Comprehensive Management Of Commensal Bats, Stephen C. Frantz, Brian R. Laniewicz Oct 2000

Comprehensive Management Of Commensal Bats, Stephen C. Frantz, Brian R. Laniewicz

Wildlife Damage Management Conference

This paper reviews the basic concepts behind a comprehensive management approach to managing commensal species, and then considers how this approach is applied to bats that live within and about the built environment. Management activities should take into consideration the whole environment in which the target species is active, including the periodic changes that occur within that environment. Comprehensive management includes a clear understanding of: the biology, behavior and ecology of the species to be managed; the environment in which that species is active (especially harborage location); and the appropriate intervention methods used to manage such species. Interventions fall under …


Perceptions Of White-Tailed Deer Abundance And Management Among Hunters And Landowners In Illinois, Craig A. Miller, Paul Shelton Oct 2000

Perceptions Of White-Tailed Deer Abundance And Management Among Hunters And Landowners In Illinois, Craig A. Miller, Paul Shelton

Wildlife Damage Management Conference

State wildlife agencies often find themselves between hunters and landowners in managing white-tailed deer. During 1999 the Illinois Department of Natural Resources (IDNR) restricted archery deer harvest in a 5-county region of East-central Illinois to antlered deer only during the first month of the season. Restrictions were due to declining deer populations and increased archery harvest in the 5-county zone. Hunters in adjacent Shelby County claimed they were seeing fewer deer and lobbied both the IDNR and state legislators for inclusion in the restricted zone during the fall 2000 hunting season. We conducted a telephone survey of resident archery deer …


Suburban Goose Management: Insights From New York State, Bryan L. Swift Oct 2000

Suburban Goose Management: Insights From New York State, Bryan L. Swift

Wildlife Damage Management Conference

New York State Department of Environmental Conservation (DEC) conducted studies in suburban Rockland County, New York during 1993-2000 to help local officials develop strategies to alleviate conflicts associated with local-nesting or "resident" Canada geese (Branta canadensis). Annual counts indicated a relatively stable population of approximately 2,500-3,000 resident geese in the county, far fewer than anecdotal reports suggested. Counts tended to increase in towns where there was little or no goose management, whereas numbers declined in towns with active goose management efforts (i.e., egg-addling, capture and removal, or use of border collies). Egg-addling programs did not result in immediate reduction of …


Evaluation Of Moderate And Low-Powered Lasers For Dispersing Double-Crested Cormorants From Their Night Roosts, James F. Glahn, Greg Ellis, Paul Fioranelli, Brian S. Dorr Oct 2000

Evaluation Of Moderate And Low-Powered Lasers For Dispersing Double-Crested Cormorants From Their Night Roosts, James F. Glahn, Greg Ellis, Paul Fioranelli, Brian S. Dorr

Wildlife Damage Management Conference

The double-crested cormorant (Phalacrocorax auritus) is the primary avian predator on the southern catfish industry, estimated to cause $5 million in damage per year. To date, the most effective strategy for alleviating cormorant depredations in areas of intensive catfish production is coordinated dispersal of cormorant night roosts with pyrotechnics. Many of these night roosts are located in waterfowl refuges or wetland habitat leased for waterfowl hunting. Thus, there is an increasing concern about the effects of cormorant harassment efforts on waterfowl and other wildlife inhabiting these sites in cypress-swamp habitat. To address the need for a roost harassment device that …


Special Resident Canada Goose Hunting Seasons In Pennsylvania - Management Implications For Controlling Resident Canada Geese, John P. Dunn, Kevin J. Jacobs Oct 2000

Special Resident Canada Goose Hunting Seasons In Pennsylvania - Management Implications For Controlling Resident Canada Geese, John P. Dunn, Kevin J. Jacobs

Wildlife Damage Management Conference

Special hunting seasons were first implemented in 1992 to help reduce the growth rate of Pennsylvania's rapidly expanding resident Canada goose (Branta canadensis) population. Special seasons timed to occur before and after fall migration were successful in harvesting resident and not migrant Canada geese. Since 1992, September and late season hunting opportunities have been gradually expanded to include the entire state. The special season harvest of resident Canada geese has increased from about 13,000 birds in 1992 to over 68,000 in 1999. Special hunting seasons now account for over 80% of the entire Canada goose kill in Pennsylvania. Despite the …

