Constraints And Opportunities Of Conservation Easements As A Tool For Agricultural Preservation In The Blackfoot Valley, Montana, Megan Huth

Graduate Student Theses, Dissertations, & Professional Papers

Huth, Megan, M.S., May 2007 Resource Conservation The Constraints and Opportunities of Conservation Easements as a Tool for Agricultural Preservation in the Blackfoot Valley, Montana Chairperson: Jill Belsky Conservation easements have historically been used by land trusts and government agencies to preserve private land from development and subdivision, to preserve unique geological features, and protect fish and wildlife habitat. The national and Montana state conservation easement legislation does not explicitly state agricultural land as a conservation value that they aim to preserve. As such, land trusts and government agencies that are the holders of conservation easements do not typically identify …

Food Supply Chains And Food-Miles: An Analysis For Selected Conventional, Non-Local Organic And Other-Alternative Foods Sold In Missoula, Montana, Kimberly Spielman

Graduate Student Theses, Dissertations, & Professional Papers

The spatial patterns of the conventional food supply chain have played a significant role in increasing the amount of miles food travels before being consumed. As a result, this has increased the amount of energy that is required to transport food from the farm to the table. The food supply chain links production to consumption. However, as food-miles increase, this link becomes obscure. The food supply chain can be described as having two very distinct parts: the conventional food supply chain and the alternative food supply chain. Business consolidation, and large-scale production, processing, distribution and retail characterize the conventional food …

Forests And Farming: An Analysis Of Rural Livelihood Programs For Poverty Reduction In Eastern Zambia, Garrett Kenneth Olson

Graduate Student Theses, Dissertations, & Professional Papers

This paper investigates the effectiveness of Joint Forest Management (JFM) and agricultural programs at reducing rural poverty in Zambia. Community-based natural resource management (CBNRM) programs in Africa have been aimed at improving livelihoods, creating tangible benefits, and increasing incomes from forests and forest products through the sustainable use and conservation of forest resources. Agricultural programs have often had similar goals regarding improved livelihoods, benefits, food security, and income generation for soil conservation and reduced forest conversion due to agricultural expansion. With increased rates of deforestation and forest conversion, Zambia is in need of effective measures for the sustainable utilization and …

Organizing Rural Communities For Effective Citizen Science Programs, Anna Dean Holden

Graduate Student Theses, Dissertations, & Professional Papers

Citizen science, or the use of volunteers for scientific projects, is becoming a popular way for agencies and organizations to collect data. The benefits of citizen science include saving the agency or organization resources, educating the community about conservation issues, and promoting land stewardship. Currently, many citizen monitoring organizations are based in urban areas, whereas their projects are located near more rural towns. Research shows that demographics such as area of residence can be a factor in the public’s attitude toward any scientific or land management project (Williams et al, 2002; Kellert, 1978, 1985; Vaske et al, 2001). This fact …

Predicting Spotted Knapweed (Centaurea Maculosa) Range Expansion Near Missoula Montana Using Localized Climate And Elevation Data, William Frank Preston Cumming

Graduate Student Theses, Dissertations, & Professional Papers

Since the 1920s spotted knapweed (Centaurea maculosa) has adapted to a variety of habitats, including pastureland, rangeland, hay land, open forests, road sides, and ditches. In 2003 this plant species dominated more than five million acres in Montana, half of the total infestation of noxious weeds in the state. This project demonstrates the utility of using downscaled Parameter-elevation Regressions on Independent Slopes Model (PRISM) data for predicting vegetation movement within a 2°×2° geographical area surrounding Missoula County, Montana. This localized climate change data was correlated against current knapweed range using validation data from the Volunteer for Wilderness Program at the …

Public Archaeology In Montana: A Sample Of University Of Montana Students' Perceptions Of Archaeology And Knowledge Of Local Sites, Helen Alexandra Keremedjiev

Building A Better Local Food System: A Case Study Of The Western Montana Growers Cooperative, Beth Anne Neely

Graduate Student Theses, Dissertations, & Professional Papers

Local food systems aiming to re-create direct links between producers and consumers are emerging in the United States and elsewhere in response to the social, economic, and environmental consequences of the globalizing food market. Despite growing consumer demand for locally produced food, small-scale producers may not have the capacity to meet the needs of wholesale food purchasers, such as restaurants, grocery stores, schools, or hospitals, thus limiting their markets to direct sales to consumers. Wholesale customers, in turn, face a number of barriers to purchasing local food. Producer cooperatives may alleviate some of the challenges faced by wholesale buyers while …

Multifunctional Rural Landscapes: Economic, Environmental, Policy, And Social Impacts Of Land Use Changes In Nebraska, Twyla M. Hansen, Charles A. Francis, J. Dixon Esseks, J. Allen Williams Jr.

