Cost Effectiveness Of Greenhouse Gas Reductions Through Afforestation Of Agricultural Land In The Arkansas Delta, Karli A. Moore

Graduate Theses and Dissertations

Sequestration of atmospheric carbon in forested lands offsets carbon emissions from other industries. Conversion of private lands, particularly agricultural tracts in marginal areas, to forests can bolster carbon abatement. The United States government agencies administer some voluntary, incentive-based programs to encourage landowners to adopt production practices with positive environmental outcomes. This policy stream can be used to increase transition of marginal agricultural land to forests, thereby creating new carbon sinks. We analyze an eleven-county study area in the Arkansas Delta to determine feasibility for a subsidy focused on carbon abatement through afforestation. This study area is significant for two reasons: …

Visitor Characteristics, Attitudes, And Management Preferences Of The Bob Marshall Wilderness Complex, Samuel J. Rhodes

Electronic Theses and Dissertations

The Bob Marshall Wilderness Complex (BMWC) encompasses 3 federal wilderness areas and spans over 1.5 million acres of iconic mountains and valleys in northwestern Montana. Here visitors can find a plethora of recreation opportunity that give access to some of the most rugged country that can be found in the lower 48 states. However, managing wilderness areas comes with the challenge of both preserving the natural resources found within their borders and enabling opportunities for recreational experiences. Wilderness social scientists always have striven to determine the type of visitors coming to wilderness, and see what sorts of experiences they pursue. …

Tree Canopy Cover And Potential In Portland, Or: A Spatial Analysis Of The Urban Forest And Capacity For Growth, Jeff Ramsey

Dissertations and Theses

Urban forests have positive impacts on human and ecosystem health, reduce stress on aging stormwater infrastructure, increase property values, and reduce energy consumption. The scale of these benefits ranges from the hyper-local to the global. While the benefits of urban forests can extend well beyond the boundaries of cities, they often do not reach all residents of the city equally. Urban forest policies do not adequately address environmental equity or employ planting strategies with knowledge of the social and political factors that determine the spatial variations of tree canopy extent in cities. Chapter I analyzes the determinants of current canopy …

A Qualitative Case Study Of Student Persistence In A Bachelor Of Science In Forestry Program, Maxwell Holmes

Electronic Theses and Dissertations

Educational leaders in forestry have been challenged to increase and diversify the pipeline of ‘society ready’ foresters. To meet these challenges, leaders must shift their focus to student retention. By understanding the factors that influence student engagement and persistence, these leaders will be better positioned to support students in forestry programs, thus positively impacting retention. This qualitative case study investigated student persistence of second-year forestry students in an undergraduate forestry program. The study was guided by Social Cognitive Theory and Social Capital Theory and explored the malleable psychosocial mechanisms of self-efficacy, sense of belonging, emotion, and well-being proposed by Kahu …

Using The Forestry Reclamation Approach For Reclaimed Surface Mineland In The Western Gulf: Effects On Pinus Taeda Seedling Growth And Survival, Cassie Phillips, Jeremy Stovall, Hans Williams, Kenneth Farrish

Electronic Theses and Dissertations

While land reclamation efforts of surface mines have considerably increased soil stability since the implementation of SMCRA (Surface Mining Control and Reclamation Act), research suggests that resulting soil compaction hinders the productivity of forests post-mining. The Forestry Reclamation Approach (FRA) was developed to improve forest health in the Appalachian region through a five-step process that minimizes soil compaction and establishes a productive forest. The FRA has not yet been tested in the western Gulf Coastal Plain (GCP). The higher clay content of some GCP soils and the dearth of coarse fragments (e.g. cobbles, stones and boulders) may affect reclamation practices …

Analysis And Conservation Of Native Forests At Kessler Mountain Fayetteville, Arkansas, Alan James Edmondson

