A Regional Study Of Ground-Water Quality In Barry County, Michigan, Margene K. Brewer

Masters Theses

A regional study of ground-water quality in Barry County, Michigan was conducted using a computerized database from the Science for Citizens Center at Western Michigan University in Kalamazoo, Michigan. The database, initiated by the Michigan Groundwater Survey, consists of residential well logs and chemical analyses of samples collected from residential wells by the Barry County Health Department. Qualitative and statistical analyses of the data indicate that the glacial drift aquifer is recharging the bedrock aquifer throughout most of the county. Groundwater quality appears to be controlled mainly by the open-system dissolution of carbonate minerals. The water chemistry is also influenced …

Effects Of Capillarity On Dnapl Thickness In Wells And In Adjacent Sands, Timothy V. Adams

Masters Theses

Physical model experiments were used to investigate the behavior of dense non-aqueous phase liquids (DNAPLs) in various geologic media.

The objectives of the laboratory investigations were to (a) compare DNAPL thickness in wells to thickness in adjacent sands, (b) observe and interpret dyed DNAPL migration in unsaturated and saturated sands, and (c) study DNAPLs' effects on clay layers.

Two cylindrical glass columns fitted with various well screens were filled with sand, clay layers, water, and dyed DNAPLs in four experiments. Columns were packed with fine or coarse sand and clay layers. Coarse hydrophobic sand was also used.

At equilibrium, DNAPL …

The Effects Of Urbanization On A Portion Of The Portage Creek Watershed: A Case Study On Surface Water And Groundwater Quality, Susan E. Rezek

Masters Theses

The surface water and groundwater quality in the study area of the Portage Creek watershed was analyzed to determine the possible effects of urbanization. Dry weather and wet weather surface water and groundwater samples were collected from June 1986 to November 1986 at selected stations in the watershed.

Water samples were analyzed for 26 inorganic and organic parameters. Most concentrations were below analytic method detection limits. The analytical data indicate that sodium and chloride are the principal contaminants resulting from urbanization. The probable source of the contamination is deicing salt applied to the City of Portage, Michigan streets.

Overall, the …

Lines To Selectively Repel House Sparrows From Backyard Feeders, Kimberly K. Kessler, Ron J. Johnson, Kent M. Eskridge

Great Plains Wildlife Damage Control Workshop Proceedings

House sparrow {Passer domesti-cus) flocks are often disliked at backyard feeding stations because they use space and food intended for other species. Monofila-ment lines, spaced 30 or 60 cm apart, have been shown to repel house sparrows from certain feeders, but responses of many back-yard bird species to lines are unknown. Three experiments were conducted at 2 sites during winter and repeated in spring using feeders with and without lines. Four pole-mounted feeders were used at each site, with an 80-cm-diameter tray on the ground below each feeder. Two feeders at each site were controls (C) without lines and 2 …

Perceptions About Crop Yields And Losses To White-Tailed Deer On Farms Surrounding Gettysburg National Military Park, Gary M. Vecellio, Gerald L. Storm, Richard H. Yahner

Eastern Wildlife Damage Control Conference: 5th (1991)

Our objectives were to determine the perceptions of farm operators concerning crop yields, and effects of white-tailed deer (Odocoileus virginianus) on crop lands surrounding Gettysburg Park. The survey consisted of 4 multiple-choice and 5 fill-in questions. Questions were developed to gauge land area planted and harvested by crop type, relative severity of impacts to crops by 8 wildlife species, and amount of crop production lost to deer. Questions were also included to quantify perceptions on the 5-year trend in deer numbers, respondent's wishes for future deer numbers, and the number and type of people permitted to hunt deer …

Use Of Livestock Protection Collars To Protect Sheep And Goats, Murray T. Walton

Eastern Wildlife Damage Control Conference: 5th (1991)

The sodium monofluoroacetate (Compound 1080) Livestock Protection Collar is selective for individual predators attacking the throat of sheep or goats and is especially useful in taking coyotes (Canis latrans). However, fears of secondary and nontarget poisonings have resulted in restrictions on their use. They are registered for use in the United States only to kill coyotes. To satisfy U.S. Environmental Protection Agency requirements, the Texas Department of Agriculture provides training and testing for certifying collar applicators, and has monitored collar use from 1988 through 1990. During this period, 59 licensed applicators, 6 collar pools, and the Texas Animal …

Regulating Air Toxics In Rhode Island: Policy Vs. Technical Decisions, Julie A. Roque

RISK: Health, Safety & Environment (1990-2002)

Dr. Roqu6 recounts her work as a doctoral candidate at Brown in developing standards for the regulation of airborne carcinogens. Based in part on this experience, she argues that care needs be taken lest those who regulate Risk bury key policy decisions within a mass of often irrelevant technical details.

