Black Bear Damage In The Mississippi Alluvial Valley, Thomas H. White Jr., Catherine C. Shropshire, Mike Staten Nov 1995

Black Bear Damage In The Mississippi Alluvial Valley, Thomas H. White Jr., Catherine C. Shropshire, Mike Staten

Eastern Wildlife Damage Management Conference: 7th (1995)

We surveyed 62 hunting clubs in the batture of the Mississippi River in Arkansas and Mississippi to determine the extent and severity of black bear (Ursus americanus) damage. Bear damage was more prevalent in Arkansas (70.6%) than in Mississippi (11.8%). Damage to deer- stands was most common (43.8%), followed by damage to buildings (22.9%), getting in garbage (12.5%) and damage to wildlife food plots (10.4%). Cost estimates of bear damage averaged approximately $40 per incident over the past 5 years. Most (90.9%) clubs rated bear damage as either a slight nuisance or not important at this time, and …


Blackbirds And Starlings Killed At Winter Roosts From Pa-14 Applications, 1974-1992: Implications For Regional Population Management, Richard A. Dolbeer, Donald F. Mott, Jerrold L. Belant Nov 1995

Blackbirds And Starlings Killed At Winter Roosts From Pa-14 Applications, 1974-1992: Implications For Regional Population Management, Richard A. Dolbeer, Donald F. Mott, Jerrold L. Belant

Eastern Wildlife Damage Management Conference: 7th (1995)

The surfactant PA-14, registered with the U.S. Environmental Protection Agency (EPA) in 1973 by the federal Animal Damage Control (ADC) program, was used for 19 years (1974-1992) for lethal control of roosting blackbirds (Icterinae) and European starlings (Sturnus vulgaris) in the United States. In 1992, the ADC program withdrew the registration of PA-14 because of costs required to provide additional EPA-requested data. There were 83 roosts encompassing 178 ha treated with 33,300 L of PA-14 from 1974-1992. An estimated 38.2 million birds (48% common grackles [Quiscalus quiscula], 30% European starlings, 13% red-winged blackbirds [Agelaius phoeniceus …


Comparison Of Predation Rates On Wild Turkey Hens Between Two Forest Ecosystems In Mississippi, Michael J. Chamberlain, Darken A. Miller, Bruce D. Leopold, George A. Hurst Nov 1995

Comparison Of Predation Rates On Wild Turkey Hens Between Two Forest Ecosystems In Mississippi, Michael J. Chamberlain, Darken A. Miller, Bruce D. Leopold, George A. Hurst

Eastern Wildlife Damage Management Conference: 7th (1995)

Because of increases in predator populations, concern has arisen about effects on wild turkey (Meleagris gallopavo ) populations. We examined differences in predation of adult hens between 2 forested areas in Mississippi. Twin Oaks Wildlife Management Area (OAKS), located in the Mississippi Alluvial Valley, is a 2,302 ha tract of mature bottomland hardwood forest surrounded on 3 sides by soybean fields. Tallahala Wildlife Management Area (TWMA) is a 14,410 ha mixed forest in central Mississippi and is part of a large, forested ecosystem. Hens were captured, fitted with transmitters, and monitored by telemetry, 1990-1994 on TWMA (n = …

The Effectiveness Of A New Mole Repellent For Preventing Damage To Lawns By Eastern Moles, Glenn R. Dudderar, Stacey Tellman, Dale K. Elshoff

Eastern Wildlife Damage Management Conference: 7th (1995)

A new product containing 65% castor oil with the trade name Mole-Med was evaluated for its effectiveness in repelling eastern moles (Scalopus aquaticus) from lawns. Seven lawns in southern Michigan during September, 1993 was selected as preliminary test sites, and the ridges over mole tunnels in the lawns were flattened each day for 3 days. If some existing and new ridges were raised each day, the site was classified as having mole activity and continuing damage. The repellent was then applied according to label directions, and ridges above mole tunnels were flattened as described previously. If no tunnels …


Evaluation Of The Yard Gard Ultrasonic Yard Protector For Repelling White-Tailed Deer, Paul D. Curtis Nov 1995

Evaluation Of The Yard Gard Ultrasonic Yard Protector For Repelling White-Tailed Deer, Paul D. Curtis

Eastern Wildlife Damage Management Conference: 7th (1995)

Ultrasonic devices are marketed for pest control because some manufacturers believe they possess properties aversive to animals. However, there is little evidence that ultrasound is more aversive to animals than is audible sound. In this study, we examined the efficacy of the Yard Gard ultrasonic device for deterring deer (Odocoileus virginianus) from feeding on apples. Four deer feeding stations were established at private residential properties with a history of deer damage to ornamental plants, so that control (A I and B 1) and experimental (A2 and 132) stations existed at each site. Apples were placed at each feeding …


Black Bear Damage Management In Washington State, Georg J. Ziegltrum, Dale L. Nolte Nov 1995

Black Bear Damage Management In Washington State, Georg J. Ziegltrum, Dale L. Nolte

Eastern Wildlife Damage Management Conference: 7th (1995)

Black bears (Ursus americanus) foraging on trees can be extremely detrimental to the health and economic value of a timber stand. A supplemental feeding program to reduce bear damage is coordinated by the Washington Forest Protection Association's Animal Damage Control Program (ADCP). A brief overview of the ADCP is provided along with a description of bear damage and the supplemental feeding program. Success of the feeding program is demonstrated by an increasing participation and its general acceptance by the public. Timber producers placed over 400 thousand pounds of pellets in 700 feeding stations this past year.

