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 ...


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 ...


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 ...


Quantifying Early-Seral Forest Composition With Remote Sensing, Rayma a. Cooley, Peter T. Wolter, Brian R. Sturtevant 2016 United States Forest Service

Quantifying Early-Seral Forest Composition With Remote Sensing, Rayma A. Cooley, Peter T. Wolter, Brian R. Sturtevant

Peter Wolter

Spatially explicit modeling of recovering forest structure within two years following wildfire disturbance has not been attempted, yet such knowledge is critical for determining successional pathways. We used remote sensing and field data, along with digital climate and terrain data, to model and map early-seral aspen structure and vegetation species richness following wildfire. Richness was the strongest model (RMSE = 2.47 species, Adj. R2 = 0.60), followed by aspen stem diameter, basal area (BA), height, density, and percent cover (Adj. R2 range = 0.22 to 0.53). Effects of pre-fire aspen BA and fire severity on post-fire aspen structure and ...


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 ...


Assisted Tree Migration In North America: Policy Legacies, Enhanced Forest Policy Integration, And Climate Change Adaptation, Adam Wellstead, Michael Howlett 2016 Michigan Technological University

Assisted Tree Migration In North America: Policy Legacies, Enhanced Forest Policy Integration, And Climate Change Adaptation, Adam Wellstead, Michael Howlett

Adam Wellstead

The weight of much expert forest management opinion is that issues such as climate change can be effectively addressed only if forest policy-making moves from a purely sectoral focus and undergoes a shift to a more integrated multi-issue, multi-sector policy-making process. This is because credible adaptation policies in the sector require greatly enhanced multi-sectoral policy integration if they are to succeed. But this requirement may be beyond the capacity of many countries to deliver. This article explores the integration challenges faced by forest policy-making in Canada and the United States and uses the case of Assisted Tree Migration (ATM) to ...


Systems Thinking In The Forest Service: A Framework To Guide Practical Application For Social-Ecological Management In The Enterprise Program, Megan Kathleen Kmon 2016 Portland State University

Systems Thinking In The Forest Service: A Framework To Guide Practical Application For Social-Ecological Management In The Enterprise Program, Megan Kathleen Kmon

Dissertations and Theses

The U.S. Forest Service (USFS) Enterprise Program (EP), which provides fee-for-service consulting services to the USFS, is interested in integrating systems thinking into its service offerings. Despite there being several excellent sources on the range and diversity of systems thinking, no single framework exists that thoroughly yet concisely outlines what systems thinking is along with its deep history, theoretical tenets, and soft and hard approaches. This thesis is an attempt to create such a framework, aimed specifically at practical application in a land management agency, through literature synthesis injected with original analysis. The usefulness of the framework is then ...

Agenda: Flpma Turns 40, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

FLPMA Turns 40 (October 21)

The Bureau of Land Management (BLM) administers approximately 245 million acres of our public lands and yet, for most of our nation's history, these lands seemed largely destined to end up in private hands. Even when the Taylor Grazing Act of 1934 ushered in an important era of better managing public grazing districts and "promoting the highest use of the public lands," such use of our public lands still was plainly considered temporary, "pending its final disposal." It was not until 1976 with the passage of the Federal Land Policy and Management Act (FLPMA) that congress adopted a policy ...

The Effect Of Prescribed Fires On Vernal Herbs, Janis Lemaster 2016 Western Kentucky University

The Effect Of Prescribed Fires On Vernal Herbs, Janis Lemaster

Honors College Capstone Experience/Thesis Projects

The effects of fire on vernal herbs are little known. David Kem attempted to assess the influences of spring and winter prescribed fires on vernal herbs by collecting abundance data on three sets of research plots located at the WKU Green River Preserve in Hart County, KY, on April 9-10, 2010. On April 10 he conducted spring burns, and on February 22, 2011, he conducted winter burns. He then collected post-fire data on the abundance of the herbs on the 12-19 of March, 2011. He found little influence of fire on overall species richness and the density of common species ...


Long-Term Overstory Vegetation Responses To Prescribed Fire Management For Longleaf Pine At Big Thicket National Preserve, Deanna M. Boensch 2016 Stephen F Austin State University

Long-Term Overstory Vegetation Responses To Prescribed Fire Management For Longleaf Pine At Big Thicket National Preserve, Deanna M. Boensch

Student Publications

At the western edge of the longleaf pine (Pinus palustris) range, federal land managers have burned the forests of Big Thicket National Preserve to bring back the structure and diversity of the longleaf pine forest. In the early 1990’s, a four year study was conducted by Rice University, and the National Park Service continued monitoring the study’s fire ecology research plots. After two decades of data collection, ordination was applied to species abundance data to examine changes in vegetation communities from a variety of prescribed fire treatments and controls. The vegetation data was separated by size class to ...


