Consequences Of Alternative Response Strategies To Wildland Fires In The Northern Rockies And Southwest In 2007 And 2008., Carol Miller, Aldo Leopold
JFSP Research Project Reports
This project addressed JFSP project announcement FA-FRA09-001, and the task statement “Trade-off assessments of AMR decisions”. The project evaluated the consequences of alternative responses to 2007 and 2008 wildland fires in three wilderness areas. Specifically, it examined alternative initial response strategies and what could have happened if ignitions had been allowed to burn. Consequences were quantified in terms of area and type of area burned, days of fire activity, and impact on landscape scale fire risk. Situational factors were also examined for their influence on the response strategy and outcome. Simulations of three case study extended duration fires were also …

Decision-Support Tools For Conserving Greater Sage-Grouse During Fire And Fuels Management Projects In Pinyon And Juniper Woodlands, Erica Fleishman, Jeanne C. Chambers, David S. Dobkin, Brett G. Dickson
Decision-Support Tools For Conserving Greater Sage-Grouse During Fire And Fuels Management Projects In Pinyon And Juniper Woodlands, Erica Fleishman, Jeanne C. Chambers, David S. Dobkin, Brett G. Dickson
JFSP Research Project Reports
Prescribed fire and other fuels management treatments have been suggested as mechanisms to slow expansion of pinyon and juniper woodlands while minimizing potential expansion of cheatgrass (Bromus tectorum) and increasing habitat quality and quantity for Greater Sage- Grouse (Centrocercus urophasianus). These treatments also may reduce the probability of severe wildfires, which can have undesirable effects on social, economic, cultural, and ecological values. However, achieving long-term goals related to fire and fuels may conflict with short-term goals related to survival and viability of native species. Fire can fragment high-quality habitat for species associated with woodlands, including more than 20 native species …
Developing High Quality Syntheses: Guidelines For Syntheses That Meet Fire Managers’ Needs And Are Scientifically Defensible, Jane Kapler Smith
Developing High Quality Syntheses: Guidelines For Syntheses That Meet Fire Managers’ Needs And Are Scientifically Defensible, Jane Kapler Smith
JFSP Research Project Reports
What constitutes a high-quality synthesis for wildland managers? Syntheses are often requested by managers and many have been produced by scientists, but they may not always hit the mark. This project integrated guidelines from the literature with reflections from interviews with natural resource professionals (scientists, managers, and science delivery specialists) to develop guidelines for increasing the usefulness of syntheses for managers. Different kinds of syntheses serve different needs. Narrative syntheses are the most common form published for wildland managers. This format allows the author to include background information and incorporate detailed explanations and case studies. Peer-reviewed literature reviews and systematic …

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
JFSP 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 …

Does Season Of Burning Affect Fuel Dynamics In Southeastern Forests?, Clinton S. Wright, Robert E. Vilnanek, James B. Cronan, J. Kevin Hiers, Brett Williams, Eugene Watkins, Greg Titus, Jennifer Hinckley
JFSP Research Project Reports
Land managers in the southeastern United States (U.S.) have actively used prescribed fire, primarily in the winter or dormant season, as a tool to control the growth of understory vegetation since the middle of the last century. There is evidence, however, that burning during the growing season may have different, and in some cases more desirable effects on ecosystem processes, vegetation structure, vegetation composition and, by virtue of these factors, understory fuels and potential fire behavior. We conducted an experiment to document and test for potential differences in the rate of fuel re-growth and accumulation following prescribed fires during the …
Effectiveness And Longevity Of Fuel Treatments In Coniferous Forests Across California, Nicole M. Vaillant, Erin Noonan-Wright, Scott Dailey, Carol Ewell, Alicia Reiner
Effectiveness And Longevity Of Fuel Treatments In Coniferous Forests Across California, Nicole M. Vaillant, Erin Noonan-Wright, Scott Dailey, Carol Ewell, Alicia Reiner
JFSP 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 …

Development Of Modeling Tools For Predicting Smoke Dispersion From Low-Intensity Fires, Warren E. Heilman, Shiyuan Zhong, John L. Hom Dr., Joseph J. Charney
JFSP Research Project Reports
Of particular concern to fire and air-quality management communities throughout the U.S. are the behavior and air-quality impacts of low-intensity prescribed fires for fuels management. For example, smoke from prescribed fires, which often occur in wildland-urban interface (WUI) areas and in areas where forest vegetation has a significant impact on the local meteorology, can linger for relatively long periods of time and have an adverse effect on human health. Smoke from wildland fires can also reduce visibility over roads and highways in the vicinity of and downwind of these fires, reducing the safety of our transportation system. The planning for …
Effects Of Stand-Replacing Wildfire On Ecosystem Carbon Pools In Lake States Jack Pine Forests, David E. Rothstein, John Bradford, Richard Corner, Katherine Chumack, Michael Cook, Ehsan Razavy-Toosi
Effects Of Stand-Replacing Wildfire On Ecosystem Carbon Pools In Lake States Jack Pine Forests, David E. Rothstein, John Bradford, Richard Corner, Katherine Chumack, Michael Cook, Ehsan Razavy-Toosi
JFSP 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 …

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
JFSP 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
JFSP 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 …

JFSP Research Project Reports
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 …

Climate Change, Carbon Sequestration, And Wildfire Management In Sierran Mixed Conifer Forests, Scott Stephens Dr., Brandon M. Collins, Sabina Dore, Danny L. Fry, Anna Wong
JFSP Research Project Reports
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 …

Fire Rehabilitation Effectiveness: A Chronosequence Approach For The Great Basin, David A. Pyke, David S. Pilliod, Jeanne C. Chambers, Matthew L. Brooks, James Grace
JFSP 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 …

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
JFSP 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
JFSP 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 …

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
JFSP 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 …
Agroforestry And Smallholder Farmers: Climate Change Adaptation Through Sustainable Land Use, Colin Mccabe
Agroforestry And Smallholder Farmers: Climate Change Adaptation Through Sustainable Land Use, Colin Mccabe
Capstone Collection
Agriculture in the developing world will be extremely hard hit by climate change, and smallholder farmers in Least Developed Countries (LDCs) are among the most vulnerable to its impacts. There is a range of agricultural adaptations to climate change, and each context demands a unique appraisal of impacts and adaptations based on specific geography, local climate variability and expected change, and social conditions. The term “climate-smart agriculture” (CSA) has come to embody a set of practices in crop and livestock cultivation that 1) reduce greenhouse gas emissions (climate change mitigation), 2) build resilience to the impacts of climate change for …

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
JFSP 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, …
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
JFSP 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 …

Using Escaped Prescribed Fire Reviews To Improve Organizational Learning, Anne E. Black Dr., James Saveland Dr., Dave Thomas, Jennifer Ziegler Dr.
JFSP 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 …

JFSP 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 …
