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.

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.

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

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.

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.

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. The increase in alum

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.

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.

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.

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

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.

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.

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.

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.

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.

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-.

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

Abstract: Nitrous oxide is soluble and can accumulate in soil
solution when gaseous diffusion is restricted. 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.

Abstract: Streamwater samples were collected during 1987-1988
from two adjacent gauged watersheds, the subalpine-alpine East
St. Louis and the Fool Creek Alpine, in the Fraser
Experimental Forest, Colorado. The study objective was to
compare the relationships between streamwater discharge and
ion concentration in alpine and alpine-subalpine watersheds at
a site receiving low inputs of atmospheric contaminants.
Streamwater discharge accounts for much of the variation in
ion concentration. 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.

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

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.

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.

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.

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

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.

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

Abstract: Results are presented of a study of stable hydrogen
and oxygen isotopes in rainfall and streamwaters for the
Montseny and Prades areas in northeastern Spain: results cover
the full year of 1991. 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.

Abstract: The results of an extensive study of streamwater
chemistry during stormflow events, for a montane Mediterranean
area, are presented. 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.

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).

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.

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.

NAL DOCUMENT DELIVERY SERVICES
June 1993
United States Department of Agriculture
National Agricultural Library
Public Services Division
Document Delivery Services Branch
Beltsville, Maryland 20705-2351
The National Agricultural Library has established document delivery service
policies for three user categories. 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. Annual billing is available to foreign
institutions on request by contacting NAL at the address below. DO NOT SEND
PREPAYMENT.
