Wildland fires play a critical role in maintaining the ecological integrity of boreal forests in Alaska. Identifying and maintaining natural fire regimes is an important component of fire management. There are numerous research projects that directly or indirectly address historical fire regimes in the Alaskan boreal forest, but many are unpublished, have many unprocessed dendrochronological (tree age and fire scar) samples, or their data were used for other purposes. Furthermore, no assessment of these data exists to understand how fire has historically affected the boreal forest ecosystems of Alaska. The goal of this project was to compile and synthesize existing …

Joint Fire Science Program Research Project Reports
I have submitted several final reports to the Joint Fire Sciences Program over the years but this one is different. This project was funded to write the full proposals for the California Fire Sciences Consortium. We used the funds from this grant to create the team for the consortium and wrote the proposal that was funded by the JFS. In that regard we accomplished all that we had proposed for this project. This report will be relatively brief because the project objective was to write a full proposal for consideration of the JFS Board.

Doubling Knowledge On Fire And Eastern Invasive Plants In The Fire Effects Information System (Feis), Jane Kapler Smith, Kristin Zouhar, Janet L. Fryer
Joint Fire Science Program Research Project Reports
Managers have been coming to the Fire Effects Information System (FEIS) for reviews of scientific knowledge about fire effects since 1986. Prior to this project, FEIS provided relatively little coverage of invasive plant species in the eastern United States: In 2008, the system contained 52 species reviews of eastern invasive plants covering 69 taxa. The system now contains 105 reviews of eastern invasive plants covering 139 taxa. Thus the project has doubled the information in FEIS on eastern invasive plants. In fact, the information has more than doubled, since the numbers above do not include updates of 5 reviews, addition …
Effects Of Blowdown, Salvage Logging, And Wildfire On Regeneration And Fuel Characteristics In Minnesota’S Forests, Shawn Fraver, Brian Palik, John B. Bradford, Doug Shinneman, Anthony D'Amato
Effects Of Blowdown, Salvage Logging, And Wildfire On Regeneration And Fuel Characteristics In Minnesota’S Forests, Shawn Fraver, Brian Palik, John B. Bradford, Doug Shinneman, Anthony D'Amato
Joint Fire Science Program Research Project Reports
The patchiness resulting from a sequence of recent disturbances – blowdown, salvage logging, and wildfire – provided an excellent opportunity to assess the impacts of these disturbances, singly and in combination, on (1) wildfire severity (2) post-disturbance vegetation responses, (3) ecosystem carbon stocks, and (4) soil mercury (Hg) accumulation or loss in jack pine (P. banksiana) forests of northern Minnesota. Considering issue 1, our results suggest that salvage logging reduced the intensity (heat released) of the subsequent fire. However, its effect on severity (impact to the system) differed between the tree crowns and forest floor. Considering issue 2, our results …

Evaluating Post-Fire Salvage Logging Effects On Erosion, Peter R. Robichaud, William J. Elliot, Lee Macdonald, Robert Coats, Joseph W. Wagenbrenner, Sarah A. Lewis, Louise E. Ashmun, Robert E. Brown
Joint Fire Science Program Research Project Reports
Legal challenges have delayed numerous post-fire salvage logging operations, which often results in lost economic value of the burned timber and unrecovered legal expenses. The scientific literature has shed little light on the additive effect of salvage logging operations on post-fire runoff, erosion, flooding, and sedimentation. Hence, there is an urgent need to better understand the impacts of post-fire salvage operations so that land managers can evaluate the relative and cumulative effects of different salvage logging practices. Intensive, multi-scale studies are needed because the effects of post-fire logging are superimposed on the effect of wildfires; rates and processes change according …

Annual grass invasion in the Great Basin has increased fire size, frequency and severity. Post-fire restoration to provide functional native plant communities is critical to improve resistance to weed invasion. Our ability to successfully re-establish mixtures of native grasses, forbs and shrubs, however, is limited. We examined the effects of the standard rangeland drill and a minimum-till drill, seeding strategies for small-seeded species, and Wyoming big sagebrush (Artemisia tridentata Nutt. spp. wyomingensis Beetle & Young) seeding rates on seeding success in burned shrub communities at four sites in the northern Great Basin. Seeded and recovering vegetation, as well as soil …

Evaluation And Improvement Of Smoke Plume Rise Models, Yongqiang Liu Dr., Gary Achtemeier Dr., Scott Goodrick Dr., Bill Jackson Dr., John Qu Dr.
Joint Fire Science Program Research Project Reports
The purpose of this JFSP project was to evaluate and improve the performance of Daysmoke in simulating smoke plume rise of prescribed burning. A combined approach of field measurement, numerical modeling, and dynamical and statistical analysis was used. Smoke plume height was measured with a ceilometer for 20 prescribed burns in the southeastern U.S. The measured data was used to validate Daysmoke simulation. An empirical smoke plume rise model was developed based on the RAWS observations. Daysmoke was improved by including the number of multiple updraft cores. Regional air quality modeling was conducted with smoke plume rise provided by Daysmoke. …

