The Use Of Fences For Predator Damage Control, Dale A. Wade Feb 1982

The Use Of Fences For Predator Damage Control, Dale A. Wade

Vertebrate Pest Conference Proceedings: 10th (1982)

The development of exclusion fencing has been extensive in Australia in attempts to reduce losses of crops and livestock to rabbits (Oryctolagus cuniculus), dingos (Canis familiaris Var. dingo) and other species. Restrictions on other damage control methods have led to increased efforts in the United States to utilize such fences for protection of crops and livestock from dogs (Canis familiaris), coyotes (Canis latrans) and other species. Electric fences have occasionally been used to protect apiaries from black bears (Ursus americanus) and to protect some wildlife species from carnivores. Varied fence types include conventional net-wire or combinations of net and barbed …

Green Chopped Bait For The Control Of The Oregon Ground Squirrel, Kenneth W. Wright Feb 1982

Green Chopped Bait For The Control Of The Oregon Ground Squirrel, Kenneth W. Wright

Vertebrate Pest Conference Proceedings: 10th (1982)

In 1972 at the Fifth Vertebrate Pest Conference, my predecessor, Loring White, described "The Adaptation to a Changing Environment of the Oregon Ground Squirrel." Today, ten years later, I will bring you up-to-date on what we are doing to control this persistent ground squirrel to a point where we can keep our farming operations going in spite of this pest. Bait-shyness or poor bait acceptance has forced us to use a green bait. For efficiency, aircraft broadcasting has become the common method of application. So that you might have a better perspective of our ground squirrel operations, I will illustrate …

Rodent Control In Barbados, Charley O. Browne Feb 1982

Rodent Control In Barbados, Charley O. Browne

Vertebrate Pest Conference Proceedings: 10th (1982)

As a result of an increase in the number of cases of the disease, leptospirosis, occurring between the years 1961 and 1971, the Government of Barbados became concerned about this health problem. With assistance from Pan American Health Organization/World Health Organization (PAHO/WHO) surveys were carried out with a hope of ascertaining the possible cause of the problem and to determine subsequent remedial action.

Changes In Bait Acceptance By Rabbits In Australia And New Zealand, A.J. Oliver, S.H. Wheeler, C.D. Gooding, J. Bell Feb 1982

Changes In Bait Acceptance By Rabbits In Australia And New Zealand, A.J. Oliver, S.H. Wheeler, C.D. Gooding, J. Bell

Vertebrate Pest Conference Proceedings: 10th (1982)

Control of rabbits, Oryctolagus cuniculus, by poisoned bait has been widely practiced in Australia and New Zealand for many years. Since the 1950s, Compound 1080 has been the active ingredient and yielded good results (ca 90% kills) when first used. Recent trails (1973-74) in New Zealand showed that the main reason for poor results obtained nowadays is the failure of many rabbits to eat bait. Recent trials in Western Australia showed that there has been a significant decline in effectiveness of rabbit control by baiting during the period 1958-1975. Shortcomings in operational technique and increased resistance to the poison 1080 …

Vertebrate Pest Management And Changing Times, Donald A. Spencer Feb 1982

Vertebrate Pest Management And Changing Times, Donald A. Spencer

Vertebrate Pest Conference Proceedings: 10th (1982)

Everywhere one turns today there are problems. The gristmills of doom and disaster are experiencing a heyday marketing this situation as one of crisis and extinction. An advantage of being an oldster in this society is that one has the perspective to recognize that these are only problems, some simple, some complex, presenting a challenge for solution to all who will lay aside their emotions and face reality. In presenting this overview of vertebrate pest management programs, I find I must dwell too frequently on "problems." This should not be interpreted as a pessimistic outlook. Sound data with professional guidance …

Dispersal And Some Implications For Control Of The California Ground Squirrel, Dennis C. Stroud Feb 1982

Dispersal And Some Implications For Control Of The California Ground Squirrel, Dennis C. Stroud

Vertebrate Pest Conference Proceedings: 10th (1982)

Data from current research and from the literature indicate that a knowledge of dispersal of the California ground squirrel can help to develop control strategy. An understanding of the rate and extent of dispersal may help reduce poor results due to patchy control. A knowledge of dispersal distance can help to determine the size of a buffer zone of control which may reduce the rate of reinvasion. The seasonal timing of dispersal is predictable in the California ground squirrel, and this can help to establish follow-up control.

