About This Project
A national network of experts developed a series of conceptual “state-and-transition” models to describe succession and disturbance dynamics for each type. LANDFIRE then produces nationally standardized maps of vegetation type, vegetation structure, and wildfire fuel conditions. LANDFIRE also maintains data sets on current conditions, described in terms of “fire regime departure.” Departure is expressed by vegetation structural stages and their relative proportions in a given area. Alterations to expected fire regime (e.g., frequency, return interval, intensity), often resulting from land use practices over decades, results in measureable differences in vegetation successional and structural stages (e.g., tree density increasing with decades of wildfire suppression), and signaling “departure.” Highly departed conditions correlate with increasing risk of catastrophic wildfire and a loss of quality habitat conditions for biodiversity.
NatureServe ecologists contribute to the maintenance and advancement classification, mapping, and modeling efforts by LANDFIRE.
LANDFIRE created and currently updates 30-meter raster data describing vegetation, major disturbances, and fire/fuel characteristics for the United States. It is the first midlevel-resolution national mapping program providing geospatial products to support natural resource management and fire/fuel planning.
The most recent version, LF_1.1.0, incorporates vegetation transitions for disturbances from 1999 to 2008. Disturbances include fire, vegetation management, weather events, and insect/disease. Disturbance causality in the LANDFIRE disturbance grids 1999–2008 is determined in part using the user-contributed Events geodatabase, which is available for download.
See our Ecological Systems of the United States page to learn about and download our Ecological Systems map and data.
Additional LANDFIRE data are also available including:
- Vegetation type
- Fire-related disturbance
- Geo-referenced vegetation samples
- Historical fire regime and current fire-related conditions
- Surface and vegetation canopy fuels
The multi-agency LANDFIRE effort maintains a series of national data sets in the United States related to wildland fire. These data are used in natural resource assessment, planning, management and monitoring. LANDFIRE data are used in natural resource assessment, planning, management and monitoring. Prior to LANDFIRE, efforts to support decisions for managing wildland fire were made locally. That meant that most decisions were tactical; i.e., how best to fight a wildfire. Strategic approaches to managing wildland fire proactively target resources towards land use and vegetation management that will minimize uncontrollable wildland fire.
Funded under with the National Fire Plan, LANDFIRE was established to make coordinated investments in information, most efficiently developed at the national scale, to ensure that better information was available to state and local jurisdictions to support strategic management decisions.
The NatureServe terrestrial ecological systems classification and staff expertise on vegetation form one foundation for this effort. The vegetation types from these classifications for use as the assessment units for LANDFIRE. Our goal is to provide the ecological assessment units that support the LANDFIRE effort.
By providing reliable information on the location and conditions of vegetation and wildland fire conditions, planners and managers can make better strategic decisions for vegetation management in order to minimize risk of catastrophic losses to life and property, while enhancing the ecological integrity of terrestrial ecosystems.
