Some International Approaches To Rat Control, Walter E. Howard

Great Plains Wildlife Damage Control Workshop Proceedings

There are many basic requirements concerning the political structure, financial support needed, proper organization, staff training, public education, laws and regulations, and the keeping of good records, which must be adequately considered before a rat control program can become successful. Likewise, there are also a number of basic principles concerning rodent control that must be understood and adhered to. Some villages in Korea and the country of Kuwait will be used as examples of new rat control approaches.

The Use Of Ultralight Aircraft For Aerial Control Of Coyotes, James E. Knight

Great Plains Wildlife Damage Control Workshop Proceedings

The changing complexion of modern animal damage control, coupled with the lack of funding available to government, has created the need for innovative methods of conducting control programs. Ultralight aircraft are presently being tested to determine their effectiveness, efficiency and safety for aerial gunning coyotes.

Rancher Use Of Compound 1080 Toxic Collars In New Mexico, Gary A. Littauer

Great Plains Wildlife Damage Control Workshop Proceedings

Twenty-three ranchers were trained and certified to use Compound 1080 in toxic collars to control coyote ( Ca nts l a tran s predation on sheep during a 2-year experimental program conducted by the New Mexico Department of Agriculture. Fifteen ranchers employed a total of 330 collars in field use. Two used collars in preventive control schemes and success was unknown. Thirteen used collars in corrective control (i.e. predation was in progress); 6 had collared lambs attacked and killed by coyotes; 4 had 1 or more collars punctured by coyotes and in 1 case a bobcat; 3 solved specific coyote …

The purpose of this study was to determine the viability of rabies virus in brains and salivary glands of rabid striped skunk (Mephitis mephitis ) carcasses exposed to different controlled temperatures.

Workshop-Discussion Session, Joesph M. Schaefer

Great Plains Wildlife Damage Control Workshop Proceedings

The purpose of the workshop-discussion session was to establish a list of ideas that would provide the best focus and direction to improve wildlife damage control programs. During this session the Nominal Group Technique (NGT) (Delbecq et al. 1975) was used to: 1) identify and rank obstacles that limit the effectiveness of wildlife damage control efforts, and 2) generate possible solutions to the most important obstacles. This format allowed equal and full participation and was successful in generating many original ideas.

Reducing Goat Losses To Predators: Past Vs. Present Producers In Texas, Jerry H. Scrivner

Great Plains Wildlife Damage Control Workshop Proceedings

The purpose of this study was to gather information regarding the application and economic implications of predator control and husbandry methods used by 104 past and 103 present Angora goat producers in Texas. Of 7 techniques [(1) predator control by ranchers, (2) support of private or government trappers, (3) night penning of livestock, (4) confinement or semi-confinement kidding, (5) extra checking on goats, (6) the use of guard dogs, and (7) the use of scare devices] ranchers use to reduce predation losses, present producers used significantly more techniques than did past producers. Also, present producers generally implemented each technique to …

Rodent Populations And Crop Damage In Minimum Tillage Corn Fields, Richard E. Young, William R. Clark

Great Plains Wildlife Damage Control Workshop Proceedings

No-till and disked cornfields were examined in southwest Iowa to determine small mammal population densities, movements, and impacts of rodent depredations on corn seedlings. Two replicates of the treatments corn planted into. corn stubble, corn planted into chemically treated sod, and corn planted into spring-disked fields were studied during the 1982 and 1983 growing seasons. Grids of 100 Sherman live traps were established at the edge and middle of each field to determine rodent densities and document possible encroachment of small mammals from nearby habitats. Trapping experiments were conducted for 6 consecutive days during May, August, and November. To assess …

Rodent Management On The Northern High Plains, Ardell J. Bjugstad

Great Plains Wildlife Damage Control Workshop Proceedings

Rodent damage on the Northern High Plains has caused estimated economic losses of millions of dollars per year. The Columbian ground squirrel (Citellus columbianus) caused $800,000 damage in Montana during 1973, whereas prairie dogs (Cvnomvs ludovicianus) caused a loss of $2 million in South Dakota during 1980. Initial control of prairie dogs in South Dakota would cost approximately $1.2 million dollars and maintenance measures would be needed about every third to fifth year depending on percentage success of the initial control and management practices thereafter. Results of a cost-benefit study in South Dakota indicated that the annual maintenance control rate …

