Investigation Of Optimum Sample Number And Timing For Determining Pollution Loads, T. S. Soerens, Marc A. Nelson

Arkansas Water Resources Center Technical Reports

In order to determine the impacts of non point source (NPS) pollution and to develop Total Maximum Daily Loads (Tr\tfDLs), accurate measurements of pollution loads in streams are critical. The objectives of this study were to accurately detemline pollutant loads at two sites by intensive storm sampling, to develop sub-sampling and other data analysis techniques, to detemline the effect of sample interval on load calculation accuracy, and to find the minimum sample interval required to determine storm loads at a required accuracy. The two stream sites used were a 1st order and a 3rd order stream in the Illinois River …

The Aquaculture Of Non-Endemic Species In Western Australia Silver Perch (Bidyanus Bidyanus), Tina Thorne, H. G. Brayford

Fisheries Management Papers

The development of commercial aquaculture of a non-endemic species such as silver perch raises a number of important issues relating to translocation. These include the potential of the introduced species to: impact on genetic diversity; introduce disease; and impact on - the natural environment; and - the biodiversity of native species. This Management Paper has been drafted in liaison with the Department of Environmental Protection in accordance with the principles of rish assessment, taking into account the above issues. It is considered that the implementation of this policy will protect the natural environment and native fish species. It will also …

The town of Yarmouth currently has a $30 million septic sludge treatment plant and transport lines in place. The vast majority of the dwellings and businesses in the Hyannis Park area are on septic systems that are viable and Title 5 compliant, regardless of age. Conventional, "non-failing" septic systems, however, were never intended to remove form their effluent nutrients such as nitrogen. These have become recognized as an environmental threat only as our understanding of the impacts of excess nutrients on ecosystems has increased in recent decades.

Western Rangeland Noxious Weeds: Collecting, Sharing And Using Information, U.S. Department Of Interior, U.S. Department Of Agriculture, Riley Memorial Foundation

All U.S. Government Documents (Utah Regional Depository)

Western rangeland weeds such as yellow starthistle, leafy spurge, Canada thistle and Russian knapweed are causing tremendous losses to agricultural industries, including both crop and livestock production, and to environmental resources on private lands. Concurrently, many public lands managed by federal agencies are being steadily invaded. As a result, these lands held in the public trust are experiencing reductions in commodity yields, recreational opportunities, biodiversity and ecosystem function.

Rejex-It® Bird Repellents - Mode Of Action, Peter F. Vogt

Wildlife Damage Management Conference Proceedings

Rejex-it® bird repellents are used to repel birds and reduce bird predation. Rejex-it® represents a long-needed, logical alternative to inhumane bird control methods such as poisoning and shooting. Its effectiveness as a nuisance bird repellant is based on a common, naturally-occurring, com lly recognized as safe" food and ponent of food that has been designated by the FDA as a "generafragrance additive. Methyl Anthranilate (MA), the active ingredient in Rejex-it® Bird Repellents, acts as a sensory repellent by irri tating the bird's taste buds, skin, and trigeminal chemoreceptors in the beaks, gizzards, eyes, and mucous membranes. Irritation occurs as a …

Spatial And Temporal Changes In Land Use And Land Cover From 1988 To 1992 In The Upper White River Watershed, H. D. Scott, J. M. Mckimmey

Arkansas Water Resources Center Technical Reports

Changes in Land Use and Land Cover (LULC) in the upper White River Watershed from 1988 to 1992 were analyzed and plotted using the geographic information system known as Geographic Resources Analyses Support System (GRASS). This portion of the White River Watershed includes two sub-basins the East Fork and the Middle Fork. In addition, LULC changes were determined for two smaller sub-basins, Shumate Creek and Cannon Creek, located in the East Fork of the White River. The sources and methods of interpretation of the 1988 and 1992 of data were different. Thus, there were variations in how certain portions of …

Ground Water In Northwest Arkansas: Minimizing Nutrient Contamination From Non-Point Sources In Karst Terrane, R. K. Davis, J. V. Brahana, J. S. Johnston

Arkansas Water Resources Center Technical Reports

The purpose of the project is to evaluate the effectiveness of Best Management Practices (BPMs) in preventing non-point source contamination of the ground-water resources in the karst terrane of northwestern Arkansas. Limestone and dolomite aquifers in the region are highly vulnerable to contamination. Ground-water studies performed in the region during the last two decades indicate degradation of these carbonate aquifers by nutrients and bacteria. The expeditious growth of the poultry industry during this period, in combination with the inordinate population growth of the region constitute a threat to the ground-water resources from both point sources and non-point sources of contamination. …

A Science-Based Initiative To Manage Double-Crested Cormorant Damage To Southern Aquaculture, James F. Glahn, Mark E. Tobin, Bradley F. Blackwell

United States Department of Agriculture Wildlife Services: Staff Publications

Aquaculture has expanded rapidly in the Southern United States during the past two decades, especially the cultivation of catfish, crawfish, and bait fish. These fish usually are cultivated on farms with extensive systems of large shallow ponds that are highly susceptible to predation by birds. Double-crested cormorants (Phalacrocorax auritus ), American white pelicans (Pelecanus erythrorhynchos ), wading birds (e.g., Ardea alba, Ardea herodius ), and scaup (Aythya spp. ) are among the birds most frequently implicated. Well-documented problems associated with cormorant predation on catfish farms have coincided with the increase of this industry and the rapid …

