The Impacts Of Prescribed Burning And Mechanical Thinning On Insect Communities In The Arkansas Ozarks, 2020 Arkansas Tech University
The Impacts Of Prescribed Burning And Mechanical Thinning On Insect Communities In The Arkansas Ozarks, Aaron P. Tormanen
Theses and Dissertations from 2020
Insects are important in woodland ecosystems due to their role as pollinators and as prey for bats. My research investigated the relationships between forest management, vegetation, and insects in the Ozark National Forest in Arkansas. I selected 30 stands burned at varying frequencies in the last 12 years. Twelve of these stands were burned and mechanically thinned, 12 were only burned, and 6 were untreated. I deployed blacklight traps and malaise traps in each stand monthly from mid-March to mid- November 2019. Over 42,391 insects were collected, and Lepidoptera was the most abundant order. Insects were dried, weighed, and ...
Carbon Sequestration In A Restored West Michigan Oak Savanna: Implications For Management Practices, 2020 Grand Valley State University
Carbon Sequestration In A Restored West Michigan Oak Savanna: Implications For Management Practices, Jeffrey A. Heise
The savanna system is an ecosystem (i.e. a transitional ecosystem) that lies between forest and grassland ecosystems. They occur across the world in various forms, but in the North American Midwest they are specifically oak savannas: systems where the open overstory is dominated by various species of oak (Quercus spp.) and the understory consists of carbon-rich prairie grasses and forbs. This ecosystem is a highly degraded ecosystem and has lost almost 99% of its former range due to agriculture and fire suppression. Since savannas are fire-evolved systems, they are maintained by and require fire as a regular disturbance to ...
Forest Landscape Structure Influences The Cyclic‐Eruptive Spatial Dynamics Of Forest Tent Caterpillar Outbreaks, 2020 Université de Montréal
Forest Landscape Structure Influences The Cyclic‐Eruptive Spatial Dynamics Of Forest Tent Caterpillar Outbreaks, Louis‐Etienne Robert, Brian R. Sturtevant, Daniel Kneeshaw, Patrick M. A. James, Marie‐Josée Fortin, Peter T. Wolter, Philip A. Townsend, Barry J. Cooke
Natural Resource Ecology and Management Publications
A fundamental question in forest insect ecology is the role of forest landscape structure, particularly the amount and spatial configuration of host tree species, in shaping the dynamics of recurring forest insect outbreaks. For forest tent caterpillar (FTC), independent studies do not converge on a singular conclusion, although all indicate that forest structure influences outbreak dynamics. These studies also vary in how they treat climate as a covariate. We evaluated the relative importance of host forest landscape composition and configuration, as well as climate, for their influence on FTC outbreak cycling in the twentieth century. We predicted that FTC outbreaks ...
A Preliminary Investigation Of The Impact Of Forest Management Practices On Microhabitat Abiotic Variables In The Southern Appalachian Mountains, Jasmine Williamson, Allison Bailey, Jacob Lougee, David Patterson, Jessica Patterson
Georgia Journal of Science
Existing research has demonstrated that forest management practices (e.g., clear-cutting, planting) can dramatically impact animal communities. This is particularly the case with amphibian populations due to their sensitivity to microhabitat alterations. However, few studies have investigated the manner by which forest management practices impact the abiotic variables most relevant to healthy amphibian populations. In this study we investigated how spatially localized forest management practices (i.e., at the scale of hundreds of meters) alter the microhabitat variables that have been shown important to amphibian population distributions. We assessed the relationship between forest composition and microhabitat abiotic variables across three ...
Aspen Next Generation: Conversations From Southern Colorado And Northern New Mexico, 2020 Northern Arizona University
Aspen Next Generation: Conversations From Southern Colorado And Northern New Mexico, Dan Binkley, Bill Romme
Aspen trees and forests are especially important in the Rocky Mountains. Aspens add beauty to landscapes, foster high diversity and productivity of understory plants, provide for the habitat needs of many species of animals, and moderate fire behavior. There is a perception that aspen trees and stands are not regenerating well in southern Colorado and northern New Mexico; cohorts of trees younger than a few decades are scarce, at least in some areas. The next generation of aspen in the southern Rockies will be influenced by land use decisions, including harvesting, fire policy and management, and browsing by livestock and ...

The reintroduction of fire to landscapes where it was once common is considered a priority to restore historical forest dynamics, including reducing tree density and decreasing levels of woody biomass on the forest floor. However, reintroducing fire causes tree mortality that can have unintended ecological outcomes related to woody biomass, with potential impacts to fuel accumulation, carbon sequestration, subsequent fire severity, and forest management. In this study, we examine the interplay between fire and carbon dynamics by asking how reintroduced fire impacts fuel accumulation, carbon sequestration, and subsequent fire severity potential. Beginning pre-fire, and continuing 6 years post-fire, we tracked ...
