Lesser Scaup Depredation And Economic Impact At Baitfish Facilities In Arkansas, M. Chad Philipp, Michael D. Hoy
Lesser Scaup Depredation And Economic Impact At Baitfish Facilities In Arkansas, M. Chad Philipp, Michael D. Hoy
Great Plains Wildlife Damage Control Workshop Proceedings
During the winters of 1994-95 and 1995-96, unusually large numbers of diving ducks were observed on baitfish facilities in Arkansas. Historically, lesser scaup (Aythya affinis) inhabited baitfish ponds with little reported impact on minnow production, and thus little attention was paid to the birds. Unfortunately, minnow crops in the spring of 1995 fell short of expectations and immediate attention became focused on the role lesser scaup may have had on that minnow shortage. Subsequently, lesser scaup were collected from baitfish facilities in an effort to determine their effect on commercial fish farms. Two hundred and twenty-three lesser scaup …
Cost-Effectiveness Of Predator Damage Management Efforts To Protect Sheep In Idaho, Mark D. Collinge, Craig L. Maycock
Cost-Effectiveness Of Predator Damage Management Efforts To Protect Sheep In Idaho, Mark D. Collinge, Craig L. Maycock
Great Plains Wildlife Damage Control Workshop Proceedings
Cost-effectiveness of ADC’s predator damage management efforts was identified as an issue of concern during preparation of an environmental assessment (EA) on predator damage management in southern Idaho. A specific benefit-cost analysis of ADC’s efforts to protect sheep in southern Idaho was prepared to address this issue. This analysis involved a comparison of the difference between 1) the value of livestock losses sustained with a control program in place, plus the costs of implementing the program, and 2) the value of losses that could reasonably be expected without the program in place. This difference, divided by the cost to implement …

Welcome, Charles Lee
Great Plains Wildlife Damage Control Workshop Proceedings
It is a pleasure to welcome you to the 13th Great Plains Wildlife Damage Workshop. It has been 24 years since the 1st Great Plains Workshop was held in Manhattan, Kansas, in December 1973. Attendance has varied throughout the years; focus of the workshop has changed and has evolved to where it is today. As I look around the room, I still see a lot of interest. I still get a lot of calls about wildlife damage control, and I realize there is a great need to share the information that each of us has about wildlife damage control. That …
A Comparison Of Attitudes Held By Wildlife Damage Managers And Animal Rights Activists, James B. Armstrong, Melissa E. Hutchins
A Comparison Of Attitudes Held By Wildlife Damage Managers And Animal Rights Activists, James B. Armstrong, Melissa E. Hutchins
Great Plains Wildlife Damage Control Workshop Proceedings
We designed an instrument to measure attitudes about a variety of animal use issues, collect information on animal-related activities, and determine demographic characteristics of the sample. We administered the instrument to 151 Animal Rights Information and Education Service (ARIES) and 150 National Animal Damage Control Association (N ADC A) members. Based on analysis of the data, we concluded that these 2 groups differ greatly on their attitudes about human use of animals. In addition, they differ greatly in background and types of activities in which they participate. Thus, attempts to bring these groups together for discussion must start with the …
Cue Enhancement Of Lithium-Chloride-Induced Mutton/Sheep Aversions In Coyotes, Ray T. Sterner
Cue Enhancement Of Lithium-Chloride-Induced Mutton/Sheep Aversions In Coyotes, Ray T. Sterner
Great Plains Wildlife Damage Control Workshop Proceedings
In an enclosure-type study, I investigated the use of odor, auditory, and visual cues to enhance lithium-chloride (LiCl)- induced prey aversion in coyotes (Canis latrans). Eight adult, male, wild-caught coyotes that killed 2 adult sheep during successive daily, 1 -hr trials were assigned to LiCl- and sodium-chloride (NaCl)-bait groups. The 4 LiCl-bait coyotes were sequentially presented with leg-of-sheep and whole-sheep carcasses injected with a 33% LiCl water solution (4.5 ml/kg) 1 -hr daily until bait shy. The 4 NaCl coyotes were exposed to baits and carcasses injected with 25% NaCl/water solution (4.5 ml/kg) for matched trials. Additionally, 2 …
Resolving Human-Large Felid Conflicts Associated With Protected Areas In India, N.P.S. Chauhan, V.B. Sawarkar, H.S. Pabla
