Synthesis Of Knowledge On The Effects Of Fire And Fire Surrogates On Wildlife In U.S. Dry Forests, Patricia L. Kennedy, Joseph B. Fontaine
Synthesis Of Knowledge On The Effects Of Fire And Fire Surrogates On Wildlife In U.S. Dry Forests, Patricia L. Kennedy, Joseph B. Fontaine
Joint Fire Science Program Research Project Reports
Dry forests throughout the United States are fire-dependent ecosystems, and much attention has been given to restoring their ecological function. As such, land managers often are tasked with reintroducing fire via prescribed fire, wildland fire use, and fire-surrogate treatments such as thinning and mastication. During planning, managers frequently are expected to anticipate effects of management actions on wildlife species. This document represents a synthesis of existing knowledge on wildlife responses to fire and fire-surrogate treatments, presented in a useful, management-relevant format. Based on scoping meetings and dialogue with public lands managers from throughout the United States, we provide detailed, species-level, …
Effects Of Prescribed Fire On Biological Soil Crusts And Their Subsequent Recovery In A Great Basin Juniper Woodland, Steven D. Warren, Larry L. St.Clair, Jeffrey R. Johansen, Paul Kugrens
Effects Of Prescribed Fire On Biological Soil Crusts And Their Subsequent Recovery In A Great Basin Juniper Woodland, Steven D. Warren, Larry L. St.Clair, Jeffrey R. Johansen, Paul Kugrens
Joint Fire Science Program Research Project Reports
A prescribed burn was conducted in a juniper woodland approximately 40 km south of Tooele, Utah on 05 October 2006. Conditions were sub-optimal, and the fire did not encroach into mid- or late-successional areas; only the early-successional area burned successfully. This study evaluated the effects of the prescribed burn on biological soil crusts that occupy the soil surface and are important for soil stability, soil nutrient cycling, and the germination and survival of vascular plants. Biological soil crusts are composed primarily of cyanobacteria, green algae, lichens and mosses. Mosses were rare under juniper trees, so the effects of the fire …
Effects Of Fuels/Fire Risk Reduction Treatments Using Hydro-Mow Or Thinning On Pinyon-Juniper Ecosystem Components Within The Wildland-Urbaninterface., Gerard J. Gottfried, Steven T. Overby, Philip A. Kemp, Cara Macmillan
Effects Of Fuels/Fire Risk Reduction Treatments Using Hydro-Mow Or Thinning On Pinyon-Juniper Ecosystem Components Within The Wildland-Urbaninterface., Gerard J. Gottfried, Steven T. Overby, Philip A. Kemp, Cara Macmillan
Joint Fire Science Program Research Project Reports
Pinyon-juniper woodlands are a dominant vegetation type throughout the Interior West on lands managed by the U.S. Forest Service and the USDI Bureau of Land Management. The woodlands have traditionally been viewed as having a low risk of wildfires because of the lack of a continuous and dense ground cover and low tree stand densities. However, stand densities are often high and are increasing in many areas and wildfires, often resulting in loss of lives and property, will occur under conditions of low humidity, high temperatures and wind speeds, and an ignition source. Woodlands commonly surround or are adjacent to …
Ecological Effects Of Prescribed Fire Season: A Literature Review And Synthesis For Managers, Eric Knapp, Becky Estes, Carl N. Skinner
Ecological Effects Of Prescribed Fire Season: A Literature Review And Synthesis For Managers, Eric Knapp, Becky Estes, Carl N. Skinner
Joint Fire Science Program Research Project Reports
Prescribed burning may be conducted at times of the year when fires were infrequent historically, leading to concerns about potential adverse effects on vegetation and wildlife. Historical and prescribed fire regimes for different regions in the continental United States were compared and literature on season of prescribed burning synthesized. In regions and vegetation types where considerable differences in fuel consumption exist among burning seasons, the effects of prescribed fire season appears, for many ecological variables, to be driven more by fire-intensity differences among seasons than by phenology or growth stage of organisms at the time of fire. Where fuel consumption …
Epidemic Southern Pine Beetle Attacks: A Problem Of Fuel-Loading Or An Opportunity For Management?, Thomas A. Waldrop, G. Geoffrey Wang, Knight Cox
Epidemic Southern Pine Beetle Attacks: A Problem Of Fuel-Loading Or An Opportunity For Management?, Thomas A. Waldrop, G. Geoffrey Wang, Knight Cox
Joint Fire Science Program Research Project Reports
The Piedmont Region of South Carolina experienced one of the heaviest attacks of southern pine beetle (Dendroctonus frontalis Zimm.) in history during the early part of this decade. Managers with both commercial objectives and restoration objectives needed information on how prescribed burning or mechanical treatments can be used to reduce the heavy fuels resulting from these attacks, without neglecting their primary management objectives. Prescribed burning is of concern because intensities are expected to be high and fires may damage soils, neighboring trees, or target vegetation. Methods of predicting fire behavior and fuel consumption are unavailable. Mechanical treatments will reduce fuels …
Estimating Canopy Fuels And Their Impact On Potential Fire Behavior For Ponderosa Pine In The Black Hills, South Dakota., Frederick W. Smith, Tara Keyser, Wayne Shepperd
Estimating Canopy Fuels And Their Impact On Potential Fire Behavior For Ponderosa Pine In The Black Hills, South Dakota., Frederick W. Smith, Tara Keyser, Wayne Shepperd
Joint Fire Science Program Research Project Reports
We evaluate whether current procedures used in fire behavior prediction models such as FVS-FFE provide predictions of CBD and CBH suitable for evaluating fire behavior in response to fuel treatments. Currently, FFE-FVS uses a geographic non-specific set of tree allometries and assumes a uniform distribution of crown mass when estimating CBH and CBD. We develop allometric equations to predict crown mass specific to ponderosa pine in the Black Hills (Pinus ponderosa Dougl. ex Laws.) from a sample of 80 felled trees in 16 forest stands spanning a wide range in tree size and stand. We develop a non-uniform description of …

