Figure 6

A conceptual model of annual cumulative burn area as an interaction between ignition source (lightning or cultural) and general fire weather pattern (“moderate” or “dry” year) based upon the fire regime of an eastern slope area of the Montane Cordilleran ecozone (White 1985, Wierzchowski et al. 2002, Van Wagner et al. 2006). The model assumes that the previous year was a “wet” year with no area burned that would influence the current year’s burning pattern.
