Bethesda, Md. : Society of American Foresters; 1992 Feb. Southern journal of applied forestry v. 16 (1): p. 13-20; 1992 Feb. Includes references. Language: English Descriptors: Alabama; Florida; Georgia; Harvesting; Logging; Water quality; Protection; Resource conservation; Economic analysis; Costs Abstract: Data on harvest volumes, topography, and other site and area characteristics were obtained from 22 timber harvests in Alabama, Florida, and Georgia. An economic analysis was then used to estimate the marginal costs of implementing each state's recommended Best Management Practices (BMPs), as well as a set of enhanced BMPs an these sites. Considering all of the areas combined, the costs of using the recommended BMPs averaged 2.9% of gross timber sale revenue, $2.34 per thousand board feet (mbf) of timber harvested, or $12.45/ac. The cost of implementing the enhanced BMPs averaged 5.1% of gross stumpage value, $4.13/mbf, or $21.94/ac. Seed, fertilizer, and mulch, broad based dips, and water bars were the most expensive practices on a total cost basis. Culvert installation, streamside management zones, and road relocation costs were less expensive for most tracts. 12 NAL Call. No.: aSD11.F6 Cumulative effects on an ecosystem. Tippets, B.

Washington, D.C. : American Geophysical Union; 1990 Dec. Water resources research v. 26 (12): p. 2949-2957. ill., maps; 1990 Dec. Includes references. Language: English Descriptors: Ontario; Watersheds; Forests; Carbon cycle; Carbon; Isotope labeling; Catchment hydrology; Water quality Abstract: Dissolved organic carbon (DOC) is important in the acid-base chemistry of acid-sensitive freshwater systems; in the complexation, mobility, persistence, and toxicity of metals and other pollutants; and in lake carbon metabolism. Carbon isotopes (13C and 14C) are used to study the origin, transport, and fate of DOC in a softwater catchment in central Ontario. Precipitation, soil percolates, groundwaters, stream, beaver pond, and lake waters, and lake sediment pore water were characterized chemically and isotopically. In addition to total DOC, isotopic measurements were made on the humic and fulvic DOC fractions. The lake is a net sink for DOC. delta 14C results indicate that the turnover time of most of the DOC in streams, lakes, and wetlands is fast, less than 40 years, and on the same time scale as changes in acidic deposition. DOC in groundwaters is composed of older carbon than surface waters, indicating extensive cycling of DOC in the upper soil zone or aquifer. 14 NAL Call. No.: QH540.J6 Downstream effects of timber harvesting on channel morphology in Elk River Basin, Oregon. Ryan, S.E.; Grant, G.E. Madison, Wis. : American Society of Agronomy; 1991 Jan. Journal of environmental quality v. 20 (1): p. 60-72; 1991 Jan. Includes references. Language: English Descriptors: Oregon; Logging; Landslides; Floods; Sediment; Water erosion; Aerial photography; Canopy; Channels; Environmental impact; Riparian forests; Water quality; Water resources Abstract: Downstream effects, a type of cumulative watershed effect, were identified using changes in the width and distribution of open riparian canopies measured from aerial photography taken between 1956 and 1979 in Elk River basin, southwest Oregon. Open canopies appear on serial photographs of densely forested basins as unvegetated areas bordering stream channels. Opening occurs when large disturbances, such as landslides, debris flows, large floods, and excessive sedimentation, disrupt the vegetation in the riparian corridor. Downstream changes in channel morphology, inferred by the changing pattern of open reaches were linked to upslope forestry activities; a causal link was assumed where: (i) open reaches extended continuously downstream from clearcuts and roads or (ii) the timing and pattern of opening downstream varied in direct relation to the intensity of upslope forestry activities. Open riparian canopies were observed in first- through fifth-order channels, though only 11% of open reaches in low-order channels were spatially connected to open reaches in higher order channels. Open reaches on low-order tributaries were attributed to landslides and surface erosion generated from clearcuts and roads; the total length of open reaches in low-order channels increased 30-fold during the study period. Open reaches occurred on higher-order channels throughout the study period but did not increase in size or change location in relation to upslope harvest activities. Instead, open canopies were restricted mainly to wide and low gradient channel reaches, which comprised approximately one- third of the length of higher-order channels. Limited downstream change in riparian canopies associated with upslope forestry activity during the study period, which included a 100-yr storm, was attributed to three physical factors: (i) lack of debris flows in most parts of the basin; (ii) channels constrained by competent hillslopes limiting the potential for opening; and (iii) low harve 15 NAL Call.

Language: English Descriptors: Scotland; Aluminum; Iron; Carbon; Anions; Acid deposition; Liming; Afforestation; Coniferous forests; Streams; Watersheds; Moorland; Land use; Catchment hydrology; Chemical composition; Water quality Abstract: Concentrations of total, total monomeric and organic monomeric forms of aluminium and of iron, anions and dissolved organic carbon (DOC) in streams draining one forested and two moorland catchments in southwest Scotland were measured over a 3-year period. Catchments were limed during the study and comparisons of stream chemistry were made before and after liming under the two land-use types. Within individual events, DOC and anion concentrations increased with increasing discharge, and aluminium concentrations showed little change with discharge. In the pre-liming phase as a whole, organic monomeric Al was strongly correlated with DOC and inorganic monomeric Al was strongly correlated with anions, particularly Cl. The forested catchment had higher mean DOC and SO4, but lower mean Al. After liming, Al concentrations were reduced, by up to 80% for monomeric forms, and these low levels prevented observation of correlations with DOC and anions. Liming treatments were effective in both forested and moorland catchments, lasted for at least 2.5 years after treatment, and low rates of application to bog areas were as effective as entire catchment treatments. 18 NAL Call.

