A Decade Of Usda-Ars Predator Research, 1972-1982, Jeffrey S. Green

Great Plains Wildlife Damage Control Workshop Proceedings

Federal government restrictions in 1972 on several widely-used forms of predator control stimulated research on alternative methods of reducing depredation on livestock. In the same year, the U.S. Department of Agriculture began predator research through the Agricultural Research Service (ARS) and designed the U.S. Sheep Experiment Station CUSSES, near Dubois in southeastern Idaho as the principle location for the investigations. At the outset, the objective of ARS research was to examine non-lethal methods for reducing depredation, primarily by coyotes (Cants), on sheep. During the first several years, while predator research facilities were constructed at the USSES, ARS funds were primarily …

Keeping Squirrels And Roof Rats Out Of Structures, Jonathan W. Linn

Great Plains Wildlife Damage Control Workshop Proceedings

component of any total pest control program. There are many species of rodents that enter buildings, usually for the purpose of shelter and/or food. They may enter in the fall to survive the winter weather, or in the spring to have a safe place to give birth to their young. Much has been written about rodent-proofing buildings to keep out both native and introduced rats and mice. This article will try and cover methods that can be used to keep out our native squirrels, which include the eastern gray squirrel (Sciurus carolinensis), the western gray squirrel (Sciurus griseus), the eastern …

Current Events In Extension Wildlife Damage Control In The United States, James E. Miller

Great Plains Wildlife Damage Control Workshop Proceedings

The Cooperative Extension Services (CES) within each state and territory of the United States and their federal partner, the Extension Service, United States Department of Agriculture (USDA), have long recognized the need for, and responsibility of, providing educational programs in wildlife damage control to both rural and urban clientele. The system employed to implement these educational programs was established early in this century dating back to passage of the Smith-Lever Act in 1914. Through the years since that time, the strengths of this system have been the recognition of the need for a continuing spirit of cooperation with other federal …

Use Of Aluminum Phosphide Fumigants For Burrowing Rodent Control, Carl Snider

Great Plains Wildlife Damage Control Workshop Proceedings

This article is to inform you about aluminum phosphide, a new burrowing rodent fumigant. The history of aluminum phosphide is long, dating back to the mid-1930'x, but the first aluminum phosphide preparation was not introduced into the United States until 1955. The traditional usage of phosphine throughout the USA has been in the grain and food industry in fumigating raw agricultural commodities, processed foods, animal feed, stored tobacco, and certain non-agricultural commodities. Aluminum phosphide was not approved in the U.S. for burrowing rodents until 1981.

An Evaluation Of Burrow Destruction As A Ground Squirrel Control Method, Dennis C. Stroud

Great Plains Wildlife Damage Control Workshop Proceedings

Several researchers have suggested that the presence of burrows is a limiting factor for ground squirrel populations and that the destruction of these burrow systems can reduce the rate of reinvasion following control. However, no one has yet tested the potential value of burrow destruction as a control method.

Keynote Address, Robert J. Pool

Great Plains Wildlife Damage Control Workshop Proceedings

Most modern environmentalists during their formative years have had little actual contact with wildlife under natural conditions. Their wildlife philosophies have been developed via the mass media and from experiences with animals as pets or confined in zoos. In general, modern environmentalists are sincere, dedicated, idealistic and enthusiastic, but they often lack realism and are blessed with the innocence of naivete. The majority of people in the United States now exhibit strong affection for wild animals and are deeply concerned over any actions perceived as causing pain to individual animals. These attitudes towards wild animals will impact on future wildlife …

Behavioral Ecology Of Coyotes: Implications For Reducing Predator-Livestock Conflicts, William F. Andelt

Great Plains Wildlife Damage Control Workshop Proceedings

During the past 2 decades, numerous research projects have been conducted to gain a better understanding of coyote (Canis latrans) behavior and ecology which could be used to reduce livestock losses to predators. This paper synthesizes some of these investigations to provide some insight into methods of reducing livestock losses to coyotes.

