Disturbance

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

bullet Landsat satellite imagery
bullet Burned Area Reflectance Classification (BARC)
bullet Rapid Assessment of Vegetation Condition
after Wildfire (RAVG)
bullet Monitoring Trends in Burn Severity (MTBS)
bullet LF Events Geodatabase
bullet User contributed data
bullet Other ancillary data

Products
DisturbanceTransition
Disturbance 1999-2014 - provide temporal and spatial information related to landscape change to model vegetation transitions and inform subsequent updates to LF vegetation, fuel, and other data Vegetation Transition Magnitude - provides a summary of the relationship between disturbance types and resulting effects on the vegetation in terms of changes in life-form and canopy cover
Fuel Disturbance - integrated composites of individual disturbance years recoded by disturbance type, disturbance severity, and time since disturbance and screened for non-burnable vegetation to meet fuel transition mapping requirements Forest Vegetation Transitions Database (FVTDB) - contains nationwide forest vegetation transition information and tools to summarize and sort several disturbance types (Fire, Mechanical, Insects and Disease, Windthrow). The database contains vegetation transition rules in tabular format depicting relationship between disturbance type, severity, and time-since-disturbance and its effect on existing vegetation type, cover, and height
Vegetation Disturbance - integrated composites of individual disturbance years recoded by disturbance type, disturbance severity, and time since disturbance to meet vegetation transition mapping requirements Non-forest Vegetation Transitions Database (NFVTDB) contains nationwide non-forest vegetation transition information and tools to summarize and sort several disturbance types (Chemical, Fire, Mechanical) as well as transitions without disturbance or succession. The database contains vegetation transition rules in tabular format depicting the relationship between disturbance type, severity, and time-since-disturbance and its effect on existing vegetation type, cover, and height
Public Events Geodatabase - collection of recent natural disturbance and land management activities used to update existing vegetation and fuel layers Forest Vegetation Simulator Disturbance Database (FVSDDB) — Database deliverable contains LF FVS disturbance analysis outputs for fire, insect and disease, wind and mechanical disturbances. Each disturbance type was modeled at a high, moderate and low severity and represented at three time-steps post disturbance

Learn how disturbance data impacts LF data products.

Application

The disturbance products allow LF 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.
