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

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, Part 1

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. …

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.

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

Sustainability and Social Justice

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 …

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. …

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 …

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 …

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 ( …

Environmental Factors Affecting Coleoptera Biomass In The Ozark Mountain Range In Arkansas, Hayley J. Springsteen

ATU Scholars Symposium

Coleoptera are often vital in determining biodiversity and conservation techniques. 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, Part 1

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 …

Balancing Interests In Forest Governance In Brazil And Indonesia, Annabel Mccormick Baldy

Environment and Sustainability Honors Papers

Forests play a major role in reducing levels of Greenhouse gasses which are a major contributor to global warming. Conversely, deforestation is a major contributor to climate change. This study examines the concept of good forest governance, dispelling notions that resource use needs to be a zero-sum game. Rather, it identifies local collective agreements as espoused by Elinor Ostrom in Governing the Commons as the best means of balancing the undeniable economic potential of converting forests to other uses (grazing, farming, and mining) with the more sustainable approach of protecting forests for their environmental benefit. For Ostrom, these collective agreements …

Spatiotemporal Analysis Of Covid-19 Lockdown Impact On The Land Surface Temperatures Of Different Land Cover Types In Louisiana, Priscilla Loh, Yaw Twumasi, Zhu H. Ning, Matilda Anokye, Diana B. Frimpong, Judith Oppong, Abena B. Asare-Ansah, Rechael Naa Dedei Armah, Caroline Y. Apraku

Student Presentations

The COVID-19 pandemic posed a serious threat to life on the entire planet, necessitating the imposition of a lockdown mechanism that restricted people’s movements to stop the disease’s spread. This period experienced a decline in air pollution emissions and some environmental changes, offering a rare opportunity to understand the effects of fewer human activities on the earth’s temperature. Hence, this study compares the changes in Land Surface Temperature (LST) that were observed prior to the pandemic (March & April 2019) and during the pandemic lockdown (March & April 2020) of three parishes in Louisiana. The data for this study was …

Water Table Height And Microtopography In Swamps Of Southeastern Michigan As Influences Of Black Ash Tree Establishment And Survival In The Presence Of Emerald Ash Borer, Samantha Chauvin

Honors College Theses

The detrimental impact of invasive species on native biota is a source for many studies spanning all kinds of biological systems. The introduction of emerald ash borer in southeastern Michigan in the early 2000's has decimated the region’s mature black ash tree population, but its regeneration, both asexual (sprouts) and sexual (seedlings) still occurs. The arrangement and features of the wetlands’ land surfaces may play a role in black ash establishment. Black ash is generally found on wet-mesic to wet soils, but rising water table levels due to climate change and overstory tree mortality in on these sites may inundate …

Contrasting Orthophotos By Height, Overlap, And Drone, Edward Ironsmith

Graduate Research Conference

Drones have recently become a mainstay for surveying and modeling of small areas of land in a cost-efficient manner. Yet there are many variables that affect the time, quality, and cost of capturing and generating such products. We look at several of these parameters and discuss the alternatives to minimize cost over a series of projects. The parameters in question include height, overlap, sensor resolution, processing time, drone costs, computer costs, processing costs, time in the field, storage, drone endurance and the likelihood of costly delays. A series of flights using different drones and flight parameters were then used to …

Demography Of Alligator Snapping Turtles (Macrochelys Temminckii) Across A Fishing Pressure Gradient, Luke Micek

Graduate Research Conference

Demographic data are necessary to predict population responses to environmental and anthropogenic stressors and inform conservation efforts for declining species (Weimerskirch 2018, J.Wildl. Manag.).

The western alligator snapping turtle (Macrochelys temminckii; hereafter AST; Fig. 5) is the largest species of freshwater turtle in North America and is being considered for Federal listing as a Threatened Species under the Endangered Species Act (Federal Register 2021). Notably, there is a lack of demographic data of AST in Texas.

