Influence Of Biochar As A Soil Amendment On Soil Water Content And Wild Blueberry Physiology, Abigayl Novak

Electronic Theses and Dissertations

Maine wild (or lowbush) blueberries (Vaccinium angustifolium Ait.) continue to face challenges imposed by climate change. Reduced frequency of precipitation and increased drought conditions have negatively impacted this crop since it resides in sandy soils with limited retention of water and nutrients. The wild blueberry plants growing in water- and nutrient-poor sandy soils are likely to have poor resilience to drought, resulting in a decline in berry yield during drought years. Thus, there is an urgent need to find a drought management solution for wild blueberries. Compared with other drought management practices, such as irrigation systems, mulching, and adopting drought-resistant …

Developing An Enhanced Forest Inventory In Maine Using Airborne Laser Scanning: The Role Of Calibration Plot Design And Data Quality, Stephanie Willsey

Electronic Theses and Dissertations

Forests provide essential ecosystem services such as carbon sequestration, clean water, lumber, and more. It is important that foresters be able to collect accurate forest inventories, especially in a changing climate. Foresters need to know what is in the forest not only to manage for the economic benefits, but also to manage for social acceptability and ecological soundness to prevent further degradation of these ecosystem services. One way to collect accurate and precise forest inventories is through the utilization of remote sensing products. These enhanced forest inventories (EFIs) can be done at varying resolutions that are contingent on the plot …

Educational Needs Of North Carolina Non-Industrial Private Forest Landowners And Barriers To Meeting These Needs, Robert E. Bardon, Kristin Peters, Rajan Parajuli, K.S.U. Jayaratne

The Journal of Extension

Forest landowners are an important target audience for many state Extension programs. Acknowledging the differences and associations between landownership values, characteristics, and educational preferences of forest landowners should lead to improvement of educational programs and ensuring that educational needs are being met. Through an internet-based survey of forest landowners four distinct landowner typologies were identified based on respondents’ reason for owning forestland. Results also identified the educational needs and barriers to meeting these needs for the landowners. Creating typologies based on attitudinal responses will allow for a more focused approach to developing educational products and services to meet landowner needs.

Toward The Adoption Of New Farming Systems Among Farmers: A Case Study Of Short Rotation Woody Crops In North Carolina, Omoyemeh J. Ile, Eli Typhina, Katie Brannum, Rajan Parajuli, Robert E. Bardon, John S. King

The Journal of Extension

This study explores the human dimensions of the broad-based adoption of Short Rotation Woody Crops (SRWCs) among farmers in North Carolina. We used an actor diagramming and tracing approach to explore factors influencing farmers’ adoption of SRWCs. Results suggest four factors strongly influence the adoption process: 1) market availability, 2) education awareness, 3) funding, and 4) social networking. Based on these results, we recommend that Extension professionals use the following education modules to prompt the adoption of SRWCs practices and potentially adopt other new farming practices: 1) ecological sustainability, 2) financial considerations, 3) harvesting, and 4) community building.

A Review Of Propagation And Restoration Techniques For American Beech And Their Current And Future Application In Mitigation Of Beech Bark Disease, Andrea L. Myers, Andrew J. Storer, Yvette L. Dickinson, Tara Bal

Michigan Tech Publications

The American beech (Fagus grandifolia Ehrh.) has been impacted by the beech bark disease (BBD) complex throughout the northeastern United States for over 100 years, but the disease has been present in the Great Lakes region only for around 20 years, requiring acknowledgement of the evolving context surrounding F. grandifolia. This disease threatens to remove a foundational tree species which is especially important ecologically for wildlife habitat and mast, and as a climax successional species. We review advances in propagation techniques of F. grandifolia with the goal of addressing their use in the rehabilitative restoration of forests affected by BBD. …

Advancing Agroecological Agroforestry: A Vermont Participatory Storytelling And Story Mapping Project, Sydney Blume

Food Systems Master's Project Reports

Agroforestry is the intentional integration of trees into agricultural landscapes. Advancing agroforestry has the potential to support just food system transition, but it must take direction from traditional approaches (culturally-embedded, millennia-old agroforestry practices in forest ecosystems) and agroecology (the movement, science, and practice for just and sustainable food and agricultural systems). An agroecological approach to agroforestry is essential to avoid agroforestry replicating the logics and harms of industrial agriculture and to encourage learning from traditional agroforestry practices, and likewise, traditional approaches to agroforestry can support a transformative agroecological transition through redesign of agroecosystems and shifting perspectives and ethics. This paper …

Multidimensional Investigation Of Tennessee’S Urban Forest, Jillian L. Gorrell

Doctoral Dissertations

Preserving existing trees in urban areas and properly cultivating urban forest conservation and management opportunities is valuable to the ever-growing urban environment and necessary for creating optimal experiences and educational tools to meet the needs of increasing urban populations. This dissertation contains studies investigating several facets of the urban forest, including environmental effects of deforestation and urbanization, tree equity, and urban forest facility management and accessibility. Community education and outreach at arboreta about the importance of the tree canopy can help promote environmental stewardship. A digital questionnaire was electronically distributed to representatives of arboreta certified through the Tennessee Division of …

Grafting Jig For Small-Diameter American Beech: Proof Of Concept And First Print File, Andrea L. Myers, Tara Bal

Michigan Tech 3D Designs

This tool may be useful for grafting other small diameter woody plant species. This jig can be used by non-experts to simplify and standardize the initial cuts necessary for side grafting small-diameter American beech. The initial file which is suitable for 3D printing is available here, whereas we have the intention of undergoing iterative revisions to refine the tool, considering different sizes and modifications. Future versions will be added through the same avenue as advancements are made.

Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2021, Leah English, Jennie Popp

Research Reports and Research Bulletins

Agriculture and associated agricultural activities are major contributors to the Arkansas economy. Agriculture is defined as the sum of agricultural production and processing activities, unless otherwise specified, and includes crop and animal production and processing, agricultural support industries, forestry and forest products, and textile goods. Agriculture contributes to the economy through direct agricultural production and processing, leading to economic activity in other parts of the economy.

This report is the sixteenth in a series that examines agriculture’s economic contribution to the Arkansas economy. The total economic contribution of agriculture (direct, indirect, and induced effects) on value added, employment, and labor …

Disturbance Regimes And Management Strategies Of Mountain Ash Forest Ecosystems In Victoria, Australia; A Literature Review, Zoe Plumb

International Development, Community and Environment (IDCE)

This paper discusses the ecology of mountain ash forests, the disturbances regimes that currently exist in these ecosystems, and finally addresses the current management practices and future management practices. Mountain ash forests are subjected to a wide range of research in the Central Highlands of Victoria, an area approximately 14,000 hectares in range. These forests are dominated by montane ash trees (Eucalyptus regnans F. Muell), which are critically endangered and at risk of collapse, attributed to the decline in large hollow-bearing trees throughout the region. Management of these forests are controlled by the Department of Environment, Land, Water, and …

Factors Influencing The Faunal Recolonization Of Restored Thornscrub Forest Habitats, Audrey J. Hicks

Theses and Dissertations

Tamaulipan thornscrub forests have high ecological and economic value, yet over 90% of these forests have been lost, primarily due to agriculture and urban expansion, and they remain threatened, making them a conservation hotspot. For decades, federal, state, NGO, and corporate entities have been acquiring land and actively or passively restoring these forests, but results have been mixed and seldom monitored. This study characterized and quantified faunal communities of restored thornscrub forest habitats in south Texas and examined the relationships between restored faunal communities and key site characteristics and environmental factors. We surveyed and analyzed mammals, birds, Lepidoptera, and herptiles …

Immediate Response Of Bats To Prescribed Fire And Impact Of Experiences On Women's Self-Image In Natural Resources Professions, Zebria Hicks

All Theses

To inform use of prescribed fire management practice in the southeastern US, we studied its impact on bats, which are important and at-risk species. We evaluated if prescribed fire had a positive, neutral, or negative effect on bat activity in the two weeks following the burns. We recorded bat activity after prescribed burns in February and March 2022 in northwestern South Carolina in select hardwood and pine stands and control sites ≥ 500 m from burn boundaries. We measured insect abundance, canopy cover, basal area, and understory density at each site. We recorded 687 passes during our 45-day study period. …

Top Down Effects And Resource Selection By Coyotes In South Carolina, Alex Jensen

All Dissertations

Top predators play important roles in functioning ecosystems, including regulating the populations of prey species and competing with other predators. However, in the face of global change, many top terrestrial predators have declined in both range and abundance, making room for some smaller predators to expand into new niches. Coyotes (Canis latrans) in North America are a prime example of this – they have rapidly expanded their range in the last 120 years, raising concerns about their impacts on both domestic and wild species. In eastern North America, research has centered around their effects on white-tailed deer ( …

Assessing Recreational User Impacts, Motivations, And Knowledge On The Spread Of Invasive Plant Species In A Managed, Multiple-Use Forest Ecosystem, Crystal Strickland

All Theses

The spread of invasive plants is ecologically and economically detrimental to native ecosystems, animals, and humans. Recreation is one factor that may influence plant dispersal. The impacts of recreation on invasive plant spread are multifaceted and include the physical act of spreading and transporting seeds and vegetation to new areas on clothes, pets, and equipment, as well as the social aspect of outreach and education. Therefore, I used a multifaceted approach to assess the impact of human trafficked areas where recreational activities frequently occur on four known invasive plant species in the Clemson Experimental Forest (CEF) in South Carolina: Microstegium …

Exploring Alternative Methodologies To Estimate By-Species Sawlog Volume In The Southeastern United States, Tara Skiba

Masters Theses

The Forest Inventory and Analysis (FIA) conducts Timber Products Output (TPO) studies to assess timber resource use across the United States. The TPO studies gather information through surveys of primary wood processing facilities to quantify the utilization of roundwood by geographic location, tree species, and timber product type. However, not all responding mills provide information on tree species utilized. As a result, a portion of the reported volume falls into the “unknown/unclassified” softwood or hardwood category, which account for up to 74% of total hardwood/softwood southern volumes in some cases. In addition, the detailed species in the TPO survey forms …

The purpose of this study is to contribute to the knowledge of how environmental factors and different management practices are affecting Coleoptera populations and further assist ecologists in improving management techniques in the future. The insect data in this study was collected over the course of two weeks in the Arkansas portion of the Boston Mountain range. …

Mountain Wetland Soil Carbon Stocks Of Huascarán National Park, Peru, Rodney Chimner, Sigrid Resh, John A. Hribljan, Michael Battaglia, Laura Bourgeau-Chavez, Gillian Bowser, Erik A. Lilleskov

Michigan Tech Publications

Although wetlands contain a disproportionately high amount of earth’s total soil carbon, many regions are still poorly mapped and with unquantified carbon stocks. The tropical Andes contain a high concentration of wetlands consisting mostly of wet meadows and peatlands, yet their total organic carbon stocks are poorly quantified, as well as the carbon fraction that wet meadows store compared to peatlands. Therefore, our goal was to quantify how soil carbon stocks vary between wet meadows and peatlands for a previously mapped Andean region, Huascarán National Park, Peru. Our secondary goal was to test a rapid peat sampling protocol to facilitate …
