Crossdated fire histories (1650-1900) from ponderosa pine-dominated forests of Idaho and western Montana. Gen. Tech. Rep. RMRS-GTR-214WWW. Fort Collins, CO: US Department of Agriculture, Forest Service, Rocky Mountain Research Station. 83 p. Available from TreeSearch: http://www.treesearch.fs.fed.us/ Abstract: These samples were collected by John Sloan and others on contract to the Salmon-Challis National Forest in 2001 and 2002. Samples were collected in clusters of 1 to 7 trees - sometimes the location of individual trees was recorded, sometimes only a single location for the tree cluster. Furthermore, each UTM zone is 500,000 meters wide along any meridian, therefore there are no easting coordinates greater than 500,000 meters in the UTM coordinate system. However, the easting coordinates for this site ranged from 730,548 to 746,440. We inferred that when these coordinates were recorded in the field, the global positioning system receiver was set to record in zone 11 whereas the site is actually in zone 12. Therefore, we corrected the UTM coordinates by subtracting 500,000 meters from the recorded easting. In 2003, the Salmon-Challis National Forest requested that Emily K. Heyerdahl crossdate these samples, who selected for crossdating a subset of the best preserved samples from 52 trees with the greatest number of fire scars. 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 generally assigned ring-boundary scars to the preceding calendar year at this site. However, for one fire, scars occurred in the earlywood of most trees but on the preceding ring boundary of another. We inferred that the scars in both positions were created by a single fire burning early in the growing season and therefore re-assigned the ring-boundary scar to the following calendar year, in other words, the same year as the earlywood scars (tree NFS48, original year: 1818 , re-assigned year: 1819). Comments: Collected by John Sloan north and south of Salmon, Idaho on contract to the Salmon-Challis National Forest.

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.