Resolving Human-Large Felid Conflicts Associated With Protected Areas In India, N.P.S. Chauhan, V.B. Sawarkar, H.S. Pabla
Great Plains Wildlife Damage Control Workshop Proceedings
In India, the past 2 decades of improved wildlife management practices along with rigid legal provisions have resulted in increased populations of the endangered carnivores: tiger (Panthera tigris), lion (Panthera leo), and leopard (Panthera pardus) in protected areas (PAs). Over this time period, human and livestock populations in and around PAs have also increased substantially. Intense human use and commensurate cattle grazing activity in associated forests have invariably lead to confrontation with these carnivores. Incidences of human- and cattle-killing by tiger, lion, and leopard have increased in and around PAs. Ongoing conflicts occur with …
Environmental Assessment Of Wildlife Damage Control For Wildlife Protection, Michael J. Bodenchuk
Environmental Assessment Of Wildlife Damage Control For Wildlife Protection, Michael J. Bodenchuk
Great Plains Wildlife Damage Control Workshop Proceedings
Wildlife damage management for the protection of wildlife resources was common in the early days of wildlife management. It may once again become an important endeavor. The Utah Animal Damage Control program has conducted several projects for the protection of specific wildlife species. Case histories of these projects are discussed, and a wildlife damage management program which integrates resources as well as control technologies is presented.
Predation Of Big Game And Livestock In The Texas Trans-Pecos, S. Kemble Canon
Predation Of Big Game And Livestock In The Texas Trans-Pecos, S. Kemble Canon
Great Plains Wildlife Damage Control Workshop Proceedings
Predation of livestock and big game remains a matter of concern for ranch managers and operators in the Trans-Pecos. Current evidence indicates that mountain lions (Felis concolor), bobcats (Lynx rufus), and coyotes (Canis latrans) are the primary predators involved, although little information is available on bobcats. A gradual shift from sheep to cattle management has resulted in a corresponding decrease in the intensity of predator control efforts for livestock protection. However, potential lease hunting income has renewed predator control efforts for protection of the 3 primary big game species, pronghorn antelope (Antilocapra americana), …
Curbing The Illegal Use Of Pesticides In Predator Control, Jeff Jacoby, Martin Fletcher, Ted Warfield
Curbing The Illegal Use Of Pesticides In Predator Control, Jeff Jacoby, Martin Fletcher, Ted Warfield
Great Plains Wildlife Damage Control Workshop Proceedings
In June 1993, the Agricultural Products Group of FMC responded to reports of alleged illegal, off-label use of its product Furadan 4F and other pesticide products in baiting and poisoning predators. The target of these reported illegal carcass-baiting incidents were principally coyotes (Canis latrans), which cause significant losses to the sheep industry. The FMC undertook an effort to determine the scope of the problem and how best to address the issue. This included conducting extensive measurable research among sheep ranchers and agrichemical dealers in 4 selected pilot states: Colorado, Montana, South Dakota, and Wyoming. Qualitative interviews were also …
Research Priorities In Wildlife Damage Management, James E. Miller
Research Priorities In Wildlife Damage Management, James E. Miller
Great Plains Wildlife Damage Control Workshop Proceedings
Based on a survey of 97 wildlife damage management professionals (60% response rate of 161 mailed questionnaires), field, research, and administrative personnel felt that the top 3 current wildlife damage management (WDM) research needs were: development of more effective and efficient techniques of damage assessment, effectiveness of education and conflict resolution programs on WDM issues, and repellent/aversive techniques. Respondents indicated that human dimensions research related to effectiveness of public education and conflict resolution would be the highest future research need. Large and small mammals were identified as key species groups needing research with preventive methods and aversive agents as practices …
Wyoming's M-44 Program: An Overview And Assessment Of Private And Commercial Applicators, Henry R. Uhden
Wyoming's M-44 Program: An Overview And Assessment Of Private And Commercial Applicators, Henry R. Uhden
