The model assumes one factor influencing detection during point counts is the singing frequency of birds. This may be true for surveys recording forest songbirds when most detections are by sound. The model requires counts to be divided into several time intervals. We used time intervals of 2, 5, and 10 min to develop a maximum-likelihood estimator for the detectability of birds during such surveys. We applied this technique to data from bird surveys conducted in Great Smoky Mountains National Park. We used model selection criteria to identify whether detection probabilities varied among species, throughout the morning, throughout the season, and among different observers. The overall detection probability for all birds was 75%. We found differences in detection probability among species. Species that sing frequently such as Winter Wren and Acadian Flycatcher had high detection probabilities (about 90%) and species that call infrequently such as Pileated Woodpecker had low detection probability (36%). We also found detection probabilities varied with the time of day for some species (e.g. thrushes) and between observers for other species. This method of estimating detectability during point count surveys offers a promising new approach to using count data to address questions of the bird abundance, density, and population trends.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Living on the Edge -- Birds 2000: Abstracts","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Memorial University of Newfoundland","publisherLocation":"St. John's, Newfoundland, Canada","collaboration":"Program for the One Hundred and Eighteenth Stated Meeting of the American Ornithologists' Union in conjunction with the 19th Annual Meeting of the Society of Canadian Ornithologists, Societe des Ornithologistes du Canada and the British Ornithologists' Union, August 14-19, 2000.

Robust estimates of parameters such as survival rate and finite rate of population change (A) are crucial for conservation purposes and useful for studies of avian life histories. We used methods developed by Pradel (1996, Biometrics 52:703-709) to estimate A for 10 species of tropical forest lowland birds using data from a long-term (> 20 yr) banding study in Panama. These species constitute a ecologically and phylogenetically diverse sample. We present these estimates and explore if they are consistent with what we know from selected studies of banded birds and from 5 yr of estimating nesting success (i.e., an important component of A). A major goal of these analyses is to assess if the mark-recapture methods generate reliable and reasonably precise estimates of population change than traditional methods that require more sampling effort.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Living on the Edge -- Birds 2000: Abstracts","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Memorial University of Newfoundland","publisherLocation":"St. John's, Newfoundland, Canada","collaboration":"Program for the One Hundred and Eighteenth Stated Meeting of the American Ornithologists' Union in conjunction with the 19th Annual Meeting of the Society of Canadian Ornithologists, Societe des Ornithologistes du Canada and the British Ornithologists' Union, August 14-19, 2000.

If true, trends in bird populations recorded by the BBS may not be sensitive predictors of regional or continental change in songbird abundance. To test whether the approximately 60 BBS routes in Maryland representatively sample the state's habitat, a geographic information system (GIS) database was compiled of significant bird habitat identified from remotely sensed landcover and land-use information (e.g., Multi-Resolution Land Characteristics Consortiumclassified Landsat Thematic Mapper imagery, etc.). These GIS data layers were analyzed to determine the statewide acreage of identified habitats as well as the acreage in each of the major physiographic regions of Maryland. Regional and statewide totals were also extracted for the subsample of habitat within 30 m of the BBS transects. The results of the comparison of regional and statewide habitat totals with the BBS sample showed very low proportional difference for nearly all of the identified habitat parameters. For Maryland and perhaps other urbanizing states, the BBS provides an accurate sample of available songbird habitats.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Extended abstracts from BioGeo99: Applications to geospatial technology to biological sciences","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","collaboration":"http://pubs.er.usgs.gov/usgspubs/itr/itr000008, no PDF offered.

Baseline inventories involving organisms and land-use types were part of the mission in the early contracts between the Atomic Energy Commission (now the Department of Energy) and the University of Georgia prior to the establishment of the Savannah River Ecology Laboratory (SREL) as a National Environmental Research Park Laboratory. About 27% of the SREL publications during this first decade dealt with birds. Since that time, research on the SRS landscape has expanded and broadened with less than 10% of the publications dealing with birds. SRS changed also from an agriculturally dominated area with ca. 40% open areas (fields, crops, pastures) to a timber-managed area with ca. 80% forests, 12% open areas, and 2% open water impoundments. Baseline breeding bird populations of the SRS in the 1950s were typical for the region with avian species richness and density increasing with the age and succession of the vegetation (0-26 species and densities of 0-741 pairs/km2 for the habitats surveyed). During the first decade at the SRS, the resident game bird population of Northern Bobwhites (Colinus virginianus) increased and the Mourning Dove (Zenaida rnacroura) population, a migratory upland game bird, remained stable. Current avian research efforts, as well as new opportunities to reexamine the breeding bird populations and the landscape of SRS, will provide a better understanding of the potential causes of declines of neotropical migratory birds, declines of resident and migratory game birds, and how habitat influences invasions and extinctions of breeding birds in the region. Emphasis for future research and monitoring should be on neotropical migratory bird populations in decline (Yellow-billed Cuckoo, Coccyzus americanus; Eastern Wood-Pewee, Contopus virens; Wood Thrush, Hylocichla mustelina; Prairie Warbler, Dendroica discolor; and Painted Bunting, Passerina ciris), resident species in decline (e.g., Loggerhead Shrike, Lanius ludovicianus), certain species groups (e.g., waterfowl and wading birds), important habitat, and recent invasions and extinctions of breeding species. Old growth forested wetlands should be monitored because of the large number of neotropical migratory birds that depend on this habitat in the southeastern United States. A variety of survey techniques will be needed to determine population trends: line transects, call or song playbacks, roadside point surveys (call counts for game birds), aerial surveys, and presence or absence of species within stratified areas of SRS. The SRS provides opportunity for avian research at the landscape level with the potential to solve problems important to the survival of many bird populations as well as to increase our knowledge on how to manage and conserve our avian natural resources for the future.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Avian Research as the Savannah River Site: Model for integrating basic research and long-term management","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","collaboration":"This SAB has a combined Literature Cited section.

