Shifting Environmental Controls On Ch4 Fluxes In A Sub-Boreal Peatland, Thomas G. Pypker, P. A. Moore, John A. Hribljan, Rodney Chimner
Michigan Tech Publications
We monitored CO2 and CH4 fluxes using eddy covariance from 19 May to 27 September 2011 in a poor fen located in northern Michigan. The objectives of this paper are to: (1) quantify the flux of CH4 from a sub-boreal peatland, and (2) determine which abiotic and biotic factors were the most correlated to the flux of CH4 over the measurement period. Net daily CH4 fluxes increased from 70 mg CH4 m−2 d−1 to 220 mg CH4 m−2 d−1 from mid May to mid July. After July, CH4 …
Assessing The Biodiversity And Susceptibility Of Trees In Maxwell Park To Future Invasive Tree Pest Outbreaks, Genevieve Alexander '14
Assessing The Biodiversity And Susceptibility Of Trees In Maxwell Park To Future Invasive Tree Pest Outbreaks, Genevieve Alexander '14
Outstanding Senior Seminar Papers
The purpose of this project was to assess tree susceptibility to invasive tree pest outbreaks in a Central-Illinois urban park. Tree biodiversity in Maxwell Park, located in the Town of Normal, Illinois, was evaluated assuming that the greater the tree biodiversity in a park, the more resilient the park would be to future invasive tree pest outbreaks. The Town of Normal Parks and Recreation Department served as the community partner for this project. By determining Maxwell Park’s current level of biodiversity, proposed new trees for future replacement plantings could be identified to help increase biodiversity and decrease the potential for …

Koziol, Michael Billmire, Robert Chris Owen, Jeffrey Johnson, Michele Ginsberg, Tatiana Loboda, Shiliang Wu
Michigan Tech Research Institute Publications
Background
A study of the impacts on respiratory health of the 2007 wildland fires in and around San Diego County, California is presented. This study helps to address the impact of fire emissions on human health by modeling the exposure potential of proximate populations to atmospheric particulate matter (PM) from vegetation fires. Currently, there is no standard methodology to model and forecast the potential respiratory health effects of PM plumes from wildland fires, and in part this is due to a lack of methodology for rigorously relating the two. The contribution in this research specifically targets that absence by modeling …
The Effects Of Large Wildfires On Employment And Wage Growth And Volatility In The Western United States, Max Nielsen-Pincus, Cassandra Moseley, Krista Gebert
The Effects Of Large Wildfires On Employment And Wage Growth And Volatility In The Western United States, Max Nielsen-Pincus, Cassandra Moseley, Krista Gebert
Environmental Science and Management Faculty Publications and Presentations
We examined the effect of large wildfires on economic growth and volatility in the western United States. We matched wildfire data with quarterly employment and earnings growth data to assess the specific effect of wildfire on employment and wage growth in western US counties. Wildfires generally tended to exhibit positive effects on employment and wage growth in the quarter(s) during which suppression efforts were active. However, this effect transitioned to increased economic volatility following a wildfire. The effect of wildfire also varied by the type of county in which wildfire occurred. The amount of suppression costs invested locally had the …

Understanding how climate change may influence forest carbon (C) budgets requires knowledge of forest growth relationships with regional climate, long-term forest succession, and past and future disturbances, such as wildfires and timber harvesting events. We used a landscape-scale model of forest succession, wildfire, and C dynamics (LANDIS-II) to evaluate the effects of a changing climate (A2 and B1 IPCC emissions; Geophysical Fluid Dynamics Laboratory General Circulation Models) on total forest C, tree species composition, and wildfire dynamics in the Lake Tahoe Basin, California, and Nevada. The independent effects of temperature and precipitation were assessed within and among climate models. Results …

