Analysis of Tree Rings and Fire Scars to Establish Fire History

Traditional counting of tree rings between fire scars to establish a fire history is examined for a better understanding of factors influencing fire scar formation and wound healing. The problem of dating fires which burn prior to or after the period of cambial activity is emphasized. A methodology for fire history studies based on fire scar and tree-ring analysis developed by Arno and Sneck (1977) is reviewed and elaborated upon. The importance of crossdating, height of sample cross sections, and problems associated with the extrapolation of data are discussed. Ongoing research involving the examination of the mineral concentration of tree rings and the presence of traumatic resin canals as markers of past fires is reviewed.This item is part of the Tree-Ring Research (formerly Tree-Ring Bulletin) archive.
