Building Relationships With Family Forest Landowners In The Western Upper Gulf Coastal Plain To Enhance Forest Management And Promote Certification, Sandeepa Pantha, Nana Tian, Ana Gutierrez-Castillo, Joshua Adams, Eric Taylor

Journal of Extension

Responsible forest management provides ecological, economic, and societal benefits. Sustaining these benefits in Arkansas, Louisiana, and Texas depends on the forest management practices of 821,000 family landowners who own 32 million acres of forestland. This study uses an innovative network-building approach to support family forest landowners (FFLs), particularly underrepresented ones, by connecting them with professionals through facilitator teams established in each state by an advisory board. This network-building strategy provides supportive networks for FFLs, fostering trust and connections within a more extensive and diverse FFL community. This network encourages cooperative, communication-centered technical support to FFLs within essential landscapes to enhance …

Appraising The Monetary Value Of Trees, Miles Becker, Mark Malmstrom

All Current Publications

Trees have economic value like other property items. Permanently rooted in the ground, trees are considered real property, just as a house on a fixed foundation is real property. Damage or loss of a tree incurs a loss in value to its owner, who may be legally entitled to monetary compensation. This fact sheet discusses tree appraisals by a qualified professional to determine the cost to repair or replace a tree.

Visualizing 25 Years Of Change In The Glades Oak Savanna, Zoe Fieberg

Summer Research Showcase

Oak savannas represent one of the most threatened ecosystems in Minnesota due to changing land use management, particularly absence of fire (Davis, 2001). Frequent burns kill fire-sensitive mesophytic tree species, reducing the dominance of woody understory and allowing for restoration of the oak savanna environment. The GLADES (Grid for Landscape Analysis and Demographic Study) site was established in 1988 in East Bethel, Minnesota to study the effect of frequent burning on oak savanna restoration. Through the use of standardized methods of photography, we compared canopy differences across GLADES between 2001 and 2026. Preliminary observations revealed increased canopy density and reduced …

Long-Term Effects Of Harvesting Disturbance And Site Preparation On Soil Properties And Tree Growth In A Loblolly Pine (Pinus Taeda) Forest, Kyle M. Caccamesi

LSU Master's Theses

Productivity decline between rotations has long been a concern in intensively managed forest plantations. Research done over the last century has provided greater clarity on why this phenomenon occurs. The objective of this research was to observe long-term soil and tree growth characteristics that are likely to be influenced by operational harvesting activities. The experiment was conducted in Washington Parish, Louisiana on a site dominated by Ruston soil series, a well-drained, fine loamy, siliceous and thermic typic Paleudult. A randomized complete block design with 2 x 2 x 2 factorial treatments was used. The treatment factors were harvesting method, fertilization, …

Silviculture For Coastal Forest Resilience: Promoting Forest Regeneration And Managing Invasive Plant Species, Ryan Bohannon

All Dissertations

Coastal forests of the southern United States and the ecosystem services they provide are threatened by an intensifying and interacting suite of disturbances associated with global change. Silvicultural strategies such as enrichment planting, invasive plant management, and browse mitigation treatments can enhance the resilience and adaptive capacity of forests to these threats by promoting sustainable regeneration and recruitment dynamics. To improve our understanding of coastal forest disturbance regimes and their impacts on forest stand dynamics, I conducted a systematic literature review of maritime forest disturbance ecology and identified coastal storms, ungulate browsing pressure, and invasive plants as primary disturbances shaping …

Regional Forecasting Of Southern Pine Beetle Outbreaks In The Southeastern Usa Using Spbom1 With Artificial Intelligence-Based Modeling, Ebere L. Anozie

All Dissertations

Southern pine beetle (SPB; Dendroctonus frontalis) outbreaks are among the most damaging biological disturbances affecting pine forests of the southeastern United States, capable of causing extensive tree mortality, economic losses, and reduced ecosystem resilience. This dissertation evaluated and advanced predictive approaches for SPB outbreak forecasting by integrating systematic review, geospatial modeling, comparative model evaluation, and artificial intelligence-based prediction. First, a systematic review of SPB predictive tools from 1978 to 2024 showed that modeling has evolved from statistical, climatic, and mechanistic approaches to remote sensing, GIS, machine learning, hybrid modeling, and decision-support systems, although many tools remain limited by scale …

