Controlling Raccoon Damage In Urban Areas, David G. Riley

Great Plains Wildlife Damage Control Workshop Proceedings

Raccoons have become a serious problem in many urban and suburban areas. Damage to homes and buildings as well as the spread of diseases to pets are constant problems when high raccoon populations occur. Various control methods can be implemented with positive results.

Planning For Animal Damage Control Programs Within The Animal And Plant Health Inspection Service, Philip S. Gipson, Gary P. Combs

Great Plains Wildlife Damage Control Workshop Proceedings

The Animal Damage Control Unit (ADC) and the 10 other units of the Animal and Plant Health Inspection Service (APHIS) have undergone major reorganization. Emphasis is placed on planning and risk analysis. Four levels of planning have been identified: (1) strategic planning for the Agency, (2) strategic planning for each of the 11 units, (3) program design and risk analysis, and (4) operational planning.

Seasonal Effects On Control Methods For The Great-Tailed Grackle, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores, John Hobbs, Joe Palacios

Great Plains Wildlife Damage Control Workshop Proceedings

Efficiency of methods used to control damage to citrus fruit by great-tailed grackles was found to vary considerably from season to season. From April - July, the birds congregated in small breeding colonies where they were susceptible to baiting and poisoning. From August - October, the birds could be baited in to and poisoned at watering sites. Intensive shooting and use of pyrotechnics were also used successfully at this time of year to control damage at groves with high grackle concentrations. From late October - March, birds moved over wide areas each day, and were easily frightened from groves by …

An Assessment Of The Urban Wildlife Problem, William D. Fitzwater

Great Plains Wildlife Damage Control Workshop Proceedings

Basic urban wildlife problems include: proper identification of species, shift from agrarian to urban society, different interpretations of humaneness, compassion for individual rather than a population as a whole, and public ignorance of urban pest management. Positive values are esthetics and environmental education opportunities. Negative values are disease transmission, life/injury-threatening situations, damage to buildings/other property, water structures/quality, petty annoyances, and indirect economics.

Urban Nuisance Wildlife Problems In Arizona, Rebecca L. Wright, Leonard L. Ordway

Great Plains Wildlife Damage Control Workshop Proceedings

Arizona has experienced an increase in urbanization of wildlife habitat, which has led to an urban nuisance wildlife problem. The Arizona Game and Fish Department is working to lessen the problem through public education, information packets and use of private pest control companies to remove wildlife for a fee.

Management Problems Encountered With Livestock Guarding Dogs On The University Of California, Hopland Field Station, Robert M. Timm, Robert H. Schmidtz

Great Plains Wildlife Damage Control Workshop Proceedings

Guard dogs are being promoted and utilized as effective predator damage control tools under a variety of livestock management conditions. We report our experience over 1 1/2 years with 5 dogs, primarily Anatolian shepherd and Akbash dog breeds. We discuss a number of behavioral and management problems we have encountered, some of which have not previously been reported in the literature. These include chasing vehicles and wildlife, predation on deer (Odocoileus hemionus columbianus), and incompatibility of dogs with other predator damage control methods.

Seasonal Variation In Habitat Use By Great-Tailed Grackles In The Lower Rio Grande Valley, John H. Rappole, Arlo H. Kane, Rafael H. Flores, Alan R. Tipton, Nancy Koerth

Great Plains Wildlife Damage Control Workshop Proceedings

Habitat use by great-tailed grackles was measured by performing weekly censuses of birds in 6 different habitat types: chaparral, citrus groves, feed lots, pastures, residential areas, and agricultural fields. We found that use of chaparral, citrus, and residential sites was low during the winter months, increased sharply with commencement of the nesting season in April, and declined again by October. Use of agricultural fields and pasture was irregular. Feed lot use was low during the summer, but high from October - April with October and March migration peaks. An overall sex ratio of 1.3 females/male was observed with skews from …

Fisheries Management Paper No.23 - Management Of The South-West Inshore Trawl Fishery., N. Moore

Fisheries Management Papers

This report outlines the management plan for the south west inshore trawl fishery which already operates in coastal waters less than 200 metres deep between Guilderton and Cape Leeuwin.

This management plan takes into account these important concerns and has specifically set aside a strip of coastal area from Cape Bouvard to Cape Leeuwin for recreational usage and for protection of the benthic community, and closed the management zone north of Burns Beach to trawling.

