Long Term Vole Control In Ontario Apple Orchards, Zia Siddiqi, W. D. Blaine, Stan Taylor

Eastern Pine and Meadow Vole Symposia

The results obtained so far in this 3 year study have shown that the plots with poisoned bait feeder stations suffered significantly less tree girdling than the plots treated with the fall broadcast application of 2% zinc phosphide. Similar timings were also observed in number of voles per plot, however, the vole population was much lower than the previous year. Considerable interest has been shown by apple growers in adopting this method of vole control at a commercial level.

Efficacy Of Spring Broadcast Rodenticides In The Hudson Valley, New York, Paul F. Steblein, Pamela N. Miller, Milo E. Richmond

Eastern Pine and Meadow Vole Symposia

Subsequent to the prohibition of endrin use in New York State, a variety of alternate rodenticides and methods of rodenticide application have been examined in an effort to develop effective control measures for the pine vole, Pitymys pinetorum. These studies indicate that the manner in which the rodenticides are applied substantially influences their effectiveness in controlling pine voles. Specifically, in our experience placing poisoned bait directly in the animal’s subsurface tunnel systems has proved to be the most effective means of vole control. However, this method of bait placement is both time consuming and expensive. An alternate more cost-effective method …

Velsicol Markets More Than A Rodenticide, Velsicol Chemical Corporation

Eastern Pine and Meadow Vole Symposia

Manufacturer's responsibility does not end with production of a high quality bait. There are several excellent rodenticides on the market today, but their effectiveness depends on the applicators understanding of what he is doing and why he is doing it. That's why Velsicol has shifted so much of its emphasis to studying rodent behavior and rodenticide application technology. To provide orchardists with an understanding of the dynamics of orchard vole control, Velsicol developed an educational program based on integration of good management practices with chemical and non-chemical methods of control. The program covers orchard cultural practices, identification of voles, vole …

Highlights Of The Seventh Eastern Pine And Meadow Vole Symposium, Ross E. Byers

Evaluation And Accessing Of Data For A Water Resources Simulator, Richard C. Peralta, Roberto Arce, Timothy Skergan

Arkansas Water Resources Center Technical Reports

This report evaluates the availability of data needed to use a groundwater simulation model for real time conjunctive water management in the Arkansas Grand Prairie. It is assumed that the goal of such management is to protect existing groundwater rights by maintaining water levels so that wells do not go dry, even in time of drought. Sufficient hydrogeologic data exists to use the simulation model to predict the effect of known pumping rates on groundwater levels. Developing an optimal set of "target" levels and annually managing pumping to achieve those levels requires additional data: fall groundwater levels, degree of connection …

Expansion Potential For Irrigation Within The Mississippi Delta Region, Robert N. Shulstad, Ralph D. May, Jon Mark Erstine, Blake N. Phillips, Billy E. Herrington Jr.

Arkansas Water Resources Center Technical Reports

17.6 million acres, or 73 percent, of the Mississippi Delta Region is currently cropland and possesses the physical characteristics of slope, texture and soil type which are recommended for irrigation. Economic feasibility of expanding irrigation by flood, furrow and center pivot methods were examined under 24 scenarios representing two sets of crop prices, yield levels, production costs, opportunity costs and six crop rotations. Irrigation was economically feasible for 56 to 100 percent of the cropland across all scenarios. Approximately 88 percent of the cropland can be economically irrigated with flood or furrow in its present form, 8 percent yield highest …

The Costs And Benefits Of Soil Erosion Control In The North Lake Chicot Watershed, Robert N. Shulstad, C. Tim Osborn, Alan D. Mcqueen

Arkansas Water Resources Center Technical Reports

Lake Chicot is divided by a levee into two basins, the high quality northern basin and the extremely polluted southern basin. Water quality in the northern basin of Lake Chicot is diminishing due to soil erosion. Costs for alternative control programs for the seventeen fare, 11,470 acre northern watershed were estimated. Twenty-nine combinations of rotations and best management practices were evaluated. Soil loss can be reduced almost 25 percent from 4.2 tons per acre to 3.2 tons per acre, while increasing net returns to farmers from $83.94 per acre to $107.28 per acre by altering present cropping patterns. A prohibition …

Nutrients And Acid In The Rain And Dry Fallout At Fayetteville, Arkansas (1980-1982), George H. Wagner, Kenneth F. Steele

Arkansas Water Resources Center Technical Reports

Wet and dry fallout at Fayetteville, Arkansas have been collected separately and analyzed since April, 1980. The precipitation-weighted-average pH for two yearly periods of rainfall were 4.72 (6/80-5/81) and 4.75 (6/81-5/82). This corresponds to a concentration of the acid ion, H+, of about 18 parts per billion (ppb). Pure water in equilibrium with the CO2 of the air would have a pH of 5.65 (2.2 ppb of H+). The range of pH during this two year period was 3.86-7.74(140-0 ppb H+) for the rainfall. Aqueous extracts of the dry fallout were always in the 6.75-7.87 pH range, i.e., neutral to …

Monitoring Of Groundwater Levels For Real-Time Conjunctive Water Management, Richard C. Peralta, Vince Mazure, Paul Dutram