Usda-Aphis-Wildlife Services’ Involvement At Airports During Fy 1999 (Poster), Jessica Dewey

Bird Strike Committee-USA/Canada Joint Annual Meeting: 2nd (2000)

Birds and other wildlife are a serious problem at U.S. airports. Wildlife strikes cost U.S. civil aviation over $300 million per year, based on data from 1990-1998, and the number of reported bird strikes to civil aircraft has increased over 104% during that same time period. The increase in aircraft striking wildlife is due in part to the significant increase of various wildlife populations during the past 30 years. The United States Department of Agriculture, Animal and Plant Health Inspection Service, Wildlife Services (WS) program provides Federal assistance to airports in addressing wildlife hazards to aircraft. To comply with the …

Economic Analysis Of A Large Scale Oral Vaccination Program To Control Raccoon Rabies, Philip Kemere, Michael K. Liddel, Phylo Evangelou, Dennis Slate, Steven Osmek

Human Conflicts with Wildlife: 2002 Symposium

Since the late 1980s, results of oral vaccination trials in several states have provided growing evidence that this vaccination method may be effective for controlling the spread of rabies in raccoons (Procyon lotor). This study examines the economic feasibility of using oral vaccination on a larger scale than previous trials. We analyze the benefits and costs associated with a hypothetical barrier that would stretch from Lake Erie to the Gulf of Mexico, combining natural geographic features provided by the Appalachian Mountains with oral vaccination zones. The goal of this barrier would be to prevent the raccoon rabies variant …

Cormorant Depredation Losses And Their Prevention At Catfish Farms: Economic Considerations, James F. Glahn, Scott J. Werner, Terry Hanson, Carole R. Engle

Human Conflicts with Wildlife: 2002 Symposium

Although several piscivorous birds are involved in depredation conflicts with southern aquaculture, the double-crested cormorant causes some of the most widespread and significant problems to catfish, the dominant industry. Unlike other agriculture commodities, catfish losses due to predation cannot be directly measured, so we review several approaches taken to estimate these losses. Although these approaches are valid for predicting the costs of simply replacing these fish at the time of predation, they have been criticized because they failed to consider the functional relationships between predation and output parameters at harvest. Recent controlled experiments are reviewed that confirm previous estimates of …

Fundamentals Of Economic Principles And Wildlife Management, Peter W. Schuhmann, Kurt A. Schwabe

Human Conflicts with Wildlife: 2002 Symposium

This paper presents an overview of the economic fundamentals involved in wildlife management, with special consideration for cases involving harmful wildlife-human interactions. The process of benefit-cost analysis is used as a unifying platform for incorporating both theoretical and empirical issues. Topics such as external market effects and public goods are detailed in order to give the reader a theoretical foundation for understanding the economic perspective on the problems associated with defining and attaining optimally managed wildlife populations. To these principles we add practical considerations for measuring the costs and benefits associated with wildlife populations. Different categories of wildlife values, such …

Damage Abatement And Compensation Programs As Incentives For Wildlife Management On Private Land, Jonathan K. Yoder

Human Conflicts with Wildlife: 2002 Symposium

Public damage abatement and compensation programs may be used to alter private incentives for damage abatement and habitat provision. A model is developed that explains the economic logic behind prevalent characteristics of public wildlife damage programs. The model is supported with an examination of a broad cross-section of wildlife agency policy and law. The model can be used by wildlife managers and policy makers as a conceptual framework for understanding the incentive effects of compensation and abatement policy.

The Endangered Species Act And Private Landowner Incentives, Jeffrey A. Michael

Human Conflicts with Wildlife: 2002 Symposium

While intended to increase the habitat available to endangered species, the restrictions of the Endangered Species Act (ESA) increase the costs of harboring an endangered species to private landowners and create incentives for private landowners to reduce habitat. This paper illustrates the incentive for habitat destruction with a simple model of private land use under the ESA, and uses it to predict the effects of changes in policy or biological conditions on private landowner incentives. Many anecdotal accounts and recent empirical research support the predictions of the model. Because of the ESA’s perverse incentives, many have proposed replacing the punitive …

Economic Considerations Of Damage Assessment, Richard M. Engeman

Human Conflicts with Wildlife: 2002 Symposium

Cost-effectiveness is the fundamental economic test of any damage control or damage mitigation strategy, and damage assessment is the essential component for determination of cost-effectiveness. However, there are many potential costs associated with making damage assessments. The sampling and measurement required to produce a damage assessment have associated effort and costs, but even greater costs can be incurred due to inappropriate management decisions resulting from inaccurate damage assessments. Other costs can result from using an assessment method that is unsuited to management objectives, or by misinterpreting or not understanding the relationship between observed damage and actual losses. The concepts of …

Impacts Of House Mice On Crops In Australia: Costs And Damage, Peter R. Brown, Grant R. Singleton

Human Conflicts with Wildlife: 2002 Symposium

Rodents cause serious losses to crops in many different parts of the world. The house mouse (Mus domesticus, Schwarz and Schwarz 1943) is a serious pest to agriculture in Australia. The impacts of house mouse damage to crops in Australia were examined. Plagues of mice (> 1,000 mice/ha) cause enormous economic and social stress to rural communities in Australia. The mouse plague in 1993/94 caused about US$60 million in damage to crops, intensive livestock industries, and rural communities. The impact of mouse plagues is generally well understood, but there is a dearth of knowledge about the relationship between …