Language: English Descriptors: Western australia; Deforestation; Land clearance; Watersheds; Catchment hydrology; Groundwater level; Streams; Stream flow; Salinity; Water quality; Agricultural land; Land use; Agricultural development Abstract: A small (344ha) experimental catchment in southwest Western Australia was partially deforested (western 53% of the catchment) in 1976 to study the effects of agricultural development on water quantity and quality. The impact on the groundwater system in the cleared area was dramatic. Initial rates of rise were only 0.11 m year-1 but this increased after 10 years to average 2.3 m year-1. Groundwater rises of 15 m in the valley and 20-25 m on the lower sideslopes were observed over 13 years. A small seep (groundwater discharge area) appeared for the first time in 1988 and by 1989 it covered an area of 1 ha. Streamflow initially increased by 30 mm year-1 (4.0% rainfall) compared with a native forest average streamflow of 8 mm year-1 (1.0% rainfall). However, since the seep area developed, the increase in streamflow has been 50 mm year-1 (6.6% rainfall). Stream salinity was low prior to clearing (30 mgl-1 Cl-) and remained low for 9 years after clearing. However, since 1987. stream salinity increased dramatically as the ground water approached the ground surface, and by 1989 reached an annual average of 290 mgl-1 Cl-. The daily maximum in 1989 was 2200 mgl-1 Cl- compared with 92 mgl-1 Cl- from 1976 to 1986. The catchment changed from net salt accumulation pre-clearing to net salt export after 1987. Thirteen years after clearing, the groundwater level, stream yield, stream salt load and stream salinity had not reached equilibrium but were all still increasing. 23 NAL Call.

Language: English Descriptors: Wales; Coniferous forests; Clearcutting; Deforestation; Logging effects; Watersheds; Streams; Water quality; Acidification; Stream flow; Seasonal fluctuations; Groundwater; Soil chemistry; Losses from soil systems; Catchment hydrology Abstract: The effects of a 3 year conifer harvesting programme on stream-water quality are described for the acidic and acid-sensitive Afon Hore catchment. Nitrate and potassium concentrations, initially almost quadrupled, have remained high for 4 years from the commencement of the harvesting programme. For the undisturbed (control) system, the fluctuations are small and peak during the winter months. With harvesting, a phase change takes place and peak concentrations occur during the autumn period. A similar pattern, but with no phase shift, is observed for dissolved organic matter, although concentrations increase less: peak concentrations occur during the summer to autumn periods. During the first 2 years of felling, aluminium concentrations increase in the winter period: after that, concentration differences are much smaller. During the summer base-flow period, alkalinity and calcium values decrease. Sodium and chloride concentrations increase with time owing to a corresponding increase in the rainfall input. This trend is not observed for the stream in the felled catchment. For sulphate, there is a general decline in concentration for both the control and felled areas. With felling, a seasonal pattern has been introduced: the lowest concentrations occur in winter. The results are interpreted in terms of: (1) reduced atmospheric scavenging of sea salt and sulphur due to the loss of the trees; (2) increased losses of the nutrients from the soils due to reduced uptake by the vegetation; (3) increased aluminium releases from the soil's cation exchange store following increased total inorganic anion concentrations resulting from nitrate generation from (2); (4) a reduced contribution of ground water to the stream or an increased acidification of the ground water. The results are discussed in relation to environmental and water management issues. Nitrate production will probably not be of importance to either, owing to the low levels found in the stream.

Hornung, guest editors. Includes references. Language: English Descriptors: German federal republic; Watersheds; Forests; Throughfall; Rain; Streams; Nitrogen; Sulfur; Deposition; Acidification; Biogeochemistry; Physicochemical properties; Biological activity in soil; Mineralization; Forest soils; Mountain areas Abstract: Rainfall and throughfall inputs of all major cations and anions, via open-field bulk precipitation and canopy throughfall, are compared with streamwater outputs in two forested catchments at higher altitudes of the Black Forest. The sites differ considerably in terms of bedrock geology, soil type, soilwater characteristics, topography, and forest management history. Deposition at both sites is almost equal and, in contrast to other forest areas in Central Europe, of a low-to-moderate level. Dry deposition does not seem to play an important role. Distinct differences in the elemental output emerge owing to the differing site conditions. At Villingen, deposited nitrogen is almost totally retained, whereas at Schluchsee, nitrogen output and input are of the same order of magnitude. This is consistent with the different nitrogen nutrition level of the stands, microbial turnover in the soil, and former management practices (change of tree species, excessive nutrient export). Sulphur is not retained in either of the catchments. At Schluchsee, sulphur export exceeds input from canopy throughfall by a factor of 2.5. The higher output rates, both of nitrogen and sulphur at Schluchsee, are due to the much higher microbial mineralization of organic matter as shown by previous incubation tests. Differences in cation and proton export are mainly caused by a different drainage pattern. In contrast to the Schluchsee catchment, where vertical water pathways prevail, the streamwater solute output at Villingen is dominated by a shallow subsurface runoff. Atmospheric deposition is a contributing, but not the dominant, factor in the biogeochemical cycling at these sites. Hence, a generally applicable quantitative definition of 'critical loads', especially for nitrogen, is illusory and the use of such numbers will be misleading. 26 NAL Call.

Language: English Descriptors: Western australia; Water table; Salinity; Watersheds; Pastures; Land; Clearance; Afforestation; Land use; Agricultural development; Catchment hydrology; Water quality Abstract: Replacement of deep-rooted perennial vegetation with annual crops and pastures has led to rising groundwater tables and transport of previously stored salts to streams in south-west Western Australia. Trials to determine the potential of various reforestation strategies to reverse this process by lowering the groundwater table were commenced in 1976. Results are reported from six experimental sites for the period 1979-1986. Despite the mean annual rainfall of the experimental period being 10% below the 1926-1986 mean, groundwater levels under pasture rose by up to 1.2 m. The change in groundwater levels beneath reforestation ranged from a 0.6 m increase to a 3 m decrease relative to the ground surface. Groundwater levels under reforestation in all cases decreased relative to groundwater levels under pasture. The magnitude of this reduction was shown to increase with the proportion of cleared area reforested and with the crown cover of the reforestation. The salinity of the water table decreased by 12% under reforestation and by 32% under pasture over the period 1979-1986. 40 NAL Call.