Estimating The Biomass Of Hand-Piled Fuels For Smoke Management Planning, Clinton S. Wright, Robert E. Vilnanek, James Russell, Mark Middy, Jim Bailey, Steve Davis, Robert Sanders, Cameron Balog, Paige Eagle
Joint Fire Science Program Research Project Reports
Dimensions, volume, and biomass were measured for 121 hand-constructed piles composed primarily of coniferous (n=61) and shrub/hardwood (n=60) material at sites in Washington and California. Equations using pile dimensions, shape, and type allow users to accurately estimate the biomass of hand piles. Equations for estimating true pile volume from simple geometric shapes and measurements of pile dimensions were also developed to allow users who require estimates of pile volume for regulatory reporting. Biomass and volume estimation equations are being programmed into a web-based calculator to allow users to estimate either value from pile dimensions.
Reducing Fine Fuel Loads, Controlling Invasive Annual Grasses, And Manipulating Vegetation Composition In Zion Canyon, Utah, J. R. Matchett, Aviva O'Neill, Matt Brooks, Cheryl Decker, Jennifer Vollmer, Curt Deuser
Reducing Fine Fuel Loads, Controlling Invasive Annual Grasses, And Manipulating Vegetation Composition In Zion Canyon, Utah, J. R. Matchett, Aviva O'Neill, Matt Brooks, Cheryl Decker, Jennifer Vollmer, Curt Deuser
Joint Fire Science Program Research Project Reports
Fine fuels created by non-native annual grasses are a land management problem throughout the United States and beyond. These fuels facilitate the ignition of wildfires and promote their spread, creating hazardous fuel conditions in wildland urban interface areas. For example, fine fuel accumulations from non-native annual grasses in the riparian corridor at Zion National Park threaten the few egress routes from Zion Canyon, creating a threat to human life should a large wildfire occur there. In addition, when these non-native plants create novel fuel characteristics and fire behavior, they can lead to altered fire regimes that can significantly degrade natural …

Joint Fire Science Program Research Project Reports
This project addresses the need for a collaborative architecture for scientific modeling that allows various scientific models to easily interact. The need for such a system has been documented by recent studies such as the JFSP Smoke Roundtables and the JFSP review of tools done by the Software Engineering Institute. This project addresses these needs by modifying the BlueSky Modeling Framework so that it can better serve as a collaborative architecture, and then utilizing this architecture to create an advanced application that could not otherwise be created. The BlueSky framework was modified for this purpose, and all changes integrated into …