Considerations And Challenges For Oak-Pine Woodland Restoration In The Southern Appalachians, Armin Weise

All Dissertations

Appalachian forests in the southeastern United States are composed of fire-adapted communities. These have historically been burned by native Americans and by lightning-ignited fires, causing widespread ignitions across the landscape for millennia that have shaped the forest and the species within it. Many of the more xeric oak-pine forest systems in the region were more akin to woodlands with open midstories, understocked canopies, and a diverse understory layer of herbaceous species and shrubs. With the decline of Native Americans due to disease and forced removal, fire across the landscape declined, a trend compounded by fire-suppression policies put forth by the …

Quaking Aspen On Cedar Mountain, Utah: Status And Update, Jaycee Cappaert, Larissa L. Yocom, Paul C. Rogers, Darren J. Mcavoy, R. Justin Derose

Wildland Resources Student Research

Quaking aspen forests are important communities in the western United States where they provide preferential food and habitat for animals, limit wildfires from spreading, and have favorable aesthetics, among other things. Their putative decline is an issue for ecology and management. We remeasured the aspen population on Cedar Mountain, Utah, to assess changes to its condition since it was originally measured in 2008 and laid the groundwork for continued aspen monitoring on Cedar Mountain. Our objectives were to compare current metrics of stand structure and composition, mortality, crown dieback, bole damage, regeneration, and recruitment, to those of the original inventory. …

New Paradigm Of Forestry And Grassland Research Driven By Artificial Intelligence, Zhang Huaiqing, Jiaojun Zhu, Yang Liu, Tingdong Yang, Tian Gao, Jing Zhang, Xueyan Zhu, Yan Chen, Xian Jiang, Zeyu Cui, Jingwei Tan, Kexin Lei

Bulletin of Chinese Academy of Sciences (Chinese Version)

Addressing the current limitations in forestry and grassland research, particularly in cross-scale system cognition, complex process mechanism representation, and multi-scenario simulation, this study proposes an artificial intelligence-driven paradigm reconstruction framework, to shift the research model from experience-oriented approaches toward data- and intelligence-driven integration. On this basis, the study systematically establishes a multidimensional mapping between artificial intelligence and forestry and grassland research across research objects, processes, and objectives, and clarifies their intrinsic coupling mechanisms and technical pathways. Furthermore, it develops a foundational capability system to support the new paradigm from four key dimensions: data, computing power, models, and applications. By examining …

Sensitivity Of The Mangrove Forest In The Joal-Fadiouth Marine Protected Area (Senegal) To Climate Variability (Rainfall And Temperatures), Eugenie Marie Mossane Sene, Elhadji Faye, Sylvie Brizard Zongo, Hippolyte Ditona Tsumbu, Jean-Claude Micha

Journal of Bioresource Management

Mangroves provide coastal communities with a multitude of ecosystem services. This is the case in Joal-Fadiouth. A study on its mangrove dynamics revealed a decline in area between 1974 and 2004, followed by a gradual trend after it acquired Marine Protected Area (MPA) status in 2004. Given the importance of this mangrove, the research focused on analyzing its evolution associated with rainfall and temperature variability. To do this, Spearman’s Rho correlation coefficient was performed between mangrove areas in 10-year increments from 1974 to 2024 and values of climate parameters studied for each increment, with n (number of pairs) = 6. …

Distribution And Impact Of Cogongrass (Imperata Cylindrica) In Northern Mississippi, Carl R. Pulver V, Ryan E. Burke, Elizabeth Esser, Evan Moore, Ashley Schulz

