Evaluating The Current Status Of Chestnut-Present Forest Systems: Integrating Gigapan As A Tool For Site Assessment, Charles Taylor Brewer
Evaluating The Current Status Of Chestnut-Present Forest Systems: Integrating Gigapan As A Tool For Site Assessment, Charles Taylor Brewer
Theses, Dissertations and Capstones
The field of environmental science can directly benefit from a society driven by advances in technology. The loss of the American chestnut (Castanea denata) has had a significant negative environmental and economic impact throughout the Appalachian region. However, using an integrated approach utilizing recent advances in science and technology, we may be able to promote the re-introduction of a very similar species within this region. Using GigaPan as a tool for site assessment and data storage, and previous methods of biological field surveying within the critical detritus layer of the forest floor, we will assess the status of forest ecosystems …
The Detection Of Forest Structures In The Monongahela National Forest Using Lidar, Dominique Norman
The Detection Of Forest Structures In The Monongahela National Forest Using Lidar, Dominique Norman
Theses, Dissertations and Capstones
The mapping of structural elements of a forest is important for forestry management to provide a baseline for old and new-growth trees while providing height strata for a stand. These activities are important for the overall monitoring process which aids in the understanding of anthropogenic and natural disturbances. Height information recorded for each discrete point is key for the creation of canopy height, canopy surface, and canopy cover models. The aim of this study is to assess if LiDAR can be used to determine forest structures. Small footprint, leaf-off LiDAR data were obtained for the Monongahela National Forest, West Virginia. …
Predicting Dry Lightning Risk Nationwide, Joy Drohan
Predicting Dry Lightning Risk Nationwide, Joy Drohan
Joint Fire Science Program Briefs (2007-2012)
Meteorologists developed two formulas to predict the probability of dry lightning throughout the continental United States and Alaska and parts of Canada. Predictions are made daily and are accessible through the web at http://www.airfire.org/tools/daily-fire-weather/dry-lightning-probability. The emphasis is on the western United States, where dry lightning is a more common occurrence. Predictions are based on identifying days on which lightning is expected and separately determining whether there is likely to be at least 1/10th inch of accompanying rain. The formulas are run with the latest North American or Alaskan weather forecasting model and forecast dry lightning probabilities for about three days …

A Comprehensive Guide To Fuel Management Practices For Dry Mixed Conifer Forests In The Northwestern United States, Theresa B. Jain, Mike A. Battaglia, Han-Sup Han, Russell T. Graham, Christopher R. Keyes, Jeremy S. Fried, Johnathan E. Sandquist
Joint Fire Science Program Synthesis Reports
This guide describes the benefits, opportunities, and trade-offs concerning fuel treatments in the dry mixed conifer forests of northern California and the Klamath Mountains, Pacific Northwest Interior, northern and central Rocky Mountains, and Utah. Multiple interacting disturbances and diverse physical settings have created a forest mosaic with historically low- to mixed-severity fire regimes. Analysis of forest inventory data found nearly 80 percent of these forests rate hazardous by at least one measure and 20 to 30 percent rate hazardous by multiple measures. Modeled mechanical treatments designed to mimic what is typically implemented, such as thinning, are effective on less than …

Joint Fire Science Program Synthesis Reports
Fire will play an important role in shaping forest and stream ecosystems as the climate changes. Historic observations show increased dryness accompanying more widespread fire and forest die-off. These events punctuate gradual changes to ecosystems and sometimes generate stepwise changes in ecosystems. Climate vulnerability assessments need to account for fire in their calculus. The biophysical template of forest and stream ecosystems determines much of their response to fire. This report describes the framework of how fire and climate change work together to affect forest and fish communities. Learning how to adapt will come from testing, probing, and pushing that framework …

Social Science At The Wildland-Urban Interface: A Compendium Of Research Results To Create Fire-Adapted Communities, Eric Toman, Melanie Stidham, Sarah Mccaffrey, Bruce Shindler
Joint Fire Science Program Synthesis Reports
Over the past decade, a growing body of research has been conducted on the human dimensions of wildland fire. Building on a relatively small number of foundational studies, this research now addresses a wide range of topics including mitigation activities on private lands, fuels reduction treatments on public land, community impacts and resident behaviors during fire, acceptance of approaches to postfire restoration and recovery, and fire management policy and decisionmaking. As this research has matured, there has been a recognition of the need to examine the full body of resulting literature to synthesize disparate findings and identify lessons learned across …

