No significant differences were found between years (P>0.05). The pooled mean was 388 kg/ha in harvested fields and 276 kg/ha in burned fields. These values are less than estimates previously available. The values for harvested fields both years were no different (P>0.05) than values obtained by the U.S. Department of Agriculture (USDA). Surveys of rice fields in December both years showed that most fields were left either harvested (26-32%) or burned (37-40%) through the winter. Fields flooded for duck hunting made up 15% of the total. The proportion of fields plowed by December increased from 14% in 1985 to 22% in 1986. Sixty-three percent of all fields that had been flooded for hunting were drained within two weeks after the end of the hunting season. Harvest yield field size levee type (contour, lasered), straw status (spread, windrowed), harvest date, and rice variety did not affect the quantity of seeds remaining after harvest (P>0.05). One harvester model, the Hardy Harvester, left more rice in fields than did others we tested (P<0.001). Specific management programs are recommended to mitigate annual variation in rice seed availability to waterfowl caused by differences in total hectares grown (15% less in 1986) and in the proportion of fields burned and plowed.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"California Fish and Game","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Miller, M.R., Sharp, D., Gilmer, D., and Mulvaney, W., 1989, Rice available to waterfowl in harvested fields in the Sacramento Valley, California: California Fish and Game, v. 75, no. 2, p. 113-123.","productDescription":"p. 113-123","startPage":"113","endPage":"123","numberOfPages":"10","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":134358,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"75","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699f0f","contributors":{"authors":[{"text":"Miller, M.

These relations, similar to those sought in regionalization studies, are computed by evaluating the conditional distribution of model output given basin and storm characteristics. This method of conditioning provides a general way of examining model sensitivity to various components of model input. The resulting relations may be expected to resemble corresponding relations obtained by regionalization using actual runoff to the extent that the rainfall-runoff model and the model input specification are physically realistic. The probabilistic description of model input is an extension of so-called \"random-model\" of channel networks and involves postulating an ensemble of basins and associated probability distributions that mimic the variability of basin characteristics seen in nature. Application is made to small basins in the State of Wyoming. Parameters of the input variable distribution are estimated using data from Wyoming, and basin-scale relations are estimated both, parametrically and nonparametrically using model-generated runoff from simulated basins. Resulting basin-scale relations involving annual flood quantiles are in reasonable agreement with those presented in a previous regionalization study, but error estimates are smaller than those in the previous study, an artifact of the simplicity of the rainfall-runoff model used in this paper. We also obtain relations for peak of the instantaneous unit hydrograph which agree fairly well with theoretical relations given in the literature. Finally, we explore the issues of sensitivity of basin-scale, relations and error estimates to parameterization of the model input probability distribution and of how this sensitivity is related to making inferences about a particular ungaged basin. ?? 1989 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Stochastic Hydrology and Hydraulics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF01544076","issn":"09311955","usgsCitation":"Troutman, B., Karlinger, M., and Guertin, D., 1989, Basin-scale relations via conditioning: Stochastic Hydrology and Hydraulics, v. 3, no. 2, p. 111-133, https://doi.org/10.1007/BF01544076.","startPage":"111","endPage":"133","numberOfPages":"23","costCenters":[],"links":[{"id":224213,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":205455,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF01544076"}],"volume":"3","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059eff0e4b0c8380cd4a519","contributors":{"authors":[{"text":"Troutman, B.M.","contributorId":73638,"corporation":false,"usgs":true,"family":"Troutman","given":"B.M.","email":"","affiliations":[],"preferred":false,"id":371335,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Karlinger, M.R.","contributorId":95039,"corporation":false,"usgs":true,"family":"Karlinger","given":"M.R.","affiliations":[],"preferred":false,"id":371336,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Guertin, D.P.","contributorId":36264,"corporation":false,"usgs":true,"family":"Guertin","given":"D.P.","email":"","affiliations":[],"preferred":false,"id":371334,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

