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). …

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 …

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 replanting and restoration of riparian buffers on arthropods in oil palm systems
… and restore areas around rivers in plantations (“riparian buffers”) – can affect oil palm systems. This PhD was based primarily at the Biodiversity and Ecosystem Function in Tropical Agriculture (BEFTA) Programme in Sumatra, Indonesia, within oil palm plantations that received different levels of …

Potential Adoption of Native Fruit and Nut Tree Riparian Buffers on Private Land in Western Virginia
Riparian corridors are often farmed or grazed because they are typically productive and offer a low cost water supply for livestock. These areas are also critical in terms of water quality, soil retention, and aquatic and terrestrial wildlife habitat. Conservation of riparian areas can be …

Denitrification and organic carbon in a series of riparian buffers in the Bear Creek National Demonstration Watershed
<p>Riparian buffers have been shown to be effective at improving surface water quality. Vegetative uptake and denitrification are interrelated nitrogen removal services of riparian buffers. Surface denitrification rates are much higher than subsurface rates, however, subsurface denitrification is …

Quantification of the Effectiveness of Agricultural Riparian Buffers to Protect Stream Health in Maryland's Coastal Plain and Piedmont Regions
… quantified the effectiveness of agricultural riparian buffers to protect stream health in Maryland's Coastal Plain and Piedmont physiographic regions. Easily-obtainable data were used to develop scientific guidance for buffer management strategies. Three data sets were used: the 1998 …

NUTRIENT RETENTION BY RIPARIAN FORESTED BUFFERS IN WESTERN MARYLAND: DO THEY WORK AND ARE THEY WORTH IT?
Riparian buffers are a best management practice (BMP) implemented to improve water quality. In 1997, Maryland established the Conservation Reserve Enhancement Program (CREP) to give landowners incentives to install riparian buffers that would help restore the Chesapeake Bay. Although many studies …

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 …

Riparian Restoration, Success Criteria, and Application to the BART Sabrecat Creek Riparian Restoration Project in Fremont, California
<p>Riparian restoration is a complex, inter-disciplinary field that is open to interpretation by its practitioners. This research reviews some of the critical elements of riparian restoration, including the watershed, surrounding land use, adjacent habitat, and riparian buffers; special-status …

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 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 …

Effectiveness of naturally-occurring riparian forest buffers and grass filter strips at buffering concentrated flow from row crop fields to streams in northeast Missouri
… concentrated flow paths (CFPs) by natural forest buffers and grass filter strips was conducted at 11 farms in three northeast Missouri watersheds. Results from the survey examining 74 CFPs occurring in row crop fields found that natural forest buffers dispersed flow from 80% of CFPs before they …

Survival and space use of riparian muskrats (Ondatra zibethicus) within an agroecosystem
… have shifted much of their distribution to riparian habitats that have unstable flow regimes and inundation times that could be related to position within watersheds. Muskrats (Ondatra zibethicus) are an economically important furbearer species in this region and occur in small streams and …

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 …

Using GIS and Land Use Data to Select Candidate Reference Sites for Stream Bioassessment
… the entire catchment and for 10, 40, and 130-m riparian buffers, road and impoundment density and stream/road crossings. Sites were then ranked by land use impairment, with the least impaired selected as candidate reference sites. The larger buffers, impoundment density, and stream/road crossing …

Recovery of Channel Morphology and Benthic Macroinvertebrate Assemblages after Livestock Exclusion
… stream reaches result in improved geomorphic and riparian vegetation condition, but do not significantly improve the benthic macroinvertebrate assemblage. Detailed longitudinal and cross-sectional surveys, pebble counts, and rapid geomorphic assessments were conducted on contiguous, paired stream …

The Introduction of a Chip Mill: Effects on Deforestation Rates and Timber Harvest Locations in Southeast Missouri
… objective was to locate areas of steep slopes or riparian buffers that may be environmentally sensitive to timber harvesting activities and determine if there was an increase in timber harvesting activities in these locations after the introduction of the chip mill. This study found that there had …

Simulation and assessment of highly altered hydrologic system responses to anthropogenic and natural stressors at the watershed scale
… (Drake and Hogan, 2013). Examples of WMPs are riparian buffers, reduced tillage practice, filter strips, cover crops and crop rotation. Hence, WMPs may be viewed as anthropogenic stressors strategically implemented to reduce the impacts of farming activities on the ecosystem. The implementation …
