An Evaluation Of Laminated Offset Jawed Traps For Reducing Injuries To Coyotes, John M. Houben, Merrilee Holland, Sherman W. Jack, Carolyn R. Boyle Dec 1993

An Evaluation Of Laminated Offset Jawed Traps For Reducing Injuries To Coyotes, John M. Houben, Merrilee Holland, Sherman W. Jack, Carolyn R. Boyle

Great Plains Wildlife Damage Control Workshop Proceedings

Increasing public concern about injuries caused by foothold traps has resulted in a considerable amount of research for more humane traps. Much of this research effort has focused on evaluating the Victor No. 3 Soft-Catch trap manufactured by Woodstream Corporation, Lititz, Pennsylvania (Linhart and Dasch 1992). Research has concentrated on two major areas: (1) efficiency and selectivity of different trap types and modifications used for capturing coyotes (Canis latrans) and (2) reducing animal injuries associated with trapping (Phillips and Mullis 1991). The Soft-Catch trap has been shown to reduce foot injury sustained by most captured furbearers (Tullar 1984, Olsen et …

Test Results Of A New Snake Repellent, Rex E. Marsh Dec 1993

Test Results Of A New Snake Repellent, Rex E. Marsh

Great Plains Wildlife Damage Control Workshop Proceedings

When a new snake repellent came on the market, Dr. Ts Snake-A-Way, consisting of 7% naphthalene and 28% sulfur, we began to receive some inquiries as to its efficacy. To satisfy our own interest and that of potential consumers, we established a test protocol. The test room was 10 x 20 ft. in size with a 10 ft. ceiling and the floor was smooth concrete. As per label directions, a 12 inch wide band of the granular repellent was sprinkled on the floor in a center strip both lengthwise and crosswise in the room which divided the room into 4 …

A Prairie Dog Abatement Program In San Juan County, Utah, Terry A. Messmer, Jim Keyes, Roy Mcdonald

Great Plains Wildlife Damage Control Workshop Proceedings

Four species of prairie dogs are native to the plains and plateaus of the western United States. The most abundant and widely distributed of these is the blacktailed prairie dog, (Cynomys ludovicianus). This species has been a frequent topic of discussion at previous Great Plains Wildlife Damage Control workshops.


Future Extension Programs On Wildlife Damage Management, James E. Miller Dec 1993

Future Extension Programs On Wildlife Damage Management, James E. Miller

Great Plains Wildlife Damage Control Workshop Proceedings

Extension educational programs, in cooperation with other federal and state organizations, significantly contribute to the present status of wildlife damage management as understood by natural resources professionals and the interested public. Although Extension Service, USDA provides national leadership and coordination of programs, most of the effective programs originate at the state and local level Cooperative Extension Service, regardless of the subject matter. This is particularly true in the area of wildlife damage management. For example, a recent compilation of Extension publications and videotapes on wildlife damage management identifies well over 100 titles available throughout the CES System (Ruff, Craven and …


Wildlife Damge And The Iowa Farmer. The Influence Of Perspective, James L. Pease Ph.D. Dec 1993

Wildlife Damge And The Iowa Farmer. The Influence Of Perspective, James L. Pease Ph.D.

Great Plains Wildlife Damage Control Workshop Proceedings

Over 90% of Iowa's land base is privately owned and managed for agriculture. Less than 2% is publicly-owned and managed specifically for wildlife. Thus, virtually all of Iowa's 36 million acres (14.8 million hectares) has been altered. Some 70% of the forests have been lost, over 95% of the wetlands drained, and over 99.9% of the native prairies have been converted to agricultural, transportation, or other human uses. Such extensive alteration of habitats encourages the wildlife species that are ecological generalists to flourish. These species are also those that are most likely to come into conflict with humans, competing with …

The Impact Of European Community's Humane Trapping Resolution On U.S. Wildlife Damage Control Program, Mahadev Bhat, Robert Gotie, Luther Keller Dec 1993

The Impact Of European Community's Humane Trapping Resolution On U.S. Wildlife Damage Control Program, Mahadev Bhat, Robert Gotie, Luther Keller

Great Plains Wildlife Damage Control Workshop Proceedings

This paper discusses the implications that The European Economic Community's recent Wild Fur Regulation (WFR) might have on the U.S. wildlife damage control program. Beginning Jan. 1, 1995, the regulation will ban fur imports originating from countries which fail to (1) stop foothold trapping, and (2) adopt international humane trapping standards. Countries which pledge to adopt humane trapping standards will be granted a one-year extension to comply with the WFR. Because the European community is an important market for American furs, the regulation will affect the trapping of many American fur-bearing species, including raccoon, beaver, bobcat, muskrat, coyote, otter, badger, …