The Ecological Value Of Spruce Plantations In Massachusetts, 2020 University of Massachusetts Amherst
The Ecological Value Of Spruce Plantations In Massachusetts, Calvin Ritter
The establishment of monoculture plantations of exotic tree species is common practice for supplementing native timber stocks. Such plantations typically provide inferior habitat for wildlife compared to native forest, which may result in a net reduction in biodiversity. However, some studies report that plantations may increase net biodiversity at the landscape scale by introducing novel habitats or supplementing existing natural forests. Using point count surveys, I examined six mature Norway spruce (Picea abies) plantations in western Massachusetts in 2016 and 2017 to evaluate bird use of these habitats relative to native forest stands. Count data were analyzed using N-mixture models ...
Floodplain Forest Regeneration Dynamics In The Lower Mississippi River Alluvial Valley, 2020 Louisiana State University and Agricultural and Mechanical College
Floodplain Forest Regeneration Dynamics In The Lower Mississippi River Alluvial Valley, Whitney Anne Kroschel
LSU Doctoral Dissertations
Floodplain forest species diversity is driven, in part, by variation in disturbance regime. Flood patterns create heterogeneity in microsite quality from small differences in elevation across a floodplain which, in turn, influence flood timing and duration. Differences in species’ regeneration niches in relation to hydrologic patterns can account for long-term coexistence of various species. In the past century floodplain forests have exhibited a wide range of changes in stand development and species composition as a result of altered hydrology in rivers and floodplains. I evaluated the role of regeneration in floodplain forest systems of the Lower Mississippi River Alluvial Valley ...

Retention Forestry Influences Understory Diversity And Functional Identity, 2020 Iowa State University
Retention Forestry Influences Understory Diversity And Functional Identity, Miranda T. Curzon, Christel C. Kern, Susan C. Baker, Brian J. Palik, Anthony W. D’Amato
Natural Resource Ecology and Management Publications
In recent decades, a paradigm shift in forest management and associated policies has led to greater emphasis on harvest practices that retain mature, overstory trees in forest stands that would otherwise be clear-cut. While it is often assumed that the maintenance of compositional and structural complexity, such as that achieved through retention forestry approaches, will also mitigate negative impacts to functional diversity, empirical evidence of this relationship is sparse. We examined the effects of an aggregated retention system on taxonomic and functional diversity in a regenerating aspen-dominated forest. Sampling was conducted along transects arranged to capture the transition from harvested ...
Are We Producing Society-Ready Foresters? A Quantitative Content Analysis Of Graduate-Level Forestry Curriculum, 2020 University of Central Florida
Are We Producing Society-Ready Foresters? A Quantitative Content Analysis Of Graduate-Level Forestry Curriculum, Jacqueline Meyer
The Pegasus Review: UCF Undergraduate Research Journal (URJ)
Forestry education in the United States has been hailed for its ability to provide students with the scientific and technical skills needed for a career in forestry as much as it has been criticized for ignoring social dimensions of the discipline. Its inability to adapt curriculum to the increasingly multidisciplinary nature of the forestry profession has led to stagnant or decreasing enrollment and lack of student diversity in recent years. While forestry education and curriculum has been thoroughly analyzed at the undergraduate level, no such analysis exists for graduate curriculum. This study analyzes the course content of 40 graduate-level forestry ...

It can be difficult to make and implement land management decisions that are informed by the best available science, satisfy different stakeholders, and are compliant with established policies and regulations. Local, state, and federal entities with the capacity to influence land management decisions, can benefit from an understanding of the shared needs of landowners and managers. This needs assessment reports on the shared information, funding, and research needs expressed by land managers and owners throughout Utah who make decisions about: (1) fire prevention and suppression; (2) livestock grazing; (3) fisheries; or (4) wildlife. The report provides a high-level assessment of ...
Coastal Taxodium Distichum Growth Responses To Marine Influences And Stand Density, 2020 Louisiana State University and Agricultural and Mechanical College
Coastal Taxodium Distichum Growth Responses To Marine Influences And Stand Density, Stephanie Moothart
LSU Master's Theses
Ecological processes controlling transition areas of coastal wetlands between marshes (not forested) and swamps (forested) are poorly understood, despite important ecosystem services provided and strong interest in managing for ecosystem structure and function. The objective of this work was to identify how soil chemistry and stand density control individual-tree growth of the important coastal species baldcypress (Taxodium distichum (L.) Rich.) and pondcypress (Taxodium distichum var. imbricarium (Nutt.) Croom) along a coastal salinity gradient. Tree cores, soil samples, and stand density measurements were collected for sixty cypress trees at the coastal Joyce Wildlife Management Area, Louisiana, which is a former forested ...
