History Of The State Vermin Barrier Fences, Formerly Known As Rabbit Proof Fences, J S. Crawford

Research Reports

There is evidence of rabbits arriving in Australia as far back as 1788, and it is well known that others were liberated on islands around the coast, including some off the coast of Western Australia. However, they remained localised and it is now generally accepted that the rabbits which did spread originated from a small shipment of the wild type brought on the Clipper “Lightning” in 1859. They were released on “Barwon Park”, the property of Thomas Austin, near Geelong in Victoria, and within three years, had reached pest proportions

Analysis Of Small Water Management Structures In Irrigation Distribution Systems, Gaylord V. Skogerboe, Wynn R. Walker, Brent B. Hacking, Lloyd H. Austin

Reports

The Irrigation and Drainage Research Conference conducted at Utah State University (ASCE, 1964) delineated many of the research needs regarding “Small Low- Cost Hydraulic Structures for Conveyance and Distribution Systems,” which was one of the six topics considered at the conference. In discussing possibilities for accomplishing the recommended research, it was suggested by some panel members that a considerable portion of the work could be undertaken by graduate students, particularly at the Master of Science level. The intent of this report has been to sort through the large volume of literature in an attempt to define the specific research needs …

Formulation Of A Mathematical Model For The Allocation Of Colorado River Waters In Utah, Rick L. Gold, James H. Milligan, Calvin G. Clyde

Reports

A Mathematical model for the allocation of Utah’s water resources is formulated in the linear programming format. The availability of water from various sources is considered with the demands for water in each of the nine hydrologic study areas of Utah. The applications of mathematical models of this type are studied and the merits of the linear programming approach are discussed.

Simulation Of The Hydrologic-Economic Flow System In An Agricultural Area, Murland R. Packer, J. Paul Riley, Harold H. Hiskey, Eugene K. Israelsen

Reports

Like the allocation of water resources among water users, the distribution of allocated water to the subusers requires an estimate of the economic costs and benefits from a number of distribution alternatives. The most satisfactory solution maximizes the benefit cost ratio. This study is based on the premise that equitable water distribution to agricultural subusers can be more easily accomplished through the use of a technique to predict the marginal value of agricultural water. A hydro-economic model is formulated to distribute the water supply to the crops and to determine the unit value of water for the given supply. By …

Controlled Water Releases To Improve Sauger Spawning Below Fort Randall Dam, Charles H. Wahlburg

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Studies by the North Central Reservoir Investigations show that good reproduction by Lewis and Clark Lake sauger is dependent on minimum water level change on spawning grounds. Sauger spawn 7 miles below Fort Randall Dam over a 4-mi1e long gravel, rubble, boulder shoreline. Spawning begins when water temperatures at the dam reach 42 F. This usually occurs during the latter part of April or early May. Sauger spawn along the shoreline in 1 to 2 ft of water from about 8:00 PM to 12:00 Midnight. Fertilized eggs sink to the bottom and adhere to gravel ~ rubble, and boulders. Most …

Species And Abundance Of Diurnal Raptors In The Panhandle Of Nebraska, John E. Mathisen, Ann Mathisen

Nebraska Game and Parks Commission: Staff Research Publications

RECENT evidence of population declines for several species of raptors has been a subject of some concern both nationally and internationally. Although raptors are the most conspicuous birds in our environment, by virtue of their large size, flight habits, and food habits, little information is available to evaluate population densities and trends over large areas. Data are needed to provide yardsticks for judging population changes over time periods and among geographic areas.

This study was undertaken to provide information on the species and seasonal abundance of raptors in the panhandle of Nebraska for three years (1957 through 1959). Ten years …

Effects Of Main Stem Impoundments And Channelization Upon The Limnology Of The Missouri River, Nebraska, Larry A. Morris, Ralph N. Langemeier, Thomas R. Russell, Arthur Witt Jr.

Nebraska Game and Parks Commission: Staff Research Publications

Rigid control has been imposed upon the Missouri River by impounding over one-half of the upper 1,500 miles and by channeling most of the remaining river within permanent, narrow banks. These controls have caused environmental changes in the lower Missouri River, as shown by this study, of adjacent unchannelized and channelized sections of river below the main stem impoundments. Impoundments have regulated flow by evening maximum and minimum discharges and improved downstream water quality by decreasing turbidity and indirectly raising the dissolved oxygen. In addition the impoundments have contributed a limnetic cladoceran, Leptodora kindti, to the drift and have …

Bulletin No 3609 - Land Development In The South Eastern Wheatbelt, G T. Halpin, P. Nelson

Bulletins - 3000 - 3999

Interest in the development of light lands in the south-eastern wheatbelt was spurred by the many ex-servicemen seeking farms after the 1939-45 World War.