Graduate Theses and Dissertations

Kessler Mountain in Fayetteville Arkansas has long been recognized for its beauty and natural resources. Parts of Kessler Mountain have been homesteaded and developed in the past, but most of the mountain has remained relatively undisturbed. The planned development of over 4,000 housing units to cover Kessler Mountain stimulated controversy and consideration of other management alternatives. A twist of fate involving an economic recession, a dedicated group of outdoor recreation enthusiasts, and environmental conservationists led to the permanent protection of 384 acres in the Kessler Mountain Regional Park. To help evaluate the natural resources at Kessler Mountain, forest composition, structure, …

Outdoor Education’S Relationship To Adolescent Behavior And Academic Performance In Two East Texas Middle Schools, Trenton Stiefel

Electronic Theses and Dissertations

Historically, a key part of a child’s development was their exposure to and relationship with the world outdoors – nature. The current movement to promote the inclusion of environmental and outdoor education into curricular and extracurricular activities stems from the mounting evidence that experiences in the outdoors may improve a child’s behavior and mood, as well as improve their academic performance. This mixed-methods study hoped to discover whether or not, on average, children improve their academic performance and/or their individual behavior in school when provided with outdoor education learning experiences. The mindset used in outdoor education research may have to …

Scientists, Uncertainty And Nature, An Analysis Of The Development, Implementation And Unintended Consequences Of The Northwest Forest Plan, Gilbert David Miller

Dissertations and Theses

The conflict in the Pacific Northwest between competing visions of how federal forests should be managed resulted in a political stalemate in the early 1990s. The Northwest Forest Plan (NWFP) was initiated to resolve the demands for maintaining ecosystem processes and biological diversity with the social and economic needs for timber harvest. The foundation for the plan rested with the development of ecosystem management. The intent of this research is to explore the events which led up to the adoption of the NWFP, how it was implemented by the US Forest Service and Bureau of Land Management and the subsequent …

Master’S Project: Vermont Town Forest Recreation Planning And Community Assistance Program: The Future Of Forest-Based Outdoor Recreation, Taylor M. Luneau

Rubenstein School Masters Project Publications

The Vermont Town Forest Recreation Planning Community Assistance Program (VTFRP) was a comprehensive community planning process held in ten diverse towns across Vermont. Led by the Urban and Community Forestry Program and the SE Group, the VTFRP helped towns develop a vision for the future management of their forests through open house workshops, site visits, steering committee meetings, and community surveys. The process provided towns with a forest recreation planning toolkit and an individualized action-based forest stewardship and recreation plan. By analyzing data from the community surveys and open house activities across all ten towns, my project considered the recreation …

Unmanned Aerial-Vehicle-Based Measurement Of Urban Forests, Earle W. Isibue

Graduate Research Theses & Dissertations

Human and natural forces continually act on urban forests to producing changes that leading to trees being removed or replanted. Therefore, to manage the urban forest effectively, periodic inventories are needed to ensure that information about the urban forest is current and comprehensive. This task has traditionally been accomplished by manual ground-based field surveys, or more recently by lidar; however, these methods are expensive, either in terms of time, labor, or cost. This project proposes a novel method of using Unmanned Aerial Vehicles (UAVs) to more accurately measure urban tree height and trunk diameter than is currently possible using conventional …

Crown-Level Mapping Of Tree Species And Health From Remote Sensing Of Rural And Urban Forests, Fang Fang

Graduate Theses, Dissertations, and Problem Reports

Tree species composition and health are key attributes for rural and urban forest biodiversity, and ecosystem services preservation. Remote sensing has facilitated extraordinary advances in estimating and mapping tree species composition and health. Yet previous sensors and algorithms were largely unable to resolve individual tree crowns and discriminate tree species or health classes at this essential spatial scale due to the low image spectral and spatial resolution. However, current available very high spatial resolution (VHR) remote sensing data can begin to resolve individual tree crowns and measure their spectral and structural qualities with unprecedented precision. Moreover, various machine learning algorithms …

Perceptions Of Forest Change In The Governmental Region Of Kaffrine, Senegal, Rhiley E. Allbee

