Prairie Dog Control: A Computer Model For Prairie Dog Management On Rangelands, Mike K. Cox, Scott E. Hygnstrom

Great Plains Wildlife Damage Control Workshop Proceedings

Black-tailed prairie dogs (Cynomys ludovicianus) share rangeland with other wildlife and livestock. The use of public grasslands and private pastures continues to intensify because of multiple-use and economic concerns. Countless prairie dog control programs have been conducted to reduce potential conflicts between livestock grazing and black-tailed prairie dogs. There are many questions regarding prairie dog control on rangeland, such as how prairie dog complexes effect livestock grazing, how quickly or slowly complexes expand and contract, and the cost-effectiveness of prairie dog control when associated with livestock grazing. An interactive computer model was written in BASIC for IBM-compatible personal computers to …

Landscape Plants, Forest Trees, And Crops Most Resistant To Mammal Damage: An Overview, Rex E. Marsh

Great Plains Wildlife Damage Control Workshop Proceedings

To capitalize on mammal-resistant plants, several approaches may be taken. The most common is to select crops not highly prone to mammal damage (i.e., resistant crops). If a generally susceptible crop is to be grown, the more resistant varieties or cultivars of that crop can be selected, if known. An approach that has not received the attention it warrants is the selection of parent stock with resistant characteristics and the selective breeding of useful species to develop strains, hybrids, or cultivars with improved mammal resistance. For several reasons, this latter approach shows the most promise for forest tree species. It …

Vertebrate Impacts On Oak Regeneration In California: A Review Of Management Options, Robert H. Schmidt, Robert M. Timm

Great Plains Wildlife Damage Control Workshop Proceedings

Hardwoods occupy about 25% of the total forest area in California (Bolsinger 1988). Predominant among the hardwoods are oaks (Table 1). Over the past 10 years, concerns have been raised about the ability of some oak woodland stands to replace themselves. These concerns have focused on 2 distinct management dilemmas. The first involves the gradual loss of oak woodland acreage due to human activities. These activities often involve some type of conversion, such as the clearing of trees for rangeland improvement, production agriculture, or residential development (Schmidt and Tietje 1987). The rapid increase in California's population means more pressure on …

Incidence Of Urban Vertebrate Pest Problems In The Greater Omaha, Nebraska Area, Dennis M. Ferraro

Great Plains Wildlife Damage Control Workshop Proceedings

Human interactions with wildlife and vertebrate pest species are a common occurrence in metropolitan areas. There are a number of common encounters, however, each urbanized location has unique prob-lems. Additionally, within each metropolitan area there is a gradient of encounters based on localized habitats, urban intensity, and length of urbanization. Information obtained from public inquiries directed to the Uni-versity of Nebraska-Extension in Douglas County, Nebraska were used to compile a review of these interactions in the Omaha, Nebraska metropolitan area (Table 1). Data were collected from May to December 1990. Approximately 25% of all "pest" inquiries concerned vertebrate species. In …

Adc Program Compliance With The National Environmental Policy Act, Guy E. Connolly

Great Plains Wildlife Damage Control Workshop Proceedings

The U.S. Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS) conducts a national, cooperative Animal Damage Control (ADC) program for the protection of American agriculture and other resources from wildlife damage. Like all Federal governmental activities, APHIS-ADC must comply with the National Environmental Policy Act (NEPA) of 1969, as amended. This law directs Federal agencies to analyze the environmental impacts of major Federal actions, incorporate environmental considerations into decision making, and generally to mitigate adverse environmental impacts due to governmental activities. NEPA also established the Council on Environmental Quality (CEQ) to promulgate regulations for implementing the procedural …

Effectiveness Of Nylon Lines For Deterring Rock Doves From Landing On Ledges, William F. Andelt, Kenneth P. Burnham