If the shoaling region near the coast is narrow compared to the scale of the headland, bottom friction causes the flow to separate just downstream of the point where the pressure gradient switches from favoring to adverse. As long as the shoaling region at the coast is well resolved, the inclusion of eddy viscosity and a no-slip boundary condition have no effect on this result. An approximate analytic solution for the pressure gradient along the boundary is obtained by assuming the flow away from the immediate vicinity of the boundary is irrotational. On the basis of the pressure gradient obtained from the irrotational flow solution, flow separation is a strong function of the headland aspect ratio, an equivalent Reynolds number, and a Keulegan-Carpenter number.","conferenceTitle":"Estuarine and Coastal Modeling - Proceedings of the Conference","conferenceDate":"November 15-17, 1989","conferenceLocation":"Newport, RI","language":"English","publisher":"American Society of Civil Engineers","publisherLocation":"Boston, MA, United States","isbn":"0872627586","usgsCitation":"Signell, R.P., 1989, Flow separation of currents in shallow water, Estuarine and Coastal Modeling - Proceedings of the Conference, Newport, RI, November 15-17, 1989, p. 278-290.","startPage":"278","endPage":"290","numberOfPages":"13","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":223926,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1252e4b0c8380cd54271","contributors":{"authors":[{"text":"Signell, Richard P. rsignell@usgs.gov","contributorId":1435,"corporation":false,"usgs":true,"family":"Signell","given":"Richard","email":"rsignell@usgs.gov","middleInitial":"P.","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":370520,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

To obtain these data, a special instrument was designed. The instrument is a combination of a gas permeameter (for air permeability determination), a suction plate apparatus (for retentivity curve determination), and an air pycnometer (for trapped-air-volume determination). This design allowed values of air permeability, matric pressure, and air trapping to be codetermined, i.e., determined at the same values of water content using the same sample and the same inflow-outflow boundaries. Such data were obtained for two nonswelling soils. The validity of the air permeability determinations was repeatedly confirmed by rigorous tests of Darcy's law. During initial drying from complete water saturation, supplementary measurements were made to assess the magnitude of gas slip. The extended Darcy equation accurately described the measured flux gradient relations for each condition of absolute gas pressure tested. Air permeability functions exhibited zero-permeability regions at high water contents as well as an abruptly appearing hysteresis at low water contents. Measurements in the zero-permeability regions revealed that the total amount of air in general exceeded the amount of trapped air. This indicates that the medium' s air space is partitioned into three measurable domains: through-flowing air, locally accessible air (i.e., air accessible from only one flow boundary), and trapped air. During repeated wetting and drying, the disappearance and reappearance of air permeability coincided closely with the reappearance and disappearance, respectively, of trapped air. The observed relation between critical features of the air permeability functions and those of the air-trapping functions suggest that water-based blockages play a significant role in the disruption of gas-phase connectivity and in preventing air flow, and must be considered in any effectual model of air permeability relations.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/WR025i009p01959","usgsCitation":"Stonestrom, D.A., and Rubin, J., 1989, Air permeability and trapped-air content in two soils: Water Resources Research, v. 25, no. 9, p. 1959-1969, https://doi.org/10.1029/WR025i009p01959.","productDescription":"11 p.","startPage":"1959","endPage":"1969","costCenters":[],"links":[{"id":224231,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"9","noUsgsAuthors":false,"publicationDate":"2010-07-09","publicationStatus":"PW","scienceBaseUri":"5059e918e4b0c8380cd480bf","contributors":{"authors":[{"text":"Stonestrom, David A. 0000-0001-7883-3385 dastones@usgs.gov","orcid":"https://orcid.org/0000-0001-7883-3385","contributorId":2280,"corporation":false,"usgs":true,"family":"Stonestrom","given":"David","email":"dastones@usgs.gov","middleInitial":"A.