Great Plains Wildlife Damage Control Workshop Proceedings
Wyoming's legislation funding predator control has progressed from a bounty system, to a mill levy system, to the current fee assessment per head. The Wyoming Department of Agriculture administers an M-44 predator control program for private and commercial applicators' use with livestock depredators. As predatory impacts on livestock have increased, use of M- 44 has also broadened. The M-44 is a mechanical device utilizing a spring-activated ejector, that propels the dry toxicant sodium cyanide into the mouth of the target species when pulled. Death of the animal is accomplished by inhalation of hydrogen cyanide which forms when sodium cyanide comes …
Livestock Herding Dogs: A Unique Application For Wildlife Damage Management, Roger A. Woodruff, Jeffrey S. Green
Livestock Herding Dogs: A Unique Application For Wildlife Damage Management, Roger A. Woodruff, Jeffrey S. Green
Great Plains Wildlife Damage Control Workshop Proceedings
Canada geese (Branta canadensis) and white-tailed deer (Odocoileus virginianus) have caused increasing problems for people both in urban and agricultural environments. In many instances, traditional methods of resolving conflicts caused by these species have proven ineffective or impractical. Some property owners and others have begun to use livestock herding dogs to haze geese and other wildlife from areas where they are not wanted. We report on the applications and effectiveness of this technique as employed on golf courses, farms, and other areas. The use of trained herding dogs appears to be a feasible and effective method …
Financial Compensation For Wildlife Damage: A Review Of Programs In North America, Kimberly K. Kessler
Financial Compensation For Wildlife Damage: A Review Of Programs In North America, Kimberly K. Kessler
Great Plains Wildlife Damage Control Workshop Proceedings
Financial compensation is 1 of several management options proposed as alternatives to traditional wildlife damage management techniques. However, little is known about compensation programs currently in place. I surveyed United States and Canadian fish and wildlife programs to obtain information on the species causing damage, type of damage, extent of reimbursement, and budget for wildlife damage compensation programs. Of the 58 respondents, 36% have a compensation program, and 64% loan equipment and/or provide supplies for wildlife damage management. Programs compensating landowners for damage caused by deer (Odocoileus spp.), black bear (Ursus americanus), elk (Cervus elaphus), …
Dynamics Of Wildlife Damage Management, Bobby R. Acord
Dynamics Of Wildlife Damage Management, Bobby R. Acord
Great Plains Wildlife Damage Control Workshop Proceedings
Wildlife damage management is a dynamic profession. Our focus has shifted from dealing with primarily agricultural interests. In addition to agricultural issues, we now deal with endangered species protection, human health and safety, and wildlife damage management issues in the urban environment. The dynamics of wildlife damage management are influenced by the changing needs of society, professionalism among our ranks, and the political process. Professionalism and meeting the needs of the public continue to be the most important part of the dynamics of wildlife damage management.
Effective Repellency Concentration Of Bird Shield Repellent(Tm) With Methyl Anthranilate To Exclude Ducks And Geese From Water Impoundments, Leonard R. Askham
Effective Repellency Concentration Of Bird Shield Repellent(Tm) With Methyl Anthranilate To Exclude Ducks And Geese From Water Impoundments, Leonard R. Askham
Great Plains Wildlife Damage Control Workshop Proceedings
Laboratory studies were conducted to establish the effective repellency concentration (ECR) of Bird Shield Repellent(TM) on mallard ducks (Anas platyrhynchos) and domestic geese for fresh water impoundments. Six concentrations of the repellent compound, ranging from 90 ppm to 2,890 ppm, were placed in small ponds in 2 aviaries and bird behavior monitored for 7 days. Concentrations <360 ppm did not limit either of the test species' activities (drinking or bathing) in the impoundments. Concentration >725 ppm precluded most activity after an initial exposure. Dissolved oxygen tended to decrease after an initial rise and pH increased slightly. Impoundments became discolored with higher concentrations of the repellents' methyl anthranilate precipitates in 24 hr.
