Records of past fire occurrence from tree rings, charcoal found in lake sediments, and other proxies. Parameter keywords describe what was measured in this data set. Additional summary information can be found in the abstracts of papers listed in the data set citations. Additional information on the International Multiproxy Database (IMPD) data set procedures are also available. STUDY NOTES: This site was sampled as part of a project to reconstruct historical fire regimes in central Oregon. White fir (Abies concolor) and grand fir (Abies grandis) hybridize in the sampling area and are difficult to identify in the field so we did not attempt to distinguish between these two species, but report them as a combined category. Ring-boundary fire scars were assigned to the preceding calendar year. Several metadata files are provided with the FHX file. -999 in any file indicates no data. https://www1.ncdc.noaa.gov/pub/data/paleo/firehistory/firescar/northamerica/supplemental/usbee002_plot_data.csv provides information on the plots. https://www1.ncdc.noaa.gov/pub/data/paleo/firehistory/establishment/northamerica/supplemental/usbee002_recruitment.dat provides information on the trees from which we attempted to remove wood samples (at least 20 cm in diameter at breast height (1.4 m) from which it appeared we could obtain an intact wood sample). https://www1.ncdc.noaa.gov/pub/data/paleo/firehistory/firescar/northamerica/supplemental/usbee002_saplings.csv provides information on small trees that we did not attempt to remove wood samples from. These trees were tallied in each plot by species and diameter class (measured at breast height, 1.4 m) in 5.6-m radius plots. Diameter classes: 2.5 (0-5 cm), 7.5 (5-10 cm), 15 (10-20 cm). https://www1.ncdc.noaa.gov/pub/data/paleo/firehistory/firescar/northamerica/supplemental/usbee002_scarred_tree_info.csv provides information on fire-scarred trees, including ones we also sampled for recruitment date. https://www1.ncdc.noaa.gov/pub/data/paleo/firehistory/firescar/northamerica/supplemental/usbee002_undatable_trees.csv provides information on trees from which it did not appear that we could obtain intact wood samples.
