Abstract:
Riparian areas in the Canadian boreal forest represent the transition zone between terrestrial and aquatic ecosystems. We review factors that influence riparian vegetation communities and the associated interactions with boreal streams. Regional and local drivers (e.g., climate, edaphic factors, and natural disturbances) that affect upland boreal vegetation also operate in riparian areas. However, the proximity of riparian areas to the stream channel not only modifies some of these drivers, but it means that the stream itself becomes a driver of riparian vegetation dynamics. For example, hydrological disturbances like flooding and ice scour affect soil texture and alter successional pathways, sometimes completely denuding streambanks of vegetation. Even in riparian areas unaffected by such catastrophic disturbances, saturated soil conditions can influence riparian forest composition and nutrient cycling. Saturated soils support lower mineralization rates, therefore organic layers store relatively more carbon and nitrogen than adjoining upland soils, and primary productivity is generally lower. Saturated soils also have implications for the ability of the riparian area to “buffer” streams from inputs of water and nutrients. For example, reducing conditions in riparian soils could be the sites for nitrate removal from groundwater by denitrification. Spatial variation in weather, soils, vegetation cover, slope, accumulation of organic matter, geographic location, and relief undoubtedly add to the complexity of understanding the role of riparian systems in Canada’s vast boreal forest. However, the opportunity to identify patterns relating to riparian areas will assist in our understanding and management of these multifaceted systems.

Abstract. Groundwater flowing from hillslopes through riparian (near stream) soils often undergoes chemical transformations that can substantially influence stream water chemistry. We used landscape analysis to predict total organic carbon (TOC) concentrations profiles and groundwater levels measured in the riparian zone (RZ) of a 67 km2 catchment in Sweden. TOC exported from 13 riparian soil profiles was then estimated based on the riparian flow-concentration integration model (RIM). Much of the observed spatial variability of riparian TOC concentrations in this system could be predicted from groundwater levels and the topographic wetness index (TWI). Organic riparian peat soils in forested areas emerged as hotspots exporting large amounts of TOC. Exports were subject to considerable temporal variations caused by a combination of variable flow conditions and changing soil water TOC concentrations. From more mineral riparian gley soils, on the other hand, only small amounts with relatively time-invariant concentrations were exported. Organic and mineral soils in RZs constitute a heterogeneous landscape mosaic that controls much of the spatial variability of stream water TOC. We developed an empirical regression-model based on the TWI to move beyond the plot scale to predict spatially variable riparian TOC concentration profiles for RZs underlain by glacial till.

Abstract:
Upland and riparian soils usually differ in soil texture and moisture conditions, thus, likely varying in carbon storage and turnover time. However, few studies have differentiated their functions on the storage of soil organic carbon (SOC) in sub-tropical broad-leaved evergreen forests. In this study, we aim to uncover the SOC storage and 14C apparent age, in the upland and riparian soils of a primary evergreen broad-leaved montane subtropical moist forest in the Ailao Mountains of southwestern China. We sampled the upland and riparian soils along four soil profiles down to the parent material at regular intervals from two local representative watersheds, and determined SOC concentrations, δ13C values and 14C apparent ages. We found that SOC concentration decreased exponentially and 14C apparent age increased linearly with soil depth in the four soil profiles. Although, soil depth was deeper in the upland soil profiles than the riparian soil profiles, the weighted mean SOC concentration was significantly greater in the riparian soil (25.7 ± 3.9 g/kg) than the upland soil (19.7 ± 2.3 g/kg), but has an equal total SOC content per unit of ground area around 21 kg/m2 in the two different type soils. SOC δ13C values varied between −23.7 (±0.8)‰ and −33.2 (±0.2)‰ in the two upland soil profiles and between −25.5 (±0.4)‰ and −36.8 (±0.4)‰ along the two riparian soil profiles, with greater variation in the riparian soil profiles than the upland soil profiles. The slope of increase in SOC 14C apparent age along soil depth in the riparian soil profiles was greater than in the upland soil profiles. The oldest apparent age of SOC 14C was 23,260 (±230) years BP (before present, i.e., 1950) in the riparian soil profiles and 19,045 (±150) years BP in the upland soil profiles. Our data suggest that the decomposition of SOC is slower in the riparian soil than in the upland soil, and the increased SOC loss in the upland soil from deforestation may partially be compensated by the deposition of the eroded upland SOC in the riparian area, as an under-appreciated carbon sink.

