Bringing The Fire Effects Information System Up-To-Date And Improving Service To Land Managers, Jane Kapler Smith, Fire Modeling Institute Information Team
Joint Fire Science Program Research Project Reports
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
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
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
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 …
Expansion Of The Southern Variant Of The Fire And Fuels Extension For The Forest Vegetation Simulator, S. M. Zedaker, S. A. Rebain, P. J. Radtke
Expansion Of The Southern Variant Of The Fire And Fuels Extension For The Forest Vegetation Simulator, S. M. Zedaker, S. A. Rebain, P. J. Radtke
Joint Fire Science Program Research Project Reports
This project specifically addressed AFP 2006-3, Task 3, by providing guidance for maintaining effective fire and non-fire fuels treatments, with the aim of supporting long-term fuels management. The overall goals of the project were to parameterize, expand, and improve the Southern Variant of the Fire and Fuels Extension (FFE) to the Forest Vegetation Simulator (FVS) with the best data currently available, to identify data weaknesses and gaps that may require additional research to reduce the uncertainty of Southern FFE model predictions, and to determine a validation framework for the Southern FFE. A wide variety of fire and fuels data and …
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
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) …
Evaluation Of Science Delivery Of Joint Fire Science Program Research, David Seesholtz
Evaluation Of Science Delivery Of Joint Fire Science Program Research, David Seesholtz
Joint Fire Science Program Research Project Reports
Since its inception in 1998, the Joint Fire Science Program (JFSP) has funded over 400 projects. The Joint Fire Science Program has long recognized that the investments made in wildland fire science need to be accompanied by an emphasis on science interpretation and delivery. Program success is ultimately measured by how well information from research efforts is being conveyed to resource managers and end users, and whether this information is improving management decisions. This study reviewed a sample of environmental documents from three JFSP sponsoring agencies to determine to what extent JFSP research is being incorporated into local planning efforts …
Mixed-Fire Regime Of The Klamath-Siskiyou: New Postfire Potentials, Marjie Brown
Mixed-Fire Regime Of The Klamath-Siskiyou: New Postfire Potentials, Marjie Brown
Joint Fire Science Program Briefs (2007-2012)
Effects of postfire management are becoming more important as wildfire frequency, extent and severity appear to be increasing. Researchers set out to measure the effects of postfire salvage logging on fuel loads, vegetation, and wildlife communities in the Klamath-Siskiyou region of the Pacific Northwest. Natural recovery processes revealed some important findings that provide viable options for managers whose objectives include regenerating forests, sustaining natural processes, and maintaining landscape biodiversity. The researchers found that the mixed-severity fire regime of the region, which includes patches of repeated severe fire, supports abundant, natural postfire conifer regeneration and regionally significant biodiversity. Salvage logging aimed …
Burned Landscapes Of Southwestern Oregon: What’S In It For Northern Spotted Owls?, Marjie Brown
Burned Landscapes Of Southwestern Oregon: What’S In It For Northern Spotted Owls?, Marjie Brown
Joint Fire Science Program Briefs (2007-2012)
Northern spotted owls are known to spend time in areas burned by wildfire, but there has been little scientifi c investigation of how and why they use these landscapes. A trio of wildfi res in southwestern Oregon during the summers of 2001 and 2002 burned through dozens of documented spotted owl territories, providing a rare opportunity to study many important aspects of how these raptors respond to wildfi re in dry forest ecosystems. For this project researchers used radio telemetry and demographic surveys to investigate habitat selection, home range size, occupancy, productivity and survival of spotted owls within and adjacent …