Climate Change On The Shoshone National Forest, Wyoming: A Synthesis Of Past Climate, Climate Projections, And Ecosystem Implications, Janine Rice, Andrew Tredennick, Linda A. Joyce
United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications
The Shoshone National Forest (Shoshone) covers 2.4 million acres of mountainous topography in northwest Wyoming and is a vital ecosystem that provides clean water, wildlife habitat, timber, grazing, recreational opportunities, and aesthetic value. The Shoshone has experienced and adapted to changes in climate for many millennia, and is currently experiencing a warming trend that is expected to accelerate in the next century. Climate change directly and indirectly affects the Shoshone’s high-elevation, mountainous terrain that supports unique and sometimes rare ecological components. Several vulnerable and very responsive resources and processes on the Shoshone could interact to produce unforeseeable or undesirable ecosystem …

Phenology, by controlling the seasonal activity of vegetation on the land surface, plays a fundamental role in regulating photosynthesis and other ecosystem processes, as well as competitive interactions and feedbacks to the climate system. We conducted an analysis to evaluate the representation of phenology, and the associated seasonality of ecosystem- scale CO2 exchange, in 14 models participating in the North American Carbon Program Site Synthesis. Model predictions were evaluated using long-term measurements (emphasizing the period 2000–2006) from 10 forested sites within the AmeriFlux and Fluxnet-Canada networks. In deciduous forests, almost all models consistently predicted that the growing season started …

Fire And The Invasive Annual Grass Microstegium Vimineum In Eastern Deciduous Forests, S. Luke Flory, Keith Clay, Sarah Emery, Joseph Robb
Joint Fire Science Program Research Project Reports
Non-native plant invasions have the potential to change natural and prescribed fire regimes by increasing fuel loads, continuity of fuels, and fuel composition, which may alter fire intensity, damage native species, and promote further invasions. In this project we sought to evaluate the interaction between fire and the invasive annual grass Microstegium vimineum in eastern deciduous forests. Our goal was to determine if invasions enhance fire intensity, including fire temperatures, flame heights, and fire duration, and negatively affect tree regeneration, and stimulate further invasions. We also sought to determine how prescribed fires and the timing of fires affect the density …

Wildland Fire Suppression And Land Development In The Wildland/Urban Interface, Sheila Olmstead, Carolyn Kousky, Roger Sedjo
Wildland Fire Suppression And Land Development In The Wildland/Urban Interface, Sheila Olmstead, Carolyn Kousky, Roger Sedjo
Joint Fire Science Program Research Project Reports
This project has explored the hypothesis that public fire suppression in fire‐prone areas acts as a subsidy to landowners, incentivizing conversion of land to residential and commercial development. Landowners do not bear the full cost of their choice to build on land in fire‐prone areas, since they do not pay for suppression, though they reap all of the benefits, potentially resulting in economically inefficient levels of development. To test this hypothesis, we performed an econometric analysis of U.S. land use change between 1970 and 2000. Statistically, we identified the impacts of changes in fire suppression policy by exploiting a natural …

To Burn Or Not To Burn Oriental Bittersweet: A Fire Manager’S Conundrum, Noel B. Pavlovic, Stacey A. Leicht-Young, Ralph Grundel, Scott A. Weyenberg, Neal Mulconrey
Joint Fire Science Program Research Project Reports
Oriental bittersweet (Celastrus orbiculatus) is an introduced liana (woody vine) that has invaded much of the Eastern United States and is expanding west into the Great Plains. In forests, it can girdle and damage canopy trees. At Indiana Dunes, we have discovered that it is invading non-forested dune habitats as well. Anecdotal evidence suggests that fire might facilitate its spread, but the relationship between fire and this aggressive invader is poorly understood. We investigated four areas important to fire management of oriental bittersweet, each of which we will briefly summarize here. 1) What fire temperatures cause seed mortality? For seeds, …

Using Escaped Prescribed Fire Reviews To Improve Organizational Learning, Anne E. Black Dr., James Saveland Dr., Dave Thomas, Jennifer Ziegler Dr.
Joint Fire Science Program Research Project Reports
The US wildland fire community has been interested in cultivating organizational learning to improve safety and overall performance for a number of years. A key focus has been on understanding the difference between culpability (to be guilty) and accountability (to explain) and on re-orienting review processes towards building a collective account of (as opposed to finding individual blame for) unwanted outcomes. A variety of innovative methodologies have been developed, yet until this project, there has been no systematic reflection to determine whether or how any of the existing review processes might be assisting organizational learning. Through a series of five …

