Table 3 Comparison between severity quartiles and classified severity between 1984 and 2005. The classified severity (from van Wagtendonk and Lutz 2007) uses a fire atlas originally developed by Thode (Miller and Thode 2007, Thode et al. 2011). The present study used the MTBS fire atlas. The comparison is for the burned areas of fires covered by both studies.
