The Economic Effects Of Large Wildfires, Cassandra Mosley Dr., Krista Gebert, Pamela Jakes Dr., Laura Leete Dr., Max Nielsen-Pincus Dr., Emily Jane Davis Dr., Autumn Ellison, Cody Evers, Branden Rishel, Shiloh Sundstrom
Joint Fire Science Program Research Project Reports
Large wildfires disrupt the lives of workers, families, and employers. However, fire suppression and recovery efforts may provide economic opportunities. Unlike with other natural hazards, there has been little research about how wildfires affect local economies. The purpose of this project was to analyze the effects of large wildfires on labor markets and examine how fire suppression spending may mediate these effects. Main findings from this research suggest that (1) in the short term, labor market impacts from large wildfires are positive during the course of a fire, (2) in the long-‐term, large wildfires lead to greater economic instability by …

Effectiveness And Longevity Of Fuel Treatments In Coniferous Forests Across California, Nicole M. Vaillant, Erin Noonan-Wright, Scott Dailey, Carol Ewell, Alicia Reiner
Joint Fire Science Program Research Project Reports
Longevity of fuel treatment effectiveness to alter potential fire behavior is a critical question for managers preparing plans for fuel hazard reduction, prescribed burning, fire management, forest thinning, and other land management activities. Results from this study will help to reduce uncertainty associated with plan prioritization and maintenance activities. From 2001 to 2006, permanent plots were established in areas planned for hazardous fuel reduction treatments across 14 National Forests in California. Treatments included prescribed fire and mechanical methods (i.e., thinning of various sizes and intensities followed by a surface fuel treatment). After treatment, plots were re-measured at various intervals up …

Joint Fire Science Program Research Project Reports
A key barrier to resolving uncertainty about the effects of fire on ecosystem C balance is the fact that fire effects on ecosystem C budgets are manifested over decadal time scales, meaning that we are largely forced to draw inferences using space-for-time substitution, or chronosequence, studies. Whereas chronosequences allow us to study processes occurring over long time scales, they are almost never re-sampled to verify the temporal trajectory of response variables, raising questions about the validity of chronosequence estimates of post-fire C dynamics. We re-sampled a well-studied fire chronosequence of jack pine (Pinus banksiana) forests in Michigan, providing a unique …

This project, a collaboration between Colorado State University (CSU), Carnegie Mellon University (CMU), the University of Washington (UW), and the National Park Service (NPS), investigated the atmospheric aging of biomass burning plumes in order to examine changes in both primary particle emissions and the production of additional, secondary organic aerosol (SOA). Included in the project were chamber studies to directly study smoke aging as well as analyses of ambient samples to look for evidence of smoke aging and SOA formation in the ambient atmosphere. CMU conducted smog chamber studies to investigate the atmospheric evolution of fine particle and organic aerosol …
Fire And Fish Dynamics In A Changing Climate: Broad- And Local-Scale Effects Of Fire-Induced Water Temperature Changes On Native And Nonnative Fish Communities, Michael K. Young, Lisa Eby, Lisa Holsinger, Daniel J. Isaak, Robert E. Keane
Fire And Fish Dynamics In A Changing Climate: Broad- And Local-Scale Effects Of Fire-Induced Water Temperature Changes On Native And Nonnative Fish Communities, Michael K. Young, Lisa Eby, Lisa Holsinger, Daniel J. Isaak, Robert E. Keane
Joint Fire Science Program Research Project Reports
Fire is a key natural disturbance that affects the distribution and abundance of native fishes in the Rocky Mountain West. In the absence of migratory individuals from undisturbed portions of a watershed, persistence of native fish populations depends on the conditions of the post-fire stream environment. Stream temperatures typically warm after fire, and remain elevated until riparian vegetation recovers. An additional threat to native species is that nonnative fishes have invaded many waters, and these species tolerate or prefer warmer water temperatures. Thus, forecasting the long-term effects of fire on native fish populations requires an understanding of fire dynamics (size, …
Fire Effects On Seed Banks And Vegetation In The Eastern Mojave Desert: Implications For Post-Fire Management, Matthew L. Brooks, Steven Ostoja, Robert Klinger
Fire Effects On Seed Banks And Vegetation In The Eastern Mojave Desert: Implications For Post-Fire Management, Matthew L. Brooks, Steven Ostoja, Robert Klinger
Joint Fire Science Program Research Project Reports
Area burned has increased during the past few decades in the Mojave Desert due in part to increased dominance of highly flammable invasive non-native annual grasses. Management responses such as post-fire seedings have been implemented during the first 3 post-fire years to suppress the growth of the invasive annual grasses, promote recovery of native species, and facilitate the restoration of plant species diversity and abundance. Although there is a fair amount of information available on the effects of fire on plant diversity, density, and cover, there is very little information available regarding effects on soil seed banks to help guide …

Fire Rehabilitation Effectiveness: A Chronosequence Approach For The Great Basin, David A. Pyke, David S. Pilliod, Jeanne C. Chambers, Matthew L. Brooks, James Grace
Joint Fire Science Program Research Project Reports
Federal land management agencies have invested heavily in seeding vegetation for emergency stabilization and rehabilitation (ES&R) of non-forested lands. ES&R projects are implemented to reduce post-fire dominance of non-native annual grasses, minimize probability of recurrent fire, quickly recover lost habitat for sensitive species, and ultimately result in plant communities with desirable characteristics including resistance to invasive species and resilience or ability to recover following disturbance. Land managers lack scientific evidence to verify whether seeding non-forested lands achieves their desired long-term ES&R objectives. The overall objective of our investigation is to determine if ES&R projects increase perennial plant cover, improve community …