Woodcock were monitored from time of capture (25 March-15 April) to 15 June each year. To determine habitat selection by male woodcock, the following habitat characteristics were measured: land cover, age and stocking density of the forest overstory, soil drainage and texture, aspect, and percent slope. Habitat selection was examined as affected by the covariates weather and age-class of woodcock, and among years for diurnal and crepuscular periods of the breeding period. Multivariate techniques that compare use and availability of habitats were not available, so a statistical model was developed to rate importance of multiple habitat characteristics selected by woodcock. The most critical period for woodcock in terms of survival was from arrival to: mid-April. Second-year and after-second-year woodcock did not select different (P > 0.05) habitat types, but they did select different types among years and within breeding intervals (P < 0.05). In years when weather was moderate, woodcock selected young, dense stands of speckled alder (Alnus rugosa) and hardwoods, interspersed with forest openings. Suitable habitat can be maintained by creating an uneven-aged forest managed in even-aged blocks composed of several hardwood species. Managers can now quantify suitable woodcock habitat in a GIS and plan large-scale forest-harvesting strategies using data on several habitat characteristics (e.g., land cover, stand age, stocking density, soil drainage and texture, and aspect).","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the Ninth American Woodcock Symposium","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Patuxent Wildlife Research Center","publisherLocation":"Laurel, MD","collaboration":" PDF on file: see 5684_McAuley.pdf 8.8 MB","usgsCitation":"Sprankle, K., Sepik, G., McAuley, D., and Longcore, J.R., 2000, Assessing habitat selection in Spring by male American Woodcock in Maine with a geographic information system, chap. of Proceedings of the Ninth American Woodcock Symposium.","productDescription":"viii, 117","startPage":"117 (abs)","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":203103,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abbe4b07f02db672a83","contributors":{"editors":[{"text":"McAuley, Daniel G. dmcauley@usgs.gov","contributorId":5377,"corporation":false,"usgs":true,"family":"McAuley","given":"Daniel","email":"dmcauley@usgs.gov","middleInitial":"G.","affiliations":[],"preferred":true,"id":507618,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Bruggink, John G.","contributorId":34990,"corporation":false,"usgs":true,"family":"Bruggink","given":"John G.","affiliations":[],"preferred":false,"id":507619,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Sepik, Greg F.","contributorId":100055,"corporation":false,"usgs":false,"family":"Sepik","given":"Greg","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":507620,"contributorType":{"id":2,"text":"Editors"},"rank":3}],"authors":[{"text":"Sprankle, K.E.","contributorId":12601,"corporation":false,"usgs":true,"family":"Sprankle","given":"K.E.","email":"","affiliations":[],"preferred":false,"id":330084,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sepik, G.F.","contributorId":101348,"corporation":false,"usgs":true,"family":"Sepik","given":"G.F.","affiliations":[],"preferred":false,"id":330087,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McAuley, D.G. 0000-0003-3674-6392","orcid":"https://orcid.org/0000-0003-3674-6392","contributorId":15296,"corporation":false,"usgs":true,"family":"McAuley","given":"D.G.","affiliations":[],"preferred":false,"id":330085,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Longcore, J.

Return rate historically has been defined as the ratio of resighted birds to the total number banded (i.e., with bands on) the prior year, and has been used as a 'minimum number known alive' estimate of survival. Return rates potentially underestimate true survival (the complement of mortality) for two reasons. First, not every bird that returns to the study plot is actually encountered by the field researcher, and second, not every bird that survives to the next breeding season returns to the study plot. We use a branching-tree diagram to illustrate that the essential problem with return rate methodology is that the fate of birds that are not resighted is unknown. It is widely recognized that Cormack-Jolly-Seber based analyses greatly improve 'survival' estimates by incorporating the probability of resighting a bird given that it is alive and present on the study plot. However, these estimates will underestimate true survival if birds disperse beyond the range of the resighting effort. Because long-distance dispersal events are an important component of migratory bird ecology, we cannot estimate true survival from return rate data until better information on dispersal distances and probabilities are collected. We discuss several conservation implications of underestimating survival,.and suggest terminology that is potentially less confusing.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Strategies for Bird Conservation: The Partners in Flight Planning Process.

