	Riparian strips -- Facts, Info, and Encyclopedia article (Site not responding. Last check: 2007-10-29)
		Riparian strips consist of growth left in or near water courses particularly in (additional info and facts about clearfelling) clearfelling logging operations.
		The theory is that the growth will lessen the ((geology) the mechanical process of wearing or grinding something down (as by particles washing over it)) erosion prospects of the denuded land.
		Experience has shown that the strips were often far too small to achieve the stated purpose.

	Riparian - Wikipedia, the free encyclopedia
		Riparian areas or zones are the interface between land and water, and the adjacent land if frequently inundated with water.
		Riparian zones are an important matter in civil engineering due to their significance for managing erosion control, their ecologies and the large effect they have on aquatic ecosystems.
		Research has shown that riparian ecosystems are vital to the health of all other aquatic ecosystems as they filter out pollutants from land runoff, prevent erosion, and provide shelter and food for many aquatic animals.

	Understanding the Science Behind Riparian Forest Buffers: Effects on Water Quality
		Riparian area hydrology is influenced by local geology, topography, soils, and characteristics of the surrounding watershed.
		Riparian forests will have the most influence on water quality where subsurface runoff follows direct, shallow flow paths from the uplands to the stream, causing most of the drainage to pass through the riparian area before exiting into the stream.
		Riparian areas are also cleared to increase drainage, reduce competition with crops for moisture and sunlight, remove sources of noxious weeds, allow easier operation of farm machinery, and remove habitat for wildlife that may damage crops (Osborne and Kovacic 1993).

	Design of Forest Riparian Buffer Strips (Part 3)
		The riparian zone lies between the aquatic and upland zone and is an area of transitional vegetation influenced by its nearness to water.
		Upland areas adjoin the riparian zone and are usually characterized by vegetation and soils different from those in the riparian zone.
		In Idaho, buffer strip width is determined primarily by stream class on the basis of beneficial uses without consideration of site-specific factors, except in the special cases of stream segments of concern.

	Design of Forest Riparian Buffer Strips (Part 5)
		Although the effectiveness of buffer strips as filters was not evaluated, Skille noted that early fall burning tended to reduce increases in stream concentrations of N and P because early rainfall was adequate to move the nutrients into the soil, but inadequate to carry them to the stream.
		The utility of forest riparian zones as buffers for sediment and nutrients from agricultural lands is of interest because forested riparian lands are commonly used for containment of wastes.
		Buffer strip impacts on the aquatic food chain are documented reasonably well by studies contrasting the effects of timber harvests with and without buffer strips.

	Design of Forest Riparian Buffer Strips (Part 6)
		But because actual buffer strip widths were not reported and widths greater than the minimum may be used, it is not logical to infer from the audits that the minimum widths were adequate.
		Then the buffer strip width required for LOD recruitment, based on the proximity of a tree to the stream and the conditional probability it will fall into the stream, is found to be 85 feet.
		The protective strip width was related to road drainage factors, including cross-ditch interval, road gradient, fill slope length, and the number and types of flow obstructions along the slope.

	Restoration of Chico's Riparian Habitats
		Due to the number of diverse groups involved locally in riparian restoration projects, it would be useful for the city to have a concept paper including specifically defined parameters and assurances of quality control to guide the efforts of volunteers or organizations with grant funds working within the city.
		The associated riparian strips provide habitat for a variety of wintering and resident songbirds as well as resident species of amphibians, reptiles, and mammals.
		In the heart of the riparian zone, where the potential of falling limbs poses no danger, exotic trees up to a foot in diameter will be girdled and left to die and become woodpecker habitat and a source of woody debris.

		Riparian afforestation reduced water yields by 68 to 104 mm (21-55%) when the Pinus radiata stand was 8 to 10 yr old.
		Language: English Descriptors: Iowa; Salicaceae; Populus; Sustainability; Strip cropping; Groundwater; Water quality; Nitrates; Nitrogen; Nutrient uptake; Ecosystems Abstract: Research at the University of Iowa is testing the ECOLOTREE BUFFER, a prototype wooded buffer strip planted between a creek and row-cropped land with roots grown intentionally deep enough to intersect the near-surface water table.
		The wooded riparian strip changes the local agroecosystem by reducing fertilizer nutrients causing surface water eutrophication, by diversifying wildlife habitat, by reducing soils erosion caused by wind and water, by diversifying the crop base, by creating an aesthetic addition in the landscape.

	Costs of Producing Biomass from Riparian Buffer Strips (Site not responding. Last check: 2007-10-29)
		One potential means of ameliorating this problem is the use of riparian buffer strips.
		Riparian buffer strips intercept overland flows of water, sediments, nutrients, and pollutants; and ground water flows of nutrients and pollutants.
		Costs are estimated for three biomass systems grown on buffer strips: willow planted at a density of 15,300 trees/ha (6200 trees/acre); poplar planted at a density of 1345 trees/ha (545 trees/acre); and switchgrass.

		We examined how atrazine was leached or degraded in soil from 5-year and 9-year old switchgrass buffer strips and compared atrazine behavior in RBS to that in adjacent cropped lands.
		Technical Abstract: Atrazine is a herbicide with extensive use in the corn-growing regions of the U.S. Riparian buffer strips (RBS) have potential for reducing atrazine transport from agricultural land to streams in runoff.
		We compared transport and fate of atrazine in soil columns from 3-yr, 5-yr and 9-yr old switchgrass (Panicum virgatum L.) buffer strips to atrazine behavior in adjacent lands cropped to corn or alfalfa pasture.