Wild Ungulate Depredation On Winter Wheat: Effects On Grain Yield, Dennis D. Austin, Philip J. Urness
Wild Ungulate Depredation On Winter Wheat: Effects On Grain Yield, Dennis D. Austin, Philip J. Urness
Great Plains Wildlife Damage Control Workshop Proceedings
The effects of big game grazing of winter wheat on grain yield were studied during 12 trials in northern Utah between 1990-92. Differences in yield were measured for each trial using 20 sets of 1-m2 plots protected and variously grazed by mule deer (Odocoileus hemionus), pronghorn (Antilocapra americana) and Rocky Mountain elk (Cervus elaphus) in a randomized block design along the edges of sampled fields. Plots were hand cut at the beginning of commercial harvest. Grazing impacts were indexed by nighttime counts of game animals, pellet-group counts, and ocular estimates of percent track …

Survey Of The Nuisance Wildlife Control Industry With Notes On Their Attitudes And Opinions, Thomas G. Barnes
Great Plains Wildlife Damage Control Workshop Proceedings
A total of 138 nuisance wildlife control operators (NWCO) attending a wildlife control operators short-course were surveyed for information about their business and attitudes regarding management of urban wildlife problems. One hundred and thirty-one (94.9% response rate) returned the survey. Seventy-two percent of the respondents operated a nuisance wildlife business. Of these respondents, 47.7% also operated a full-time pest control business. Over 65% of NWCO had been in business <5 years and 89% reported their business was successful as a result of either increased nuisance animal problems, satisfied customers, a growing customer base, enjoyment of their work, or by providing a high level of service. Over 30% of NWCO had annual billings >$ 100,000. Respondents based fees on either the animal species and number removed, on a contract or flat fee basis, or based on time and number of trips required to resolve …
Canine And Gray Fox Rabies Epizootics In Texas, Keith A. Clark, Pamela J. Wilson
Canine And Gray Fox Rabies Epizootics In Texas, Keith A. Clark, Pamela J. Wilson
Great Plains Wildlife Damage Control Workshop Proceedings
In 1994, 2 ongoing rabies epizootics were declared a state health emergency: canine rabies in South Texas and gray fox (Urocyon cinereoargenteus) rabies in West-Central Texas. Prior to 1988, rabid coyotes (Canis latrans) were infrequently reported in Texas. In 1988, Starr and Hidalgo counties, located in extreme South Texas, experienced an epizootic of canine rabies resulting in 11 laboratory-confirmed cases of canine rabies in domestic dogs (Canis familiaris) and 6 cases in coyotes. By 1991, the epizootic had expanded approximately 160 km north of the United States (US)-Mexico border and included 10 counties. During …
Incidence Of Giardia In Beaver And Nutria In Southeast Texas, Brett G. Dunlap
Incidence Of Giardia In Beaver And Nutria In Southeast Texas, Brett G. Dunlap
Great Plains Wildlife Damage Control Workshop Proceedings
Beaver (Castor canadensis) have long been associated as carriers of Giardia, a flagellated protozoan parasite that inhabits the gastrointestinal tract of its host species. However, very few studies have been conducted on Giardia occurrence in beaver populations of southeastern United States. Nutria (Myocastor coypus) are similar to beavers but have not been researched with regard to Giardia infection and transmission. From October 1992 through September 1993, 100 beaver and 30 nutria were collected from areas throughout southeast Texas as part of wildlife damage management activities. Fecal samples from each individual were examined for the occurrence …
Biodiversity And Wildlife Damage Management, Ronald G. Eckstein, Robert C. Willging
Biodiversity And Wildlife Damage Management, Ronald G. Eckstein, Robert C. Willging
Great Plains Wildlife Damage Control Workshop Proceedings
The concept of managing natural resources to maintain and restore biodiversity has received increased emphasis from resource managers in recent years. Many state and federal land management agencies have incorporated biodiversity concepts into management plans and programs. Active management of both wildlife habitats and populations must increase as natural systems are simplified and fragmented by human activities. Wildlife damage management programs can be compatible with ecosystem management and maintenance of biodiversity. Species that are widespread but rare and, in particular, species with small and isolated populations remain at risk from environmental and genetic changes, competition, parasitism, and predation. There are …