A Comparison Of Selected Rodenticides For The Control Of The Common Valley Pocket Gopher (Thomomys Bottae), Barry R. Tickes, Lloyd K. Cheathem, John L. Stair Feb 1982

A Comparison Of Selected Rodenticides For The Control Of The Common Valley Pocket Gopher (Thomomys Bottae), Barry R. Tickes, Lloyd K. Cheathem, John L. Stair

Vertebrate Pest Conference Proceedings: 10th (1982)

The common valley pocket gopher (Thomomys bottae) has become a serious agricultural pest in certain regions of the Lower Colorado River Basin. The mechanical burrow-builder is the most economical and effective method of controlling this pest although many growers and some researchers have reported less-than-satisfactory results when using this technique with currently available rodenticides. Six formulations of three toxicants including strychnine, zinc phosphide and diphacinone were applied with the burrow-builder to assess their efficacy. Results indicated that negligible control is achieved with 0.35 and 0.5% strychnine although these are the most commonly used formulations in Arizona. Diphacinone also produced negligible …

Pyrotechnics For Bird Control, Geral L. Long Oct 1981

Pyrotechnics For Bird Control, Geral L. Long

Great Plains Wildlife Damage Control Workshop Proceedings

It is a little disputed fact that each year birds cause damage through crop depredation, roosting activities, and bird/aircraft strike damage with occasionally associated loss of life . Stephen (1961) cites an article by Elkins (1957) which said ducks cause millions of dollars of loss to barley, oats, and wheat crops in Canadian prairies. Damage to ripening cereal grain crops in the western United States is one of the most widespread bird problems (DeGrazio 1964). Zajanc (1962) reports these losses are estimated at $15 million annually in three western states alone where blackbirds feed in fields of rice, corn, small …

Bird-Vectored Diseases, P.M. Gough, J.W. Beyer Oct 1981

Bird-Vectored Diseases, P.M. Gough, J.W. Beyer

Great Plains Wildlife Damage Control Workshop Proceedings

Although property damage and losses can be inflicted by wild birds throughout the entire year, avian-vectored diseases of livestock are primarily a winter phenomenon in the Great Plains states. Reasons for this include the following: (1) During the winter season the birds congregate in flocks of sufficient size to be of epidemiologic significance. (2) There is a high degree of interaction between birds and livestock only when limited food induces the birds to forage among confined animals and when adverse weather forces the birds to seek shelter in housing units for livestock. (3) Colder temperatures increase the time of survival …

Tranquilizer Use In Wildlife Damage Control, Jerry Hoilien, David Oates Oct 1981

Tranquilizer Use In Wildlife Damage Control, Jerry Hoilien, David Oates

Great Plains Wildlife Damage Control Workshop Proceedings

Acceptable handling of problem or nuisance animals has been a concern of the general public and many local, state, and federal agencies. In the past, handling of these animals involved physical restraining techniques. These techniques exposed not only the "restrainer" but the "restrainee" to potential physical damage. Equipment utilizing Sucostrin as the immobilizing agent was developed to minimize these hazards.