Abstract:
Abstract. Boreal headwaters are often lined by strips of highly organic soils, which are the last terrestrial environment to leave an imprint on discharging groundwater before it enters a stream. Because these riparian soils are so different from the Podzol soils that dominate much of the boreal landscape, they are known to have a major impact on the biogeochemistry of important elements such as C, N, P and Fe and the transfer of these elements from terrestrial to aquatic ecosystems. For most elements, however, the role of the riparian zone has remained unclear, although it should be expected that the mobility of many elements is affected by changes in, for example, pH, redox potential and concentration of organic carbon as they are transported through the riparian zone. Therefore, soil water and groundwater was sampled at different depths along a 22 m hillslope transect in the Krycklan catchment in northern Sweden using soil lysimeters and analysed for a large number of major and trace elements (Al, As, B, Ba, Ca, Cd, Cl, Co, Cr, Cs, Cu, Fe, K, La, Li, Mg, Mn, Na, Ni, Pb, Rb, Se, Si, Sr, Th, Ti, U, V, Zn, Zr) and other parameters such as sulfate and total organic carbon (TOC). The results showed that the concentrations of most investigated elements increased substantially (up to 60 times) as the water flowed from the uphill mineral soils and into the riparian zone, largely as a result of higher TOC concentrations. The stream water concentrations of these elements were typically somewhat lower than in the riparian zone, but still considerably higher than in the uphill mineral soils, which suggests that riparian soils have a decisive impact on the water quality of boreal streams. The degree of enrichment in the riparian zone for different elements could be linked to the affinity for organic matter, indicating that the pattern with strongly elevated concentrations in riparian soils is typical for organophilic substances. One likely explanation is that the solubility of many organophilic elements increases as a result of the higher concentrations of TOC in the riparian zone. Elements with low or modest affinity for organic matter (e.g. Na, Cl, K, Mg and Ca) occurred in similar or lower concentrations in the riparian zone. Despite the elevated concentrations of many elements in riparian soil water and groundwater, no increase in the concentrations in biota could be observed (bilberry leaves and spruce shoots).

Abstract:
Riparian soils and vegetation are important factors influencing the biodiversity and biogeochemical processes of river ecosystems. Riparian soils and vegetation form the foundation for multiple ecosystem services provided by river ecosystems. However, it remains poorly understood how riparian soils and vegetation interact with one another to maintain these services. In this study, we sampled four common types of riparian vegetation associated with the Beijiang River in South China. These included forestland, bamboo forest, mixed forest, and grassland ecosystems. Specifically, we analyzed the spatial distribution of riparian soils and their response to environmental factors (i.e., coverage and height of trees, shrubs and grass, distance to river, and altitude). Our results indicate that soil properties in riparian zones were affected significantly by vegetation type. In particular, clay content, soil organic carbon, and nitrate nitrogen content were significantly correlated with vegetation type. In contrast, changes in soil total nitrogen, total phosphorus, and available phosphorus content were not associated with vegetation type. Moreover, soil physical and chemical properties interacted with one an other, as well as with vegetation characteristics. This was indicated by the significant correlation observed between soil organic carbon, total nitrogen, total phosphorus, and soil texture, with structural characteristics of the four vegetation types. We also found that height and cover of trees and shrubs were significantly correlated with soil chemical properties. However, the effects of topographic variables such as altitude and distance to river were not significant. Results from this study can thus provide a basis for the ecological restoration and land management of degraded iparian zones.

