Available in PDF, EPUB and Kindle. Book excerpt: Early in our history, rivers ran wild, and fish followed them according to their needs. In the ensuing years, America fueled the Industrial Revolution with resources of water, timber, minerals and wildlife. Early American innovation and progress were generally oblivious to their dependence on the fragile natural world. American resources seemed abundant without end. Then the fish began to disappear.

Book excerpt: I conducted a study to identify potential spawning habitat for anadromous salmonids above a 60-year-old hydropower dam in the headwaters of the North Umpqua River in Oregon. Like many other historical salmonid-bearing rivers, little documentation exists for anadromous fish presence above potential natural obstacles upstream of Soda Springs Dam. My prediction was that if migratory salmonids are allowed to move upstream of the dam using a new fish ladder they would utilize available upstream spawning habitat. I captured, radio-tagged, and transplanted wild adult summer steelhead, O. mykiss, above Soda Springs Dam and tracked daily movements for 1 year to observe habitat preferences. I also investigated evidence of historical anadromy throughout the North Umpqua River basin using stable isotope analysis of salmon-derived nitrogen (15N) in foliar samples from Douglas fir trees, P. menziesii, (>100 years old). I tested the hypothesis that I could identify undocumented, historical salmon spawning reaches above natural and anthropogenic obstacles based solely upon [delta]15N foliar deposition patterns. While tracking radio-tagged steelhead, I documented holding locations, the timing of spawning activities, and the outmigration of kelts. Tagged fish did not show any extensive movement in the river or tributaries above the dam. Most of the tagged adults showed incremental daily movements near the release site or downstream into the hydropower reservoir but did not travel further than 1 kilometer upstream in the main river channel. I recorded movements and localized activities that suggested some of the fish spawned and subsequently moved downstream towards the Pacific Ocean. My observations indicated that spawning behavior of tagged fish above Soda Springs Dam was delayed several weeks relative to fish spawning below the dam. There was no evidence from telemetry that any fish moved upstream in Fish Creek, the newly accessible habitat of interest in this project. My data suggest that steelhead will use restored habitat above dams, but that re-colonization activities are variable and may be affected by altered flow regimes within the restored habitat upstream of the dam and intra-specific density dependence. My stable isotope data indicated that the foliar [delta]15N deposition patterns were confounded with elevation. I documented potential "salmon-derived" false positives on the Umpqua National Forest above impassable waterfalls. Overall I found that foliar [delta]15N deposition patterns were highly variable and unexpectedly indicated a statistically significant negative correlation of foliar [delta]15N values with historical salmon presence. My linear mixed-effects modeling suggests that the presence of salmon is the most important indicator of foliar [delta]15N values, rather than the proximity of a sampled tree to stream flow above or below migratory barriers. I was not able to use the mixed effects model to identify previously undocumented salmon spawning habitat. My results from the foliar technique suggest that the method may not be universally applicable as has been previously suggested in the literature.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Download or read book Aquatic Habitats in Sustainable Urban Water Management written by Iwona Wagner and published by CRC Press. This book was released on 2008-01-07 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic habitats supply a wide range of vital ecosystem benefits to cities and their inhabitants. The unsustainable use of aquatic habitats, including inadequate urban water management itself, however, tends to alter and reduce their biodiversity and therewith diminish their ability to provide clean water, protect us from waterborne diseases and pollutants, keep urban areas safe from flooding, and support recreational ecosystem services and even the aesthetic enjoyment of our world. Aquatic Habitats in Sustainable Urban Water Management – the result of collaboration between UNESCO’s International Hydrological Programme and its Man and the Biosphere Programme – aims at improving our understanding of aquatic habitats, related ecosystem goods and services, and conservation and sustainable use – with a special focus on their integration into urban water management. The first part of this volume reviews basic concepts and challenges in urban aquatic habitats, as well as strategies for their management integration. The second part examines technical measures related to habitats management and rehabilitation, along with their incorporation into urban planning and their role in human health. The final part looks at current urban aquatic habitat issues and practical approaches to solving them through the lens of case studies from around the globe. Urban Water Series - UNESCO-IHP Following from the Sixth Phase of UNESCO’s International Hydrological Programme (2002–2007), the Urban Water Series – UNESCO-IHP addresses fundamental issues related to the role of water in cities and the effects of urbanization on the hydrological cycle and water resources. Focusing on the development of integrated approaches to sustainable urban water management, the Series should inform the work of urban water management practitioners, policy-makers and educators throughout the world.

Download or read book Monitoring Stream and Watershed Restoration written by Philip Roni and published by C A B International. This book was released on 2005 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable tourism is not a static target, but a dynamic process of change, a transition. This book considers how monitoring using indicators can assist tourism to make such a sustainability transition. It encourages the reader to view tourism from a broad, interdisciplinary perspective that draws on material from a wide range of sources including ecology, global change and the new and emerging field of sustainability science. The book explains why monitoring is important for different groups of stakeholders; public and private sector, NGOs and communities. It also examines important monitoring considerations such as what and where to measure, how much will monitoring cost and how the data can be presented. The book puts particular emphasis on indicator use and implementation. It highlights the process and techniques to develop and use indicators and then provides clear and detailed examples of monitoring in practice around the globe at different geographic scales.