Minimizing Deer Damage To Forest Vegetation Through Aggressive Deer Population Management, Raymond J. Winchcombe

Eastern Wildlife Damage Control Conference: 5th (1991)

Controlled hunts were used annually between 1976-90 on the Mary Flagler Cary Arboretum in southeastern New York to control deer (Odocoileus virginianus) population expansion and prevent over-browsing of forested and landscaped areas. The primary objective of the hunts was to remove sufficient numbers of adult female deer each year to stabilize herd growth and minimize browsing pressure. Hunters had to register early, attend a preseason meeting, pass a shooting proficiency test, apply for a deer management permit, and pay a fee. Spring browse-use surveys, using several tree species as an index to browsing pressure, showed low use through …

Bear Damage To Agriculture In Wisconsin, Laine R. Stowell, Robert C. Willging

Eastern Wildlife Damage Control Conference: 5th (1991)

Black bear (Ursus americanus) are common in northern Wisconsin. The Wisconsin Department of Natural Resources (WDNR) has established a population goal of 6,000 bears across 46,361 km2 of bear range. Bear damage to agriculture occurred for over 50 years, and various strategies have been used to address these problems. Bear damage to agricultural c and livestock became eligible for reimbursement by the state in 1939. The legislature terminated this program in 1980 in fate of a new program that placed greater emphasis on damage prevention than on compensation. Since 1984, WDNR has bear damage primarily through abatement practices …

The Need And Difficulty Of Bringing The Pennsylvania Deer Herd Under Control, Gary W. Witmer, David S. Decalesta

Eastern Wildlife Damage Control Conference: 5th (1991)

The Pennsylvania white-tailed deer (Odocoileus virginianus)herd has increased dramatically in the last several years despite greatly increased harvests. The high statewide deer density (11+ deer/kmz) causes serious losses to agricultural production, forest regeneration, and diversity of forest flora and fauna. High deer numbers are associated with an exceptional number of vehicle-deer accidents, and is implicated in the rapid increase in the incidence of Lyme disease in humans. Countless efforts to reduce deer densities locally and statewide (extended antlerless harvest seasons and special farm hunts) are not solving the damage problem. Other solutions should be considered, such as increasing …

Status Of Coyotes And Coyote Depredations In Pennsylvania, Gary W. Witmer, Arnold Hayden

Eastern Wildlife Damage Control Conference: 5th (1991)

The coyote (Canis latrans) population in Pennsylvania has grown in the last several decades to about4,000. It continues to grow, despite a known annual harvest of more than 850 animals. There is a growing concern about the effects of coyotes on game and livestock populations. We discuss known and potential coyote-human conflicts in Pennsylvania and propose a program of depredation prevention and control. To be successful, the program requires cooperation, funding, research, educational materials, and training workshops.

Agricultural Producers' Estimates Of Wildlife Causing Damage Eastern States, Alice P. Wywialowski, Robert H. Beach

Eastern Wildlife Damage Control Conference: 5th (1991)

The U. S. Department of Agriculture (USDA) and National Agricultural Statistics Service (MASS) conducted a nationwide survey of agricultural producers to determine what proportion of producers were sustaining losses caused by wildlife and which wildlife species were believed to be responsible for the damage. The survey was conducted in August 1989 for the USDA, Animal and Plant Health Inspection Service, Animal Damage Control (ADC). Results are based on useable responses received from 5,085 farmers in the eastern United States. The results presented here may differ from a previous press release by NASS because losses and animals causing losses were determined …

Citizen Task Force On Deer Management, Mike Hall

Eastern Wildlife Damage Control Conference: 5th (1991)

In spring 1990, as part of an intensified effort to involve the public in wildlife management decisions, the New York State Department of Environmental Conservation (DEC) and Cornell Cooperative Extension (CCE) implemented a new public input program. Citizen task forces were organized in 15 deer (Odocoileus virginianus) management units (DMUs) across the state. The task force purpose was to choose a desired deer population level for their particular DMU.

DEC and CCE designed task forces to include a broad range of interests, in order to balance the viewpoints of various groups affected by deer. CCE agents and DEC …

Wildlife Damage Education And College Curricula, James Caslick

Eastern Wildlife Damage Control Conference: 5th (1991)

University students, particularly those enrolled in natural resources programs, make up one of the smallest, yet potentially most important and influential audiences for wildlife damage professionals. Considering that these students will be tomorrow's natural resources technicians, biologists, and administrators, I feel that it is critical that we provide them factual information about wildlife damage to increase their awareness of potential problems and solutions, and increase their ability to make well-informed decisions.