Impoundments are of three major designs: dammed ravines, excavated basins, and diked ponds. Over 50 species of wetland plants were transplanted to impoundments of Patuxent from many parts of the United States between 1945 and 1963 to determine the species best suited for establishment in tannin-stained infertile waters. The wood duck was the only waterfowl species commonly observed on the Refuge when the area was established, but Canada geese, mallards, and black ducks, were introduced and numerous techniques developed to improve nesting and brood habitat. Twenty-six waterfowl species and 80 species of other water birds have used the impoundments for resting, feeding, or nesting. Management is now conducted to optimize avian biodiversity. Management techniques include drawdowns of water every 3-5 years in most impoundments to provide maximum plant and invertebrate food resources for wildlife. Research on the impounded wetlands at Patuxent has included evaluation of vegetation in regard to water level management, improving nest box design to reduce use of boxes by starlings, imprinting of waterfowl to elevated nesting structures to reduce predation on nests, and drawdown techniques to increase macroinvertebrates. Data on waterfowl abundance are evaluated relative to management activities and a preliminary computer model for management of the impoundments has been developed. Past, present, and future management and research projects are reviewed in this paper.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Limnology and aquatic birds, monitoring, modelling and management: Second International Symposium on Limnology and Aquatic Birds, Monitoring, Modelling and Management, Merida, Yucatan, Mexico, November 24-27, 1997","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Universidad Autonoma de Yucatan","publisherLocation":"Merida, Mexico","collaboration":"OCLC: 44828344 International Symposium on Limnology and Aquatic Birds (2nd : 1997 : Merida, Yucatan, Mexico)","usgsCitation":"Perry, M., Kangas, P., and Obrecht, H., 2000, Creating and managing wetland impoundments to provide habitat for aquatic birds, chap. of Limnology and aquatic birds, monitoring, modelling and management: Second International Symposium on Limnology and Aquatic Birds, Monitoring, Modelling and Management, Merida, Yucatan, Mexico, November 24-27, 1997, p. 261-279.","productDescription":"xi, 305","startPage":"261","endPage":"279","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":203149,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db683408","contributors":{"editors":[{"text":"Comin, Francisco A.","contributorId":112528,"corporation":false,"usgs":true,"family":"Comin","given":"Francisco","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":507535,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Herrera-Silveira, Jorge A.","contributorId":112572,"corporation":false,"usgs":true,"family":"Herrera-Silveira","given":"Jorge","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":507536,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Ramirez-Ramirez, Javier","contributorId":112724,"corporation":false,"usgs":true,"family":"Ramirez-Ramirez","given":"Javier","email":"","affiliations":[],"preferred":false,"id":507537,"contributorType":{"id":2,"text":"Editors"},"rank":3}],"authors":[{"text":"Perry, Matthew C. 0000-0001-6452-9534","orcid":"https://orcid.org/0000-0001-6452-9534","contributorId":16372,"corporation":false,"usgs":true,"family":"Perry","given":"Matthew C.","affiliations":[],"preferred":false,"id":329912,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kangas, P.","contributorId":86462,"corporation":false,"usgs":true,"family":"Kangas","given":"P.","email":"","affiliations":[],"preferred":false,"id":329914,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Obrecht, H.H.

The Monitoring Avian Productivity and Survivorship (MAPS) program is a cooperative effort designed to monitor landbird demographic parameters. A principle goal of MAPS is to estimate annual survivorship and identify spatial patterns and temporal trends in these rates. We evaluated hypotheses of spatial patterns in survival rates among a collection of neighboring sampling sites, such as within national forests, among biogeographic provinces, and between breeding populations that winter in either Central or South America, and compared these geographic-specific models to a model of a common survival rate among all sampling sites. We used data collected during 1992-1995 from Swainson's Thrush (Cathorus ustulatus) populations in the western region of the United States. We evaluated the ability to detect spatial and temporal patterns of survivorship with simulated data. We found weak evidence of spatial differences in survival rates at the local scale of 'location,' which typically contained 3 mist-netting stations. There was little evidence of differences in survival rates among biogeographic provinces or between populations that winter in either Central or South America. When data were pooled for a regional estimate of survivorship, the percent relative bias due to pooling 'locations' was <1%. With the pooled data, we estimated a 44% annual regional survival rate; this low estimated survival rate was likely due to the presence of transients in the population (Rosenberg and others 1999). Using simulated data, we found that power to detect spatial differences increased considerably with number of years and spatial scale, the latter reflecting larger sample size. Detection of trends at smaller spatial scales required > 12 years of monitoring. Detection of spatial patterns and temporal trends in survival rates from local to regional scales will provide important information for management and future research directed toward conservation of landbirds.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Strategies for Bird Conservation: The Partners in Flight Planning Process.

