Effects of riparian buffer width on stream salamander populations in the southern Appalachian Mountains
… populations and to assess the efficacy of riparian buffers in ameliorating these effects. My data show that larval two-lined salamanders are negatively impacted by increased stream sedimentation following riparian logging and that increasing the riparian buffer around the stream reduces …

Evaluating Determinants of Participation in Voluntary Riparian Buffer Programs: A Case Study of Maryland's Buffer Incentive Program
Forest or grass buffers planted along streams or other waterbodies are receiving considerable attention by policy makers as a way of providing a range of environmental benefits for society, especially prevention of non-point source water pollution from agricultural land. The current emphasis of …

The Dogma of the 30 Meter Riparian Buffer: The Case of the Boreal Toad (Bufo boreas boreas)
<p>We tested the adequacy of standard 30 m riparian buffers for semi-aquatic vertebrate species, using the boreal toad (Bufo boreas boreas) as an example. We monitored toad populations in south-central Utah using radio telemetry during the summers of 2003 and 2004. We found 30 m buffers inadequate …

Nitrogen, phosphorus and potassium removal from perennial energy grasses when grown on wet marginal land
… on nutrient removal in grass biomass grown on a riparian buffer. Harvest year, harvest timing, species, and N- rate, all significantly affected nutrient concentrations in biomass and removals. Nutrient removal across all species was generally greater at H1 than with H2 and with increasing …

Hedonic Valuation of Forested Riparian Buffers Along Rivers in Northwestern North Carolina
… owning a home along a river and tree coverage of riparian areas along rivers. The setting of this study is Ashe and Watauga Counties in Northwestern North Carolina and the two rivers that flow through those counties: New River and Watauga River. House sales form the basis of the hedonic models …

Estimating minimum thresholds of natural vegetation for the integrated management and protection of water quality in South African catchments
… across the whole catchment and within a 200 m riparian buffer zone. At both scales, however, fragmentation was not found to be significant. The models further indicated that approximately 82 to 90% natural vegetation cover was necessary at these scales to keep pollution scores within acceptable …

Effect Of Stream Channel Incision On The Depth To Groundwater In Riparian Corridors Across Southwestern Minnesota
Riparian buffers have the potential to remove nitrogen from shallow groundwater in the riparian corridor. Streams with a higher degree of incision may be less likely to have elevated groundwater tables, making them less effective at removing nitrogen from groundwater. By determining if there is a …

THE INFLUENCE OF SEASON, FLOW REGIME, AND WATERSHED LAND USE AND LAND COVER ON NUTRIENT DELIVERY TO TWO RAPIDLY URBANIZING WATERSHEDS IN CENTRAL INDIANA, USA
… is developed. Results also indicate that riparian buffer downstream of intense agriculture lands dilutes high agricultural NO3-N concentrations, but not enough to return in-stream concentrations to natural levels.

Water Use and Water Tolerance in the Riparian Species American Sycamore (Plantanus occidentalis L.) and How its Physiology Compares to the Coexisting Black Willow (Salix nigra Marshall)
… and tolerance to inundation and drought of two riparian tree species, <em>Platanus occidentalis</em> L. and <em>Salix nigra</em> Marshall. The main goal of the study was to better understand the two species and assess the suitability of <em>P. occidentalis </em>for use in riparian restoration. …

Testing the efficacy of mitigation measures for reducing fine sediment and associated pollutant delivery to and through rivers in agricultural catchments of England
… to farm infrastructure, a wooded and a grassed riparian buffer, and a constructed wetland and in-stream pond treatment train. The improved farm infrastructure (resurfacing of a farm track, installation of a retention pond, improvements to a drainage ditch) effectively reduced inputs of sediment …

The Effects of Vegetation on Stream Bank Erosion
Riparian buffers are promoted for water quality improvement, habitat restoration, and stream bank stabilization. While considerable research has been conducted on the effects of riparian buffers on water quality and aquatic habitat, little is known about the influence of riparian vegetation on …

Effect of Urbanization on the Hyporheic Zone: Lessons from the Virginia Piedmont
… increased and sinuosity decreased as the riparian buffer width increased; these trends are weak and are essentially negligible. The hydraulic conductivity results conform to expected trends and are a product of aforementioned concomitant processes. Our results emphasize the complexity of …

Developing a rapid method for assessing the physical stability of streams in Minnesota's Agassiz beach ridges
… The indicators are: (1) instream habitat, (2) riparian buffer, (3) access to floodplain, (4) sinuosity, (5) degree of incision, (6) bank stability, and (7) incipient particle diameter and channel material. The method is generally applicable to wadeable streams throughout the Minnesota glacial …

Perennial energy crops on riparian buffers affect nitrogen cycling microbial communities
… involved in the N cycle on a wet marginal riparian buffer. We investigated the abundances of genes encoding the enzymes of N cycling functional groups involved in ammonia oxidation (amoA), nitrite ammonification (nrfA), denitrification (nirK, nirS, norB, and nosZ), and N fixation (nifH). …

The role of forest stream corridor characteristics in influencing stream and riparian ecology
… design in relation to both in-stream and riparian zone biodiversity and functioning. The contribution, availability and source of basal resources within varying corridor conditions are the focus of this project. This approach is combined with surveys of community diversity on a number of …

Abundance, Distribution, and Geometry of Naturally Occurring Macropores in Stream Banks
… of water and solutes between the channel and riparian groundwater, yet the geographic distribution of bank macropores is unknown. Here we determined the abundance, distribution, and geometry of naturally occurring surface-connected macropores in the banks of 20 streams across five …

BMP Cost and Nutrient Management Effectiveness on Typical Beef and Beef-Poultry Farms in Shenandoah County, Virginia
… cropping, winter wheat cover crop, herbaceous riparian buffer, fencing, and P-based NMP were the BMPs that were analyzed. Incentive payments from state and federal governments were incorporated into the cost of BMP adoption. A brief analysis of a farmer's time value of money, with respect to …

Modelling steroidal hormone transport and evaluating best management practices in New Zealand dairy farming systems
… in ArcSWAT, including constructed wetlands, riparian buffer strips, grazing management, and effluent application timing management. All BMPs reduced estrogen and sediment delivery to some degree, but their performance varied. Constructed wetlands placed at critical drainage points showed the …
