A Proposal To Improve Performance Of The Forest Vegetation Simulator - Fire And Fuels Extension, Dave C. Cawrse, Michael G. Van Dyke, Nicolas Nicholas L. Crookston, Donald Robinson, Sarah Beukema
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 …

Joint Fire Science Program Research Project Reports
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 …

A web-programming project was undertaken to allow users of the online Hand-piled Fuels Biomass Calculator to also estimate the volume, biomass and potential emissions of mechanically piled fuels. Machine pile calculations encoded in the decision support software CONSUME 3.0 were added to the online Calculator to achieve this objective. In addition, the ability to batch process piled fuels data was added to the online Calculator to ease data input for large analysis projects. A stand-alone version of the Calculator was developed for users without access to the Internet. As it is executed within a standard web browser (e.g., Microsoft Internet …
Evaluating The Effects Of Pinyon Thinning Treatments At A Wildland Urban Interface, J. R. Matchett, Matthew L. Brooks, Anne Halford, Dale Johnson, Helen Smith
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 …

Fire Regimes Of The Southern Appalachian Mountains: Temporal And Spatial Variability Over Multiple Scales And Implications For Ecosystem Management, Charles W. Lafon, Henri D. Grissino-Mayer, Sally P. Horn, Robert N. Klein
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 …
Fuel Consumption And Smoke Emissions From Landscape-Scale Burns In Eastern Hardwoods, Matthew Dickinson, Ann Acheson, Robert Kremens
Fuel Consumption And Smoke Emissions From Landscape-Scale Burns In Eastern Hardwoods, Matthew Dickinson, Ann Acheson, Robert Kremens
Joint Fire Science Program Research Project Reports
Our project used remotely-sensed infrared radiation measurements to estimate fuel consumption in eastern mixed-oak forests and facilitated the development of smoke management expertise and processes for complying with EPA regulations in Ohio and Kentucky. As a result of two workshops, Ohio developed a Smoke Management Plan designed to ensure that best management practices were being used across land ownerships and to facilitate mandated information sharing with the Ohio EPA and US EPA. Ohio also established a Prescribed Fire Council as a result of this process. Kentucky opted for a less formal response to EPA regulations, establishing a Prescribed Fire Council …

Developing And Using Fire Scar Histories In The Southern And Eastern United States, Richard P. Guyette, Martin Spetich, Daniel C. Dey
Joint Fire Science Program Research Project Reports
Land managers developing fire management plans in the eastern and southern United States lack quantitative information on historic fire regimes. Twelve new fire histories were developed from dated fire scars on trees from regions where no fire scar history data had existed before in the states of Alabama, Louisiana, Kentucky, Iowa, Wisconsin, and Michigan. Sites represent highly variable climates from extreme cold (with long snow cover duration) to subtropical. All sites utilized oak or pine recorder species that were collected from closed forest to open savanna structures. Pre-industrial mean fire intervals ranged from 3 to more than 35 years at …
Do Annual Prescribed Fires Enhance Or Slow The Loss Of Coastal Marsh Habitat At Blackwater National Wildlife Refuge?, Donald R. Cahoon, Glenn Guntenspergen, Suzanne Baird
Do Annual Prescribed Fires Enhance Or Slow The Loss Of Coastal Marsh Habitat At Blackwater National Wildlife Refuge?, Donald R. Cahoon, Glenn Guntenspergen, Suzanne Baird
Joint Fire Science Program Research Project Reports
The rate of estuarine marsh loss at Blackwater NWR has been high (up to 2,000 ha) during the past 80 years because the vertical buildup of the marsh surface has lagged behind the local rate of relative sea-level rise. In this mineral sediment-poor estuary, marsh vertical development is driven primarily by the accumulation of plant matter in the soil (roots and rhizomes). Thus any activity that affects plant productivity can affect the ability of these marshes to keep pace with sea-level rise. Blackwater NWR has employed an annual prescribed fire regime since the 1970’s to achieve multiple management objectives. However, …
Do Fuel Treatments Reduce Fire Severity? Evaluating Treatment Effectiveness In The 2006 Tripod Complex Fires, Susan J. Prichard, David L. Peterson
Do Fuel Treatments Reduce Fire Severity? Evaluating Treatment Effectiveness In The 2006 Tripod Complex Fires, Susan J. Prichard, David L. Peterson
Joint Fire Science Program Research Project Reports
The 2006 Tripod Complex fires burned over 70,000 ha of dry mixed conifer forests in north-central Washington State. Recent fuel treatments burned in the wildfire offered an opportunity to quantitatively evaluate if fuel treatment effectively mitigated fire severity. We quantified the relative effect of two common fuel treatments: mechanical thinning only (thin) and mechanical thinning followed by prescribed burning (thinRx). Fire severity was markedly different between the two treatments. Over 57% of trees survived in thinRx units versus 19% in thin and 14% in control units. Considering only large-diameter trees (> 20 cm dbh), 73% survived in thinRx units versus …

