Available from TreeSearch: http://www.treesearch.fs.fed.us/ Abstract: This site is part of a broader project to infer the climate drivers of regional fire years in the US northern Rockies, i.e., Idaho and Montana west of the Continental Divide. We needed a multicentury record of widespread fires across the region to meet the objectives of our broader study and therefore we targeted sites historically dominated or co-dominated by ponderosa pine that historically sustained frequent surface fires. Tree locations were determined using handheld global position system receivers. Injuries in the FHX file include both eroded scars (i.e., ones for which much or all of the overlapping, curled woundwood rings were destroyed by subsequent fires or rot) and abrupt changes in the width of annual rings that were synchronous with fire scars on other trees at this sites. We assigned ring-boundary scars to the preceeding calendar year at this site.

They are available in both PDF and PNG formats. The graphs consist of 2 parts, both of which show the X axis (time line) at the bottom with the earliest year of information on the left and the latest on the right. The Fire Index Plot is the topmost plot, and shows two variables: sample depth (the number of recording trees in each year) as a blue line along the left Y axis, compared with the percent trees scarred shown as gray bars along the right Y axis. Below, the Fire Chronology Plot consists of horizontal lines representing injuries by year on individual sampled trees. Symbols are overlain that denote the years containing the dendrochronologically-dated fire scars or injuries. The sample ID of each tree is displayed to the right of each line. The Composite Axis below represents the composite information from all individual series. The symbols used to represent the fire scars or injuries, and the filters used to determine the composite information, are shown in the legend. These graphs were created using the Fire History Analysis and Exploration System (FHAES). See http://frames.nbii.gov/fhaes/ for more information.
