The Role Of Research In Expanded Regional Management Of Double-Crested Cormorants, Scott C. Barras, Mark E. Tobin
The Role Of Research In Expanded Regional Management Of Double-Crested Cormorants, Scott C. Barras, Mark E. Tobin
Wildlife Damage Management Conference
The number of double-crested cormorants (Phala crocorax auritus) breeding in the Great Lakes states and provinces has increased during recent decades. Their abundance and foraging habits have thrust this species into conflict with the aquaculture industry and fisheries interests. The U. S. Fish and Wildlife Service proposed a change in the management of double-crested cormorants recently to alleviate these conflicts, especially with aquaculture, natural resources, and federal fish hatcheries. Research activities should be an integral component of these expanded efforts to manage cormorants, including further investigations on cormorant impacts to the aquaculture industry and evaluations of the added benefits of …
Charismatic Mega-Fauna Or Vermin Vertebrate - Where Are You?, Gary J. San Julian
Charismatic Mega-Fauna Or Vermin Vertebrate - Where Are You?, Gary J. San Julian
Wildlife Damage Management Conference
Wildlife populations throughout much of the United States were decimated by the end of the 1800s. Many states established game agencies to protect wildlife and generate revenue through the sale of hunting licenses. These efforts were successful, populations grew, and citizens enjoyed seeing the large herbivores and camivores--the charismatic mega-fauna. In the past, most citizens and students had some tie with the farming community. Today's students often lack that link to the land and hunting. Wildlife agencies and universities are looking at ways to improve young professionals' understanding of the role hunting plays in management. Citizens that once left their …
Non-Lethal Harassment To Disperse Canada Geese In Winter Wheat Fields, Amy Villano, David Drake
Non-Lethal Harassment To Disperse Canada Geese In Winter Wheat Fields, Amy Villano, David Drake
Wildlife Damage Management Conference
Canada goose (Branta canadensis) populations have increased dramatically in the Atlantic Flyway during the last 50 years, primarily due to large increases in nonmigratory, resident Canada goose populations. Among the associated problems with the increase in goose numbers is grazing and trampling damage to forage crops like winter wheat. Reducing or eliminating goose presence on winter wheat fields is valuable to farmers because goose damage can result in a loss of yield and increased soil erosion. The objective of our study was to evaluate the efficacy of 3, non-lethal harassment techniques (flagging, propane cannon, and combination of flagging and propane …

Developing A Curriculum For The Nuisance Wildlife Control Industry In New York, Paul D. Curtis, Jill Shultz, Lynn A. Braband, Gordon Batcheller, Louis Berchielli
Wildlife Damage Management Conference
The nuisance wildlife control industry continues to expand in New York State. Each year during the past 5 years, approximately 1,200-1 ,400 private Nuisance Wildlife Control Operators (NWCOs) were given authority to handle wildlife conflicts by the New York State Department of Environmental Conservation (DEC). These NWCOs were required to complete a trapper education course, and a personal interview or exam prior to obtaining a permit. The education and experience requirements for NWCOs varied by region in New York. The goals of this project were to: (1) develop a core curriculum for individuals who desired to handle nuisance wildlife and …
Assessment Of Economic Impacts From Deer In The Northeastern United States, David Drake, Joseph B. Paulin, Paul D. Curtis, Dan J. Decker, Gary J. San Julian
Assessment Of Economic Impacts From Deer In The Northeastern United States, David Drake, Joseph B. Paulin, Paul D. Curtis, Dan J. Decker, Gary J. San Julian
Wildlife Damage Management Conference
The white-tailed deer (Odocoileus virginianus) is perhaps the most recognizable species of wildlife in the United States. The economic benefits as a result of hunting, viewing, and photographing deer are in the hundreds of millions of dollars annually. Deer provide numerous ecological benefits as well. However, in many states, extremely large populations of deer are causing a negative impact. The objective of our study was to compile data for 13 northeastern states to gauge the economic impacts from unwanted deer-human interactions. Economic data were collected for property damage from deer-vehicle collisions, damage to high value agriculture (i.e. vegetable and fruit), …
Effectiveness Of A Perceived Solid Barrier As An Exclusion Fence To Prevent White-Tailed Deer Damage, George R. Gallagher, Heidi A. Keen, Robert H. Prince
Effectiveness Of A Perceived Solid Barrier As An Exclusion Fence To Prevent White-Tailed Deer Damage, George R. Gallagher, Heidi A. Keen, Robert H. Prince
Wildlife Damage Management Conference
We hypothesized that a visually solid barrier of cloth would provide an effective exclusion fence for free ranging white-tailed deer (Odocoileus virginianus). Three plots consisting of 2, 10 m x 10 m squares were established in pastures. Data were collected daily for consumption of com provided (2.27 kg) and events recorded by infrared game monitors. Following construction of the burlap fence at 1.7 m height, corn consumption decreased (0.07 ± 0.01 kg/day, P < .001). The number of Infrared monitor events recorded also decreased within the enclosures (2.13 ± 0.04 events/day, P < .001) compared to controls (46.0 ± 2.2 events/day). During the second stage of the experiment, two of the three plots were reestablished 45 days later. Fence heights began at 65 cm and were raised 15 cm each 5 days, until reaching 1.7 m. At 1.7 m, corn consumption decreased by 30% (1.56 ± 0.23 kg/day, P < .01). The number of infrared monitor-recorded events was also lower at fence heights >65 cm (P < .03). Results indicate that a visually solid barrier has potential to be an effective exclusion fence.