Climate Change And Fire Management In The Mid-Atlantic Region, Kenneth L. Clark, Nicholas Skowronski, Heidi Renninger, Robert M. Scheller
Environmental Science and Management Faculty Publications and Presentations
In this review, we summarize the potential impacts of climate change on wildfire activity in the mid-Atlantic region, and then consider how the beneficial uses of prescribed fire could conflict with mitigation needs for climate change, focusing on patters of carbon (C) sequestration by forests in the region. We use a synthesis of field studies, eddy flux tower measurements, and simulation studies to evaluate how the use of prescibed fire affects short-and long-term forest C dynamics. Climate change may create weather conditions more conducive to wildfire activity, but successional changes in forest composition, altered gap dynamics, reduced understory and forest …
Las Raíces De La Deforestación En El Departamento Pando, Jeremy Levine-Drizin
Las Raíces De La Deforestación En El Departamento Pando, Jeremy Levine-Drizin
Independent Study Project (ISP) Collection
This research paper examines the phenomenon of the recent trend of deforestation in the Pando department in northwestern Bolivia. Historically, the economy of Pando has always been based primarily in agro-forestal extraction activities that provided income to communities without the need to destroy the surrounding forests. The most important of these agro-forestal products have been rubber (primarily during the beginning of the 20th century) and more recently Castaña (Brazilian Nut). Recently however, as the result of various forces, the inhabitants of Pando have begun to cut down there forests at an alarming rate. The most relevant causes of this phenomenon …

Forestry and Natural Resources Faculty Publications
Understanding the temporal and spatial scale at which habitat alteration impacts populations is important for conservation and management. Amphibians have declined more than other vertebrates, and pond-breeding species are particularly susceptible to habitat loss and fragmentation because they have terrestrial and aquatic life stages. One approach to management of pond-breeding species is protection of core upland habitat surrounding the breeding pond. We used genetic variation as an indicator of population status in a common amphibian species, spotted salamanders (Ambystoma maculatum), to determine how amount of suitable upland habitat relates to population status in the greater Charlotte, North Carolina, …

Environmental Science and Management Faculty Publications and Presentations
The link between economic growth and natural hazards has long been studied to better understand the effects of natural hazards on local, regional, and country level growth patterns. However, relatively little generalizable research has focused on wildfires, one of the most common forest disturbances in the western United States (US). We examined the effect of large wildfires on employment growth across sectors and time in the western US.We matched wildfire occurrences from 2004 to 2008 and their duration with monthly employment data to identify the effect of wildfire on employment growth. Wildfires generally tended to exhibit positive effects on employment …
Dendrochronological Reconstruction Of Fire, Bogus Basin Area Boise National Forest, Amy L. Cutter
Dendrochronological Reconstruction Of Fire, Bogus Basin Area Boise National Forest, Amy L. Cutter
Student Research Initiative
Since people have settled along the Boise Front, there have been very few documented fire disturbances. This is likely an outcome of fire suppression policies. There is evidence, visible as scars on living trees, that the old growth ponderosa pines located on the East Side Trail in the Boise National Forest have withstood multiple fires. Samples were collected by using a chainsaw to remove small, partial cross-sections from several trees. The Boise Front master chronology was used to accurately cross-date the fire-scarred samples using COFECHA. Analysis of the samples revealed ten fire events ranging from 1709 to 1889. The fire …
Wildfire Assessment Using Farsite Fire Modeling: A Case Study In The Chihuahua Desert Of Mexico, John Brakeall
Wildfire Assessment Using Farsite Fire Modeling: A Case Study In The Chihuahua Desert Of Mexico, John Brakeall
FIU Electronic Theses and Dissertations
The Chihuahua desert is one of the most biologically diverse ecosystems in the world, but suffers serious degradation because of changes in fire regimes resulting in large catastrophic fires. My study was conducted in the Sierra La Mojonera (SLM) natural protected area in Mexico. The purpose of this study was to implement the use of FARSITE fire modeling as a fire management tool to develop an integrated fire management plan at SLM.
Firebreaks proved to detain 100% of wildfire outbreaks. The rosetophilous scrub experienced the fastest rate of fire spread and lowland creosote bush scrub experienced the slowest rate of …

An Integrated Research Approach To The Development Of Fungal Isolates As Bioherbicides For The Control Of Woody Weeds, Patrick Mershon
Independent Study Project (ISP) Collection
Prickly acacia (Acacia nilotica) is an invasive weed tree in Australia, ranked seventh on the list of Weeds of National Significance because of its aggressiveness and its economic and environmental impacts. The significant downsides to manual and chemical control of this species drove the search for a biological control mechanism. Surveying and sampling stands of A. nilotica naturally exhibiting disease symptoms yielded several native Australian fungi capable of pathogenesis in this species, which are currently under assessment as potential bioherbicides for this weed. Three field trials were established at the same site in order to further advance current …

