Waterfowl Damage Control, Marvin D. Schwilling

Great Plains Wildlife Damage Control Workshop Proceedings

Waterfowl damage is primarily grain crop depredation that occurs on various agricultural crops, particularly in fall and winter. Field feeding begins as birds flock up on staging areas in preparation for their move along migration routes to the wintering areas.

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.

Committee Proposals For Development Of A Great Plains Wildlife Damage Control Handbook

Great Plains Wildlife Damage Control Workshop Proceedings

In 1969, Bob Henderson developed a two-volume Wildlife Damage Control Handbook for use by county extension agents throughout Kansas. The handbook was well received and was felt to be of definite value to the overall wildlife damage control program in Kansas.

Bats, Biology, And Control, Stephen P. Kincaid

Great Plains Wildlife Damage Control Workshop Proceedings

Although bats are not commonly thought of as major members of the animal kingdom, they are one of the most numerous of land vertebrates. Bats are thought to have originated in the Old Wordl Tropics and are now almost world-wide in distribution. Bats make up the order Chiroptera, and they are closely related to the hedgehog, shrew and mole.

Snake Control, Steve Thompson

Great Plains Wildlife Damage Control Workshop Proceedings

Whether wild animals are benificial or injurious depends on the time and the place. It seems that no one likes to have venomous or even harmless snakes in his corral, in his yard, or even on his doorstep; but every spring and fall many people are confronted with this situation. Many requests are recieved each year on how to rid an area of these unwanted reptiles.

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.

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. …

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.

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.

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 …

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.

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.

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.

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. …

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.

Tertiary Treatment Of Wastewater Using Oxidation Ponds, Robert A. Lauderdale, John R. Moeller, Raymond D. Hamilton

KWRRI Research Reports

The purpose of the project was to determine the value of using lagoons as a supplemental process for treating the effluent from an activated sludge wastewater treatment plant.

Only tentative conclusions can be suggested since the project was not carried to completion. It appears that lagoons will have only minimal effect on the amounts of total nitrogen and phosphate in the plant effluent, although conversion of a portion of the ammonia to nitrate can be expected. However, the concentration of ammonia was never lower than that required by EPA guidelines. Some reduction of soluble BOD appears to occur, perhaps through …

Trace Metals And Major Elements In Water-Soluble Rocks Of Northwest Arkansas, George H. Wagner, Kenneth F. Steele, Doy L. Zachry Jr.

Arkansas Water Resources Center Technical Reports

Trace metals in limestone are potential water contaminants because they can enter the ground water when the limestone is dissolved by carbonic acid and other naturally occurring acids. Four local limestones, the St. Joe and Pitkin Formations (Mississippian) and the Brentwood and Kessler Members of the Bloyd Formation (Pennsylvanian) were sampled in a five county area in Northwest Arkansas. Atomic absorption analyses were made for Na, K, Mg, Ca, Zh, Cu, Ba, Fe, Co, Cr, Ni, Mn, Li and Sr on the acid soluble material of the samples. All the limestones are relatively pure CaCO3 with Pitkin the purest, 93.4%. …

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.

The Law Of Water Allocation In Kentucky, Richard C. Ausness, Bill H. Flynn

KWRRI Research Reports

This study discusses navigability concepts, consumptive rights to surface and ground waters, the disposal of diffused surface waters and the administration of Kentucky's statutory water allocation system.

Federal regulatory powers are based on navigability as is state ownership of submerged lands. Kentucky uses the ebb-and-flow test of navigability to determine title to submerged lands but uses a navigability-in-fact test to determine the scope of state regulatory authority. Consumptive uses of water in Kentucky are governed by the riparian landowner to use as much water as he needs as long as his use does not interfere with the legitimate uses of …

Survival And Growth Rate Of Channel Catfish As A Function Of Dissolved-Oxygen Concentration, R. W. Raible

Arkansas Water Resources Center Technical Reports

Channel catfish were raised in water-recirculating systems for several periods of about six months duration each. Initial stock was fingerling size fish (10 to 20 grams). At dissolved-oxygen levels below 2.5 parts per million, mortality was high. Fish raised in tanks held at dissolved-oxygen levels between 3.0 and 6.8 parts per million showed increased gains of weight for each increment of added oxygen. Weight gains were as much as 50 percent higher at 6.8 parts per million compared with weights at 3.0 parts per million. Feed conversion was good in all cases. When feeding was limited to demand, feed conversion …

Biochrome Analysis As A Method For Assessing Phytoplankton Dynamics Phase Ii, Richard L. Meyer

Arkansas Water Resources Center Technical Reports

Selected chemical, physical and biological parameters were determined for a man-made lake, Beaver Lake, on the White River of Arkansas and Missouri. The research program determined the qualitative and quantitative aspects of the temporal and spatial distribution of the algal subcommunities. It was determined that the epipelic, epilithic, epizooic and metaphytic subcommunities had little influence on the euplanktonic subcommunity. The relationship between the qualitative and quantitative analysis of the biochromes chlorophyll-a, -b, and -c and the phytoplankton species clustered into biochrome sets is discussed. The temporal and spatial distributional patterns of temperature, oxygen, ammonia-N, nitrate-N, orthophosphate-P and silicates are described …

Pollution Abatement From Cattle Feedlots In Northeastern Colorado And Nebraska, L. K. Porter, F. G. Viets Jr., T. M. Mccalla, L. F. Elliott, F. A. Norstadt, H. R. Duke, N. P. Swanson, L. N. Mielke, G. L. Hutchinson., A. R. Mosier, G. E. Schuman, Lynn R. Shuyler, C. E. Evans

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. …

Water As A Factor In Energy Resources Development, A. Bruce Bishop, Melvin D. Chambers, William O. Mace, David W. Mills

Reports

Water, in many cases, is a key factor in the development of energy resources in the western states. The total water supply available in the arid west is fixed; yet potential water uses in the region are growing continually. In fact, in many areas quantities of water desired to be put to beneficial use has already surpassed the limit of local supplies as indicated by filings for water rights. The availability of water, in adequate quantities and of suitable quality, is one of the essentials to the economic viability of some economic sectors in the states in the Colorado River …
