Ecohydrology effects of an invasive grass (Phalaris arundinacea) on semi-arid riparian zones
<p>"Riparian areas (floodplains) provide key ecological functions that are linked to the ecohydrology however; they are particularly susceptible to invasion by alien species. In much of the western United States, riparian zones are shifting from native woody and herbaceous species to invasive grass …

Himalayan Blackberry (Rubus armeniacus) Effects on Fish Habitat: Impacts from Riparian Zones Inundated with Himalayan Blackberry
… lotic reaches (channel width 1.5-5 m) having riparian zones inundated with invasive Himalayan blackberry (Rubus armeniacus) plants (test conditions) (3 sites) and reaches with a riparian zone consisting primarily of native vegetation (reference conditions) (5 sites). This thesis studied …

A multi-scale, hierarchical approach to map the location and condition of riparian zones in the southern Rockies ecoregion
Riparian zones are important for their contribution to biodiversity and ecosystem services, especially in the western United States where riparian zones occupy a small proportion of the landscape but support a majority of the biodiversity. Riparian zones are currently threatened by multiple …

Monitoring the influx of marine derived Nitrogen and characterizing soil food webs of riparian zones of the Elwha River Watershed, WA, USA.
… Two sources of nitrogen to Pacific Northwest riparian areas are marine derived nitrogen (MDN) via anadromous pacific salmon and symbiotic nitrogen fixation via Alnus rubra. The recent removal of two large dams on the Elwha River, WA, opened up ~60 km of previously inaccessible river habitat …

The restoration of riparian plant communities following alien plant clearing in the Western Cape
Few of the riparian zones of the Western Cape Province, South Africa, can still be described as 'natural', as many, if not all, have been impacted upon in one way or another. They are, therefore, frequently disturbed environments that are highly susceptible to invasion by alien plants. the …

Beaver moderated fire resistance in the North Cascades and potential for climate change adaptation
… for harmful channel incision, which impairs riparian ecosystem function by lowering the water table, disconnecting floodplains from aquatic environments. However, wetlands and functioning riparian zones can reduce burn intensity. Beaver, with their unique ability to build dams, can restore …

An analysis of the spatial and temporal changes in the Riparian zone of the Berg River in the vicinity of Hermon: implications for governance
Riparian zones broadly refer to the interface between terrestrial and aquatic systems. It is widely acknowledged that riparian zones provide a number of services including that of an ecological corridor for migration of animal species; a habitat; food for aquatic macro invertebrates in the form of …

Investigation of hydrologic and sediment transport processes on riparian hillslopes
Riparian zones are increasingly being adopted as best management practices (BMPs) to control nonpoint source pollution. The effectiveness of these zones in mitigating pollution is a function of the distribution, nature, and rate of water and sediment movement through these zones. The intent of this …

Examination of small mammal diversity in the riparian areas of Walden, Tennessee
… B. Examination of Small Mammal Diversity in the Riparian Areas of Walden, Tennessee Thesis under the direction of Robert D. Keller, Ph.D., Assistant Professor of Biology It has been hypothesized that riparian zones are prime conservation habitats and can be used as indicators of general ecosystem …

Forest songbird abundance and viability at multiple scales on the Monongahela National Forest, West Virginia
… abundance and species richness in upland versus riparian zones. Riparian zones were areas within 50 m of first- and second-order mountain streams. Overall, more birds were found on upland than on riparian sites; this was true at landscape, transect, and point scales. Abundance of Acadian …

An investigation of riparian vegetation recovery following invasive alien tree clearing in the Western Cape
Riparian zones are dynamic, as a result of varying levels of disturbance from natural flooding regimes, and this makes them particularly susceptible habitats to invasion by alien plants. In South Africa, particularly the Fynbos Biome, closed-stand invasions by alien Acacia and Eucalyptus species …

Evaluation of Urban Riparian Buffers on Stream Health in the Tookany Watershed, PA
Stream channels and their corresponding riparian zones are composed of complex spatially and temporally dynamic systems. Changing land-use associated with urbanization has resulted in large shifts in riparian assemblages, stream hydraulics, and sediment dynamics leading to the degradation of the …

The effects of cattle exclusion on stream structure and function
… can be influenced by cattle grazing in the riparian zone due to sediment input, nutrient loading, and soil compaction, which lead to alterations of macroinvertebrate and microbial activity. Recently government programs, such as the Conservation Reserve Enhancement Program (CREP), have …