Urban Nuisance Wildlife Control In Kentucky, Thomas G. Barnes Dec 1993

Urban Nuisance Wildlife Control In Kentucky, Thomas G. Barnes

Great Plains Wildlife Damage Control Workshop Proceedings

A variety of factors including increased urbanization, decreased funding for governmental animal damage programs, and increases in some urban wildlife populations have resulted in a greater demand for urban nuisance wildlife control. Historically, this demand was met by Cooperative Extension Service (San Julian 1987), state fish and wildlife agency, or USDA-APHIS-ADC employees (Bollengier 1987). These agencies provided educational materials, consultations, and/or physically removed animals. Recently, there is an increased demand for physical animal removal evidenced by increasing numbers of private pest control operators (PCO) specializing as urban nuisance wildlife control operators (NWCO).

Livestock Protection Collars In The United States, 1988-19931, Guy Connolly

Great Plains Wildlife Damage Control Workshop Proceedings

The livestock protection collar (LP Collar) i: one of the few technical innovations: developed over the past 20 years fog managing coyote depredation on livestock Invented by Roy McBride in 1970, the LF Collar was researched at length by the Denver Wildlife Research Center (DWRC; and several cooperators before being approved for use with Compound 1080 by the U. S. Environmental Protection Agency (EPA) in 1985 (Burns et al. 1988, 1991; Connolly et al. 1978; Connolly 1980, 1985, 1990; Connolly and Burns 1990; Littauer 1984; Scrivner 1983; Scrivner and Wade 1986; TAMU 1983).


Endangered Species And Pesticides: The Kansas Program, Sue Ann Funk Dec 1993

Endangered Species And Pesticides: The Kansas Program, Sue Ann Funk

Great Plains Wildlife Damage Control Workshop Proceedings

The U.S. Environmental Protection Agency (EPA), because of its responsibility for registering pesticides for use in the U.S., is subject to the restrictions of federal Endangered Species Law. Before a pesticide can be registered, and subsequently marketed, EPA must guarantee that specific pesticides will not place an endangered species in peril. The Division of Plant Health of the Kansas State Board of Agriculture has received a grant from EPA to enforce the protection of listed species from pesticide exposure in Kansas.


How To Involve Local Communities In Wildlife Damage Control Decision-Malting, Scott R. Craven Dec 1993

How To Involve Local Communities In Wildlife Damage Control Decision-Malting, Scott R. Craven

Great Plains Wildlife Damage Control Workshop Proceedings

In most cases the impetus for wildlife damage control (ADC) comes from the individual or group victimized by the problem, i.e., the farmers losing crops to migrating waterfowl or the homeowners frustrated with the loss of valuable ornamental plants to marauding deer. These "victims" or "stakeholders" are clearly best positioned to describe the nature and extent of the problem, how they feel about it, and to comment on what action could/should be taken to reduce or end the problem.


Status Of Selected Fishes In The Missouri River In Nebraska With Recommendations For Their Recovery, Larry W. Hesse, Gerald E. Mestl, John W. Robinson Dec 1993

Status Of Selected Fishes In The Missouri River In Nebraska With Recommendations For Their Recovery, Larry W. Hesse, Gerald E. Mestl, John W. Robinson

Nebraska Game and Parks Commission: Staff Research Publications

Population density of five species of chubs and two species of minnows in the Missouri River in Nebraska has been reduced by as much as 95% since 1971. Burbot have been nearly extirpated, sauger have been greatly reduced, and blue catfish are rare. Reasons for the decline of these species include removal of snags from the river; cessation of organic matter and sediment transport because of the construction of large dams on the mainstem and tributaries; cutoff of floodplain connection through channelization, degradation, and the cessation of flooding; alteration of the natural hydrograph to meet the need for commercial navigation; …

Degradation Kinetics Of Aromatic Organic Solutes Introduced Into A Heterogeneous Aquifer, Wg Macintyre, M Boggs, Cp Antworth, Tb Stauffer