Great Plains Wildlife Damage Control Workshop Proceedings

Abstract: The effectiveness of 74-kg, white, twisted nylon twine was evaluated for deterring rock doves (Columba livia) from landing on ledges at Colorado State University's Hughes Stadium in a controlled experiment during 1990. One, 2, and 3 lines were stretched 8 cm in front and 12 cm above (1 line), 8 and 18 cm above (2 lines), and 5, 12, and 18 cm above (3 lines) the ledges. The proportion of successful landings to attempted landings was reduced from 0.99 (0 lines) to 0.23 (1 line), 0.13 (2 lines), and 0.10 (3 lines). The number of pretreatment landings per ledge …

Investigation Of The Relationship Of Earthquakes And Underground Waste Disposal In The El Dorado Area, Arkansas, Randel Cox, Roy B. Vanarsdale

Arkansas Water Resources Center Technical Reports

From December, 1983 to September, 1989 twelve small earthquakes were recorded for the El Dorado, Arkansas area. Magnitudes of these earthquakes were well below damaging levels. Prior to this time no seismicity was reported in the area, suggesting that the earthquakes were not naturally occurring and may have been the result of human activity. El Dorado is located at the margin of a region of underground waste brine disposal and along a major fault zone. Elevated pore pressures resulting from brine disposal may have reduced the normal (locking) stresses across fault surfaces and triggered fault movement. Two injection wells (Great …

Plate Tectonics, Space, Geologic Time, And The Great Plains: A Primer For Non-Geologists, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

For most Americans, "The Great Plains" evokes images of grasslands, dust storms, prairie fires, Native Americans on horseback, cowboys and wheat lands, and perhaps flat valleys crossed by braided rivers carrying a heavy load of sand and gravel, extremes of weather, and a climate typified by an alternation of droughts and wetter periods. Geologists picture such general images, too, but they also see radical changes in the landscape over periods expressed in millions rather than hundreds of years. Geologically speaking, human activities on the Great Plains are too recent to have much of a place in the broad geologic history …

Late Paleozoic Cyclic Sedimentation In Southeastern Nebraska: A Field Guide, Roger K. Pabian, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

People studying and collecting sedimentary rocks, minerals, and fossils in eastern Nebraska often find that locating rock exposures can be difficult. Most of the rolling hills in the eastern sixth of the state are underlain by thick, interlayered, glacial deposits, loess (windblown silt), and alluvium (stream-deposited sediments) of very young geologic age. These sediments cover the bedrock in most of that area. Natural exposures and human excavations of bedrock are mostly confined to the sides and floors of stream valleys. However, in the southeasternmost counties of the state, the younger sediment cover is commonly thin or absent. Pawnee and Richardson …

The Effects Of Urbanization On A Portion Of The Portage Creek Watershed: A Case Study On Surface Water And Groundwater Quality, Susan E. Rezek

Masters Theses

The surface water and groundwater quality in the study area of the Portage Creek watershed was analyzed to determine the possible effects of urbanization. Dry weather and wet weather surface water and groundwater samples were collected from June 1986 to November 1986 at selected stations in the watershed.

Water samples were analyzed for 26 inorganic and organic parameters. Most concentrations were below analytic method detection limits. The analytical data indicate that sodium and chloride are the principal contaminants resulting from urbanization. The probable source of the contamination is deicing salt applied to the City of Portage, Michigan streets.

Overall, the …

Bird Hazing And Frightening Methods And Techniques (With Emphasis On Containment Ponds), Rex E. Marsh, William A. Erickson, Terrell P. Salmon

Other Publications in Wildlife Management

Our primary purpose in preparing this overview of bird hazing or frightening methods and techniques is to provide the owners and operators of agricultural evaporation ponds with all possible information on hazing to minimize bird use of the ponds and reduce their exposure to possible contamination from accumulated substances, such as selenium.