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":369806,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rubin, Jacob","contributorId":23918,"corporation":false,"usgs":true,"family":"Rubin","given":"Jacob","email":"","affiliations":[],"preferred":false,"id":369805,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Furthermore, the model predicts travel times within 100 ms of the reflection times recorded from the base of the Quaternary on the Chugach reflection section. Thicknesses of Quaternary deposits, with velocities between 1.1 and 2.0 km/s, correlate inversely with the quantity of observed lower crustal reflections on the Chugach section, suggesting that the presence or absence of these sediments in sufficient thickness exerted primary control on the quality of the deeper portion of the section. There is a significant velocity contrast between crystalline rocks across the Border Ranges fault (5.0 versus 5.6 km/s), the major contact between the Chugach and Peninsular terranes, in agreement with laboratory measurements of field specimens. In the Peninsular terrane the modeling indicates that an unnamed fault delimiting the southern flank of the Copper River Basin dips steeply northward at 50° and has about 1300 m of vertical offset. Laboratory measurements document a maximum velocity anisotropy of 20% for phyllitic schists of the Valdez Group in the Chugach terrane. In agreement with the observed E-W strike and near-vertical dip of the Valdez Group, we determined a significant (14%) velocity anisotropy for ray paths oriented N-S versus NE-SW.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB094iB04p04441","issn":"01480227","usgsCitation":"Brocher, T., Fisher, M.A., Geist, E., and Christensen, N., 1989, A high-resolution seismic reflection/refraction study of the Chugach-Peninsular terrane boundary, southern Alaska: Journal of Geophysical Research Solid Earth, v. 94, no.

The injection zone was 98 m thick with a radial hydraulic conductivity of 762 m/d and a vertical hydraulic conductivity of 152 m/d. Mean chloride concentrations of the injectant during two tests of 91 and 366 days duration were 180 and 170 mg/L, respectively, whereas chloride concentration of native salt water ranged from 19,000 to 20,000 mg/L. During the 366-day test, chloride concentration in water from a well open to the upper part of the injection zone 223 m from the injection well approximately stabilized at about 4000 mg/L. Relatively constant chloride concentrations in water from this observation well at a level significantly greater than the injectant concentration suggested the hypothesis that circular convection with saltwater flow added chloride ions to the injection zone flow sampled at the observation well. In order to assess the acceptability of the circular convection hypothesis, information was required about the velocity field during injection. Mass transport model simulations were used to provide this information, after determining that the fractured injection zone could be treated as an equivalent porous medium with a single porosity. The mass transport model was calibrated using the 91-day test data from two observation wells 223 m from the injection well. The model was then run without parameter changes to simulate the 366-day test. Mass fractions of injectant computed for four observation wells during the 366-day test compared favorably with observed mass fractions. Observed mass fractions were calculated as a function of chloride concentration and density. Comparisons between model-computed mass fraction and velocity fields in a radial section showed circular convection, with salt water flowing toward the injection well in the lower part of the injection zone. The salt water then mixed with the injectant, and the mixture flowed away from the injection well in the upper part of the injection zone. On the basis of the model results and the assumed reasonableness of treating the injection zone as an equivalent porous medium with a single porosity, the hypothesis of circular convection with saltwater flow during subsurface injection of liquid waste into a highly transmissive saltwater-bearing fractured dolomite was judged acceptable.