An Avian/Airport Study For Standiford Airport, Louisville, Kentucky: Results And Management Implications, Bernice U. Constantin, John K. Floyd

Wildlife Damage Management Conference

An avian/airport study was conducted by the U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Animal Damage Control (ADC) from 9 February 1989-18 March 1990 to evaluate near-term bird control needs at Standiford Field Airport (SDF), Louisville, Kentucky. Field surveys were performed on SDF and the Outer Loop Landfill (OLL) to gather data on both daily and seasonal trends in bird activity and effectiveness of management efforts employed by the OLL operator to control bird activity. Data for high-interest species groups were sorted according to site, time of day, weather, and month. Raptors were present at the airport …

Wildlife Damage Management: Policy And Professional Considerations, Harry E. Hodgdon

Wildlife Damage Management Conference

I am honored by the opportunity to be part of this conference and to participate with such a distinguished panel this morning.

Today I have been asked to address policy and professional considerations as they relate to wildlife damage management. As an advocate of professional wildlife management, I will share with you some of the problems and issues that confront, frustrate, and confound us; some sense of the problems that lie ahead; and some thoughts on what we need to do to ensure the wildlife profession remains relevant in the future.

The Effectiveness Of Soap In Preventing Deer Browsing, Michael J. Fargione, Milo E. Richmond

Wildlife Damage Management Conference

A series of bioassays was performed to evaluate the effectiveness of soap and soap components as deer (Odocoileus virginianus) repellents. Sweet-corn plots protected with tallow-based soap bars, nontallow bars, and those sprayed with the commercial repellent Hinder^®, experienced significantly reduced browsing compared with untreated plots. Damage to plots protected with tallow-based soap was less than damage to nontallow soap plots, while Hinder^®-treated plots had intermediate damage. In a second bioassay, 2 spray applications of soap were found to be as effective as soap bars in preventing browsing to native vegetation over a 126-day period. …

Incorporating Wildlife Damage Control Into A University Wildlife Management Curriculum, William G. Minser, Alex B. Coley

Wildlife Damage Management Conference

Most university wildlife programs that do not include wildlife damage control course offerings probably lack those courses for 2 main reasons: (1) most professors in those wildlife programs likely did not have formal training in wildlife damage control in their own degree programs and therefore may not have developed the skills nor the interest to teach this subject; and (2) universities may lack funding to hire new personnel to teach wildlife damage control.

Training Tomorrow's Specialists In Wildlife Damage Management, Robert H. Scmidt, Michael R. Conover, Raymond D. Dueser, Frederick F. Knowlton, Terry A. Messmer

Wildlife Damage Management Conference

In 1990, Utah State University (USU) established a U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Animal Damage Control (ADC)-funded center dedicated to research, education, and extension in wildlife damage management. USU's Program in Wildlife Damage Management is designed to increase appreciation for wildlife damage management among wildlife professionals, provide superior training for future practitioners of wildlife damage management through education and innovative research, and create better public understanding of the role of wildlife damage management in today's society.

Effectiveness Of Drc-1339 Baiting For Reducing Blackbird Damage To Sprouting Rice, James F. Glahn, E. Allen Wilson

Wildlife Damage Management Conference

Under a Special Local Needs (Section 24[c]) registration, the effectiveness of a 2% DRC-1339-treated brown rice baiting program to reduce bird damage to sprouting rice was evaluated during 1989 and 1990 at the Millers Lake blackbird roost, Evangeline Parish, Louisiana. After prebaiting with untreated rice, treated bait diluted with untreated rice at a ratio of 1:50 or 1:25 in 1989, and 1:10 in 1990, was applied at a rate of 112 kg/ha at sites strategically located under blackbird flightlines. Total treated bait mixtures applied to these sites were 3,487 kg in 1989 and 3,071 kg in 1990, of which an …

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

Wildlife Damage Management Conference

A questionnaire was developed and mailed to 340 farm operators within 8 km of Gettysburg National Military Park and Eisenhower National Historic Site, southcentral Pennsylvania. Names and addresses were derived from a list of farm operators and large-parcel landowners provided by the Agricultural Stabilization and Conservation Service of Adams County. A cover letter and accompanying questionnaire were mailed on 11 November 1987. After 3 weeks, nonrespondents were mailed a postcard reminding them of the survey. Those still not responding were mailed another questionnaire on 17 December. Our objectives were to determine the perceptions of farm operators concerning crop yields, and …

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

Wildlife Damage Management Conference

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 …

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

Wildlife Damage Management Conference

The Pennsylvania white-tailed deer (Odocoileus virginianus) herd has increased dramatically in the last several decades, despite greatly increased harvests. The high statewide deer density (11 + deer/km²) causes serious losses to agricultural crop production, forest regeneration, and diversity of forest flora and fauna. High deer numbers are associated with an excessive number of vehicle-deer accidents, and is implicated in the rapid increase in the incidence of Lyme disease in humans. Current 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 …

Efficacy And Methodology Of Urban Pigeon Control With Drc-1339, Keith M. Blanton, Bernice U. Constantin, Gerald L. Williams