Dissertations, Master's Theses and Master's Reports

Sénégal is a semi-arid West African country with a diverse ethnic makeup and a rapidly growing population that is largely rural, predominantly employed within the agricultural sector, and heavily reliant on the harvesting of forest products within state owned forests where populations have usufruct rights. The country experienced significant changes in land cover throughout the 20^th century due to a series of major droughts and large expansions in agriculture. These changes were partially concentrated throughout the region of Kaffrine, where the wooded savannas of the early 20^th century were systematically replaced by agriculture and converted to a shrub …

Island Invasion: The Silent Crisis In Hawaii, Sophia Janssen

Pomona Senior Theses

Keeping out invasive species may, upon first review, seem like a trivial environmental cry from ecologists and deep environmentalists; a belated wish to return to an undeveloped world where nature was pristine. However invasive species create problems that impact all of us and can have far more severe consequences than changing a stunning landscape. These problems are heightened in islands like Hawaii, where the fragile ecosystems have developed over centuries of evolution and adaptation. The introduction of a disease-carrying mosquito can put the people of Hawaii at risk to many vector-born illnesses and create an epidemic, taking human life. The …

Holocene Fire History Reconstruction Of A Mid-Evaluation Mixed-Conifer Forest In The Eastern Cascades, Washington, Zoe Rushton

All Master's Theses

Fire histories of mid-elevation mixed-conifer forests (MEMC) are uncommon, particularly in the eastern Cascades of Washington. As a result, fire regimes and the effects of 20th century fire suppression in these forests are not well understood. In the summer of 2014 a 7.80 meter-long sediment core was extracted from Long Lake, located approximately 45 km west of Yakima, WA, which exists in a grand fir-dominated mixed-conifer forest. Fire activity for the Long Lake watershed was reconstructed using macroscopic charcoal analysis and pollen analysis was used to reconstruct vegetation change through time. Charcoal results show low fire activity in the early …

Asserting Indigenous Identity To Substantiate Customary Forest Claims: A Case Study Of The Dayaks Of West Kalimantan, Indonesia, Charlotte Reinnoldt

CMC Senior Theses

This thesis examines Dayak identity constructions and how they have been and are currently being used to assert customary land rights in forested areas of West Kalimantan, Indonesia. The Indonesian state has required that customary land claims include proof that communities have maintained their indigenous institutions. Drawing from government and NGO reports, academic research, and Indonesian law, a few questions thus are explored: What aspects of identity must be maintained in order to be sufficient to claim customary land rights under Indonesian law? How has recent Dayak mobilization fed into a resurgence in Dayak identity and pride, and vice versa? …

Adaptation Under The Canopy: Coffee Cooperative And Certification Contributions To Smallholder Livelihood Sustainability In Santa Lucía Teotepec, Oaxaca, Meghan C. Montgomery

Graduate Student Theses, Dissertations, & Professional Papers

The collapse and reorganization of global coffee markets associated with the “coffee crisis” have had profound, negative impacts on smallholder producer livelihoods throughout the world. In Mexico, the collapse of the International Coffee Agreement (ICA) coincided with withdrawal of government support for agriculture, which devastated producers dependent on coffee for their livelihoods. Smallholders responded by shifting livelihood strategies to diversify income, migrating, and converting primary forest cover to subsistence crops and pasture to support household livelihood security. In some instances, producers also joined or formed cooperative organizations to access specialty certifications that offer higher priced markets, extension information, and other …

Community-Centered Sustainable Conservation And Ecotourism Planning In The Bossou Forest Reserve, Guinea, West Africa, Destina Samani

Graduate Student Theses, Dissertations, & Professional Papers

Ecotourism management has evolved over the years towards responsible conservation of the natural environment, sustaining the well-being of local people, enriching personal experiences and increasing environmental awareness. The development of a forest reserve is characteristic of the management–visitor–host community interface and the attendant competing interests in the face of new challenges, ideas and theories. In particular, host community participation in the conservation of the forest space tends to breakdown under weak ecotourism management, partly evident by the imbalanced exploitation of ecosystem services resulting in wildlife and society’s inability to cope effectively with the changes (Walker et al., 2016).

The Bossou …
