U.S. Forest Service Post-Fire Vegetation Conditions on the National Forests


Post-Fire Vegetation Conditions on the National Forests

This website offers an initial description of post-fire vegetative conditions using the Rapid Assessment of Vegetation Condition after Wildfire (RAVG) process. The RAVG program assesses wildfires that burn at least 1,000 acres of forested National Forest System (NFS) lands (500 acres for Regions 8 and 9 as of 2016), beginning with fires that occurred in 2007. These fires result in direct losses of vegetative cover and many of the benefits associated with forested ecosystems.

NFS lands experience thousands of wildfires every year, most of which are relatively small. The largest fires typically account for 90% of the total acreage burned. RAVG analysis provides a first approximation of areas that may require reforestation treatments after a fire. These reforestation treatments would re-establish forest cover and restore associated ecosystem services. This initial approximation could be followed by a site-specific diagnosis and development of a silvicultural prescription identifying reforestation needs.


  • Due to leaf-off conditions and observation factors that affect the quality of satellite imagery, RAVG assessments for deciduous forest fires that burn during the late season may be delayed until spring of the following year. Please contact us if you have questions about a specific fire of interest.
  • RAVG data is not available for Region 5 (California) prior to 2008. Visit the U.S. Forest Service Pacific Southwest Region: The Threat of Deforested Conditions in California's National Forests website for information prior to 2008.
  • RAVG analysis products for wildfires below the size threshold described above as well as for prescribed fires are provided on a cost reimbursable basis. Please contact the Geospatial Technology and Applications Center (GTAC) (formerly the Remote Sensing Applications Center - RSAC) at telephone number (801) 975-3800 to request RAVG assessments for these types of fires.

NOTE: The following RAVG Query Tool requires the Adobe Flash Player. Depending upon your browser, you may have to install the player, and/or allow it to play for the query tool to work.