Independent Study Project (ISP) Collection
La cuestión del calentamiento de la atmósfera causa de la pérdida del carbono de la biomasa está una preocupación a nivel mundial. Con la emisión de CO2 por la combustión de los combustibles fósiles, la temperatura ha subido aproximadamente 0.16 °C desde 1990 hasta 2000. El bosque, por otra parte, sirve como un tranque y el regulador de carbono mediante el intercambio de carbono entre la atmósfera y biosfera. Sin embargo, varios usos antropogénicos del bosque ha causado la desaparición de árboles y la gran pérdida de carbono de la biomasa global. Para medir la pérdida de carbono causada por …

Earth Systems Research Center
Nitrogen (N) and phosphorus (P) are tightly cycled in most terrestrial ecosystems, with plant uptake more than 10 times higher than the rate of supply from deposition and weathering. This near-total dependence on recycled nutrients and the stoichiometric constraints on resource use by plants and microbes mean that the two cycles have to be synchronized such that the ratio of N:P in plant uptake, litterfall, and net mineralization are nearly the same. Disturbance can disrupt this synchronization if there is a disproportionate loss of one nutrient relative to the other. We model the resynchronization of N and P cycles following …
“Hariyo Ban Nepalko Dhan” (“Nepal’S Wealth Is The Green Forest”): The People’S Participation In Structuring Sustainable Development Through Community Forestry, Natasha Eulberg
Independent Study Project (ISP) Collection
Community forestry has a long history in Nepal, and despite the nationalization of the country’s forests in the mid-twentieth century, current legislation determines that rights and execution of community forest management lies largely with community forest user groups (CFUGs). This research questions to what extent CFUGs truly represent autonomous bodies with the full power and ability to manage and utilize community forests and forest resources. This research also seeks to determine the impact and distribution of CFUG operations and benefits on CFUG members, and the ways in which CFUG management practices have impacted how group members perceive and interact with …

Wood Microsites At Timberline-Alpine Meadow Borders: Implications For Conifer Seedling Regeneration And Alpine Meadow Conifer Invasion, Adelaide C. Johnson, J. Alan Yeakley
Wood Microsites At Timberline-Alpine Meadow Borders: Implications For Conifer Seedling Regeneration And Alpine Meadow Conifer Invasion, Adelaide C. Johnson, J. Alan Yeakley
Environmental Science and Management Faculty Publications and Presentations
The importance of climate warming on forests is recognized worldwide and has increased attention on the significance of both timberline advance and alpine meadow invasion by forests. Successful seedling regeneration in alpine meadows depends on availability of suitable substrates, or microsites, for seedling establishment. We sought to determine whether wood microsites (i.e., nurse logs), which are regeneration sites in Pacific Northwest subalpine forests, promoted regeneration at timberline-alpine meadow borders. To determine the ecological role of wood microsites, we examined mechanisms forming wood microsites; compared density, survival, and percent nitrogen content of seedlings growing on wood microsites to adjacent soil substrates; …
Resin Volatiles Of Eastern Hemlock Induced By Its Non-Native Herbivores, Joshua D. Pezet
Resin Volatiles Of Eastern Hemlock Induced By Its Non-Native Herbivores, Joshua D. Pezet
Masters Theses 1911 - February 2014
Eastern hemlock (Tsuga canadensis) is in decline because of infestation by the invasive hemlock woolly adelgid (Adelges tsugae; ‘HWA’) and, to a lesser extent, the elongate hemlock scale (Fiorinia externa; ‘EHS’). Many conifers respond to insect herbivory by inducing oleoresin-based defenses, however it is unknown whether eastern hemlock is capable of this inducible response. We conducted a plantation setting study of artificially infested saplings to determine if feeding by HWA or EHS induces changes in the tree’s volatile chemistry. The induced changes in volatiles we found were unlike the terpenoid-based defenses of related conifers. Only HWA feeding …
Agent-Based Modeling Of Harvest Decisions By Small Scale Forest Landowners In Maine, Usa, Jessica Leahy, Erika Reeves, Kathleen Bell, Crista L. Straub, Jeremy Wilson
Agent-Based Modeling Of Harvest Decisions By Small Scale Forest Landowners In Maine, Usa, Jessica Leahy, Erika Reeves, Kathleen Bell, Crista L. Straub, Jeremy Wilson
Publications
Small-scale forests are an excellent example of coupled social-ecological systems, which involve human and biophysical subsystems with complex two-way feedback interactions. The multifaceted nature of landowner decisions drives a significant need to better understand decision-making processes, reactions to policy, and combined impacts on ecosystems in a comprehensive manner. Small-scale forests require an integrated approach to modeling the social and biophysical components comprehensively. Agent-based modeling involves modeling individualistic behavior and interpreting patterns that emerge. The interaction between agents and their environments makes this a valuable tool to assess repeated decisions of individual landowners responding to changing environmental conditions. Agent-based models can …
Public Procurement And Private Certification: The Case Of The Uk Tpp, Alex Latu
Public Procurement And Private Certification: The Case Of The Uk Tpp, Alex Latu
Transnational Business Governance Interactions Working Papers
Forestry certification schemes have been considered the paradigmatic instance of a new form of private governance that may challenge state-centered authority and public policy-making. Although governments and intergovernmental organizations are certainly not the schemes' "main architects", they are more involved in the overall effects of forestry certification than is often emphasized, notably through procurement policies. This paper examines a particularly interaction of private and public governance organizations, in the realm of forestry certification, among the UK government's Timber Procurement Policy (TPP), a governmental demand-side policy tool, and two major certification schemes — the Forest Stewardship Council (FSC) and the Program …
Uncertainty Associated With Estimating A Short-Term (1–3 Hr) Particulate Matter Concentration From A Human-Sighted Visual Range, William C. Malm, Bret A. Schichtel
Uncertainty Associated With Estimating A Short-Term (1–3 Hr) Particulate Matter Concentration From A Human-Sighted Visual Range, William C. Malm, Bret A. Schichtel
JFSP Research Project Reports
Several state air quality agencies have developed policies to issue air quality health index (AQI) warnings based on low values of visual range (Vr). Vr has been defined in the context of how far away a black object has to be such that it is just noticeable or visible. This distance at which a landscape feature can just be detected is referred to as the Vr. AQI warnings are based on the levels of particulates (PM2.5) resulting from fire smoke, often with less than 24-hr average concentrations. Because monitoring data are not available in …

