Coastal Land Loss And Collaborative Resource Governance: The Case Of Plaquemines Parish, Louisiana, Nandini Seth

University of New Orleans Theses and Dissertations

The research, presented here, is about the collaborative governance and adaptive management in coastal planning efforts of Louisiana. Fundamental conflict, between the idea of environmental conservation and developmental growth, has always existed in the coastal regions. The presence of the large number of environmental laws, at various levels of government and their different management objectives for utilization of coastal resources, requires study of intergovernmental relationship. Taking Plaquemines Parish as a case in point, this thesis will, therefore, review the critical restoration plans for intergovernmental coordination and conflicts. It will also provide recommendations, for elected representatives and policy makers, with an …

Analysis Of Hurricane Preparedness Levels And Evacuation Intent For South Carolina Coastal Residents, Wesley Chad Seigler

Theses and Dissertations

Many communities across the nation, especially those in coastal areas, are experiencing extensive growth and expansion. This growth and the associated need for additional infrastructure, goods and services, and basic human needs often place people and the things they value in harm’s way due to the threat of a natural disaster. In order to properly prepare and mitigate disaster impacts, individuals and communities must view disasters as events that will likely occur at least once during their lifetime rather than simply outside possibilities. Residents of coastal communities must prepare for potential impacts from hurricanes and resulting storm surges and must …

An Analysis Of U.S./Canadian Fisheries Policy In Regards To Pacific Salmon And The Preservation Of Indigeneity In The Pacific Northwest, Michael James Lockwood

Masters Theses, 2010-2019

For more than 160 years, the Pacific salmon has been an important resource for the United States and Canada. However, it has been overexploited. Proper management of the species is essential not only for maintaining healthy populations but also maintaining the interests of diverse stakeholders. One set of stakeholders consists of the indigenous peoples of North America because the Pacific salmon are crucial to their food, social, and ceremonial traditions.

This thesis explores the impacts of Canadian and U.S. public policies on the cultural integrity of native peoples in the Pacific Northwest, specifically as those peoples rely on wild Pacific …

Policy Context Of The Endemic Flora Of The Maltese Islands In A Changing Taxonomic Landscape, Clara Agius

Masters Theses, 2010-2019

The degradation of the environment since the Industrial Revolution has been a turning point for legislation, leading to many countries, including EU states, to create legislations that conserve the environment. These legislations are based on scientific facts. This can create a divide between policy and science, as science and scientific methods are constantly changing, while policy has to keep up. Scientific facts of yesterday, may not necessarily be the same as today. This divide between science and policy may have implications on the designation of Protected Areas. One of the criteria of a Protected Area is the protection of an …

Examining The Effectiveness Of Ecotourism As A Funding Source For Protected Area Management In Guyana, Jordan S. Flagel

Masters Theses, 2010-2019

Protected areas in tropical rainforests serve many important ecosystem services, including carbon sequestration. These areas are often in need of donor or grant funding to operate as governments in tropical forested countries are not always able to provide adequate funds for protection. This paper focuses on the Iwokrama International Center for Rainforest Conservation and Development in the South American country of Guyana, which has had funding issues since the global economic crisis of 2008 and an accompanying shift in donor country financial priorities. Increasing the amount of sustainable ecotourism in the Iwokrama reserve was identified as a potential source for …

Carbon dioxide (CO₂) levels in the atmosphere have been experiencing a rapid rise since the start of the Industrial Era. Human activities have been recognized by the scientific community as the main contributors to CO₂ emissions by way of the combustion of fossil fuels such as coal, oil, and natural gas. Scientific consensus about human-induced climate change has been recognized since 1992 by the work of the United Nations Framework Convention on Climate. Since then, …

Polyculture Bioremediation: An Analysis Of Potential Nitrogen Assimilation And Removal By Mya Arenaria, Gracilaria Tikvahiae And Ulva Lactuca Harvests In The Corsica River, Md, Kathleen Hemeon

Masters Theses, 2010-2019

An analysis of nitrogen bioremediation in a tidal tributary of the Chesapeake Bay by the use of a hypothetical bivalve and macroalgae polyculture covering 1%, 3% and 5% of the Corsica River bottom area. This study was performed to illustrate the role ecosystem services play in managing diffuse watershed pollution, particularly nitrogen, resulting in water quality and living resource degradation. Excess concentrations of nitrogen in the Corsica River estuary lead to seasonal eutrophication and subsequent hypoxic events. Mya arenaria L. and Gracilaria tikvahiae (McLachlan, 1979) were chosen for this theoretical study due to their high assimilative capacities for nitrogen and …

