Control Of Microtus In Two Damage Situations, Andrew Radvanyi

Eastern Pine and Meadow Vole Symposia

In Canada the potential exists of over a million dollars girdling damage loss per year caused by small mammals to fruit trees in each of the four major orchard areas of British Columbia, Ontario, Quebec and Nova Scotia. Such annual losses continue to occur despite the existence of methods developed which could largely eliminate a large percentage of such losses at a fraction of the costs currently being spent on attempts to control small mammal populations (primarily meadow voles (Microtus pennsylvanicus) in orchard situations. In this paper I propose to outline briefly the developmental studies conducted by the …

Remarks To Be Presented At The First Eastern Pine And Meadow Vole Symposium, Merle H. Markley

Eastern Pine and Meadow Vole Symposia

A Rebuttable Presumption Against Reregistration has been issued against endrin. It is my own opinion that: First endrin should be critically examined, use by use, with respect to effectiveness and alleged hazard to non-target animals, be they pets, domestic stock or wildlife; and secondly, that a careful and complete review be made of all economic benefits against the hazards identified in the earlier review. The notice which appeared in the Federal Register emphasized the occasional harmful aspects of use and failed to give much or any credence to benefits. Certainly there must be some value to the grower and financial …

The Need For An Integrated Control Strategy For Orchard Mouse Damage, Robert Stehn, Elizabeth Johnson, Milo Richmond

Eastern Pine and Meadow Vole Symposia

During the last six years the N.Y. Coop. Wildlife Research Unit has been involved in research on pine voles. Projects have included studies of reproduction in the laboratory, population biology in orchards and testing of pine vole control toxicants. Field work has been restricted to a few orchards in Ulster and Orange counties in the Hudson Valley. Therefore some of the results may reflect local conditions and should be regarded as preliminary in nature. Work involving control procedures has indicated that hand baiting with anticoagulant pellets under previously established bait stations averages 85 percent reduction in pine vole numbers. Anticoagulant …

Landsat Linear Trend Analysis - A Tool For Groundwater Exploration In Northern Arkansas, H. C. Macdonald, Kenneth F. Steele, Elizabeth Gaines

Arkansas Water Resources Center Technical Reports

Intelligent development of groundwater resources is a process that requires a thorough understanding of the availability and movement of groundwater. In northern Arkansas knowledge of the deep aquifers is fairly limited, perhaps because economic factors and uncertain yields have discouraged exploitation. The development of these deeper aquifers to their fullest potential as reliable water sources depends on the delineation of high yield areas, a process that may be facilitated by linear trend analysis as outlined in this study. Satellite and photolineament maps of the 13 counties were prepared by use of LANDSAT images and Agricultural Stabilization and Conservation Service photo …

Hydrology And Water Quality In The Central Kentucky Karst: Phase 1, James F. Quinlan, Donald R. Rowe

KWRRI Research Reports

Study of springs and cave streams has shown that heavy metal-rich effluent from a wastewater treatment plant can be traced to Hidden River Cave (beneath the city of Horse Cave) and thence 4 to 5 miles north to a group of 39 springs at 14 locations along a 5-mile reach of Green River. Nickel, chromium, copper and zinc in these effluent-bearing springs are in concentrations of as much as 30 times greater than other springs upstream and downstream from this reach, 20 times greater than the Green River, and 60 times greater than in shallow domestic wells between Horse Cave …

Saltland And What To Do About It, C V. Malcolm

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

Saltland can be conveniently divided into three main types on the basis of cause. Within each type their is great variation, and the types may merge or overlap.

The three aims of a saltland treatment programme are; reduce the groundwater levels or seepage flows as much as possible,reduce the capillary action which brings salt to the surface, and to revegetate the soils with the most useful plants that can survive.

The European Wasp : A New Threat To W.A, Department Of Agriculture, Western Australia

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

The European wasp was detected in Western australia for the first time in January and February 1977 in the metropolitan suburbs of Mosman Park, Cottesloe and Attadale.

So far it has only been found within an area of 8 km radius from Fremantle but the outer boundries of the infestation are still uncertain.

It is Department of agriculture policy to eradicate the European wasp, if possible, and to destroy all nests detected.

Some Basics Of Marron Production, Department Of Agriculture, Western Australia

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

marron are native to the South-West of Western Australia, and are keenly sought by inland fisher-men. However, supplies do not equal the apparent demand.

One solution is to cultivate marron in farm dams, or more intensively as a commercial enterprise.

This article suggests a few guidelines for marron production.

A Stream Survey Of Riley Creek, Coles County, Illinois, Using Macroinvertebrates As Indicators Of Organic Pollution, Joseph R. Rowe

Masters Theses

A stream survey of Riley Creek in Coles County Illinois, was undertaken to determine ecological trends and the qualitative status of the aquatic community throughout the course of the stream.

The survey encompassed the entire length of Riley Creek from the area of its status as an intermittant waterway to its confluence with Cassel Creek. Sampling periods included the months of April, May, June, July, October and November.

Macroinvertebrate collections were made at six locations along the stream approximately equidistant from each other. The organisms were assigned tolerance levels as designated by the Illinois Environmental Protection Agency.

Rural Domestic Water System Peak Flows And Design Innovations, Optimal Water Planning Series, Trevor C. Hughes, Yukio Kono, Ronald Canfield

Reports

Planning engineers commonly use generous factors of safety for peak flow estimates in urban water supply systems both as a hedge against unforeseen growth and because economies of scale result in relatively low user costs even with such reserve capacity. Transplanting of such design criteria into the rural setting, however, simply does not work. The low density portions of rural domestic systems require very realistic design criteria or the construction costs become infeasible for the small number of customers involved. Peak instantaneous flow rates in a Utah rural system were measured continuously during two summers on three dead-end lines serving …

Series Intermittent Sand Filtration Of Wastewater Lagoon Effluents, David W. Hill, J. H. Reynolds, D. S. Filip, E. J. Middlebrooks

Reports

Previous researches have found single stage intermittent sand filtration to be a feasible and economic means of upgrading wastewater lagoon effluent to meet future standards. However the major constraint on their use has been the length of the filter runs. Laboratory scale and pilot-scale series intermittent sand filtration of wastewater lagoon effluents has been found to substantially increase the length of filter runs as well as produce a high quality effluent able to meet future standards. Higher loading rates were round to be possible with series intermittent sand filtration. The operation consistently produced an effluent meeting present Utah “Class C” …

Also, with the exception of mercury, concentrations of heavy metals did not differ significantly in the agricultural and industrial areas.

Effect Of Deforestation By The Douglas-Fir Tussock Moth On The Quality Of Streamflow And Stream Productivity Parameters, Martin Ed Hicks

All Master's Theses

The purpose of this study was to determine if deforestation by a recent outbreak of Douglas-fir tussock moth and logging of such deforested timber has had any effect on stream water quality. To determine this, seven different watersheds of three types were examined. The three types were: undamaged watersheds as controls, watersheds with deforestation and watersheds with deforestation where the timber was subsequently logged. Twenty-four variables were used to determine water quality. Included were seven biological and seventeen chemical variables.

In general, the results indicate only seasonal fluctuations and differences between watersheds due to inherent properties of individual watersheds. Increased …
