Wildland Fire Decision Support Tools Managing Long Duration Wildfires Workshop Salt Lake City, UT April 30 – May 1, 2008 Missoula, MT May 6-7, 2008
Wildland Fire Decision Support System • National Fire and Aviation Executive Board chartered WFDSS in June 2005: • Goal: • develop a scaleable decision support system for agency administrators, • utilize appropriate fire behavior modeling, economic principles, and information technology, • support effective wildland fire decisions consistent with Resource and Fire Management Plans.
Planned WFDSS Development and Expansion • Create a process that: • Documents strategic decisions, • Provides decision support, • Is linear, scalable, progressive, and responsive to fire complexity, • Is applicable to all wildland fires as a single process, • Is spatially oriented, graphically displayed, with no reliance on large text input requirements, • Is Internet-based to provide risk and decision sharing simply and efficiently.
Planned WFDSS Milestones • Accelerated working decision components available June 2007, • Working prototype available June 2008, • May have limited structural components available, • Will be tested as replacement for WFSA, WFIP, LTIP, • Delivery of WFDSS by February 2009.
Decision Support Tools • FSPro • FARSITE • FlamMap • BehavePlus • RERAP • FireFamilyPlus • NFDRS • Fuel Moisture Monitoring • Wind modeling • RAVAR • SCI
FSPro – Fire Spread Probability • A modeling tool developed from FARSITE, FlamMap, and RERAP applications, • Calculates and maps fire spread probability across a landscape and uses many weather scenarios, • Is probabilistic not deterministic, • Gives managers: • Visual indication of probabilities of spread, • Supports formulation of strategy and tactics, • Helps prioritize actions, • Is not a fire spread perimeter map, • Available in WFDSS.
Fire Spread Probability Results What is the probability of each point of concern being affected by fire?
Summer 2007:Pattengail Fire results helped Area Command decided to move resources to another fire for a few days*FSPro results displayed in WFDSS on Topographic map
Summer 2007:Meriwether Fire results also helped decision makers relocate resources*FSPro results displayed in WFDSS with fire perimeter and Google Earth

FARSITE – Fire Area Simulator • A two-dimensional fire growth simulation model, • Computes fire behavior and spread over a range of time under heterogeneous conditions of terrain, fuels, and weather, • Is deterministic not probabilistic, • Provides information on: • Where will the fire go? • How large will the fire get? • When might the fire reach a location? • When weather data quality is high – is the best tool.
FlamMap – Spatial fire behavior mapping • A spatial fire behavior mapping and analysis program, • Provides a landscape view, more simplistic, • Computes potential fire behavior characteristics, • Uses constant weather and fuel moisture conditions, • Minimum travel time and treatment optimization options are available, • Can be viewed as “spatial Behave” or map-based Behave, • Does not go into the same depth as Behave.

BehavePlus – Fire behavior modeling • A modeling system that is a collection of models, • Describes fire behavior, fire effects, and the fire environment, • Deterministic not probabilistic, • Produces tables, graphs, and simple diagrams, does not produce maps, • Very detailed for one location.
FireFamilyPlus – Fire Climatology and Occurrence • A program that combines fire climatology and occurrence analysis capabilities into a single program, • Allows users to summarize and analyze weather observations, link weather with fire occurrence, and compute fire danger indices for NFDRS and CFFDRS, • Provides weather data for FARSITE and FlamMap, • Limited to weather and fire danger information only, not fire behavior.
RERAP – Rare Event Risk AssessmentProcess • A program to estimate the risk of a fire reaching a specific point of concern, • Incorporates weather, fuels, topography, and fire spread model, • Produces straight line transects, • Is probabilistic, not deterministic, • Weather data dependent, • Requires significant user interpretation and adjustment.

NFDRS – National Fire Danger Rating System • A system for predicting relative fire danger and potential for wildland fires, • Provides daily fire danger indices and components, • Allows seasonal tracking of trends and identifies periods of highest concerns, • Based on a single daily weather observation, • Limited to accuracy of weather data.
WindWizard- Gridded wind model • Gridded wind model that includes WindWizard and WindNinja, • Provides gridded wind data that can be used for visualization, display and review, and input to fire behavior models, • Highest resolution wind data – displays effects of terrain on wind, • Useful for identifying where fire intensity may be highest, spread rates may be highest, and where spotting may occur, • Increases accuracy of FARSITE and decision making.

Fuel Moisture Monitoring • Process for monitoring and tracking both live and dead fuel moisture contents, • Allows daily, weekly, monthly, and seasonal tracking, • Provides input for fire behavior models, • Provides indicators of fire behavior potential and long-term drought conditions, • Limited by data quality.
Summary • Decision support is markedly important to fire management success and useful at all levels, • Decision support tools provide a range of information, from subjective to quantitative long-term analyses, • Decision support tools incorporate science and technology to reduce uncertainty, better understand complexity and risks, help develop management strategies and operational tactics, and define the situation, • Decision support information does not make decisions, only facilitates them, • Don’t be hesitant to ask for and use decision support information.