Passive fishing gear (i.e., trotlines) have been identified as a pervasive threat to AST populations, although this threat has yet to be quantified inTexas …

Air Pre-Heat System Optimization For Flash Dryers, Sophia Louden

Honors Theses

Primient, a leading producer of food and industrial ingredients made from plant-based, renewable sources is the industrial sponsor for this project. The company is currently using Plate & Frame Heat exchangers to heat up a 40% by-weight glycol and water solution that is then used to preheat the incoming ambient air. Glycol is being added to reduce the risks of freezing in the system during the winter season. It is important to highlight that this fact affects the heat transfer properties of the liquid overall. Since air heating is a highly energy-demanding process, an outlet stream of hot water produced …

Remote Sensing In Mapping Biodiversity – A Case Study Of Epiphytic Lichen Communities, Ida Palmroos, Veera Norros, Sarita Keski-Saari, Janne Mäyrä, Topi Tanhuanpää, Sonja Kivinen, Juha Pykälä, Peter Kullberg, Timo Kumpula, Petteri Vihervaara

Aspen Bibliography

In boreal forests, European aspen (Populus tremula L.) is a keystone species that hosts a variety of accompanying species including epiphytic lichens. Forest management actions have led to a decrease in aspen abundance and subsequent loss of suitable habitats of epiphytic lichens. In this study, we evaluate the environmental responses of epiphytic lichen species richness and community composition on aspen, focusing on the potential of remote sensing by combined hyperspectral imaging and airborne laser scanning to identify suitable habitats for epiphytic lichens. We measured different substrate and habitat parameters in the field (e.g., aspen diameter and bark pH) …

How Aspen Trees Affect Fire Behavior, Emily Lane

Student Research Symposium

Aspen trees (Populus tremuloides) are widely distributed across North America. They provide important wildlife habitat, livestock forage, understory biodiversity, landscape diversity, and aesthetic value. They have also been regarded as important for their ability to act as fuel breaks, at least under average conditions. There have been many qualitative accounts of crown fires dropping to surface fires or being extinguished when they encounter aspen stands. These observations of aspen reducing fire behavior (i.e., flame length, rate of spread, fire intensity) when compared to conifers has led to the idea that aspen could be strategically planted on the landscape, such as …

Genetic Markers And Tree Properties Predicting Wood Biorefining Potential In Aspen (Populus Tremula) Bioenergy Feedstock, Sacha Escamez, Kathryn M. Robinson, Mikko Luomaranta, Madhavi Latha Gandla, Niklas Mähler, Zakiya Yassin, Thomas Grahn, Gerhard Scheepers, Lars-Göran Stener, Stefan Jansson, Leif J. Jönsson, Nathaniel R. Street, Hannele Tuominen

Aspen Bibliography

Background Wood represents the majority of the biomass on land and constitutes a renewable source of biofuels and other bioproducts. However, wood is recalcitrant to bioconversion, raising a need for feedstock improvement in production of, for instance, biofuels. We investigated the properties of wood that affect bioconversion, as well as the underlying genetics, to help identify superior tree feedstocks for biorefining.

Results We recorded 65 wood-related and growth traits in a population of 113 natural aspen genotypes from Sweden (https://doi.org/10.5061/dryad.gtht76hrd). These traits included three growth and field performance traits, 20 traits for wood chemical composition, 17 traits for wood anatomy …

The Methylation Landscape Of Giga-Genome And The Epigenetic Timer Of Age In Chinese Pine, Jiang Li, Fangxu Han, Tongqi Yuan, Wei Li, Yue Li, Harry X. Wu, Hairong Wei, Shihui Niu

Michigan Tech Publications, Part 1

Epigenetics has been revealed to play a crucial role in the long-term memory in plants. However, little is known about whether the epigenetic modifications occur with age progressively in conifers. Here, we present the single-base resolution DNA methylation landscapes of the 25-gigabase Chinese pine (Pinus tabuliformis) genome at different ages. The result shows that DNA methylation is closely coupled with the regulation of gene transcription. The age-dependent methylation profile with a linearly increasing trend is the most significant pattern of DMRs between ages. Two segments at the five-prime end of the first ultra-long intron in DAL1, a conservative age biomarker …

Forming Regional Soil Carbon Networks To Support Effective Climate Change Solutions, Gregory Lawrence, Ivan Fernandez, Scott Bailey, Colin Beier, Alexandra Contosta, Erin Lane, Peter Murdoch, Lucas E. Nave, Angelica Quintana, Donald Ross, Alissa White

Michigan Tech Publications, Part 1

Sequestration and storage of organic carbon (C) in soil is an essential component of climate change mitigation and fundamental in promoting the health and climate resilience of soils. Sources of available soil C data are increasing, which complicates efforts to consolidate the data in forms that can be readily used by stakeholders. Spatial and temporal gaps in data availability also limit the quantification of changes in soil C through space and time. Improved coordination among producers and users of soil C data would provide data compatibility at the spatial and temporal resolution required for C monitoring, accounting, and verification of …
