Fig. A1.2. Bifurcation of simple fire model with respect to fire frequency. When fires are frequent, there are two stable states, and the resilience of the longleaf pine (LL) state is large. As fire frequency declines, the resilience of the longleaf pine state decreases and that of the hardwood (HW) state increases. At fire frequencies of more than 7 yr/fire, then hardwood is the only stable state. The hardwood growth rate in this figure is 0.075.
