Herbivory Impacts On Growth And Survival Of Seedlings In Bottomland Hardwood Forest Restoration Sites In The Post Oak Savannah And Blackland Prairie Ecoregions Of Texas, Usa, Ryan J. Jacques 2017 Stephen F Austin State University

Herbivory Impacts On Growth And Survival Of Seedlings In Bottomland Hardwood Forest Restoration Sites In The Post Oak Savannah And Blackland Prairie Ecoregions Of Texas, Usa, Ryan J. Jacques

Electronic Theses and Dissertations

Interest in bottomland hardwood forests (BLHW) ecology and restoration has increased over the past 40 years. These communities aid in water quality improvement, streambank stabilization, and urban expansion mitigation. They also provide important habitat for many species of wildlife. Since the majority of remaining BLHW are degraded due to land fragmentation, restoration attempts are becoming commonplace within the Western Gulf Coastal Plain. However, restoration success has been mixed, with managers observing survival rates of <15% for desirable species due to various factors. Over two growing seasons, I investigated multiple factors that have potential to limit BLHW restoration success in East Texas. Specifically, I tested the impacts of herbivory by white-tailed deer (Odocoileus virginianus) and feral swine (Sus scrofa) on Nuttall oak (Quercus texana Buckley), Shumard oak (Q. shumardii Buckley), bur oak (Q. macrocarpa Michx.), and pecan (Carya ...

An Artificial Neural Network For Real-Time Hardwood Lumber Grading, Edward Thomas 2017 USDA Forest Service

An Artificial Neural Network For Real-Time Hardwood Lumber Grading, Edward Thomas

USDA Forest Service / UNL Faculty Publications

Computerized grading of hardwood lumber according to NHLA rules would permit fast assessment of sawn lumber and the evaluation of potential edging and trimming operations to improve lumber value. More importantly, to enable optimization of the hardwood lumber sawing process, a fast means of evaluating the potential value of boards before they are sawn is necessary. As log and lumber scanning systems become prevalent and common, these needs become more pressing. From an automation perspective, the NHLA lumber grades are difficult to implement efficiently in a computer program. Exhaustive approaches that examine every potential cutting size and combination to determine ...


Interactions Between White-Tailed Deer Density And The Composition Of Forest Understories In The Northern United States, Matthew B. Russell, Christopher W. Woodall, Kevin M. Potter, Brian F. Walters, Grant M. Domke, Christopher M. Oswalt 2017 University of Minnesota

Interactions Between White-Tailed Deer Density And The Composition Of Forest Understories In The Northern United States, Matthew B. Russell, Christopher W. Woodall, Kevin M. Potter, Brian F. Walters, Grant M. Domke, Christopher M. Oswalt

USDA Forest Service / UNL Faculty Publications

Forest understories across the northern United States (US) are a complex of tree seedlings, endemic forbs, herbs, shrubs, and introduced plant species within a forest structure defined by tree and forest floor attributes. The substantial increase in white-tailed deer (Odocoileus virginianus Zimmerman) populations over the past decades has resulted in heavy browse pressure in many of these forests. To gain an objective assessment of the role of deer in forested ecosystems, a region-wide forest inventory across the northern US was examined in concert with white-tailed deer density information compiled at broad scales. Results indicate that deer density may be an ...


Residential Building Energy Conservation And Avoided Power Plant Emissions By Urban And Community Trees In The United States, David J. Nowak, Nathaniel Appleton, Alexis Ellis, Eric Greenfield 2017 USDA Forest Service

Residential Building Energy Conservation And Avoided Power Plant Emissions By Urban And Community Trees In The United States, David J. Nowak, Nathaniel Appleton, Alexis Ellis, Eric Greenfield

USDA Forest Service / UNL Faculty Publications

Urban trees and forests alter building energy use and associated emissions from power plants by shading buildings, cooling air temperatures and altering wind speeds around buildings. Field data on urban trees were combined with local urban/community tree and land cover maps, modeling of tree effects on building energy use and pollutant emissions, and state energy and pollutant costs to estimate tree effects on building energy use and associated pollutant emissions at the state to national level in the conterminous United States. Results reveal that trees and forests in urban/community areas in the conterminous United States annually reduce electricity ...


Establishment Of American Chestnuts On Surface Mined Lands In Appalachian Coalfields Region, Michael E. French 2017 University of Kentucky

Establishment Of American Chestnuts On Surface Mined Lands In Appalachian Coalfields Region, Michael E. French

Theses and Dissertations--Forestry

American chestnut (Castanea dentata (Marsh.) Borkh.) was an dominant hardwood throughout eastern North America until the introduction of an exotic fungus (Cryphonectria parasitica (Murr.) Barr) in the early 20th century devastated American chestnut populations. Chestnuts that have been bred for blight resistance have recently become available for testing. Due to the overlap of American chestnut’s natural range and the Appalachian coalfields region, the potential establishment of founder populations of blight-resistant chestnuts on reclaimed coal surface mines has recently gained attention. This work examined chestnut establishment on a surface mine in eastern Kentucky to assess factors controlling early survival ...


