Challenges For The New West: Economic Impacts Of Wilderness In Nevada's Rural Counties, Lesley Regina Argo Dec 2001

Challenges For The New West: Economic Impacts Of Wilderness In Nevada's Rural Counties, Lesley Regina Argo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Public lands designated as part of the National Wilderness Preservation System are removed from multiple-use management for protection of their natural condition. Opponents argue that "locking up" the natural resources on these lands through designation will undermine the rural economies in the west that are dependent upon extractive industries such as mining and logging. Proponents argue that the "Old West" reliance on extractive industries is declining and, in the "New West", wilderness promotes economic development in rural communities by preserving the amenity values that draw population and employment to the region. Characteristics of Nevada's economy, population and land challenge the …


The Suitability Of Reclaimed Agricultural Lands Along The Lower Colorado River For Native Riparian Habitat Restoration, Patti Aaron Dec 2001

The Suitability Of Reclaimed Agricultural Lands Along The Lower Colorado River For Native Riparian Habitat Restoration, Patti Aaron

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this paper is to determine the suitability of agricultural lands for use in native riparian restoration efforts under development for the Lower Colorado River Multi-Species Conservation Program. Assuming these fields are productive for crops, would they be productive for cottonwood-willow restoration? There are two aspects to consider: (1) the edaphic conditions required for three major LCR agricultural crops; alfalfa, cotton, and wheat, and (2) whether those conditions are consistent with the conditions required for the restoration of native LCR riparian habitat, primarily Fremont cottonwood (Populus fremontii) and Goodding willow (Salix gooddingii). Using the case study research approach …


An Ethical Framework For Interpreting The United States Endangered Species Act, Cathryn M. Elgin May 2001

An Ethical Framework For Interpreting The United States Endangered Species Act, Cathryn M. Elgin

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this study I argue that a holistic approach is better than an individualistic approach for interpreting the United States Endangered Species Act (ESA). I propose that the use of a holistic ethical framework, based on fundamental environmental philosophy, is better in that it more effectively fulfills the ESA's goals of species and ecosystem conservation. Holistic ethics is based on concern for a community as a whole, while individualistic ethics is based on concern for the individual. A holistic approach, I argue, is more beneficial to nature than is an individualistic approach or other non-holistic approaches. I set up basic …


Southern Nevada Water Authority, Statler Hasley Jan 2001

Southern Nevada Water Authority, Statler Hasley

UNLV Theses, Dissertations, Professional Papers, and Capstones

The arid Southwest of the United States is confronted with increasing water demands. Past efforts to meet water demand have been directed toward development of scarce water resources. Now the times are changing and conservation programs are being instituted to expand supplies for the growing population. In Las Vegas, the tides are shifting to conservation programs. The Southern Nevada Water Authority (SNWA), an agency comprised of the local water utilities, have united to find new sources of water to feed the growing city. SNWA has invested a great deal of money into the conservation programs as an alternative to developing …
