L:Egal Problems Of Bird Damage Control - Protected Species And Practical Solutions, Ronald D. Ogden Oct 1981

L:Egal Problems Of Bird Damage Control - Protected Species And Practical Solutions, Ronald D. Ogden

Great Plains Wildlife Damage Control Workshop Proceedings

Legal problems in bird damage control can occur from two directions. First, most birds are protected by federal law; all birds are protected by some states and all birds can be protected by local governing agencies. Second, the method of control may be restricted by state or local governments. Some states require permits to use toxicants; shooting is prohibited in some areas by local government. The only practical solution is to know the federal and state regulations pertaining to each individual project and to check each time with local agencies for further restrictions. A federal permit is required to trap …

Computers And Vertebrate Pest Control, Terrell P. Salmon, Dennis C. Stroud, Aileen Kennedy Oct 1981

Computers And Vertebrate Pest Control, Terrell P. Salmon, Dennis C. Stroud, Aileen Kennedy

Great Plains Wildlife Damage Control Workshop Proceedings

Computers are affordable and usable by most individuals involved in vertebrate pest control. Their value as a research tool for vertebrate pest population modeling has been proposed; however, few, if any, are being used for field operations. Despite their ecological limitations, simulating models have been developed that are useful in wildlife management, including wildlife pest problems. Improvement of these or similar models could answer questions such as population effects from a control program, proper timing of control, and the impact of control on non-target species. Vertebrate pest control information can also be stored, retrieved and disseminated via the computer. The …

A Vertebrate Ipm Project In Nebraska, Robert M. Timm Oct 1981

A Vertebrate Ipm Project In Nebraska, Robert M. Timm

Great Plains Wildlife Damage Control Workshop Proceedings

An Integrated Pest Management project in Nebraska is assisting farmers, particularly pork producers, in controlling damage caused by Norway rats, house mice, house sparrows, and starlings. This extension program also provides information on control of pocket gophers in alfalfa and on rangelands. Integrated control recommendations include rodent- and bird-proof construction, limitation of food and shelter, traps, and toxicants (rodenticides and avicides). The project is attempting to gather data on economic damage, including structural damage to confinement buildings, caused by these pests. This information will be used to assist producers in deciding when to initiate control.

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 …

A Review Of Prairie Dog Diet And Its Variability Among Animals And Colonies, Kathleen A. Fagerstone Oct 1981

A Review Of Prairie Dog Diet And Its Variability Among Animals And Colonies, Kathleen A. Fagerstone

Great Plains Wildlife Damage Control Workshop Proceedings

After almost 70 years of decline, prairie dog numbers are increasing in many western states. As populations expand, it becomes increasingly important to clarify the degree of competition between prairie dogs and livestock. A review of studies on prairie dog food habits shows variable results. Prairie dogs frequently eat the same plant species as cattle and their activities may cause a decrease in grasses normally considered good livestock forage and an increase in forb cover. However, in some instances, prairie dogs may be beneficial to rangeland; plant species diversity and protein content of forage are often greater on prairie dog …

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.

Controlling Problem Pocket Gophers And Moles, F. Robert Henderson Oct 1981

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 …

Usda And Animal Damage Control, James O. Lee Jr.

Great Plains Wildlife Damage Control Workshop Proceedings

I appreciate the opportunity to appear before your group to express the views of the Department of Agriculture concerning animal damage control. The Department of Agriculture strongly supports and recognizes the need for immediate animal damage control to reduce livestock losses. It sees the need for—and supports--an animal damage control program that both uses existing methods and develops new and more selective ones and, at the same time, protects the environment.

Prairie Dog Density And Cattle Grazing Relationships, Daniel W. Uresk, James G. Maccracken, Ardell J. Bjugstad

Great Plains Wildlife Damage Control Workshop Proceedings

Blacktail prairie dogs (Cynomys ludovicianus) were more abundant (P < 0.01) in areas of southwestern South Dakota heavily grazed by cattle than in areas where cattle were excluded. Results suggest that periodic exclusions or reduced cattle stocking rates, in combination with control programs, help regulate prairie dog population increase and expansion as indexed by burrow counts.

A Common Sense Approach To Commensal Rodent Control, Edward F. Marshall Oct 1981

A Common Sense Approach To Commensal Rodent Control, Edward F. Marshall

Great Plains Wildlife Damage Control Workshop Proceedings

More than once the phrase has been heard, "I don't know what's in your bait, I don't have time to read the label, but it sure does work good." To be quite frank, a pest control operator (PCO) or for that matter, any pesticide user cannot afford not to read and understand pesticide labels. Commensal rodent control has been practiced for centuries, utilizing a variety of devices and poisons. However, in the last three decades new toxicants and bait forms have been developed, but are not fully understood. It is of great importance that first we take a common sense …

Management Of Black-Tailed Prairie Dogs On The National Grasslands, Greg L. Schenbeck Oct 1981

Management Of Black-Tailed Prairie Dogs On The National Grasslands, Greg L. Schenbeck

Great Plains Wildlife Damage Control Workshop Proceedings

Black-tailed prairie dogs (Cynomys ludovicianus) occupy approximately 22,800 ha on 11 National Grasslands in the West. Prairie dog control has been implemented on 5 National Grasslands and is planned for 1 additional National Grassland. A unique prairie dog management program in the Conata Basin area of the Buffalo Gap National Grassland is highlighted in this report. Conata Basin is a major prairie dog area and attempts are being made to control prairie dogs while trying to maintain habitat for the black-footed ferret (Mustela nigripes). Repopulation of treated colonies has been a major and costly problem in Conata Basin, and it …

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.

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.

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. …

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 …

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.