Managing Upland Oak Forests With Disturbance And The Implications For Non-Native Species Invasions, Devin E. Black 2017 University of Kentucky

Managing Upland Oak Forests With Disturbance And The Implications For Non-Native Species Invasions, Devin E. Black

Theses and Dissertations--Forestry

Natural and anthropogenic disturbances have influenced forest stand structure and affected species compositions within forests for millennia. Disturbances such as fire, severe weather events, and forest management practices may result in significantly reduced tree biomass. Thus, these disturbances may lower canopy closure and stem density in support of forest management goals, such as open oak woodland restoration, or promote an increase in species richness within the forest understory. However, these types of disturbance may also produce the unwanted consequence of opening pathways for the invasion of non-native species. Once established, these non-native species may threaten native plant communities and biodiversity ...


Vegetation Response To Repeated Prescribed Burning And Varied Wildfire Severity In Upland Forests On The Cumberland Plateau, Kentucky, Zachary W. Poynter 2017 University of Kentucky

Vegetation Response To Repeated Prescribed Burning And Varied Wildfire Severity In Upland Forests On The Cumberland Plateau, Kentucky, Zachary W. Poynter

Theses and Dissertations--Forestry

As a result of decades of fire suppression, oaks (Quercus L.) and other disturbance-dependent tree species are experiencing widespread regeneration failure. Today, fire takes the form of relatively low to moderate intensity prescribed fire, used to restore fire adapted ecosystems, and wildfires which often vary in severity. I investigated long-term changes to forest structure and composition in response to repeated prescribed burning followed by an extended period of no fire. Burning reduced total basal area, midstory stem density and sapling stem density. However, the fire-free interval significantly increased sapling layer stem densities of oaks and competitor species. This research shows ...


Invasion Dynamics Of The Exotic Liana Euonymus Fortunei (Turcz.) Hand.-Mazz. (Wintercreeper), Todd J. Rounsaville 2017 University of Kentucky

Invasion Dynamics Of The Exotic Liana Euonymus Fortunei (Turcz.) Hand.-Mazz. (Wintercreeper), Todd J. Rounsaville

Theses and Dissertations--Biology

Elevated atmospheric CO2 has been implicated as a driver of increased liana abundance worldwide. Known as disturbance creators and beneficiaries, lianas possess the potential to significantly influence forest ecosystems. I investigated the early-invasion dynamics of Euonymus fortunei (wintercreeper), an evergreen liana that is invading forests in eastern North America, disrupting native plant communities and ecosystem functions.

Wintercreeper is widely cultivated as an ornamental groundcover, frequently invading natural areas via asexual stem growth. Invasion of remote natural areas is dependent upon seed transport and may occur less frequently. I examined the mechanisms of seed dormancy by conducting a ‘move-along’ experiment ...


Influence Of Prescribed Burning On Upland Soil Properties In Mark Twain National Forest, Southeast Missouri Ozarks, Megan Lynn Hente 2017 Missouri State University

Influence Of Prescribed Burning On Upland Soil Properties In Mark Twain National Forest, Southeast Missouri Ozarks, Megan Lynn Hente

MSU Graduate Theses

In the Mark Twain National forest there is a collaborative effort to restore parts of the forest to its original shortleaf pine-oak woodland areas by using a combination of silviculture and prescribed fire. The purpose of this project is to assess the effects of prescribed burning on upland forest and soil physical properties that influence erosion processes across a gradient of burned sites of different ages and unburned sites. A combination of geospatial, field, laboratory, statistical (one-way ANOVA) and modeling (USLE) methods were used to assess the effects of prescribed burns on forest and soil characteristics in Big Barren Creek ...


Assessing Growth, Yield, And Carbon Dynamics In Upper Great Lakes Jack Pine And Hybrid Poplar Managed For Biomass Production, Ashlee Baker Lehner 2017 Michigan Technological University

Assessing Growth, Yield, And Carbon Dynamics In Upper Great Lakes Jack Pine And Hybrid Poplar Managed For Biomass Production, Ashlee Baker Lehner

Dissertations, Master's Theses and Master's Reports

Woody biomass for use as coal-replacing bioenergy has garnered increasing interest as federal and local governments require larger portions of energy production to come from renewable sources. Woody biomass can be produced from dedicated plantations grown and harvested solely for biomass production, or non-dedicated sources such as harvest residues from traditional timber operations. The creation of site index curves for hybrid poplar were established from the Michigan Technological University Hybrid Poplar Network in the upper Great Lakes Region. These site index models are to be used for landowners to assess the predicted yield at established plantations, or possibly within spatial ...


