Book Description
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 Description
Riparian buffers are a widely promoted best management practice for improving stream health and habitat benefits, including reducing instream nitrogen (N) loading. There is a large spatial variability in N removal within riparian buffers, which can largely be explained by buffer width and variations in subsurface water flux. Variable-width buffers are recommended, but there are no simple models to guide restoration efforts, and fixed-width buffers are the norm, also because they are easier to implement and regulate. The goal of our research is to improve riparian buffer restoration for reducing N loading. We developed a simple spatially explicit GIS model that estimates the N removal within riparian buffers and that can prioritize locations for variable-width buffers. The innovative part of our model is the spatially explicit prioritization scheme accounting for removal in both upslope and downslope areas. We tested the model on a watershed in the Mid-Atlantic Piedmont and we applied the model to compare fixed-width and variable-width buffers. Our results show that variable-width buffers require less area to reach N load reduction goals, compared to the fixed-width buffers. Our model will aid watershed managers to make well-informed decisions for prioritizing buffer placement and to maximize N removal and improve water quality.

A preliminary test of RNAM indicated that each of the sub-models is capable of producing reasonably accurate estimations of percent nutrient reduction. RNAM-nitrogen, however, produced inconsistent estimates of nitrogen reduction at higher levels. More data is needed to calibrate and validate RNAM.

Book Description
This annotated bibliography contains 1,905 citations from professional journals, symposia, workshops, proceedings, technical reports, and other sources. The intent of this compilation was to: (1) assemble, to the extent possible, all available and accessible publications relating to riparian management within a single source or document; (2) provide managers, field biologists, researchers, and others, a point of access for locating scientific literature relevent to their specific interest; and (3) provide, under one cover, a comprehensive collection of annotated publications that could dessiminate basic information relative to the status of our knowledge.

Book Description
The production of food and energy interfere with the natural nitrogen cycle of the earth. Many of these changes are beneficial, while others are detrimental to societies and the environment. The changing nature of nitrogen in the global environment crosses scientific disciplines, geographical boundaries and political divisions and challenges the creative minds of natural and social scientists, economists, engineers, business leaders and planners. The papers in this book give readers a panoramic view of the changing nature of reactive nitrogen in the global environment, enabling them to make better choices about nitrogen management in food production and consumption, energy production and use, and environmental protection.
