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: The Colorado River had one of the most unique fish communities in the world. Seventy-five percent of those species were found nowhere else in the world. Settlement of the lower basin brought dramatic change to both the river and its native fish. Those changes began more than 120 years ago as settlers began stocking nonnative fishes. By 1930, nonnative fish had spread throughout the lower basin and replaced native communities. All resemblance of historic river conditions faded with the construction of Hoover Dam in 1935 and other large water development projects. Today, few remember what the Colorado River was really like. Seven of the nine mainstream fishes are now Federally-protected as endangered. Federal and state agencies are attempting to recover these fish. However, progress has been frustrated due to the severity of human impact. This report represents testimony, old descriptions, and photographs describing the changes that have taken place in hopes that it will provide managers, biologists, and the interested public a better appreciation of the environment that shaped these unique fish.

Download or read book River and Desert Plants of the Grand Canyon written by Kristin Huisinga and published by Mountain Press. This book was released on 2006 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Grand Canyon's isolation, great elevational range, and position at the convergence of three North American deserts--the Mojave, Sonoran, and Great Basin--have created unique habitats for an unusual assemblage of plants. Some grow only at seeps and springs, others emerge from cracks in the bedrock, and some live only in the Grand Canyon--for example, Roaring Springs prickly poppy and Grand Canyon flaveria. River and Desert Plants of the Grand Canyon, the first comprehensive field guide devoted to plants that live below the canyon rims, is bursting with beautiful color photographs and detailed line drawings of more than 250 ferns, grasses, forbs, shrubs, and trees. Narratives organized by life form and common family name describe each plant and its natural history, and thumbnail photographs arranged by flower color and shape offer a key for easy identification. Essays by contributing experts explore such topics as Grand Canyon ecology, desert-plant adaptations, biological soil crusts, plant pollination, invasive species, and domesticated plants of the canyon's indigenous people.
