Using Aircraft For Controlling Blackbird/Sunflower Depredations, Larry L. Handegard

Vertebrate Pest Conference Proceedings: 13th (1988)

Although not a new idea, using aircraft to control blackbird damage to sunflowers has provided some relief for sunflower growers in North Dakota. The numerous scaring devices and limited frightening agents have not proven effective in controlling blackbird damage to sunflowers. In response to a congressional directive to provide assistance in controlling blackbird/sunflower depredations in North Dakota, a blackbird hazing program was developed. The program utilized fixed-wing aircraft and shooting to expedite the migration of blackbirds through North Dakota.

Controlling Shiny Cowbirds In Puerto Rico, Jon F. Heisterberg, Fernando Nunez-Garcia

Vertebrate Pest Conference Proceedings: 13th (1988)

A program to trap and remove shiny cowbirds (Molothrus bonariensis) was conducted during two successive passerine nesting seasons at Roosevelt Roads Naval Station in eastern Puerto Rico. It sought to improve existing trapping techniques and to determine the effect cowbird removal has on the reproductive success of the endangered yellow-shouldered blackbird (Agelaius xanthomus). Decoy traps of two basic designs were used to capture 2449 cowbirds in 1162 trap-days (average 2.l/trap-day) in June-September 1985 and 850 cowbirds in 1571 trap-days (average 0.5/trap-day) in March-August 1986. The lower capture rate in 1986 suggests that cowbirds removed in 1985 were not being replaced …

Alleviating Nuisance Canada Goose Problems With Acoustical Stimuli, Donald F. Mott, Shirley K. Timbrook

Vertebrate Pest Conference Proceedings: 13th (1988)

Alarm/distress calls of Canada geese (Branta canadensis) were evaluated by themselves and in combination with racket bombs to determine their effectiveness in frightening Canada geese from nuisance situations at 2 Corps of Engineers campgrounds in Tennessee. Results based on goose censuses showed a significant (P<0.05) reduction in goose numbers from nontreatment to treatment periods at both sites. Goose numbers were reduced an average of 71% when the calls alone were used. The combination of the calls and the racket bombs produced a 96% reduction in goose observations. Although a reduction in geese was observed during the treatment periods, continual harassment would appear to be necessary as reinvasion was noted after treatment was stopped. The scarcity of alternate feeding and loafing sites may have contributed to this lack of long-term control.

Characteristics Of Bird-Resistance In Agricultural Crops , Roger W. Bullard

Vertebrate Pest Conference Proceedings: 13th (1988)

The use of biochemical or morphological genetic traits in a crop to protect ripening seeds or grain from bird damage remains a promising tool under certain situations. Research on bird-resistance in crops has focused on grain sorghum, corn, sunflower and rice. This crop protection method involves feeding behavior of granivorous birds and its effectiveness depends on the availability of preferred alternate foods. That is, bird-resistant traits provide protection to the crop when other food choices are readily available; however, when alternate food is scarce or high bird populations create serious feeding competition, they are less effective. Several practical factors (i.e., …

Behavioral Response Of Cattle Egrets To Population Control Measures In Hawaii, David P. Fellows, Peter W. C. Paton

Vertebrate Pest Conference Proceedings: 13th (1988)

We monitored behavior of cattle egrets (Bubulcus ibis) during a population control program to reduce egret-aircraft strike hazards from a small heronry near the Hilo, Hawaii, airport. Results verified that attempts to move egrets from undesirable roost sites should be undertaken before nesting begins. Although possibly compounded by previous treatments, our observations also indicate that 1) egrets may abandon a new roost in response to a few dead egrets placed in clear view around the roost, and 2) shooting at egrets as they attempt to land at a traditional feeding site causes long-term avoidance of the area. Rapid repopulation after …

Management Of Fruit Bat And Rat Populations In The Maldive Islands, Indian Ocean, Richard R. Dolbeer, Lynwood R. Fiedler, Hussain Rasheed

Vertebrate Pest Conference Proceedings: 13th (1988)

The introduced black rat (Rattus rattus) and the endemic giant fruit bat (Pteropus giganteus ariel) are serious depredators of coconuts and fruits, respectively, in the Maldives. Differences in reproductive rate between rats (high) and bats (low) must be considered in implementing control programs. We estimate a rat population can fully recover from an island-wide reduction of 90% in less than 6 months. In contrast, a bat population may require 6 years to recover from a 90% reduction. Crown-baiting of coconut palms with anticoagulant rodenticides is effective in reducing rat damage, but villagers have been reluctant to adopt recommended baiting programs, …

The Impact Of Wildlife Damage On Wildlife Management Programs In Wisconsin, Scott R. Craven