Characterization Of Genic Microsatellite Markers (Est-Ssrs) In The Endangered Oak Species Quercus Georgiana M.A.Curtis, Priyanka Dipak Kadav 2017 Michigan Technological University

Characterization Of Genic Microsatellite Markers (Est-Ssrs) In The Endangered Oak Species Quercus Georgiana M.A.Curtis, Priyanka Dipak Kadav

Dissertations, Master's Theses and Master's Reports

Quercus is important ecologically and economically because it provides food and habitat for wildlife, wood and paper products for humans. Oaks are endangered due to various factors like shifting climates, habitat loss, drought, pathogens and genetic swamping. Quercus georgiana (M.A. Curtis) is an endangered and restricted oak species which is remaining only in the southeastern part of the US. Efforts are required to conserve this endangered species from extinction. Conservation of this species can be done through these methods: ex-situ conservation (arboretum and botanical garden) and in-situ conservation strategies which protect the species in its natural habitat. For this ...

Old-Growth Characteristics Of Northern White-Cedar Stands, Nathan Wesely 2016 University of Maine

Old-Growth Characteristics Of Northern White-Cedar Stands, Nathan Wesely

Electronic Theses and Dissertations

Northern white-cedar (Thuja occidentalis; hereafter white-cedar) communities have received relatively little research attention, and managers lack the tools used in the management of other commercial tree species. This includes the recognition of old-growth characteristics and the differentiation between old-growth and partially harvested stands, particularly in the context of Forest Stewardship Council (FSC-US) certification. Specifically, there is very little information about characteristics that define old-growth white-cedar stands despite the species’ abundance and wide distribution. Regional indices for late-successional or old-growth stands (Whitman and Hagan, 2007) do not include white-cedar. Forests dominated by white-cedar represent a type that currently lacks quantitative benchmarks ...


Modeling And Forecasting The Influence Of Current And Future Climate On Eastern North American Spruce-Fir (Picea-Abies) Forests, Caitlin Andrews 2016 The University of Maine

Modeling And Forecasting The Influence Of Current And Future Climate On Eastern North American Spruce-Fir (Picea-Abies) Forests, Caitlin Andrews

Electronic Theses and Dissertations

The spruce-fir (Picea-Abies) forest type of the Acadian Region is at risk of disappearing from the United States and parts of Canada due to climate change and associated impacts. Managing for the ecosystem services provided by this forest type requires accurate forecasting of forest metrics across this broad international region in the face of the expected redistribution of tree species. This analysis linked species specific data with climate and topographic variables using the nonparametric random forest algorithm, to generate models that accurately predicted changes in species distribution due to climate change. A comprehensive dataset, consisting of 10,493,619 observations ...


Determining Public Perceptions Toward Wildland Fire In The Veluwe Region Of The Netherlands, Amy Brennan 2016 Stephen F. Austin State University

Determining Public Perceptions Toward Wildland Fire In The Veluwe Region Of The Netherlands, Amy Brennan

Electronic Theses and Dissertations

The Netherlands has been facing a growing threat of wildfires due to warmer

and drier weather patterns. The purpose of this study was to identify public

perceptions toward wildland fire in the forested Veluwe region of the country. The

Dutch have little experience with wildland fires or fire as a management tool. In a

collaborative effort between Stephen F. Austin State University and the Instituut

Fysieke Veiligheid, the Dutch public safety agency, a survey was distributed to

residents and visitors to the Veluwe to reveal and quantify public opinions and

perceptions regarding wildland fire and public expectations of government

agencies ...


Effects Of Prescribed Fire On The Forest Structure And Composition At Land Between The Lakes National Recreation Area, Ky, Miranda Thompson 2016 Murray State University

Effects Of Prescribed Fire On The Forest Structure And Composition At Land Between The Lakes National Recreation Area, Ky, Miranda Thompson

Honors College Theses

With a regular fire regime present on the landscape, open canopies and herbaceous understories characterize oak forests in western Kentucky. However, a long period of fire suppression has changed the structure and composition of many forests in the Southeast. Forest managers at Land Between the Lakes have started using prescribed fire in an attempt to replicate aspects of a natural fire regime and increase the amount of open oak woodlands and savannas in the area. The prescribed fires in our study area were conducted during the dormant season and are very low intensity ground fires.

To understand how prescribed fire ...


Comparison Of Four Harvesting Systems In A Loblolly Pine Plantation, John Klepac, Dana Mitchell 2016 USDA Forest Service, Southern Research Station

Comparison Of Four Harvesting Systems In A Loblolly Pine Plantation, John Klepac, Dana Mitchell

Professional Agricultural Workers Journal

Abstract

Felling and skidding operations were monitored while clearcut harvesting a 12-acre area of a 14-year old loblolly pine (Pinus taeda) plantation. The study area contained 465 trees per acre for trees 2.0 inches Diameter at Breast Height (DBH) and larger with a Quadratic Mean Diameter (QMD) of 7.26 inches. Two feller-bunchers (tracked and rubber-tired) and two skidders (conventional and large capacity) were paired to create four different harvesting systems which were randomly assigned to 3-acre units for evaluation of production rates and costs. Each system was balanced to determine the number of machines needed to minimize the ...