Wildlife Damage Management Conference

During 1990 and 1991, feral pigeon (Columbia livia) baiting programs using compound DRC-1339 were conducted in 6 cities in Kentucky and Tennessee. U. S. Department of Agriculture, Animal and Plant Health Inspection Service, Animal Damage Control (ADC) personnel evaluated each problem site, selected bait sites, supervised prebaiting, mixed, and applied toxic bait In most cases, local personnel conducted the prebaiting and disposed of dead birds. Seven pigeon flocks containing 95-735 birds were reduced by up to 100% with 1 or 2 baitings with 0.37% DRC-1339-treated bait Most birds died at their roosting areas or on rooftops where they …

Synopsis Of A Course On The Principles Of Wildlife Damage Management, Michael R. Conover

Wildlife Damage Management Conference

Five courses were offered by Utah State University's Program in Wildlife Damage Management (WDM) in 1991: (1) Principles of WDM, (2) WDM Techniques, (3) Wildlife–Livestock Relationships, (4) WDM Policy, and (5) Urban Wildlife Management Principles of WDM was the introductory course in this series. It was an upper-division course; most students were in the Colleges of Agriculture and Natural Resources. In this paper, I provide a synopsis of this course hoping such information will be useful to other people designing a course on this topic.

Rather than using a textbook for Principles of WDM, students were required to read papers …

Survey Of Bird Damage To Blueberries In North America, Michael L. Avery, John W. Nelson, Marcia A. Cone

Wildlife Damage Management Conference

In this survey of 15 states and British Columbia, 84% of the 49 respondents considered bird damage to blueberries (Vaccinium sp.) to be serious or moderately serious. As in a similar 1972 survey, the European starling (Sturnus vulgaris), American robin (Turdus migratorius), and common grackle (Quiscalus quiscula) were listed as the most serious pest species. Most of the people surveyed who formerly used Mesurol® to control bird depredations felt that the severity of bird damage increased in 1989 when the registration for Mesurol® use on fruit lapsed. Based on the responses to …

Sheep And Goat Losses To Predators In The United States, Guy Connolly

Wildlife Damage Management Conference

This paper analyzes and compares 3 recent estimates of the value of sheep, lambs, and goats killed by predators in the United States. The estimates, by Pearson (1986a,b), the General Accounting Office (GAO 1990), and the National Agricultural Statistics Service (NASS 1991b), varied from $18 million to $59.7 million annually due to differences in scope, assumptions, data, and estimation methods of the 3 studies. Pearson's and NASS's estimates of the value of sheep and lambs lost to predators in 17 western states totaled $38.3 million and $18.3 million in 1984 and 1990, respectively. The difference between …

Perceived Risks Of Deer-Related Vehicle Accidents: Influence On Deer Population Preferences Of The Residents Of Tompkins County, New York, Richard C. Stedman, Rebecca J. Stout, Barbara A. Knuth, Daniel J. Decker

Wildlife Damage Management Conference

High populations of white-tailed deer (Odocoileus virginianus) in much of the eastern United States have increased the probability of deer-related vehicle accidents (DRVAs). These accidents are very costly in terms of vehicle repair and have the potential for serious physical injury to motorists. DRVAs are increasing rapidly in suburban areas, where deer may also cause other types of damage (i.e., to gardens or ornamental shrubs). In these suburban areas, wildlife professionals have limited deer management options. We hypothesized that the peoples' perception of the potential risk posed by ORV As interacts with the perceived benefits provided by deer, …

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

Wildlife Damage Management Conference

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 non wildlife majors), and Principles of Wildlife Management (a senior-level course required for wildlife majors).

Wildlife Damage Education At Auburn University, Nicholas R. Holler

Wildlife Damage Management Conference

Wildlife Damage Control is offered as a 3-hour course during winter quarter in alternate years at Auburn University. This course is taught simultaneously at the undergraduate and graduate levels. Prevention and Control of Wildlife Damage (R. Timm, ed.) 1983. Nebraska Cooperative Extension Service, University of Nebraska-Lincoln) is the course text, but numerous outside readings are provided on specific topic areas. Graduate students are given additional required reading material, must complete a term paper, and are given examinations requiring greater synthesis of ideas than do those administered to undergraduates. An optional weekend field trip, arranged in cooperation with United States Department …

Agency And Stakeholder Evaluations Of Citizen Participation In Deer Management Decisions: Implications For Damage Control, Rebecca J. Stout, Daniel J. Decker, Barbara A. Knuth

Wildlife Damage Management Conference

As in many states, wildlife managers and biologists in the New York State Department of Environmental Conservation, Bureau of Wildlife (BOW) set white-tailed deer (Odocoileus virginianus) population objectives in deer management units (DMUs). BOW has authority to regulate deer harvest through a deer management permit quota system. Decisions about regulating deer population levels have a direct impact on stakeholders concerned with the degree of damage to field and vegetable crops, orchards, nurseries, tree plantations, gardens, and ornamental shrubbery. Deer densities also affect economic and recreational benefits derived by other stakeholders. Developing management strategies that address these conflicting interests …

An Evaluation Of Roost Dispersal For Reducing Cormorant Activity On Catfish Ponds, Donald F. Mott, Keith J. Andrews, Gary A. Littauer

Wildlife Damage Management Conference

Pyrotechnics and helicopter flyovers were used to harass double-crested connorants (Phalacrocorax auritus) at 4 roost sites in the Delta region of Mississippi. Roosting connorants were easily dispersed from 3 of the 4 sites. Average numbers of cormorants observed at selected catfish (lctaluridae) ponds and day roosts near foraging areas also declined after harassment began.

