Bird Control, George C. Halazon

Great Plains Wildlife Damage Control Workshop Proceedings

We did a little work with pigeon sterilants six years ago. We didn't really have too much luck on bird control on pigeons because of the life of the pigeon. In other words we couldn't do it fast enough to satisfy the public because of the relatively large numbers of years required before the bird dies.

A Live Trap For Birds Attending A Feeding Station, J.L. Hart, L.L. Todd

Great Plains Wildlife Damage Control Workshop Proceedings

An effective live trap for capturing nuthatches, titmice, and woodpeckers was constucted from hail screen and modified mouse traps. Over 88 percent of active sets resulted in captures.

Controlling Mole Damage, F. Robert Henderson

Great Plains Wildlife Damage Control Workshop Proceedings

The kind of mole found in Kansas is the eastern mole, Scalopus aquaticus. Moles are small, mouse-sized mammals adapted to living underground. They are characterized by enlarged forefeet with long claws, stout necks and powerful shoulders which make them capable burrowers. Unlike those of mice and shrews, the noses and forefeet of moles are pink and hairless.

Progress In Coyote Hunting Depredations Research, Samuel B. Linhart

Great Plains Wildlife Damage Control Workshop Proceedings

Coyote depredations control research from the end of World War II to about 1960 was characterized by low levels of funding, a minimum of research facilities, an emphasis on lethal agents, few legislative restrictions, a lack of public interest, and little concern for the environment. Establishment of the Leopold Committee (1964) and Cain Committee (1971) were evidence of a growing public concern and awareness of the coyote-livestock problem.

Control Of White-Tailed Deer In Field And Orchard, Forrest D. Loomis, Ronald Ogden

Great Plains Wildlife Damage Control Workshop Proceedings

As deer populations increase in most areas of the mid-west, and deer habitat is constantly shrinking because of man's activities, damage done to crops, orchards, and other plantings is increasing. No new or revolutionary control or repellent has been perfected to alleviate this complex problem. Annual hunting still offers the best and cheapest method of control.

Thoughts About Wildlife Damage Control, Raymond W. Matheny

Great Plains Wildlife Damage Control Workshop Proceedings

Gentleman, it is my intention today to give you a brief history of EPA and its involvement in predator control, outline basic registration requirements for pesticides, show slides of the use of sodium cyanide capsules in the M-44 ejector mechanism in the experimental use permit programs and comment upon the restrictions set forth in Administrator Train's ORDER of September 16, 1975.

Beaver Damage Control, James E. Miller

Great Plains Wildlife Damage Control Workshop Proceedings

The beaver (Castor canadensis), our largest North American rodent, is praised by many as being a natural conservationist; however, to others he is a destructive nuisance and pest. In many chronicles, the beaver is lauded to be one of the resources that speeded up the settling of our Great Northwest Territory. Certainly, such explorers as Lewis and Clark depended greatly upon the beaver hide for revenue as well as varter.

Cultural And Physical Methods For Managing Problem Birds, Donald F. Mott

Great Plains Wildlife Damage Control Workshop Proceedings

Although chemicals now available (or that soon should be) appear to be the answer to many bird problems in agricultural crops, it is appropriate to also review some of the cultural and physical methods currently in use.

Woodchucks And Their Control, Robert H. Smith

Great Plains Wildlife Damage Control Workshop Proceedings

Woodchucks, or groundhogs, (Marmota monax) aer found in the eastern edge of the Great Plains. The first part of the scientific name, Marmota, is the Latin word for "marmot," the name given to the European marmot or the North American marmot which are close relatives of the woodchuck. The last part, monax, is an American Indian name for this rodent and means "the digger"; it alludes to the woodchuck's habit of excavating burrows.