Land Use Interactions Drive Southwestern Ontario Stream Nutrient Concentrations, Renee L. Lazor

Identifying land use drivers of tributary nutrient concentrations and describing the magnitude and direction of their relationship are critical activities to improvement management of water quality in basins draining into the Great Lakes. The overarching goal of my thesis was to quantify the cumulative influence of spatial patterns in land use and land cover on variation of nutrient concentrations in tributaries of the Great Lakes. Biweekly water chemistry samples were collected in 29 streams located in southern Ontario between May and November, …

Phenology And Effects Of Dams On The Success Of Atlantic Salmon Smolt Migrations In The Penobscot River, Maine, Daniel S. Stich

Electronic Theses and Dissertations

Atlantic salmon Salmo salar populations are diminished throughout their range and high marine mortality is among the drivers of the failure of many stocks to recover. A goal of salmon recovery is to maximize the number of juvenile ‘smolts’ entering the ocean to offset loss therein. Dam removals and changes to hydropower allocation in Maine’s largest river, the Penobscot River, have occurred as part of the Penobscot River Restoration Project (PRRP). These activities, in addition to stocking have the potential to influence the number of smolts reaching the ocean. Telemetry was used to investigate factors influencing initiation of migratory behavior, …

Investigating The Effects Of Urbanization On Residual Forest Soils In Knox Co., Tennessee, Benjamin Lee Reichert

Masters Theses

As the process of urbanization advances across the country, so does the importance of urban forests, which include both trees and the soils in which they grow. Soil microbial biomass, which plays a critical role in nutrient transformation in urban ecosystems, is affected by factors such as soil type and the availability of water, carbon, and nitrogen. However, the microbial dynamics of urban forest soils remain largely unknown. A key mechanistic link between plant species diversity and ecosystem function is heterotrophic microbial communities that inhabit the soil and mediate principal processes that control ecosystem carbon (C) and nitrogen (N) cycling. …

The Challenges And Opportunities Throughout The Life Cycle Of Landscape-Scale Collaborative Conservation Organizations: Case Studies In The Southern Appalachians And The Northern Rockies Ecosystems, Jennifer Thomsen

All Dissertations

Currently our natural environment is threatened by climate change, habitat fragmentation, and other transboundary issues. To address these problems, it is thought that conservation organizations and land management agencies should attempt to manage at larger geographic scales and across political boundaries. The Crown Managers Partnership (CMP) and the Southern Appalachian Man and the Biosphere Cooperative (SAMAB) are two such organizations that work at an ecoregional scale to support collaboration among agencies, aboriginal groups, conservationists, scientists, and other stakeholders for the conservation and restoration of the Northern Rocky Mountain and the Southern Appalachian regions in North America. Over the past decades, …

Watershed Delineation In The Field: A New Approach For Mobile Applications Using Lidar Elevation Data, Samuel Adam Noel

Open Access Theses

With the advancement of mobile devices, opportunities to take watershed management tasks out of the office and into the field can be realized. In turn, field workers can utilize these technologies to expedite the decision-making process so that they may focus on meeting with clients and addressing agricultural watershed management issues. High-resolution (∼1.5 m postspacing) elevation data gathered by light detection and ranging (LiDAR) provides the topographic detail necessary to model hydrology at the field-scale (∼1 km2).

Non-artifactual surface depressions lead to erroneous surface flow patterns when using existing algorithms. So a sequential depression-filling algorithm (SDFA) has been developed to …

Determining The Association Between The Structure Of Stream Benthic Macroinvertebrate Communities And Agricultural Best Management Practices, Roger Holmes

Electronic Thesis and Dissertation Repository

Farmers have been encouraged to adopt more sustainable farming practices (BMPs) that mitigate adverse agricultural effects on the natural environment. However, the ability of BMPs to protect or restore riverine systems continues to be questioned due to limited evidence directly linking BMP use with improved ecological conditions. The exclusion of hydrological pathways in previous field studies may explain why a direct link has not yet been established. The goal of this study was to assess the association between benthic macroinvertebrate community structure and the number and location of agricultural BMPs. Macroinvertebrates and water chemistry were sampled in 30 headwater catchments …

Effects Of Large Scale Growing Season Prescribed Burns On Movement, Habitat Use, Productivity, And Survival Of Female Wild Turkey On The White Rock Ecosystem Restoration Project Of The Ozark-St. Francis National Forest, Henry Tyler Pittman

