Figure 6: Model states predicted from steady states at the end of simulations on a square lattice for all relevant combinations of MAR and distance to agriculture.

Figure 6

(a) State diagram as function of distance from agriculture (δ) and MAR (P) (example with average seasonality and soil conditions). Between savanna and forest, the colour scale represents the proportion of the lattice that is occupied by adult trees. The solid black line shows where the Maxwell point lies, that is, where this proportion settles to a stationary value that is not 0 or 100%. The dotted line shows the Maxwell point for high seasonality (MSI=0.86, 95% percentile) and the dashed line for low seasonality (MSI=0.12, 5% percentile). (b) Classification of the study area using P, M, δ and π. (c–f) Example simulations: (c) initial condition, (d–f) final states with δ and P values at the points indicated in a.