</span><br></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/WR025i007p01481","usgsCitation":"Hickey, J.J., 1989, Circular convection during subsurface injection of liquid waste, St. Petersburg, Florida: Water Resources Research, v. 25, no. 7, p. 1481-1494, https://doi.org/10.1029/WR025i007p01481.","productDescription":"14 p.","startPage":"1481","endPage":"1494","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":223435,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida","city":"St. Petersburg","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -82.8753662109375,\n              27.605670826465445\n            ],\n            [\n              -82.5238037109375,\n              27.605670826465445\n            ],\n            [\n              -82.5238037109375,\n              27.943459889766487\n            ],\n            [\n              -82.8753662109375,\n              27.943459889766487\n            ],\n            [\n              -82.8753662109375,\n              27.605670826465445\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"25","issue":"7","noUsgsAuthors":false,"publicationDate":"2010-07-09","publicationStatus":"PW","scienceBaseUri":"5059f604e4b0c8380cd4c555","contributors":{"authors":[{"text":"Hickey, John J.","contributorId":39763,"corporation":false,"usgs":true,"family":"Hickey","given":"John","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":371968,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Two methods of estimating the distribution of the aperture sizes are presented using information from a single-hole pumping test and a radially converging tracer test. The first method uses the transmissivity of the fracture and mean arrival time of the tracer, while the second method uses the mean and variance of the solute arrival time. If the fracture can be conceptualized as a series of nonintersecting flow paths of constant aperture, the two methods should yield identical estimates for the parameters of the distribution. The validity of the channel model can be assessed by comparing the parameters of the distribution that are estimated by the two methods. This technique was demonstrated using hydraulic and tracer tests conducted in a discrete, areally extensive, horizontal fracture in the Silurian dolomite in the northeastern Illinois. A lognormal and a truncated gamma distribution were used to describe the distribution of constant aperture flow paths. The lognormal distribution could not reproduce the abrupt rising limb and maximum rate of mass arrival that characterized the tracer tests. The gamma distribution more accurately predicted the shape of the breakthrough curves; however, the two methods of estimating the parameters of the distribution provided significantly different estimates of the variances of the aperture sizes. The mean aperture as estimated by the two methods was similar. The difference in the variance of the aperture as estimated by the two methods indicates that alternative conceptual models of aperture heterogeneity are required to more accurately describe both fluid and solute movement in this field situation.</span><br></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/WR025i005p00817","usgsCitation":"Shapiro, A.M., and Nicholas, J.R., 1989, Assessing the validity of the channel model of fracture aperture under field conditions: Water Resources Research, v. 25, no. 5, p. 817-828, https://doi.org/10.1029/WR025i005p00817.","productDescription":"12 p.","startPage":"817","endPage":"828","costCenters":[],"links":[{"id":223180,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"5","noUsgsAuthors":false,"publicationDate":"2010-07-09","publicationStatus":"PW","scienceBaseUri":"5059edf1e4b0c8380cd49b15","contributors":{"authors":[{"text":"Shapiro, Allen M. 0000-0002-6425-9607 ashapiro@usgs.gov","orcid":"https://orcid.org/0000-0002-6425-9607","contributorId":2164,"corporation":false,"usgs":true,"family":"Shapiro","given":"Allen","email":"ashapiro@usgs.gov","middleInitial":"M.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":371931,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nicholas, James R.","contributorId":149200,"corporation":false,"usgs":false,"family":"Nicholas","given":"James","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":371930,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The behaviour of piscivorous fish (largemouth bass, <i>Micropterus salmoides</i> and northern pike, <i>Esox lucius</i>) and their prey (bluegills, <i>Lepomis macrochirus</i>, and fathead minnows, <i>Pimephales promelas</i>) were quantified in 60-min experiments in laboratory pools (2 multiplied by 4 m in diameter, 0 multiplied by 5 m deep) with artificial vegetation at densities of 0, 50, 250, and 1000 stems/m<sup>2</sup>.  Largemouth bass switched predatory tactics from searching to ambushing as plant density increased whereas northern pike always used ambushing.  At high plant density, both predators captured minnows, but not bluegills.