Biochemical And Morphological Characteristics In Maturing Achenes From Purple-Hulled And Oilseed Sunflower Cultivars, Roger W. Bullard, Paul P. Woronecki, Richard A. Dolbeer, J. Russell Mason

United States Department of Agriculture Wildlife Services: Staff Publications

The blackbird feeding preference for sunflower oilseed variety Jacques Discovery (JD) over purple-hulled Neagra de Cluj (NdC) has been attributed to anthocyanin. To test this hypothesis, we compared biochemical and morphological properties in the achene over the maturation period. Comparisons included total phenols, anthocyanin, tannin, fat/oil, protein, nonstructural sugars, and phytomelanin contents, as well as mass properties and moisture content. Only three differences were observed: (1) Hull mass was significantly higher for NdC than JD. (2) Anthocyanins were synthesized by NdC only. (3) JD was higher in oil content. Each of these factors may play a role in reduced preferences …

The Use Of Banding Recovery Data To Estimate Dispersal Rates And Gene Flow In Avian Species: Case Studies In The Red-Winged Blackbird And Common Grackle , William S. Moore, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Dispersal resulting in gene flow strongly affects the evolution of genetic structure in populations. This report describes statistical estimators of dispersal parameters based on USFWS banding recovery records. Finite-area studies of avian species yield estimates of root-mean-square (RMS) dispersal along a transect of about 1 km per generation. In contrast, estimates of RMS dispersal for the Red-winged Blackbird (Agelaiusp hoeniceus) and Common Grackle (Ouiscalus auiscula), based on USFWS banding recovery records, are 94.6 and 111.4 km per generation, respectively. Distributions for both species are extremely leptokurtic, and confidence intervals based on jackknife statistics are large because the estimators are sensitive …

An Analysis Of The Factors Influencing Eutrophication Within The China Lake Watershed, Student Collective Organized Against Lake Eutrophication, Colby College, Problems In Environmental Science Course (Biology 493), Colby College

Colby College Watershed Study: China Lake (2005, 1989)

Lake eutrophication is the natural process of aging in the lake body with establishment and multiplication of organism over time. The sediment and decaying matter accumulate, gradually filling in the lake basin, transforming the lake from a deep lake to dry land. This process affects the physical make-up of the lake as well as the ecological and biological composition. Eutrophication usually takes thousands of years. However, human interference has greatly accelerated the process by increasing rates of sedimentation and phosphorus loading. China lake has undergone accelerated eutrophication in recent years causing a growing concern for water quality. Algal populations, stimulated …

Assessment Of Squirrel-Caused Power Outages, J. Chris Hamilton, Ron J. Johnson, Ronald M. Case, Michael W. Riley

School of Natural Resources: Faculty Publications

Squirrel-caused power outages in Lincoln and Omaha, Nebraska, were evaluated by examining company power outage reports and by consulting with power company representatives. Reports showed that squirrel-caused outages at pole-mounted transformers were most prevalent during May, June, and October (48% of total) and between 1 and 4 h after sunrise (38%), patterns that coincide with squirrel dispersal or morning activity periods. In Lincoln, 1980 and 1981, squirrels caused 177 outages per year, which was 24% of all outages and 90% of animal-caused outages. Estimated minimum annual costs were $23 364 for repairs, public relations, and lost revenue while meters were …

Geology Of The Pre-Dune Strata, James B. Swinehart, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Over the last 98 million years, four general geological processes have acted to shape the ancient landscapes buried beneath the Sand Hills. Three of these affected the area directly, either depositing sediments on the land surface or eroding it, while a fourth took place west of Nebraska, but affected the region nonetheless.

Shells of clams, oysters, and numerous other kinds of creatures similar to forms that live today in the seas are preserved as fossils in the chalks, limestones, and shales that form the oldest rocks beneath the Sand Hills that will be described. These deposits indicate to geologists that …

A Site-Specific Need Assessment For Ocean Incineration At The North Atlantic Incineration Site (Nais), Lynne H. Macdonald

Marine Affairs Theses and Major Papers

This thesis examines the problems of hazardous wastes in the United States-and the problems their disposal present, in particular. Ocean incineration, one of the very few methods available to destroy many highly toxic wastes, is presented as a viable, necessary means to destroy liquid organochlorine wastes. Next, the international and federal regulations governing ocean incineration and the current status of ocean incineration in the United States are reviewed. A site-specific assessment for determining the need for ocean incineration is developed as an alternative to the two currently contended approaches (nationwide versus permit-by-permit need assessments). This site-specific need assessment evaluates the …