Endeavors: Mississippi State Undergraduate Research Journal

Cogongrass (Imperata cylindrica) is a non-native, rhizomatous grass that has invaded the southeastern United States. It forms dense mats that outcompete native plants, alters decomposition and microbial assemblages, and has highly flammable litter that alters fire behavior, affecting native plant communities. Though surveys for cogongrass have been conducted in southern Mississippi, the degree of cogongrass infestations in northern Mississippi has remained unclear and concerning. This study aimed to update cogongrass location data for the state and identify problem areas to guide state invasive plant management efforts. To provide a starting point, previously documented cogongrass locations were synthesized from natural history …

Exploring The Relationship Between Tree Dbh And Lichen Cover On Coast Redwood, Grace M. Personeus, Sierra Gittleman, Alisa A. Zarattini

IdeaFest: Interdisciplinary Journal of Creative Works and Research from Cal Poly Humboldt

We investigated the relationship between Diameter at Breast Height (DBH) and lichen cover on coast redwood (Sequoia sempervirens) to see if larger trees had higher percentages of cover. We measured cover using 10 cover classes on the southeastern and southwestern sides of trees in a secondary growth forest. We found a significant relationship between DBH and cover, yet no significant difference between the two sides measured. We suggest that further research with a larger sample size and more varied age classes will provide further insight into the relationship.

Exploring The Effects Of Pest-Induced Hemlock Mortality On Growth In Neighboring Trees, Sidney L. Booher

McNair Culminating Research Projects

Trees provide many important products and services to humans. In particular, tree growth is critical to carbon storage, air and water quality, and helps determine demographic processes like population growth and reproductive success. Importantly, tree growth is sensitive to both abiotic (environmental) and biotic factors and is vulnerable to ecological disturbances. Understanding how tree populations respond to disturbances, like invasive pests, is therefore crucial to formulating timely and effective forest management practices.

Here, I used tree ring analysis to investigate how competition for water between neighboring trees changes following the decline of Eastern and Carolina Hemlock(ECH) trees due to the …

Kolonialisme Iklim Dan Tercerabutnya Pengetahuan Ekologi Tradisional: Sosio-Bioekonomi Sebagai Reorientasi Epistemologis, Viky Arthiando Putra

Antropologi Indonesia

Abstract The global climate change has brought with it a growing stack of conceptual proposals – from green economy to bioeconomy – each presenting itself as a non-extractive economic alternative. Unfortunately, these conceptual claims continue to reproduce colonial logic that subordinates local knowledge. The loss of Traditional Ecological Knowledge (TEK) is not merely an ecological setback: it is a systematic epistemological violence – a product of climate colonialism operating within the architecture of global green programs. This article traces the discourse of green economy, analyzes the loss of TEK as an epistemological problem, and proposes a socio-bioeconomy reorientation as a …

Forest certification promotes sustainable forest management, enhances market access for forest products, and improves ecosystem services. This article addresses forest owners’ hesitations in certifying their forest lands by providing information on the importance and requirements of the three biggest certification systems in the Southern U.S. This study can serve as a resource to raise awareness towards forest certification systems and encourage greater participation among forest landowners.

Integrating Incentive Design And Spatial Prioritization For Climate-Smart Forestry Adoption In South Carolina, United States, Miah Maye Pormon

All Dissertations

Forests provide essential ecosystem services, including carbon sequestration, water regulation, timber production, and habitat provision. However, increasing development pressures and land-use changes threaten forest persistence and long-run ecosystem service provision. Climate-smart forestry (CSF) practices, such as improved forest management and extended rotation, offer opportunities to enhance carbon storage, forest resilience, and economic livelihoods. The effectiveness of these practices depends on forest owners’ participation and the strategic allocation of financial resources or incentives. This dissertation develops an integrated framework that combines behavioral economic analysis and mapping to improve the design of current incentive programs. The first chapter employs the Contingent Valuation …

Forest Overstory Mortality & Recruitment Patterns Eight Years Following Wildfire In The Southern Appalachians, Ruth Cumberland