VIMS Articles

Degradation rates of benzene, p-xylene, naphthalene, and o-dichlorobenzene have been measured in a heterogeneous, unconfined aquifer during a pulse injection experiment at Columbus Air Force Base, Columbus, Mississippi. Dissolved oxygen in the pulse plume maintained aerobic conditions. Degradation kinetics calculated from the complete field data set were approximately first order with the following rate constants: benzene, 0.0070 d-1; p-xylene, 0.0107 d-1; naphthalene, 0.0064 d-1; and o-dichlorobenzene, 0.0046 d-1. Reaction rates were also calculated from a near-field subset of the data using a model based on the hydrologic characteristics of the aquifer. Shapes of the degradation rate curves were consistent with …

There are several dairy farms and milk processing plants in U.A.E. which contribute to the problem of industrial wastewater discharges in the country. This study emphasized the waste management aspects of dairy farms and examined the wastewater characteristics, wastewater treatment and effluent reuse in Al-Rawabi Dairy Plant in Dubai as a case study.

An extensive sampling and analysis program was conducted over a period of one year to determine wastewater characteristics at Al-Rawabi Dairy Plant. It has been found that the wastewater COD, BOD, Solids, Nitrogen and Phosphorus content is relatively high but daily variations in pollution loads were not …


Upgrading Biological Treatment Of Wastewater At Dubai’S Plant By A Fixed-Film System, Rashid Ahmed Bin-Fahad Dec 1993

Upgrading Biological Treatment Of Wastewater At Dubai’S Plant By A Fixed-Film System, Rashid Ahmed Bin-Fahad

Theses

The wastewater treatment plant in Dubai, with a design capacity of 130,000 m3/d, receives primarily domestic wastewater and employs primary, secondary and tertiary stages of treatment to produce an effluent suitable for reuse in irrigation. Performance of the plant is influenced to a great extent by the success of the secondary aerobic biological treatment stage. This stage comprises the high-rate activated sludge system for removal of carbonaceous organics followed by the biofilter system for removal of nitrogenous material by nitrification. Operational problems have often been experienced at this plant because of increasing sludge solids production and sludge rising …

Canyonlands National Park And Orange Cliffs Unit Of Glen Canyon National Recreation Area, Environmental Assessment For Backcountry Management Plan, Canyonlands National Park, Glen Canyon National Recreation Area

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

Whether on foot. bicycle. horseback. or in vehicles, most visitors come to Canyonlands National

Park (Canyonlands) to experience solitude or to "get away from people." Yet visitation to

Canyonlands has risen exponentially over the past five years (Figures I and 2). Visitation is expected to continue to rise. As a function of this increase in number of visitors, adverse impacts to Canyonlands' resources have increased and the visitors' ability to find solitude has decreased. Since the mandate of the National Park Service (NPS) is to balance visitor access

to the parks with preservation and protection of natural and cultural resources, …


Diversity: How To Lie With Biodiversity, Gordon H. Rodda Dec 1993

Diversity: How To Lie With Biodiversity, Gordon H. Rodda

United States Department of Agriculture Wildlife Services: Staff Publications

Biodiversity is the bandwagon of the moment. Unfortunately, the concept is sufficiently complex that almost any population biology study, with almost any conclusion, can be framed as an effort to measure or conserve biodiversity. Based on what 1 have seen in the literature and heard at recent scientific meetings, here is a primer on some of the more popular ways to bend biodiversity data.

Suppose you wish to claim that a species is disappearing. With the explanation that time and funding were limited, you might present population trajectories based on as few as two estimates of abundance. Perhaps the final …

Air Pollution Transport Modeling, David M. Paal Dec 1993

Air Pollution Transport Modeling, David M. Paal

Theses and Dissertations

This research effort addresses modeling of the transportation of air pollution in the atmosphere and the numerical analysis of the partial differential equations used in such modeling. Three Gaussian models are examined and compared using example problems. Several finite difference schemes are developed to solve the partial differential equations used in air pollution transport modeling. This study examines three Gaussian models SCREEN, AFTOX, and the program GAUSPLUM. The model GAUSPLUM is developed in this study and uses the Ada programming language and the analytic solution to the advection- diffusion equation. Numerical analysis of the partial differential equations PDE used in …

Catchment Management Report Prepared For The Dalwallinu Pithara Land Conservation District, Jenny Borger

Agriculture reports

The Pithara-Dalwallinu Land Conservation District was initiated in 1985. Over the past seven years the committee has carried out various trials, demonstrations and field days. It was decided in 1989 to go along the road of whole catchment planning utilising the Geographic Information System (GIS). It now gives me great pleasure to see the information collected over the last two years, presented as a workable document. I hope now that many farmers within the LCD will be able to use this report to aid in planning and future development of their most valued asset The Land. The Catchment Report is …
