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.

This book was released on 1996 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late 1970s, approximately 400 miles of streams were inventoried by the Prineville District of the Bureau of Land Management for in-stream and riparian condition. During the summer of 1994, the riparian portion of the survey was repeated on 17 of the original streams miles, contained within 11 stream sections where grazing strategies had been altered. This project was a case study designed to evaluate efficiency of the original methods and identify factors involved in individual stream responses. The streams selected to be resurveyed varied in community types present, gradient, elevation, grazing system, disturbance history, influence of beaver, and restoration efforts. Community types were identified by their major components (grass-shrub, sedge-rush) and measured for length and width. Length of stream bank damage was estimated and causes noted. Stream sections were surveyed between matching points for the 1976-78 and 1994 surveys. Most streams had increases in riparian area and decreases in bank damage and lengths of cutbanks, suggesting an upward trend in condition. The bank damage, riparian area, and community identification portions of the survey were identified as useful though composition measurements were determined to be less dependable and repeatable.

This book was released on 1996 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riparian zones are critical habitats for management because of their importance for both cattle production and wildlife, and a high potential for resource conflicts. Riparian management should address habitat and microhabitat features that sustain both livestock production and wildlife diversity. I conducted a study to determine how small mammal distributions and abundance differ among 3 structurally different riparian habitats in eastern Oregon. The 3 habitat types, herbaceous, discontinuous willow, and continuous willow, represent a range of habitats typical of riparian zones in central and eastern Oregon. I estimated small mammal population sizes in 9 trap grids placed in riparian zones using capture-recapture techniques. Four species of small mammals were captured during 7 trapping periods from August 1994 to September 1995. Small mammal distributions and population sizes of each species varied both within and among riparian pastures. Montane voles (Microtus montanus) were the most abundant species in all grids. Deer mice (Peromyscus maniculatus) had high population sizes in grids with low montane vole populations and moderate to high willow cover. Competition with voles appeared to occur in riparian habitats of Bear Valley, and influenced the distribution and numbers of deer mice. Western jumping mice (Zapus princeps) were captured at relatively low numbers and almost exclusively in continuous willow habitats. Vagrant shrews (Sorex vagrans) were captured on all grids, and population sizes were small. Haying negatively affected survival rates of voles. Biomass, vegetation height, and percent ground cover were the habitat variables most frequently associated with occurrence of montane voles in Bear Valley. The probability of occurrence of this species was positively correlated with these habitat variables. Deer mice probability of occurrence was positively correlated with percent ground cover, plant biomass, and soil moisture. Most deer mice captures occurred in continuous willow habitats, and the number of captures increased with willow basal cover (R2=0.7579, P
Download or read book Wildlife Habitats in Managed Rangelands written by Jack Ward Thomas and published by . This book was released on 1979 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riparian zones can be identified by the presence of vegetation that requires free or unbound water or conditions that are more moist than normal (fig. 1) (Franklin and Dyrness 1973, Minore and Smith 1971). Riparian zones can vary considerably in size and vegetative complex because of the many combinations that can be created between water sources (fig. 2) and physical characteristics of a site. Such characteristics include gradient, aspect, topography, soil, type of stream bottom, water quality, elevation, and plant community (Odum 1971). All riparian zones within managed rangelands of the western United States, however, have the following in common: (1) they create well-defined habitat zones within the much drier surrounding areas; (2) they make up a minor proportion of the overall area; (3) they are generally more productive in terms of biomass-plant and animal-than the remainder of the area; and (4) they are a critical source of diversity within rangelands (fig. 3). Carothers (1977), Carothers and Johnson (19751, and Curtis and Ripley (1975) have prepared summary papers on the subject of riparian habitats as associated with both range and forest areas.