Language: English Descriptors: France; Grasslands; Fagus; Picea; Watersheds; Acidification; Streams; Precipitation; Chemical composition; Water quality; Stream flow; Catchment hydrology Abstract: Eight years of hydrochemical data are presented for streams draining beech forest, grassland and spruce forest catchments in the Mont Lozere region. The mean concentration of cations in the streams occurs in the order: beech forest < grassland < spruce forest. The broad changes in stream chemistry follow a synchronous pattern related to variations in climatic conditions. Stream chemistry varies only to a moderate degree with flow, though in fine detail concentration fluctuations are very complex during storm events; hysteresis is observed. Estimations of pCO2 levels from the pH and alkalinity data show a wide scatter: the levels seem to be about five times the atmospheric value for all the streams. It is concluded that these catchments are still in an early stage of acidification. The spruce forest catchment acidifies faster than the woodland and the grassland catchments. Uncertainty remains as to the importance of air scavenging processes. 44 NAL Call. No.: 292.8 J82 Hydrogeochemical variations in Hafren Forest stream waters, Mid-Wales.

Language: English Descriptors: Wales; Stream flow; Drainage water; Watersheds; Picea sitchensis; Water quality; Acidification; Catchment hydrology; Temporal variation; Seasonality Abstract: Results are presented for a study attempting to assess the effects of conifer planting/harvesting and acidic oxide deposition on streamwater quality in a 25 to 45-year-old sitka spruce plantation on acid moorland. This is undertaken to demonstrate the application of a multi-element survey in providing 'chemical fingerprints' for describing hydrological and hydrochemical controls within catchments. Hafren forest streamwater chemistry varies for different components: nitrate, bromide, total iodine and total organic carbon show seasonal oscillations varying in phase and amplitude; aluminium and hydrogen ion concentrations vary as a function of flow; manganese and cobalt remain approximately constant except under very dry conditions when concentrations reduce by up to 10 fold. No direct link exists between rain and streamwater chemistry: streamwater chemistry variations are determined primarily by hydrological and chemical reactions in the surface organic-rich soils and the underlying inorganic soils/bedrock. Reactions in the organic-rich horizons involve the generation of acidic conditions and the mobilization/transport of transition metals that can be easily hydrolysed. Biologically mediated breakdown processes determine, in part, the hydrochemical behaviour of dissolved organic carbon, the nutrients, bromine and iodine. Reactions in the inorganic zones involve hydrogen ion consumption and the release of calcium and magnesium. Bicarbonate ions are generated by deprotonation of biogenically derived H2CO3 and the decomposition of calcium carbonate in the bedrock. The initial effects of forest clearfelling are demonstrated; increases in nitrate and potassium occur. A simple mixing model is presented to show that either a large proportion of the storm water is derived from 'non-hillslope', 'groundwater', sources, or major modifications occur as soil water passes rapidly to the stream; whichever process is operative, it has not been identified directly within the catchme 45 NAL Call.

Language: English Descriptors: Wales; Watersheds; Afforestation; Coniferous forests; Acidity; Runoff; Aluminum; Soil water; Stagnopodzols; Peat soils; Acid soils; Hydrological factors; Catchment hydrology; Overland flow; Storms; Drainage channels; Surface water; Seepage Abstract: Recent research has shown that storm runoff in afforested catchments at Llyn Brianne, Mid-Wales, is acidic and Al rich. However, relatively little is known about which hydrological pathways contribute to the generation of acid storm runoff. This paper reports the results of a year-long field investigation which examined the hydrological controls on stream water chemistry in a 1.5 ha subcatchment dominated by stagnopodzol and peat soils. During storm episodes, overland flow from the peat makes the dominant runoff contribution to the hydrological response of the subcatchment. This is strongly acidic (pH < 4.0) with a low Al content, though its interaction with the mineral lining of drainage channels results in the release of Al into surface waters. The stagnopodzols are characterized by vertical hydrological pathways; lateral flow occurs only above the bedrock, 1 m below the soil surface. In storm events, this flow path transfers acidic (pH 4.5), Al-rich soil water to streams. Drainage from the stagnopodzols also sustains base flows from the subcatchment. Almost 30% of effective precipitation is lost from the subcatchment as seepage, mainly through the drift material lining forest drainage channels. Seepage losses to deeper flow paths appear to be important in headwater catchments in upland Wales and warrant further study. 47 NAL Call.

Language: English Descriptors: New Hampshire; Stream flow; Drainage water; Subsurface layers; Forests; Watersheds; Catchment hydrology; Biogeochemistry; Spatial variation; Temporal variation; Acidification; Neutralization Abstract: Longitudinal variations of concentration-discharge relationships and chemical fluxes were evaluated in two headwater streams at the Hubbard Brook Experimental Forest, New Hampshire. At high elevations changes in subsurface flow paths explained variations in H+, inorganic Al and Si concentrations, whereas variations of DOC concentration were inconsistent with this mechanism. Flow responses of middle and low elevation subcatchments were influenced by variable contributions of hydrologic source areas and the elevational concentration gradient which exists in these catchments, but in most cases were not consistent with responses predicted by changes in flow paths. Spatial patterns of chemical fluxes indicate that, in general, catchment neutralization processes increased in effectiveness in the downslope direction. However, this pattern can be interrupted by secondary tributaries, both ephemeral and persistent, which originate in variable source areas that contribute acidic surface runoff during high flow conditions. Current models of catchment acidification need to incorporate spatial variations of biogeochemical processes and flow responses to improve predictions of short-term variations in surface water chemistry. 52 NAL Call.

Language: English Descriptors: West Virginia; Watersheds; Mountain forests; River water; Calcium ions; Electrical conductivity; Ion activity; Nitrate; Nitrification; Precipitation; Streams; Water quality; Forest soils; Leaching Abstract: The electrical conductivity of stream water draining from an unmanaged and undisturbed control watershed has been increasing rather steadily, about 0.03 mS m-1 yr-1, since 1971. During this period, NO3- and Ca2+ concentrations increased and were shown to mathematically account for the ionic contribution to conductivity; therefore, they are believed to be primarily responsible for the increase. However, the percentage of conductivity explained by the two ions was different over time. The percentage of conductivity attributable to NO3- increased in a pattern very similar to concentration. In contrast, the percentage of conductivity attributable to Ca2+ decreased slightly over time. The Ca2+ is believed to be pairing with the NO3- as the NO3- ions leach through the soil. While nitrification in mature stands can be strongly inhibited, limited nitrification, especially in forest gaps, and high anthropogenic inputs of NO3- probably were primary sources of the leached NO3-. Preferential adsorption of SO4(2-), rather than NO3-, on soil colloids is given as an explanation for the lack of retention of NO3- in the soil system and subsequent leaching to the stream. 54 NAL Call.

