Vegetation is mapped using predictive landscape models based on extensive field-referenced data, satellite imagery and biophysical gradient layers using classification and regression trees. LANDFIRE uses vegetation products to create fuel and fire regimes data. Most vegetation products use NatureServe's Ecological Systems classification, meeting the requirement that map units be identifiable, scalable, and model-able. The NatureServe Explorer provides descriptions for each ecological system including species, distribution and classification information.
