Fire history dendrochronology study, super old growth data, central western Cascades, Oregon, 2002

The primary objectives of this study were to assay where super old-growth (SOG) persists on the landscape, what factors enabled it to survive for more than 550 years, and to develop a predictive model for the occurrence of SOG. To meet these objectives, data were synthesized from prior fire history work done in the central western Cascades of Oregon (Morrison and Swanson unpublished; Teensma 1987; Morrison and Swanson 1990; Weisberg 1998). The study involved the following steps: (1) the collection of primary data and maps from each study, (2) the creation of a master database, and (3) analysis of the synthesized data.