Language: English Descriptors: California; Oregon; Erosion; Forest influences; Forest management; Logging; Precipitation; Sediment; Simulation models; Streams; Water pollution; Watersheds; Coastal areas; Fishes; Indicator species; Reproduction Abstract: There is increasing concern over the possibility of adverse cumulative watershed effects from intensive forest management. It is impractical to address many aspects of the problem experimentally because to do so would require studying large watersheds for 100 yr or more. One such aspect is the long-term effect of forest management strategies on erosion and sedimentation and the resultant damage to fish habitat. Is dispersing activities in time and space an effective way to minimize cumulative sedimentation effects? To address this problem, Monte Carlo simulations were conducted on four hypothetical 10 000-ha fifth-order forested watersheds: one watershed was left undisturbed, one was completely clearcut and roaded in 10 yr, with cutting starting at the head of the watershed and progressing toward the mouth, another was cut at the rate of 1% each year beginning at the watershed's mouth and progressing upstream, and another was cut at a rate of 1% each year, with individual cut areas being widely dispersed throughout the watershed. These cutting patterns were repeated in succeeding centuries, rebuilding one-third of the road network every 100 yr. The parameters governing the simulations were based on recent data from coastal Oregon and northwestern California. Mass wasting, the most important source of sediment in that environment, was the only hillslope process modeled. The simulation results suggest that (i) the greatest differences between management strategies appeared in the first 100 yr and were related primarily to the rate of treatment. By the second 100 yr, when all watersheds had been treated, the principal difference between logging strategies was the timing of impacts. (ii) Dispersing harvest units did not significantly reduce cumulative effects. (iii) The frequency of bed elevation changes between 1 and 4 cm is dramatically increased by logging. 58 NAL Call.

Language: English Descriptors: Scotland; Watersheds; Afforestation; Acid deposition; Soil acidity; Soil ph; Water quality; Forests; Growth; Clearcutting; Streams; Acidification; Forest management; Cations; Soil treatment; Soil alkalinity; Simulation models Abstract: A model of the combined long-term effects of acidic deposition and forest growth has been developed and calibrated for an upland site in Scotland. The model is used to perform a series of simulation experiments to assess the relative effects of afforestation and acidic deposition on soil and surface water chemistry. The experiments compare and contrast: (a) the simulated historical effects of increased acidic deposition and forest growth, both individually and in combination; (b) the simulated future effects of various levels of reduction of deposition in combination with the forestry strategies of harvesting with and without replanting. Results indicate that historical acidification of surface waters in areas receiving high levels of acidic deposition has been exacerbated by afforestation practices. Afforestation in the absence of acidic deposition, however, has had a lesser effect on surface water acidification even though the nutrient demands of forest growth have caused significant soil acidification. Comparisons of future forest management strategies in conjunction with likely deposition reductions indicate that, in sensitive areas, replanting of a felled forest without treatment of the soil by addition of base cations, should not be undertaken even if significant deposition reductions are realised. 59 NAL Call.

Language: English Descriptors: Rhode Island; Riparian forests; Nitrates; Groundwater; Subsurface drainage; Seasonal variation; Water table; Soil depth; Ph; Soil organic matter; Temperature; Spatial variation; Groundwater pollution; Wetlands; Upland areas Abstract: This study was conducted to assess the removal of groundwater nitrate (NO3-) in different soil drainage classes within three riparian forests located in Rhode Island. A solution of NO3- and a conservative tracer [either bromide (Br-) or chloride (Cl-)] was applied in the growing and the dormant seasons to trenches upgradient of wetland locations with hydric soils (poorly and very poorly drained soils) and transition zone locations with somewhat poorly and moderately well-drained soils located immediately upslope of the wetlands. To assess removal, the change in groundwater concentrations of NO3- relative to the concentration of the conservative tracer was observed in monitoring wells located in each soil drainage class from June 1989 through April 1990. Removal of groundwater NO3- was consistently high in the wetland locations, generally in excess of 80% in both growing and dormant seasons. In the transition zones, attenuation was less than 36% during the growing season, and ranged from 50 to 78% in the dormant season. Attenuation in the transition zones was positively correlated with water table elevations. Transition zone attenuation was high in the dormant season relative to the growing season likely because high water tables during the dormant season caused the contaminant plume to be exposed to soil with higher organic matter. The results suggest that both wetlands and transition zones between wetlands and uplands can be important sinks for groundwater NO3-. 61 NAL Call.

Language: English Descriptors: Nitrates; Soil pollution; Groundwater pollution; Aquifers; Arable land; Heathland; Coniferous forests; Land use; Transport processes; Reduction; Geochemistry; Models Abstract: Nitrate distribution and reduction processes were investigated in an unconfined sandy aquifer of Quaternary age. Groundwater chemistry was studied in a series of eight multilevel samplers along a flow line, deriving water from both arable and forested land. Results show that plumes of nitrate-contaminated groundwater emanate from the agricultural areas and spread through the aquifer. The aquifer can be subdivided into an upper 10- to 15-m thick oxic zone that contains O2 and NO3(-), and a lower anoxic zone characterized by Fe2+-rich waters. The redox boundary is very sharp, which suggests that reduction processes of O2 and NO3(-) occur at rates that are fast compared to the rate of downward water transport. Nitrate-contaminated groundwater contains total contents of dissolved ions that are two to four times higher than in groundwater derived from the forested area. The persistence of the high content of total dissolved ions in the NO3(-) free anoxic zone indicates the downward migration of contaminants and that active nitrate reduction is taking place. Nitrate is apparently reduced to N2 because both nitrite and ammonia are absent or found at very low concentrations. Possible electron donors in the reduced zone of the aquifer are organic matter, present as reworked brown coal fragments from the underlying Miocene. and small amounts of pyrite at an average concentration of 3.6 mmol/kg. Electron balances across the redoxcline, based on concentrations of O2, NO3(-), SO4(2-) and total inorganic carbon (TIC), indicate that pyrite is by far the dominant electron donor even though organic matter is much more abundant. Groundwater transport and chemical reactions were modeled using the code PHREEQM, which combines a chemical equilibrium model with a one- dimensional mixing cell transport model. Only the vertical component of the water transport was modeled since, in contrast to rates along flow lines, the vertical rates are close to constant as required by the one-dimensio 62 NAL Call.