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The conversion of farmland near cities to other human uses is a global trend that challenges our long-term capacity to provide food, fiber, and ecosystem services to a growing world population. If current trends continue in the United States, the population will reach 450 million by the year 2050. At the same time, an accelerating change in land use will reduce today’s two acres per person of farmland to less than one acre per person. This is scarcely enough to produce food for our domestic population, without any food available for export – even assuming advances in technology. We need …

The original purpose of this study was to investigate youth needs, specifically in the south western region (the 'South West') of Western Australia, and then to explore how these needs might be addressed in terms of current curriculum and teaching practices. The following research questions guided our investigation:

- What are the educational and occupational aspirations of young people from the South West of Western Australia?

- What do young people identify as influences on their educational and occupational aspirations and attainment?

As the data collection progressed, it was evident to all those involved that, whilst there were expressed needs, …

First-Year Growth And Survival Of Habitat Revegetation Trials On The Lower Colorado River, Mexico, Stephen Dwight Handler

Graduate Student Theses, Dissertations, & Professional Papers

Sweeping changes across the Colorado River watershed in the 20th century resulted in near-complete collapse of the natural communities in the Colorado River Delta (CRD) in Mexico. A brief return of freshwater flows in the 1980s and 1990s showed the riparian corridor remains resilient to past damage, and the CRD remains a vital area for habitat conservation and restoration. This project aimed to test conclusions drawn from similar projects in the United States and show that revegetation projects are possible along the lower Colorado River in Mexico. From November 2006 to October 2007, we tested the effects of various treatments …

Model Estimation Of Land-Use Effects On Water Levels Of Northern Prairie Wetlands, Richard A. Voldseth, W.Carter Johnson, Tagir Gilmanov, Glenn R. Guntenspergen, Bruce V. Millett

Natural Resource Management Faculty Publications

Wetlands of the Prairie Pothole Region exist in a matrix of grassland dominated by intensive pastoral and cultivation agriculture. Recent conservation management has emphasized the conversion of cultivated farmland and degraded pastures to intact grassland to improve upland nesting habitat. The consequences of changes in land-use cover that alter watershed processes have not been evaluated relative to their effect on the water budgets and vegetation dynamics of associated wetlands. We simulated the effect of upland agricultural practices on the water budget and vegetation of a semipermanent prairie wetland by modifying a previously published mathematical model (WETSIM). Watershed cover/landuse practices were …

Evaluation Of Allochthonous And Autochthonous Microbial Populations In The In-Situ Remediation Of Weathered Oil In A Coastal Freshwater Habitat, Kyle Alan Schmidt

LSU Master's Theses

Use of bioremedial technologies has gained popularity in recent decades for application at oil spill sites. While much research has been done on specific case studies along marine shores, such as with the spill of the Exxon Valdez, there still remain questions as to the advantage of active biological treatment vs. natural attenuation in freshwater environments. To examine this question, a comparative study of allochthonous and autochthonous microbial communities ability to degrade weathered oil residuals was implemented at the CITGO Petroleum Refinery in Lake Charles, Louisiana following a spill of approximately 40,000 barrels of slop oil on June 19th, 2006 …

LSU Master's Theses

A Geographical Information System (GIS) linked to a Non-Point Source (NPS) model are being used to predict the effectiveness of storm water management strategies and examine the impact of proposed land use changes on Total Maximum Daily Load (TMDL) attainment. This study tests a methodology for analyzing land use changes and management using GIS analyses of impervious surfaces and AGricultural Non-Point Source (AGNPS) pollution modeling in an approximate 1100 acre urban watershed located in East Baton Rouge Parish (EBRP), Louisiana. The GIS analyses of Total Impervious Area (TIA) quantified increases in urbanization and provided land use data utilized in AGNPS …

Evaluation Of Compliance With The Long Term 1 Enhanced Surface Water Treatment Rule, Racquel Rena Douglas

LSU Master's Theses

Cryptosporidium is a common protozoan parasite that causes cryptosporidiosis, a severe gastrointestinal disease. Currently, there is no antibiotic available to treat the disease. Cryptosporidium has been responsible for several waterborne disease outbreaks in the United States. The largest cryptosporidiosis outbreak in United States history occurred in Milwaukee, Wisconsin in spring 1993. The vulnerability of the United State drinking water supply to waterborne disease outbreak is still prevalent nearly 15 years after the Milwaukee outbreak. In order to effectively control Cryptosporidium, the EPA has strengthened the regulations on turbidity control for filtration performance by implementing the Long Term 1 Enhanced Surface …

Juvenile Crawfish (Procambarus Clarkii) Lc50 Mortality From South Louisiana Crude, Peanut And Mineral Oil, Okey Umejuru

LSU Master's Theses

Nearly every continent has species of crawfish that inhabit wetlands or are near coastal areas where petroleum and other oils are produced, transported, and accidentally released. Most crawfish cannot tolerate polluted water. Thus, they could serve as biomonitors of fossil fuel, biofuel, and other oil releases and assess potential negative impacts such oils have on wetland and coastal ecosystems. The objectives of this study were to estimate the acute toxicity of three oils to juvenile crawfish and determine if toxicity was due to poisoning or interference with oxygen transfer across the gills. Juvenile crawfish (Procambarus clarkii) were tested for acute …

Denitrification Capacity And Denitrifying Bacteria In A Restored Bottomland Hardwood Forest, Mississippi River Alluvial Valley: Hydrological Impacts, Yan Li