Variation Of White-Tailed Deer Home Ranges In Fragmented Urban Habitats Around Chicago, Illinois, Brian P. Piccolo, Karmen M. Hollis, Richard E. Warner, Timothy R. Van Deelen, Dwayne R. Etter, Chris Anchor Oct 2000

Variation Of White-Tailed Deer Home Ranges In Fragmented Urban Habitats Around Chicago, Illinois, Brian P. Piccolo, Karmen M. Hollis, Richard E. Warner, Timothy R. Van Deelen, Dwayne R. Etter, Chris Anchor

Wildlife Damage Management Conference

Behavior of white-tailed deer (Odocoileus virginianus) has been studied extensively in refuges and agricultural regions, although little research has focused on deer in urban environments. Dramatic urbanization and development fragments habitat available for wildlife species and deer densities often exceed ecosystem carrying capacity in remnant natural areas. This may impact deer social behavior and spatial home range patterns. We radio-marked 21 female white-tailed deer in the Des Plaines and Palos Forest Preserves near Chicago, Illinois to study spatial use of deer relative to conditions in urban forest preserves. Telemetry locations were collected once per week and included both day and …

Is Translocation Effective For Reducing Raptor Strikes?, Laurence M. Schafer

Wildlife Damage Management Conference

From March 1996 to 31 December 1999, Wildlife Services (WS) personnel trapped and relocated 316 raptors from one of the nation's busiest airports: 147 American kestrels (Falco sparverius), 158 red-tailed hawks (Buteo jamaicensis), 5 rough-legged hawks (Buteo lagopus), 4 peregrine falcons (Falco peregrinus), 1 northern harrier (Circus cyaneus), and 1 eastern screech owl (Otus asio). On 1 January 1999, the Federal Aviation Administration sponsored a 2-year study, in conjunction with the National Wildlife Research Center and WS-Illinois, to evaluate the efficacy of raptor relocation at the airport. This study began in September 1999 and (1) monitors the post release activity …


Behavioral Observations And Physiological Implications For White-Tailed Deer Treated With Two Different Immunocontraceptives, Gary J. Killian, Lowell A. Miller Oct 2000

Behavioral Observations And Physiological Implications For White-Tailed Deer Treated With Two Different Immunocontraceptives, Gary J. Killian, Lowell A. Miller

Wildlife Damage Management Conference

The results of a 6-year behavioral study of white-tailed deer (Odocoileus Viginianus) treated with two immunocontraceptive vaccines, porcine zona pellucida (PZP) and gonadotropin releasing hormone (GnRH) are summarized. Does were immunized late summer and early fall. In November, does were exposed to bucks and observations were made 2-3 times daily for one half hour through the end of February. Does were considered to be in estrus when they were the object of intensive sexual interest by the buck. Compared to controls, PZP-treated does had a significantly lower fawning rate and an increase in the average number of estrous cycles observed …

Bada Bang, Bada Boom: Dispersal Of Fall Migrating Cormorants To Protect Sportfish On Oneida Lake, New York, Richard B. Chipman, Milo Richmond, Justin T. Gansowski, Ken J. Preusser, Douglas L. Stang, Jeremy Coleman, Dennis Slate

Wildlife Damage Management Conference

The interior population of double-crested cormorants (Phalacrocorax auritus) continues to increase. As a result, conflicts between human interests and cormorants have intensified. The impacts of nesting, roosting, and migrating cormorants include predation at aquaculture facilities, interspecific competition with rare species including common terns (Sterna hirundo), and impacts to private property. In addition, heightened public and scientific debate regarding cormorant impacts on sportfish has accelerated the need for effective, socially acceptable methods for managing local conflicts. In 1998 and 1999, USDA, APHIS, Wildlife Services; the New York State Department of Environmental Conservation; and USGS, New York Fish and Wildlife Research Cooperative …


The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter Oct 2000

The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter

Wildlife Damage Management Conference

Airports attract large numbers of wildlife primarily because they offer immense tracts of foraging and nesting habitats free from the threat of predation. Border collies can serve as an effective means of wildlife control in these environments by introducing a predator into the ecosystem. Many wildlife dispersal methods seek to imitate predators or the effect of predators and become increasingly ineffective as wildlife habituate to the stimuli. However, border collies are true predators, representing an actual, not perceived, threat to wildlife thereby eliminating the problems of habituation. Six airports and military bases have initiated use of border collies at their …