The importance of N losses via degassing of N2O from groundwater entering surface streams is unknown. Measurements of N2O in soil solution revealed patterns of seasonal and spatial variation that were consistent with ecosystem regulation of denitrification. The highest concentrations were observed in the riparian zone in May, when soil NO3-, temperature and moisture were conducive for denitrification. At each of the other sample dates and sites, at least one of these factors appeared to prevent significant N2O accumulation in soil solution. Extrapolation of the highest observed N2O concentrations to an annual basis corresponded to a loss of only 56 g N ha-1 yr-1. Denitrification in the riparian zone may be an important fate of N in this hardwood forest, but N2O in soil solution does not appear to be a significant pathway of N loss. This site might be expected to produce N2O at higher rates than most hardwood forests, but extrapolation of the highest calculated losses from soil solution over the global area occupied by hardwood forest indicates that this source of N2O is insignificant for global atmospheric budgets. 64 NAL Call.

Trajectories of time, discharge, and ion concentration suggest that patterns of nutrient flux are controlled primarily by the magnitude of streamwater discharge, and seasonal differences in the relative contributions of snowmelt and soil water. In the subalpine catchment, increased streamwater discharge accounted for most of the decline in concentration of ions, with high concentrations in soil water relative to precipitation. This relationship was not seen in the alpine catchment, probably because of the influence of large diurnal variation in the ratio of snowmelt to soil water. In both catchments, ions with comparatively high concentrations in precipitation and the snowpack relative to soil water showed less concentration decline with increased streamwater discharge. The recurring nature of the trajectories, especially in the subalpine catchment, suggests that the time, discharge, and ion concentration patterns may represent a general characteristic in moderate-sized, undisturbed Rocky Mountain catchments which do not receive high inputs of airborne contaminants. 67 NAL Call.

Language: English Descriptors: Ontario; New York; Hardwoods; Acer saccharum; Cycling; Nitrogen; Sulfur; Nitrates; Sulfates; Age of trees; Soil properties; Biogeochemistry; Mineral soils; Throughfall; Acid rain Abstract: Biogeochemical cycling of S and N was quantified at two hardwood sites (Turkey Lakes watershed (TLW) and Huntington Forest (HF)) that have sugar maple (Acer saccharum Marsh.) as the major overstory component and are underlain by Spodosols (Podzols). TLW and HF are located in central Ontario (Canada) and the Adirondack Mountains of New York (U.S.A), respectively. Major differences between the TLW and HF sites included stand age (300 and 100 years for TLW and HF, respectively), age of dominant trees (150-300 and 100 years for TLW and HF, respectively), and the presence of American beech (Fagus grandifolia Ehrh.) at HF as well as lower inputs of SO4(-2) and NO3(-) (differences of 99 and 31 mol ion charge (molc).ha-1.year-1, respectively) at TLW. There was an increase in concentration of SO4(-2) and NO3(-) after passage through the canopy at both sites. A major difference in the anion chemistry of the soil solution between the sites was the much greater leaching of NO3(-) at TLW compared with HF (1300 versus 18 molc.ha-1.year-1, respectively). At HF, but not TLW, there was a marked increase in SO4(-2) flux (217 molc.ha-1.year-1) when water leached from the forest floor through the mineral soil. The mineral soil was the largest pool (> 80%) of N and S for both sites. The mineral soil of TLW had a C:N ratio of 16:1, which is much narrower than the 34:1 ratio at HF. This former ratio should favor accumulation of NH4(+) and NO3(-) and subsequent NO3(-) leaching. Laboratory measurements suggest that the forest floor of TLW may have higher N mineralization rates than HF. Fluxes of N and S within the vegetation were generally similar at both sites, except that net requirement of N at TLW was substantially lower (difference of 9.4 kg N.ha-1.year-1). The higher NO3(-) leaching from TLW compared with HF may be attributed mostly to stand maturity coupled with tree mortality, but the absence of slow decomposing beech leaf litter and lower C:N ratio in die soil of the former site 68 NAL Call.

Water resources bulletin v. 28 (5): p. 845-852; 1992 Sep. Includes references. Language: English Descriptors: Oregon; Watersheds; Watershed management; Logging; Logging effects; Water quality; Decision making; Case studies Abstract: Most forest lands are managed for multiple purposes, among them timber production and water supply. Conflicts often arise in such caws because logging is perceived as a threat to water quality. These conflicts can result from uncertain factual information, from differences in underlying social values, or from imbalances in the incidence of costs and benefits. Resulting conflicts may go unresolved because existing institutional structures fail to address the real roots of the dispute. When such conflicts go unresolved, benefits are often lost, and social, political, and managerial costs are high. This study found that the roots of conflict may lie in value differences or in interest impacts, but attention may be focused inappropriately and unproductively on factual issues. It suggests that at least some long-standing disputes in the management of forested watersheds may be resolved by identifying the root causes of these disputes and choosing those actions, whether they be changes in management guidelines or altered institutional structures, which are appropriate to those causes. 73 NAL Call.

Language: English Descriptors: Pueraria lobata; Weed control; Picloram; Pinus palustris; Leaching; Pesticide persistence; Mineral soils; Soil solution; Stream flow; Environmental pollution; Aerial application Abstract: Picloram (4-amino-3,5,6-trichloropicolinic acid) was aerially applied to a longleaf pine (Pinus palustris L.) site in the upper coastal plain of Alabama to control kudzu [Pueraria lobata (Willd.) Ohwi]. Pellets (10% a.i.) were spread at the rate of 56 kg ha-1 on loamy sand Typic Kanhapludult soils. Movement of this herbicide was monitored with mineral soil samples, tension-cup lysimeters, flowproportional streamflow samplers, and discrete samplers. Picloram levels in the upper 15 cm of mineral soil peaked at 0.96 to 2.25 mg kg-1 25 d after application, depending on slope position, and declined to 0.13 to 0.29 mg kg-1 1 yr later. In soil solution, picloram was detected at a depth of 0.4 m between 26 and 273 d after application. Only 4 of 15 lysimeters consistently contained detectable residues. Maximum picloram levels in soil solution were 130, 450, and 191 mg m-3 for ridge, midslope, and toe-slope positions, respectively. Downstream monitoring began 4 d after the herbicide application, and an initial concentration of 68 mg m-3 of picloram was detected. The maximum downstream concentration of 77 mg m-3 occurred 18 d after the application, immediately after the second storm event. Downstream levels dropped to less than 10 mg m-3 after 90 d and to less than 2 mg m-3 after 200 d. Following localized retreatment along the stream more than a year after the initial treatment, levels climbed again into the 20 to 30 mg m-3 range. Most of the initial off-site movement came from a perennial stream the had been inadvertently treated, but subsequently storm runoff was the largest contributor to stream contamination. Picloram residues in this stream were similar to those observed downstream, but they were higher (up to 241 mg m-3 and dropped faster to below 2 mg m-3 after D 150. 74 NAL Call.