Abstract:
Abstract. Denitrification within riparian buffers may trade reduced nonpoint source pollution of surface waters for increased greenhouse gas emissions resulting from denitrification-produced nitrous oxide (N2O). However, little is known about the N2O emission within conservation buffers established for water quality improvement or of the importance of short-term N2O peak emission following rewetting dry soils and thawing frozen soils. Such estimates are important in reducing uncertainties in current Intergovernmental Panel on Climate Change (IPCC) methodologies estimating soil N2O emission which are based on N inputs. This study contrasts N2O emission from riparian buffer systems of three perennial vegetation types and an adjacent crop field, and compares measured N2O emission with estimates based on the IPCC methodology. We measured soil properties, N inputs, weather conditions and N2O fluxes from soils in forested riparian buffers, warm-season and cool-season grass filters, and a crop field located in the Bear Creek watershed in central Iowa, USA. Cumulative N2O emissions from soils in all riparian buffers (5.8 kg N2O-N ha−1 in 2006–2007) were significantly less than those from crop field soils (24.0 kg N2O-N ha−1 in 2006–2007), with no difference among the buffer vegetation types. While N2O peak emissions (up to 70-fold increase) following the rewetting of dry soils and thawing of frozen soils comprised 46–70% of the annual N2O emissions from soils in the crop field, soils in the riparian buffers were less sensitive to such events (3 to 10-fold increase). The ratio of N2O emission to N inputs within riparian buffers (0.02) was smaller than those of crop field (0.07). These results indicate that N2O emission from soils within the riparian buffers established for water quality improvement should not be considered a major source of N2O emission compared to crop field emission. The observed large difference between measured N2O emissions and those estimated using the IPCC's recommended methodology (i.e., 87% underestimation) in the crop field suggests that the IPCC methodology may underestimate N2O emission in the regions where soil rewetting and thawing are common, and that conditions predicted by future climate-change scenarios may increase N2O emissions.

Abstract:
Soil hardness plays a vital role in evaluating the physical properties of soil structure. With regards to the impact of compaction on practical forest management issues, most report and review forms were available. Thus, the aim of this study was to evaluate the soil condition in riparian forest restoration planted with indigenous species along Kayan Ulu River with special reference to soil hardness. Soil hardness was measured by using Hasegawa-type cone penetrometer from the surface soils to 100 cm depth, with a total of 48 random points for both study sites surveyed; restoration sites planted with Shorea macrophylla in year 1996 and 1998 (SPD96 and SPD98, respectively) for both on and between planting lines. Our findings indicated that, soil hardness in SPD98 was harder as compared to SPD96 at shallow depth presented in one drop penetrability. Likewise, soil penetration resistance on planting line in SPD98 was significantly higher than SPD96 at surface soils (0-20 cm) and subsurface soils (20-40 cm). A high number of strikes and soil penetration resistance indicate that the soils were highly compacted. However, there was no significant difference in term of soil penetration resistance between planting line. In order to avoid effects on tree productivity, it is recommended that in future, the evaluation of soil hardness should be determined during the early establishment for future restoration of riparian ecosystem.

Abstract:
Riparian forests were frequently cleared and converted to agricultural pastures, but in recent times these pastures are often revegetated in an effort to return riparian forest structure and function. We tested if there is a change in the soil bacterial taxonomy and function in areas of riparian forest cleared for agricultural pasture then revegetated, and if soil bacterial taxonomy and function is related to vegetation and soil physicochemical properties. The study was conducted in six riparian areas in south-eastern Australia, each comprising of three land-use types: remnant riparian forest, cleared forest converted to pasture, and revegetated pastures. We surveyed three strata of vegetation and sampled surface soil and subsoil to characterize physicochemical properties. Taxonomic and functional composition of soil bacterial communities were assessed using 16S rRNA gene sequences and community level physiological profiles, respectively. Few soil physiochemical properties differed with land use despite distinct vegetation in pasture relative to remnant and revegetated areas. Overall bacterial taxonomic and functional composition of remnant forest and revegetated soils were distinct from pasture soil. Land-use differences were not consistent for all bacterial phyla, as Acidobacteria were more abundant in remnant soils; conversely, Actinobacteria were more abundant in pasture soils. Overall, bacterial metabolic activity and soil carbon and nitrogen content decreased with soil depth, while bacterial metabolic diversity and evenness increased with soil depth. Soil bacterial taxonomic composition was related to soil texture and soil fertility, but functional composition was only related to soil texture. Our results suggest that the conversion of riparian forests to pasture is associated with significant changes in the soil bacterial community, and that revegetation contributes to reversing such changes. Nevertheless, the observed changes in bacterial community composition (taxonomic and functional) were not directly related to changes in vegetation but were more closely related to soil attributes.