We completed an investigation of the long term legacies of fuels treatments in longleaf pine sandhills at Eglin Air Force Base in the panhandle of Florida. From 1994-1999, The Nature Conservancy conducted a large-scale, long-term study at Eglin Air Force Base to compare the effectiveness of midstory reduction treatments, including herbicide, growing season fire, and mechanical clearing on the restoration of longleaf sandhill pine forests. The study plots have been monitored continuously since the completion of the original study and information still exists for all experimental sites, which have been burned as part of the prescribed fire program at Eglin …

We measured the impacts of prescribed fire and small clear-cut tree harvesting on carbon dynamics in a mixed-conifer forest in the central Sierra Nevada. Soil CO2 efflux, above ground tree biomass, annual tree radial growth, and ecosystem carbon stored as litter, fine root and in the mineral soil were measured in four treatment sites: an un-manipulated control, a prescribed fire site, and two harvested sites, in one of which the soil was mechanically ripped to reduce soil compaction, a common practice done on industrial forest lands in the Sierra Nevada. Biomass and radial tee growth was also measured in a …

Fuel Treatment Effectiveness In The United States, Mark A. Cochrane, Michael C. Wimberly, Jeffrey C. Eidenshink, Zhi-Liang Zhu, Don Ohlen, Mark Finney, Matt Reeves
Joint Fire Science Program Research Project Reports
The fire situation in the United States is well documented with a growing prevalence of larger and more intense fires that have increasingly severe consequences for affected ecosystems and human health and well being. Increasingly, fuels management has been put forth and implemented as part of an integral strategy for limiting extreme fire behavior, reducing the area affected by wildfire and minimizing the economic and ecological costs of fires. Communities and land management agencies are now treating millions of acres of wildland fuels annually and an ever-increasing number of wildfires are burning treated lands. Although the scientific premises of various …
Historic Fire Frequency In Mountain Big Sagebrush Communities Of The Eastern Great Basin And Colorado Plateau: A Comparison Of Estimates Based Upon Proxy Fire Scar Records And Predictions Derived From Post-Fire Succession Rates, Stanley G. Kitchen, Peter J. Weisberg
Historic Fire Frequency In Mountain Big Sagebrush Communities Of The Eastern Great Basin And Colorado Plateau: A Comparison Of Estimates Based Upon Proxy Fire Scar Records And Predictions Derived From Post-Fire Succession Rates, Stanley G. Kitchen, Peter J. Weisberg
Joint Fire Science Program Research Project Reports
Knowledge of past fire regimes associated with mountain big sagebrush-dominated landscapes is inadequate for scientifically-based land management that requires assessment of departures from historic conditions. Widely utilized estimates of fire frequency for sagebrush ecosystems are largely based upon few studies using fire-scarred proxy trees positioned at the forest/shrubland ecotone. These studies, all conducted in the northern half of the species distribution, generally fail to adequately address questions of fire behavior across the fuels threshold at the forest/woodland-shrubland ecotone. Alternatively, post-fire rates of succession have been used to suggest fire frequencies compatible with big sagebrush recovery. Minimum and maximum fire-free intervals …
Impacts Of Repeated Wildfire On Vegetation In The Southern Appalachian Mountains, Thomas A. Waldrop, Donald L. Hagan, Matthew Reilly
Impacts Of Repeated Wildfire On Vegetation In The Southern Appalachian Mountains, Thomas A. Waldrop, Donald L. Hagan, Matthew Reilly
Joint Fire Science Program Research Project Reports
The infrequent occurrence of large wildfires in the southern Appalachian Mountains over the last several decades has offered few opportunities to study the impacts of these types of disturbances. As a result, relatively little is known about how heterogeneity in topography, vegetation, and recent disturbance history interact to influence patterns of fire severity across the landscape. Since 2000, five separate wildfires burned a large portion of the area in, and surrounding the Linville Gorge Wilderness in western North Carolina, two burned the same area a second time. Burn severity and vegetative recovery were measured in 152 plots established in 1992 …
Factors Influencing The Establishment And Survival Of Native Hardwood Tree Seedlings Of The Kentucky Inner Bluegrass Blue Ash-Oak Savanna-Woodland, James D. Shaffer
Factors Influencing The Establishment And Survival Of Native Hardwood Tree Seedlings Of The Kentucky Inner Bluegrass Blue Ash-Oak Savanna-Woodland, James D. Shaffer
Theses and Dissertations--Biology
Historically, the Kentucky Inner Bluegrass blue ash-oak savanna-woodland was the primary ecosystem of the Inner Bluegrass Region (IBR) of Kentucky. After European settlement, the majority (>99%) of Bluegrass savanna was converted to agricultural and urban land uses. Currently remnant savanna tree species are failing to recruit. Therefore, a long-term restoration ecology project researching competition and disturbance on seedling establishment, survival, and growth has been established at Griffith Woods (the largest remaining savanna in Kentucky) in Harrison Co., KY. Fourteen native hardwood tree species (a total of 6,168 seedlings) have been experimentally planted. Light, soil, surrounding vegetation, and herbivory, factors …

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 …