Special emphasis was placed on the role of compost in the establishment and retention of native warm season grasses (Andropogon gerardi, Schizachyrium scoparium, and Sorghastrum nutans). This study was conducted at two sites that were degraded by previous military and farming operations. Sites were plowed twice in 1996 and then a one inch layer of COMPRO or LEAFGRO was applied with a modified manure spreader and disked into the soil to a depth of 3 inches. Vegetation sampling was conducted in 1996, 1997, 1998, and 1999. Initially the greatest vegetation cover occurred in plots treated with LEAFGRO. Plots treated with COMPRO had less vegetation cover than both types of controls plots (with and without warmseason grasses). The reduced plant growth in the plots treated with COMPRO may have been related to the much higher soil pH of these plots on both sites. In subsequent years, amounts of warm season grasses increased, however, in general there was more cover of warm season grasses in plots that did not receive compost than those that did receive compost. Sorghastrum nutans was more abundant on the sites than either of the other two species of warm season grasses. Invertebrate and mammal data collected for three years indicated that there was not more faunal activity in the plots treated with LEAFGRO or COMPRO compost soil amendments. Results indicate that compost amendments did not improve establishment of warm season grasses and the resultant faunal diversity or abundance.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the Second Eastern Native Grass Symposium held in Baltimore, Maryland, November 17-19","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Agricultural Research Service, Natural Resources Conservation Service","publisherLocation":"Beltsville, Md.","collaboration":"OCLC: 44137048","usgsCitation":"Perry, M., Osenton, P., Gough, G., and Lohnes, E., 2000, Establishment of warm season grasses with and without the use of compost soil amendments, chap. of Proceedings of the Second Eastern Native Grass Symposium held in Baltimore, Maryland, November 17-19, p. 244-248.","productDescription":"vi, 360","startPage":"244","endPage":"248","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":203146,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fdd6b","contributors":{"authors":[{"text":"Perry, Matthew C. 0000-0001-6452-9534","orcid":"https://orcid.org/0000-0001-6452-9534","contributorId":16372,"corporation":false,"usgs":true,"family":"Perry","given":"Matthew C.","affiliations":[],"preferred":false,"id":329859,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Osenton, P.C.","contributorId":20441,"corporation":false,"usgs":true,"family":"Osenton","given":"P.C.","affiliations":[],"preferred":false,"id":329860,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gough, G.A.","contributorId":105013,"corporation":false,"usgs":true,"family":"Gough","given":"G.A.","email":"","affiliations":[],"preferred":false,"id":329861,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lohnes, E.J.R.","contributorId":11728,"corporation":false,"usgs":true,"family":"Lohnes","given":"E.J.R.","email":"","affiliations":[],"preferred":false,"id":329858,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":5210987,"text":"5210987 - 2000 - Monitoring is not enough: on the need for a model-based approach to migratory bird management","interactions":[],"lastModifiedDate":"2012-02-02T00:15:29","indexId":"5210987","displayToPublicDate":"2009-06-09T09:23:18","publicationYear":"2000","noYear":false,"publicationType":{"id":5,"text":"Book chapter"},"publicationSubtype":{"id":24,"text":"Book Chapter"},"title":"Monitoring is not enough: on the need for a model-based approach to migratory bird management","docAbstract":"Informed management requires information about system state and about effects of potential management actions on system state.

I suggest that large-scale survey results (such as those derived from the North American Breeding Bird Survey) should not be used to predict population attributes on parks, refuges, and other protected areas. These areas are often managed, and generally contain habitats that can be poorly sampled in large scale surveys, hence local bird populations might be quite different from those sampled in the large-scale surveys. Furthermore, we are limited in our capabilities to combine information from local surveys with large-scale survey data. Most surveys of bird populations collect indices of abundance which are often not comparable among surveys due to habitat and region specific differences in probabilities of detecting birds. In assessing the effects of management, it is important to understand the limitations of monitoring at different geographic scales and to design programs to monitor at the scale at which management is conducted.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Strategies for Bird Conservation: The Partners in Flight Planning Process.