LSU Master's Theses

Mississippi River Alluvial Valley (MAV) is one of the most important ecosystems in the United States, and bottomland hardwood forests (BLHs) are a major components of this ecosystem. The ecological and hydrological functions of BLHs can help maintain the diversity of species, groundwater balance, and nutrient removal etc. However, due to the increased human activities in the area, most of the BLHs were converted to agricultural land. Realizing the seriousness of the situation of the ecosystem, a series of programs have been carried out by the U.S. Fish and Wildlife Service (USFWS) and the U.S. Department of Agriculture (USDA) to …

Quantifying The Edge Effects Associated With Predator Removal Blocks On The Nesting Success Of Upland Ducks In North Dakota, Margaret Jean Kuhn

LSU Master's Theses

Much evidence suggests that nest success is one of the key drivers of duck production. Accordingly, for the past thirty years, waterfowl managers have focused their efforts on increasing nest success. One way to increase nest success is through predator trapping. Previous studies have shown that predator trapping increases nest success on different sized trapped blocks. This study attempted to answer the question: does trapping affect nest success on areas directly adjacent to trapped block boundaries? I hypothesized that predator abundance outside trapped blocks would be reduced. I predicted that nest success would decline with distance from the boundary while …

Laboratory Evaluation Of Dunaliella Tertiolecta As A Candidate Algal Species For Tertiary Wastewater Treatment Of Nitrogen And Phosphorus-Laden Effluents Impacting Marine Environments, Ashley Juanika Belle

LSU Master's Theses

Dunaliella tertiolecta was evaluated to determine the effectiveness of utilizing the algal species to reduce the nutrient load of saline wastewater during tertiary treatment. Nutrient uptake studies performed using f/2-Si medium illustrated that Dunaliella tertiolecta favored phosphate uptake over nitrate-nitrogen. Over a 7-day observational period, total phosphorus concentration was reduced by over 97% and the kinetic rate of uptake observed was approximately 0.5 - 1 mg/L/day. Daily nitrate-nitrogen concentrations were highly variable and a model could not be determined to predict uptake behavior. In heavily concentrated nutrient loads, the algae still favored phosphate uptake. However as the nutrient load increased …

Providing The Best Of Both Worlds: Balancing Conservation And Recreation In A System Of Protected Areas In Texas, Kellen Allison Smith

LSU Master's Theses

Societies are becoming increasingly urban and isolated from natural areas. Protecting certain natural areas is vital for building and maintaining resilience in ecological systems for the continued conservation of biodiversity and provision of ecological services. The International Union for the Conservation of Nature and Natural Resources (IUCN) promotes the development of systems of protected areas within nations and regions as a sustainable means of preserving the biodiversity within natural areas. Allowing sustainable ecotourism and wildlife-based recreation activities in protected areas can provide economic incentives to surrounding communities making protection an attractive alternative to more extractive forms of land use. Managing …

Hurricane Modeling In Gis: An Investigation Of Threshold Storm Events Affecting Special Medical Needs Populations In Coastal Louisiana, Kathryn Emily Streva

LSU Master's Theses

Recent hurricane events in coastal Louisiana have emphasized the severe vulnerability of medical special needs (MSN) patients during flood disasters. MSN populations may be comprised of hospital, nursing home or hospice patients; the physically or mentally disabled; medically-dependent individuals requiring life-sustaining equipment or medicines; and frail elderly. Over 150 hospital and nursing home fatalities resulted from Hurricane Katrina in New Orleans. More than four hundred elderly over the age of seventy perished. Chronic diseases and mental health illness were among the top conditions reported in field hospitals, emergency rooms and shelters immediately following the storm. Louisiana MSN facilities and residences …

Biogeomorphic Evaluation Of Caminada-Moreau Maritime Beach Ridges With Respect To Future Restoration Initiatives, Hannon Didier

LSU Master's Theses

Restoration efforts within the coastal zone of southern Louisiana have assumed greater importance in the wake of recent storms and ever increasing sea level rise. A poorly studied geomorphic structure known as the Caminada-Moreau maritime beach ridge complex exists along the southeastern Louisiana coastline between Grand Isle and the Port of Fourchon. Active subsidence in the area has reduced the overall elevation of these structures, decreasing the live cover of its most noticeable feature, stands of Quercus virginiana (live oak), along the ridge spines. Elevation data was gathered along and across four randomly selected ridges in the study area with …

Environmental Factors Influencing The Siting Of Temporary Housing In Orleans Parish, Philip J. Chandler

LSU Master's Theses

The disaster in New Orleans due to Hurricane Katrina showcased the city's many environmental problems. The industrial history of the city, subsidence of the city causing it to be below sea-level, and the fact that the city is protected by levees and pumps were critical elements of the disaster and played a large role in the emergency response. The disaster led to an enormous emergency response by many entities, but the Federal Emergency Management Agency (FEMA) has the lead in these actions. In response to the large number of homes being flooded and unlivable in Orleans Parish, FEMA implemented its …
