Meeting The Meadow Mouse Menace, William D. Fitzwater

Vertebrate Pest Conference Proceedings: 1st (1962)

The orchardist has many ways to lose money but one of the best is to ignore his mouse problem. This apparently insignificant, short-tailed little rodent by his unobtrusive but systematic attacks on the growing tissue of trees can be very expensive. The Indiana Extension Horticulturist has stated that mice are the number one cause for orchardists going out of business in recent years in that State. Moreover, the problem is not a recent one as a questionnaire to county agricultural agents in 1924 (Davis, 1925) showed that field mice were even then considered a problem in 40 per cent of …

Ground Squirrel Control In California, Richard H. Dana

Vertebrate Pest Conference Proceedings: 1st (1962)

The control of ground squirrels in California is important in two ways. First, it is necessary to prevent destruction of agricultural crops. Second, it is important from a health standpoint where rodent-borne diseases have been demonstrated to be present. Ground squirrel control in this State is the responsibility of the county agricultural commissioners, the State Department of Agriculture and on Federal lands the Bureau of Sport Fisheries and Wildlife. Most control measures are concerned with but two of the nine species of ground squirrels found in California. These include four subspecies: Beechey ground squirrel (Citellus beecheyi beecheyi), Douglas ground squirrel …

Controlling Muskrats, Rollo E. Talbert

Vertebrate Pest Conference Proceedings: 1st (1962)

Today damage attributed to muskrat activities occurs both to irrigation systems and waterways serving agricultural interests as well as to power company installations, waterfowl refuges and hunting clubs. Direct damage or destruction of agricultural crops is relatively minor although the muskrat is known to feed on a variety of produce including ear corn, alfalfa, clover and carrots and frequently will cut a rather wide swath of rice near water control boxes separating rice paddies. The brief activities of fur trappers appear to have little significance as applied to alleviating these losses, so we are forced to recognize that we will …

Linnets, Horned Larks, Crowned Sparrows And Woodpeckers, James W. Koehler

Vertebrate Pest Conference Proceedings: 1st (1962)

CALIFORNIA HOUSE FINCH Carpodacus mexicanus frontalis: Depredations. In California the linnet is an abundant resident throughout the State wherever food and water are available. It is most numerous on the valley floors and in the foothills where man's development has created an extensive favorable habitat. The linnet is primarily a seed eater and before the introduction of domestic fruits into California probably lived largely on weed seeds. Linnets attack the ripening fruit of the apricot, cherry, peach, pear, nectarine, plum, prune, avocado, grape, apple, fig, strawberry, blackberry, raspberry and many others. They disbud almond, apricot, pear, peach, plum, prune and …

Controlling Yellow-Billed Magpies (Pica Nuttalli), Rex Lynda Ii

Vertebrate Pest Conference Proceedings: 1st (1962)

The yellow-billed magpie is a little smaller than the American or black-billed magpie, but the difference in size is very slight. The birds look exactly alike, except one has a black beak and the other has a yellow bill and a bit of yellow skin back of the eye.There are concentrated populations in the Los Banos area, Gustine area, and along the course of the Merced River comprising about 19,100 acres. They are occasionally seen in other areas of the County, but only infrequently observed in the southwestern portion of the County. The heaviest populations are in walnut orchards, dairy …

Mole And Woodrat Control, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 1st (1962)

MOLES: In regions where moles thrive, lawns in golf courses, parks, cemeteries and home yards are often made unsightly by dirt mounds and ridges pushed up by the active little animals. In cultivated land, moles may cause consider¬able economic loss through their burrowings. Mole control can be divided into six basic categories: exclusion, repellents, gases, toxic baits, reduction of food supply, and trapping. Un¬changed over the years, trapping is still considered the most reliable of all methods of control, however, under certain conditions or situations, the other methods of control may be extremely useful. WOOD RATS: The native wood rat …

Banquet Address: People, Pests And Some Plans, Daniel G. Aldrich Jr.

Vertebrate Pest Conference Proceedings: 1st (1962)

We can probably say that the California way of farming has made California fanners the most over-run hosts to vertebrate pests in the agricultural world. We can certainly say, too, that new pests—and here I don't mean people--are on their way. I'm told that the starlings are just exploring here now. The relatives are coming later. We'll see, and hear, a lot more of them. Our problem is: How do we keep from being such good hosts to our small vertebrate guests? I have been told by experts that right now the vertebrate pest control man is woefully underequipped for …

Control Of Pocket Gophers, Maynard W. Cummings

Vertebrate Pest Conference Proceedings: 1st (1962)