Keynote Address - Wildlife Damage Control And The Cooperative Extension Services, James E. Miller

Great Plains Wildlife Damage Control Workshop Proceedings

Since the establishment of the Extension Service within the United States Department of Agriculture in 1914, in accordance with the mandate of the Smith-Lever Act, Extension personnel have recognized the need and responsibility to provide educational programs to assist clientele both rural and urban. These programs from the "grass roots" level to the Federal level are based on the "long established premise that assisting people with factual, effective and practical educational programs to help them solve problems, evaluate alternatives and make objective decisions, would provide these people with information that would enable them to help themselves. Wildlife damage control was …

Efficacy And Costs Of Four Rodenticides For Controlling Columbian Ground Squirrels In Western Montana, Steven W. Albert, C. Raymond Record Oct 1981

Efficacy And Costs Of Four Rodenticides For Controlling Columbian Ground Squirrels In Western Montana, Steven W. Albert, C. Raymond Record

Great Plains Wildlife Damage Control Workshop Proceedings

Efficacy and costs of four rodenticides for the control of Columbian ground squirrels were compared in western Montana. Reductions in surface ground squirrel activity and costs per 100 burrows treated for the various treatments were: 1080 oat groats 99.6%-$3.11, gas cartridges 72.2%-$26.57, strychnine oats 64.2%-$3.06, zinc phosphide cabbage 60.9%-$8.48, zinc phosphide oats 41.3%-$3.15, and strychnine cabbage 14.4%-$9.58. Surface deaths associated with 1080 amounted to 2.35 ground squirrels per 100 burrows treated. Above ground death rates for the remaining treatments were negligible or nonexistent for both target and non-target species. One white-footed deer mouse was found dead on the strychnine cabbage …

Criteria For Pesticide Registration, John R. Beck, William B. Jackson Oct 1981

Criteria For Pesticide Registration, John R. Beck, William B. Jackson

Great Plains Wildlife Damage Control Workshop Proceedings

Satisfactory criteria for registration of vertebrate pesticides, other than for commensal rodents, are largely lacking. Even those that are available have not made their way fully through the bureaucratic processes of EPA. Recognizing the difficulty of standardizing pesticide registration, EPA in 1973 requested that the American Society for Testing and Materials (ASTM) consider establishing a committee on pesticides for the purpose of writing consensus standards, guidelines, and practice statements. The resulting committee of more than 400 biological scientists and chemists from academia, industry, and regulatory agencies has prepared standards on many phylogenetic areas.

Urban Vertebrate Pest Management: A Practical Approach, Patricia A. Chamberlain, Milton Caroline, William A. Wright Oct 1981

Urban Vertebrate Pest Management: A Practical Approach, Patricia A. Chamberlain, Milton Caroline, William A. Wright

Great Plains Wildlife Damage Control Workshop Proceedings

Urban vertebrate pest management is influenced by a variety of factors. Public perceptions of wildlife limit control specialists in their methods of operation. Population density, costs of operation and timing of control are considered. Suggestions are made for operational mode, methods, baits, traps and disposal. Two new trapping concepts are described and experimental data on attractants are given. Computer-summarized data on urban wild life conflicts from one state (Texas) show that most complaints can be handled by extension methods supplemented with direct control by the public and wild life damage control specialists.

U.S. Fish And Wildlife Service Coyote Control Research, Guy Connolly Oct 1981

U.S. Fish And Wildlife Service Coyote Control Research, Guy Connolly

Great Plains Wildlife Damage Control Workshop Proceedings

This paper reviews recent research by the Denver Wildlife Research Center, Section of Predator Management Research, on chemical and lethal coyote control methods. Steel trap modifications, aerial shooting, den hunting, the M-44 (spring-loaded sodium cyanide ejector), toxic and nontoxic baits, the toxic collar, other livestock-borne toxicants, development of new toxicants, and aversive conditioning with lithium chloride are discussed. No new, lethal coyote control method has been implemented into practical use over the past decade, but toxic baits and den hunting were lost or banned from use in the Federal-Cooperative Animal Damage Control Program. One new technique, the toxic collar, may …

Prairie Dog Dispersal In Wind Cave National Park: Possibilities For Control, Monte G. Garrett, William L. Franklin Oct 1981

Prairie Dog Dispersal In Wind Cave National Park: Possibilities For Control, Monte G. Garrett, William L. Franklin

Great Plains Wildlife Damage Control Workshop Proceedings

A study was conducted in Wind Cave National Park, South Dakota, to collect basic information on black-tailed prairie dog (Cynomys ludovicianus) dispersal and to test alternative control techniques. Dispersal occurred during a limited time period in late spring, involved both male and female prairie dogs, and resulted in relatively short movements and poor survivorship. The use of artificial visual barriers to inhibit colony expansion was effective but difficult to apply. The use of diethylstilbestrol as a temporary anti-fertility agent was shown to be an easy and effective method to reduce prairie dog reproduction and decrease colony expansion.