Recovery plans for both species advise the use of viability modeling as a tool for setting specific recovery and management targets. Population and Habitat Viability Assessment workshops were conducted to develop population targets and conservation recommendations for these species. Results of the workshops were based on modeling demographic and environmental factors, as well as discussions of management issues, management options, and public outreach strategies. The approach is intended to be iterative, and to be tracked by research and monitoring efforts. This paper discusses the consensus-building workshop process and how the approach could be useful to Partners in Flight. Population and Habitat Viability Assessments (PHVA) were used to develop population targets and conservation recommendations for Golden-cheeked Warblers (Dendroica chrysoparia) and Black-capped Vireos (Vireo atricapillus). This paper explains what PHVAs are, discusses how they are conducted, describes the general results that are produced, and suggests how Partners in Flight (PIF) might use a similar process for bird conservation planning. Detailed results of the assessments are not discussed here; however they can be found elsewhere (U. S. Fish and Wildlife Service 1996a, U. S. Fish and Wildlife Service 1996b). PHVAs were considered for Golden-cheeked Warblers and Black-capped Vireos because they are controversial, endangered species, and the species? recovery plans list PHVAs as tools to develop recovery recommendations. The U. S. Fish and Wildlife Service (USFWS) realized that the data needed to perform PHVAs for these species is limited, but that various conservation efforts, such as the Balcones Canyonlands Conservation Plan and other endeavors, were proceeding without benefit of the biological summarization and guidance that a PHVA could provide.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Strategies for Bird Conservation: The Partners in Flight Planning Process.

Assessments of current avian habitats, obtained from remotely sensed data, and the historical distribution of habitats should be used in establishing habitat objectives. Habitat planning and monitoring are best conducted using a geographic information system. Habitat objectives are assigned to three categories: maintaining existing habitat, restoring habitat, and creating new or alternative habitat. Progress toward meeting habitat objectives can be monitored through geographic information systems by incorporating georeferenced information on public lands, private lands under conservation easements, corporate lands under prescribed management, habitat restoration areas, and private lands under alternative management to enhance wildlife values. We recommend that the area and distribution of habitats within the area covered by conservation plans be reassessed from remotely sensed imagery at intervals appropriate to detect predicted habitat changes.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Strategies for Bird Conservation: The Partners in Flight Planning Process.

Valid (useful for intended purposes), current, and technically defensible stormwater-runoff models are needed to interpret data collected in field studies, to support existing highway and urban-runoffplanning processes, to meet National Pollutant Discharge Elimination System (NPDES) requirements, and to provide methods for computation of Total Maximum Daily Loads (TMDLs) systematically and economically.\r\n\r\nHistorically, conceptual, simulation, empirical, and statistical models of varying levels of detail, complexity, and uncertainty have been used to meet various data-quality objectives in the decision-making processes necessary for the planning, design, construction, and maintenance of highways and for other land-use applications. Water-quality simulation models attempt a detailed representation of the physical processes and mechanisms at a given site. Empirical and statistical regional water-quality assessment models provide a more general picture of water quality or changes in water quality over a region. All these modeling techniques share one common aspect-their predictive ability is poor without suitable site-specific data for calibration.\r\n\r\nTo properly apply the correct model, one must understand the classification of variables, the unique characteristics of water-resources data, and the concept of population structure and analysis. Classifying variables being used to analyze data may determine which statistical methods are appropriate for data analysis. An understanding of the characteristics of water-resources data is necessary to evaluate the applicability of different statistical methods, to interpret the results of these techniques, and to use tools and techniques that account for the unique nature of water-resources data sets. Populations of data on stormwater-runoff quantity and quality are often best modeled as logarithmic transformations. Therefore, these factors need to be considered to form valid, current, and technically defensible stormwater-runoff models.\r\n\r\nRegression analysis is an accepted method for interpretation of water-resources data and for prediction of current or future conditions at sites that fit the input data model. Regression analysis is designed to provide an estimate of the average response of a system as it relates to variation in one or more known variables. To produce valid models, however, regression analysis should include visual analysis of scatterplots, an examination of the regression equation, evaluation of the method design assumptions, and regression diagnostics. A number of statistical techniques are described in the text and in the appendixes to provide information necessary to interpret data by use of appropriate methods.\r\n\r\nUncertainty is an important part of any decisionmaking process. In order to deal with uncertainty problems, the analyst needs to know the severity of the statistical uncertainty of the methods used to predict water quality. Statistical models need to be based on information that is meaningful, representative, complete, precise, accurate, and comparable to be deemed valid, up to date, and technically supportable. To assess uncertainty in the analytical tools, the modeling methods, and the underlying data set, all of these components need be documented and communicated in an accessible format within project publications.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/ofr2000491","issn":"0094-9140","collaboration":"Prepared in cooperation with the Federal Highway Administration (A Contribution to the National Highway Runoff Data and Methodology Synthesis)","usgsCitation":"Tasker, G.D., and Granato, G., 2000, Statistical Approaches to Interpretation of Local, Regional, and National Highway-Runoff and Urban-Stormwater Data: U.S. Geological Survey Open-File Report 2000-491, vi, 59 p., https://doi.org/10.3133/ofr2000491.","productDescription":"vi, 59 p.","costCenters":[{"id":377,"text":"Massachusetts-Rhode Island Water Science Center","active":false,"usgs":true}],"links":[{"id":192239,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":9500,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2000/ofr00-491/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dfe4b07f02db5e3b5f","contributors":{"authors":[{"text":"Tasker, Gary D.","contributorId":95035,"corporation":false,"usgs":true,"family":"Tasker","given":"Gary","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":290879,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Granato, Gregory E. 0000-0002-2561-9913 ggranato@usgs.gov","orcid":"https://orcid.org/0000-0002-2561-9913","contributorId":1692,"corporation":false,"usgs":true,"family":"Granato","given":"Gregory E.","email":"ggranato@usgs.gov","affiliations":[{"id":466,"text":"New England Water Science Center","active":true,"usgs":true}],"preferred":false,"id":290878,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":21849,"text":"ofr00404 - 2000 - Grays Harbor Wave Refraction Experiment 1999: data report","interactions":[],"lastModifiedDate":"2012-02-02T00:07:42","indexId":"ofr00404","displayToPublicDate":"2004-05-01T00:00:00","publicationYear":"2000","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2000-404","title":"Grays Harbor Wave Refraction Experiment 1999: data report","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey,","doi":"10.3133/ofr00404","issn":"0566-8174","usgsCitation":"Gelfenbaum, G., Sherwood, C.R., Kerr, L.A., and Kurrus, K., 2000, Grays Harbor Wave Refraction Experiment 1999: data report (Version 1.0): U.S. Geological Survey Open-File Report 2000-404, 3 computer optical discs :ill.

