Modifying Fofem To Predict Mortality Of The Longleaf Pine Species, Shari Anstedt
Joint Fire Science Program Briefs (2007-2012)
Once the dominant overstory tree across much of the Southeastern United States, the longleaf pine species declined until it faced a high risk of extinction. But due to recent interest in longleaf pine, there is a new focus on managing and restoring the species. Historically, fire has been an important component in maintaining the longleaf pine ecosystem. To help recreate the pre-settlement conditions in which longleaf flourished, prescribed burning is being used. There is concern, however, that by using fire as a management tool, some trees could be lost due to fire-induced mortality. Therefore, a balance must be reached between …

Introducing Fuelcalc: A New Tool That Helps Turn Static Inventory Data Into Actionable Information, Shari Anstedt
Joint Fire Science Program Briefs (2007-2012)
Fuel and fire managers perform fuel treatments to manage and restore ecosystems and protect resources. In order to plan effective fuel treatments that accomplish objectives, managers need to analyze fuel conditions and document the expected fire behavior and fi re effects both before and after fuel treatment. To help accomplish these goals, a new software tool named FuelCalc was created. FuelCalc facilitates use of a wide range of inventory data and fuel characteristics to help calculate fuel quantities and qualities to estimate potential fire behavior, fire effects, and smoke production. By linking with a number of existing software systems and …

After The Fire: Assessing Post-Treatment Effects On Fine Fuels In The Sierra Nevada, Shari Anstedt
Joint Fire Science Program Briefs (2007-2012)
In the mixed conifer forests of the Sierra Nevada, it appears that fire dynamics have changed from predominantly low and moderate intensity surface fires to a greater proportion of larger, stand-replacing fires. To help reduce fuels and speed the restoration process, the Forest Service harvests dead trees and uses herbicides to control early stages of shrubs. But there are concerns about these post-burn restoration treatments and their infl uence on emerging fine fuels. Some of these treatments have been linked to an increase in annual grass invasions, specifi cally non-native grasses, which have the potential to significantly alter fuel characteristics, …

Changes In Public Responses To Wildland Fuel Management Over Time, Joy Drohan
Joint Fire Science Program Briefs (2007-2012)
This study compared citizen responses to surveys in 2002 and 2008 about fuels reduction programs by federal land management agencies. The researchers attempted to identify factors that influence public opinion and promote citizen support for agency actions. The study design allowed comparisons over time among individuals and in seven locations in the Midwest and western U.S. The researchers found key commonalities and differences in responses among sites. They identified important fire-related activities (e.g., signifi cant fires, fuel treatments, formation of citizen groups, community wildfi re protection planning) at each location in the years between the two surveys to understand what …
A New Online Tool And Estimates For Hand-Pile Biomass And Smoke Production,

A New Online Tool And Estimates For Hand-Pile Biomass And Smoke Production, Shari Anstedt
Joint Fire Science Program Briefs (2007-2012)
To help reduce the chance for high-severity fires in the western United States, thinning of the forest understory, midstory and overstory has become a necessity. In some cases, the resulting surface fuels are piled by hand and burned. As this two-part treatment method becomes more widely-used, fire managers need the ability to calculate the biomass of hand-piled fuels so they can better estimate the potential emissions and smoke impacts from their disposal by burning. Since machine-constructed piles were sampled in a previous study, researchers were able to use this past research as a point of departure to develop methods to …

Mitigating Old Tree Mortality In Long-Unburned,Fire-Dependent Forests: A Synthesis, Sharon M. Hood
Joint Fire Science Program Synthesis Reports
This report synthesizes the literature and current state of knowledge pertaining to reintroducing fire in stands where it has been excluded for long periods and the impact of these introductory fires on overstory tree injury and mortality. Only forested ecosystems in the United States that are adapted to survive frequent fire are included. Treatment options that minimize large-diameter and old tree injury and mortality in areas with deep duff and methods to manage and reduce duff accumulations are discussed. Pertinent background information on tree physiology, properties of duff, and historical versus current disturbance regimes are also discussed.

Post-Fire Treatment Effectiveness For Hillslope Stabilization, Peter R. Robichaud, Louise E. Ashmun, Bruce D. Sims
Joint Fire Science Program Synthesis Reports
This synthesis of post-fire treatment effectiveness reviews the past decade of research, monitoring, and product development related to post-fire hillslope emergency stabilization treatments, including erosion barriers, mulching, chemical soil treatments, and combinations of these treatments. In the past ten years, erosion barrier treatments (contour-felled logs and straw wattles) have declined in use and are now rarely applied as a post-fire hillslope treatment. In contrast, dry mulch treatments (agricultural straw, wood strands, wood shreds, etc.) have quickly gained acceptance as effective, though somewhat expensive, post-fire hillslope stabilization treatments and are frequently recommended when values-at-risk warrant protection. This change has been motivated …

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
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 …

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 …
