Pred-X Field Test Results, R.A. Field, J.E. Nel Dec 1993

Pred-X Field Test Results, R.A. Field, J.E. Nel

Great Plains Wildlife Damage Control Workshop Proceedings

During the spring and summer of 1992, a number of sheep producers used Pred-X ear tags to guard against predation by coyotes. We were able to contact 20 of these producers through the help of the Wyoming Wool Growers Association, county agents and companies who sold the tags. Sheep producers in other states also used the tags and we were able to contact 21 of these producers through the cooperation of the American Sheep Industry Association whose representatives printed a short letter and a survey form in the October 1992 National Wool Grower Magazine. Phone calls were made to many …

Food Preferences Of Common Grackles, Red-Winged Blackbirds, And Yellow-Headed Blackbirds Presented With Cracked Corn, Sunflower Meats, And Brown Rice, Laura A. Mendoza, George M. Linz, David L. Bergman, William J. Bleier

Great Plains Wildlife Damage Control Workshop Proceedings

Blackbirds migrating through North Dakota in late summer damage sunflower crops shortly after the yellow ray petals begin to wither and fall (Besser 1985). DeHaven (1982) reported bird damage losses of $7.4 million on 2.2 million acres in 1980. Various behavioral, chemical, and mechanical strategies have been employed over the past decade to reduce the damage. Although some of these methods have effectively dispersed or reduced blackbird populations, many have proven to be ineffective over time, economically infeasible, or culturally unacceptable (Guarino 1984).

Update On Development Of A Tranquilizer Trap Device, Peter J. Savarie, Kathleen A. Fagerstone, Edward W. Schafer Jr.

Great Plains Wildlife Damage Control Workshop Proceedings

The foothold trap is an important tool that is used by the U.S. Department of Agriculture Animal Damage Control (ADC) program to capture coyotes (Canis latrans) that are causing livestock depredations. In FY 1990 and FY 1991 the ADC program trapped 17,732 and 15,805 coyotes, respectively (USDA 1991;1992). Foothold traps can cause trauma and injury to feet and legs (Englund 1982; Linhart et al. 1986; Olsen et al. 1986, 1988; Onderka et al. 1990, Tullar 1984) and Onderka et al. (1990) observed oral injuries such as broken teeth, and tongue and gum lacerations in captured animals. The ADC program and …

Lyme Disease: Incidence And Prevention, With Emphasis On Wildlife Biologists, Robert M. Timor, Robert S. Lane Dec 1993

Lyme Disease: Incidence And Prevention, With Emphasis On Wildlife Biologists, Robert M. Timor, Robert S. Lane

Great Plains Wildlife Damage Control Workshop Proceedings

Lyme disease, a potentially debilitating illness in humans if untreated, is caused by the spirochete Bonrelia burgdorferi. First recognized in the mid-1970s in Lyme, Connecticut, the disease has been reported in at least 46 of the United States and in Canada, Australia, Asia, and Europe. This disease is primarily transmitted to humans by tick bite. In California, the tick believed primarily responsible is the western black-legged tick, Nodes pacificus In the upper midwestern and northeastern states, the usual vector is Nodes scapularis (formerly I_. ammini in part).

Rejex-It'" Ag-36 The Gentle Way To Repel Geese From Golf Courses And Other Turf Areas, Peter F. Vogt

Great Plains Wildlife Damage Control Workshop Proceedings

Birds have always been a problem in agriculture, specially for berries and fruits. Farmers and home owners have been fighting these problems with limited success for centuries. However, the problems with birds on turf are relatively new and are not even known by many people. The "Complete Guide to Pest Control" (Ware 1988) does not even mention geese as a pest, or golf courses as an area of bird problems.

