The Eldorado Landfill: A Case Study, Heather A. Nash

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 1995, Boulder City bought from the federal government 167 square miles of land in the Eldorado Valley which is located approximately seven miles west of the city. Soon afterward, the current landfill in Boulder City began accepting construction waste from Las Vegas. The large dump trucks had to travel through Boulder City on route to the landfill. In doing this they passed through three school zones and residential areas. When residents began complaining about the trucks, the Boulder City City Council began investigating various ways to solve the problem. The solution they adopted was to construct a new landfill …

Acid Mine Drainage And Its Effects On Salamander Assemblages In Cumberland Plateau Streams Of The North Chickamauga Creek Watershed, Tennessee, Melissa Combs

Honors Theses

In Appalachia's coal mining regions, acid mine drainage (AMD) has contributed to the widespread degradation of stream ecosystems. Salamanders are common inhabitants of healthy headwater streams and because of their permeable skins are excellent indicators of ecosystem intergrity. Hence, we investigated the potential effects of AMD on the species richness and relative abundance of aquatic salamanders in selected stream reaches (sites) of the North Chickamauga Creek (NCC) system, Tennessee. Specimens were collected by kick-net sampling with a 500um mesh dip net and/or electroshocking at four AMD-impacted sites (pH< 5.6) and two reference sites pH> 6.2), May-July 1996. Species richness was similarly low at reference sites, 2 …

Development Of A Fluorescent Indicator For Inorganic Monochloramine, Xiaojun Dong Zou

Chemistry & Biochemistry Theses & Dissertations

Current methods used to determine combined residual chlorine cannot distinguish between inorganic monochloramine (NH₂Cl) and organic chloramines. Studies described in this thesis were carried out to develop a novel method of determining the concentration of inorganic monochloramine in aqueous solutions. Based on the observation that the reaction of 3-formyl-1-methylpyridinium chloride (3FMPCl) with NH₂Cl produces a solution which is fluorescent, experiments were conducted to characterize the reaction and optimize the experimental conditions. Using the finalized protocol, NH₂Cl measurements were made in the presence and absence of organic amines and compared with a commonly used N, …

Composting Landscape Waste From The University Of Nevada, Las Vegas, K. Jill Hammond

UNLV Theses, Dissertations, Professional Papers, and Capstones

The University of Nevada, Las Vegas is a major producer of organic waste in the Las Vegas Valley. Composting landscape wastes is one way to reduce both landfill dumping and fertilizer costs for the university. It is also an environmentally friendly means of curbing a nationwide problem: unnecessary use of landfill space. Three sites within Clark County were analyzed for the feasibility of composting: Frenchman Mountain, UNLV Campus, and Boulder City Landfill. Using cost analysis, water availability, and other factors to analyze each site, Boulder City Landfill appears to be the best place to house UNLV's composting operation. Composting in …

Evaluating Cable Resistance To Pocket Gopher Damage - A Review, Craig A. Ramey, Geraldine R. Mccann

Great Plains Wildlife Damage Control Workshop Proceedings

The National Wildlife Research Center, formerly known as the Denver Wildlife Research Center (DWRC), collaborated with telecommunications and energy industries to evaluate cable resistance to pocket gopher damage for 29 years (1966 to 1995). Recently, DWRC's evaluation process was transferred to private contract laboratories. This review summarizes the chronology of key investigations and procedures that were used and first published on cable resistance to rodent damage. The longstanding cooperative goal of both DWRC scientists and industry engineers was the development of rodent-proof, buried cables and ducts. Even though most data collected were proprietary, extensive laboratory testing at DWRC provided data …

