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 …
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.
Effects Of Mule Deer Grazing On Alfalfa Seed Production, Dennis D. Austin, Philip J. Urness
Effects Of Mule Deer Grazing On Alfalfa Seed Production, Dennis D. Austin, Philip J. Urness
Great Plains Wildlife Damage Control Workshop Proceedings
Evaluation of crop loss caused by mule deer (Odocoileus hemionus) grazing on alfalfa grown for seed harvest was studied in northern Utah. Results indicated (1) wire baskets used to protect non-grazed plots did not affect alfalfa production, and (2) alfalfa seed crop loss was directly correlated with alfalfa hay crop loss. Consequently, methods used to evaluate crop loss to alfalfa hay may be applied to alfalfa seed.
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 …
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.
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.
Immunocontraception And Possible Application In Wildlife Damage Management, Lowell A. Miller
Immunocontraception And Possible Application In Wildlife Damage Management, Lowell A. Miller
Great Plains Wildlife Damage Control Workshop Proceedings
lmmunocontraception technology appears to have viable application in wildlife damage management. However, administration of these vaccines is presently performed by syringe injection or remote delivery by darts or bio-bullets. In order for immunocontraception to be successful for broad scale application to free-roaming animals, the vaccine must be delivered in an oral form. Recent advances in molecular biology, immunology, and pathology of mucosal infection gives us tools to develop effective oral vaccines. Oral immunocontraceptive vaccine encapsulated in adhesive liposomes or non-virulent live vectors holds promise as a practical approach for immunocontraception of free-roaming wildlife. Issues of safety, species specificity, regulatory constraints, …

Protecting Juvenile Salmonids From Gull Predation Using Wire Exclusion Below Hydroelectric Dams, John E. Steuber, Mikel E. Pitzler, J. Gary Oldenburg
Protecting Juvenile Salmonids From Gull Predation Using Wire Exclusion Below Hydroelectric Dams, John E. Steuber, Mikel E. Pitzler, J. Gary Oldenburg
Great Plains Wildlife Damage Control Workshop Proceedings
Predation by ring-billed gulls (Larus delawarenis) has been identified as a significant threat to migrant steelhead and salmon (Oncorhynchus spp.) smolt in the Columbia and Snake Rivers. Bird predation appears highest immediately below hydroelectric facilities. Installation of overhead wire/cable exclusion systems over the tailrace area of 12 dams has been completed to reduce gull predation. Data collected from 1 of the facilities as well as observations from other dams indicate that overhead wire/cable exclusion systems are effective in reducing predation by gulls.
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 …
The Puma In The Central Mountains And Great Plains, Jay W. Tischendorf, F. Robert Henderson
The Puma In The Central Mountains And Great Plains, Jay W. Tischendorf, F. Robert Henderson
Great Plains Wildlife Damage Control Workshop Proceedings
Current status of the puma, Felis concolor, in the central mountains and Great Plains of Canada and the United States is discussed. Recent specimens and verified sightings are reviewed. Based on growing evidence, the puma has the potential to recolonize much of this region. Minor depredation problems can be expected, particularly as puma numbers increase and their range expands. This species is highly adaptable and extremely elusive, and its detection requires special skills. Professional wildlifers must be prepared to meet the dual challenges of managing both for recovery of this relatively rare carnivore and for its coexistence with humans.
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.
Ripening Field Corn Lost To Wildlife In 1993, Alice P. Wywialowski
Ripening Field Corn Lost To Wildlife In 1993, Alice P. Wywialowski
Great Plains Wildlife Damage Control Workshop Proceedings
Ripening field corn lost to wildlife was measured in fall 1993 in 10 midwestern states that have produced 83% of the field corn in the United States over the past 10 years. Sampling of damage was stratified by producer expectation of likely wildlife damage or unlikely wildlife damage. Damage was assessed immediately before harvest. Two plots that measured 4.5 m x 2 rows were assessed in each selected field. Of assessed fields, wildlife damage was present in 340 of 1,259 (27.0%) likely damaged fields and 108 of 1,243 (8.7%) unlikely damaged fields. As a percentage of harvested production, birds (Aves) …

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 …
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), …
The Efficacy Of Naphthalene And Sulfur Repellents To Cause Avoidance Behavior In The Plains Garter Snake, Dennis M. Ferraro
The Efficacy Of Naphthalene And Sulfur Repellents To Cause Avoidance Behavior In The Plains Garter Snake, Dennis M. Ferraro
Great Plains Wildlife Damage Control Workshop Proceedings
The efficacy of naphthalene, sulfur, and a commercial combination of these chemicals as a repellent against the plains garter snake (Thamnophis radix) was investigated. Behavioral tests were conducted using 96 recently captured snakes to determine whether significant avoidance results from the presence of these chemicals. Field tests were performed at 24 locations in the snakes' home range and in unfamiliar habitats. In both home ranges and unfamiliar habitats application of potential repellents did not result in significant avoidance behavior. The snakes may be able to sense these volatile chemicals, but the stimuli were unable to alter their behavior. …

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 …
Current Research On Improving Capture Devices For Coyotes, Robert L. Phillips, Kenneth S. Gruver
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 …
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 = …
Using Sound, Visual, And Tactile Products To Repel Birds, Mona Zemsky
Using Sound, Visual, And Tactile Products To Repel Birds, Mona Zemsky
Great Plains Wildlife Damage Control Workshop Proceedings
Birds are typically thought of as beautiful, graceful, tuneful creatures by the general public. However, there are many reasons to control birds. Birds and their droppings can create unsightly visual conditions and an unhealthy atmosphere that promotes disease transmission. In addition, cleaning costs including time spent, and property, equipment, or product damage can cause financial loss. Some bird control products, though widely used, are not suitable in many situations. For environmental and safety reasons, poison perches, poison grain and shotguns may not be ideal choices under certain circumstances. Because of high cost and unfeasibility, netting and spikes may be inappropriate. …
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 …
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 …
The Oral Rabies Vaccination Project And The Experimental Use Of Raboral V-Rg In The South Texas Canine Rabies Epizootic, M. Gayne Fearneyhough
The Oral Rabies Vaccination Project And The Experimental Use Of Raboral V-Rg In The South Texas Canine Rabies Epizootic, M. Gayne Fearneyhough
Great Plains Wildlife Damage Control Workshop Proceedings
Beginning in October 1988, Texas experienced the onset of an expanding epizootic of canine rabies in far South Texas. That epizootic now involves 18 counties, with 522 laboratory confirmed cases as of December 1994. Approximately 50% of those cases have occurred in coyotes (Canis latrans) and most of the remainder in domestic dogs. Forty-three "spill over" cases have been reported in 7 other species, both wild and domestic. Since 1988, over 1600 people in South Texas have received postexposure rabies treatment due to potential exposure to a rabid animal and 2 human deaths have been attributed to this virus strain. …
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 …
