One of eight maps produced during the progress of the Zaca
Fire, Santa Barbara County CA. This large, long-duration
incident threatened thousands of homes, oil and gas pipelines,
communication towers, municipal supply watersheds, and dozens
of recreation and historic sites.
RAVAR is the primary fire
economics tool within the Wildland Fire Decision Support System
(WFDSS). RAVAR was developed by the Rocky Mountain Research
Station’s Missoula Forestry Sciences Lab. RAVAR identifies
the primary resource values threatened by ongoing large fire
events. RAVAR is typically integrated with the FSPro model
to identify the likelihood of different resources being impacted
in the potential fire path of an ongoing event but can be
linked to any expected fire spread polygon.
was initially tested in 2005 with increased testing and prototype
applications delivered during the 2006, 2007 and 2008 seasons.
During the active fire season of 2007, over 100 RAVAR reports
were delivered through the web-based WFDSS to fire events
in real time. The WFDSS was developed by the Forest Service
and is currently being adopted by Department of Interior agencies.
RAVAR can help agency administrators,
incident managers, and fire planners develop wildland fire
suppression strategies by rapidly identifying and quantifying
the significant resource values most likely to be threatened
by an ongoing fire event. In the area command setting, RAVAR
has been shown to be useful in prioritizing fires for assignment
of scarce suppression resources. Additionally, RAVAR can help
support the development of Long Term Implementation Plans
(LTIP), and will be a critical component of the WFDSS as the
system transitions to replace the Wildland Fire Situation
Analysis in 2009.