Effects Of Fire On Soil Co₂ Efflux In A Mature Longleaf Pine Forest, Knox Lemee Flowers 2016 University of Southern Mississippi

Effects Of Fire On Soil Co₂ Efflux In A Mature Longleaf Pine Forest, Knox Lemee Flowers

Master's Theses

This study was conducted from 2012-2013 in a 96 year old longleaf pine at the Lake Thoreau Environmental Center located Lamar County, MS. Measurements of soil CO₂ efflux (i.e., soil respiration or SR) rates (µmol m-2 sec-1) were taken across 8 field plots (4 burned, 4 unburned) before and after a prescribed fire on that occurred in May, 2012. These measurements were taken over diurnal cycles using a LICOR LI-8100A automated soil gas flux system with long term chambers. SR rates and soil temperature measurements were collected during 3 sampling periods in 2012 and 1 sampling period ...

Evaluating The Myth Of Allelopathy In California Blue Gum Plantations, Kristen Marie Nelson 2016 California Polytechnic State University - San Luis Obispo

Evaluating The Myth Of Allelopathy In California Blue Gum Plantations, Kristen Marie Nelson

Master's Theses and Project Reports

It is widely accepted that allelopathy is not only significant, but more or less singular, in the inhibition of understory vegetation in California Eucalyptus globulus (blue gum) plantations. However, there is no published documentation of allelopathy by blue gums against California native species. Here, we present evidence that germination and early seedling growth of five California native species are not inhibited by chemical extracts of blue gum foliage, either at naturally-occurring or artificially concentrated levels. In the greenhouse, seeds were germinated in field-collected soil from mature blue gum plantations and the adjacent native, coastal scrub communities. In petri plates, seeds ...


The Mexican Water Forest: Benefits Of Using Remote Sensing Techniques To Assess Changes In Land Use And Land Cover, Maria F. Lopez Ornelas 2016 University of San Francisco

The Mexican Water Forest: Benefits Of Using Remote Sensing Techniques To Assess Changes In Land Use And Land Cover, Maria F. Lopez Ornelas

Master's Projects

In the past 30 years, anthropogenic activities like urbanization, agriculture, road fragmentation and deforestation have resulted in changes in the land use and land cover (LULC) in the Mexican Water Forest. Due to the important ecosystem services, and the natural resources this forest provides, in Mexico, it has become increasingly necessary to use new technologies and tools to support the planning, implementation and integration of forest management and conservation plans, as well as ecological and socioeconomic analysis of this ecosystem. Remote Sensing techniques and Geographic Information Systems (GIS) have been a true technological and methodological revolution in the acquisition, management ...


Fire And Fuels: Vegetation Change Over Time In The Zuni Mountains, New Mexico, Luke Wylie 2016 University of Southern Mississippi

Fire And Fuels: Vegetation Change Over Time In The Zuni Mountains, New Mexico, Luke Wylie

Master's Theses

The Zuni Mountains are a region that has been dramatically changed by human interference. Anthropogenically, fire suppression practices have allowed a buildup of fuels and caused a change in the fire-adapted ponderosa pine ecosystem such that the new ecosystem now incorporates many fire-intolerant species. As a result, the low-severity fires that the ecosystem once depended on to regenerate the forest are much reduced, and these low-severity fires are now replaced by crown-level infernos that threaten the forest and nearby towns. In order to combat these effects, land managers are implementing fuel reduction practices and are striving to better understand the ...


Determining The Pollination Mechanism Of A Problematic Invasive Species In The Gulf South: Triadica Sebifera, Jennifer Wester Clark 2016 University of New Orleans

Determining The Pollination Mechanism Of A Problematic Invasive Species In The Gulf South: Triadica Sebifera, Jennifer Wester Clark

University of New Orleans Theses and Dissertations

Understanding the ecology of invasive species is vital to curb the homogenizing of ecosystems, yet the pollination mechanisms of the Chinese tallow tree (Triadica sebifera) in its introduced habitat remain ambiguous. This study examines self-pollination, wind pollination, and flower-visiting insects of tallow in a bottomland hardwood forest and Longleaf pine savannah in the U.S. Gulf South. These data suggest that self-pollination and airborne pollination are possible, but likely rare occurrences, although the possibility of apoxisis was not investigated. Seed production in exclusion experiments was significantly less than in open-pollinated flowers, and wind dispersal of tallow pollen dropped to essentially ...
