Discursive Horizons of Human Identity and Wilderness in Postmodern Environmental Ethics: A Case Study of the Guadalupe Mountains of Texas

Hood, Robert L. (Robert Leroy) 05 1900 (has links)
Using a genealogy of the narratives of the Guadalupes, I explore three moral identities. The Mescalero Apache exist as caretakers of sacred space. Spanish and Anglo settlers exist as conquerors of a hostile land. The park service exists as captives, imprisoned in the belief that economic justifications can protect the intrinsic value of wilderness. The narrative shift from oral to abstract text-based culture entails a shift from intrinsic to instrumental valuation. I conclude that interpretation of narratives, such as those of the Guadalupes, is not by itself a sufficient condition for change. Interpretation is, however, a necessary condition for expanding the cultural conversation beyond merely instrumental justifications to include caring for wilderness's intrinsic values.

Zjištění očekávání a naplnění seberealizace osob s míšní lézí na vodácké turistické akci / Determination of expectations and fulfillment of self-realization of persons with spinal cord lesion at a boating tournament

Langová, Denisa January 2021 (has links)
Aim of the thesis: The aim of the diploma thesis is the analysis of a questionnaire survey before and after the implementation of a boating tourist event with people with spinal cord lesions, including the formulation of recommendations for practice, which result from this survey. How to possibly eliminate discrepancies in expectations or possible barriers in the implementation of one's own action. The obtained results will point to the perception of the whole event and also to the trends in the organization of boating events for people with spinal cord injuries. I assume that my own research will reveal the potential of positive emotions and motivation of each new participant for self-realization at outdoor events. Comparison of the results of my research with research dealing with similar research topics. Methodology: theoretical-empirical work of a qualitative nature using data collection methods: semi-structured questionnaire of own design, STAI questionnaire. Number of participants 7, age 18 and more (according to registration for the course), the participation of people with spinal cord lesions who have already completed this course in previous years and also the participation of those who have not yet participated in the river rafting course and their experience will be compared and...

Untrammeled by Man? An Ethnographic Approach of Outdoor Recreation Management in Charon's Garden Wilderness

Lukins, Gabrielle M 12 1900 (has links)
Charon's Garden Wilderness Area within the Wichita Mountains National Wildlife Refuge in Oklahoma is a landscape that is granted federal protection through the Wilderness Act of 1964. The discourse of wilderness management is influenced by governmental policies and practice which organize knowledge surrounding the natural landscape, like with the formation and semantics of the Wilderness Act. The Wilderness Act establishes characteristics that are designed to monitor and control the landscape and serve as a baseline and criterion for further wilderness preservation. These characteristics render the wilderness space as governable. Conservation management alternatives are identified which bypass the duality of nature from western society suggested by the discourse of environmental policy. These alternatives are understood under two notions of behaviors and perceptions. The project's goal is to uncover wilderness users' recreation behaviors and perceptions of wilderness as a designated space. Through understanding and assessing user's behaviors and perception of wilderness, alternative policies and practices that offer sustainable management practices and recreation opportunities can be developed.

In Defense of Wilderness: A Documentation of the Social and Cultural Aspects of the Boundary Waters Canoe Area (BWCA)

Brickle, Tyler A. 05 1900 (has links)
My thesis research provides an alternative argument for the protection of the wilderness that extends far beyond that of the purely biological and instead looks at wilderness for the intrinsic value, focusing on the social and cultural aspects. Through an ethnographic approach, I uncovered the how, why, and in what context people connect with wilderness and how people lean on these experiences. Through analysis of the interviews and data that was collected, I was able to identify tangible and intangible values associated with wilderness exploration and understand how these social and cultural aspects manifest themselves in people's day-to-day lives.

