The Handbook Of Wildlife Depredation Techniques: A Synopsis, Tim Fagan, John Demaree
The Handbook Of Wildlife Depredation Techniques: A Synopsis, Tim Fagan, John Demaree
Great Plains Wildlife Damage Control Workshop Proceedings
In 1979, the Game Division Administration of the Wyoming Game and Fish Department (WGFD) appointed John Demaree and Tim Fagan to develop a handbook that would address the ever increasing problem of wildlife depredation. Field personnel were often times at a loss on how to deal with or evaluate the assorted types of damage situations they were encountering. Because Wyoming requires landowners to be reimbursed for damage done by big and trophy game and game birds to their crops and livestock, an evaluation and techniques handbook was desperately needed. The initial handbook, completed in January 1981, was 74 pages, and …
Laboratory Study On Bromadiolone: Effectiveness On Prairie Dogs And Secondary Hazards To Domestic Ferrets, Daryl D. Fisher, Robert M. Timm, Richard Poche, Scott E. Hygnstrom
Laboratory Study On Bromadiolone: Effectiveness On Prairie Dogs And Secondary Hazards To Domestic Ferrets, Daryl D. Fisher, Robert M. Timm, Richard Poche, Scott E. Hygnstrom
Great Plains Wildlife Damage Control Workshop Proceedings
Bromadiolone is a second generation anticoagulant that is currently registered as a toxicant controlling commensal rodents. This laboratory study was conducted to provide us with preliminary information on the effectiveness and secondary hazards of bromadiolone as a prairie dog (Cynomys spp.) toxicant. We planned to use this information to decide on the appropriateness of pursuing field research projects using this compound. For an overview on bromadio-lone, see Poche (1986). This was the second laboratory study we conducted on alternative prairie dog toxicants. The first, on chlorophacinone, was reported earlier (Fisher and Timm 1988). Our desire was not to directly com-pare …
A Cultural Method Of Reducing Pocket Gopher Impact On Alfalfa Yield, Bruce A. Jasch, Ronald M. Case, James C. Luchsinger
A Cultural Method Of Reducing Pocket Gopher Impact On Alfalfa Yield, Bruce A. Jasch, Ronald M. Case, James C. Luchsinger
Great Plains Wildlife Damage Control Workshop Proceedings
Low Input Sustainable Agriculture (LISA) strives to minimize input of agrichemicals for farmers while maintaining profits. Alfalfa fits into this scheme in 2 ways. First, the plains pocket gophers (Geomys bursarius) can reduce yield of alfalfa, thus an effective, economical means of control with minimal environmental impact would be desirable. Second, the increased use of alfalfa in rotation with row crops to increase soil nitrogen may increase pocket gopher problems by increasing their habitat. Our objective was to evaluate a cultural method to control pocket gopher damage, namely, by comparing 2 different varieties of alfalfa. One variety is tap-rooted (Wrangler) …

An Update On The Revision Of The Handbook, "Prevention And Control Of Wildlife Damage", Scott E. Hygnstrom, Robert M. Timm, Gary A. Larson
Great Plains Wildlife Damage Control Workshop Proceedings
Wildlife species have an important role in our environment and they provide many recreational, economic, and aesthetic benefits. Management of these species is necessary, however, when they cause damage to agricultural, industrial, and natural resources, and threaten personal property, public health, and safety. Published estimates indicate that commensal rodents, field rodents, and predators combined, cause >$2 billion in damage in North America annually. Because of the social and economic impacts of wildlife damage, there is a need for up-to-date information on the prevention and control of wildlife damage for producers, resource managers, administrators, and the public. The book, "Prevention and …
Movements Of Deer Mice And House Mice In A Sugarbeet Field In Western Nebraska, Dallas R. Virchow, Scott E. Hygnstrom
Movements Of Deer Mice And House Mice In A Sugarbeet Field In Western Nebraska, Dallas R. Virchow, Scott E. Hygnstrom
Great Plains Wildlife Damage Control Workshop Proceedings
In fall, 1990 we became involved in a National Pesticide Clearance Inter-regional Research Program (NPCIRP) project to test the efficacy of zinc phosphide in controlling vole (Microtus spp.) damage in sugar beets in Western Nebraska. During the course of the project we observed some rather remark-able short-term movements by deer mice (Peromyscus maniculatus). Although mice have the physical capability of moving up to 300 m in 1 hr (Rawson 1964), typical observed-range lengths are much less. Farming practices that affect food availability and cover likely affect small mammal movements (Warburton and Klimstra 1984, Vessey 1987). Average daily movements of white-footed …
Reducing Nuisance Canada Goose Problems Through Habitat Manipulation, Michael R. Conover
Reducing Nuisance Canada Goose Problems Through Habitat Manipulation, Michael R. Conover
Great Plains Wildlife Damage Control Workshop Proceedings
Urban populations of Canada geese (Branta canadensis) cause considerable problems when large numbers congregate in parks, playing fields, and backyards. In most cases, geese are drawn to these sites to feed on the lawns. I tested whether geese have feeding preferences for different grass species. Captive Canada geese preferred Kentucky bluegrass (Poa pratensis) and disliked tall fescue (Festuca arundinaceae) over colonial bentgrass (Agrostis tenuis cv. Highland), perennial ryegrass (Lolium perenne), and red fescue (Festuca rubra). They refused to eat some other ground covers such as pachysandra (Pachysandra terminalis) and English ivy (Hedera helix). These results suggest that goose numbers at …
Incidence Of Urban Vertebrate Pest Problems In The Greater Omaha, Nebraska Area, Dennis M. Ferraro
Incidence Of Urban Vertebrate Pest Problems In The Greater Omaha, Nebraska Area, Dennis M. Ferraro
Great Plains Wildlife Damage Control Workshop Proceedings
Human interactions with wildlife and vertebrate pest species are a common occurrence in metropolitan areas. There are a number of common encounters, however, each urbanized location has unique prob-lems. Additionally, within each metropolitan area there is a gradient of encounters based on localized habitats, urban intensity, and length of urbanization. Information obtained from public inquiries directed to the Uni-versity of Nebraska-Extension in Douglas County, Nebraska were used to compile a review of these interactions in the Omaha, Nebraska metropolitan area (Table 1). Data were collected from May to December 1990. Approximately 25% of all "pest" inquiries concerned vertebrate species. In …
Current Cooperative Activities Between Aphis-Animal Damage Control And The Extension Service, Gary E. Larson
Current Cooperative Activities Between Aphis-Animal Damage Control And The Extension Service, Gary E. Larson
Great Plains Wildlife Damage Control Workshop Proceedings
The basis of our cooperation is a Memorandum of Understanding (MOU) which was signed between the Animal and Plant Health Inspection Service (APHIS) and the Extension Service (ES), both agencies of the U. S. Department of Agriculture (USDA), on May 14, 1987. The purpose of the MOU is to "establish policies and administrative arrangements for a working relationship" between the two agencies and "to provide procedures for planning, coordinating, and developing cooperative vertebrate...programs." The MOU points out that APHIS-Animal Damage Control (ADC) has responsibilities in research, operational, and technical assistance programs, which are authorized by the Animal Damage Control Act …