Control Of Nuisance Birds By Fogging With Rejex-It® Tp-40, Peter F. Vogt

Great Plains Wildlife Damage Control Workshop Proceedings

Many bird problems are caused by birds congregating, roosting, loafing, and nesting rather than by the birds’ feeding activities. No matter what their activity, eventually birds will need to be driven off, preferably in a so-called “friendly” way without harming the birds or other animals. Unlike other avian aversion methods, fogging of ReJeX-iT® TP-40 relies on the exposure of the target birds to the aerosol rather than relying on birds eating treated food. Best results are achieved when birds congregate in the early morning or early evening when they settle down. After several exposures the birds generally leave the area …

Impact Of Preventive Aerial Coyote Hunting On Sheep Losses To Coyote Predation, Kimberly K. Wagner, Michael R. Conover

Great Plains Wildlife Damage Control Workshop Proceedings

Coyote (Canis latrans) predation is a serious problem for livestock producers in the Western U.S. In Utah, Idaho, and Wyoming, 34% of all producer-reported sheep and lamb losses were to coyote predation, amounting to $4.8 million in losses during 1995. Although preventive aerial hunting is commonly used by agriculture agencies in the Intermountain West to reduce coyote (Canis latrans) predation on sheep (Ovis aries), only limited data are available on the efficacy of the technique. We assessed the impact of winter (January - March) aerial coyote hunting on sheep losses to coyotes and the …

Development And Registration Of A Pracical Tranquilizer Trap Device (Ttd) For Foot-Hold Traps, Doris E. Zemlicka, D. Pete Sahr, Peter J. Savarie, Frederick F. Knowlton, F. Sherman Blom, Jerrold L. Belant

Great Plains Wildlife Damage Control Workshop Proceedings

Foot-hold traps can be used to selectively capture coyotes (Canis latrans) and wolves (C. lupus). However, injuries to captured animals sometimes occur when they struggle to escape. Tranquilizer trap devices (TTDs) reduce struggling and injuries but prototype TTDs were too expensive for widespread use by animal damage control (ADC) operational personnel. For this reason, the Pocatello Supply Depot (PSD) and the National Wildlife Research Center (NWRC) are investigating alternative TTD designs. A molded-rubber TTD will be available from the PSD for coyotes, and the NWRC continues to explore other cheaper TTD designs. A practical TTD …

Field Trials Of Alpha-Chloralose And Drc-1339 For Reducing Numbers Of Herring Gulls, Paul P. Woronecki, Richard A. Dolbeer, Thomas W. Seamans

Great Plains Wildlife Damage Control Workshop Proceedings

We compared the potential of Alpha-chloralose (A-C) and DRC-1339 to reduce a nesting population of herring gulls at an industrial site in Ohio in 1988. Almost all treated baits were consumed by gulls but only about one affected gull was noted for every 10 baits consumed of either chemical. A test indicated our DRC-1339 baits. containing 3.7 - 7.4 times the published LD value, were not lethal to most captive herring gulls living in fresh water. LD values of A-C and DRC-1339 need to be more precisely estimated for gull species in fresh and salt water environments.

Cooperative Wolf Depredation Management In Wisconsin, Robert C. Willging, Adrian P. Wydeven

Great Plains Wildlife Damage Control Workshop Proceedings

A depredation management plan was an important component of Federal and State recovery plans for the endangered gray wolf (Canis lupus) in Wisconsin. The Wisconsin Department of Natural Resources (WDNR) entered into a cooperative agreement with USDA-APHIS-ADC to cooperatively manage wolf depredations. Response to complaints involving wolf-dog hybrids was also part of the cooperative agreement. From 1990-1996 ADC investigated 60 wolf complaints and confirmed 10 depredations. In the same time period, WDNR paid a total of $21,376 in compensation payments for 21 incidents of wolf depredations. Wolves may be downlisted from endangered to threatened within the next five …

Wildlife-Caused Losses Of Agricultural Commodities In 1994 With Emphasis On The Great Plains, A.P. Wywialowski