Graduate Theses and Dissertations

Restoration of woodland and savanna ecosystems has become a common management strategy in the Central Hardwoods region. Over the past two decades forest managers have implemented woodland and savanna restoration at the landscape level (≥10,000 ha), especially using early growing season prescribed fire. The implementation of the restoration strategy has coincided with declines of Eastern Wild Turkey (Meleagris gallopavo silvestris) in many treated areas causing concern that early growing season prescribed fire was impacting wild turkey. We initiated our study to examine the effect of woodland and savanna restoration on the ecology and habitat of wild turkey in the Ozark …

Use Of Unmanned Aerial Vehicles (Uav) For Urban Tree Inventories, Brian Ritter

All Theses

In contrast to standard aerial imagery, unmanned aerial systems (UAS) utilize recent technological advances to provide an affordable alternative for imagery acquisition. Increased value can be realized through clarity and detail providing higher resolution (2-5 cm) over traditional products. Many natural resource disciplines such as urban forestry will benefit from UAS. Tree inventories for risk assessment, biodiversity, planning, and design can be efficiently achieved with the UAS. Recent advances in photogrammetric processing have proved automated methods for three dimensional rendering of aerial imagery. Point clouds can be generated from images providing additional benefits. Association of spatial locational information within the …

Spatial And Temporal Analysis Of Land Cover Change, Sedimentation And Water Quality In The Lake Issaqueena Watershed, South Carolina, Cassie Pilgrim

All Theses

Soil erosion and increased sediment yields within a watershed lead to impaired water quality, decreased availability of wildlife habitat and reduced recreational opportunities. While some sedimentation occurs naturally within a water system, most erosion processes are the result of anthropogenic activities across a landscape, namely changes in land use and land cover (LULC). This study was conducted to determine temporal and spatial sedimentation trends in the Lake Issaquena watershed using sonar logging equipment, geographic information systems (GIS) and limited hydrologic data from the Soil Conservation Service (1941 and 1949). Sediment deposition was analyzed in relation to several key factors that …

Measuring Carbon Dioxide (Co2) Flux Of Agricultural Practices In Sub-Saharan Africa, Debra Blumberg O'Dell

Masters Theses

Agriculture has an important role in addressing two of the world’s most pressing problems: meeting global food demand and mitigating climate change. If agriculture is not practiced sustainably it will fail to meet future food demand and likely intensify the pace of global climate change. There are some agricultural practices, such as Conservation Agriculture, that can produce food sustainably and have the potential to mitigate climate change. However it is not clear which agricultural practices contribute to climate mitigation and by how much. By measuring the carbon dioxide (CO2) emissions of specific agricultural practices, the ability of practices to sequester …

Survival, Growth, And Settlement Of Dreissena Rostriformis Bugensis Veligers In Low And High Calcium Waters, Emma Ruhmann

UNLV Theses, Dissertations, Professional Papers, and Capstones

Populations ofDreissena rostriformis bugensis(quagga mussels) have continued to spread throughout the western United States since their discovery in the Boulder Basin of Lake Mead, NV-AZ in early 2007. Today, quagga mussel specific research is still lacking and the physicochemical characteristics of aquatic systems required by quagga mussels to successfully establish is not fully understood. This includes an absence of research in aquatic environments in the western United States and on quagga mussel veligers (larval stage). Calcium is considered the defining factor for determining if a lake or river is suitable for quagga mussel establishment. The minimum calcium threshold for invasion …

Evidence-Based Decision Making In Coastal Oregon: Increasing The Effectiveness Of Policy And Management Decisions, Kaitlin Goldsmith

Environmental Science and Management Professional Master's Project Reports

Changing climatic conditions, demographics, and land uses are projected to alter the provisioning of ecosystem services in estuarine, coastal and nearshore marine ecosystems, necessitating mitigation and adaptation policies and management. The current paradigm of siloed research efforts occurring in parallel to, rather than in collaboration with, decision-makers will be insufficient for the rapid responses required to adapt to and mitigate for projected changing conditions in coastal areas. Here, I suggest a different paradigm: one where research begins by engaging decision-makers in the identification of priority research needs (biophysical, economic, and social), and in which researchers analyze and present data in …

Cost Benefit Analysis Of The Keystone Xl Pipeline, Daniel Carr

Honors Theses

The Keystone XL pipeline is one of the most controversial topics in North America over the last five years. The debate is based on the trade‐off between Canadian oil sands as a usable energy resource and the environmental effects associated with the extraction and refining of the oil. The green house gasses emitted from the extraction and refining of oil sands produces several environmental concerns that make the proposed pipeline controversial. On the other hand, Canadian oil companies see a significant benefit from the ability of Canadian oil reaching international markets. TransCanada, a 79.99 percent owner of the pipeline, conducted …