Arkansas Water Resources Center Technical Reports

Water users in the Arkansas Grand Prairie wish to maintain sufficient groundwater levels to: insure adequate groundwater reserves for time of drought, protect themselves from litigation caused by wells going dry, and insure a sustained yield. Achievement of these goals requires regular measurement of groundwater levels. Review of monitoring practice and technology indicates that spring and fall measurements taken over the entire area using steel tape and acoustic device is preferred for most long range planning. Continuous monitoring is indicated for critical parts of the region where saturated thicknesses are small. Desirable attributes of a data collection/transmission system for such …

A Survey Of Soils Irrigated With Arkansas River Water, John T. Gilmour, H. D. Scott, R. E. Baser

Arkansas Water Resources Center Technical Reports

Interest in the use of Arkansas River water for irrigation has increased recently as land adjacent to the river is converted to crop production and river water is considered as an alternative to depleted underground supplies. Since the Arkansas River can contain elevated concentrations of sodium chloride, this study was designed to determine if soil conditions adverse to crop growth were developing where river water has been used. The impact of river water on sites where river water was used as either the sole source for up to 3 years or as a supplement to another surface source for up …

The Effects Of Forest Harvest On Water Quality And Aquatic Life (Phase I), Edmond J. Bacon

Arkansas Water Resources Center Technical Reports

A long term study on the effects of clearcut forest harvest and regeneration was conducted in a representative watershed of the Ouachita National Forest. Fourteen water quality parameters were analyzed to characterize baseline water quality. Water quality was classified as excellent. A total of 350 quantitative benthic samples and 15 ultraviolet light trap samples yielded 173 species of macroinvertebrates. Mean densities of macroinvertebrates ranged from 4,800/m2 to 23,040/m2 and averaged 12,499/m2 in the upper Little Missouri River. Twenty-two quantitative collections of fishes were made at representative riffles and pools. The average biomass estimates for riffles and pools were 5.69 kg/ha …

Hydraulic Analysis Of Surcharged Storm Sewer Systems, Don J. Wood, Gregory C. Heitzman

KWRRI Research Reports

Surcharge in a storm sewer system is the condition in which an entire sewer section is submerged and the pipe is flowing full under pressure. Flow in a surcharged storm sewer is essentially slowly varying unsteady pipe flow and methods for analyzing this type of flow are investigated. In this report the governing equations for unsteady fluid flow in pressurized storm sewers are presented. From these governing equations three numerical models are developed using various assumptions and simplifications. These flow models are applied to several example storm sewer systems under surcharge conditions. Plots of hydraulic grade and flow throughout the …

Climate Model For Winter Wheat Yield Simulation, Kenneth G. Hubbard, R.J. Hanks

School of Natural Resources: Faculty Publications

Winter wheat yields were simlulated by a model requiring climatic data as input for estimating crop evapotranspiration and phenological development. An assumed relationship between the winter wheat yields and the amount and timing of crop water use was optimized to simulate yields for two case studies: a single season, irrigated wheat study, and a multi-year, dryland wheat study. The model explained more than 90% of the variance of wheat yields in the irrigated study where total irrigation amounts varied between 0 and 55 cm. About 40% of the variance was explained for annual yields from a 21-year, dryland winter wheat …

Spatial And Temporal Variations In Long-Term Normal Percent Possible Solar Radiation Levels In The United States, Robert C. Balling, Randall S. Cerveny

School of Natural Resources: Faculty Publications

The purpose of this study was to analyze the time and space variations in long-term monthly-averaged daily percent possible solar radiation levels in the United States. Both principal components analysis and harmonic analysis were used to identify the influences of various synoptic-scale climatological phenomena on solar radiation receipt. Generally, an annual cycle was found with maximum percent possible radiation levels occurring in July. In many regions the temporal variance structure deviated from this general annual cycle. The results, which are useful in both theoretical and practical studies, lead to a better understanding of the climatology of solar radiation in the …

Land Use For Timber And Recreation: A Case Study In Victoria, Australia, Lawrence C. Merriam

Journal of the Minnesota Academy of Science

For many years the United States has had major problems in public land use for timber and recreation. Problems in Minnesota's Boundary Waters Canoe Area are an example. Australia is a country with Simi !tar concerns. The State Forests of Central Victoria, administered by the Forests Commission, were heavily burned m 1939. They now have regenerated to commercially mature stands, particularly of mountain ash (Eucalyptus regnans F. Muell.). Within 100 kilometers of the 3 million people in Melbourne, the forests are popular recreation sites. This paper reports on a study made for the Forests Commission aimed at the effective integration …

Interagency Hazard Mitigation: 90-Day Post Flood Recovery Progress Report, Hazard Mitigation Team (Utah)

Elusive Documents

As a result of an extended period of abnormally high precipitation, prolonged snow melt, and subsequent high water tales, Utahns, in 1983 suffered from landslides, debris flows, flooding, and a dam failure. On April 30, 1983, the President determined the Spanish Fork slide-dam and Thistle flood covering Utah, Carbon, and Emery Counties was of sufficient seventy and magnitude to issue a Major Disaster Declaration under Public Law 93-288. The incident period was not closed until July 1, 1983. By the time all flooding had ceased, nineteen additional counties (over 75% of Utah) had been included in the Declaration.
