"With LANDFIRE, you can view and download geospatial layers and data products that depict the nation's major ecosystems, wildlife habitat, vegetation or canopy characteristics, landscape features, and wildland fire behavior, effects, and regimes.
These data layers traverse jurisdictional land boundaries and provide the public free data products for numerous applications, including wildland fire management and landscape conservation. LANDFIRE is a shared effort between the U.S. Department of Agriculture Forest Service and the U.S. Department of the Interior."
This presentation, given by Matt Rollins at the Association for Fire Ecology's 5th International Fire Ecology and Management Congress in Portland, OR in December 2012, provides an overview of LANDFIRE past, present and future.