Previous attempts to develop this area had been frustrated by poor crop yields, and by the poor carrying capacity of those volunteer pastures which developed on cleared land.

Research into reasons for the poor crop results was begun in 1948-49 with trials sown by Messrs Smith and Halpin between Borden and Lake Grace. The results clearly showed the important role played by copper and zinc in successful crop growth. Since then, field trials have been conducted …

Biological Studies Of Selected Reaches And Tributaries Of The Colorado River, Nelson Thomas, Federal Water Pollution Control Administration

Publications (WR)

This report fulfills the request of the Colorado River Basin Project, Denver, Colorado, to determine the effects of municipal and industrial wastes on the aquatic life in selected waters of the Colorado River Basin. These studies were conducted with the assistance of personnel from the Colorado River Basin Project.

Federal Labeling Standards For Economic Poisons, Paul M. Ochs

Activities Of The Faa Inter-Agency Bird Hazard Committee, John L. Seubert

Bird Control Seminars Proceedings

The Federal Aviation Administration established an Inter-Agency Bird Hazard Committee in September 1966 in recognition of the increased hazard of birds to aviation. This inter-agency group was formed to obtain and consolidate informa-tion about the bird-aircraft problem and to develop ways of lessening collisions between birds and aircraft. The committee includes representatives from the Fed-eral Aviation Administration, Civil Aeronautics Board, Department of Health, Edu-cation & Welfare, National Aeronautics & Space Administration, U.S. Department of the Interior, U.S. Air Force, U.S. Army, and the U.S. Navy. The activities of the committee have been limited primarily to an advisory role. It is …

Status Of Starlicide, Philip J. Spear

Bird Control Seminars Proceedings

Starlicide is described as a slow-acting avicide for the control of starlings and blackbirds around livestock and poultry operations. The active ingredient is 3 -chloro-p-toluidine hydrochloride which has been identified by the Denver Re-search Center of the U.S. Fish and Wildlife Service as DRC-1339. A casual review of information about this bird control material suggests the following paradoxes: The use of the chemical in bird control appears to be covered by a patent, but the licensor wishes to remain anonymous. The licensee, which produces and sells the commercial material, seems unwilling to discuss the product. Let me hasten to point …

Significance And Control Of Fungal Diseases Related To Bird Roosts, Robert J. Weeks

Bird Control Seminars Proceedings

Certain fungi have been found frequently as saprophytes in areas containing large amounts of bird excreta. These fungi have the ability to survive, multiply, and cause disease once they have entered a host. Two of these are Crypto-coccus neoformans and Histoplasma capsulatum. Both may easily become airborne and be disseminated throughout an area by the prevailing winds. C. neo-formans is commonly isolated from the excreta of pigeon habitats, and in turn has been associated with clinical cases of cryptococcosis, while blackbird roosts, harboring H. capsulatum, have been responsible for several outbreaks of histoplasmosis. When either of these fungi have become …

Basic Statement On Migratory Bird Treaty, E. M. Bosak

Bird Control Seminars Proceedings

My portion of the program is the basic statement on the Migratory Bird Treaty Act regulations. Basically, laws are designed to control the actions of human beings. J. Edgar Hoover recently stated, "Man cannot live in our complex society today without a system of laws. The social system is doomed unless the laws are enforced, and the enforcement officer is ineffective unless his efforts to maintain the peace and protect life and property are supported by the government and the people." Therefore, it behooves each one of us to be aware of those laws that affect us in our everyday …

Bird Control Under A State Fish And Game Permit System, James Shepard

Bird Control Seminars Proceedings

I guess the impetus for laws in our state, really was the action of the city of Boston in 1963, when the Parks and Recreation Department felt that it was time to do something about massive populations of pigeons on the Boston Commons and in the city. The Parks Department came to our agency to find out what could be done. We immediately found as a result of a reorganization and recodification of the laws some 20 years before, that it was illegal to use or apply poisons for the purpose of killing any birds or mammals in the Commonwealth …

Cooperation Between Pest Control Operators And Regulatory Authorities, Robert M. Russell

Bird Control Seminars Proceedings

When Dr. Jackson called me to speak on the rights of the individual I told him he probably had the wrong person because I am an individual and I believe my company is an organization very prone to say "what is, is and you've got to go on with it." If I'd have heard some of the talks here today before he called me, I wouldn't be here at all, because I'm not sure what individual rights there are left! So let me change this thing around a little bit and state that instead of speaking of the rights of …