The host rocks include limestones of the Triassic Cane Spring Formation, which are overlain by shales of the Triassic Grass Valley Formation. The rocks were folded and metamorphosed to greenschist grade during Jurassic and Cretaceous regional tectonic activity. Mesozoic thrusting may have occurred along the shale-limestone contact, but evidence has been obscured by later hydrothermal activity. The sedimentary rocks were nominally offset along several Late Tertiary normal faults related to uplift of the range.The upper part of the Cane Spring Formation is composed of a poorly sorted breccia composed of limestone clasts with a clay matrix. Irregular pockets within this zone are filled with clay- to pebble-sized fragments derived from the Grass Valley shale. The enclosing limestone beds were tilted moderately to the southwest during Mesozoic deformation, whereas bedding within these pockets is generally horizontal, indicating post-tilting deposition of the sediments. The sediments show graded bedding and other sedimentary features that indicate deposition from flowing water. Thermally mature carbon derived from the limestone is also concentrated in small pockets in the matrix. The breccia unit is likely the product of low-temperature solution brecciation. Ground water dissolved much of the limestone directly beneath the shales, progressively creating irregular cavities and the breccia. Sediments derived from the overlying Grass Valley shale were fiuvially deposited as a matrix to the developing solution breccia.Episodic pulses of hydrothermal fluids were introduced along faults and possibly mixed with the ground water in the breccia zone. Initially, jasperoids formed along the faults, but later hydrothermal pulses introduced gold, silica, and fluorine into both the early jasperoids and the unconsolidated cave-fill sediments to form the orebody. Continued solution-related brecciation chaotically disrupted the gold deposit.Gold, fluorite, pyrite, silver, calcite, and fine-grained silica are the principal hydrothermal minerals in the deposit. Gold was deposited as micron-sized flakes of native gold and rarely as electrum during a relatively late stage of silicification of the jasperoids, the carbon-rich zones, and the clay-rich matrix of the breccia. Fluorite was deposited with and later than the gold in the jasperoids, and it in part replaced the clay-rich breccia matrix. Antimony, arsenic, mercury, and thallium are directly associated with gold in the orebody.The deposit formed at a relatively shallow depth. On the basis of fluid inclusion data, late-stage hydrothermal fluids related to gold and fluorite deposition were extremely dilute and had temperatures near 200 degrees C. The fluid inclusions in fluorite show no evidence for boiling, but porous crackle breccias in the jasperoids suggest that hydrobrecciation took place.</span></p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.84.2.279","issn":"03610128","usgsCitation":"Wallace, A.R., 1989, The Relief Canyon gold deposit, Nevada: A mineralized solution breccia: Economic Geology, v. 84, no. 2, p. 279-290, https://doi.org/10.2113/gsecongeo.84.2.279.","productDescription":"12 p.","startPage":"279","endPage":"290","numberOfPages":"12","costCenters":[],"links":[{"id":223292,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"84","issue":"2","noUsgsAuthors":false,"publicationDate":"1989-04-01","publicationStatus":"PW","scienceBaseUri":"505ba8b3e4b08c986b321dc5","contributors":{"authors":[{"text":"Wallace, A.

Problems and concepts","docAbstract":"<p><span>Intracell flow is important in modeling cells that contain both sources and sinks. Special attention is needed if recharge through the water table is a source. One method of modeling multiple sources and sinks is to determine the net recharge per cell. For example, for a model cell containing both a sink and recharge through the water table, the amount of recharge should be reduced by the ratio of the area of influence of the sink within the cell to the area of the cell. The reduction is the intercepted portion of the recharge. In a multilayer model this amount is further reduced by a proportion factor, which is a function of the depth of the flow lines from the water table boundary to the internal sink. A gaining section of a stream is a typical sink. The aquifer contribution to a gaining stream can be conceptualized as having two parts; the first part is the intercepted lateral flow from the water table and the second is the flow across the streambed due to differences in head between the water level in the stream and the aquifer below. The amount intercepted is a function of the geometry of the cell, but the amount due to difference in head across the stream bed is largely independent of cell geometry. A discharging well can intercept recharge through the water table within a model cell. The net recharge to the cell would be reduced in proportion to the area of influence of the well within the cell. The area of influence generally changes with time. Thus the amount of intercepted recharge and net recharge may not be constant with time. During periods when the well is not discharging there will be no intercepted recharge even though the area of influence from previous pumping may still exist. The reduction of net recharge per cell due to internal interception of flow will result in a model-calculated mass balance less than the prototype.