Fencing For Deer Control, William R. Bonwell

Great Plains Wildlife Damage Control Workshop Proceedings

Deer (odocoileus virginianus) depredations are a serious problem for many landowners and few landowners plan for these potential depredations. Fencing to restrict deer movements has become the most economical means of control. Several fence designs are available but the new electrified high tensile wire fences hold the most promise for deer control.

Wildlife Damage Control Problems And Concerns Of State Wildlife Agencies, F. Robert Henderson

Great Plains Wildlife Damage Control Workshop Proceedings

Wildlife damage seems to be a greater concern today than 10 years ago. Controlling wildlife damage is a complex issue and the responsibility for its accomplishment has been given to diverse groups of private, local, county, state and federal entities. The types of programs vary from state to state, and often within a state several different programs are conducted by different agencies. It is the purpose of this paper to attempt to present information on the concerns of the state wildlife agencies regarding wildlife damage problems.

Some International Approaches To Rat Control, Walter E. Howard

Great Plains Wildlife Damage Control Workshop Proceedings

There are many basic requirements concerning the political structure, financial support needed, proper organization, staff training, public education, laws and regulations, and the keeping of good records, which must be adequately considered before a rat control program can become successful. Likewise, there are also a number of basic principles concerning rodent control that must be understood and adhered to. Some villages in Korea and the country of Kuwait will be used as examples of new rat control approaches.

The Use Of Ultralight Aircraft For Aerial Control Of Coyotes, James E. Knight

Great Plains Wildlife Damage Control Workshop Proceedings

The changing complexion of modern animal damage control, coupled with the lack of funding available to government, has created the need for innovative methods of conducting control programs. Ultralight aircraft are presently being tested to determine their effectiveness, efficiency and safety for aerial gunning coyotes.

Rancher Use Of Compound 1080 Toxic Collars In New Mexico, Gary A. Littauer

Great Plains Wildlife Damage Control Workshop Proceedings

Twenty-three ranchers were trained and certified to use Compound 1080 in toxic collars to control coyote ( Ca nts l a tran s predation on sheep during a 2-year experimental program conducted by the New Mexico Department of Agriculture. Fifteen ranchers employed a total of 330 collars in field use. Two used collars in preventive control schemes and success was unknown. Thirteen used collars in corrective control (i.e. predation was in progress); 6 had collared lambs attacked and killed by coyotes; 4 had 1 or more collars punctured by coyotes and in 1 case a bobcat; 3 solved specific coyote …

The Viability Of Rabies In Carrion, Joseph M. Schaefer

Great Plains Wildlife Damage Control Workshop Proceedings

The viability of rabies virus in carrion is a major factor in affecting the chances that a scavenging animal could contact the disease. The purpose of this study was to determine the viability of rabies virus in brains and salivary glands of rabid striped skunk (Mephitis mephitis ) carcasses exposed to different controlled temperatures.

Workshop-Discussion Session, Joesph M. Schaefer

Great Plains Wildlife Damage Control Workshop Proceedings

The purpose of the workshop-discussion session was to establish a list of ideas that would provide the best focus and direction to improve wildlife damage control programs. During this session the Nominal Group Technique (NGT) (Delbecq et al. 1975) was used to: 1) identify and rank obstacles that limit the effectiveness of wildlife damage control efforts, and 2) generate possible solutions to the most important obstacles. This format allowed equal and full participation and was successful in generating many original ideas.

