Efficacy And Costs Of Four Rodenticides For Controlling Columbian Ground Squirrels In Western Montana, Steven W. Albert, C. Raymond Record
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
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
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
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 …
Status Of The Environmental Protection Agency's Review Of Rodenticides, William C. Dickinson
Status Of The Environmental Protection Agency's Review Of Rodenticides, William C. Dickinson
Great Plains Wildlife Damage Control Workshop Proceedings
The EPA is currently conducting RPAR reviews on two widely used rodenticides, strychnine and Compound 1080. In addition, Registration Standards have been developed for the rodenticides warfarin and Fumarin®. The Zinc Phosphide Standard is currently under development. The author briefly explains the factors the Agency has been taking into account in reaching final resolution on these chemicals as well as outlining EPA's re-registration and RPAR programs.
Prairie Dog Dispersal In Wind Cave National Park: Possibilities For Control, Monte G. Garrett, William L. Franklin
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
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. …

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.
Ipm - An Overview, R.E. Gold
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
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
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
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 …
Nebraska's Animal Damage Control Program, Robert P. Kelly
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.

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.

Opening Comments And Extension's Role In Nebraska, Leo E. Lucas
Great Plains Wildlife Damage Control Workshop Proceedings
I would like to echo Dr. Massengale's comments in welcoming you to Nebraska. We are pleased to have you here. Nebraska is a major agricultural state. Ninety-seven percent of the land is privately owned and most of it is in agricultural production of one type or another. Nebraska ranks fifth in total receipt sales of Ag products. Nebraska ranks second in the nation in numbers of cattle on feed, fourth in cash receipts from all livestock marketing, first in production of great northern beans, popcorn and alfalfa meal, and fourth in corn production. Agriculture is important to the state's economy.
Future Of Pesticides In Vertebrate Pest Control, Rex E. Marsh
Future Of Pesticides In Vertebrate Pest Control, Rex E. Marsh
Great Plains Wildlife Damage Control Workshop Proceedings
The present state-of-the-art provides little information which would lead to the conclusions that animal damage control will take a new direction away from chemicals. Hence, vertebrate pesticides whether toxicants or repellents will remain essential components of integrated pest management programs. The future of vertebrate pesticides is far from being bright, but current developments offer some good reasons to remain optimistic. The various factors which influence the development of new vertebrate pesticides (principally rodenticides) are discussed along with projections of stable as well as changing trends. Speculation on the future of vertebrate pesticides may provide tentative directions for some and forecast …
The Unrealistic Ipm Parameters Of Vertebrate Pest Control, Rex E. Marsh
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.
A Common Sense Approach To Commensal Rodent Control, Edward F. Marshall
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 …

L:Egal Problems Of Bird Damage Control - Protected Species And Practical Solutions, Ronald D. Ogden
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
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 Review Of Prairie Dog Diet And Its Variability Among Animals And Colonies, Kathleen A. Fagerstone
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 …
Outwitting The House Sparrow [Passer Domesticus (Linnaeus)], William D. Fitzwater
Outwitting The House Sparrow [Passer Domesticus (Linnaeus)], William D. Fitzwater
Great Plains Wildlife Damage Control Workshop Proceedings
With the decline of house sparrow populations during the first quarter of this century, control research attention shifted to other avian species so little new is available on either life history studies or management. Solutions to animal damage control problems are generally through (1) environmental controls, (2) protection of crops and/or sites, and (3) population reduction. In the case of sparrow problems, environmental controls are of limited application as the birds prefer the habitat modifications made by man. Protection of crops or sites relies on repellents which are generally ineffective against this particular species. The only viable population level controls …
