Download or read book Effects of Flooding and Tamarisk Removal on Habitat for Sensitive Fish Species in the San Rafael River Utah written by Daniel Louis Keller and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Part I of this report is focused on assessment of habitat changes on the San Rafael River after the abnormally high water year in 2011. Having habitat data and aerial imagery collected in 2010 (pre-flood) provided an opportunity to assess how a flood of this magnitude changed river habitat. In 2011 we commissioned a second aerial flight of the San Rafael River to serve as post flood imagery, then used Geographic Information Systems (GIS, ArcMap 10) to analyze river changes due to tamarisk removal and flooding. Our tamarisk removal project appears to have increased the potential for spring floods to diversify river habitat. The lack of complex habitat (pools, riffles, backwaters) is a limiting factor for native fish in the lower San Rafael River. Part I of this report also includes investigations into the importance of large woody debris (LWD) in creation of complex river habitat. Pools, riffles, and backwaters occurred more frequently within 30 m up and down stream of LWD piles (LWD buffers) compared to areas within 30 m of random points (random buffers). In addition to a greater number of pools around LWD, the pools inside LWD buffers were also significantly larger than those associated with the random buffers. The size of riffle and backwater habitat was not significantly different between the LWD buffers and the random buffers. LWD piles strongly influence the formation and distribution of complex habitat along the lower San Rafael River. Due to the importance of LWD in creating complex habitat and thermal refuge, several management options are discussed that would increase the LWD in the San Rafael River. Part I primarily covers the ecological component of this study, however the recommendations section of Part I discusses some of the policy and economic issues concerning restoration of the San Rafael River. Part II of the report will include human dimension, policy, and economic aspects of restoration efforts on the San Rafael River. Here we evaluate how water use could be impacted by further declines in native fish species and how potential listing of the 0́8three species0́9 would affect water users in the San Rafael River Drainage. The roundtail chub (Gila robusta) has been petitioned for listing under the Endangered Species Act in the Lower Colorado Basin. If roundtail chub were listed in the Upper Colorado Basin, the San Rafael River could be listed as critical habitat for recovery of the species. Part II also consists of a literature review of the current research available on the San Rafael River. The literature review is a synthesis of past research that illustrates the importance and need for restoration of the San Rafael River. Part II also identifies future research needs, such as evaluating the reintroduction of beaver as a restoration technique. This section will also discuss the pros and cons of current and proposed management practices, as well as identify how changes in local water policy and management could benefit native fish populations of the San Rafael River. Many of the proposed management practices such as installing more efficient irrigation systems, and working with water users to coordinate release of water in the spring time, will assist in the large undertaking of providing more flows for the benefit of native fish. The economic and ecological aspects of various tamarisk control methods is discussed with costs given for the current methods of tamarisk control being used on the San Rafael River.
Download or read book Renewing Our Rivers written by Mark K. Briggs and published by University of Arizona Press. This book was released on 2021-01-05 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our rivers are in crisis and the need for river restoration has never been more urgent. Water security and biodiversity indices for all of the world’s major rivers have declined due to pollution, diversions, impoundments, fragmented flows, introduced and invasive species, and many other abuses. Developing successful restoration responses are essential. Renewing Our Rivers addresses this need head on with examples of how to design and implement stream-corridor restoration projects. Based on the experiences of seasoned professionals, Renewing Our Rivers provides stream restoration practitioners the main steps to develop successful and viable stream restoration projects that last. Ecologists, geomorphologists, and hydrologists from dryland regions of Australia, Mexico, and the United States share case studies and key lessons learned for successful restoration and renewal of our most vital resource. The aim of this guidebook is to offer essential restoration guidance that allows a start-to-finish overview of what it takes to bring back a damaged stream corridor. Chapters cover planning, such emerging themes as climate change and environmental flow, the nuances of implementing restoration tactics, and monitoring restoration results. Renewing Our Rivers provides community members, educators, students, natural resource practitioners, experts, and scientists broader perspectives on how to move the science of restoration to practical success.