Raccoon Damage Control, W. Alan Wentz

Great Plains Wildlife Damage Control Workshop Proceedings

Raccoons are found throughout the United States, and in most cases they are expanding their range into previously unoccupied habitats. Raccoons are often water-associated, but in the Great Plains they often occur a considerable distance from the water. In the Great Plains states, the expansion of agriculture has apparently allowed raccoons to move westward and northward. It is possible that the availability of old homesteads, buildings, haystacks, dumps, and towns has been instrumental in allowing raccoons to survive the winter.

Welcome, Robert A. Bohannon

Great Plains Wildlife Damage Control Workshop Proceedings

The Workshop which was held two years ago was a success. According to registration records this year, people from all of the Great Plains states are in attendance and 92 persons are registered. We are especially pleased to welcome C.F. Barrett, Supervisor of Animal Pest Control of the Alberta Department of Agriculture who travelled the longest distance to attend.

Tree Squirrel Damage Control, Robert L. Carlton

Great Plains Wildlife Damage Control Workshop Proceedings

Unlike some wildlife species, tree squirrels are treated as game animals in every state where found. Thus, there are often restructions on times when tree squirrels may be controlled. In areas of high human population, there may be restrictions on ways in which squirrels may be controlled. Finally, because of the human affection for squirrels, there may be places where effective control is almost impossible.

Management Of Cats - Felidae In Colorado, Major L. Boddicker

Great Plains Wildlife Damage Control Workshop Proceedings

Panthers, catamounts, pumas, mountain lions have occurred in legend and folklore from the first years of explorers in the new world until today. They are timid shadows of the night which emit blood curdling screams and yowls. They have occasionally (rarely) killed children and adults (Nevada 1974). Have a taste for horseflesh. They feed heavily on deer and have the capability of killing adult elk.

Rabbit Damage Control, Edward K. Boggess

Great Plains Wildlife Damage Control Workshop Proceedings

In discussing the control of damage caused by rabbits in the Great Plains area it is helpful to distinguish between the true rabbits, of the genus Sylvilagus, and the so-called jackrabbits, of the genus Lepus, which are really hares. Laws governing the control of rabbit damage vary between states. In Kansas, no poisons can be used for controlling rabbits. This leaves basically three approaches to solving a rabbit damage problem. These are: removal, exclusion and the use of repellents.

Feral Mammal Damage And Control, Philip S. Gipson

Great Plains Wildlife Damage Control Workshop Proceedings

Feral populations of five domestic mammals, dogs (Canis familiaris), house cats (Felis catus), hogs (Sus scrofa), burros (Equus asinus) and horses (Equis caballus), presently occur in North America. At times these animals cause problems, damaging crops or livestock, or competing with livestock and native wildlife for food and living space. Free-living bands of a sixth species, cattle (Bos taurus), formerly occurred in the Southwest. Feral mammals are adaptable, and they have become a permanent part of the fauna in many states. Researchers generally ignored feral mammals in the past, although numerous reports have been published in the past 10 years. …

Wildlife Damage Control Workshop Summary, Philip S. Gipson

Great Plains Wildlife Damage Control Workshop Proceedings

The second Wildlife Damage Control Workshop was a success. Damage control authorities and conservationists shared knowledge and philosophies regarding control objectives, technology and laws. This workshop differed from the first Damage Control Workshop (Henderson 1973) by treating a variety of wildlife damage including problems with nuisance birds and commensal rodents to feral animals, coyotes, and cougars. The first workshop focused on damage caused by coyotes.

4-H And Youth Related Programs, Major L. Boddicker

Great Plains Wildlife Damage Control Workshop Proceedings

The value of a youth oriented wildlife management program is obvious. Youth is an audience with an open mind, often not committed to old errors. With a proper and intensive education program, a strong future impact can be made on the acceptance and success of animal damage control programs. Programs of quality can change a youth's outlook on problem wildlife from one of apathy or intolerance to one of positive management and high damage tolerance.

