This book was released on 2011 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stream riparian zones are ecotones between terrestrial and aquatic environments. Studying these areas in urban environments is important since they lie adjacent to stream water supplies. I conducted a study of riparian woody and groundcover vegetation along urban, suburban, and rural streams (land-use designations based on % impervious surface) to assess how cities are affecting plant community structure. I also studied riparian soil gas flux (carbon dioxide, methane, and nitrous oxide) in relation to water table depth and groundwater nutrient concentrations spanning a 10-month period (January to October, 2008). I found distinct woody and groundcover communities associated with proportion of impervious surface surrounding the research sites. These communities differed regarding diversity and proportion of native, exotic, and wetland species distributions. The most urban communities generally had lower species richness, more exotic species, and fewer wetland species when compared to rural areas. Urban areas also exhibited the highest streambanks and lowest water tables. Carbon dioxide gas flux rates were higher in urban areas, but methane and nitrous oxide fluxes did not respond uniformly to site differences as classified by proportion of impervious surface. Methane and nitrous oxide differences, in addition to seasonal variability, were more greatly affected by local site level differences in substrate and nutrient ratios as well as soil moisture.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Riparian corridor protection through zoning ordinances is a common best management practice to protect riparian ecosystems and function. These zoning ordinances protect riparian ecosystems by establishing setback distances where land use activities are prohibited. While management of protected riparian corridors are widely studied, recommendations for riparian corridor width vary and are often site specific. The variability of corridor widths presents a challenge to riparian corridor implementation, in addition to balancing economic needs with natural resource protection. This study evaluates the effects of land use on riparian corridors and compares the Riparian Corridor Combining Zone ordinance in Sonoma County to other government agencies and scientific literature recommendations for riparian corridor management, specifically width recommendations. In Sonoma County, the dominant land use categories throughout the county are agricultural cultivation and urban development. Agricultural cultivation and urban development alter stream channels, increase erosion, impair water quality, modify riparian vegetation, and threaten aquatic and terrestrial wildlife. To protect riparian areas and adjacent habitat form land use activities, Sonoma County adopted the Riparian Corridor Combining Zone ordinance. The Riparian Corridor Combining Zone ordinance implemented riparian corridor widths within the range recommended by other government agencies and scientific literature for optimal riparian function. However, the ordinance allows exceptions for agricultural cultivation, which may influence the effectiveness of riparian corridor functions. Recommendations for riparian management in Sonoma County include an assessment on the current condition of riparian ecosystems, a new policy based on science that provides consistent riparian protection for all development types, increasing public education on the benefits of riparian ecosystems, and encouraging riparian restoration through incentive programs and new development projects.

Available in PDF, EPUB and Kindle. Book excerpt: This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

Available in PDF, EPUB and Kindle. Book excerpt: Protecting minimum riparian corridor widths is a common approach by government authorities seeking to mitigate impacts of urban development on riparian and aquatic ecosystems. However, little data exists to verify the efficacy of these policies for biodiversity conservation. This thesis presents research to this end thereby contributing to urban environmental planning practice. -- To promote ecological sustainability, scientific concepts of biodiversity and urban river function need to be connected closely with environmental policy. Following discussion of these themes, the relationship between biodiversity and corridor width was assessed by comparing ant and plant communities from 18 riparian corridors in the Ku-ring-gai Local Government Area, Sydney. Corridor width was not related to ant and plant species diversity but was related to the assemblage composition of both groups. However, substantial data variability remained unexplained. -- This variability was investigated through exploring relationships between biological and environmental data. Reserve perimeter:area ratio and the gradient of the hillslope were identified as significant predictors of ant and plant richness. Corridor width was the best predictor of plant composition overall due to increased habitat heterogeneity in wider corridors, while soil pH was the best predictor of streamside plant communities. Changes in plant composition were driven primarily by exotic plants. Ant composition was influenced by the proportion of adjacent road cover, vegetation type, and reserve connectivity. -- In response to these results the affect of land use on riparian ant communities was assessed through comparing urban and rural catchments in north-west Sydney. Surprisingly, no significant differences in ant diversity or composition were found, but ants responded the dominance of weeds within the riparian zone. -- This work highlights the complexity of biodiversity patterns in urban riparian systems and suggests that in addition to setting minimum corridor widths, managers should consider local and catchment-wide activities and promote active management of the riparian zone.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides a state-of-the-art, comprehensive overview of the expanding field of urban biodiversity. The field of urban biodiversity has emerged from within the broad discipline of urban ecology in the past two decades and is now a significant field in its own right. In view of this, the Routledge Handbook of Urban Biodiversity presents a thorough treatment of this field detailing the history of urban biodiversity, theoretical foundations, current state of knowledge, and application of that knowledge. The handbook is split into four parts: Part I: Setting the Stage for Urban Biodiversity Research and Practice Part II: Foundational Concepts and Theory in Urban Biodiversity Research Part III: Population and Community Ecology of Key Urban Taxa Part IV: Urban Biodiversity Practice: Management, Planning, and Design for Healthy Communities This volume contains interdisciplinary and global contributions from established and early career academics as well as professionals and practitioners, addressing two key fields in urban biodiversity: fundamental research focused on answering questions about the mechanisms explaining the distribution of species among and within cities; and applied research and work by practitioners to address concerns about urban biodiversity conservation, restoration, planning, design, and public involvement. This handbook is essential reading for students, academics, and professionals interested and working in the fields of urban biodiversity, ecology, nature conservation, urban planning, and landscape architecture.

Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for those with an academic, scientific and practical interest in river conservation and management. It provides an overview of how changes in legislation, policies, institutional responsibilities, science, technology, practical techniques and public perception have influenced how rivers have been managed over the past 20 years and the challenges that lie ahead during the next 20 years. The book is based on the international conference River Conservation and Management:20 Years On held at York. Thirty-one chapters, with contributions from North and South America, Europe, Asia and Australasia provide a wide-ranging perspective on this complex but profoundly important subject. Following an introduction that chronicles the most important contextual changes, the book is organized into four broad topics: Catchment management, ecosystem integrity and the threats to river ecosystems – this covers progress on understanding and addressing the pressures affecting rivers, many of which will be amplified by climate change and increasing human demands for water; Methods and approaches – illustrating some recent techniques that have been developed to assess condition and conservation status across different types of river; Recovery and rehabilitation – providing an insight into the principles, practice, public involvement and institutional networks that support and make improvements to modified river reaches; Integrating nature conservation into wider river management –demonstrating the importance of integrated planning, involvement of local communities and the use of adaptive management in achieving multiple environmental and economic benefits along rivers used for different purposes. The final chapter discusses the challenges faced in dealing with an uncertain future. More than 1200 different references and numerous web-site citations provide the reader with an invaluable source of knowledge on the subject area.