Great Plains Wildlife Damage Control Workshop Proceedings
I am pleased to be here with you today to discuss Animal Damage Control (ADC). I am also very pleased to see the number of ADC people attending this conference. It is an important indication of our professionalism. During the past several months, I have spoken to many of our people in ADC to challenge them to think about the future of our program. I have also spoken to many of our cooperators such as livestock organizations and resource management agencies about the same thing. This has been done in an effort to broaden our thinking about animal damage control …
Relative Effectiveness Of Repellents For Reducing Damage By Elk, William F. Andelt, Dan L. Baker, Kenneth P. Burnham
Relative Effectiveness Of Repellents For Reducing Damage By Elk, William F. Andelt, Dan L. Baker, Kenneth P. Burnham
Great Plains Wildlife Damage Control Workshop Proceedings
We tested the repellency of chicken eggs, MGK' Big Game Repellent (BGR), coyote (Canis latrans) urine, thiram, Hinder', Hot Sauce Animal Repellent' (Hot Sauce), and Ropey on captive tame elk (Cervus elaphus) in Colorado from December 1990 to February 1991. Coyote urine and BGR performed better than the other repellents for deterring elk from feeding on cubed alfalfa rations. Consumption of cubed rations treated with odor repellents increased from Day 1 through Day 5 of the trial, but consumption of thiram-treated rations decreased. During the second phase of the study, hungry elk consumed significantly more apple twigs that were treated …

I am now Vice President for Research and Education for the National Wildlife Federation (NWF)—the world's largest conservation organization. The Federation has 5.6 million members and supporters. In this position, I no longer have a small clientele of a few thousand people. In this position, hundreds of thousands of people watch NWF very closely. We have a real slice of American life in the Federation. Consequently, I have had the opportunity to see things in a broader perspective; I have been forced to broaden my horizons. What I see now causes me great concern. I see changes in the way …

Effectiveness Of Nylon Lines For Deterring Rock Doves From Landing On Ledges, William F. Andelt, Kenneth P. Burnham
Great Plains Wildlife Damage Control Workshop Proceedings
Abstract: The effectiveness of 74-kg, white, twisted nylon twine was evaluated for deterring rock doves (Columba livia) from landing on ledges at Colorado State University's Hughes Stadium in a controlled experiment during 1990. One, 2, and 3 lines were stretched 8 cm in front and 12 cm above (1 line), 8 and 18 cm above (2 lines), and 5, 12, and 18 cm above (3 lines) the ledges. The proportion of successful landings to attempted landings was reduced from 0.99 (0 lines) to 0.23 (1 line), 0.13 (2 lines), and 0.10 (3 lines). The number of pretreatment landings per ledge …

Lines To Selectively Repel House Sparrows From Backyard Feeders, Kimberly K. Kessler, Ron J. Johnson, Kent M. Eskridge
Great Plains Wildlife Damage Control Workshop Proceedings
House sparrow {Passer domesti-cus) flocks are often disliked at backyard feeding stations because they use space and food intended for other species. Monofila-ment lines, spaced 30 or 60 cm apart, have been shown to repel house sparrows from certain feeders, but responses of many back-yard bird species to lines are unknown. Three experiments were conducted at 2 sites during winter and repeated in spring using feeders with and without lines. Four pole-mounted feeders were used at each site, with an 80-cm-diameter tray on the ground below each feeder. Two feeders at each site were controls (C) without lines and 2 …