Download or read book Western Water A to Z written by Robert R. Crifasi and published by University Press of Colorado. This book was released on 2023-01-20 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Western Water A to Z is the first ever field guide to Western water. Reinventing this twentieth-century genre for a twenty-first-century audience, Robert R. Crifasi answers questions about rivers, water projects, the culture of water, the ecosystems water projects have created or destroyed, and the reliance of cities, farms, and industries on this critical resource. Organized as a collection of terms, the book addresses the most salient water issues and provides helpful background information regarding their origins and implications. Photographs serve a vital role in the cultural dialogue on water and stand as an equal partner to the text. Each subject is covered in about one page and is accompanied by one or two striking images from famous photographers like Margaret Bourke-White, Carleton E. Watkins, Arthur Rothstein, William Henry Jackson, and Dorothea Lang as well as Crifasi’s own work. Water often finds itself at the center of our cultural discourse in art, cinema, and literature, which play essential roles in shaping our understanding and experience of Western water. Crifasi also engages personalities that are nearly synonymous with Western water—John Wesley Powell, Elwood Mead, and Floyd Dominy, among others—to show how their lives intertwined with and often influenced the course of water development across the region. Travelers, adventurers, students, and anyone interested in water will find Western Water A to Z a handy and entertaining reference guide.

This book was released on 2011 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: PUBLIC ABSTRACT: Native fishes of the Colorado River Basin have experienced dramatic reductions in range and abundance as a result of extensive human alterations to the basin's waterways. Many of these native fishes are federally listed under the Endangered Species Act, while several others are subject to range-wide conservation agreements between state and federal management agencies. Three of the native species subject to range-wide conservation agreements are the flannelmouth sucker, bluehead sucker, and roundtail chub (hereafter, the "three species"). Each of the "three species" is still found in the San Rafael River of southeastern Utah, which has experienced habitat degradation and non-native species establishment representative of many desert streams. In this study, I examined the effects of non-native species on the food web structure and relative growth rates of the "three species" (Chapter 2) in two sections of the river characterized by the presence and absence of non-native fish. I found that the presence of non-native species lengthens the food chain, presenting new predators and competitors to the 'three species.' However, I found no evidence of reduced growth in the presence of these non-native fishes, likely due to movement of individuals of the "three species" between the two sections of river. Secondly, I developed a model to identify and rank limiting factors to the "three species" along the continuum of the lower river. Finally, I used this model to simulate and predict the relative effect of different restoration actions at different locations along the river on the abundance of the 'three species.' These models predicted that removal of non-native fishes and the restoration of long stretches of suitable habitat would be most beneficial to the 'three species.' Models such as those developed in this study can be useful for management agencies to prioritize restoration efforts to ensure the persistence of the "three species" both in the San Rafael River and throughout their historic range.
Download or read book Standing between Life and Extinction written by David L. Propst and published by University of Chicago Press. This book was released on 2021-02-15 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: North American deserts—lands of little water—have long been home to a surprising diversity of aquatic life, from fish to insects and mollusks. With European settlement, however, water extraction, resource exploitation, and invasive species set many of these native aquatic species on downward spirals. In this book, conservationists dedicated to these creatures document the history of their work, the techniques and philosophies that inform it, and the challenges and opportunities of the future. A precursor to this book, Battle Against Extinction, laid out the scope of the problem and related conservation activities through the late 1980s. Since then, many nascent conservation programs have matured, and researchers have developed new technologies, improved and refined methods, and greatly expanded our knowledge of the myriad influences on the ecology and dynamics of these species. Standing between Life and Extinction brings the story up to date. While the future for some species is more secure than thirty years ago, others are less fortunate. Calling attention not only to iconic species like the razorback sucker, Gila trout, and Devils Hole pupfish, but also to other fishes and obscure and fascinating invertebrates inhabiting intermittent aquatic habitats, this book explores the scientific, social, and political challenges of preserving these aquatic species and their habitats amid an increasingly charged political discourse and in desert regions characterized by a growing human population and rapidly changing climate.

Download or read book Southwestern Desert Resources written by William L. Halvorson and published by University of Arizona Press. This book was released on 2023-01-17 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The southwestern deserts stretch from southeastern California to west Texas and then south to central Mexico. The landscape of this region is known as basin and range topography featuring to “sky islands” of forest rising from the desert lowlands which creates a uniquely diverse ecology. The region is further complicated by an international border, where governments have caused difficulties for many animal populations. This book puts a spotlight on individual research projects which are specific examples of work being done in the area and when they are all brought together, to shed a general light of understanding the biological and cultural resources of this vast region so that those same resources can be managed as effectively and efficiently as possible. The intent is to show that collaborative efforts among federal, state agency, university, and private sector researchers working with land managers, provides better science and better management than when scientists and land managers work independently.
