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 …

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.

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.

Algal Dynamics In A Cypress Stand In The Seasonally Flooded Great Dismal Swamp, Joseph A. Atchue Iii
Algal Dynamics In A Cypress Stand In The Seasonally Flooded Great Dismal Swamp, Joseph A. Atchue Iii
Biological Sciences Theses & Dissertations
The dynamics of epiphytic algae and phytoplankton were studied at a cypress stand in the Great Dismal Swamp, Virginia. Mean epiphytic algal biomass was 19.9 g m-2 and mean planktonic biomass was 3.4 g m-2.Nutrient concentrations in the epiphytic algae and the litter were determined. The algae had mean concentrations of 1.67% and 0.18%. They were found to immobilize as much as 0.5 g N m-2 and 0.06 g P m-2. This suggests that the algae are important as nutrient conservers. The phytoplankton were composed primarily of Bacillariophyceae. They exhibited a more or less …

Rocks cropping out along the North Platte River valley at Lake McConaughy provide a glimpse into Nebraska's geologic past. Here are excellent exposures of the Ogallala Group, which consists of continental sedimentary rocks deposited during the Miocene epoch of the Tertiary period of geologic time. This group of rocks extends throughout much of Nebraska (see geologic bedrock map on outside back cover) but is overlain in most places by younger stream and wind deposits of Pliocene(?) and Pleistocene age. Easily accessible, the Ogallala outcrops contain locally abundant fossils of seeds, casts of pedotubules, and occasional fossils of vertebrate animals such …

Arkansas Water Resources Center Technical Reports
Trophic-state related problems associated with waters in the United States have generated tremendous public interest and concern, particularly during the past decade. These interests and concerns led to Public Law 92-500, the mandate by Congress known as the Federal Water Pollution Control Act. Various sections of PL 92-500 directly address the need for trophic-state analyses, particularly Section 314 referred to as the Clean Lakes Program which assigns states the responsibility for classifying their lakes according to water quality, identifying methods of pollution control and restoring those lakes which have become degraded.

A Faunal Analysis Of The Springs Of The Ouachita Mountains, Arkansas, Henry W. Robison
Arkansas Water Resources Center Technical Reports
Spring ecosystems in Arkansas have historically received little attention. A faunal survey was made of 33 springs located in the core area Ouachita Mountains physiographic province. The study area was 135 x 80 km extending west from Hot Springs, Arkansas to the Oklahoma line. Springs in the Ouachita Mountain physiographic province were characterized as generally faunistically poor with often a single species such as the isopod, Lirceus h. hoppinae, being the dominant faunal element both numerically and with regard to biomass. A total of 40 species of invertebrate species and eight vertebrate species were collected from the spring environs during …

The report reassesses the condition of formerly valuable grazing lands of the Fitzroy River valley frontage lands. It is hoped that the submission will promote discussion on the problems of degenerated pastoral land and increase the resolve of all concerned to take the necessary action for their restoration. The frontage lands flank the major rivers of the area, the Fitzroy, the Margaret and the Meda and their tributaries. The frontage is capable of supporting the best pastures in the Kimberley, but unwise and uncontrolled stocking has profoundly degraded and eroded the most productive parts. There are about 5,800 square kilometres …