An evaluation of data collected and analyzed by the U.S. Geological Survey and others has shown that the variation in TSS analytical results is considerably larger than that for traditional suspended-sediment concentration analyses (SSC) and that the TSS data show a negative bias when compared to SSC data. This paper presents the initial results of a continuing investigation into the differences between TSS and SSC results. It explores possible relations between these differences and other hydrologic data collected at the same stations. A general equation was developed to relate TSS data to SSC data. However, this general equation is not applicable for data from individual stations. Based on these analyses, there appears to be no simple, straightforward way to relate TSS and SSC data unless pairs of TSS and SSC results are available for a station.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Building partnerships: Proceedings of the Joint Conference on Water Resource Engineering and Water Resources Planning and Management 2000","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"Joint Conference on Water Resource Engineering and Water Resources Planning and Management 2000","conferenceDate":"July 30 - August 2, 2000","conferenceLocation":"Minneapolis, MN","language":"English","publisher":"American Society of Civil Engineers","doi":"10.1061/40517(2000)270","isbn":"9780784405178","usgsCitation":"Glysson, G.D., Gray, J.R., and Conge, L., 2000, Adjustment of total suspended solids data for use in sediment studies, in Building partnerships: Proceedings of the Joint Conference on Water Resource Engineering and Water Resources Planning and Management 2000, v. 104, Minneapolis, MN, July 30 - August 2, 2000, 10 p., https://doi.org/10.1061/40517(2000)270.","productDescription":"10 p.","costCenters":[],"links":[{"id":242965,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"104","noUsgsAuthors":false,"publicationDate":"2012-04-26","publicationStatus":"PW","scienceBaseUri":"5059e6f7e4b0c8380cd47763","contributors":{"editors":[{"text":"Hotchkiss, Rollin H.","contributorId":23653,"corporation":false,"usgs":false,"family":"Hotchkiss","given":"Rollin","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":730142,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Glade, Michael","contributorId":6154,"corporation":false,"usgs":false,"family":"Glade","given":"Michael","email":"","affiliations":[],"preferred":false,"id":730143,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Glysson, G.

The Galena-Platteville bedrock unit is a carbonate deposit of Ordovician age, composed of the Galena and Platteville Groups in Illinois and the Sinnippee Group in Wisconsin. It is the uppermost bedrock unit (subcrop) in most of northern Illinois and southern and eastern Wisconsin. The subcrop area is shaded in figure 1 of sheet 1 (Batten and others, 1997). The unit is predominately dolomite, with limestone in some areas, and has a weathered surface. Across the subcrop area, the hydrologic characteristics of the bedrock unit vary substantially. The bedrock unit may be either a confining unit or an aquifer. In areas where the Galena-Platteville bedrock unit is an aquifer, the unit is a dependable source of water for many private wells and some municipal-water-supply systems. Ground water in the Galena-Platteville bedrock aquifer is susceptible to contamination because the bedrock unit is near land surface in much of the study area, and the fractures in the unit allow rapid movement of water providing limited capacity to attenuate contaminants. The subcrop (study) area covers approximately 7,850 square miles in northern Illinois and Wisconsin. In the study area, volatile organic compounds and other contaminants have been detected in the aquifer at various sites (Mills, 1993; Kay and others, 1994). Many sources of contaminants, including landfills and industrial facilities, are known or suspected. In order to determine the possible effects of contamination on the ground-water supply, an understanding of the regional hydrogeologic framework of the Galena-Platteville bedrock unit is needed.