Joint Fire Science Program Research Project Reports
Emissions from wildland (wild and prescribed) fires add to the burden of air pollution and can have adverse impacts on air quality and public health. Numerical models for dispersion and chemical transport, also known as air quality models, can be used to investigate the fire plume evolution and the smoke impacts. However, it is important that the predictive skills of smoke models be evaluated under a wide range of applicable conditions through systematic simulations of past events with existing data. Three models were evaluated in this research: CALPUFF, DAYSMOKE and CMAQ. Different prescribed burn and wildfire episodes occurring throughout the …

Fire will be the proverbial eye-of-the-needle through which many western U.S. mountain, forest, and stream ecosystems will pass as the climate changes. Historic observations show increased dryness and temperatures accompanying more widespread fire and forest die-off. These events may punctuate gradual changes to ecosystems, or may be a mechanism driving stepwise changes in ecosystems. Most western ecosystems are strongly tied to cycles of fire and recovery, and the changing nature of fire will have profound consequences. There is no question that vulnerability assessments of western U.S. ecosystems need to account for fire in their calculus. The biophysical template of the …

Joint Fire Science Program Research Project Reports
The National Wildfire Coordinating Group definition of extreme fire behavior (EFB) indicates a level of fire behavior characteristics that ordinarily precludes methods of direct control action. One or more of the following is usually involved: high rate of spread, prolific crowning/ spotting, presence of fire whirls, and strong convection column. Predictability is difficult because such fires often exercise some degree of influence on their environment and behave erratically, sometimes dangerously. Alternate terms include “blow up” and “fire storm.” Fire managers examining fires over the last 100 years have come to understand many of the factors necessary for EFB development. This …
Fire Ecology And Management Of Non-Forested Ecosystems In Western North America. Final Report: Description Of Organizational Meetings And Development Of A Publication Plan, Matt Brooks
Joint Fire Science Program Research Project Reports
It has been almost 30 years since the last major book on the ecology and management of fire was published that contained extensive information from non-forested ecosystems across western North America (Wright and Bailey 1982). During subsequent years there have been notable books that have focused largely on forested ecosystems (e.g. Agee 1993), and there was one very recent book that addressed many important grassland, shrubland, woodland, and forest areas, but its geographic extent was confined to California (Sugihara et al. 2006). No single book has since matched the geographic scope associated with non-forested ecosystems in western North America as …

Understanding the role of climate variation in governing fire regimes remains one of the central needs in contemporary fire science and management. Ideally, this understanding should encompass both historical and current fire-climatology, and inform both basic science and ecosystem management. In this project, Fire and Climate Synthesis (FACS) we undertook a detailed synthesis of both paleofire and modern fire based on compilations of existing data sets. We also analyzed three major thematic pathways by which climate has impacted fire policy, including direct and indirect climate effects on fire policy. Paleofire. We assembled the largest and most comprehensive data set of …

Fire Regimes Of Montane Grasslands Of The Valles Caldera National Preserve, New Mexico, Donald A. Falk, Craig D. Allen, Robert Parmenter, Thomas Swetnam, Clifford Dils
Joint Fire Science Program Research Project Reports
Montane grasslands are an important ecosystem type in Southwestern landscapes, occurring from the forest borders of piñon-juniper woodland to high elevation subalpine and alpine ecosystems. Thus, they often represent a mosaic element embedded in the forest landscape matrix, playing key roles in processing water and nutrients, and providing habitat for unique suites of species, often at higher levels of diversity than those found in surrounding uplands. Soils, local temperature and moisture gradients, and disturbance all play roles in determining the distribution and extent of montane grasslands. Of these factors, fire plays the most dynamic role in regulating the location and …

Fuel Reduction Treatment Longevity And Crown Response In Interior Ponderosa Pine Forests Of Northern California, Martin W. Ritchie, Carl N. Skinner, Jianwei Zhang
Joint Fire Science Program Research Project Reports
With increasing interest in fuels treatments to address the high risk of severe fires in the western United States, there is an attendant need to quantify the effectiveness of such treatments. In addition to the immediate effect of reducing levels of combustible material and the attendant impact on fire intensity, resource managers also need to quantify or forecast the longevity of such treatments. Treatments that produce significant, but short-lived reductions in risk of severe wildfire may not be meeting the goals and objectives of managers. This temporal component needs further study and is the subject of this proposal. There are …

Joint Fire Science Program Research Project Reports
Fuel management decisions are made within a larger context of resource management characterized by multiple objectives including ecosystem restoration, wildlife management, commodity production (from timber to less traditional forest products), and provision of recreation opportunities and amenity values. Implementation of fuel treatments is strongly influenced by their perceived influence on and compatibility with overarching management objectives. In some cases these objectives may be complementary while in others they may involve difficult tradeoffs. Such tradeoffs are only further complicated by institutional mandates, limited availability of information, and complex ownership patterns. Like natural resource managers across the U.S., those in the Great …