Abstract:
Abstract. The Three Gorges Reservoir encompasses a riparian zone with a vertical height of 30 m and a total area of 349 km2 that has been subjected to alternate inundation and exposure due to regular impoundment. Sedimentation on the riparian landforms constitutes an important pathway for riverine contaminant redistribution. In an attempt to understand heavy metal enrichment since water inundation, riparian sediments and soils were sampled along five transects in a typical riparian zone composed of cultivated bench terraces in the middle reaches. Heavy metals (Cr, Ni, Cu, Zn, As, Cd and Pb) were determined to characterize the lateral distribution and vertical transfer ratio. The results indicated that all heavy metals were enriched to varying extents both in the riparian sediments and soils, compared with regional background contents in soils and the reference levels in sediments. However, heavy metal levels in the riparian sediments were generally higher than those in the riparian soils, while those in the upper riparian soils (0–5 cm) were overall slightly higher than those in the lower riparian soils (5–10 cm). There was a decreasing trend of heavy metal contents with increasing elevation. The elevated levels of heavy metals in the riparian sediments may be attributed to sediment yields from upstream anthropogenic sources, especially during major rainstorms in the wet season when large loads of contaminated sediment may be produced from diffuse source areas. Heavy metals can also be adsorbed to pure sediment in the course of mobilization or after deposition. Considering that the riparian soils are local weathering products without mobilization, the enrichment of heavy metals may principally be ascribed to chemical adsorption from dissolved fractions or vertical transfer from overlaid sediments. Heavy metal enrichment may further be affected by the specific type of hydrologic regime such that relatively long flooding duration caused by water impoundment and natural floods was responsible for the relatively higher levels of heavy metals in the lower portions of the riparian zone.

Abstract:
The aim of the research was to evaluate the processes that determine P stability in riparian floodplain soils, with emphasis on chemical transformations in flood-drained calcareous soil. Flooding of soil columns showed an increase in P solubility (from 0.01 to 1.2 μg ml-1) largely due to the reductive dissolution of Fe minerals (solution Fe increased from < 0.05 to > 50 μg ml-1) and increased solubility of Ca-P minerals (solution Ca increased from < 100 to > 1000 μg ml-1). The periodic drainage of the flooded soil exported the equivalent of approximately O.l5 kg ha-1 (over six flood-drain cycles). Exported P correlated with soil solution P immediately before drainage (r2 = 0.99; P < 0.001). After drainage, there was a reversal of the reactions described above, with solution Fe, Ca and P returning to preflooding levels. Over the course of the 6 flood-drain cycles inorganic P became more stable, with Ca-P and Fe-P pools increasing (from 9 and 11 % respectively both to 14 % of TP) at the expense of labile pools. Similar patterns of P release and retention were observed during batch incubation studies of aerobic - anaerobic cycles using moist soil samples. Solution P and Fe were strongly correlated in both non-calcareous (r2 = 0.96) and calcareous (r2 = 0.73) soils. The role of Ca-P mineral solubility was disguised by the dissolution of calcium carbonate. Drying of the soil can lead to P release on re-wetting (up to eight-fold). This is most likely due to a release of P from ruptured microbial cells and transformations of Fe mineral surfaces. Monitoring suggested that all of these processes were active in the field, as the water table advanced and receded, though more slowly than in the laboratory. Over a four month flood-drain cycle losses of dissolved P from the floodplain were estimated at 0.034 kg ha-1. It is unlikely that this is significant relative to upstream inputs of P to the river from point sources and other types of agricultural land in the River Thames catchment.