While our main objective was to assist pond managers, our coverage of bird hazing is intentionally broad enough to be highly relevant to protect many agricultural crops and some aquaculture facilities from bird depredations, and to reduce bird numbers at airports where the potential for bird-aircraft strikes is …

Lines To Selectively Repel House Sparrows From Backyard Feeders, Kimberly K. Kessler, Ron J. Johnson, Kent M. Eskridge

Great Plains Wildlife Damage Control Workshop Proceedings

House sparrow {Passer domesti-cus) flocks are often disliked at backyard feeding stations because they use space and food intended for other species. Monofila-ment lines, spaced 30 or 60 cm apart, have been shown to repel house sparrows from certain feeders, but responses of many back-yard bird species to lines are unknown. Three experiments were conducted at 2 sites during winter and repeated in spring using feeders with and without lines. Four pole-mounted feeders were used at each site, with an 80-cm-diameter tray on the ground below each feeder. Two feeders at each site were controls (C) without lines and 2 …

Perceptions About Crop Yields And Losses To White-Tailed Deer On Farms Surrounding Gettysburg National Military Park, Gary M. Vecellio, Gerald L. Storm, Richard H. Yahner

Eastern Wildlife Damage Control Conference: 5th (1991)

Our objectives were to determine the perceptions of farm operators concerning crop yields, and effects of white-tailed deer (Odocoileus virginianus) on crop lands surrounding Gettysburg Park. The survey consisted of 4 multiple-choice and 5 fill-in questions. Questions were developed to gauge land area planted and harvested by crop type, relative severity of impacts to crops by 8 wildlife species, and amount of crop production lost to deer. Questions were also included to quantify perceptions on the 5-year trend in deer numbers, respondent's wishes for future deer numbers, and the number and type of people permitted to hunt deer …

Use Of Livestock Protection Collars To Protect Sheep And Goats, Murray T. Walton

Eastern Wildlife Damage Control Conference: 5th (1991)

The sodium monofluoroacetate (Compound 1080) Livestock Protection Collar is selective for individual predators attacking the throat of sheep or goats and is especially useful in taking coyotes (Canis latrans). However, fears of secondary and nontarget poisonings have resulted in restrictions on their use. They are registered for use in the United States only to kill coyotes. To satisfy U.S. Environmental Protection Agency requirements, the Texas Department of Agriculture provides training and testing for certifying collar applicators, and has monitored collar use from 1988 through 1990. During this period, 59 licensed applicators, 6 collar pools, and the Texas Animal …

Fisheries Research Report No 91 - A Synopsis Of The Biology And The Exploitation Of The Australasian Pilchard, Sardinops Neopilchardus (Steindachner) Part Ii: History Of Stock Assessment And Exploitation, W. J. Fletcher

Fisheries Research Reports

This report summarises the studies which have provided information on the population characteristics and exploitation of the pilchard, Sardinops neopilchardus in Australia and New Zealand. This review was undertaken to determine whether existing data could be used to assess the status of Western Australian or other stocks or, alternatively, what additional information was required.

The mean size of pilchards caught varies among locations but, in general, fish are between 140 and 160 mm LCF, corresponding to ages 2 - 5 years. The length-weight relationship also varies between locations

Attempts to initiate pilchard fisheries have been hampered by the lack of …

Minimizing Deer Damage To Forest Vegetation Through Aggressive Deer Population Management, Raymond J. Winchcombe

Eastern Wildlife Damage Control Conference: 5th (1991)

Controlled hunts were used annually between 1976-90 on the Mary Flagler Cary Arboretum in southeastern New York to control deer (Odocoileus virginianus) population expansion and prevent over-browsing of forested and landscaped areas. The primary objective of the hunts was to remove sufficient numbers of adult female deer each year to stabilize herd growth and minimize browsing pressure. Hunters had to register early, attend a preseason meeting, pass a shooting proficiency test, apply for a deer management permit, and pay a fee. Spring browse-use surveys, using several tree species as an index to browsing pressure, showed low use through …

Bear Damage To Agriculture In Wisconsin, Laine R. Stowell, Robert C. Willging

Eastern Wildlife Damage Control Conference: 5th (1991)

Black bear (Ursus americanus) are common in northern Wisconsin. The Wisconsin Department of Natural Resources (WDNR) has established a population goal of 6,000 bears across 46,361 km2 of bear range. Bear damage to agriculture occurred for over 50 years, and various strategies have been used to address these problems. Bear damage to agricultural c and livestock became eligible for reimbursement by the state in 1939. The legislature terminated this program in 1980 in fate of a new program that placed greater emphasis on damage prevention than on compensation. Since 1984, WDNR has bear damage primarily through abatement practices …
