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 Dec 1975

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.


The Coyote As A Game Animal, Edward L. Kozicky Dec 1975

The Coyote As A Game Animal, Edward L. Kozicky

Great Plains Wildlife Damage Control Workshop Proceedings

Coyote hunting is a very special challenge. Even though coyotes may be abundant in an area, that doesn't mean that they're easy to bag with a rifle. However, I happen to enjoy coyote calling to the point where the shooting is almost anti-climax. Others like to hunt coyotes with either sight or trail hounds, to pursue coyotes with all-terrain vehicles, and to spot coyotes while driving through the country.


Bird Control, Glen Orr Dec 1975

Bird Control, Glen Orr

Great Plains Wildlife Damage Control Workshop Proceedings

We started our program in 1967 primarily because of an economic problem in the downtown area of Wichita. We had about eight square blocks of businesses which were not getting any business because people didn't dare go downtown in the evening unless they wore their rain hats and rain gear, and I mean this literally.


Prairie Dog Control, A. Orville Sandall Dec 1975

Prairie Dog Control, A. Orville Sandall

Great Plains Wildlife Damage Control Workshop Proceedings

Before poisons were taken from the market, I had about fifteen years experience working for the Fish and Wildlife Service doing prairie dog control work. Most of this work was done for private landowners and supervising work crews for the Forest Service and B&A.


Waterfowl Damage Control, Marvin D. Schwilling Dec 1975

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.


Ground Squirrels And How To Control Them, Irving J. Mork Dec 1975

Ground Squirrels And How To Control Them, Irving J. Mork

Great Plains Wildlife Damage Control Workshop Proceedings

The Richardson ground squirrel, otherwise known as the flickertail or gray gopher, is common over most of North Dakota north and east of the Missouri River, although they were never common in the immediate Red River Valley.


Fish Population Manipulation, Robert E. Schoonover Dec 1975

Fish Population Manipulation, Robert E. Schoonover

Great Plains Wildlife Damage Control Workshop Proceedings

Fish population manipulation or control, as the term implies, may be defined as an operation or activity which results in the total removal of fish from a water area, the partial elimination of a fish population, or the selective removal of a species from a water area.


Snake Control, Steve Thompson Dec 1975

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.

An Overview Of Problem Bird Management - Rural And Urban, Joseph L. Guarino Dec 1975

An Overview Of Problem Bird Management - Rural And Urban, Joseph L. Guarino

Great Plains Wildlife Damage Control Workshop Proceedings

The economic impact of birds on agricultural crops in the U.S. is quite substantial -- perhaps as much as $100 million dollars. Methods for reducing this damage can be categorized as biological, mechanical, and chemical. The chemical approach appears to have the most potential. An avian repellent, methiocarb, has proven to be effective for reducing damage by a variety of species of birds to many sprouting and ripening crops and fruit. An avian chemical frightening agent, 4-aminopyridine (Avitrol), if federall registered for use for protecting ripening field corn and sweet corn and was shown to be effective for reducing damage …


Bird Control, George C. Halazon Dec 1975

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 Dec 1975

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 Dec 1975

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 Dec 1975

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 Dec 1975

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 Dec 1975

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 Dec 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 Dec 1975

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.


Training Needs For Future Extension Wildlife Programs, R.J. Robel Dec 1975

Training Needs For Future Extension Wildlife Programs, R.J. Robel

Great Plains Wildlife Damage Control Workshop Proceedings

I want to discuss the need for additional educational opportunities for people who will be trying to reduce wildlife damage in the future.

Woodchucks And Their Control, Robert H. Smith Dec 1975

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 Dec 1975

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.


A Precipitation Model And Experimental Correlation With Various Properties Of Pentaerythritol Tetranitrate, Thomas Rivera Dec 1975

A Precipitation Model And Experimental Correlation With Various Properties Of Pentaerythritol Tetranitrate, Thomas Rivera

Chemistry and Chemical Biology ETDs

A continuous precipitation method for the preparation of crystalline pentaerythritol tetranitrate (PETN) has been developed. The process involves the precipitation of PETN from an acetone solution by the addition of water in a static mixer. The principal independent variable is the ratio, R, of the acetone-PETN solution flow rate to the flow rate of water.

A mathematical model based on dispersed plug-flow equations adequately represents the physical process. The relationships developed can be used to predict particle size distributions, two explosion properties of PETN, and estimate the effective kinetics involved in the precipitation process. The mass-weighted mean particle size, L, …


Welcome, Robert A. Bohannon Dec 1975

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 Dec 1975

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 Dec 1975

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 Dec 1975

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.