\n

Published and unpublished map and point data describing the geologic properties of the Galena-Platteville bedrock unit are available from many sources. The U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency (USEPA), has selected and compiled a large portion of the available data to create computer data bases and maps. The objective of this effort is to compile and publish these data in a series of reports (U.S. Geological Survey Water-Resources Investigations Reports (WRIR) 974054-A, WRIR 97-4054-B, WRIR 97-4054-C). This is the third in that series of reports. The report describes the altitude, thickness, and depth from land surface of the subcrop area of the Galena-Platteville bedrock unit.

\n

The report series will enable investigators involved in site-specific studies within the subcrop area to understand the regional geologic framework of the unit and to find additional reference sources. This report consists of four sheets that show the altitude (sheet 1), depth from land surface (sheet 2), total thickness (sheet 3), and location of altitude data (sheet 4) of the lithologic units that constitute the Galena-Platteville bedrock unit within the subcrop area. The sheets also show major known geologic features within the Galena-Platteville study area in Illinois and Wisconsin. A geographic information system (GIS) was used to generate data layers (coverages) from point data and from published and unpublished contour maps at various scales and detail.

The relation of suspended-sediment discharges to conservation-tillage practices and soil loss were analyzed for the Maumee River Basin in Ohio, Michigan, and Indiana as part of the U.S. Geological Survey’s National Water-Quality Assessment Program. Cropland in the basin is the largest contributor to soil erosion and suspended-sediment discharge to the Maumee River and the river is the largest source of suspended sediments to Lake Erie. Retrospective and recently-collected data from 1970–98 were used to demonstrate that increases in conservation tillage and decreases in soil loss can be related to decreases in suspended-sediment discharge from streams.

Average annual water and suspended-sediment budgets computed for the Maumee River Basin and its principal tributaries indicate that soil drainage and runoff potential, stream slope, and agricultural land use are the major human and natural factors related to suspended-sediment discharge. The Tiffin and St. Joseph Rivers drain areas of moderately to somewhat poorly drained soils with moderate runoff potential. Expressed as a percentage of the total for the Maumee River Basin, the St. Joseph and Tiffin Rivers represent 29.0 percent of the basin area, 30.7 percent of the average-annual streamflow, and 9.31 percent of the average annual suspended-sediment discharge. The Auglaize and St. Marys Rivers drain areas of poorly to very poorly drained soils with high runoff potential. Expressed as a percentage of the total for the Maumee River Basin, the Auglaize and St. Marys Rivers represent 48.7 percent of the total basin area, 53.5 percent of the average annual streamflow, and 46.5 percent of the average annual suspended-sediment discharge. Areas of poorly drained soils with high runoff potential appear to be the major source areas of suspended sediment discharge in the Maumee River Basin.

Although conservation tillage differed in the degree of use throughout the basin, on average, it was used on 55.4 percent of all crop fields in the Maumee River Basin from 1993–98. Conservation tillage was used at relatively higher rates in areas draining to the lower main stem from Defiance to Waterville, Ohio and at relatively lower rates in the St. Marys and Auglaize River Basins, and in areas draining to the main stem between New Haven, Ind. and Defiance, Ohio. The areas that were identified as the most important sediment-source areas in the basin were characterized by some of the lowest rates of conservation tillage.

The increased use of conservation tillage was found to correspond to decreases in suspended- sediment discharge over time at two locations in the Maumee River Basin. A 49.8 percent decrease in suspended-sediment discharge was detected when data from 1970–74 were compared to data from 1996–98 for the Auglaize River near Ft. Jennings, Ohio. A decrease in suspended-sediment discharge of 11.2 percent was detected from 1970–98 for the Maumee River at Waterville, Ohio. No trends in streamflow at either site were detected over the period 1970–98. The lower rate of decline in suspended-sediment discharge for the Maumee River at Waterville, Ohio compared to the Auglaize River near Ft. Jennings, may be due to resuspension and export of stored sediments from drainage ditches, stream channels, and flood plains in the large drainage basin upstream from Waterville. Similar findings by other investigators about the capacity of drainage networks to store sediment are supported by this investigation. These findings go undetected when soil loss estimates are used alone to evaluate the effectiveness of conservation tillage. Water-quality data in combination with soil-loss estimates were needed to draw these conclusions. These findings provide information to farmers and soil conservation agents about the ability of conservation tillage to reduce soil erosion and suspended-sediment discharge from the Maumee River Basin.