Urban Deer Control - Applicable Technologies, Earl L. Hodnett
Wildlife Damage Management Conference
White-tailed deer (Odocoileus virginianus) populations have grown to unprecedented levels in suburban areas throughout the eastern United States. Deer have adapted to the fragmented habitats of suburbia and have brought with them a variety of problems. Control of white-tailed deer in suburban and urban areas brings its own set of problems and unique challenges. Fairfax County, Virginia is a suburb of Washington, D.C. and is home to over one million residents. The deer herd in Fairfax county reached its peak in 1998 when nearly 5,000 deer/automobile collisions occurred. Since 1998, snipers from the Fairfax County Police Department Tactical Team have …
Perspectives Of The Private Wildlife Control Industry, Tim Julien
Perspectives Of The Private Wildlife Control Industry, Tim Julien
Wildlife Damage Management Conference
As urban and suburban areas have grown, a new industry has developed to provide service in dealing with wildlife-caused problems. State agencies have been faced with pressure to provide effective oversight to the persons providing wildlife damage services, or Wildlife Control Operators (WCOs). The National Wildlife Control Operators Association (NWCOA) can offer discussion and assistance on drafting administrative rules and can offer industry insight on the effects of these rules. This manuscript provides sample wording for a general administrative rule that can be used by state wildlife agencies to provide oversight to the WCO industry.

Wildlife Damage Management Education Needs: Survey Of Georgia County Fasat Agents, Michael T. Mengak
Wildlife Damage Management Conference
The Service and Outreach Program of the Warnell School of Forest Resources at the University of Georgia conducts an annual county agent training program: Forestry: Area Specialty Advanced Training (FASAT). This training is provided to one or more lead agents in each county cluster (2-4 counties) throughout Georgia. At the spring 2002 training, 58 agents were surveyed to assess their needs for wildlife damage management information and programs. Agents were asked to supply information on the type of training programs they would find most useful. Agents were also questioned about the nature of damage calls they received in the past …
Fencing Methods To Reduce Deer Damage, Kurt C. Vercauteren, Michael J. Lavelle
Fencing Methods To Reduce Deer Damage, Kurt C. Vercauteren, Michael J. Lavelle
Wildlife Damage Management Conference
The white-tailed deer (Odocoifeus virginianus) may cause more damage than any other wildlife species. Deer damage occurs in various forms including crop production, automobile accidents, aviation collisions on runways, disease transmission, degradation of natural ecosystems, and destruction of ornamental plantings. One practical method of controlling deer damage is through the use of exclusionary fencing. White-tailed deer are challenging to exclude as they are able to jump 3.0-m fences or fit through spaces > 20 cm wide. Some deer problems (disease outbreaks, aircraft runways, and busy highways in deer migration corridors) may necessitate the installation of effective fencing no matter what the …

