Wind-speed thresholds for predicted fire types (km/hr), where canopy fuel moisture varies.

Wind speeds (km/hr) at which four fire types are expected for the four MPB stages: Green, Red, Grey and Old-MPB under three moisture scenarios: extreme drought (XD), very dry (VD) and moderately dry (D) moisture scenarios, where available canopy fuel moisture reflects the proportion of red and green needles in each stage as in Table 1C. See Table 2 for description of fire types.
