Historical, Observed, and Modeled Wildfire Severity in Montane Forests of the Colorado Front Range
Figure 5
Distribution of 232 sites with historical (pre-1920) evidence of low-severity and mixed-severity fires.
Sites with historical evidence of mixed-severity fires are differentiated with evidence of low- and moderate-severity fire (no evidence of high-severity fire; 108 sites) and low- to high-severity fire (106 sites). Areas mapped as historical low-severity fire only (27.8%) and mixed-severity fire (72.2%) are shown in green and orange, respectively. Three example graphs are also shown to illustrate the evidence (remnant trees, tree establishment and spreading fires) used to classify sites with evidence of low and mixed-severity fire effects at individual sites.