The Wildlife Society And Wildlife Damage Management Professionals, Robert J. Warren
Wildlife Damage Management Conference
The Wildlife Society (TWS) recognizes wildlife-human interactions as both a challenge and an opportunity whereby we can serve the wildlife profession and human society. TWS first officially supported wildlife damage management professionals in 1959 when it created the TWS Committee on Economic Losses Caused by Vertebrates. In 1994, this committee ultimately became the TWS Wildlife Damage Management Working Group (WDMWG), whose goal is to better understand and manage the biological, ecological, social, political, legal, and economic aspects of wildlife-human interactions. The WDMWG has sponsored numerous symposia, workshops, publications, etc., all of which are designed to serve TWS, wildlife damage management …
Correlates Of Success For On-Site Releases Of Nuisance Black Bears In Great Smoky Mountains National Park, Jay E. Clark, Frank T. Van Manen, Michael R. Pelton
Correlates Of Success For On-Site Releases Of Nuisance Black Bears In Great Smoky Mountains National Park, Jay E. Clark, Frank T. Van Manen, Michael R. Pelton
Wildlife Damage Management Conference
Since 1990, wildlife biologists in Great Smoky Mountains National Park (GSMNP) have used capture and on-site release as a management technique to reduce recurrence of nuisance activity by black bears (Ursus americanus). On-site release involves capture and immobilization of bears that frequent developed areas, collection of biological data, and subsequent release in the area of capture. Our objective was to identify factors related to success of this technique. We classified 85 on-site releases of black bears as successes or failures based on post-release observations and subsequent management actions at the release site. The success rate of on-site releases in GSMNP …
The Ecological Role Of Mesopredators And The Long-Term Effects Of Mesopredator Control, L. Mike Conner, Lora L. Smith, Micah W. Perkins, Christopher K. Borg, M. Brent Howze, Anna E. Liner
The Ecological Role Of Mesopredators And The Long-Term Effects Of Mesopredator Control, L. Mike Conner, Lora L. Smith, Micah W. Perkins, Christopher K. Borg, M. Brent Howze, Anna E. Liner
Wildlife Damage Management Conference
Until approximately 20 years ago, mammalian predators were actively pursued by hunters and trappers for both sport and economic gain. However, during the past two decades fur prices have fallen precipitously, and sport hunting and trapping of mammalian predators is at an all-time low. Some suggest that decreased hunting and trapping pressure on mesomammal predators (e.g., raccoons, opossums, bobcats, foxes, coyotes, etc; hereafter, mesopredators) has resulted in increased mesopredator populations and a decline in many prey species. The role of mesopredators within southern forests is controversial, and there are few empirical studies on which to base management and political decisions …
The Development Of A Program To Reduce Damage From European Starlings At Dairies Using Drc-1339, Anthony G. Duffiney, Peter H. Butchko
The Development Of A Program To Reduce Damage From European Starlings At Dairies Using Drc-1339, Anthony G. Duffiney, Peter H. Butchko
Wildlife Damage Management Conference
In the winter in Michigan, European starlings (Sturnus vulgaris) congregate, sometimes in large numbers, at dairies to feed on the high energy components of cattle feed. Damage is incurred not only with the extensive consumption of the feed but also in a corresponding loss in milk production. Starlings are also suspected in the spread of diseases harmful to cattle. Effective control of starlings in these situations is limited to DRC-1339 which has been registered for this use for many years. However, it was rarely used, largely under the perception that effective control was difficult to achieve. In 1999, WS-MI launched …

Using A Geographical Information System To Evaluate Contributing Factors To Deer-Vehicle Collisions, Michael C. Farrell, Donald I. M. Enderle, Philip A. Tappe
Wildlife Damage Management Conference
An expanding human population combined with a growing white-tailed deer (Odocoifeus virginianus) population has resulted in an increase of deer-vehicle collisions in Arkansas. In response to this increase, we are using spatially explicit datasets integrated within a geographic information system (GIS) to identify county-level and site-specific factors contributing to deer-vehicle collisions. County-level information, such as human population densities /urbanization, deer density indices, and road densities, is being evaluated for use in identifying potential aggregations of deer-vehicle collisions. Site-specific information being evaluated includes physical factors such as landcover composition and arrangement, topography, and road characteristics. By incorporating these multi-scale data sets …