Neal and M. Hornung, guest editors. Includes references. Language: English Descriptors: Wales; Soil water; Streams; Hill land; Coniferous forests; Solutes; Sulfates; Nitrate; Aluminum; Hydrogen ions; Recharge; Ion transport; Water quality; Storms; Runoff; Movement in soil Abstract: Streams draining coniferous forests are often loaded with solutes such as hydrogen ion, sulphate, nitrate and aluminium. As a result, fish populations can be reduced and water quality may fall below recommended potable standards. The transport of ions into water-courses is governed by the movement of water. Within most temperate and tropical areas the stream discharge and chemistry, during periods of rapid runoff, is dominated by the exfiltration of water and solutes from stream-side soils. The movement of water to stream-side or 'riparian' areas remains, however, an enigma. This paper attempts to explain how the riparian area might be rapidly recharged during storm events. Two analytical techniques, the free-surface method and tangent-continuity method, are applied to hydrological properties monitored on a steep coniferous hillslope, during a selected storm event. Comparison of the ionic concentrations of waters within each component of the hydrological system, is used to verify the hydrological analysis. Perched water-tables developed within the basal zones of the O/Ah and Eag soil horizons of the steep podzolic hillslope, during all major storm events. Most of the rapid response within the riparian zone could be explained by lateral flow in these near-surface soil horizons, particularly in the saturated basal zones. This pathway is corroborated by the similarity of riparian zone and near-surface (or topsoil) chemistries. Relatively low concentrations of monomeric aluminium and relatively high concentrations of chloride, sodium and hydrogen ion were observed within these zones, compared with the subsoil (Bsl and B/C) horizons. 76 NAL Call.

Language: English Descriptors: Minnesota; Vegetation; Forest trees; Plant ecology; Plant succession; Species diversity; Bogs; Fens; Peatlands; Peat; Stratigraphy; Peat soils; Soil analysis; Water quality; Surface water Abstract: (1) Two peat mounds have developed in the Lost River peatland of northern Minnesota. One has the chemical and physical properties of an extremely rich fen and the other has the properties of a raised bog. The two mounds are separated by a water track with poor-fen vegetation and chemistry. (2) The vegetation at Lost River can be divided into five noda that correspond to landform units: spring-fen channel, spring- fen forest, marginal swamp forest, water track, and raised bog. These vegetation types have well-defined ranges for pH and calcium concentration. (3) Ordinations of the vascular plant and bryophyte data indicate a close relationship between the vegetation and both moisture and chemical gradients. The link between vegetation and chemistry is also supported by plots of species richness vs. pH and calcium concentration in which the peak in species numbers occurs within the rich-fen range. (4) The chemistry of the surface waters at Lost River is largely determined by the mixing of alkaline groundwater with precipitation, because the entire peatland is located at least seasonally within a discharge zone for groundwater. Mixing models indicate that the amount of groundwater within the surface waters ranges from 50% in the spring-fen channels to 1% on the raised bog. (5) The development of the two peat mounds was reconstructed from peat cores collected near the crests of the spring-fen mound and raised bog. The raised bog developed over a depression, which was first filled in with fen peat before minerotrophic sphagna invaded the site around 2625 B.P. By 2200 B.P. all fen indicator species had disappeared and the site was dominated by assemblages similar to those in the present raised bog. (6) The spring-fen mound, however, developed over a rise in the mineral substrate, which was not covered by peat until 3000 B.P. The mound was quickly colonized by Sphagnum and no fen indicators appeared until 1160 B.P. At this time the bog vegetation was replaced by a sedge fe 81 NAL Call.

Language: English Descriptors: New Zealand; Pinus radiata; Afforestation; Watersheds; Catchment hydrology; Streams; Riparian forests; Water quality; Sediment; Nitrogen; Water yield; Phosphorus; Pastures; Transpiration; Water flow; Interception; Runoff; Overland flow Abstract: The flow records for two pasture headwater catchments for 9 yr before, and 9 yr after riparian afforestation in one catchment were compared. Average rainfall was 1021 mm per yr. Riparian afforestation reduced water yields by 68 to 104 mm (21-55%) when the Pinus radiata stand was 8 to 10 yr old. Delayed runoff declined by 52 to 93 mm per yr (27-63%). Afforestation reduced the quickflow yield in 1 yr (22 mm or 40%). Peak flows declined in small events, were not affected in medium-sized events, and may have increased in large events. The large reductions in yield indicate that the riparian zone had a disproportionately important influence on catchment hydrology. They are attributed to high transpiration losses from the riparian pine in seasons with water deficits, and higher than usual forest interception losses because of the small-scale planting. Streamwater sediment, total and dissolved N and P concentrations in these two catchments and another riparian afforested catchment were monitored for 2 yr. Concentrations were generally lower in the completely pastured catchment. Estimated annual sediment, total P, Kjeldahl N, and nitrate exports from the pasture catchment were 31 to 60%, 70%, 61 to 64% and 58 to 74% of those from the riparian afforested catchments in spite of a higher water yield. Possible explanations for the poor water quality in riparian afforested catchments are described including the lack of riparian wetlands, in-stream vegetation, and close riparian ground cover. The consequences of riparian afforestation in pasture catchments may not readily be predicted from the impacts of complete catchment afforestation. 83 NAL Call.