Economics And Effectiveness Of Control Methods: Fact And Fiction, Rick D. Owens, Dennis Slate

Wildlife Damage Management Conference

Wildlife damage management decisions are often incorrectly viewed as being predicated solely upon economics. Although costs of wildlife damage and methods employed to reduce this damage are considerations in damage management decision-making, the selection and application of methods are also dependent upon environmental factors that include biological, physical, social, and legal influences. Professional decision-making involves an assessment of these factors on a case-by-case basis, to determine which methods and application strategies are environmentally cost-effective and therefore practical.

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

Wildlife Damage Management Conference

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 has occurred for over 50 years, and various strategies have been used to address these problems. Bear damage to agricultural crops and livestock became eligible for reimbursement by the state in 1939. The legislature terminated this program in 1980 in favor of a new program that placed greater emphasis on damage prevention than on compensation. Since 1984, WDNR has managed bear damage primarily through …

Evaluation Of A New Deer Repellent On Japanese Yews At Suburban Homesites, Roger W. Sayre, Milo E. Richmond

Wildlife Damage Management Conference

Jersey, an experimental deer repellent, was field tested against 2 commercial repellents on Japanese yews (Taxus cuspidata) near Ithaca, New York, during spring 1990. In Experiment 1, plots (n = 24) of 4 individually-potted yews were established, with 2 yews at each plot randomly treated with Jersey and 2 left as controls. Plots of 4 (1 x 4, n = 12) and 16 (4 x 4, n = 2) plants were used in Experiment 2, with individual plants being treated with Jersey, Hinder^R, or Big Game Repellent^R (BGR^R) or left as controls. …

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

Wildlife Damage Management Conference

The U.S. Department of Agriculture (USDA) and National Agricultural Statistics Service (NASS) 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 specifically …

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

Wildlife Damage Management Conference

The coyote (Canis latrans) population in Pennsylvania has grown in the last several decades to about 4,000. 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.

Conference Summary And A Look To The Future, James E. Miller

Wildlife Damage Management Conference

It is with mixed feelings that I agreed, somewhat reluctantly, to accept this challenge of trying to summarize the implications of this Fifth Eastern Wildlife Damage Control Conference. Even though it has been over 8 years ago, I still remember burning the midnight oil and working in the predawn hours on the last eve of the First Eastern Conference trying to prepare closing remarks for use by my former Deputy Administrator, Merrill L. "Pete" Petoskey. In fact, even though some of the guard has changed, at least one of the professionals who helped provide their insight as we prepared those …

Comparison Of Methods For Detecting Voles Under Apple Trees, Mark E. Tobin, Milo E. Richmond, Richard M. Engeman

Wildlife Damage Management Conference

We conducted a study in 2 heavily infested orchards in the mid-Hudson Valley of New York to evaluate methods for detecting the presence of meadow voles (MV, Microtus pennsylvanicus) and pine voles (PV, M. pinetorum) under apple trees. We quantified several possible signs indicating the presence of voles in each of the 4 quadrants under the canopy of each tree, and then set and monitored traps until capture success in the orchard declined to zero. There was no evidence that the 4 quadrants differed with respect to any of the variables examined. The apple slice index (ASI) was …

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

Wildlife Damage Management Conference

We conducted experiments with behavioral conditioning of white-tailed deer (Odocoileus virginianus) using vertical 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, …

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

Wildlife Damage Management Conference

Perception and reality. One and the same, or are they different? There are certainly a diversity of perceptions. Are there also multiple realities?

The Quabbin Reservation White-Tailed Deer Impact Management Plan: A Case History, James A. Parkhurst, Robert W. O'Connor

Wildlife Damage Management Conference

Quabbin Reservation, a 22,662-ha watershed management area located in west-central Massachusetts, is experiencing moderate to severe browsing pressure by white-tailed deer (Odocoileus virginianus) on much of the reservation's forested land. In many areas, park-like habitat exists where natural regeneration of the dominant mixed oak (Quercus spp.) forest has been severely repressed, or outright eliminated, due to repetitive browsing by deer. Understory composition is now dominated by patches of blueberry (Vaccinium angustifolium), huckleberry (Gaylussacia baccata), thick carpets of hay-scented fern (Dennstaedtia punctilobula), and grasses. Managers are concerned that as the forest ages …

Interactions Between People And Wildlife In Urbanizing Landscapes, John Hadidian

Wildlife Damage Management Conference

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 …

Public Involvement In Coyote Management Decisions, Robert A. Inslerman

Wildlife Damage Management Conference

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 …