Ground-water quality was assessed in the northeastern part of the Corn Belt, where tile-drained row crops are underlain by fractured glacial till. Data were collected from 30 shallow monitor wells and 18 co-located domestic wells as part of the U.S. Geological Survey’s National Water- Quality Assessment in the Lake Erie-Lake St. Clair Basin.

Pesticides or pesticide degradates were detected in 41 percent of the monitor wells and 6 percent of the domestic wells. The pesticides detected closely correspond to those most heavily applied—herbicides used on corn and soybeans. Pesticide degradates were detected three times more frequently, and at higher concentrations, than were parent compounds. No pesticide concentration exceeded a USEPA Maximum Contaminant Level (MCL), but MCL’s have not been established for 9 of the 11 compounds detected.

Thirty-seven percent of monitor-well samples had nitrate concentrations indicative of human influences such as fertilizer, manure or septic systems. Nitrate was the only chemical constituent detected at a concentration greater than an MCL. The MCL was exceeded in 7 percent of samples from monitor wells which were too shallow to be used as a source of drinking water.

Pesticide and nitrate concentrations in the study area are low relative to other agricultural areas of the Nation. Several authors have suggested that ground water in parts of the Upper Midwest is minimally contaminated because it is protected by the surficial glacial till or tile drains. These ideas are examined in light of the relations between concentration, well depth, and groundwater age in the study area.

Most of the shallow ground water is hydraulically connected to the land surface, based on the observations that 83 percent of waters from monitor wells were recharged after 1953, and 57 percent contained a pesticide or an elevated nitrate concentration. Fractures or sand-and-gravel stringers within the till are the probable pathways.

In some areas, deeper parts of the groundwater- flow system are also hydraulically connected to the land surface. Almost half the waters from wells 50 to 100 feet deep were recharged after 1953. Anthropogenic constituents were detected in samples from three domestic wells 60 to 121 feet deep, in areas where the till is relatively coarse-grained.

The hydrogeologic system has several geochemical characteristics conducive to transformations or sorption of nitrate or pesticides: (1) the till is clay-rich, has a high organic-carbon content, and contains an abundance of pyrite-rich shale fragments, (2) the ground water has low dissolved- oxygen concentrations, and (3) iron and manganese oxides and oxyhyroxides line the faces of fractures in the unsaturated zone.

Although the aquifer system appears be protected from contamination in some areas, the fact that the surficial till is heterogeneous and of variable thickness suggests that the protection is not uniform. The protection can be breached by fractures or sand-and-gravel stringers, which are apparent in core samples but not noted on domestic-well logs.

The data were processed using standard reduction formulas and parameters. Rock properties such as lithology, magnetic susceptibility and density also were measured at several locations. Rock property measurements will be helpful for future modeling and density inversion calculations from the gravity data. On both the Bouguer and isostatic gravity maps, a prominent, 13-km long (8 mi), approximately 1-km (0.62 mi) wide gradient with an amplitude of 7 mGal, down to the northeast, is interpreted as the gravity expression of the Rialto-Colton fault. The gravity gradient strikes in a northwest direction and runs from the San Jacinto fault zone at its south end to San Sevine Canyon at the foot of the San Gabriel mountains at its north end. The Rialto-Colton fault has experienced both right-lateral strike-slip and normal fault motion that has offset basement rocks; therefore it is interpreted as a major, through-going fault.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr00193","issn":"0094-9140","usgsCitation":"Anderson, M., Roberts, C.W., and Jachens, R.C., 2000, Principal facts for gravity stations in the vicinity of San Bernardino, Southern California: U.S. Geological Survey Open-File Report 2000-193, 32 p., https://doi.org/10.3133/ofr00193.","productDescription":"32 p.","costCenters":[],"links":[{"id":483871,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_26229.htm","linkFileType":{"id":5,"text":"html"}},{"id":281575,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2000/0193/"},{"id":51744,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0193/pdf/of00-193.pdf","text":"Report","linkFileType":{"id":1,"text":"pdf"}},{"id":155972,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0193/report-thumb.jpg"}],"country":"United States","state":"California","city":"San Bernardino","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -117.667,\n 34.25\n ],\n [\n -117.667,\n 33.94\n ],\n [\n -117,\n 33.94\n ],\n [\n -117,\n 34.25\n ],\n [\n -117.667,\n 34.25\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa7e4b07f02db6672ba","contributors":{"authors":[{"text":"Anderson, Megan L.","contributorId":69189,"corporation":false,"usgs":true,"family":"Anderson","given":"Megan L.","affiliations":[],"preferred":false,"id":188063,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Roberts, Carter W.","contributorId":45282,"corporation":false,"usgs":true,"family":"Roberts","given":"Carter","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":188062,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jachens, Robert C. jachens@usgs.gov","contributorId":1180,"corporation":false,"usgs":true,"family":"Jachens","given":"Robert","email":"jachens@usgs.gov","middleInitial":"C.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":188061,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ]}