Methyl Anduanilate Formulations To Repel Birds From Water At Airports And Food At Landfills, Richard A. Dolbeer, Jerrold L. Belant, Larry Clark

Great Plains Wildlife Damage Control Workshop Proceedings

Bird strikes to aircraft are of increasing concern to the aviation community (BSCE 1990). One factor contributing to strikes is that gulls and other bird species often flock to temporary pools of fresh water at airports after heavy rains (Blokpoel 1976). Another factor is the location of waste disposal facilities near airports which gulls and other bird species use as a food source (Burger and Gochfeld 1983, Greig et al. 1986). The U.S. Federal Aviation Administration issued Order 5200.5 in 1974 to prohibit waste disposal sites within 10,000 ft (3,000 m) of runways used by turbine-powered aircraft. This order was …

Field Evaluation Of Three Strychnine Concentrations For Controlling Townsend's Pocket Gophers, George H. Matschke, Geraldine R. Mccann, Heather W. Krupa, John O'Brien Dec 1993

Field Evaluation Of Three Strychnine Concentrations For Controlling Townsend's Pocket Gophers, George H. Matschke, Geraldine R. Mccann, Heather W. Krupa, John O'Brien

Great Plains Wildlife Damage Control Workshop Proceedings

Among requirements for the reregistration of strychnine, the Environmental Protection Agency (EPA) requires efficacy data from strychnine paste-alfalfa baits prepared with strychnine alkaloid paste (NV 830009). The EPA reviewed the data originally submitted by the state of Nevada for registering this strychnine alkaloid paste label and determined that more field efficacy data were needed to maintain the current registration. Therefore, additional efficacy data for strychnine paste-alfalfa baits on Townsend's pocket gopher (Thomomys townsendi) was requested from the state of Nevada.

The Prairie Dog Ecosystems And Endangered Species, Daniel W. Mulhern, Kenneth L. Powell Dec 1993

The Prairie Dog Ecosystems And Endangered Species, Daniel W. Mulhern, Kenneth L. Powell

Great Plains Wildlife Damage Control Workshop Proceedings

The prairie dog is no doubt one of the most controversial animals in the western United States. Public sentiment regarding this rodent runs the gamut from some livestock producers who are satisfied only with complete eradication of all prairie dogs, and some animal rights groups who would like to see all prairie dogs given complete protection from any form of harm. Between these two extremes lie the real truths surrounding this sometimes destructive, mostly biologically beneficial, creature.

The Evolutionary Relationships Of The Skunks To Each Other And The Rest Of The Weasels; With A Note On Behavioral Idiosyncrasies, Jerry W. Dragoo Dec 1993

The Evolutionary Relationships Of The Skunks To Each Other And The Rest Of The Weasels; With A Note On Behavioral Idiosyncrasies, Jerry W. Dragoo

Great Plains Wildlife Damage Control Workshop Proceedings

I will discuss four aspects of my current research with respect to skunks. The first concerns the recognition and conservation of potentially endangered populations of hog-nosed skunks. The second pertains to the evolutionary relationships among the three genera of skunks, based on genetic data. The third aspect also is based on molecular data, and is a study of the relationship of the skunks to the rest of the Mustelidae (weasels). Finally, I will discuss some of the behavioral idiosyncrasies I have observed in my endeavors to obtain skunk specimens.

Are Farmer And The Environment Natural Enemies Like The Sheep And The Coyote?, B.L. Flinchbaugh Ph.D. Dec 1993

Are Farmer And The Environment Natural Enemies Like The Sheep And The Coyote?, B.L. Flinchbaugh Ph.D.

Great Plains Wildlife Damage Control Workshop Proceedings

Agricultural policy historically has been price and income policy for commercial farmers. Price supports, land retirement, stored reserves and deficiency payments have been the backbone of farm bills since Roosevelt's AAA (Agriculture Adjustment Act). Preservation of the family farm was the goal, along with an abundant supply of high quality food at reasonable prices, to convince the consumer that commercial agriculture policy was in their "best interests."

Prospects For The Future In Animal Damage Control, Donald Hawthorne Dec 1993

Prospects For The Future In Animal Damage Control, Donald Hawthorne

Great Plains Wildlife Damage Control Workshop Proceedings

I am pleased to be here to address a subject that is very special to many of us, one to which I have devoted my entire career. Animal damage control is a controversial component of wildlife management. In the late 1960's and early 70's, many wildlife practitioners tried to divorce themselves from animal damage control activities. In recent years, however, management of wildlife damage is viewed by many as a vital and integral part of wildlife management, whether to protect human interests and safety or to save an endangered species.