Joint Fire Science Program Research Project Reports
The Healthy Forest Restoration Act of 2003 (HFRA) was enacted to reduce wildfire risk to communities and other at-risk lands through a collaborative process of planning, prioritizing and implementing hazardous fuel reduction projects. One of the key features of HFRA is the development of community wildfire protection plans (CWPPs). We studied the development of CWPPs in order to identify those factors and processes that consistently lead to effective collaborative fire and fuels management as defined by HFRA, and enhance local social capacity to sustain wildfire protection activities into the future. Findings from this research highlight the importance of: (1) drawing …

Characterizing Particulate Matter Emissions By Wildland Fires Relevant To Visibility Impairment And Pm Non-Attainment, William Malm, Douglas Fox, Hans Moosmüller, Sonia Kreidenweis, Jeffrey Collett Jr., Wei Min Hao
Joint Fire Science Program Research Project Reports
Carbonaceous aerosols, which include contributions from industrial and mobile source emissions and biomass combustion, exert a significant impact on regional air quality. Some preliminary semi-quantitative analyses suggest that smoke from fire-related activity may contribute significantly to observed organic mass concentrations. Further, these emissions have resulted in increased conflicts with the need to attain air quality standards, especially for particulate matter (PM) and visibility, as mandated by the Clean Air Act. However, federal land managers and policy makers currently lack several important tools needed for air quality assessments: composition profiles and analytical techniques necessary to differentiate carbonaceous aerosols originating from industrial …

Joint Fire Science Program Research Project Reports
Today, park managers must routinely balance the restoration needs of natural resources with the preservation of cultural resources. This project was designed to provide park managers with scientific data on the impacts from wildland fire to archeological resources at National Park Service units in the Midwest Region. Experimental research was conducted at six parks to record data on fire conditions (i.e., fuels, fire temperature, and burn duration) and the impacts on multiple classes of archeological materials routinely observed at sites within the region. The experimental study of fire conditions in different regional environments addresses questions regarding the threats or non-threats …
A Regional Assessment Of The Ecological Effects Of Chipping And Mastication Fuels Reduction And Forest Restoration Treatments., Mike Battaglia, Charles Rhoades, Monique E. Rocca, Michael G. Ryan
A Regional Assessment Of The Ecological Effects Of Chipping And Mastication Fuels Reduction And Forest Restoration Treatments., Mike Battaglia, Charles Rhoades, Monique E. Rocca, Michael G. Ryan
Joint Fire Science Program Research Project Reports
Over the past several years, fire managers have increased their use of mastication treatments, the on-site disposal of shrubs and small-diameter trees through chipping and shredding. Mastication is a relatively untested management practice that alters the chemical and physical conditions of the forest floor and may influence vegetation regrowth and fuel development for years or decades. Eighteen sites were established across four ecosystems of the southern Rocky Mountains and the Colorado Plateau: lodgepole pine (Pinus contorta), mixed conifer (Pinus ponderosa, Pseudotsuga menziesii, Pinus flexilis, and Pinus contorta), ponderosa pine (Pinus ponderosa), and pinyon pine/juniper …

Fire And Fuels Management In Coast Redwood Forests, Steven P. Norman, J. Morgan Varner, Leonel Arguello, Stephen Underwood, Bradley Graham, Greg Jennings, Yana Valachovic, Christopher Lee
Joint Fire Science Program Research Project Reports
Coast redwood forests rank among the most significant natural features of North America, yet our understanding of how they came to be and how we might sustain them has been beset by scientific and management uncertainty for decades. A key part of this controversy has been the historical importance of fire given the mild coastal climate and small number of lightning ignitions. In the northern part of the coast redwood range, past research found that fire was uncommon, but results conflicted with others that found fire to be as frequent as in any dry forest of western North America. We …

Joint Fire Science Program Research Project Reports
Department of the Interior (DOI) bureaus have invested heavily (for example, the U.S. Bureau of Land Management (BLM) spent more than $60 million in fiscal year 2007) in seeding vegetation for emergency stabilization and burned area rehabilitation of non-forested arid lands over the past 10 years. The primary objectives of these seedings commonly are to (1) reduce the post-fire dominance of non-native annual grasses, such as cheatgrass (Bromus tectorum) and red brome (Bromus rubens); (2) minimize the probability of recurrent fire; and (3) ultimately produce desirable vegetation characteristics (for example, ability to recover following disturbance [resilience], resistance to invasive species, …