Human Health Concerns In The Practice Of Wildlife Damage Management, John R. Fischer
Human Health Concerns In The Practice Of Wildlife Damage Management, John R. Fischer
Great Plains Wildlife Damage Control Workshop Proceedings
This paper describes diseases that are transmissible from animals to human beings. In many cases, the diseases are contracted by direct contact with the animals. However, several of the diseases are associated with vectors rather than with direct animal contact. Wildlife damage control agents or other wildlife professionals often cannot avoid situations that put them at risk. However, disease may be prevented by knowledge of the risk, and by following simple procedures to minimize risk. Risk may be minimized in many cases with knowledge of transmission modes, endemic areas, and specific preventative measures such as avoidance of known sources of …

Using Telemetry Equipment For Monitoring Traps And Snares, Thomas D. Halstead, Kenneth S. Gruver, Robert L. Phillips, Richard E. Johnson
Great Plains Wildlife Damage Control Workshop Proceedings
Specialized radio transmitters were developed for use in monitoring large mammal trap and snare activity. Prototype devices were manufactured by 4 wildlife telemetry companies based on specifications we developed in consultation with electronic engineering personnel. Power outputs from individual transmitters ranged from 10 to 100 milliwatts (mw). Range testing in the gently rolling terrain of northeastern Colorado indicated that ground-tracking distances with truck-mounted dual beam antennas exceeded 40 km. Field tests were conducted using transmitters with traps and foot snares set for coyotes (Canis latrans) in California, black bears (Ursus americanus) in Oregon, and mountain lions …
Plastic Visual Barriers Were Ineffective At Reducing Recolonization Rates Of Prairie Dogs, Scott E. Hygnstrom
Plastic Visual Barriers Were Ineffective At Reducing Recolonization Rates Of Prairie Dogs, Scott E. Hygnstrom
Great Plains Wildlife Damage Control Workshop Proceedings
Two plastic visual barriers were ineffective in controlling expansion of 7 active black-tailed prairie dog (Cynomys ludovicianus) colonies and recolonization of 7 toxicant-treated sections of colonies. Barriers constructed with Sno-Strap, a 15.2- cm wide band of high-tensile polyethylene plastic, were destroyed by wind action within 3 weeks. Barriers constructed with Tensar® snowfence cost $2.10/m and retained their structural integrity for 3 years with occasional maintenance. Recommendations are provided to increase effectiveness of visual barriers.
Deer Exclusion Efforts To Reduce Crop Damage In Michigan And Northeast Wisconsin, Jim Isleib
Deer Exclusion Efforts To Reduce Crop Damage In Michigan And Northeast Wisconsin, Jim Isleib
Great Plains Wildlife Damage Control Workshop Proceedings
A random sample of 93 deer-fenced farms in northern Lower and Upper Michigan and northeast Wisconsin and 250 non-deer-fenced farms in 5 Upper Michigan counties with high white-tailed deer (Odocoileus virginianus) populations was surveyed by mail using 2 different questionnaires. High-tensile electric was the most commonly used type of deer exclusion fence. A 1.8 m (6 ft) height apparently provided the best balance between effectiveness, cost, and ease of installation. Fence users perceived that 2.4 m (8 ft) woven wire was most effective. However, the high cost of installation limited widespread use. Other types of fence with inconsistent …
Effectiveness Of Squirrel Fencing For Protecting Pecan Groves, Mcalister D. Maxwell, J. Grant Huggins, Clark E. Adams
Effectiveness Of Squirrel Fencing For Protecting Pecan Groves, Mcalister D. Maxwell, J. Grant Huggins, Clark E. Adams
Great Plains Wildlife Damage Control Workshop Proceedings
During 1994, we tested the hypothesis that an energized, high-tensile wire fence prevents fox squirrels (Sciurus niger) from crossing into a pecan (Carya illinoensis) grove. When the fence was energized, we recorded fewer (P = 0.03) trips across the fence by squirrels (n - 19) and fewer (P < 0.001) telemetry fix-points in the pecan grove. Effective squirrel fencing may offer wildlife managers an alternative method of damage prevention. Ecological ramifications to target and non-target species are discussed.