Joint Fire Science Program Research Project Reports
Historically, wildfire was an important agent of change in landscapes across the western United States. Fires of varying magnitudes and extents contributed to a mosaic of dynamic landscape conditions. For the past century, fire management that focuses on fire suppression has effectively altered the composition of many vegetation communities across the landscape. Fire management and other landuse practices associated with natural resource use, agriculture, and residential development have changed the complexity of terrestrial landscapes. Aquatic systems have not been exempt from these changes: alterations in disturbance processes on the landscape have changed inputs into the stream environment, and practices such …

Affecting Risk: Improving Hazard Communication In The Wildland-Urban Interface, Melissa Wright Dr., Destiny Aman
Joint Fire Science Program Research Project Reports
Wildfire hazard is a growing problem in many areas of the United States, especially in the wildland-urban interface (WUI), where homes and other structures border or intermingle with forests, shrubs and grasslands. Despite years of educational outreach by fire management officials promoting effective and affordable mitigation strategies, research shows that residents, especially seasonal residents and those new to an area, still tend to under-invest in mitigation, even when they perceive their risk to be high. Meanwhile, the social and economic costs of wildfire have increased with fire size and intensity and far exceed the costs of mitigation. This problem has …

Joint Fire Science Program Research Project Reports
In 2006 the Santa Ana wind-driven Esperanza fire burned through the North Mountain Experimental Area (NMEA) and vicinity, including the scars of 10 previous fires. Multiple images of the fire’s progression were taken using PSW Research Station’s airborne FireMapper thermal-imaging system. Existing fuels data and historic NMEA maps plus new fire images were used to investigate relationships between vegetation history, fire behavior and severity, and fuel consumption. Soil samples were collected at a subset of fire severity sample points to assess seed bank survival. Coordinated documentation of vegetation recovery addressed the effects of age class and fire severity on chaparral …

Assessing Fuels Treatments In Southern California National Forests In The Context Of Climate Change, Timothy J. Brown, Crystal A. Kolden, John T. Abatzoglou
Joint Fire Science Program Research Project Reports
One of the key uncertainties in fuels treatments is their longevity under a changing climate. Several recent studies have assessed fuel treatment effectiveness during historic fires, and in many cases found the treatment less effective than desired, particularly during extreme or record conditions. In 2007, southern California experienced one of the most severe fire seasons to-date due to record low fuel moistures early in the fire season (a key driver of the two-month long Zaca fire) and historic Santa Ana winds late in the season (resulting in several large late October fires). Climate change projections for the region suggest that …
Can Climate Change Increase Fire Severity Independent Of Fire Intensity?, Phil Van Mantgem, Marybeth Keifer, Rob Klinger, Eric Knapp
Can Climate Change Increase Fire Severity Independent Of Fire Intensity?, Phil Van Mantgem, Marybeth Keifer, Rob Klinger, Eric Knapp
Joint Fire Science Program Research Project Reports
We tested the idea that climate may affect forest fire severity independent of fire intensity. Pervasive warming can lead to chronic stress on forest trees (McDowell et al. 2008; Raffa et al. 2008), resulting in higher sensitivity to fire-induced damage (van Mantgem et al. 2003). Thus, there may be ongoing increases in fire severity (the number of trees killed), even when there is no change in fire intensity (the amount of heat released during a fire). We examined this question at a subcontinental scale by synthesizing existing information from plot-based prescribed fire monitoring databases across the western United States of …

Joint Fire Science Program Research Project Reports
Managers, regulators, and others often need information on the emissions from wildland fire and their expected smoke impacts. In order to create this information, combinations of models are utilized. The modeling steps follow a logical progression from fire activity through to emissions and dispersion. In general, several models and/or datasets are available for each modeling step, resulting in a large number of combinations that can be created to produce fire emissions or smoke impacts. Researchers, managers, and policy makers need information on how different model choices affect the resulting output, and guidance on what choices to make in selecting the …

Joint Fire Science Program Research Project Reports
Many U.S. forests, especially those with historically short-interval, low- to moderate-severity fire regimes, are too dense and have excessive quantities of fuels. Widespread treatments are needed to restore ecological integrity and reduce the high risk of destructive, uncharacteristically severe fires in these forests. Among possible treatments, however, the appropriate balance among cuttings, mechanical fuel treatments, and prescribed fire is often unclear. For improved decisionmaking, resource managers need much better information about the consequences of alternative management practices involving fire and mechanicaVmanual "fire surrogates." Long-term, interdisciplinary research thus should be initiated to quantify the consequences and tradeoffs of alternative fire and …