Reducing Goat Losses To Predators: Past Vs. Present Producers In Texas, Jerry H. Scrivner

Great Plains Wildlife Damage Control Workshop Proceedings

The purpose of this study was to gather information regarding the application and economic implications of predator control and husbandry methods used by 104 past and 103 present Angora goat producers in Texas. Of 7 techniques [(1) predator control by ranchers, (2) support of private or government trappers, (3) night penning of livestock, (4) confinement or semi-confinement kidding, (5) extra checking on goats, (6) the use of guard dogs, and (7) the use of scare devices] ranchers use to reduce predation losses, present producers used significantly more techniques than did past producers. Also, present producers generally implemented each technique to …

Rodent Populations And Crop Damage In Minimum Tillage Corn Fields, Richard E. Young, William R. Clark

Great Plains Wildlife Damage Control Workshop Proceedings

No-till and disked cornfields were examined in southwest Iowa to determine small mammal population densities, movements, and impacts of rodent depredations on corn seedlings. Two replicates of the treatments corn planted into. corn stubble, corn planted into chemically treated sod, and corn planted into spring-disked fields were studied during the 1982 and 1983 growing seasons. Grids of 100 Sherman live traps were established at the edge and middle of each field to determine rodent densities and document possible encroachment of small mammals from nearby habitats. Trapping experiments were conducted for 6 consecutive days during May, August, and November. To assess …

Population Reduction Of Richardson's Ground Squirrels Using A Brodifacoum Bait, George H. Matschke, Steve F. Baril, Raymond W. Blaskiewicz

Great Plains Wildlife Damage Control Workshop Proceedings

On 6 study plots (3 treated and 3 control of 2.47. acres--1 ha), we evaluated the efficacy of a 50 ppm brodifacoum grain bait on Richardson's ground squirrels (spermophilus richardsonii Efficacy was measured by 3 methods: (1) radio-telemetry - 22 ground squirrels were live trapped on each treated plot and equipped with radio transmitters, (2) mark-recapture - by mark-recapture sampling methods and the computer program entitled CAPTURE, and (3) Tanaka's formula - by using only marked survivors retrapped posttreatment. Treatment began the day following the pretreatment trapping period by systematically baiting each burrow entrance with approximately 16-19 g of bait. …

As one of the people who perceived the need for this conference in the early 1950’s, …

The Microcomputer And Kansas Wildlife Damage Reports, Martin Ottenheimer

Great Plains Wildlife Damage Control Workshop Proceedings

When F. Robert Henderson, the Extension State Leader of Kansas' Wildlife Damage Control Program, asked me for assistance in setting up a microcomputer system that would enable him to organize and analyze wildlife damage reports, I was surprised. "Certainly," I thought, "it's not because I am a social anthropologist and in my travels around the world I deal with some pretty wild life" No, Bob knew about my work with microcomputers in Anthropology and since we have been friends for some years he also knew that I would talk with him about the problems in using microcomputers. He also knew …

Guardian Dog Research In The U.S., John C. Mcgrew

Great Plains Wildlife Damage Control Workshop Proceedings

Research on the use and effectiveness of guardian dogs has been conducted since 1977 at 3 locations in the U.S.: the Livestock Dog Project (Amherst, MA), the U.S. Sheep Experiment Station (Dubois, ID), and Colorado State University (Ft. Collins). Their findings are quite consistent: dogs guard sheep and goats directly, i.e., they respond aggressively to predators, chasing them away when necessary, then returning to the flock. This aggressive response toward predators is apparently defense of personal space rather than territorial defense. The development of attentiveness toward sheep, beginning early in life, is probably the most important aspect of training a …

A Mississippi Kite In Hall County, Nebraska, Gary Lingle, Kari L. Haugh, Lee Morris, Babs Padelford, Loren Padelford

Nebraska Bird Review

The Mississippi Kite (lctinia mississippiensis) is considered extremely rare in Nebraska, with only 8 spring records and 2 fall records (Johnsgard, P.A., 1980, A revised list of the birds of Nebraska and adjacent Plains States, Occasional papers of the N.O.U., No.6, Lincoln, Nebraska, 114 pp.). On 10 July 1983, at 12:30 CDT, we sighted an adult Mississippi Kite circling above a flooded native hay meadow on Shoemaker Island, Hall Co. (Sec. 1, T9N R11W). The bird was identified by its frosted head and secondaries, pearly gray back and underside, and black retrices. It is believed this Kite was …