Extending The Reach Of The Fire Effects Planning Framework By Taking A Critical Approach To Science Delivery And Application, Anne E. Black, Carol Miller, Vita Wright, Kate Walker, Carolyn Ballard, Paula Nasiatka, Brett Fay, Linda Chappell, Dave Calkin
Joint Fire Science Program Research Project Reports
The Fire Effects Planning Framework (FEPF), developed under JFSP project (99-1-3-16) “Wildland fuels management: evaluating and planning risks and benefits,” was formally completed in June 2004. FEPF is a logical framework that uses available data (e.g., local, LANDFIRE data) and existing software (e.g., GIS, Farsite, FlamMap, expert knowledge) to produce maps of probable fire effects during the pre-season or in advance of a fire front. The initial project included significant technology transfer activities. As that project concluded, however, we continued to receive requests for assistance from field managers (District, Forest and Regional Forest Service offices), international organizations (Interior West Fire …

A Synthesis Of Live Fuel Moisture And Wildland Fire And Development Of A National Historical Live Fuel Moisture Database, William M. Jolly Dr.
Joint Fire Science Program Research Project Reports
Live fuels are a key component to the wildland fuel complex but little is know about their contribution to fire danger or fire behavior. This review attempts to quantify our current understanding of the role that live fuels play in combustion and how those characteristics are quantified into prediction systems that fire managers use to assess fire danger or fire behavior as well as how live fuel parameters for those systems are measured. We review how live fuels are incorporated into three fire danger and fire behavior prediction systems that have found widespread use throughout the world. We discuss the …

This project delivers up-to-date, science-based information about species nominated by wildland managers for revision in or addition to the Fire Effects Information System (FEIS). FEIS now provides 1,081 literature reviews covering 1,139 taxa. This JFSP task has supported the rewriting of 9% of FEIS reviews, addition of reviews that increase FEIS content by 9%, and small updates to 25% of the database. Each FEIS species review addresses the basic biology of the species, fire regimes, fire's role in the life history and persistence of the species, competition and successional patterns, and issues regarding fuel management, prescribed fire, and postfire rehabilitation. …
Burn Severity Mapping Using Simulation Modeling And Satellite Imagery, Robert E. Keane, Eva C. Karau, Elizabeth Reinhardt
Burn Severity Mapping Using Simulation Modeling And Satellite Imagery, Robert E. Keane, Eva C. Karau, Elizabeth Reinhardt
Joint Fire Science Program Research Project Reports
As wildfires becomes an increasingly important issue affecting our nation’s landscapes, fire managers must quickly assess possible adverse fire effects to efficiently allocate resources for rehabilitation or remediation. While burn severity maps derived from satellite imagery can provide a landscape view of relative fire impacts, fire effects simulation models can also provide spatial fire severity estimates along with the biotic context in which to interpret severity. In this project, we evaluated two methods of mapping burn severity for four wildfires in western Montana using 64 plots as field reference: 1) an image-based burn severity mapping approach using the Differenced Normalized …

Carbon Cycling At The Landscape Scale: The Effect Of Changes In Climate And Fire Frequency On Age Distribution, Stand Structure, And Net Ecosystem Production., Michael G. Ryan, Daniel M. Kashian, Erica A.H. Smithwick, William H. Romme, Monica G. Turner, Daniel B. Tinker
Joint Fire Science Program Research Project Reports
Understanding the interactions between climate, fire and forest characteristics-- and how carbon dynamics are affected by these factors--remains an important challenge in ecology. As the size and severity of fires in the western US continues to increase (Westerling et al. 2006), it has become increasingly important to understand carbon dynamics in response to fire. In this study, we investigated these key interactions in the landscape of Yellowstone National Park (YNP). We asked how initial post-fire heterogeneity in forest structure (especially tree density and stand age) controls carbon dynamics over the full life cycle of individual forest stands, and how climate-mediated …

