Table 1 Mean values for surface fuel load (SFL), live canopy base height (CBH), and canopy bulk density (CBD) by fuel class cluster (FCC) and the corresponding minimum rate of spread (ROS) for crowning and sustained propagation of a crown fire
Fuel class cluster | n | Mean SFL (kg m−2) | Mean CBH (m) | Mean CBD (kg m−3) | Min. ROS for crowning (m min−1) | Min. ROS for sustained propagation of crown fire (m min−1) |