Pocket gophers occur only in North and Central America but within this vast area few other native rodent groups are more widely distributed (Anthony, 1928). None are more adaptable, either to natural extremes of habitat or to changed conditions brought about by agricultural development and other man-made environmental modifications. They occupy coastal areas, inland plains and valleys, desert and alpine meadow, from sea level to above timber line in a multitude of vegetation and soil types. This practically universal distribution has, of course, led to the recognition by naturalists of many species and subspecies. California alone contains at least 75 …

Methods Of Controlling Starlings And Blackbirds, Adolph Zajanc

Vertebrate Pest Conference Proceedings: 1st (1962)

Most people have accepted the fact that all living things can be beneficial to mankind in some way or other. This is especially true of our wild birds, since they provide enjoyment and wholesome recreation for most of us, regardless of whether we live on farms or in the city. But despite the fact that wild birds are for the most part beneficial, at times individuals or populations of certain species can seriously affect man's interests. When such situations occur, some measures of relief are desirable and usually eagerly sought. This report is not intended to answer all the questions …

Control Of Meadow Mice, Kangaroo Rats, Prairie Dogs,, John A. Ludeman

Vertebrate Pest Conference Proceedings: 1st (1962)

Meadow mice, kangaroo rats, prairie dogs and cotton rats are broadly classified as field rodents. The control of their populations have been necessary since man first began to farm and raise livestock within the areas in which these rodents live. The intensity of control has varied with land values and the population fluctuation of the rodents. Rodent control, like other farming practices must be profitable to the land owner, or he cannot afford to undertake a control program. If he is to continue in business his control efforts must be done efficiently and as successfully as possible. To accomplish these …

Control Methods For Snakes, Elbert M. Brock, Walter E. Howard

Vertebrate Pest Conference Proceedings: 1st (1962)

Of the various types of wildlife that home owners find undesirable, snakes are probably the leading offenders. Because of much false teaching, many persons have a great dread of even non-venomous snakes; hence control often is practiced when not needed. Nevertheless, very few people are willing to accept the presence of snakes in their gardens or their yards, especially if there is a concern for children playing in the area. For this reason snake control is often desirable about homes and suburban housing areas. Other situations where controls might be justified are recreation areas, farms, bird sanctuaries, duck nesting marshes, …

EFFICIENT calling of maiden ewes before they join the breeding flock is an essential part of any policy of flock improvement.

Removal of the low wool producers should be one of the first considerations when culling the flock.

Flooding And Salt Problems In The Wheatbelt, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

VALUABLE land has become salty in parts of the West Australian agricultural areas because most of the surrounding land has been cleared and developed for agriculture.

This salting of a small proportion of the land is part of the price paid for the development of agriculture in this State.

Drainage is not the answer to the wheatbelt flooding and salt land problems.

A more practical approach is to limit runoff from sloping land, and to make good use of salt-affected land by growing salt tolerant perennial pastures on it, says the Soils Division of the Department of Agriculture.

Geology Of The Esterbrook Area, Converse And Albany Counties, Wyoming, Michael Nolan Greeley

Masters Theses

"The Esterbrook area lies within the Laramie Range in Converse and Albany Counties, Wyoming. Exposures include Precambrian metamorphic and igneous rocks, the Tertiary White River formation, and Quaternary alluvium.

Hornblende schist and mica-quartz schist comprise the Precambrian metamorphic rocks. Foliation planes of these rocks trend northeast and dip steeply to the southeast. Metamorphic rocks of younger age probably lie to the southeast.

A distinctive, Precambrian silicic pluton of biotite-leucogranite with marginal zones of muscovite-leucogranite and alaskite passively intrudes the metamorphic rocks, generally parallel to the foliation trends. Numerous granite pegmatites show a zonal distribution around the pluton and appear to …

Variation Of Sensitized Fluorescence With Penetration Depth Of Incident 2537a Radiation, George Grayson Robinson

Masters Theses

"An investigation of the sensitized fluorescence of a thallium and mercury mixture using a variable depth cell and photomultiplier type of detection is discussed. Data are given to indicate the variation of the intensity of the 3519A thallium line as a function of thallium temperature, as a function of mercury temperature, and as a function of cell depth. Explanations of results require the use of generally accepted ideas concerning energy transfer, emission, and absorption."

Cobalt : Its Use To Control Wasting Disease, Laurence C. Snook

Journal of the Department of Agriculture, Western Australia, Series 4

FOR many years it was assumed that in Western Australia cobalt deficient areas were restricted to a coastal fringe which rarely extended more than 20 miles inland.

This has proved a costly false assumption. During recent years cobalt deficiency has been diagnosed over extensive areas of inland country.

Molybdenum Deficiency On Lighter Soils, Edgar Noel Fitzpatrick
