Vegetation Analysis: A Graphical Analysis Of Plant Succession In Desert Communities Affected By Fire, Jeff Lantow

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Mojave Desert is affected by fire every year. With each fire comes the removal of old growth and, in its place, new growth – consisting primarily of those species which thrive in disturbed areas. The focus of my research is to look at plant communities that have been disturbed by fire, and examine the successional pathway of these disturbed environments. The seven environments I analyzed were burned within the last twenty years and are found in the Coleogyne ramosissima ecotone throughout the Spring Mountain range near Las Vegas, Nevada. The data was collected with randomly chosen circle plots in …

Lead Shot Concentration In Soil At The Overton Wildlife Management Area, Nevada, George R. Bertoty

UNLV Theses, Dissertations, Professional Papers, and Capstones

During the spring of 1998, soil samples were collected from two areas at the Overton Wildlife Management Area (OWMA), located in the Moapa Valley of Clark County, Nevada. Lead shot has been banned for the hunting of waterfowl since 1986 but is still legal for upland game hunting. Both types of hunting occur at OWMA. One area sampled is a cultivated field and serves primarily as a dove hunting area. The other area is primarily a waterfowl hunting area and is flooded during the waterfowl-hunting season. Lead shot was recovered from 83% of the samples from the dove hunting area, …

A Strategic Analysis Of The Rocky Flats Cleanup, Patrick Mccann

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Rocky Flats Environmental Technology Site is located in Golden, Colorado. It is situated on 384 acres in a 6,550-acre natural preserve. Rocky Flats ended its original mission in 1989, after raids on the site by both the FBI and the EPA for illegal dumping and other environmental violations. Since then the site has been scheduled for cleanup. This thesis will provide background information on the site and on the company hired to perform the cleanup. It also provides an evaluation of some key policies regarding the cleanup procedures. Since the end of the cold war, the production of nuclear …

The Price Of Clean Air: A Consideration Of Market Based Emissions Trading, Mark W. Miller

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traditional regulatory approaches for environmental protection do not consider

the costs and benefits of the standards they impose. Further, imposing strict performance

standards on firms with heterogeneous control costs leads to an inefficient allocation of resources devoted to pollution control. This paper explores the use of emission allowance trading as a way to improve economic efficiency within the context of environmental protection. PM10 air pollution from sources within the Las Vegas Valley is used as the case study.

This paper found that an emission trading

program in this particular case study would not live up to the theoretical expectations. Although, …
