Development And Delivery Of Version 2 Of The Fire And Fuels Extension To The Forest Vegetation Simulator, Nicholas Crookston, Stephanie Rebain, Elizabeth Reinhardt, Gary Dixon

Joint Fire Science Program Research Project Reports

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

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 …

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

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

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

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

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

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

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 …

Conversion Of The Bluesky Framework Into Collaborative Web Service Architecture And Creation Of A Smoke Modeling Application, Narasimhan K. Larkin, Sean Raffuse, Daniel Pryden, Alan Healy, Kevin Unger, Tara Strand, Robert Solomon

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 …

Community Wildfire Protection Plans: Enhancing Collaboration And Building Social Capacity, Daniel R. Williams, Pamela J. Jakes, Sam Burns, Antony Cheng, Kristen Nelson, Victoria Sturtevant, Alex Bujak, Rachel Brummel, Stephanie Grayzeck Souter, Emily Saeli Staychock

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 …

Experimental Study Of Local Fire Conditions And Effects On Surface Or Near-Surface Archeological Resources At National Park Service Units – Midwest Region., Jay T. Sturdevant, Rod Skalsky, Cody L. Wienk, Brennan Dolan, Dustin Gonzalez, David Amrine

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

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 …

Enhancing Western Managers’ Knowledge And Use Of Available Economic And Financial Biomass Information And Tools, Todd A. Morgan, Kenneth Skog, Greg Jones, Woodam Chung, Henry Spelter, John Baldridge, Jason Brandt, Dan Loeffler, Jon Songster

Joint Fire Science Program Research Project Reports

The Joint Fire Science Program (JFSP) sponsored this study to enhance the ability of federal land managers to understand and deal with the economic and financial aspects of woody biomass removal as a component of fire hazard reduction treatments. The study objectives were to synthesize the body of economic and financial information and tools currently available to federal land managers in the West, identify managers’ information needs and disconnects from available information, and fill the gaps between existing information and tools versus managers’ awareness of available information and access to tools. The methods used for this study included 1) preparing …

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 …

A Chronosequence Feasibility Assessment Of Emergency Fire Rehabilitation Records Within The Intermountain Western United States, Kevin C. Knutson, David A. Pyke, Troy A. Wirth, David S. Pilliod, Matthew L. Brooks, Jeanne C. Chambers

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 …

Exploring Predation And Animal Coloration Through Outdoor Activity, Joseph J. Fontaine, Karie L. Decker

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Although children often characterize animals by the animals' color or pattern. the children seldom understand the evolutionary and ecological factors that favor particular colors. In this ilrticle. we describe two activities that help students understand the distinct evolutionary stmtegies of warning coloration and camoutlage. Because both of these strategies effectively allow prey animals to avoid predation. they can help explain considerable variation in animal coloration.

Seasonal Patterns Of Song Structure Variation In A Suboscine Passerine, Bruce A. Robertson, Joseph J. Fontaine, Elizabeth Loomis

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Studies of song and its function in suboscine passerines are rare. We examined spatial and temporal variation in song structure in a wild population of Olive-sided Flycatchers (Contopus cooperi) and tested among hypotheses explaining this variation. Repeatable variation in song type was observed both within and among individuals. More than 10% of territorial males expressed atypical song types, i.e., permutations of sequential missing and repeated elements of the typical adult song. Atypical songs were predominantly expressed by unpaired males independent of habitat type. A small fraction of males sang atypical song through the middle of the breeding season, …

Variability In Population Abundance Is Associated With Thresholds Between Scaling Regimes, Donald Wardwell, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Discontinuous structure in landscapes may result in discontinuous, aggregated species bodymass patterns, reflecting the scales of structure available to animal communities within a landscape. The edges of these body-mass aggregations reflect transitions between available scales of landscape structure. Such transitions, or scale breaks, are theoretically associated with increased biological variability. We hypothesized that variability in population abundance is greater in animal species near the edge of bodymass aggregations than it is in species that are situated in the interior of body-mass aggregations. We tested this hypothesis by examining both temporal and spatial variability in the abundance of species in the …

A Neotropical Migrant Bird’S Dilemma— Where To Stop For A Good Meal, Joseph J. Fontaine, Charles Van Riper Iii

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

To learn how migrating birds determine where to stop and find food, scientists from the U.S. Geological Survey, Northern Arizona University, and The University of Arizona studied the behavior of 28 species of neotropical migrant songbirds—warblers, flycatchers, tanagers, and vireos—along the lower Colorado River from 2001 to 2004. They found that, like interstate travelers greeted by restaurant billboards, songbirds flying over Cibola National Wildlife Refuge, Arizona, relied on the flowering of honey mesquite (Prosopis glandulosa) to detect the availability of insects that they prey on. Understanding where and why migrant birds stop will help land managers better protect …

Spatial And Temporal Variation In Climate Change: A Bird’S Eye View, Joseph J. Fontaine, K. L. Decker, S. K. Skagen, C. Van Riper Iii

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Recent changes in global climate have dramatically altered worldwide temperatures and the corresponding timing of seasonal climate conditions. Recognizing the degree to which species respond to changing climates is therefore an area of increasing conservation concern as species that are unable to respond face increased risk of extinction. Here we examine spatial and temporal heterogeneity in the rate of climate change across western North America and discuss the potential for conditions to arise that may limit the ability of western migratory birds to adapt to changing climates. Based on 52 years of climate data, we show that changes in temperature …
