Spatial modeling of forest-savanna bistability: Impacts of fire dynamics and timescale separation
This study uses a spatial Markov jump process model to simulate forest-grassland systems affected by fire dynamics. The model integrates seed dispersal, fire spread, and non-linear flammability to bridge slow vegetation models with fast fire dynamics. It demonstrates that these systems exhibit forest-savanna bistability, meaning both states (forest and savanna) can stably coexist under different conditions.