Effect Of Season And Interval Of Prescribed Burns In A Ponderosa Pine Ecosystem On Tree Growth And Understory Vegetation., W. G. Thies, Becky K. Kerns, Douglas J. Westlind
Joint Fire Science Program Research Project Reports
After decades of fire exclusion many stands now have historically unprecedented (high) levels of fuels and overstocking. As a result these stands have developed a variety of health issues. In response to these problems land managers are using prescribed fire to restore fuel loads and stand stocking to pre-fire exclusion levels. The impacts of season of prescribed burn as well as burn interval are not well understood. Managers need the ability to better predict these impacts on such things as tree mortality from fire, associated insect attack and disease development, tree growth, and plant communities. The “Season of Burn” study …

Joint Fire Science Program Research Project Reports
One-half-acre treatment areas were delineated within prescribed burns. Cutting treatments consisted of chainsaw or brushsaw severing of all rhododendron stems within 6 in of the ground surface. Herbicide and herbicide followed by fire treatments consisted of basal applications of triclopyr or imazapyr in methylated seed oil on each plot. Cutting and burning treatments followed by herbicides utilized foliar applications of triclopyr or imazapyr in emulsions to all resprouting rhododendron. All herbicide plots were randomly split in half for the application of imazapyr or triclopyr on different halves. Analyses of variance and mean separation by LSD were used to compare treatment …

Joint Fire Science Program Research Project Reports
The restoration of historical fuel conditions and fire regimes is one of the primary land management goals in the Shivwits Plateau region of northwestern Arizona. Fire is the primary tool used in this region to reduce fuel loads and shift landscapes back to historical conditions of a low intensity, 8- 15 year return interval, surface fire regime. However, the invasive plant cheatgrass has become the dominant understory vegetation and fuel type following initial fire treatments in many areas. There is significant concern that repeated burning at historically appropriate fire return intervals for ponderosa pine forest will benefit this invasive plant …

Joint Fire Science Program Research Project Reports
This guide describes the benefits, opportunities, and trade-offs concerning fuel treatments in the dry mixed conifer forests of northern California and the Klamath Mountains, Pacific Northwest Interior, northern and central Rocky Mountains, and Utah. Multiple interacting disturbances and diverse physical settings have created a forest mosaic with historically low- to mixed-severity fire regimes. Analysis of forest inventory data found nearly 80 percent of these forests rate hazardous by at least one measure and 20 to 30 percent rate hazardous by multiple measures. Modeled mechanical treatments designed to mimic what is typically implemented, such as thinning, are effective on less than …

Joint Fire Science Program Research Project Reports
The extent and severity of fires in the United States during the last decade has been remarkable. Since 2002, there has been seven years (2002, 2004, 2005, 2006, 2007, 2011, 2012) when over 2.8 million ha have burned, more than twice the previous decade. The extent of recent fire activity has increased risks to lives and property (Cohen 2008; , biodiversity and species-at-risk (Spies et al. 2006), the timber value of forests (Butry et al. 2001) and forests as a carbon sink (Hurteau et al. 2008, 2011). Although one driver of the increase in fire extent, at least in western …

Joint Fire Science Program Research Project Reports
We synthesized post-fire road treatment information to assist BAER specialists in making road rehabilitation decisions. We developed a questionnaire; conducted 30 interviews of BAER team engineers and hydrologists; acquired and analyzed gray literature and other relevant publications; and reviewed road rehabilitation procedures and analysis tools. Post-fire road treatments are implemented if the values at risk warrant the treatment and based on regional characteristics, including the timing of first damaging storm and window of implementation. Post-fire peak flow estimation is important when selecting road treatments. Interview results indicate that USGS methods are used for larger watersheds (>5 mi2) and NRCS …