Turkey Damage Survey: A Wildlife Success Story Becoming Another Wildlife Damage Problem, James E. Miller, Brain C. Tefft, Robert E. Eriksen, Mike Gregonis Oct 2000

Turkey Damage Survey: A Wildlife Success Story Becoming Another Wildlife Damage Problem, James E. Miller, Brain C. Tefft, Robert E. Eriksen, Mike Gregonis

Wildlife Damage Management Conference Proceedings

Wild turkey (Meleagris gallopavo) populations have been restored and enhanced through introductions and reintroductions in 49 of the 50 states to huntable populations within the last 30 years. Populations are presently estimated to exceed 4 million birds within the United States. In many states, wild turkey habitat includes woodlots interspersed with agricultural lands, and some of the highest known population densities of wild turkeys are found in such areas. This paper will report on existing research, examining perceived versus actual damage caused by wild turkeys. It will also provide information based on a recent survey of biologists from the State …


Seven Years Of White-Tailed Deer Immunocontraceptive Research At Penn State University: A Comparison Of Two Vaccines , Lowell A. Miller, Gary J. Killian Oct 2000

Seven Years Of White-Tailed Deer Immunocontraceptive Research At Penn State University: A Comparison Of Two Vaccines , Lowell A. Miller, Gary J. Killian

Wildlife Damage Management Conference Proceedings

PZP and GnRH immunocontraceptive vaccines were each tested in white-tailed deer (Odocoileus virginianus). Vaccination with PZP produced reversible infertility lasting 1 to 4 years. The first two years of active immunization resulted in an 89% reduction in fawning. Reduction in fawning for the 7-year study containing 4 years of no boosting was 72%. PZP immunization resulted in multi-estrus behavior, with contracepted deer returning to estrus up to 7 times. A five year study of GnRH immunization was conducted in both male and female deer. Treatment of does led to reduced fawning rates, reduced estrus behavior and reduced concentrations of progesterone. …

What Will The Disease Issues Of The Future Be?, Robert G. Mclean Oct 2000

What Will The Disease Issues Of The Future Be?, Robert G. Mclean

Wildlife Damage Management Conference Proceedings

The major categories of diseases of the future involving wildlife are zoonotic diseases of public health importance, domestic animal diseases of economic importance, and wildlife diseases and health of wildlife importance. The existing patterns of these diseases include exotic, introduced diseases (West Nile virus - WNV), emerging diseases (Lyme disease), re-emerging diseases (animal rabies), and continuing diseases (leptospirosis). Some significant emerging public health diseases are WNV, hantavirus, Lyme disease, hemorrhagic E. coli 0157:H7, and antibiotic resistant bacteria. Emerging domestic animal diseases also include WNV, E. coli 0157:H7, salmonella enterica, and spongiform encephalopathies. Whereas, emerging wildlife diseases are WNV, particularly in …

Aversive And Disruptive Stimulus Applications For Managing Predation, John A. Shivik, Daniel J. Martin Oct 2000

Aversive And Disruptive Stimulus Applications For Managing Predation, John A. Shivik, Daniel J. Martin

Wildlife Damage Management Conference Proceedings

The range expansion and reintroduction of mammalian predators (e.g., wolves, coyotes and bears) coupled with growing disfavor for traditional tools of wildlife management creates an immediate need for alternative, non-lethal, but effective techniques for managing predation on livestock. Scientists at the National Wildlife Research Center are using advanced technology and animal behavior concepts (e.g., aversive and disruptive stimuli) to develop new tools for the prevention of damage by large mammalian predators, and this paper is a review of our pilot studies investigating these techniques. Recently tested tools include behavior contingent disruptive stimulus devices for wolves and coyotes. Experiments indicate the …


Coding Spreadsheets For Intervention Decisions In Wildlife Damage Management, Ray T. Sterner, H. Nicole Lorimer Oct 2000

Coding Spreadsheets For Intervention Decisions In Wildlife Damage Management, Ray T. Sterner, H. Nicole Lorimer