Abstract:
The area between a stream and land is known as a riparian zone. These zones are highly dynamic whichcarry and accumulate heavy metals and environmental contaminants. Discrete Riparian Input Zones(DRIPs) are a subset of such zones that carry concentrated amounts of water into streams at discrete points.These are more active in their ability to channel water than riparian zones. These areas are important sincethey may retain or release metals and thereby affect the stream chemistry. To test if DRIPs accumulatemetals, 7 DRIPs and 4 Non-DRIPs were sampled along the C5 stream in the Krycklan Catchment. Soilsamples were taken from the surface down to 0.5 m depth at 0.1 m increments and were analysed for totalmercury, metals and loss on ignition. Three metals (vanadin, iron and zinc) were identified as having significant differences in concentration between DRIP and Non-DRIPS. Vanadin and Fe had significantlyhigher concentrations in Non-DRIPs, whereas iron had higher concentrations in DRIPs. Mercury,cadmium, iron, and loss on ignition (LOI) were found to decrease as depth increased, whilst Al was foundto increase with depth. Finally many elements are inter-related, but those with the strongest correlation areLOI and mercury, and iron and cadmium, both r > 0.85. LOI and mercury are strongly related as mercurybinds strongly to organic matter. The relationship of Fe and Cd is likely due to the Fe-oxide and Cdrelationship.

Full text
Abstract:
Riparian buffers have been proven to reduce nutrient and sediment transport to streams in agricultural watersheds. Southern Illinois offers a unique opportunity to study functions of riparian buffers in reclaimed mine soils. In Perry County, Illinois three stream segments of Bonnie Creek, Galum Creek and Pipestone Creek were restored to their approximate original position following mining. Between 1980 and 2000, as part of the restoration, vegetative buffers of grasses and trees were planted along the streams to minimize nutrient and sediment inputs from adjacent restored agricultural land. Our research objective was to determine whether riparian soil function was being restored in the vegetated buffers by comparing multiple soil properties to the adjacent reclaimed soils in agricultural production. Four transects were established on each study site through the buffer and agricultural field. Ten one meter plots were evenly spaced along each transect in each of the land uses. In summers 2010 and 2011, water infiltration rates, bulk density, total carbon concentration, total nitrogen concentration, and C:N ratio measurements were made to assess the restoration of soil function. Soil water infiltration was significantly higher and bulk density was significantly lower in the riparian buffers compared to the adjacent agricultural fields. In the riparian buffer, roots likely helped to break up the soil adding pore space, which reduced the bulk density and increased the water infiltration rates. Soil total carbon, total nitrogen, and C:N ratio were significantly higher in the riparian buffers than the agricultural fields. The additional organic matter inputs from the roots of the riparian vegetation along with incorporation of litter from the soil macrofauna likely helped to increase the soil carbon and nitrogen levels compared to the agricultural fields. Even though the soil C:N ratio was significantly higher in the riparian buffers than the agricultural fields, more time is needed to restore the ratio to levels where nitrogen will be immobilized not mineralized in the riparian soils. Soil function in the riparian areas should continue to develop at a faster rate compared to the agricultural fields due to the impact of the perennial vegetation. Restoration of landscapes is not estimated by the return of structure alone, it also includes the re-establishment of function such as soil quality improvement, water quality improvement, and wildlife habitat restoration.

Abstract:
Land use practices over the last 200 years have dramatically altered the distribution and amount of riparian vegetation throughout many catchments in Australia. This has lead to a number of negative impacts including a decrease in water quality, an increase in sediment transport and a decrease in the quality of terrestrial and aquatic habitats. The task of restoring the functions of riparian zones is an enormous one and requires spatial and temporal prioritisation. An analysis of the existing and historical functions of riparian zones and their spatial distribution is a major aid to this process and will enable efficient use of remediation resources. The approach developed in this thesis combines remote sensing, field measurement and terrain analysis to describe the distribution of five riparian zone functions: sediment trapping, bank stabilization, denitrification, stream shading and large woody debris production throughout a large semi-arid catchment in central Queensland.

