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 …

The Potential Dollar Value Of Tree Loss In Orchards, George W. J. Laidlaw

Great Plains Wildlife Damage Control Workshop Proceedings

Rising costs have increased the need to re-evaluate the attributes which influence profit or lack of it . People are no longer willing to accept loss when cost-benefit information allows the farmer or orchardman to appreciate the repercussions associated with mismanagement.

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

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

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 …

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 …

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

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.

Status Of The Environmental Protection Agency's Review Of Rodenticides, William C. Dickinson

Great Plains Wildlife Damage Control Workshop Proceedings

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. …

Use Of Starlicide To Reduce Starling Damage At Livestock Feeding Operations, James F. Glahn

Great Plains Wildlife Damage Control Workshop Proceedings

Starling damage at livestock feedlots is discussed and background information is given on the properties of Starlicide® which need to be considered when using this product for control of starlings. A five-step guideline for a starling control program with Starlicide is presented: pre-treatment assessment, collecting information and materials, pre-baiting, baiting strategies with bait containers and broadcast application methods, and post-treatment assessment.

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.

Nebraska's Animal Damage Control Program, Robert P. Kelly

Great Plains Wildlife Damage Control Workshop Proceedings

Nebraska has had an animal damage control program of some sort for at least 40 years that we are able to determine. In the program's early days, it was spotty, with a supervisor and trappers responding sporadically as word was received that ranchers, primarily in the sandhills and western part of the state, were losing sheep or calves to coyotes.

Formula To Build A Better "Rat Trap" Rodenticide, George W.J. Laidlaw

Great Plains Wildlife Damage Control Workshop Proceedings

In the time that the Pesticides Division of Agriculture Canada has been evaluating rodenticides, it has become apparent that the formulated product's efficacy is dependent on the character of the inert ingredients as well as on the actual active toxicant. The type of food, its level of manufacture, the adhesive-binder, the attractants and preservatives can each affect the efficiency of the active ingredient. Currently, very serious problems have arisen because of the anticoagulant resistance and bait shyness that rodents have developed towards existing products.

The Unrealistic Ipm Parameters Of Vertebrate Pest Control, Rex E. Marsh

Great Plains Wildlife Damage Control Workshop Proceedings

In actual practice certain phases of integrated pest management (IPM), i.e., the utilization of a multitude of control methods, have always played a role in vertebrate pest management. For example, sanitation and rodent-proofing have always been viewed as most important aspects of rat control. IPM is a necessity in vertebrate pest control because total dependence on lethal chemical-control methods is not possible with many animal pest problems. Toxic chemicals, when used alone, are often not sufficiently effective as a single management practice.