In some cases the bias can lead to underestimation of constituent loads by as much as 50%, and several procedures have been suggested for reducing or eliminating it. However, some of the procedures recommended for reducing the bias can actually increase it. This paper compares the bias and variance of three procedures that can be used with log linear regression models: the traditional rating curve estimator, a modified rating curve method, and a minimum variance unbiased estimator (MVUE). Analytical derivations of the bias and efficiency of all three estimators are presented. It is shown that for many conditions the traditional and the modified estimator can provide satisfactory estimates. However, other conditions exist where they have substantial bias and a large mean square error. These conditions commonly occur when sample sizes are small, or when loads are estimated during high-flow conditions. The MVUE, however, is unbiased and always performs nearly as well or better than the rating curve estimator or the modified estimator provided that the hypothesis of the log linear model is correct. Since an efficient unbiased estimator is available, there seems to be no reason to employ biased estimators.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/WR025i005p00937","usgsCitation":"Cohn, T., DeLong, L.L., Gilroy, E.J., Hirsch, R.M., and Wells, D.K., 1989, Estimating constituent loads: Water Resources Research, v. 25, no. 5, p. 937-942, https://doi.org/10.1029/WR025i005p00937.","productDescription":"6 p.","startPage":"937","endPage":"942","costCenters":[],"links":[{"id":223266,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"5","noUsgsAuthors":false,"publicationDate":"2010-07-09","publicationStatus":"PW","scienceBaseUri":"505a0b11e4b0c8380cd52556","contributors":{"authors":[{"text":"Cohn, Timothy A. tacohn@usgs.gov","contributorId":2927,"corporation":false,"usgs":true,"family":"Cohn","given":"Timothy A.","email":"tacohn@usgs.gov","affiliations":[{"id":502,"text":"Office of Surface Water","active":true,"usgs":true}],"preferred":true,"id":373437,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"DeLong, Lewis L.","contributorId":91146,"corporation":false,"usgs":true,"family":"DeLong","given":"Lewis","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":373435,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gilroy, Edward J.","contributorId":50524,"corporation":false,"usgs":true,"family":"Gilroy","given":"Edward","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":373433,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hirsch, Robert M. 0000-0002-4534-075X rhirsch@usgs.gov","orcid":"https://orcid.org/0000-0002-4534-075X","contributorId":2005,"corporation":false,"usgs":true,"family":"Hirsch","given":"Robert","email":"rhirsch@usgs.gov","middleInitial":"M.","affiliations":[{"id":37316,"text":"WMA - Integrated Information Dissemination Division","active":true,"usgs":true},{"id":502,"text":"Office of Surface Water","active":true,"usgs":true},{"id":37778,"text":"WMA - Integrated Modeling and Prediction Division","active":true,"usgs":true},{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":373436,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wells, Deborah K.","contributorId":65867,"corporation":false,"usgs":true,"family":"Wells","given":"Deborah","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":373434,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

During the peak flowering season of late July to early August, individual colonies of purple loosestrife were identified and categorized into three size classes in parallel belt transects consisting of the median strip and highway rights-of-way on the north and south sides of the road. Data were also collected on the presence of colonies adjacent to the corridor and on highway drainage patterns. Although a distinct east-west density gradient existed in the corridor, it corresponded to the gradient on adjacent lands and was greatly influenced by a major infestation at Montezuma National Wildlife Refuge. The disturbed highway corridor served as a migration route for purple loosestrife, but topographic features dictated that this migration was a short-distance rather than long-distance process. Ditch and culvert drainage patterns increased the ability of purple loosestrife to migrate to new wetland sites. Management strategies proposed to reduce the spread of this wetland threat include minimizing disturbance, pulling by hand, spraying with glyphosate, disking, and mowing.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/BF01874916","usgsCitation":"Wilcox, D.A., 1989, Migration and control of purple loosestrife (Lythrum salicaria L.) along highway corridors: Environmental Management, v. 13, no. 3, p. 365-370, https://doi.org/10.1007/BF01874916.","productDescription":"6 p.","startPage":"365","endPage":"370","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":132835,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"13","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a60e4b07f02db6353ce","contributors":{"authors":[{"text":"Wilcox, Douglas A.","contributorId":36880,"corporation":false,"usgs":true,"family":"Wilcox","given":"Douglas","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":308053,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