Flooding, Landslides, Wildfires, Air Pollution, And Income: Risk In California, 2020 Gettysburg College
Flooding, Landslides, Wildfires, Air Pollution, And Income: Risk In California, Brittany Bondi, Alyssa J. Kaewwilai
Gettysburg Social Sciences Review
California is infamously known for its likelihood of environmental hazards such as flooding, landslides, air pollution, and forest fires which can be attributed to the natural climate of the area as well as anthropologically influenced climate change. Air pollution also poses potential threats and dangers to the civilians of California as increasing populations and uses of fossil fuels continue to contribute to the growing issue of climate change. The goal of this study was to examine and analyze the geospatial trends environmental hazards in California such as landslides, air pollution, flooding, and forest fires. A weighted test, zone and slope ...
Influence Of Timber Harvesting Operations And Streamside Management Zone Effectiveness On Sediment Delivery To Headwater Streams In Appalachia, 2020 Coalition for the Poudre River Watershed
Influence Of Timber Harvesting Operations And Streamside Management Zone Effectiveness On Sediment Delivery To Headwater Streams In Appalachia, Daniel Bowker, Jeffrey W. Stringer, Christopher D. Barton
Forestry and Natural Resources Faculty Publications
Disturbances created by timber harvesting equipment and associated haul roads and skid trails can create overland sediment flows (sediment paths), especially in steeply sloping terrain, leading to stream sedimentation. This study investigated the effect of variables associated with GPS tracked harvest equipment movement, skid trail development and retirement, topography, and streamside management zone (SMZ) width and tree retention on sediment delivery to streams. While the intensity of harvest equipment traffic was not correlated with sediment path development, the presence and location of skid trails were. All of the sediment paths were found to originate at water control structures, influenced by ...
Hosting Flame Cap Biochar Kiln Workshops To Teach Hazardous Fuel Reduction, 2020 Utah State University
Hosting Flame Cap Biochar Kiln Workshops To Teach Hazardous Fuel Reduction, Darren Mcavoy, Michael R. Kuhns, Megan Dettenmaier, Lauren Nicole Dupéy
The combination of large volumes of woody fuel needing disposal after forestry activities and evolving regulatory restrictions makes traditional methods of pile burning increasingly difficult. Alternatively, using small kilns to pyrolyze these fuels on-site yields a potentially valuable product: biochar. In this article, we describe an educational program on the use of small kilns for fuel treatment and biochar production. Survey results from our series of demonstrations indicate that 69% of respondents added biochar to their soils and 100% of respondents increased their interest in biochar. Moreover, we reduced hazardous fuel in Utah by more than 20 semitruck loads by ...
Simulated Mine Land Reclamation Impact On Biomass Partitioning And Nutrient Contents In Loblolly Pine, 2020 Stephen F. Austin State University
Simulated Mine Land Reclamation Impact On Biomass Partitioning And Nutrient Contents In Loblolly Pine, Osarumen Egharevba
Electronic Theses and Dissertations
Forest productivity on reclaimed mine land is hindered by soil compaction. Different techniques have been used to alleviate the effect of compaction to various degrees of success. The Forestry Reclamation Approach (FRA) was developed in the Appalachians and has been used to improve forest productivity on reclaimed mines in this region. The FRA provides a step by step method designed to reduce compaction, control erosion, provide land stabilization and accelerate forest succession. This method had not been evaluated in the Gulf Coastal Plain, where the pan scraper reclamation method is commonly used. However, using pan scrapers increases mine soil compaction ...

The Relationship Between Forest Fires And Forest Dynamics In California’S North Coast Bioregion: How Altered Fire Regimes Have Affected The Vegetative Outcomes Of Oak Woodlands And Mixed Conifer Forests, Max Bencomo
Master's Projects and Capstones
Wildfire is a necessary part of ecosystem function in California, but fire suppression and the spread of invasive species have endangered many ecosystems. The North Coast bioregion of California has seen dramatic shifts in forest ecology and vegetative density, largely due to the disruption of historic fire regimes. Historic fire regimes were previously maintained through indigenous land management, but the arrival of European settlers in the 1850’s initiated the changes reflected in current fire regimes. Not only is the North Coast bioregion the hotbed of recent fire activity, it is experiencing decreased counts of heterogeneity within forests while also ...
A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, 2020 The University of San Francisco
A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle
Master's Projects and Capstones
Wildfires in the mixed conifer forests of California’s Sierra Nevada have been a common and natural disturbance for thousands of years, historically occurring every 3 to 30 years. The flora and fauna of the mixed conifer forest have evolved to depend on low to moderate severity wildfires for reproduction, foraging, and habitat. However, the Sierra Nevada has experienced dramatic environmental changes over the past ~150 years as a result of three main factors: wildfire suppression, climate change, and habitat loss. Because of the threat wildfires pose to human lives, property and timber harvest, they have been suppressed to an ...