Delayed Tree Mortality Following Fire In Western Conifers, Sheri Smith, Danny Chuck, Elizabeht Reinhardt, Kevin Ryan, Charles Mchugh
Joint Fire Science Program Research Project Reports
We developed 3-year post-fire mortality models for 12 western conifer species by pooling data collected from multiple fire-injury studies. Models were developed for white fir, red fir, subalpine fir, incense cedar, western larch, lodgepole pine, whitebark pine, ponderosa pine, Jeffrey pine, sugar pine, Engelmann spruce, and Douglas-fir. Two sets of models were created, one for use in pre-fire planning where only crown injury and DBH were potential variables, and a second, optimal model for use in post-fire planning that used all significant variables. Predictive accuracy of all models was compared to the accuracy of the mortality model currently used in …
Effects Of Fuels Treatments And Wildfire On Understory Species And Fuels In The Ponderosa Pine Zone Of The Colorado Front Range, Paula Fornwalt, Merrill Kaufmann
Effects Of Fuels Treatments And Wildfire On Understory Species And Fuels In The Ponderosa Pine Zone Of The Colorado Front Range, Paula Fornwalt, Merrill Kaufmann
Joint Fire Science Program Research Project Reports
The first clear indication that unnaturally dense forest conditions existed in ponderosa pine – Douglas-fir forests of the Colorado Front Range was the Buffalo Creek Fire, a large, catastrophic wildfire that burned in 1996. Ongoing research in the Front Range indicated that the Buffalo Creek Fire likely would have burned very differently under pre-settlement forest conditions; early photographs and written descriptions, as well as fire history and stand reconstruction data, all suggested that historically these forests were characterized by a matrix of low-density forests and shrubland or grassland openings that was created and maintained by a mixed-severity fire regime. As …

Effects Of Mechanically Generated Slash Particle Size On Prescribed Fire Behavior And Subsequent Vegetation Effects, Richy J. Harrod, David W. Peterson, Roger Ottmar, Peter Ohlson, Brad Flatten, Arlo Vanderwoude
Joint Fire Science Program Research Project Reports
Forest managers have begun to restore ecosystem structure and function in fire-prone ecosystems that have experienced fire exclusion, commodity based resource extraction, and extensive grazing during much of the 20th century. Mechanical thinning and prescribed burning are the primary tools for thinning dense stands and restoring pre-settlement forest structure, reducing the likelihood of devastating crown fires. Mechanical thinning can be costly when trees are nonmerchantable and prescribed burning can be risky unless fuel loadings are first reduced. Furthermore, stands that remain dense after commercial thinning can produce undesirable wildland fire- or even prescribed fire- effects on vegetation and soils. Land …

Evaluating The Efficacy And Ecological Impacts Of Baer Slope Stabilization Treatments On The Pot Peak/Deep Harbor Wildfire Complex, David W. Peterson, Richy J. Harrod, Terry Lillybridge, Mel Bennett
Joint Fire Science Program Research Project Reports
Post-fire slope stabilization treatments are often prescribed for severely burned areas of a wildfire, through burned area emergency response (BAER), to reduce erosion, maintain soil productivity, protect water quality, and reduce risks to human life and property. Prescribed slope stabilization treatments can include seeding of cereal grains or grasses, fertilization, mulching, and installation of physical barriers across slope contours (e.g., contour-felled logs and straw wattles). Seeding and fertilization treatments have been proposed following several high severity wildfires in the Pacific Northwest. These treatments are designed to reduce erosion by supplementing native vegetation recovery with additional populations of fast-growing species (seeding) …

An Automated System For Evaluating Bluesky Predictions Of Smoke Impacts On Community Health And Ecosystems, Robert Solomon
Joint Fire Science Program Research Project Reports
Predictions of smoke impacts on communities and ecosystems are currently being made by the BlueSky smoke forecast system; providing real-time predictions of surface smoke concentrations from prescribed fire, wildfire, and agricultural burn activities. Currently operational in the Pacific Northwest, BlueSky has already a demonstrated success regarding what inter-agency collaboration can accomplish. A critical component of BlueSky that needed to be addressed was the development of an automated verification system to evaluate predicted impacts from smoke on communities and ecosystems. A verification system is necessary because land managers need to evaluate their burn decisions against potential National Ambient Air Quality Standard …