Use Of Strychnine Treated Grain For Industrial Pigeon Control, Joseph Watkins

Bird Control Seminars Proceedings

The pest bird involved in nearly 100% of our jobs has been the pigeon. We don't do killing in residential areas, nor have we done killing in downtown areas. All of our work has been confined to industrial plants and commercial buildings where strychnine, and we have used other methods that can kill the birds. In these plants we have had some problems with industrial or labor re-lations. These have been coped with by working with the union, with the labor relation people, and as high up as purchasing level. First of all we think that with strychnine if we …

Wetting Agents And Their Role In Blackbird Damage Control, Don Harke

Bird Control Seminars Proceedings

I'm going to speak on wetting agents, which are a class of surface-active agents or surfactants along with soaps or detergents. I would like to second John's philosophy on this balanced approach. Our blackbird problem in Ohio and Michigan is sufficiently serious that we can scarcely afford to overlook any measure of control. Wetting agents are not a new happening on the blackbird damage control scene. Actually since the early '60's we have been interested in finding the ideal agent and method of application for lethal control of blackbirds, starlings, and their roosts. The principle, as with so many other …

Drc-1339 In Feedlots, John W. Degrazio

Bird Control Seminars Proceedings

Since 1960, the Denver Wildlife Research Center has been investigating methods of controlling starlings (Sturnus vulgaris) at livestock feedlots. One chemical developed at the Denver Center is a slow-acting avicide, DRC-1339 (3-chloro-p-toluidine); it is well accepted and highly toxic to starlings, generally less toxic to other birds, and relatively nontoxic to mammals. It possesses no secondary hazard to avian and mammalian predators. A Cooper's hawk (Accipiter cooperii), a marsh hawk (Circus cyaneus), and a sparrow hawk (Falco sparverius) subsisted on field-killed DRC-1339 starlings for 3- and 4-month periods with no ill effects. In our tests, poultry pellets (Purina Layena Checkers') …

Solutions To Problems: Concluding Comments, John R. Beck

Bird Control Seminars Proceedings

This concludes the session which is marked for the morning. These gentlemen have presented you with a number of alternative methods or op-tions. There are a couple of concluding remarks I'd like to make. One, to those of you who have attended or specialized in bird control conferences or meetings, I'm quite certain that you realize that in terms of something new and startling, there have been no major advances in the past four years in terms of techniques or materials. However, the presentation which we have just concluded very clearly brings out the fact that there have been many …

Costs Of New Materials: The Manufacturer's Dilemma, Dan Macdougall

Bird Control Seminars Proceedings

I thought it was possible that some of you might not be acquainted with some of the frustrations which are involved in jousting with the bureaucracy in Washington. So I thought I would review that situation very briefly for you, particularly in regard to the compound Queletox. We will confess that we had some real qualms about accepting this material for control as a bird toxicant initially. And the reasons we were concerned about this were because the compound was being used in other areas as an agricultural chemical. It was registered for mosquito control, and it was being used …

New Materials For Bird Control, John W. Degrazio, Philip J. Spear

Bird Control Seminars Proceedings

A variety of methods is necessary to solve the many bird damage problems that occur in agriculture and other fields of interest. It is apparent that no one method can be used to provide answers for all damage situations; each problem and problem area is unique and requires thorough knowledge and investigation before intelligent measures of bird control can be applied. Thus, basic research in the laboratory and initial field studies are necessary to arrive at the most safe, efficient, and economical method of bird damage control possible for each situa-tion. The use of chemicals for damage control is one …

Concluding Remarks: Fourth Bird Control Seminar, William B. Jackson

Bird Control Seminars Proceedings

I had three basic ideas. One: that we were talking about bird management, not bird control. This is a recurrent theme through all four of our conferences I think. We're saying secondly that spot control, taking care of this problem at this place with this specific technique, is important and we need more tools; but we need to look at the larger aspect of the environment, the population, and its relationship—an ecological approach. Thirdly, communication, whether it be with the general public or specific interest groups or among this group of professionals involved in bird management, is important; and we …

Bait And Bait Materials, Fred R. Courtsal

Bird Control Seminars Proceedings

I'm going to speak about bird baits that are produced by the rodent-control fund. In my estimation, there are about six criteria for mixing good, high quality bait materials. The first one would be a toxicant. This is the first thing people talk or think about. I would assume that you would select a toxicant that has the quality to do the intended job. The second point is the sticker. So our criteria for a sticker are as follows: good adhering qualities, good spreading qualities (by this I mean if you introduce the toxicant into a sticker as is often …
