Fire Ecology

Table 1 Surface and canopy fuel properties of dry mixed conifer (DMC) and moist mixed conifer (MMC) states. CC canopy cover (%), CH canopy height (m), CBH canopy base height (m), CBD crown bulk density (kg m⁻³). Stand structural classes include post-fire bare ground (PFBG), stand initiation (SI), stem exclusion open canopy (SEOC), stem exclusion closed canopy (SECC), understory re-initiation (UR), young forest multi-story (YFMS), old forest multi-story (OFMS), and old forest single story (OFSS). Surface fuel models are fire behavior fuel models (FBFMs) of Scott and Burgan (2005). An alternative fuel model assignment (ALT FBFM) is used to represent generally cooler and moister fuels in cold forests