Formulation Of A Management Scheme For The Swordfish Fishery Of The Eastern Caribbean, Harold F. Upton

Marine Affairs Theses and Major Papers

During the 1983 season, two U.S. longline vessels initiated the first attempts at the commercial exploitation of swordfish in the Eastern Caribbean. In 1986, the number of U.S. vessels participating in the fishery surpassed 40 with landings of nearly two million pounds per season. The sudden influx of participants and technology to the region has resulted in a variety of user conflicts and associated policy issues. Major areas of concern involve the conservation of a heavily exploited resource and the distribution of benefits which accrue from resource exploitation among the resource-adjacent island states and U.S. fishing operations. This study examines …

Antarctic Peninsula Mysticete Whales: Conservation And Research, Gregory Schofield Stone

Marine Affairs Theses and Major Papers

This paper reports original research from two recent studies in the Antarctic Peninsula area, reviews past sighting information and policies affecting mysticete whales, and recommends future research. Due to poor management by the International Whaling Commission, mysticete whales are among the most severely depleted species groups in the Antarctic. The combined total Antarctic harvest from 1920 to 19867 for blue Balaenoptera musculus, fin B. physalus, sei B. borealis, minke B. acutorostrata and humpback Megaptera novaeangliae whales was over one million animals. The effect of this hunting pressure is the dominant factor determing the present status of Antarctic …

North Carolina Ports: A Search For Identity, Clifford S. Sharpe

Marine Affairs Theses and Major Papers

North Carolina's development in colonial times and in the early stages of statehood was greatly affected by her coastline. An abundant coastline did not translate into an abundance of good ports, in fact, difficult coastal and inland navigation hampered early commercial development. North Carolina's barrier islands and numerous inlets served as a haven for pirates in colonial days, for privateers during the Revolution, and later defied the North's blockade during the Civil War. There were several attempts by individuals to encourage maritime trade in the late nineteenth and early twentieth century. Shortly after World War II the state mobilized to …

Estimating Forage Values For Grazing National Forest Lands, United States Department Of Agriculture Economic Research Service

All U.S. Government Documents (Utah Regional Depository)

Every 5 years, the Forest Service is required to update its estimates of the value of Forest Service grazing. This report provides estimates of the maximum ability of ranchers to pay for Forest Service grazing. Abilities to pay vary greatly depending on the region of the country and assumptions about costs. Based on current cash costs, the value of Forest Service grazing is greater than the grazing fee. Based on longrun economic costs, the value of grazing is less than the grazing fee. In some regions of the United States, the longrun value of grazing is zero. These low longrun …

Erosion Potential Of Phomopsis-Resistant Lupins, D J. Carter, Paul Findlater

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

During lupin harvesting, up to 20 per cent of the grain remains on the ground. This non-harvested or pilt grain is a valuable feed for sheep during early summer because the pods, leaf and stem generally provide little nutrient in the stubnbles. In addition, the more efficient the weed control, the less valuable are the stubbles.

The disease lupinosis caused by Phomopsis leptostromiformis restricts the amount of grazing from the lupin stubbles, and hence the risk of wind-erosion of stubble paddocks.

However, the introduction of lupin varieties moderately resistant to Phomopsis and with reduced potential to cause lupinosis means that …

Wildlife Damage Management (Wdm) In The Southern Utah Adc District, United States Department Of Agriculture, Animal And Plant Health Inspection Service, Animal Damage Control

All U.S. Government Documents (Utah Regional Depository)

Across the United States, wildlife habitat has been substantially changed as human populations expand and land is used for human needs. These human uses and needs often compete with wildlife which increases the potential for conflicting human/wildlife interactions. In addition, segments of the public strive for protection for all wildlife; this protection can create localized conflicts between human and wildlife activities.

The Plight Of The ‘Forgotten’ Whales, Robert L. Brownell Jr., Katherine Ralls, William F. Perrin

United States Department of Commerce: Staff Publications

The “Save the Whales” movement, the most successful wildlife crusade in history, has greatly influenced government policies in a number of countries, including the United States. Thanks in large part to the movement’s dedicated members, the fight to save the great whales has been largely won. Yet all but ignored in this victory has been the plight of smaller cetaceans, which continues to worsen.