Animal Damage Control - Now And In The Future, James F. Gillett

Great Plains Wildlife Damage Control Workshop Proceedings

I am pleased to have the opportunity to speak to you today on behalf of the Department of the Interior's Fish and Wildlife Service. I believe animal damage control is an element of a comprehensive wild life management program. It deals with population dynamics, mortality factors, and other management considerations. It is one of a variety of challenges faced by all wildlife managers regardless of whether they are dealing with big game, waterfowl, or even endangered species. Some question the role of, or need for, intensive management of wildlife populations in favor of a "let nature take its course" approach. …

Ipm - An Overview, R.E. Gold Oct 1981

Ipm - An Overview, R.E. Gold

Great Plains Wildlife Damage Control Workshop Proceedings

Integrated Pest Management (IPM) is a term that is widely used, but little understood. The Federal Interagency IPM Coordinating Committee adopted the description of IPM as "a systems approach to reduce pest damage to tolerable levels through a variety of techniques, including predators and parasites, genetically resistant hosts, natural environmental modifications and, when necessary and appropriate, chemical pesticides." Essentially, the ultimate goal of IPM programs is to reduce pest populations to "tolerable levels". This may be a departure from more traditional approaches to pest control that advocated the elimination or eradication of pest populations. Another postulate of IPM is that …

Reducing Coyote Damage To Sheep With Non-Lethal Techniques, Jeffrey S. Green Oct 1981

Reducing Coyote Damage To Sheep With Non-Lethal Techniques, Jeffrey S. Green

Great Plains Wildlife Damage Control Workshop Proceedings

Since 1972, when the U.S. Government restricted uses of toxicants for controlling coyotes, a variety of non-lethal techniques has been tested for effectiveness in protecting livestock. Some were ineffective, but others helped to reduce the incidence of predation on sheep. In addition to sound management practices, electric fencing and livestock guarding dogs appear to have the widest applicability for sheep producers. Mechanical frightening devices have been successful in some fenced pasture sheep operations. As with the lethal methods currently used, non-lethal control does not solve all depredation problems. A combination of various control techniques (both lethal and non-lethal) is necessary …

Controlling Problem Pocket Gophers And Moles, F. Robert Henderson

Great Plains Wildlife Damage Control Workshop Proceedings

Two small mammals, pocket gophers and moles, spend most of their lives underground and can cause a lot of concern and frustration to people above ground. The pocket gopher and mole, while engaging in their daily activities, leave their telltale marks on lawns and gardens, on golf courses, parks, cemeteries, and on alfalfa fields and rangelands. Sometimes they damage irrigation canals and dikes and chew into underground cables. They can also create root damage to young trees.

Prairie Dogs And Their Influence On Rangeland And Livestock, Robert M. Hyde Oct 1981

Prairie Dogs And Their Influence On Rangeland And Livestock, Robert M. Hyde

Great Plains Wildlife Damage Control Workshop Proceedings

The prairie dog (Cynomys) has been cussed, discussed, protected, exploited, credited with doing many good things and accused of being completely bad. He is at least a controversial Great Plains inhabitant. The prairie dog has been credited with adding significant amounts of organic matter to the soil profile through burrowing, clipping and feces deposition. Really the 35 to 40 pounds of organic matter per acre per year added to the soil profile by prairie dogs is rather insignificant especially when one considers that amount throughout a 5 to 7 foot soil profile and that the organic matter added isn't well …