Control Of Wild Animals And Public Opinion, Charles H. Callison

Great Plains Wildlife Damage Control Workshop Proceedings

In 1957 the noted ornithologist Robert Cushman Murphy and other landowners on Long Island went to court in an effort to enjoin the U.S. Department of Agriculture from the aerial spraying of DDT to "eradicate" the gypsy moth. This event was years before Rachel Carson wrote Silent Spring. It may have been the first of the modern environmental law suits, although no one called it that. Certainly it was a forerunner of the modern environmental law organizations, because about ten years later the Environmental Defense Fund, was born, interestingly, in Dr. Murphy's neighborhood on Long Island. EDF's first great task …

Commensal Rodent Damage Control, Robert L. Carlton

Great Plains Wildlife Damage Control Workshop Proceedings

Commensal rats and mice are among the only animals about which no good can be said. Each year rats and mice are estimated to cost the American public over $1 billion. This loss is due to contamination of food stuff, structural damage, etc. To give an idea how these rodents can effect the economic picture, assume a rat will eat 25 pounds of chicken feed per year and foul another 25 pounds to such extent it cannot be used as feed (some estimates are as much as ten times greater). The house mouse will consume about 5 pounds per year. …

How To Handle Problem Skunks, F. Robert Henderson

Great Plains Wildlife Damage Control Workshop Proceedings

There are two species of skunks in Kansas. The striped skunk is about the size of a large house cat, generally black in color with two white stripes running from the base of the skull to the large bushy tail. Solid black indivduals are known to occur, but only rarely. The spotted skunk is a smaller mammal about the size of a half-grown house cat. The spotted skunk is a more active, agile animal and a good tree climber.

Muskrat Damage Control, James E. Miller

Great Plains Wildlife Damage Control Workshop Proceedings

Muskrat control, like any type of vertebrate pest control, is not an easy task. It requires not only practical effective methods, but a diligent effort, as well. When speaking of muskrat control, we are not implying total eradiction, because, first of all, it would not be possible, and secondly, in most areas other than agricultural croplands, they are not considered a pest.

Physical And Chemical Properties Of Outdoor Beef Cattle Feedlot Runoff, C. B. Gilbertson, J. R. Ellis, J. A. Nienaber, T. M. Mccalla, T. J. Klopfenstein

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Within the past decade, emphasis has been placed on the quality of our environment. Beef cattle feedlots have been singled out as a significant source of environmental pollution. Environmental protection provided by control facilities requires basic knowledge of the physical and chemical properties of feedlot runoff. This bulletin summarizes studies of physical and chemical properties of beef cattle feedlot runoff completed from August, 1968 through December, 1972.

United States Environmental Protection Agency: Publications

Climatic factors, feedlot runoff, and organic material in the runoff were evaluated in experimental and commercial feedlots. The effects of slope, stocking rates, terraces, basins, and holding ponds were evaluated to obtain the best controls for containing runoff. In eastern Nebraska, 70 cm annual precipitation produces 23 cm of runoff; whereas, in northeastern Colorado, 37 cm annual precipitation gives only 5.5 cm of runoff. Large applications of runoff liquid, up to 91 cmon grass-Ladino and 76 cm on corn, in Nebraska did not decrease yields; however, in northeastern Colorado, the concentrated high-salt runoff required dilution before direct application to crops. …

Evaluation Of Recovery In A Polluted Creek After Installation Of New Sewage Treatment Procedures, Robert A. Kuehne

KWRRI Research Reports

Response of Hickman Creek near Lexington, Kentucky to alleviation from serious sewage pollution was studied from January, 1973 through July, 1974. Wastes are now handled from an efficient secondary treatment facility and four sequential polishing lagoons before chlorination and discharge to West Hickman branch.

Physico-chemical tests gave no strong indication of residual pollution effects at the start of the study, approximately six months after the treatment facility opened. At low flow a slight oxygen sag, probably associated with algal growth in the lagoons, persists downstream from the outfall. Mean values for turbidity, nitrates and COD are somewhat higher at the …
