The International Multiproxy Paleofire Database (IMPD) is an archive of fire history data derived from natural proxies. The IMPD, which includes data from tree scars and establishment data, and charcoal in sediment records, has been established with guidance from an Advisory Board to provide a permanent repository for high-quality paleofire records from around the world. For more information about paleofire data, see our Introduction to Fire History Reconstruction.