Language: English Descriptors: Spain; Watersheds; Broadleaved evergreen forests; Streams; Water quality; Water content; Chemical properties; Stream flow; Seasonal variation; Discharge; Solutes; Ions; Soil water; Groundwater; Temperature; Catchment hydrology; Mediterranean climate; Mathematical models Abstract: Streamwater chemistry is described for three streams draining undisturbed, evergreen broad-leaved forested catchments on phyllites in NE Spain: two streams with no or negligible flow in summer are located in the Prades massif, and one perennial stream is in the wetter Montseny mountains. Weekly data for a study period of 24 years are provided to (1) describe the seasonal variations in streamwater chemistry, (2) analyse the relationship between stream discharge and solute concentrations using a two-component mixing model and (3) search for patterns of temporal variation in stream solute concentrations after discounting the effects of discharge. At Prades, concentrations of all analysed ions, except NO3(-1), showed marked seasonal variations in stream water, whereas at Montseny only ions related to mineral weathering (HCO3(-1), Na+, Ca2+ and Mg2+) showed strong seasonality. Ion concentrations were more closely dependent on instantaneous discharge at Montseny than at Prades. The residuals of the relationship between solute concentrations and discharge retained a strong seasonality at Prades, but not at Montseny. These differences are related to the major hydrochemical processes that determine the streamwater chemistry at each site. The same processes are probably operative in the three catchments, but are of varying relative importance. At Montseny, the mixing of waters of different chemical composition seems to be the major process controlling streamwater chemistry, although the soilwater end-member composition predicted by the mixing model applied did not match the measured soilwater chemistry. In the drier Prades catchments, the two major hydrochemical processes determining the seasonal variation of streamwater chemistry are (1) the restart of flow after the summer drought, which flushes out the solutes accumulated during the dry period, and (2) the seasonal changes in groundwater chemistry that result from the interplay of water residence time, temperature and CO 88 NAL Call.

The isotopic pattern for rainfall is similar for both areas: there is a wide range in isotopic contents and the results show a strong, near-linear trend, delta(2)H = 7.9 X delta(18)O + 9.8 (N = 59; r(2) = 0.952), the 'local meteoric line'. There is slight curvature to the data which may be related to the sources of water vapour forming the rainfall. Within the streams, the isotopic variability is much less than that of the rainfall although the data lie on, or very near to, the meteoric line. Data for detailed collections during storm events show more scatter than those collected regularly on a fortnightly basis. The event data show a linear feature that conforms to the local meteoric fine. These results indicate that: (1) the main supply of water to the stream stormflow comes from water stored in the catchment prior to the event; (2) waters of more than one isotopic composition reside within the catchment and are transferable to the stream during storm events; (3) the main process of water transfer from the catchment back to the atmosphere comes from transpiration by the trees and (possibly) complete evaporation from the near-surface soil horizons and the tree canopy; (4) the isotopic technique cannot be used for quantitative hydrograph separation in this instance--at least two water types can be present within the catchment at any given time. 93 NAL Call.

Four groups of variables are identified as having contrasting behaviour: alkalinity and pH; nitrate and potassium; sulphate and chloride; sodium, calcium and magnesium. The results show a complex pattern of response to flow that can be broadly linked to: (1) antecedent hydrological conditions; (2) rainfall intensity; (3) supplies of water from chemically distinct areas within the catchment. However, comparisons between this study and a parallel one which examined the composition of waters within the catchment, show that it is presently impossible to quantify the relative supplies from each part of the catchment. The findings are reviewed in relation to analogous studies within a European setting and in relation to modelling initiatives. 95 NAL Call.

Language: English Descriptors: Ontario; Acer saccharum; Betula alleghaniensis; Nitrates; Runoff water; Streams; Water composition and quality; Soil solution; Cations; Leaching Abstract: Temporal variations in soil solution and stream chemistry were examined in 1984 in an undisturbed sugar maple- yellow birch (Acer saccharum Marsh.-Betula alleghaniensis Britton) forest in the Turkey Lakes Watershed, Ontario. Nitrate was the dominant anion associated with cation depletion from soil. Nitrogen in precipitation was less important than soil N in the determination of solution chemistry. Growing-season increases in NH+4 and NO-3 in soil solution were greatest in the Oe horizon and decreased with depth. Nitrate concentrations in mineral soil solution and streamwater were highest during the dormant period and peaked at the start of spring snowmelt. Althouhg NO-3 concentrations in streamwater were positively correlated (r = 0.7-0.9) with NO-3 and Ca2+ concentrations in mineral soil solution during the dormant period, NO-3 contributed far less to cation fluxes in streamwater than HCO-3 or SO(2/4). 100 NAL Call.

Language: English Descriptors: England; Pinus; Quercus; Alnus; Picea; Rain; Water quality; Chemicals; Throughfall; Soil water; Forest litter; Canopy; Acidity Abstract: A study was made of the changes and variation in the chemistry of rainwater passing through the different strata of separate ecosystems of four tree species (oak, aider, spruce and pine) on the same site at Gisburn (Bowland Forest), north-west England. Waters were sampled as rain, throughfall, forest-floor leachate and soil waters from both the A and B/C horizons; and analysed for NH4-N, NO3-N, PO4-P, K, Ca, Mg, Na, Al, SO4-S, Cl, total organic carbon and pH. Species differences--often marked ones--appear to exist in the concentrations of most solutes in most strata. The between- species differences in throughfall chemistry provide little guide to the chemistry of waters lower down the profile: the forest floor is a particularly important source of further species differences, e.g. variation in NO3 production and the resulting effects on acidity and other ions. The chemistry of the soil waters provides some indication of possible drainage losses, although the question of which horizon acts as the source of drainage waters on this site remains unanswered. The levels of H and Al, in particular, are very different between the upper mineral soil (A horizon) and the lower B/C horizon. In general, and based on these concentration data only, oak is associated with smallest potential solute losses, pine the greatest. 103 NAL Call.