Proving Widespread Deforestation Of The Ancient Mediterranean As Myth: A Detailed Examination Of How Anthropogenic Activities During Antiquity Affected The Mediterranean Landscape, Carolyn Hooper

Honors Theses

This thesis examines the debate surrounding the possible deforestation of the ancient Mediterranean landscape through anthropogenic activities. Until the ancient Mediterranean landscape is understood more clearly, it is impossible to impose current beneficial land-use laws in order to conserve and preserve the future landscape of the region. Currently there are three predominant views surrounding the debate: (1) deforestation did occur and drastically altered the landscape from a forested region to a more desert-like region, (2) human activities did not cause deforestation, rather the Mediterranean has always been home to a distinct and resilient landscape that is able to regenerate following …

Integrating Traditional Ecological Knowledge With Modern Day Ecosystem Management And Restoration Practices, Leialani O. Hufana

Master's Projects and Capstones

Traditional ecological knowledge (TEK) is a fairly new area of research that can supplement science research and modern day ecosystem management practices. Indigenous cultures and local communities have been using and passing on TEK in forestry, agricultural, and aquaculture/marine ecosystem management. Through a review of literature, TEK in Hawaiʻi was compared to TEK in other countries. TEK was also compared to modern day ecosystem management practices to determine if TEK could be integrated. In Hawaiʻi an ahupuaʻa, a land transect that cuts the islands in sections from mountain to sea, was an integrated watershed based management system. TEK in ahupuaʻa …

Deep Energy Retrofits Using The Integrative Design Process: Are They Worth The Cost, Daniel S. Bertoldi

Master's Projects and Capstones

The McKinsey Global Initiative identified existing building retrofits as an integral component to achieve a 75% reduction in greenhouse gas emissions in the United Sates by 2050 (Fluhrer, Maurer, & Deshmukh 2010). However, this will require energy efficiency retrofits for existing buildings to be deployed more frequently and achieve higher energy savings on average. Deep Energy Retrofits using the Integrative Design Process can result in 30-60%+ energy savings in office buildings. Because Deep Energy Retrofits require higher upfront capital costs, in an economy still recovering from the economic downturn, financial decision makers may not be inclined to invest more capital …

What Role Can Ceqa Play In Reaching Ghg Emissions Reductions Goals Set Forth In Ab 32 – An Analysis Of Ceqa, Ab 32, And Recommendations For Ceqa Reform, Eleanor Gilbert

Master's Projects and Capstones

The Global Warming Solutions Act of 2006 (AB 32) intends to reduce the effects of climate change through several mechanisms, including greenhouse gas (GHG) emissions reduction. AB 32 established a statewide GHG emissions goal, which requires California to decrease its GHG emissions to 1990 levels by 2020. The California Environmental Quality Act (CEQA) is an environmental assessment law adopted in 1970 that requires lead agencies (private developers, public agencies, etc.) to consider and disclose the potential significant environmental impacts of new development projects the lead agency is planning. CEQA has attracted much controversy since adoption and continues to be the …

This paper will examine the current vegetation management strategy of California’s major utility companies and determine whether a more comprehensive integrated vegetation management program could …

Recovery Of Oregon Coast Coho Salmon (Onchorhynchus Kitsutch) Through Restoration Of Freshwater Habitats, Andrew P. Lutz

Master's Projects and Capstones

Pacific salmon populations are significantly lower than historic levels on the Western Coast of the United States. The Oregon Coast coho salmon Evolutionary Significant Unit (ESU) was listed as threatened under the Endangered Species Act in February 2008. The total number of adult coho salmon returning to Oregon Coast rivers today are between 5-20% of historic levels. Since the 1980s, restoration of freshwater habitat has become a common practice in the attempt to recover Pacific salmon populations. I used two databases, the Oregon Watershed Restoration Inventory, and the Salmon Recovery Tracker, to analyze habitat restoration and coho salmon population recovery …

Refining Dendrochronology To Evaluate The Relationship Between Age And Diameter For Dominant Riparian Trees In The Redwood Creek Watershed, Devin Barry

Master's Projects and Capstones

Methods of dendrochronology by means of incremental coring

have been refined in this study for specific use in northern

California riparian floodplains. Little information is available

on riparian dendrochronology because of the challenges of

analyzing riparian tree species. Three dominant tree species

(Alnus rubra, Umbellularia californica, Acer macrophyllum)

in the floodplain of Redwood Creek were evaluated for the

relationship between age and diameter at breast height (DBH)

using a least squares linear regression analysis. Through this

study, complications with analysis for the riparian tree species

led to a more thorough investigation as to enhancing core

quality and annual growth ring …
