This book was released on 2004 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widespread loss and degradation of riparian areas in the arid and semi-arid western United States has led to an increased interest in revegetation efforts aimed at restoring physical and ecological functions, such as streambank stabilization, wildlife habitat, and water quality protection (Briggs 1995) (Figure 1). However, successfully establishing riparian plant communities that can provide desired functions can be extremely challenging in arid areas that are remote from water supplies. In addition, plant establishment can be difficult in arid regions since many stream and riparian areas are characterized by infertile or highly saline soils, very low rainfall, narrow planting windows, dynamic/erosive hydrologic patterns that often scour soils holding planted vegetation, and prolific non-native plant species that tend to dominate the plant community.

This book was released on 2016 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: "TRB's National Cooperative Highway Research Program (NCHRP) Report 822: Evaluation and Assessment of Environmentally Sensitive Stream Bank Protection Measures evaluates and assesses existing guidelines for the design, installation, monitoring, and maintenance of environmentally sensitive stream bank stabilization and protection measures, and develops quantitative engineering design guidance for selected treatments. Updated design guidelines for three widely used treatments are presented: live siltation and live staking with a rock toe, vegetated mechanically stabilized earth, and vegetated rip rap. A compendium of field data, documentation, and photographs complement the report. The compendium is available as a DVD and available for download from TRB’s website as an ISO image."--Publisher’s description.

Download or read book How Will Hydrologic Change Alter Riparian Plant Communities of the Arid and Semi arid Southwest written by Andrea Florence Hazelton and published by . This book was released on 2011 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change has the potential to affect vegetation via changes in temperature and precipitation. In the semi-arid southwestern United States, heightened temperatures will likely lead to accelerated groundwater pumping to meet human needs, and altered storm patterns may lead to changes in flood regimes. All of these hydrologic changes have the potential to alter riparian vegetation. This research, consisting of two papers, examines relationships between hydrology and riparian vegetation along the Verde River in central Arizona, from applied and theoretical perspectives. One paper investigates how dominance of tree and shrub species and cover of certain functional groups change along hydrologic gradients. The other paper uses the Verde River flora along with that river's flood and moisture gradients to answer the question of whether functional groups can be defined universally. Drying of the Verde River would lead to a shift from cottonwood-willow streamside forest to more drought adapted desert willow or saltcedar, a decline in streamside marsh species, and decreased species richness. Effects drying will have on one dominant forest tree, velvet ash, is unclear. Increase in the frequency of large floods would potentially increase forest density and decrease average tree age and diameter. Correlations between functional traits of Verde River plants and hydrologic gradients are consistent with "leaf economics," or the axis of resource capture, use, and release, as the primary strategic trade-off for plants. This corresponds to the competitor-stress tolerator gradient in Grime's life history strategy theory. Plant height was also a strong indicator of hydrologic condition, though it is not clear from the literature if plant height is independent enough of leaf characteristics on a global scale to be considered a second axis. Though the ecohydrologic relationships are approached from different perspectives, the results of the two papers are consistent if interpreted together. The species that are currently dominant in the near-channel Verde River floodplain are tall, broad-leaf trees, and the species that are predicted to become more dominant in the case of the river drying are shorter trees or shrubs with smaller leaves. These results have implications for river and water management, as well as theoretical ecology.

Download or read book Riparian Vegetation Along Ephemeral Streams in Arid and Semi arid Environments and Implications for Clean Water Act Jurisdiction written by Aspen Manning and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act protects water quality, but its jurisdiction is limited to traditionally navigable waters and those tributaries that have relatively permanent flow (i.e., perennial flow) or a significant nexus (i.e., they significantly affect water quality in downstream waterways). In the arid southwestern United States, most streams are intermittent (flowing seasonally) or ephemeral (flowing only in response to precipitation), therefore they do not meet the relatively permanent standard. Determining whether a given ephemeral stream has a significant nexus to a downstream waterway is complicated, especially in arid regions where geomorphic evidence of flow events can persist for long periods of time. Riparian vegetation is used in field-based jurisdictional determinations, however the riparian vegetation of ephemeral streams in arid and semi-arid regions is understudied. This dissertation contributes to the existing empirical data on the riparian vegetation of ephemeral streams in the southwestern United States by examining the longitudinal spatial patterns of riparian communities along six ephemeral streams in New Mexico and Arizona using remote sensing. Normalized Difference Vegetation Index (NDVI) was used to determine the size and cover of riparian vegetation, which was then correlated to topographic, climatic, geomorphic, and streamflow characteristics. Riparian vegetation responds much more strongly to topographic and climatic variables than to streamflow variables. These results indicate that the riparian vegetation of ephemeral streams responds to different environmental factors compared to riparian vegetation along intermittent or perennial rivers. The results presented here can inform Clean Water Act policies regarding ephemeral streams in the southwestern United States.

Download or read book Sustainable Land Use in Deserts written by Siegmar-W. Breckle and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changing desert areas for land use implies a lot of ecological problems. These and related ones are dealt with in this book covering various interdisciplinary and international aspects. Large areas in arid and semi-arid regions are already polluted in various ways. One of the biggest problems is the anthropogenic salinization by inadequate means of agriculture and irrigation. Additionally, most arid areas in the world are dramatically overgrazed. Methods and practices of a sustainable land use in deserts are urgently needed in many arid regions. This book gives a broad survey on some of the affected regions of the world as well as some case studies from elsewhere (Aral Sea, Negev desert, Namib desert etc.). Thus, basic and applied sciences are brought together. Water management in deserts, grazing systems or reclamation of desertified areas are among the topics of this book, as well as social and economic aspects.