Current Research On Improving Capture Devices For Coyotes, Robert L. Phillips, Kenneth S. Gruver
Great Plains Wildlife Damage Control Workshop Proceedings
Nine types of footsnares were tested on captive coyotes (Canis latrans) at the United States Department of Agriculture Predator Research Facility. Preliminary results indicate that the E-Z Lee, Nelson, Freemont, and Godwin leg snares can be effective in restraining coyotes while causing only minor leg injuries. Additional testing will be required to determine the effectiveness of these devices in different field situations. Four types of coyote leg-hold traps were evaluated to determine the injuries they inflict on captured coyotes. The No. 3 1/2 McBride padded trap caused the least injury in comparison to 3 other trap models that …
Wildlife Damage Managers And Euthanasia, Robert H. Schmidt
Wildlife Damage Managers And Euthanasia, Robert H. Schmidt
Great Plains Wildlife Damage Control Workshop Proceedings
Wildlife damage managers regularly are faced with decisions that include whether and how animals will be killed. Euthanasia refers to death without pain or distress, i.e., a humane death. The American Veterinary Medical Association has developed guidelines for euthanasia (Andrews et al. 1993). These guidelines affect many of the methods and technologies involved in wildlife damage management. Carbon dioxide, carbon monoxide, barbiturates, and gunshots are appropriate methods of euthanizing wildlife when necessary and when applied in the prescribed manner.
An Evaluation Of Oklahoma's Depredation Program For Handling Deer Damage To Agricultural Crops, Michael G. Shaw
An Evaluation Of Oklahoma's Depredation Program For Handling Deer Damage To Agricultural Crops, Michael G. Shaw
Great Plains Wildlife Damage Control Workshop Proceedings
A stepwise approach was developed in 1993 to handle agricultural damage complaints caused by white-tailed deer (Odocoileus virginianus). Results from 2 seasons were evaluated to determine the effectiveness of the procedures implemented. Approximately half of the damage complaints received were handled by prescribing non-lethal techniques such as fencing, harassment, and repellents. The remainder of the complaints required 1 or more types of lethal control. Although doe harvest rates were similar under the 2 permit options, Damage Control Assistance Permits (DCAP) provided several distinct advantages over out of season shooting using Depredation Permits (DEPR). The DCAP permits increased hunting …
Depredation Of Catfish By Double-Crested Cormorants At Aquaculture Facilities In Oklahoma, Robert L. Simmonds Jr., Alexander V. Zale, David M. Leslie Jr.
Depredation Of Catfish By Double-Crested Cormorants At Aquaculture Facilities In Oklahoma, Robert L. Simmonds Jr., Alexander V. Zale, David M. Leslie Jr.
Great Plains Wildlife Damage Control Workshop Proceedings
Oklahoma has about 324 ha of surface water in catfish (Ictalurus spp.) production. The state also supports a large number of migrating and wintering piscivorous birds, particularly double-crested cormorants (Phalacrocorax auritus). To address concerns of aquaculture facility operators regarding loss of fish to cormorants, we asked 11 operators to conduct regular counts of piscivorous birds at each facility. These data were used to determine factors affecting cormorant density at facilities and to estimate amount of catfish lost to cormorant depredation. Cormorant density (birds/ha/day) was positively correlated with surface area of water in production at facilities <10 ha (r = …