All Theses

In this study, we investigated patterns of forest overstory mortality and recruitment eight years after wildfire in a large wildfire site the Southern Appalachians, a topic that has not been thoroughly investigated to date. With evidence that pre-fire drought promotes post-fire mortality through impaired physiological function and increased fuel consumption, unknown patterns following wildfire are important to study under shifting climate and land-use conditions. In Chapter 1, three areas of interest were investigated: (a) functional group mortality response to wildfire effects, (b) temporal differences in early (1-3 years) and late (5-8 years) periods of delayed forest overstory mortality patterns following …

Mathematics, Physics, and Computer Science Faculty Articles and Research

Monitoring large-scale afforestation projects in arid and semi-arid environments requires accurate, high-resolution, and repeatable methods to assess tree survival and growth. In this study, we integrated unmanned aerial vehicle (UAV) multispectral imaging with an advanced object detection framework to evaluate vegetation establishment in the Shuayb Al-Budai afforestation site, part of the Imam Turki bin Abdullah Royal Natural Reserve, Kingdom of Saudi Arabia (KSA). Multispectral datasets were acquired using a MicaSense Altum-PT sensor and processed through a masked Region-based Convolutional Neural Network (RCNN) with two backbone architectures: ResNet-101 and VGG19-BN. The Mask R-CNN–ResNet-101 model achieved superior performance, with an overall accuracy …

Forest Characteristics And Avian Community Differences Among Cerulean Warblers (Setophaga Cerulea) Use Types, Dustin Kohler

ATU Scholars Symposium

Avian species are often used to measure the health of an ecosystem, in part because the specific forest structure can significantly impact the avian community. A heterogeneous landscape can support a more diverse avian community and benefit specialist species like the Cerulean Warbler (Setophaga cerulea), a rapidly declining, neotropical migrant that can be found in large deciduous forests. The Ozark Mountains of northwestern Arkansas represent a small core area for the species, but at all sites in the upland Ozarks where Cerulean Warbler research has been conducted, there are fewer individuals than there were twenty years ago; some …

Use Of Basal Tree Cavities By Sylvilagus Aquaticus In Central Arkansas, Heath R. Williams

ATU Scholars Symposium

Basal tree cavities are hollow structures at the base of tree trunks utilized by many wildlife species, including small mammals, furbearers, and bats. Dumyahn and Zollner (2010) demonstrated that swamp rabbits (Sylvilagus aquaticus) use basal tree cavities and speculated that they may be used for thermoregulation at the northern limits of their geographic range or as alternative escape routes. To further investigate swamp rabbit use of basal tree cavities, we placed camera traps approximately 1 m from the entrance of the cavities (n = 43) in various Wildlife Management Areas in central Arkansas. Along with control sites without cavities (n=25), …

Testing The Intermediate Disturbance Hypothesis On Anthropogenic Pressure In Central Alabama, Gavin Terrell

Theses

Biodiversity is fundamental to maintaining ecosystem structure and function globally. Prior to the late 20th century, ecological theory generally predicted that biodiversity would be highest in systems experiencing minimal disturbance. However, Joseph H. Connell challenged this view with the Intermediate Disturbance Hypothesis (IDH), which posits that species diversity peaks at intermediate levels of disturbance and declines under conditions of both low and high disturbance. Although widely cited, the applicability of the IDH to natural systems remains debated, particularly in the context of anthropogenic disturbances and when diversity is measured beyond species richness alone.

This study evaluated the predictions of the …

Status Of Soils In Protected Areas With Different Management Objectives In Lowland Rainforest, Southwest Nigeria, Bolanle Lisa Olajiire-Ajayi, Adeniyi Sulaiman Gbadegesin, Omotosho Ayodele Ogidan

Journal of Bioresource Management

Understanding soil properties is fundamental to sustaining the ecological integrity of protected forest ecosystems. This study examined the influence of two management categories; Strict Nature Reserve (SN) and Natural Park (NP) on soil physicochemical properties within the lowland rainforest of southwestern Nigeria. Fourteen composite soil samples, six from SN and eight from NP, were analyzed for texture, bulk density (BD), pH, organic carbon (OC), total nitrogen (TN), available phosphorus (AP), exchangeable bases (Ca²⁺, Mg²⁺, K⁺, Na⁺), and cation exchange capacity (CEC); base saturation (BS) was also determined. Both management categories exhibited sandy loam to loamy sand textures, typical of gneissic …

