the nature of these impacts has not been well understood. Given that healthy soil is necessary to sustain biodiversity, ecosystems and agriculture, the impact of fire on soil is a vital field of research. Fire Effects on Soil Properties brings together current research on the effects of fire on the physical, biological and chemical properties of soil. Written by over 60 international experts in the field, it includes examples from fire-prone areas across the world, dealing with ash, meso and macrofauna, smouldering fires, recurrent fires and management of fire-affected soils. It also describes current best practice methodologies for research and monitoring of fire effects and new methodologies for future research. This is the first time information on this topic has been presented in a single volume and the book will be an important reference for students, practitioners, managers and academics interested in the effects of fire on ecosystems, including soil scientists, geologists, forestry researchers and environmentalists.
Download or read book Advances in Natural Hazards and Hydrological Risks Meeting the Challenge written by Francisco Fernandes and published by Springer Nature. This book was released on 2020-01-02 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the proceedings of the 2nd International Workshop on Natural Hazards (NATHAZ'19), held in Lajes do Pico, Pico Island, Azores in 2019. Natural hazards constitute the threat of a naturally occurring event having a negative effect on human beings. These effects are often called natural disasters. Among the natural hazards and potential disasters to be considered are: earthquakes, volcanic eruptions, landslides, subsidence, floods, droughts and coastal erosion. In addition, there are anthropogenic hazards that occur as a result of human interactions with the environment. They include technological hazards, which occur due to exposure to hazardous substances in the environment. Grasping the behaviour of natural systems requires a comprehensive understanding of climatology, geology and hydrology data and dynamics. Thus, it is important to conduct hazard and risk assessment studies for meaningful hazard mitigation. Further, the book demonstrates that an accurate understanding of natural systems and interactions between engineering and natural resources is of vital significance to the entire socio-economic sector. This volume offers an overview of natural hazards in model regions in Europe, America, and Atlantic islands. Providing new insights on the characterisation, assessment, protection and modelling of geological hazards, water systems, urban areas and coastal zones, it represents a valuable resource for all researchers and practitioners in the fields of Geosciences, Hydrology, Water Resources, Natural Hazards, Environments and Engineering. Main topics include:1. Natural Hazards and Disasters2. Sustainable Water Systems and Climate Change3. Technological Hazards and Engineering Design
Download or read book Evaluating the Effectiveness of Postfire Rehabilitation Treatments written by Peter R. Robichaud and published by . This book was released on 2000 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spending on postfire emergency watershed rehabilitation has increased during the past decade. A west-wide evaluation of USDA Forest Service burned area emergency rehabilitation (BAER) treatment effectiveness was undertaken as a joint project by USDA Forest Service Research and National Forest System staffs. This evaluation covers 470 fires and 321 BAER projects, from 1973 through 1998 in USDA Forest Service Regions 1 through 6. A literature review, interviews with key Regional and Forest BAER specialists, analysis of burned area reports, and review of Forest and District monitoring reports were used in the evaluation. The study found that spending on rehabilitation has increased to over $48 million during the past decade because the perceived threat of debris flows and floods has increased where fires are closer to the wildland-urban interface. Existing literature on treatment effectiveness is limited, thus making treatment comparisons difficult. The amount of protection provided by any treatment is small. Of the available treatments, contour-felled logs show promise as an effective hillslope treatment because they provide some immediate watershed protection, especially during the first postfire year. Seeding has a low probability of reducing the first season erosion because most of the benefits of the seeded grass occurs after the initial damaging runoff events. To reduce road failures, treatments such as properly spaced rolling dips, water bars, and culvert reliefs can move water past the road prism. Channel treatments such as straw bale check dams should be used sparingly because onsite erosion control is more effective than offsite sediment storage in channels in reducing sedimentation from burned watersheds. From this review, we recommend increased treatment effectiveness monitoring at the hillslope and sub-catchment scale, streamlined postfire data collection needs, increased training on evaluation postfire watershed conditions, and development of an easily accessible knowledge base of BAER techniques.