The Communicative Construction Of Safety In Wildland Firefighting, Jody Jahn, Linda Putnam, Anne Black
Joint Fire Science Program Research Project Reports
This document is a summary of a mixed methods dissertation that examined the communicative construction of safety in wildland firefighting. For the dissertation, I used a twostudy mixed methods approach, examining the communicative accomplishment of safety from two perspectives: high reliability organizing (Weick, Sutcliffe, & Obstfeld, 1999), and safety climate (Zohar, 1980). In Study One, 27 firefighters from two functionally similar wildland firefighting crews were interviewed about their crew-level interactions involved in implementing safety rules and firefighting tasks. These critical incident narratives (Flanagan, 1954; Gremler, 2004) were compared to extract workgroup level similarities and differences in interaction patterns relating to …

The Role Of Adaptive Capacity In Creating Fire-Adapted Human Communities, Pamela J. Jakes, Matthew S. Carroll, Travis B. Paveglio, Soren Newman
Joint Fire Science Program Research Project Reports
In this research we sought answers to the question: What are the social characteristics and conditions of human communities that promote adaptive capacity for wildfire? The Quadrennial Fire Review (USDA and USDI 2009) promotes a goal of “achieving fire-adapted communities” in the wildland urban interface (WUI), and identifies metrics for determining whether a community is fire-adapted. While these metrics address some of the biophysical conditions necessary for fire-adapted human communities, they offer little insight into the social elements that promote or sustain adaptive capacity. Adaptive capacity refers to the individual and collective resources, capabilities, and actions that alleviate the risk …

Joint Fire Science Program Research Project Reports
The Forest Vegetation Simulator (FVS) and its associated Fire and Fuels Extension (FFE) have been used to provide information required by larger software systems like the Interagency Fuels Treatment - Decision Support System (IFT-DSS). Interacting with FVS in an automated fashion has been difficult, and simulations with very large numbers of stands, such as those necessary for landscape analyses for fire planning, could take a significant amount of time to process. This project was designed to: (A) develop a requirements document considering Service Oriented Architecture and how that may apply to FVS, and how FVS will be used interactively; (B) …

A major problem in post-fire restoration of semi-arid shrublands dominated by annual bromes is the presence of carryover seed banks that cannot be controlled using conventional methods. These seeds can provide significant competition for seeded species in the years following treatment. We investigated the feasibility of using a naturally occurring seed pathogen, the ascomycete Pyrenophora semeniperda, as a biocontrol organism for eliminating this carryover seed bank. We carried out the necessary technology development to create and apply field inoculum to cheatgrass- or red brome-infested areas (both burned and unburned) at six sites located in three states across two years of …

Fire is a significant and essential disturbance in ponderosa pine ecosystems but the management and the re-introduction of fire across the landscape is a difficult task for land managers. In this study we worked with land managers, stakeholders and researchers to examine the effects of a large wildfire on the Kaibab Plateau in northern Arizona. We analyzed litter and duff depth, downed woody debris and understory vegetation responses to low and high burn severity and assessed the response of the understory vegetation to seeding with Lolium perenne ssp. multiflorum in high severity burn areas. To assist land managers in future …

Joint Fire Science Program Research Project Reports
The use and cost of post-fire emergency stabilization treatments continues to grow. To help maximize the impact of these treatments, many assessment teams use the Erosion Risk Management Tool (ERMiT) erosion model to predict postfire erosion and mitigation effects. However, despite several completed JFSP projects, the long-term effects of these treatments remain unknown, and the ERMiT model has not been validated. Long-term post-fire erosion and runoff data on a variety of mulches and erosion barriers were collected using 12 existing sites throughout the Western U.S. The agricultural straw and wood strand mulch treatments were very effective at reducing erosion and …

Evaluating The Effects Of Pinyon Thinning Treatments At A Wildland Urban Interface, J. R. Matchett, Matthew L. Brooks, Anne Halford, Dale Johnson, Helen Smith
Joint Fire Science Program Research Project Reports
This study evaluated the short-term effects of thinning methods for pinyon pine woodlands at two sites in the southwestern Great Basin. Both cut/pile/burn and mastication treatments were equally effective at reducing the target fuels which were mature, live pinyon trees. Application costs though differed substantially, with the cut/pile/burn technique being less expensive. Thinning treatments increased the abundance of herbaceous vegetation, although in some cases the strength of the increase was constrained by the level of pre-treatment tree dominance. Increases in perennial grass cover and density in response to thinning were usually greatest at lower levels of pre-treatment pinyon dominance, whereas …

Joint Fire Science Program Research Project Reports
Information about historic fire regimes and the departure of current fire regimes from historic conditions is essential for guiding and justifying management actions, such as prescribed burning programs for ecosystem process restoration and fuel reduction. Such information is noticeably lacking for the southern Appalachian Mountains, where human populations are encroaching onto wildland areas, and where decades of fire exclusion have contributed to the decline of fire-associated communities and also to altered fuel loads. We address this knowledge gap via a multi-scale investigation of the variability in fire regimes over time and space using tree-ring reconstructions of fire history and stand …