The Microcomputer And Kansas Wildlife Damage Reports, Martin Ottenheimer

Great Plains Wildlife Damage Control Workshop Proceedings

When F. Robert Henderson, the Extension State Leader of Kansas' Wildlife Damage Control Program, asked me for assistance in setting up a microcomputer system that would enable him to organize and analyze wildlife damage reports, I was surprised. "Certainly," I thought, "it's not because I am a social anthropologist and in my travels around the world I deal with some pretty wild life" No, Bob knew about my work with microcomputers in Anthropology and since we have been friends for some years he also knew that I would talk with him about the problems in using microcomputers. He also knew …

Guardian Dog Research In The U.S., John C. Mcgrew

Great Plains Wildlife Damage Control Workshop Proceedings

Research on the use and effectiveness of guardian dogs has been conducted since 1977 at 3 locations in the U.S.: the Livestock Dog Project (Amherst, MA), the U.S. Sheep Experiment Station (Dubois, ID), and Colorado State University (Ft. Collins). Their findings are quite consistent: dogs guard sheep and goats directly, i.e., they respond aggressively to predators, chasing them away when necessary, then returning to the flock. This aggressive response toward predators is apparently defense of personal space rather than territorial defense. The development of attentiveness toward sheep, beginning early in life, is probably the most important aspect of training a …

A Microsystem Sediment-Water Simulation Study For The Proposed Jordanelle Reservoir, Heber City, Utah, United States Department Of The Interior, Bureau Of Reclamation

Water

The technique of microsystem sediment-water simulation was used to predict water quality data for the proposed Jordanelle Reservoir, Heber City, Utah. Simulation microsystems were prepared for four sites located in the north arm of the reservoir basin including two sites located in an abandoned acid mine tailings pond. Data obtained from the tailings pond microsystems indicated that low pH water and high trace metal concentrations will exist in the north arm of the reservoir. These data suggested that some kind of membrane or compacted earth lining will be necessary to seal and contain the mine spoilage. Other sites in the …

The Effects Of Dredged Materials On The Copeod, Acartia Tonsa, Renee Suzanne Crouch

Biological Sciences Theses & Dissertations

A study was conducted to determine the potential impact of open ocean disposal of sediments dredged from a highly industrialized seaport. Sediments from three potential dredge sites along the Southern Branch of the Elizabeth River, Hampton Roads, Virginia were evaluated for acute toxicity. The suspended particulate fractions of dredged materials were tested in a series of 96-hour, static bioassays using the calanoid copepod, Acartia tonsa Dana. Significant mortalities were observed for all three sites with the sediments from the most heavily industrialized site producing immediate and severe mortality. Analysis of results indicates that mortality was highly related to the volatile …

Water Requirement For Coal Slurry Transportation, David T. Kao, Sandra L. Rusher

KWRRI Research Reports

The amount of water required for coal slurry transportation is a function of the coal properties and the magnitude of coal movement. The pipeline system characteristics and the method of slurry preparation also affects the overall water requirement of the system. In the present study methodologies are developed based on reported and modified coal slurry flow correlation equations to determine the quantity of water needed under various coal transport and flow conditions. Auxiliary water requirements including start-up and flushing water storage; related evaporation and seepage losses are also included. A computer program and several monographs are presented to provide a …

KWRRI Research Reports

Information on fluorescent dyes used for water tracing and the results of six studies are reported. Optical brightener, direct yellow, fluorescein, rhodamine (WT), and other dyes are described and the procedures employed in their use ·in the field and in equilibration experiments are discussed. Three of the six studies consisted of investigations of the equilibration with passive detectors of three of the dyes. The absorption of optical brightener on fabric detectors was apparently linear with concentration and with immersion time, while detectors became rapidly saturated with direct yellow. Equilibrium of fluorescein on charcoal detectors with an elutriating solution was not …