Wildlife Damage Management Conference Proceedings

Sterner (In press) described the use of a priori, theoretical analyses of crop/resource savings and benefit:cost ratios as a way of making intervention decisions in wildlife damage management. Iterative (1-variable-changed-at-a-time) calculations of these economic indices were computed for the use of zinc phosphide baits to control vole {Microtus spp.) populations in alfalfa (Medicago sativa). Results showed that indices displayed transitive effects — greater net savings and benefit:cost ratios were related to larger field-size, crop-damage and bait-effectiveness variables, but smaller bait-application fees. Ratios varied between 0.40 and 6.45, with -5-10% vole-caused damage required to produce returns on investments equal to the …


Community Bat Management, Jerry D. Hassinger, Calvin M. Butchkoski, Harold S. Korber Oct 2000

Community Bat Management, Jerry D. Hassinger, Calvin M. Butchkoski, Harold S. Korber

Wildlife Damage Management Conference Proceedings

When a house bat colony (primarily Myotis lucifugus) is excluded from a traditional maternity roost, surviving bats add to nearby roosts or access new roosts in other buildings. To prevent this and the potential for attendant nuisance, and to conserve bats, the Pennsylvania Game Commission recommends using one or more bat boxes to attract the displaced colony. The "standard-sized" bat box used in Pennsylvania will house up to 250 little brown bats. This reactive technique has proved useful for managing single, small colonies (< 1,000 bats) in rural areas. We are, however, trying a different, proactive technique to manage large colonies or multiple colonies in a community. Newport, PA, for example, has multiple colonies in buildings within 200 meters of riparian habitat along the Juniata River. Over 7,000 bats were counted exiting a single building. To begin the process of managing these bats, the high school conservation club and town leaders were engaged and presented information about the value of bats. Programs were also presented to a school assembly and to the community. As a result, the conservation club was provided with a site at the community's water treatment plant to erect a bat condo. This site is within 1 km of at least 2 large bat colonies in old buildings. The condo is a 2.4 m square box on posts. It's 2.4 m tall with its bottom 3 m above the ground. Inside, 80 sheets of plywood provide roosting crevices for at least 2,500 bats. Supervised by the Wildlife Diversity Section of the Game Commission, the condo was built in late spring, 1999. A chain-link fence helps protect it from vandalism.


A Private Lands Approach To Controlling New Jersey's Deer Population, David Drake Oct 2000

A Private Lands Approach To Controlling New Jersey's Deer Population, David Drake

Wildlife Damage Management Conference Proceedings

In New Jersey, annual losses from white-tailed deer (Odocoileus virginianus) depredation to agricultural crops have been estimated as high as $10 million. Additional problems caused by the state's overabundance of deer include increasing vehicle/deer collisions, possible human health concerns regarding increasing incidences of Lyme disease, and a loss of flora and fauna diversity. In an effort to reduce deer numbers and minimize damage, both non-lethal and lethal management practices have been used with limited success. Hunter access to private lands remains the biggest impediment to effective deer management in New Jersey. I propose an incentive-based program to increase lease and …


Efforts To Enhance Stakeholder Communications In North Carolina's Wildlife Damage Control Agent System, Peter T. Bromley, Carl W. Betsill Oct 2000

Efforts To Enhance Stakeholder Communications In North Carolina's Wildlife Damage Control Agent System, Peter T. Bromley, Carl W. Betsill

Wildlife Damage Management Conference Proceedings

In 1995, North Carolina Wildlife Resources Commission (NCWRC) established policy and rules for handling of nuisance wildlife by Wildlife Damage Control Agents (WDCA). The policy required a one-day long training session, culminating in an open book, certification examination. The North Carolina Cooperative Extension Service (NCCES) conducted the training and administered the examination. The certification-training program covered principles of wildlife damage management, wildlife laws and regulations, humane handling of animals and euthanasia, human health risks from exposure to wildlife, professional ethics, and sources of technical information. Between Octoberl995 and March 2000,7 certification-training sessions were held and 289 WDCA's were certified, with …


Landowners' Perceptions Of White-Tailed Deer Damage To Crops In Tennessee, Dawn L. Johnson, J. Mark Fly, Lisa Muller Oct 2000

