Book Description
This report describes a new set of standard fire behavior fuel models for use with Rothermels surface fire spread model and the relationship of the new set to the original set of 13 fire behavior fuel models. To assist with transition to using the new fuel models, a fuel model selection guide, fuel model crosswalk, and set of fuel model photos are provided.

Book Description
Even before the myth of Prometheus, fire played a crucial ecological role around the world. Numerous plant communities depend on fire to generate species diversity in both time and space. Without fire such ecosystems would become sterile monocultures. Recent efforts to prohibit fire in fire dependent communities have contributed to more intense and more damaging fires. For these reasons, foresters, ecologists, land managers, geographers, and environmental scientists are interested in the behavior and ecological effects of fires. This book will be the first to focus on the chemistry and physics of fire as it relates to the ways in which fire behaves and the impacts it has on ecosystem function. Leading international contributors have been recruited by the editors to prepare a didactic text/reference that will appeal to both advanced students and practicing professionals.

Book Description
A First Order Fire Effects Model (FOFEM) was developed to predict the direct consequences of prescribed fire and wildfire. FOFEM computes duff and woody fuel consumption, smoke production, and fire-caused tree mortality for most forest and rangeland types in the United States. The model is available as a computer program for PC or Data General computer.

Book Description
Fire managers are increasingly concerned about the threat of crown fires, yet only now are quantitative methods for assessing crown fire hazard being developed. Links among existing mathematical models of fire behavior are used to develop two indices of crown fire hazard-the Torching Index and Crowning Index. These indices can be used to ordinate different forest stands by their relative susceptibility to crown fire and to compare the effectiveness of crown fire mitigation treatments. The coupled model was used to simulate the wide range of fire behavior possible in a forest stand, from a low-intensity surface fire to a high-intensity active crown fire, for the purpose of comparing potential fire behavior. The hazard indices and behavior simulations incorporate the effects of surface fuel characteristics, dead and live fuel moistures (surface and crown), slope steepness, canopy base height, canopy bulk density, and wind reduction by the canopy. Example simulations are for western Montana Pinus ponderosa and Pinus contorta stands. Although some of the models presented here have had limited testing or restricted geographic applicability, the concepts will apply to models for other regions and new models with greater geographic applicability.

Book Description
A story of hope and friendship, in which resilience trumps tragedy in the wake of a forest fire. After moving from the city, one boy discovers his new home in the woods isn't so bad—there is friendship in the midst of the forest. But when he spots a fire on the horizon that soon engulfs everything he's come to know—the bugs, the plants, the fox who keeps him company—he is forced to flee. When his newfound comfort goes up in smoke, how can he ever feel at home again? In a forest fire, so much can change in an instant. But both fox and boy learn that there are some things fire cannot burn. With time, the forest will regrow, the animals will return to their home, and so will the boy and his mom. As we all search for tools for understanding the destruction of forest fires, this touching story shows that hope, friendship, and resilience shine the brightest. TIMELY: As fires rage over a wider swath of the United States and internationally, and as fire season lengthens year after year, and sets new records year after year, these are themes communities are engaging with daily during fire season. WRITTEN BY A FIREFIGHTER: The author-illustrator was a volunteer firefighter, giving him a unique perspective on the topic of forest fires. EMOTIONALLY RESONANT: This moving story ends with rebuilding—both for humans and for nature—and with a truly uplifting message of resilience. COMMUNITY-BUILDING: A wonderful resource for families and communities experiencing the aftermath of a fire or other natural disasters, as well as anyone looking to empathize with, and better understand, those communities in need. CLASSROOM RESOURCE: Not only is this the perfect resource for talking about topics like the environment, natural disasters, forest management, and emergency preparedness, this book will also spark important conversations about coping with personal and community tragedies. The author-illustrator reflects on his own experiences with forest fires in the autho's note, and backmatter provides additional context. Perfect for: Parents, Educators, Nature lovers

Book Description
Accurate, high-resolution fire behavior prediction is a critical component of fire management decision-making before and during fires. Prometheus is a deterministic fire growth simulation model that was developed to help fire managers to understand the probable consequences of their decisions. It uses spatial input data on topography (slope, aspect, and elevation), fuel types, and weather to simulate fire growth by applying Huygens principle of wave propagation to the rate-of-spread predictions from the Canadian Forest Fire Behavior Prediction System of the Canadian Forest Fire Danger Rating System. This approach produces detailed fire perimeters at user-specified display time step intervals. Each active vertex along the perimeter has corresponding fire behavior output. Exported fire perimeters are compatible with geographic information systems. Additionally, three interpolation techniques are available to produce optional raster fire behavior outputs. This report documents the structure of the Prometheus model and an assessment of its performance. The report includes a general discussion of approaches to the modeling of fire growth simulation and explains the vector propagation technique used in Prometheus. The limitations and assumptions of applying the model, as well as the most appropriate directions for future research, are also discussed.
