Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act mandates the implementation of approved best management practices (BMPs) in all states to control non point source pollution. Water control and revegetation BMPs are commonly used to control erosion and sedimentation from forest roads. The main objective of this study was to assess the adequacy of broad-based dip construction and vegetation establishment. In 2006, 19 gravel haul roads with broad-based dips in the Monongahela National Forest, West Virginia were examined to determine if they adhered to Forest specifications for cut depth and dip outslope. Data on the azimuth, contributing road lengths, slopes of the contributing lengths, landscape position of the dips, wheel track depths and soil texture of the road bed materials also were recorded to identify variables that explained variation in cut depth and dip outslope. Only about 22 percent of the dips met allowable cut depth specifications, and just over half of the dip slopes met the 2-5 percent outslope specifications. Cut depth was explained primarily by road geometry variables, suggesting that proper construction is important to ensure the dip impedes longitudinal drainage down the road while remaining traversable. Dip slope was affected by environmental and use variables, so maintenance during and following use is critical to ensure proper short- and long-term drainage. Vegetative growth along the entire cutbank of Forest Service road 973 within a managed watershed in the Left Fork of Clover Run on the Cheat District of the Monongahela National Forest in Tucker County, West Virginia was monitored from 2004 through 2006 using photograph analysis. Four sets of photographs were taken over the three years, two of which were taken in 2005 before and after timber harvesting. Percent vegetation establishment along the cutbank for each year was calculated to determine if there were significant differences in vegetative cover over time. Aspect and cutbank slope also were examined to determine if they influenced vegetation establishment. Cutbank slope was not a significant variable, but aspect was. South-facing aspects had significantly less vegetative cover than NE-, E-, WNW-, and NW-aspects. Timber felled onto the cutbank and poor initial seed establishment had a significant effect on vegetation establishment. Trees felled onto the cutbank and road can be deleterious to established vegetation, thus, trees slated for harvest that could impact the road prism should be removed before seeding, or directionally felled away from the road prism. Additionally, if vegetation on cutbanks is not established, soil should be mulched and vegetation coverage should be monitored.

This book was released on 2012-12-06 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: We must enhance the effectiveness ofland stewardship and management of the world's natural resources to meet a growing global population's need for conservation, sustainable development, and use of land, water, and other natural resources. Ecosystem-based, mul tiple-use land stewardship is necessary when considering the present and future uses ofland, water, and other natural resources on an operationally efficient scale. We need holistically planned and carefully implemented watershed management practices, projects, and pro grams to accommodate the increasing demand for commodities and amenities, clear water, open space, and uncluttered landscapes. An international conference in Tucson, Arizona, from March 13 to 16, 2000, examined these needs and increased people's awareness of the contributions that ecosystem-based, multiple-use watershed management can make to future land stewardship. The conference was sponsored by the School of Renewable Natural Resources, University of Arizona; the College of Agriculture, University of Arizona; the Rocky Mountain Research Station, USDA Forest Service; the Research Center for Conservation of Water Resources and Disaster Pre vention, National Chung-Hsing University, Taiwan; the Department of Forest Resources, University of Minnesota; the Center for Integrated Natural Resources and Agriculture Man agement, University of Minnesota; the Centro de Investigaciones Biologicas del Noreste, Mexico; the International Arid Lands Consortium; the USDA Natural Resources Conserva tion Service; the Bureau of Land Management of the Department of the Interior; the Salt River Project, Phoenix, Arizona; the Southern Arizona Chapter, Southwestern Section of the Society of American Foresters; and IUFRO Working Party 8. 04. 04, Erosion Control by Watershed Management.

Download or read book Management of Mountain Watersheds written by Josef Krecek and published by Springer Science & Business Media. This book was released on 2012-04-24 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book aims to address the interdisciplinary targets of watershed management in mountain regions based on the current knowledge of the subject. The focus of the book is particularly on monitoring, research, and modelling the interactions between the climate, water cycle, and aquatic ecosystem. The issues of watershed management in mountain regions in different parts of Europe, Africa, America and Asia have been the central theme of the book, which is basically divided into five sections: Institutional aspects in control of mountain regions; Stream-flow processes in mountain catchments; Water chemistry and biota in mountain streams and lakes; Effects of forest practices and climate change on hydrological phenomena; and Soil conservation and control of floods and landslides. The contributions have been peer-reviewed and the interdisciplinary team of authors includes experts from the specialised areas of geography, hydrology, chemistry, biology, forestry, ecology, economy and sociology. The practical applications and management strategies mentioned in the book, deal with the integrated resource management approach, based on the compromise between the development, conservation/ protection of the nature. Finally, the socio-economic and cultural aspects, and ecosystem prevalent in a mountain catchment are discussed in detail.

This book was released on 2021-08-24 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many people worldwide lack adequate access to clean water to meet basic needs, and many important economic activities, such as energy production and agriculture, also require water. Climate change is likely to aggravate water stress. As temperatures rise, ecosystems and the human, plant, and animal communities that depend on them will need more water to maintain their health and to thrive. Forests and trees are integral to the global water cycle and therefore vital for water security – they regulate water quantity, quality, and timing and provide protective functions against (for example) soil and coastal erosion, flooding, and avalanches. Forested watersheds provide 75 percent of our freshwater, delivering water to over half the world’s population. The purpose of A Guide to Forest–Water Management is to improve the global information base on the protective functions of forests for soil and water. It reviews emerging techniques and methodologies, provides guidance and recommendations on how to manage forests for their water ecosystem services, and offers insights into the business and economic cases for managing forests for water ecosystem services. Intact native forests and well-managed planted forests can be a relatively cheap approach to water management while generating multiple co-benefits. Water security is a significant global challenge, but this paper argues that water-centered forests can provide nature-based solutions to ensuring global water resilience.