Landowners' Perceptions Of White-Tailed Deer Damage To Crops In Tennessee, Dawn L. Johnson, J. Mark Fly, Lisa Muller

Wildlife Damage Management Conference Proceedings

We conducted a mail survey to determine Tennessee landowners' perceptions of white-tailed deer (Odocoileus virginianus) damage to crops, their tolerance for damage and the effectiveness of damage control methods. Fifty-five percent of landowners had wildlife damage and 47% had deer damage. The majority had light or moderate damage. The majority of participants who had taken measures to prevent damage used hunting. State-issued depredation permits were rated the most effective method of controlling damage. Although most survey participants did not have substantial deer damage, landowners with serious deer damage problems may need further assistance.


Suburban Goose Management: Insights From New York State, Bryan L. Swift Oct 2000

Suburban Goose Management: Insights From New York State, Bryan L. Swift

Wildlife Damage Management Conference Proceedings

New York State Department of Environmental Conservation (DEC) conducted studies in suburban Rockland County, New York during 1993-2000 to help local officials develop strategies to alleviate conflicts associated with local-nesting or "resident" Canada geese {Branta canadensis). Annual counts indicated a relatively stable population of approximately 2,500-3,000 resident geese in the county, far fewer than anecdotal reports suggested. Counts tended to increase in towns where there was little or no goose management, whereas numbers declined in towns with active goose management efforts (i.e., egg-addling, capture and removal, or use of border collies). Egg-addling programs did not result in immediate reduction of …


Evaluations Of Nicarbazin-Treated Pellets For Reducing The Laying And Viability Of Canada Goose Eggs, Kurt C. Vercauteren, Michael J. Pipas, Kenneth L. Tope Oct 2000

Evaluations Of Nicarbazin-Treated Pellets For Reducing The Laying And Viability Of Canada Goose Eggs, Kurt C. Vercauteren, Michael J. Pipas, Kenneth L. Tope

Wildlife Damage Management Conference Proceedings

The number of Canada geese (Branta canadensis) nesting in the United States is increasing rapidly, generating more complaints and problems associated with them. Overabundant geese can be a nuisance, threaten human health and safety, and cause damage to property. Nicarbazin (NCZ), a coccidiostat used in chicken production, has been documented to reduce egg production and viability. The reduction of reproduction through the use of NCZ could be a valuable aspect of an overall integrated goose management plan. We conducted studies at 5 sites in Nebraska in spring 2000 to evaluate the efficacy of NCZ-treated pellets for reducing the laying and …


Porcine Zona Pellucida Vaccine (Zonacon) As An Immunocontraceptive In Deer, Lowell A. Miller, Gary J. Killian, Paul D. Curtis Oct 2000

Porcine Zona Pellucida Vaccine (Zonacon) As An Immunocontraceptive In Deer, Lowell A. Miller, Gary J. Killian, Paul D. Curtis

Wildlife Damage Management Conference Proceedings

Abstract: Research on a PZP contraceptive vaccine was performed at 2 sites; Penn State University and Seneca Army Depot in upper New York. The Penn State study included immune response, hormone analysis, fawning and behavioral analysis. The Seneca depot studied behavioral and fawning response in a semi-free ranging setting. At Penn State University, in a 7 year study, does were actively immunized for two years resulting in a 90% reduction in fawns. They were followed for 5 more years to determine if the effect was reversible. The reduction in fawning over the 7 years was 72%. Most deer returned to …


Effects Of Intense Deer Herbivory On The Herbaceous Understory At Trillium Trail, Tiffany Knight, Susan Kalisz, Lisa Smith, Joann Davis Oct 2000

Effects Of Intense Deer Herbivory On The Herbaceous Understory At Trillium Trail, Tiffany Knight, Susan Kalisz, Lisa Smith, Joann Davis

Wildlife Damage Management Conference Proceedings

Due to a synergism of many human-mediated factors, white-tailed deer (Odocoileus virginianus) populations have increased dramatically throughout many forests throughout the northeastern North America over the last 50 years. The increase in deer populations negatively impacts plants through a variety of mechanisms, which can include increased consumption, trampling, and soil compaction. To preserve the plants in our forests, managers need to understand both how increases in the deer population impact the overall plant community as well as the individual plant species within the community. In general, the impact of deer presence on the overall plant community has been studied by …
