This topic can be presented in many ways. History can be projected by dendrochronology, which is the dating of events, environmental change, and archaeological artifacts by using the characteristic patterns of annual growth rings in timber and tree trunks. Fire history can also be presented as paleontology, which uses soil sediment deposits, pollen, or charcoal records. Archival records use historical records such as a fire atlas, library records, annual reports of burned areas, etc.to determine fire history, whereas remote sensing compares historical views of vegetation from space to recent views to show how vegetation has changed over time. Fire history can also be determined using management procedures, which are organizational, and include Indian fire use or post-settlement management choices.