Using Color-Infrared Photography And Gis To Quantify Cattail Coverage In Wetlands, H. Jeffrey Homan, Linda B. Penry, George M. Linz
Wildlife Damage Management Conference
Analyzing changes in habitat features at very large scales with GIS requires digital images with both high spatial and spectral resolutions. As part of an experiment to reduce blackbird (Icterinae) damage to sunflower in North Dakota, we used large-scale infrared photography to monitor regrowth of herbicide-treated cattail (Typha spp.) in wetlands used by roosting blackbirds. We aerially photographed the wetlands at 460-610 m above ground level. All photographs were taken vertically through a 38-cm diameter port in the floor of the plane's fuselage. We used a SLR 35-mm camera loaded with Kodak Ektachrome® Professional Infrared EIR film. The photographs were …

The Potential Of Texture As A Deer Deterrent: The Slime Effect, Heidi A. Keen, George R. Gallagher, Robert H. Prince, Ted H. Touchstone
Wildlife Damage Management Conference
We examined the potential of altering the surface texture of plant material as a potential deterrent to consumption by white-tailed deer. Two u-shaped garden plots were divided into 16, uniform plots (2.2mx4.3m) each containing approximately 50 chrysanthemums (C. morifolium). The plots were randomly assigned to one of the treatments or as a control. Immediately after planting, ten plants were randomly selected and marked within each plot. Plants were misted and treatments applied by hand broadcast. Treatments consisted of methyl cellulose (38.2g) and two-levels of a proprietary polymer (9. lg and 45.5g). Upon contact with water, methyl cellulose became a viscous …

Development Of A Synthetic Materials Mimic For Vulture Olfaction Research, Richard E. Mauldin, Bruce A. Kimball, John J. Johnston, Jerome C. Hurley, Michael L. Avery
Wildlife Damage Management Conference
Since the early l 990's, an increase in damage associated with the activities of black (Coragyps atratus) and turkey (Cathartes aura) vultures has been observed. These activities include extensive damage to real and personal property. Vultures display an affinity for objects made of synthetic materials such as vinyl or plastic, and frequently damage items such as seat cushions, roof shingles, and caulking sealant. To explore whether this behavior in vultures is olfactorily driven, volatile compounds emitted by 21 vulture-damaged objects were collected and analyzed using purge-and-trap gas chromatography /mass spectrometry. Results from these analyses were tabulated and the 27 most …

Wildlife Damage Management Conference
The California least tern (Sterna antillarium brownii) is an endangered, small (<25 >cm), ground-nesting shorebird that winters along the Pacific Coast of Central America and nests in colonies on coastal dunes and beaches from southern Baja to San Francisco, California. It was one of the originally listed species contained in the Endangered Species Act in 1970. Major nest sites remain at Marine Corps Base Camp Pendleton. During the past 15 years, adult tern counts have increased from about 300 to over 600 breeding pairs at the site. This poster provides results of an empirical analysis of annual fixed-cost agreements (1995-2001) …
Wading Bird Management And Research On North American Aquaculture Facilities, Brian Dorr, Jimmy D. Taylor Ii
Wading Bird Management And Research On North American Aquaculture Facilities, Brian Dorr, Jimmy D. Taylor Ii
Wildlife Damage Management Conference
Aquaculture in North America varies geographically with respect to species cultured, annual production, size, complexity, and spatial arrangement of facilities. Species assemblages of predacious birds using aquaculture facilities also vary with many of these industry characteristics. Wading birds are highly adaptable, relatively ubiquitous throughout the aquaculture industry, and often associated with fish depredation problems at aquaculture facilities. Suitability of information regarding the impacts of wading birds to aquaculture varies dramatically by depredating species and industry sector. Great blue herons (Ardea herodias) cause considerable depredation losses on trout aquaculture in the Northeast, and current research suggests that little blue herons (Egretta …

Challenges Of Implementing The Double-Crested Cormorant Environmental Impact Statement, Kristina Casscles Godwin, Tommy King, Peter Butchko, Richard Chipman
Wildlife Damage Management Conference
Double-crested cormorant populations have increased over the last 20 years within the continental United States. Problems associated with this increase include impacts to commercial aquaculture, damage to property, vegetation, recreational fisheries, and natural resources, as well as concerns over inter-specific competition. Implementation of the forthcoming Environmental Impact Statement for the management of double-crested cormorants will be a monumental task. Several state and federal agencies, along with private citizens and various interest groups will have parts to play. USDA/APHIS/Wildlife Services is expected to have a large part in the implementation of the plan. We discuss the proposed actions to be taken …