Abstract:
Running waters reflect the character of their landscape. Landscapes influence their streams by supplying dissolved ions to the water, determining the organic matter supply to stream foodwebs, and influencing water temperature and water flows (Gregory et al. 1991, Hynes 1975). The water that feeds streams has passed over and through the vegetation, soils, and rocks of the valley. Just as urine carries the chemical imprint of metabolic activities (such as diabetes), the kinds and amounts of dissolved matter delivered to stream channels carry the signature of the valley’s parent materials and biota. Riparian (streamside) vegetation similarly regulates the balance of carbon sources to stream consumers. In valleys with sparse riparian vegetation, abundant light at the streambed allows in-stream primary production by protists and plants to dominate. Where riparian vegetation forms a canopy over the stream, leaves and needles from shrubs and trees dominate carbon supplies to consumers because low light limits contributions from in-stream primary producers (Vannote et al. 1980). Water temperature and flow are complexly determined by climatic controls (e.g., air and soil temperatures, patterns of precipitation), landscape physiography (e.g., shading of streams by valley walls), and the filter of lightabsorbing and water-transpiring riparian vegetation. Thus, streams in the desert biome of the American Southwest, with intermittent droughts and floods, high water temperatures, and abundant light, are very different habitats from the cool, dark waters of perennial streams in the temperate rain forest of the Pacific Northwest coast (Fisher 1995). Likewise, streams in the boreal forest of Alaska (and in the cold circumboreal forests of the world) take their cues from the landscape. Cold permeates the ecology of the boreal landscape and the running waters therein. The consequences of high-latitude climate on running waters are at least three: creation of ice in both terrestrial and running water systems; limited inputs of organic matter and nutrients to foodwebs; and thermal effects of low water temperatures on biological processes (Oswood 1997). For forested streams, a good case can be made for autumn as the beginning of the stream’s “fiscal” year. Autumnal leaf fall from riparian vegetation provides a major proportion of the annual energy budget to stream foodwebs.

Abstract:
<em>Abstract.</em>—Anadromous fishes such as salmonids link marine and terrestrial ecosystems in coastal watersheds of western North America. We examine here the extent of isotopic enrichment of salmon-derived nutrients in soil, vegetation, and terrestrial insects among six watersheds from coastal British Columbia that differ in the density of salmon. Results demonstrate a direct relationship between the salmon spawning density and 15N enrichment in humus soil, in riparian vegetation (<em>Tsuga heterophylla, Vaccinium parvifolium, Rubus spectabilis</em>), and in riparian insects including herbivorous and carnivorous Carabidae (<em>Pterostichus</em>, <em>Scaphinotus, Zacotus</em>). The results suggest broad cycling of salmon-derived nutrients into multiple trophic levels of terrestrial ecosystems. We also describe for the first time the detection of salmon-derived nitrogen in wood samples extracted from oldgrowth riparian conifers. This result suggests new opportunities for assessing relative nutrient transfer and salmon abundance in past centuries.

Abstract:
This chapter considers the subtler role of Prosopis in underpinning a fragile desert ecology. It is perhaps difficult to exaggerate the dominance of this genus within its desert environments, especially on the coast of Peru, where rather few tree species occur naturally. It is shown that no other desert tree has as pervasive an influence upon the soil's physical, chemical, biological, and moisture properties; the sub-canopy microclimate; the neighbouring vegetation; and the wildlife and insect populations. The huarango integrates diverse parts of the desert ecosystem. In modifying the environmental extremes characteristic of deserts, especially one as arid as the Peruvian south coast, Prosopis makes what would otherwise be inhospitable lands habitable for other species, including humankind. In other words, if we are to lay bare the ecological consequences of deforestation on the south coast, we need to understand why, here, the huarango is what ecologists term a ‘keystone species’.

Abstract:
Following stream impoundment, rivers respond via changes in sediment dynamics, channel morphology, and vegetation distribution. Such changes have occurred along the Provo River, Utah, located within the Intermountain West of the U.S. Jordanelle Dam was built on the Provo River in 1992 after the majority of dam construction in the United States and therefore allows for a large-scale GIS analysis using aerial photographs, available before and after construction. To evaluate the effects of the dam, this study examines reach scale channel changes with respect to vegetation distribution and species richness. Post-impoundment, the authors find that channels downstream of the dam have become more stable, allowing for vegetation colonization, as exhibited in land cover changes from bare soil to grass. This results in greater species richness owing to colonization of a more stable riparian zone, ultimately changing habitat conditions. Identifying and understanding the impacts of the Jordanelle Dam on vegetation is necessary for protection of this valued ecosystem as rapid development continues.
