Biological capability of selected ecological sites in the western Dakotas

Klempel, Lauren Nicole 09 October 2015 (has links)
<p> Sharp-tailed grouse habitat on the Dakota Prairie Grasslands are assessed by habitat structure with the use of the Robel pole to measure visual obstruction readings (VOR). The purpose of this study was to determine 1) if all selected ecological sites (loamy, thin loamy, and claypan) are biologically capable of producing high structure (VOR > 3.5 in) with 3 years of protection from livestock grazing and 2) if strong and consistent correlations exist between standing crop and visual obstruction among ecological sites and across years. Results showed that 1) all selected ecological sites were biologically capable of producing high structure, 2) strong correlations between standing crop and visual obstruction were not consistent among ecological sites and across years, 3) year effects were evident in plant community composition, and 4) 2,534 kg/ha (se &plusmn; 205.3) of standing crop provides the mean threshold to determine if the selected ecological sites are biologically capable. </p>

Cattle grazing in the national parks| Historical development

Pinto, Robin Lothrop 28 August 2014 (has links)
<p> This dissertation traces the history of cattle grazing at Saguaro NP, Organ Pipe Cactus NM and Fort Bowie NHS in southern Arizona. This collection of studies examines the factors affecting that use, the ranchers who made their living from the landscape, and the federal land managers responsible for sustaining the natural and cultural resources. </p><p> A dominant industry on arid public lands since the Civil War, grazing was altered by a variety of influences: environmental and human-derived. Ranching communities developed from homesteading settlements. Success was determined by climate, topography, and natural resources; social and cultural pressures; economic events and political legislation; and later federal regulations and decisions. </p><p> The first agency to oversee grazing, USFS was under constant pressure to maximize short-term human benefits. The NPS Organic Act of 1916 mandated conservation of natural resources "by such means as will leave them unimpaired for future generations" and yet approved cattle grazing, an extractive use, under USFS management. Park managers were frustrated by grazing practices not under their control. Parks were at a cultural and social disadvantage. Residents and politicians often expressed displeasure at park reservations; communities feared that parks would interfere with local industries. </p><p> Park employees supervised visitors and developed recreation infrastructure; they came with little experience to manage livestock. Lack of funding for research, limited manpower, and political and administrative interference allowed cattle grazing to continue unregulated for decades altering vegetation and enhancing erosion. In the 1960s, changing values from the environmental movement, the waning power of the livestock industry, and the rise of activist scientists impelled NPS to act. Without monitoring data, NPS turned to legal opinions to terminate grazing. </p><p> Now grazing is regulated and carefully monitored. NPS is mandated to incorporate research results into management decisions. Older grazing permits are being retired, but land acquisitions for park additions add new management challenges. Purchasing permits offers a new but financially limited opportunity to protect sensitive lands. Grazing has ended at all three parks, yet ecological changes and historic structures remain. As cultural and administrative legacies, those remnants offer opportunities to interpret a significant regional tradition and an untold controversy.</p>

The role of dignity in rural natural resource governance

Johnson, Tora 25 January 2016 (has links)
<p> Dignity is "an internal state of peace that comes with the recognition and acceptance of the value and vulnerability of all living things" (Hicks, 2011, p. 1). Dignity is a crucial element in effective governance arrangements. This study applies dignity theory, and related theories of natural resource governance and environmental communication, to understand and overcome barriers to effective governance of common pool resources in rural communities. Chapter 1 reviews relevant literature on natural resource governance and develops a theoretical framework for dignity. Chapter 2 applies dignity theory to a contentious comprehensive planning process in a small Maine town in order to understand dignity is constructed and experienced in a collective governance process. Meeting minutes and newspaper articles were coded for themes related to conflict and decision-making. Results showed parts of the planning process ignored dignity considerations. Newspaper articles reported negative or exclusionary events twice as often as positive or inclusive events. Chapter 3 outlines literature relevant to improving capacity of rural communities to adapt to climate change. It then relates a case study from rural Maine in which best practices gleaned from the literature were implemented in creating climate vulnerability assessments and interactive, web-based storm surge mapping tools for use in adaptation planning. Results suggest best practices can enable proactive adaptation without sparking debate over climate science. The survey study described in Chapter 4 examined patterns of beliefs related to climate change and its impacts among people involved in municipal government in a rural Maine county. Results indicate that one-third of respondents were doubtful or unsure about the reality of climate change, but 87% reported observing phenomena related to the warming climate. The web-based survey presented in Chapter 5 examined involvement (perceived relevance and priority) in climate change and other issues affecting rural communities, as well as perceived self- and community efficacy for addressing local problems. Results indicate climate change, per se, is not a high priority, but some climate-related issues do rank highly, suggesting areas for initiating adaptation efforts. Chapter 6 concludes by placing the results of the preceding studies within the context of the dignity framework and presents recommendations for future research. </p>