Overview Of American White Pelican Impacts To Southeastern Aquaculture, D. Tommy King
Overview Of American White Pelican Impacts To Southeastern Aquaculture, D. Tommy King
Wildlife Damage Management Conference
In 1990, USDA Wildlife Services offices in Arkansas, Louisiana, and Mississippi began receiving complaints concerning American white pelicans (Pelecanus erythrorhynchos) foraging in commercial channel catfish (Jctalurus punctatus) ponds. Because of the relatively shallow pond depth and high fish stocking rates used by most producers, commercial aquaculture provides a near perfect foraging environment for an increasing American white pelican population. Although pelicans are not currently as numerous as double-crested cormorants (Phalacrocorax auritus), individual farmer losses to pelican predation can be devastating. American white pelicans are capable of eating about 2 kg per day and as many as 2000 pelicans have been …

Minimizing Use Of Aquaculture Ponds By Double-Crested Cormorants Phalacrocorax Auritus And Other Fish-Eating Birds, Andrew A. Radomski, Charles (Bo) Collins, Don Freeman
Wildlife Damage Management Conference
Methods used to minimize abundance of double-crested cormorant (Phalacrocorax auritus), great blue herons (Ardea herodias), and great egrets (Arded alba) at aquaculture facilities have limited success because of the birds' ability to habituate to the applied technique. The primary objectives of this study were to evaluate and quantify the effects of overhead lines on minimizing number of cormorants, egrets and herons. We measured the long-term (01 December 2000 to 14 April 2001) effectiveness of exclusion barriers positioned every 30 m at 8 aquaculture ponds in southeastern Arkansas and the post-removal of the barrier effects from 15 April to 31 May …

Municipal By-Laws Against Hunting In Quebec: An Obstacle To Wildlife Management And Damage Control, Gaétan Roy, Gaétan Hamel
Municipal By-Laws Against Hunting In Quebec: An Obstacle To Wildlife Management And Damage Control, Gaétan Roy, Gaétan Hamel
Wildlife Damage Management Conference
A study performed in 2000-2001, showed that a large number of Quebec's municipalities have adopted by-laws to control or forbid the discharge of firearms within their territorial limits. Among the aforementioned municipalities, 9% actually forbid or control hunting itself, while 62% forbid or control the use of firearms. Unfortunately, these by-laws are being implemented at a time when territories around cities are facing a substantial increase in wildlife management problems. The issue is compounded by the fact that the majority of these by-laws occur in areas where the incidence of wildlife-related damage to agriculture and vehicles are the highest. These …

Training Deer To Avoid Sites Through Negative Reinforcement, Dale L. Nolte, Kurt C. Vercauteren, Kelly R. Perry, Suzanne E. Adams
Wildlife Damage Management Conference
Deer frequently visit areas where they may cause damage. Incidents along roadways and runways inflict numerous injuries to animals and humans, and cause considerable economic losses. Concerns are increasing that deer interactions with domestic animals may contribute to spread of disease. Deer foraging in residential areas, agricultural fields, or plant propagation sites can impede growth and possibly survival of desirable plants. We conducted a series of trials to determine whether mild electric shock would induce place avoidance in deer. Shock was delivered through a device attached to a collar. A noise cue was emitted as an animal approached a defined …

Oral Rabies Vaccination: Reducing Economic Uncertainty Via Response Surface Analysis, Ray T. Sterner, Matthew M. Kling, Stephanie A. Shwiff, Dennis Slate
Wildlife Damage Management Conference
Economic uncertainty surrounds the distribution of Raboral V-RG7 as an oral rabies vaccine (ORV) bait for the containment or elimination of raccoon-variant rabies in the United States. This paper describes a costs-savings model of ORV. lt also describes Excel XP7 code that was prepared to compute potential net savings (NS) and benefit-cost ratios (BCRs) associated with Raboral V-RG7 bait distributions. Currently, baits and bait distributions are relatively expensive; individual baits are produced at a cost of $1.27 for federal use and typically dispensed at >75 baits/km2. Distribution is estimated at $8.62/km2, $15.80/km2, and $33.30/km2 for fixed-winged (FW), ground (Gnd), and …