Mulder, J.; Pijpers, M.; Christophersen, N. Washington, D.C. : American Geophysical Union; 1991 Nov. Water resources research v. 27 (11): p. 2919-2928; 1991 Nov. Includes references. Language: English Descriptors: Norway; Soil water movement; Streams; Surface water; Water flow; Soil solution; Soil types; B horizons; Aluminum; Exchangeable cations; Soil chemistry; Catchment hydrology; Acid rain; Acidification; Spatial distribution Abstract: The dynamic pattern of soil water transport is a major factor in determining the chemistry of streamwater. In the acidified Birkenes catchment (southernmost Norway) the streamwater chemistry is, to a first approximation, explained by mixing solutions from the forest floor, the B horizon and the deep peat, in various proportions depending on the hydrological conditions. Paradoxically, a direct physical contact between the forest floor and the B horizon on the one hand and the stream on the other is lacking, as the stream banks largely consist of peats. To investigate this paradox, soils and their levels of exchangeable cations were studied in a 100 m X 100 m grid. Results indicate that the exchange sites of the surface peat along the stream are significantly enriched in Al, probably due to return flow of Al-rich B horizon water. This view is supported by the similarity of the solution chemistry in surface peats and B horizons. Exchangeable base cations dominate in the forest floor upslope. Forest floor solutions, an important component of streamwater during intensive storms, are depleted in Al and may bypass the Al-enriched surface peats via ephemeral flow channels. A parallel study in a pristine catchment in mid- Norway shows a similar accumulation of Al in return flow areas. This indicates that acid deposition is not a prerequisite for elevated levels of exchangeable Al in the surface organic layers of return flow areas. 104 NAL Call.

They are 1) individuals; 2) libraries, other information centers, and commercial organizations; and 3) foreign libraries, information centers, and commercial organizations. Available services for each user category are given below. For information on electronic access for interlibrary loan requests, the "Interlibrary Loan" file. 1) DOCUMENT DELIVERY SERVICES TO INDIVIDUALS The National Agricultural Library (NAL) supplies agricultural materials not found elsewhere to other libraries. Filling requests for materials readily available from other sources diverts NAL's resources and diminishes its ability to serve as a national source for agricultural and agriculturally related materials. Therefore, NAL is viewed as a library of last resort. SUBMIT REQUESTS FIRST TO LOCAL OR STATE LIBRARY SOURCES PRIOR TO SENDING TO NAL. In the United States, possible sources are public libraries, land-grant university or other large research libraries within a state. In other countries submit requests through major university, national, or provincial institutions. If the needed publications are not available from these sources, submit requests to NAL with a statement indicating their non-availability. Submit one request per page following the instructions for libraries below. NAL'S DOCUMENT DELIVERY SERVICE INFORMATION FOR THE LIBRARY The following information is provided to assist your librarian in obtaining the required materials. LOAN SERVICE -- Materials in NAL's collection are loaned only to other U.S. libraries. Requests for loans are made through local public, academic, or special libraries. The following materials are not available for loan: serials (except USDA serials); rare, reference, and reserve books; microforms; and proceedings of conferences or symposia. Photocopy or microform of non-circulating publications may be purchased as described below. DOCUMENT DELIVERY SERVICE -- Photocopies of articles are available for a fee. Make requests through local public, academic, or special libraries. The library will submit a separate interlibrary loan form for each article or item requested. If the citation is from an NAL database (CAIN/AGRICOLA, "Bibliography of Agriculture," or the NAL Catalog) and the call number is given, put that call number in the proper block on the request form. Willingness to pay charges must be indicated on the form. Include compliance with copyright law or a statement that the article is for "research purposes only" on the interlibrary loan form or letter. Requests cannot be processed without these statements. Please read copyright notice below. CHARGES: * Photocopy, hard copy of microfilm and microfiche - $5.00 for the first 10 pages or fraction copied from a single article or publication. $3.00 for each additional 10 pages or fraction. * Duplication of NAL-owned microfilm - $10.00 per reel. * Duplication of NAL-owned microfiche - $5.00 for the first fiche and $ .50 for each additional fiche per title. BILLING - Charges include postage and handling, and are subject to change. Invoices are issued quarterly by the National Technical Information Service (NTIS), 5285 Port Royal Road, Springfield, VA 22161. Establishing a deposit account with NTIS is encouraged. DO NOT SEND PREPAYMENT. Send Requests to: USDA, National Agricultural Library Document Delivery Services Branch, ILL, PhotoLab 10301 Baltimore Blvd., NAL Bldg. Beltsville, Maryland 20705-2351 Contact the Head, Document Delivery Services Branch in writing or by calling (301) 504-5755 with questions or comments about this policy. 3) DOCUMENT DELIVERY SERVICES AVAILABLE TO FOREIGN LIBRARIES, INFORMATION CENTERS AND COMMERCIAL ORGANIZATIONS. The National Agricultural Library (NAL) accepts requests from libraries and other organizations in accordance with the national and international interlibrary loan code and guidelines. In its national role, NAL supplies copies of agricultural materials not found elsewhere. Filling requests for materials readily available from other sources diverts NAL's resources and diminishes its ability to serve as a national source for agricultural and agriculturally related materials. Therefore, NAL is viewed as a library of last resort. Submit requests to major university libraries, national or provincial institutions or network sources prior to sending requests to NAL. If the needed publications are not available from these sources, submit requests to NAL with a statement indicating their non-availability. AGLINET -- Requesters in countries with an AGLINET library are encouraged to make full use of that library and its networking capabilities. As an AGLINET participant, NAL provides free document delivery service for materials published in the United States to other AGLINET participants. REQUESTS -- Submit requests on the American Library Association (ALA) or the International Federation of Library Associations and Institutions (IFLA) interlibrary loan form or via electronic mail or telefacsimile (see over for more details). Include the complete name of the person authorizing the request on each form; the standard bibliographic source which lists the title as owned by NAL; and the call number if the citation is from an NAL database(CAIN/AGRICOLA, "Bibliography of Agriculture", or the NAL catalog). DOCUMENT DELIVERY SERVICE -- Submit a separate completed interlibrary loan form for each article requested. Indicate willingness to pay charges on the form, and compliance with copyright law or include a statement that the article is for "research purposes only". Requests cannot be processed without these statements. Please read copyright notice below. CHARGES: * Photocopy, hard copy of microfilm and microfiche - $5.00 for the first 10 pages or fraction copied from a single article or publication. $3.00 for each additional 10 pages or fraction. * Duplication of NAL-owned microfilm - $10.00 per reel. * Duplication of NAL-owned microfiche - $5.00 for the first fiche and $ .50 for each additional fiche per title. BILLING - Charges include postage and handling, and are subject to change. Invoices are issued quarterly by the National Technical Information Service (NTIS), 5285 Port Royal Road, Springfield, VA 22161. Establishing deposit account with NTIS is encouraged.