Joint Fire Science Program Research Project Reports
The idea of offsetting the costs of wildfire hazardous fuels reduction treatments by selling the biomass removed is appealing. There are however challenges to biomass utilization that impedes progress. For instance, the lack of biomass processing capacity may impede progress in some regions, while in other regions an inconsistent supply of biomass available for wood products markets limits private investment. Despite efforts to increase biomass utilization, uncertainty exists of regarding the characteristics necessary to stimulate biomass utilization, effectiveness of agency and local efforts, and the role of partnerships in building the types of capacity necessary to expedite biomass removal. The …
Delivery And Demonstration Of Surface Wind Simulation Tool For Fire Management Decision Support, Mark Finney, Larry Bradshaw, Bret Butler
Delivery And Demonstration Of Surface Wind Simulation Tool For Fire Management Decision Support, Mark Finney, Larry Bradshaw, Bret Butler
Joint Fire Science Program Research Project Reports
One major source of uncertainty in fire behavior predictions is the spatial variation in winds blowing over mountainous terrain. Fire managers have not had access to “real time” predictions of surface wind flow. With the generous support of the JFSP and additional funding from several USDA Forest Service sources a wind simulation tool has been developed and tested. This project had three primary objectives: 1. Support wildland fire incident management teams with surface wind flow simulations. 2. Validate, improve and document the utility of gridded wind as a fire management decision support tool. 3. Produce technical documentation, including a user’s …

This project provided for an improved version of the Fire and Fuels Extension to the Forest Vegetation Simulator (FFE-FVS), a program whose original development was largely financed by the JFSP. The program is widely used by JFSP member agencies and several JFSP-sponsored research projects to support analysis at the stand to large landscape spatial scales. New research results rendered version 1 obsolete and experience with the model demonstrated that some parts of it needed to be improved. Equally important are issues regarding support, training, and system usability. We conducted 42 on-site training sessions over the last 4 years and also …
Does Prescribed Burning In Southern Forests Release Significant Amounts Of Mercury To The Atmosphere?, Thomas A. Waldrop, Mac A. Callahn, John A. Stanturf
Does Prescribed Burning In Southern Forests Release Significant Amounts Of Mercury To The Atmosphere?, Thomas A. Waldrop, Mac A. Callahn, John A. Stanturf
Joint Fire Science Program Research Project Reports
Mercury (Hg) emissions from prescribed fire present a potential impact on air quality that could motivate regulators to further restrict prescribed burning. Atmospheric deposition of Hg (originating from industrial sources) to forests is well documented, and the prescribed burning of two to four million acres per year in the South recycles an unknown (but potentially significant) amount of Hg into the atmosphere and surface waters by volatilization and post-fire runoff. This and other environmental concerns present a significant challenge to local land managers who use prescribed fire. Our objectives were (1) to estimate local and South-wide emission of Hg due …

Effect Of Mechanical Mastication Followed By Prescribed Fire On Mycorrhizas And Hypogeous Fungi In Mixed Hardwood Chaparral, Darlene Southworth, Jennifer Gibson, Jessica Donohue, Jonathan Frank, Kate Wagner, Jason Lambert, Acacia Baldner
Joint Fire Science Program Research Project Reports
The purpose of this study was to examine the effects of mechanical mastication followed by prescribed fire on mycorrhizal fungi and hypogeous sporocarps. A dense fire-prone mixed hardwood-conifer chaparral comprises a significant component of vegetation at Whiskeytown National Recreation Area. Prescribed burns, as fuel reduction treatments, are limited by air quality restrictions and narrow climatic conditions appropriate for burnings. Brush mastication is a fast and inexpensive tool commonly used by land managers to reduce ladder fuels. However, a dense layer of chipped debris remains, which, when burned, heats the soil more than ladder fuels. The upper layers of mineral soil …

Synthesis Of Knowledge On The Effects Of Fire And Thinning Treatments On Understory Vegetation In U.S. Dry Forests, Anne M. Bartuszevige, Patricia L. Kennedy
Joint Fire Science Program Research Project Reports
A century of fire exclusion in dry forests across the United States has resulted in high fuel loads and increasing dominance by fire-intolerant vegetation. Federal, state, and private agencies have adopted a goal of managing forests to reduce the risk of high-severity wildfire. Forest managers use a variety of tools to create desired conditions within forests; the most common are prescribed fire and mechanical thinning. These two treatments may be used separately or in combination, depending on restoration goals for the forest stand. Before these treatments can be applied, managers must justify their choice by documenting the effects of the …
