The demand for water resulting from massive population and economic growth in the southwestern U.S. overwhelmed traditional uses of riparian areas. As a consequence, many of these uniquely-structured ecosystems have been altered or destroyed. Within recent years people have become increasingly aware of the many uses and benefits of riparian zones a

Excerpt from Southwestern Riparian-Stream Ecosystems: Research Design, Complexity, and Opportunity The last area, a group of six streams, lies below the Mogollon Rim in central Arizona. Six perennial first order streams (pine, Dude, Bonita, Ellison, Christopher, and Horton creeks) issue from a major fault block (rinne and Medina Historically, these watersheds have been subjected to varied grazing and timber management practices. Pine Creek, at one end of the use spectrum, has not been grazed or logged for 25 years. In contrast, the Horton Creek watershed has been grazed season-long and continuously (may - October), and timber has been harvested on the watershed for years. The other watersheds are within grazing allotments and timber management areas that fall between these two extremes. Studies were initiated to establish baseline information to evaluate proposed changes in grazing management. In june 1990, a -ha natural wildfire (the Dude Fire) dramatically altered three of the six watersheds in this area. This natural event combined with eventful pretreatment data provided an excellent opportunity to evaluate natural and artificial effects on the structure and functioning of riparian areas.

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.

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.

Riparian Areas of the Southwestern United States: Hydrology, Ecology, and Management provides hydrologists, watershed managers, land-use planners, educators, policymakers, and non-governmental organizations with a comprehensive account of the multiple benefits and conflicts arising from the uniquely structured ecosystems of arid and semi-arid regions. The text describes the inhabitants of southwestern riparian ecosystems and addresses the research, planning, and management concerns for these fragile ecosystems in relation to the impacts of water and sediment flows, livestock grazing, and other human activities, and the maintenance of key wildlife and fish habitats.

Woody wetlands constitute a relatively small but extremely important part of the landscape in the southwestern United States. These riparian habitats support more than one-third of the regionÕs vascular plant species, are home to a variety of wildlife, and provide essential havens for dozens of migratory animals. Because of their limited size and disproportionately high biological value, the goal of protecting wetland environments frequently takes priority over nearly all other habitat types. In The Ribbon of Green, hydrologists Robert H. Webb, and Stanley A. Leake and botanist Raymond M. Turner examine the factors that affect the stability of woody riparian vegetation, one of the largest components of riparian areas. Such factors include the diversion of surface water, flood control, and the excessive use of groundwater. Combining repeat photography with historical context and information on species composition, they document more than 140 years of change. Contrary to the common assumption of widespread losses of this type of ecosystem, the authors show that vegetation has increased on many river reaches as a result of flood control, favorable climatic conditions, and large winter floods that encourage ecosystem disturbance, germination, and the establishment of species in newly generated openings. Bringing well-documented and accessible insights to the ecological study of wetlands, this book will influence our perception of change in riparian ecosystems and how riparian restoration is practiced in the Southwest, and it will serve as an important reference in courses on plant ecology, riparian ecology, and ecosystem management.