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Wildlife damage caused by species normally managed as game animals or furbearers should be of major concern to wildlife managers and various user groups: hunters, trappers, and other outdoor recreationists. Real or potential damage may be used as an important factor in determining population levels, harvest goals, and distribution of white-tailed deer and Canada geese in Wisconsin. In any state where private land and agriculture are important, such a strategy could reduce wildlife populations and associated recreational opportunities. Recent surveys in Wisconsin have quantified the amount and distribution of deer, goose, and turkey damage in Wisconsin. These data allow …

Characteristics Of Damage By Vertebrate Pests To Groundnuts In Pakistan, Joe E. Brooks, Ejaz Ahmad, Iftikhar Hussain

Vertebrate Pest Conference Proceedings: 13th (1988)

Vertebrate pest damage to groundnut (Arachis hvpogea) was assessed at harvest in 164 fields selected along road transects in Pakistan. Overall damage in these fields was estimated at 5.3 %, of which the lesser bandicoot rat (Bandicota bengalensis) accounted for 2.4%, the short-tailed mole rat (Nesokia indica) caused 1.0%, and the wild boar (Sus scrofa) caused 0.9%. Desert hares (Lepus nigricollis). crested porcupines (Hystrix indica) and house crows (Corvus splendens) together accounted for the remaining 1.0% damage. The damage characteristics of each species are described. Observations indicated that visual above-ground examination of plants for damage underestimated the actual loss because …

A Decade Of Use Of Livestock Guarding Dogs, Raymond Coppinger, Lorna Coppinger, Gail Langeloh, Lori Gettler, Jay Lorenz

Vertebrate Pest Conference Proceedings: 13th (1988)

Results from a ten-year study of livestock guarding dogs show that the dogs are an effective tool for reducing predation. Average reduction attained by five strains of dogs (Anatolian Shepherds, Maremmas, Shar Planinetz, Anatolian/ Shars, Maremma/Shars) was 64%, with predation reduced to zero for 53% of reporting producers in 1986. Variations in trustworthy, attentive and protective behavior of the dogs were breed-specific, and offer mechanisms for improving the system.

Photographic Records — Their Importance In Today's Environmentally Sensitive Bird Management Programs, Charles W. Areson

Vertebrate Pest Conference Proceedings: 13th (1988)

We are living in a day of change. Environmental awareness is a part of our everyday life in a way unprecedented in history. The courts, in their infinite wisdom, have initiated the joint and several liability (deep pocket) rules that make everyone at risk in almost all situations. Bird management programs, by their very nature, are extremely sensitive. Any project, if not evaluated, planned, carried out, and documented properly can result in adverse regulatory agency action, bad publicity, and even fines or lawsuits. Proper photographic documentation can play a vital part in helping to provide the necessary records to help …

Innovative Approaches In The Control Of Quelea, Ouelea Auelea Lathimii. In Zimbabwe, Mike Lagrange

Vertebrate Pest Conference Proceedings: 13th (1988)

Ever since crops have been grown, quelea have been a threat to summer subsistence crops and winter commercial wheat/barley cropping in Zimbabwe. Control techniques spraying toxicant Queletox through ground spray units and aircraft, developed in Zimbabwe, have produced 90% kills keeping the level of depredation down to acceptable levels. Zimbabwe, like most developing countries, faces protein shortages, and utilization of dead quelea by the rural population has always occurred even from sprayed colonies despite repeated warnings of possible side effects. Traditionally quelea have been sold on the black market for 10-20 Zimbabwe cents/bird and recently a far wider potential, even …

Controlling Wildlife Damage: Can Computers Help?, Leanne W. Las Arow

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Expert systems, a new computer field, is presented as a method to make computers more useful and professionally relevant. Expert systems technology is discussed and is demonstrated to be available and affordable. A typical wildlife damage control problem is presented: species identification of a burrowing pest from a verbal description of a mound or burrow. Development of the expert system, BURROW, is outlined in step-by-step fashion, from statement of the problem, through translating knowledge into rules, to testing and review. Emphasis is placed on encouraging others to write simple expert systems to solve routine problems.

Flocoumafen -- A New Anticoagulant Rodenticide , M. Lund

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Flocoumafen is a new anticoagulant rodenticide with an acute toxicity between that of bromadiolone and brodifacoum. It has performed well in field tests against house mice and susceptible as well as resistant brown rat populations. Danish lab tests reveal a considerable variation in susceptibility between rodent species and indicate that practical problems in the control of certain Scandinavian bromadiolone-resistant house mouse populations may arise shortly after introduction.

Comparative Evaluation Of Tamper-Proof Mouse Bait Stations, Karl D. Morris, Dale E. Kaukeinen

Vertebrate Pest Conference Proceedings: 13th (1988)

A method for the evaluation of mouse control using tamper-proof mouse bait stations was developed and efficacy trials conducted to determine if house mice (Mus musculus) would visit and consume rodenticidal baits located within these stations. All stations were rapidly investigated by mice. Variation seen between the individual stations related to animal variation and did not appear to be related to differences in the stations themselves. Station placement was more critical to mouse investigation and subsequent bait consumption from the station than were the various features used to prohibit non-target access.