Groundwater Study: Toyota Motor Manufacturing, Usa Georgetown, Kentucky, Gary Felton, Lyle V. A. Sendlein, Teri Dowdy, Daryl Hines Nov 1995

Groundwater Study: Toyota Motor Manufacturing, Usa Georgetown, Kentucky, Gary Felton, Lyle V. A. Sendlein, Teri Dowdy, Daryl Hines

KWRRI Research Reports

An eighteen month study of the Toyota Motor Manufacturing (TMM) plant site and the surrounding area was undertaken. The basic charge for this project was to characterize the groundwater that is potentially impacted by the TMM plant site. This included occurrence, flow direction, and, if possible, velocity. Because the area is karstified (has sinkholes, springs, caves, etc.) surface water and groundwater are intimately connected and, hence, surface water was frequently an important component of this work.

Data from TMM construction plans and monitoring work done subsequent to construction were elicited from the various repositories within the TMM infrastructure. Aerial color …


The Effect Of Sulfur And Phosphorus Compounds On Supported Platinum Catalyst Activity, Yi Wang Oct 1995

The Effect Of Sulfur And Phosphorus Compounds On Supported Platinum Catalyst Activity, Yi Wang

Dissertations

The effect of sulfur poisoning on the activity of catalysts containing 1.5% platinum supported on γ-Al2O3, TiO2, ZrO2, or SiO2 was investigated in this study. These four catalysts were aged with 100 ppmv H2S in air at 400°C for 24 hours to determine the effect of sulfur poisoning under oxidizing conditions. In separate experiments, 1.5% Pt/γ-Al2O3 catalyst was aged in nitrogen containing 100 ppmv H2S to obtain a frame of reference for non-oxidizing conditions.

The oxidation of 1% CO, 1% methane, and 1% propane …


Effectiveness Of Sediment Control Structure : Reducing Nonpoint-Source Pollution Entering A Rural Housing Development Lake In Mercer County, Pennsylvania, Elaine K. Brenner Oct 1995

Effectiveness Of Sediment Control Structure : Reducing Nonpoint-Source Pollution Entering A Rural Housing Development Lake In Mercer County, Pennsylvania, Elaine K. Brenner

Theses

For the past two decades, water quality of both natural and man-made lakes has been a major environmental concern. Numerous studies suggest that land use patterns and/or storm water runoff are major factors in nutrient loading and bacterial contamination of freshwater lakes. In 1986, the Property Owners Association at Lake Latonka in Jackson Center, Pa., installed three sediment control structures in an attempt to reduce the amount of nonpoint-source pollution entering the lake. The Association installed a fourth structure in 1988. It has yet to be determined if any improvement in the water quality has occurred due to the control …


Investigation Into Fracture Behavior And Longevity Of Pneumatically Fractured Fine-Grained Formations, Heathe Ann Hall Oct 1995

Investigation Into Fracture Behavior And Longevity Of Pneumatically Fractured Fine-Grained Formations, Heathe Ann Hall

Theses

This study investigates volume changes in fine-grained soil formations and their effect on pneumatically induced fractures. Pneumatic fracturing is an enhancement technology for in situ remediation of hazardous waste sites, which increases the formation permeability by creating fractures. A number of formation properties and environmental conditions which affect fracture aperture were identified in this study.

Laboratory experiments were performed with control devices to investigate idealized fracture flow under linear and radial flow geometries. These tests exhibited cubic law behavior, and gas compressibility was seen as a measurable effect. A horizontal infiltrometer device was successfully developed to induce and control volume …


Ultrasonic Enhanced Soil Washing, Chu-Feng Wei Oct 1995

Ultrasonic Enhanced Soil Washing, Chu-Feng Wei

Theses

Soil washing is an ex-situ process employing chemical and physical extraction and separation techniques to remove a broad range of organic, inorganic, and radioactive contaminants from soils. This research investigates the enhanced soil washing of a high level Polycyclic Aromatic Hydrocarbons (PAHs) contaminated coal tar soil by the application of ultrasound energy coupled with surfactant (soap) emulsions and attempts to optimize pollutant removal from contaminated soils. The non-ionic surfactant, octyl-phenyl-ethoxylate, was used as the surfactant.

Using bench-scale experiments, the magnitude of the ultrasonic enhancement was evaluated by changing the process parameters, such as ultrasonic power density, Dwell (extractor residence time), …


Catalytic Oxidation Of Trace Concentrations Of Trichloroethylene Over Cr2o3 And 5% Cr2o3 On ?-Al2o3, Soyoung Myung Oct 1995

Catalytic Oxidation Of Trace Concentrations Of Trichloroethylene Over Cr2o3 And 5% Cr2o3 On ?-Al2o3, Soyoung Myung

Theses

This research addressed the ability of Cr2O3 and 5% Cr2O3/γ-Al2O3 to catalytically oxidize trichioroethylene (TCE). Various types of Cr2O3 catalysts were compared with Pt, CuO and Fe2O3 which were previously tested in our laboratory. A number of sample catalysts containing 5% Cr2O3 on γ-Al2O3 were synthesized for this research. Different procedures were evaluated in the synthesis in order to find which procedure gives the most active catalyst. The oxidation of TCE was used as a diagnostic reaction to …


Black Bear Damage To Lodgepole Pine In Central Oregon, Victor G. Barnes Jr., Richard M. Engeman Oct 1995

Black Bear Damage To Lodgepole Pine In Central Oregon, Victor G. Barnes Jr., Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

Black bear (Ursus amerlcanus) damage to 108 lodgepole pine (Pinus contorta) trees was found in a mixed conifer habitat in central Oregon. No trees of three other conifer species were injured. Eighty-nine percent of the damage occurred in the same year. Nearly 20% of the freshly damaged trees had bark removed from more than 75% of the circumference and, judging from the fate of trees damaged in prior years, probably succumbed.