Stemflow Dynamics In The Jamari National Forest (Brazilian Amazon): Ii. Solute Concentrations And Flux Dynamics, Jeferson Alberto De Lima, John T. Van Stan Ii, Karolina Lewińska, Agnieszka Dradrach, Jakub Ceglarek, Kelly Cristina Tonello

Biological, Geological, and Environmental Faculty Publications

Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy-derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over a 12-month period in Jamari National Forest (Brazil), we quantified stemflow volume and solute chemistry for 19 trees grouped by diameter at breast height (D: < 10, 10-20 and > 20 cm), crown area (CA: < 30, 30-60 and > 60 m(2)) and bark texture (smooth, fissured and rough). Small-stemmed, smooth-barked trees produced the greatest stemflow …

Assessing Forest Health And Small Mammals After A Limited Suppression Wildfire In Colville National Forest, Samantha J. Kennel

EWU Masters Thesis Collection

In the face of a wildfire crisis, there is a growing need to expand the pace and scale of forest treatments, including the strategic use of wildfire as a management tool. However, ecological outcomes remain uncertain in forests shaped by more than a century of fire suppression. The 2022 Thor Fire, a managed wildfire in the Colville National Forest, Washington, provides an opportunity to evaluate forest health in a relatively understudied system. Using a control–impact design, I established 100 monitoring plots in burned and adjacent unburned forests to assess how wildfire and fire severity influence forest structure, fuels, and tree …

The Evolution Of California Wildfire Governance Through State Bills, Regulations, And Executive Actions, Cassandra Dawn Blevins

History and Political Science | Senior Theses

California faces an escalating wildfire crisis, driven by climate change, drought, and development in fire-prone areas. Despite decades of scientific research on wildfire behavior and risk reduction, catastrophic fires since 2017 raise a critical question: to what extent have California state laws and policies kept up with the intensifying wildfire crisis? Existing scholarship provides extensive insight into wildfire ecology, land-use planning, fuel management, and community resilience, yet it lacks a comprehensive evaluation of whether California’s legislative, regulatory, and executive actions have adapted in a coordinated and evidence-informed manner. In particular, the literature offers limited analysis of how state laws integrate …

Managing The Legacy Of Historical Land Use In Central Appalachia: Soil Health, Carbon Storage, And Restoration Across Disturbed Ecosystems, Kyra R. Dukich

Graduate Theses, Dissertations, and Problem Reports (ETD)

Historical mining, intensive timber harvesting, agriculture, and atmospheric acid deposition have left lasting impacts on soil health throughout the Central Appalachian region, reducing soil productivity, carbon storage, and ecosystem resilience. This thesis evaluated restoration strategies across two long-term research systems in West Virginia to determine how land-use history and soil amendments influence soil health, carbon dynamics, and ecosystem recovery. The first study examined reclaimed mine lands and marginal agricultural soils planted with switchgrass (Panicum virgatum) or willow (Salix spp.) and treated with biochar or inorganic fertilizer. Soil greenhouse gas production, aggregate stability, total soil C:N, pH, and soil organic matter …

Utilizing Plethodontid Occupancy To Assess Initial Ecosystem Responses To Invasive Plant Control Treatment In The Central Hardwoods, Maree Guinevere Dieterich

Graduate Theses, Dissertations, and Problem Reports (ETD)

Invasive plants are a growing concern for land managers, impacting ecosystem resilience and outcompeting native vegetation. To combat this, invasive plant control treatments can assist in reducing the impacts and spread of damaging, non-native plant species. However, intensive treatments completed at large scales have the potential to negatively impact ecosystem services as well. To monitor these impacts, I utilized a well-known indicator in the Central Applachian region, Plethodontid salamanders, to assess impacts of invasive plant control treatments in the Central Hardwood forests. I completed 12 visual samples across 60 sites in West Virginia, USA during Spring and Fall of 2025 …