An important aspect of education is accurate audience identification and association. This is not an easy task, however, as today's audience is collectively a moving target. Once primarily rural …

Perceptions And Realities: When Does 2 + 2 = 5?, Robert M. Timm

Eastern Wildlife Damage Control Conference: 5th (1991)

The theme of this conference, "Human and Wildlife Interactions: Public Perceptions and Management Realities," suggests to me that the reality of what wildlife managers do is often affected by the public's perception of the problem. In considering animal damage, there's the question of which solutions the public fords appropriate and acceptable. Attitudes and perceptions nowadays, whether correct or based on misinformation, are often translated into policy and law. "Management realities"- why can't we just go ahead and solve the problem the way we want to? After all, we're the scientists and wildlife managers; we know the problem better than anyone. …

Interactions Between People And Wildlife In Urbanizing Landscapes, John Hadidian

Eastern Wildlife Damage Control Conference: 5th (1991)

In little more than 100 years, America has been transformed from a rural to an urban society in which 8 out of every 10 people live in cities or associated metropolitan areas. This change has affected the way that people interact with wildlife and has introduced new and unique situations in which human-wildlife conflicts arise and must be dealt with. Most urban wildlife problems occur in and around primary residences or nodes (e.g., airports, golf courses, lake fronts) and involve only a few species. This relationship may change as urban landscapes mature or expand through restoration efforts, or as more …

Effects Of Chronological Deer Damage On Corn Yields, Scott E. Hygnstrom, Jan R. Hygnstrom, Kurt C. Vercauteren, Nancy S. Foster, Susan B. Lembezeder, Dale J. Hafer

Eastern Wildlife Damage Control Conference: 5th (1991)

To examine the relationship between the timing of deer (Odocoileus virginianus) damage and subsequent yields of field corn, we conducted 2 studies in 2 cornfields in eastern Nebraska during 1989 and 1991.

New York State Department Of Environmental Conservation, Robert A. Inslerman

Eastern Wildlife Damage Control Conference: 5th (1991)

In 1990, the Legislature passed a bill that would have allowed year-round hunting of coyotes (Canis latrans) in New York's Northern Zone, as opposed to the current system of open and closed hunting seasons established annually by Department of Environmental Conservation (DEC) regulation. The bill generated such controversy that it was withdrawn pending a study by DEC. The objectives of the study were to: (1) assess the role of the coyote in northern New York in relation to people, wildlife, and livestock; (2) provide adequate opportunity for citizens to express their opinions concerning coyotes; and (3) prepare a …

United Conservation Alliance, Laurence R. Jahn

Eastern Wildlife Damage Control Conference: 5th (1991)

We gather here and reflect on successes in wildlife conservation, restoration, and management; and make plans for more beneficial actions. Significant achievements have been madein public education and wildlife management, as shown by increases in some wildlife populations. But a continuing pressing challenge involves responding to some wildlife population declines, as well as wildlife damage and nuisance situations, as the human population increases and dominates the landscape.

As you well know, management successes involve imagination and dedication of people, such as those gathered here. Your efforts play an important role in helping to manage wildlife, and provide associated outdoor recreational …

Effectiveness Of A Vertical 3-Wire Electric Fence Modified With Attractants Or Repellents As A Deer Exclosure, Don M. Jordan Jr., Milo E. Richmond

Eastern Wildlife Damage Control Conference: 5th (1991)

We conducted experiments with behavioral conditioning of white-tailed deer (Odocoileus virginianus) using verb 3-wire, electrified fencing modified with either an attractant or a repellent in order to test the idea that an attractant or repellent coupled with an electric shock, would be a more effective deterrent than a random shock or no shock at all. Exclosures measuring 6 x 6 m with 3 wires at heights of 50, 100, and 150 cm were established at 2 study sites in Tompkins County, New York. Each site contained 4 exclosures which were either nonelectrified (control), electrified, electrified with an attractant, …

Strategies To Control Rodent Damage In Sugar Bushes: An Update, Alan May, John Austin, Dennis Slate

Eastern Wildlife Damage Control Conference: 5th (1991)

Efficacy trials using zinc phosphide (ZP) steam-rolled oats (2% a.i., EPA Reg. No. 56228-5), and cholecalciferol mixed (CHOL) grain bait (.075% a.i., EPA Reg. No. 12455-57), were conducted during summer 1990 to compare their effectiveness in controlling rodent damage to plastic tubing systems used to collect sap from sugar maples (Acer saccharum) in Vermont. A 24(c) Special Local Needs registration for ZP to control rodent damage has existed in Vermont since the 1960s. However, no formal efficacy trials have been conducted for this specific use of ZP, and the previous supplemental label did not include instructions for prebaiting …

Wildlife Damage Education At West Virginia University, Edwin D. Michael

Eastern Wildlife Damage Control Conference: 5th (1991)

West Virginia University has offered a formal wildlife damage course in each of the last 2 years (1990 and 1991). Prior to offering the formal course in 1990, the topic of wildlife damage was presented as one section of 2 different courses: Introduction to Wildlife Management (for nonwildlife majors), and Principles of Wildlife Management (a senior-level course required for wildlife majors).

The current wildlife damage course involves 2 1-hour lectures per week and students receive 2 semester credit hours upon completion. Two class periods per semester are devoted to field exercises, involving demonstration of damage control equipment and investigation of …