An Evaluation Of Modified 4-Aminopyridine Baits For Protecting Sunflower From Blackbird Damage, C. Edward Knittle, John L. Cummings, George M. Linz, Jerome F. Besser

Vertebrate Pest Conference Proceedings: 13th (1988)

Bait preference studies with red-winged blackbirds (Agelaius phoeniceus) in North Dakota sunflower fields indicated that sunflower seeds and a combination of sunflower seeds and chopped corn (MIX) were more successful in producing affected blackbirds, primarily red-winged blackbirds, than pearl barley or chopped corn used separately. A subsequent study compared the effectiveness of commercial Avitrol FC Corn Chops-99S to 4-aminopyridine-treated MIX-99S baits for reducing blackbird damage to ripening sunflower. Both baits significantly reduced damage in fields nearest a blackbird roost (within two miles), but were largely ineffective in fields farther than two miles from a roost. The ramifications of these results …

Environmental Assessment Of Las Vegas Wash And Lake Mead Artificial Wetlands Demonstration Project, John R. Baker, R. M. Gersberg, U.S. Environmental Protection Agency

Publications (WR)

The effective use of artificial wetlands for treatment of municipal wastewater is well documented; however, design and economic data for artificial wetlands development are limited (Gersberg et al., 1984a). This is due partly to regional differences in climate, soils, and vegetation and partly to the desired waste treatment. As a result, specific treatment levels and cost benefits relative to the use of an artificial wetlands for a particular site cannot be evaluated adequately without a pilot demonstration project. Las Vegas Wash receives sewage effluent from the Las Vegas metropolitan area and has been designated as a wetlands community park. Las …

Comparative Adsorption Studies On Clay Soils, Prasanna R. Mysore

Theses

An investigation has been made to study clay as sorbent in the treatment of the hazardous contaminants of potential sludge leachate emanating from industrial landfills.

Experimentally was studied six highly toxic and hazardous chemicals, which include: phenol, aniline, cyclohexanol, cyclohexanone, cresol and monochlorophenol. Vermiculate, Kaolinite, Attacote and Hectorite clays were studied as the sorbent material. Removal of organic pollutants were measured using a total organic carbon analyzer (TOC).

Results indicate that these clays can be used for some treatment of the above mentioned organic compounds. The study shows that removal of organic pollutants by clay depends on several factors, such …

Seasonal Variations In The Diurnal Characteristics Of Heavy Hourly Precipitation Across The United States, Julie A. Winkler, Brent Robert Skeeter, Paul Yamamoto

School of Natural Resources: Faculty Publications

Hourly precipitation data from 1967 to 1983 for the conterminous United States were harmonically analyzed in order to document the diurnal variability of several categories of heavy precipitation during winter, spring, summer, and autumn. The analysis revealed that the diurnal characteristics of hourly precipitation vary considerably with season, geographic region, and precipitation intensity. During winter and spring, a weak, later-morning frequency maximum prevails for the lightest (2.5-6.2 mm h-1) precipitation category. As intensity increases (to 6.3-12.6, 12.7-25.3 and >25.4 mm h-1), the amplitude of the diurnal cycle also increases, and a nocturnal maximum becomes apparent across much of the eastern …

Small Mammal Responses To Roadside Habitat Management In South Central Minnesota, Jeffrey W. Grimm, Richard H. Yahner

Journal of the Minnesota Academy of Science

Responses of small mammals to management of roadsides in south central Minnesota were examined from August-October in 1980 and 1981. The Minnesota Department of Natural Resources established and maintained vegetation along portions of these roadsides by planting Bromus inermis and Medicago sativa as nesting cover for ring-necked pheasants (Phasianus colchicus) and with infrequent mowing. Landowners or state and county transportation departments maintained other roadside areas by frequent mowing of native vegetation. Mowing of roadsides had a negative effect on abundance of Blarina brevicauda, Peromyscus leucopus, Microtus pennsylvanicus, and Mustela erminea during both summer and autumn and on abundance of Peromyscus …

Seasonal Variations In Water Quality Parameters Of The Mississippi River Near St. Cloud, Mn, Stephen B. Ellingson, Alfred J. Hopwood

Journal of the Minnesota Academy of Science

ABSTRACT - Water quality parameters were monitored in the Mississippi River and three tributaries (Harris Channel, Watab Creek, and Sauk River) from July 1980 to April 1981. Results were correlated with water temperature and discharge to assess seasonal changes. Effects of tributary inflow on the river were determined. Planktonic carbon was estimated with the firefly luciferin-luciferase system which measures adenosine triphosphate extracted from viable cells. Particulate organic matter, planktonic carbon, and percentage viable carbon were correlated with temperature (p ~ 0.6) while nitrate plus nitrite was inversely correlated with temperature and discharge. Only the Sauk River affected the water quality …