Great Plains Wildlife Damage Control Workshop Proceedings

The USDA, National Agricultural Statistics Service (NASS) surveyed 16,000 agricultural producers in January 1995. Of 10,144 respondents nationwide, 58% reported wildlife-caused losses of their commodities, an increase from 55% in 1989. Based on the median value of all producers' estimates of their losses, wildlife-caused losses cost producers approximately $591 million in 1994, $130 million more than in 1989. Losses presented are based on median producer estimates which have been shown to be consistent with field-measured estimates of damage. Because the dollar value of losses are based on median estimates, extremes of reported losses do not affect these results. If all …

Relative Effectiveness Of Various Breeds Of Livestock Guarding Dogs For Reducing Predation On Domestic Sheep In Colorado, William F. Andelt, Stuart N. Hopper

Great Plains Wildlife Damage Control Workshop Proceedings

We surveyed 59 livestock producers that used multiple breeds of livestock guarding dogs to determine their ratings of the relative effectiveness of guarding dogs for deterring predation on domestic sheep in Colorado during 1995. Significantly (P < 0.05) more producers rated Akbash dogs as more effective than Great Pyrenees for deterring predation by coyotes (Canis latrans), black bears (Ursus americanus), mountain lions (Felis concolor), domestic dogs, and all predators combined. Significantly more producers also rated Akbash dogs as more effective than Komondors for deterring predation by coyotes and all predators combined. Great Pyrenees and Komondors were rated as similar in effectiveness for deterring predation. Significantly more producers rated Akbash dogs as more aggressive, …

Efficacy Of Turf Shield Repellent On Reducing Damage By Canada Geese And Mallards, Leonard Askham

Great Plains Wildlife Damage Control Workshop Proceedings

Concentrations of 1/2 to 8 gal of Bird Shield repellent were tested to assess their efficacy on Canada geese and Mallards, determine their potential longevity under natural conditions, and develop strategies to control the bird's use of turf grass areas where they had become physical, aesthetic or health problems to the resource's manager. During the first phase of the trials, each of the concentrations appeared to reduce the birds' use of the treated sites when compared with the untreated control sites. During the second phase of the trial, efficacy was more pronounced when a day use area at a state …

Food Habits Of Mountain Lions In The Trans-Pecos Region Of Texas, Rosemary A. Heinen, S. Kemble Canon

Great Plains Wildlife Damage Control Workshop Proceedings

Information regarding mountain lion (Felis concolor) food habits is relatively scarce overall, and this is particularly true in the Trans-Pecos region of Texas. Most information currently available is from Big Bend National Park where livestock are excluded and game animals are not actively managed. This study involved the analysis of 32 mountain lion stomachs collected throughout the Trans-Pecos over a 14 month period. Deer (Odocoileus spp.) and javelina (Tayassu tajacu) were the predominate prey species, each occurring in 39% of the stomachs analyzed. Domestic livestock was found in 9% of the total stomachs and non-game …

You have to ask yourself, why would you start a technical session dealing with communications. You know we are all here to learn various aspects of our trade. Why start it out with a session on communications? Well, let me give you the answer to that one. The success of every enterprise depends on public goodwill. When I first read that I thought, yes, in a free society the success of every enterprise depends on public goodwill. But then the Berlin wall came down, communism collapsed and you realize that even tyranny cannot withstand the pressure of public goodwill. So, …

Depredation On Artificial Ground Nests By Japanese Macaques: The Unspoken Exotic In Texas, Justin G. Feild, Scott E. Henke, Justin G. Mccoy

Great Plains Wildlife Damage Control Workshop Proceedings

Japanese macaques (Macaca fuscata) are old world monkeys that were introduced to Texas in 1972, and their population has since increased to over 800 individuals. Macaques are considered to be primarily vegetarian but will opportunistically forage on a variety of food items. Therefore, the objective of this study was to determine if macaques impact the nest success of bobwhite quail (Colinus virginianus). In June 1996, 20 artificial ground nests simulating those of bobwhite quail were placed randomly in areas with and without macaques. Nests were checked at 3-day intervals for 24 days and nest success was …