JFSP Research Project Reports
Accurate, consistent, and timely fire severity maps are needed in all phases of fire management including planning, managing, and rehabilitating wildfires. The problem is that fire severity maps are commonly developed from satellite imagery that is difficult to use for planning wildfire responses before a fire has actually happened and can’t be used for real-time wildfire management because of the timing of the imagery delivery. Moreover, imagery is difficult to use for controlled fires such as prescribed burning. This study, called FIRESEV (FIRE SEVerity Mapping Tools) created a comprehensive set of tools and protocols to deliver, create, and evaluate fire …

Bark Beetles, Fuels And Future Fire Hazard In Contrasting Conifer Forests Of Greater Yellowstone, Monica G. Turner, William H. Romme, Philip A. Townsend, Roy A. Renkin, Daniel C. Donato, Martin Simard, Brian J. Harvey, Jacob M. Griffin
JFSP Research Project Reports
The extent and severity of bark beetle (Curculionidae: Scolytinae) epidemics and the frequency of large, severe fires have reached unprecedented levels in recent decades, and these trends are expected to continue with ongoing climate change. Insects and fire have tremendous ecological and economic effects in western forests, yet their interactions are poorly understood. We combined field studies and simulation modeling to understand how bark beetle infestation and post-outbreak management affect fire hazard in two widespread but contrasting forest types, lodgepole pine (Pinus contorta) and Douglas-fir (Pseudotsuga menziesii) in the Greater Yellowstone Ecosystem (GYE) in northwestern Wyoming. We directly addressed key …

Characterization Of Masticated Fuelbeds And Fuel Treatment Effectiveness In Southeastern Us Pine Ecosystems., L N. Kobziar, Alan J. Long, Wayne C. Zipperer, Jesse K. Kreye
JFSP Research Project Reports
Mechanical fuels treatments are being widely used in fire prone ecosystems where fuel loading poses a hazard, yet little research examining fuel dynamics, fire behavior, and ecological effects exists, especially in the southeastern US. In order to broaden our understanding of these treatments, effects of mechanical mastication ("mowing") were examined in a common pine ecosystem of the southeastern US Coastal Plain, where the post-mastication fuel environment is unique among ecosystems where mastication is being employed. Foliar litter dominates surface fuels after understory mastication in palmetto/gallberry pine flatwoods, however rapid recovery of shrubs quickly regains control over fire behavior. Treatments were …