Late Pleistocene and Holocene Aged Glacial and Climatic Reconstructions in the Goat Rocks Wilderness, Washington, United States

Heard, Joshua Andrews 01 January 2012 (has links)
Eight glaciers, covering an area of 1.63 km2, reside on the northern and northeastern slopes of the Goat Rocks tallest peaks in the Cascades of central Washington. At least three glacial stands occurred downstream from these glaciers. Closest to modern glacier termini are Little Ice Age (LIA) moraines that were deposited between 1870 and 1899 AD, according to the lichenometric analysis. They are characterized by sharp, minimally eroded crests, little to no soil cover, and minimal vegetation cover. Glacier reconstructions indicate that LIA glaciers covered 8.29 km2, 76% more area than modern ice coverage. The average LIA equilibrium line altitude (ELA) of 1995 ± 70 m is ~150 m below the average modern ELA of 2149 ± 76 m. To satisfy climate conditions at the LIA ELA, the winter snow accumulation must have been 8 to 43 cm greater and mean summer temperatures 0.2 to 1.3 ºC cooler than they are now. Late Pleistocene to early Holocene (LPEH) aged moraines are located between 100 and 400 m below the LIA deposits. They have degraded moraine crests, few surface boulders, and considerable vegetation and soil cover. Volcanic ashes indicate LPEH moraines were deposited before 1480 AD while morphometric data suggest deposition during the late Pleistocene or early Holocene. The average LPEH ELA of 1904 ± 110 m is ~ 240 m and ~90 m below the modern and LIA ELAs, respectively. The climate change necessary to maintain a glacier with an ELA at that elevation for LPEH conditions requires the winter accumulation to increase by 47 to 48 cm weq and the mean summer temperature to cool by 1.4 to 1.5 ºC. Last glacial maximum (LGM) moraines are located more than 30 km downstream from modern glacial termini. They are characterized by hummocky topography, rounded moraine crests, complete vegetation cover, and well developed soil cover. Moraine morphometry, soil characteristics, and distance from modern glacial termini indicate that deposition occurred at least 15 ka BP during an expansive cooling event, the last being the LGM. The LGM ELA of 1230 m is ~920 m below the modern ELA. The climate change necessary to maintain a glacier with an ELA at that elevation for LGM conditions requires the mean summer temperature to cool by 5.6 ºC with no change in precipitation.

Recreation in mountain sheep habitat.

Harris, Lisa Kim. January 1992 (has links)
I described recreational use in mountain sheep (Ovis canadensis mexicana) habitat in the Pusch Ridge Wilderness (PRW), Tucson, Arizona. I also examined human attitudes held by PRW recreationists and homeowners within 1 mile (1.6 km) of PRW boundary towards several mountain sheep management options. I used geographic information system modeling and social science survey methodology. Recreational use along two trails that traverse mountain sheep habitat was frequent (66 individuals/day use Pima Canyon trail, 26 individuals/day use Romero Canyon trail) and primarily limited to the lower 3 miles (4.8 km) of the trails. Compliance with existing dog leash regulations is low (41.8% on Pima Canyon trail, 62.8% on Romero Canyon trail). Recreationists and homeowners within 1 mile (1.6 km) of PRW support the elimination of dogs within PRW and support planned burns of PRW to improve mountain sheep habitat. Recreationists and homeowners also support closing all or parts of PRW to protect the long term viability (>100 years) of the sheep population. Homeowners within 1 mile (1.6 km) of PRW primarily enjoy passive recreational use of PRW (i.e, viewing the wilderness).

The perception of changes in visibility at Class I Parks and Wilderness areas

Parsons, Russ, 1957- January 1987 (has links)
The language of regulations implementing the 1977 Clean Air Act Amendments distinguishes between humanly detectable visibility impairment in Class I Parks and Wilderness areas and the extent to which such impairment adversely affects a park visitor's visual experience. Two lines of environmental perception research have arisen from this distinction, one emphasizing the detectability of visibility impairment, and the other emphasizing a park visitor's experience. This study attempts to deal with issues relevant to both lines of research. Subjects were shown color slides depicting varying levels of visibility in Class I Parks and Wilderness areas under four treatment conditions. A sensitivity gradient emerged from these conditions: Subjects who rated repeated versions of selected vistas for visual air quality were most sensitive to changes in visibility, while subjects who rated a random series of scenes for scenic beauty were least sensitive. Other variables (i.e., scattering angle, and the particular vista being viewed) also proved to have substantial influence on perceptual ratings.