Prairie Vole Damage Control In No-Till Corn And Soybean, Ron A. Hines Dec 1993

Prairie Vole Damage Control In No-Till Corn And Soybean, Ron A. Hines

Great Plains Wildlife Damage Control Workshop Proceedings

The prairie vole (Microtus ochragaster) is the primary rodent that reduces no-till crop plant stands in Southern Illinois. Because the vole requires a full canopy cover for protection from predators, established grass or legume sod fields and field borders (including wheat or rye stubble, set-aside and cover crop seedings) provide an ideal habitat for the development of a very high population of this rodent. In fields that have had the vegetative cover maintained for more than one year prior to planting no-till corn, plant stand reductions can reach 80 to 100 percent in intense (more than 30 per …

An Evaluation Of Laminated Offset Jawed Traps For Reducing Injuries To Coyotes, John M. Houben, Merrilee Holland, Sherman W. Jack, Carolyn R. Boyle Dec 1993

An Evaluation Of Laminated Offset Jawed Traps For Reducing Injuries To Coyotes, John M. Houben, Merrilee Holland, Sherman W. Jack, Carolyn R. Boyle

Great Plains Wildlife Damage Control Workshop Proceedings

Increasing public concern about injuries caused by foothold traps has resulted in a considerable amount of research for more humane traps. Much of this research effort has focused on evaluating the Victor No. 3 Soft-Catch trap manufactured by Woodstream Corporation, Lititz, Pennsylvania (Linhart and Dasch 1992). Research has concentrated on two major areas: (1) efficiency and selectivity of different trap types and modifications used for capturing coyotes (Canis latrans) and (2) reducing animal injuries associated with trapping (Phillips and Mullis 1991). The Soft-Catch trap has been shown to reduce foot injury sustained by most captured furbearers (Tullar 1984, Olsen et …

Future Extension Programs On Wildlife Damage Management, James E. Miller Dec 1993

Future Extension Programs On Wildlife Damage Management, James E. Miller

Great Plains Wildlife Damage Control Workshop Proceedings

Extension educational programs, in cooperation with other federal and state organizations, significantly contribute to the present status of wildlife damage management as understood by natural resources professionals and the interested public. Although Extension Service, USDA provides national leadership and coordination of programs, most of the effective programs originate at the state and local level Cooperative Extension Service, regardless of the subject matter. This is particularly true in the area of wildlife damage management. For example, a recent compilation of Extension publications and videotapes on wildlife damage management identifies well over 100 titles available throughout the CES System (Ruff, Craven and …

Wildlife Damge And The Iowa Farmer. The Influence Of Perspective, James L. Pease Ph.D. Dec 1993

Wildlife Damge And The Iowa Farmer. The Influence Of Perspective, James L. Pease Ph.D.

Great Plains Wildlife Damage Control Workshop Proceedings

Over 90% of Iowa's land base is privately owned and managed for agriculture. Less than 2% is publicly-owned and managed specifically for wildlife. Thus, virtually all of Iowa's 36 million acres (14.8 million hectares) has been altered. Some 70% of the forests have been lost, over 95% of the wetlands drained, and over 99.9% of the native prairies have been converted to agricultural, transportation, or other human uses. Such extensive alteration of habitats encourages the wildlife species that are ecological generalists to flourish. These species are also those that are most likely to come into conflict with humans, competing with …

The Impact Of European Community's Humane Trapping Resolution On U.S. Wildlife Damage Control Program, Mahadev Bhat, Robert Gotie, Luther Keller Dec 1993

The Impact Of European Community's Humane Trapping Resolution On U.S. Wildlife Damage Control Program, Mahadev Bhat, Robert Gotie, Luther Keller

Great Plains Wildlife Damage Control Workshop Proceedings

This paper discusses the implications that The European Economic Community's recent Wild Fur Regulation (WFR) might have on the U.S. wildlife damage control program. Beginning Jan. 1, 1995, the regulation will ban fur imports originating from countries which fail to (1) stop foothold trapping, and (2) adopt international humane trapping standards. Countries which pledge to adopt humane trapping standards will be granted a one-year extension to comply with the WFR. Because the European community is an important market for American furs, the regulation will affect the trapping of many American fur-bearing species, including raccoon, beaver, bobcat, muskrat, coyote, otter, badger, …
