Data Products ›› Disturbance

Disturbance products are developed to help inform updates to LANDFIRE data to reflect change on the landscape caused by management activities and natural disturbance. They are a compilation of data from:

Landsat satellite imagery Burned Area Reflectance Classification (BARC) Rapid Assessment of Vegetation Condition after Wildfire (RAVG)

Monitoring Trends in Burn Severity (MTBS) LANDFIRE Refresh events User contributed data Other ancillary data

LANDFIRE 2008 (LF_1.1.0) Fuel Disturbance 2008 (FDIST2008) for Hawaii, zone 79, was updated 6/5/12. FDIST2008 was reclassified in certain areas of zone 79. Users are advised to delete local copies of these layers downloaded prior to June 5, 2012 and download the updated versions. We regret any inconvenience this may cause. LANDFIRE 2008 (LF_1.1.0) disturbance layers for zones 37, 46, 48, 54, 98, and 99 are updated 5/1/12. The disturbance layers were updated due to corrected input layers. Updated layers are Disturbance 1999 -2008 (DISTYEAR), Fuel Disturbance 2008 (FDIST2008), and Vegetation Disturbance 2008 (VDIST2008). Users are advised to delete local copies of these layers downloaded prior to May 1, 2012 and download the updated versions. We regret any inconvenience this may cause. Some disturbance layers for zone 41 are updated as of 1/30/12. A windstorm landscape change event was excluded in the original processing. The windstorm event was added to the processing inputs and the following 3 layers are updated: Disturbance 1999 (DIST1999), Fuel Disturbance 2008 (FDIST2008), and Vegetation Disturbance 2008 (VDIST2008). Users are advised to delete local copies of these disturbance layers downloaded prior to 1/30/12 and download the updated versions. We regret any inconvenience this may cause. Some disturbance layers for zones 10 and 19 are updated as of 1/30/12. An extraneous landscape change event polygon was included in the original processing. The extraneous polygon was removed and the following 3 layers are updated: Disturbance 2000 (DIST2000), Fuel Disturbance 2008 (FDIST2008), and Vegetation Disturbance 2008 (VDIST2008). Users are advised to delete local copies of these disturbance layers downloaded prior to 1/30/12 and download the updated versions. We regret any inconvenience this may cause. posted 05-JUN-12 LANDFIRE 2008 (LF_1.1.0) Fuel Disturbance 2008 (FDIST2008) for Hawaii, zone 79, was updated 6/5/12... posted 01-MAY-12 LANDFIRE 2008 (LF_1.1.0) disturbance layers for zones 37, 46, 48, 54, 98, and 99 are updated 5/1/12... posted 01-FEB-12 Some disturbance layers for zone 41 are updated as of 1/30/12... posted 01-FEB-12 Some disturbance layers for zones 10 and 19 are updated as of 1/30/12...
Disturbance
Disturbance 1999-2008 - provide temporal and spatial information related to landscape change to model vegetation transitions and inform subsequent updates to LANDFIRE vegetation, fuel, and other data
Fuel Disturbance YEAR and Vegetation Disturbance YEAR - composites of Disturbance 1999-2008 recoded by disturbance type, disturbance severity, and time since disturbance to meet fuel and vegetation assignment needs
Other Public Events Geodatabase - collection of recent natural disturbance and land management activities used to update existing vegetation and fuel layers

Application

The disturbance products allow LANDFIRE products to remain current and relevant. These data are useful in change detection analysis and other analysis that requires up-to-date land cover information.
