Vegetation changes, such as shrub encroachment and forest expansion over grasslands, prairies andsavannas have been related to changes in climatic (mainly rainfall and temperature) and atmosphericconditions (CO2concentration). However, a longstanding question in ecology is how mosaics of forestsand open-canopy ecosystems could persist over millennia in sites where climatic conditions favor forests.Here we tested the influence of interactions between grass-tree competition, environmental hetero-geneity (topography), seed dispersal, initial density and spatial aggregation of vegetation patches anddisturbance behavior (fire) on the long-term coexistence of forests and grasslands in South Brazil. Forthis, we incorporated the adaptive dynamic global vegetation model (aDGVM) into a spatially explicitmodeling approach (2D-aDGVM). Our results showed that recurrent disturbance related to grasses such asfires plays a key role in maintaining the long-term coexistence of forests and grasslands, mainly throughfeedbacks between disturbance frequency and grass biomass. Topographic heterogeneity affected therate of forest expansion by adding spatio-temporal variability in vegetation-fire feedbacks. However, thespatial pattern and connectivity of fire-prone (grasslands) and fire-sensitive (forest) vegetation patcheswere more important to maintain the long-term coexistence of both alternative vegetation states thanthe initial proportion of forest and grasslands patches. The model is the first individual-based DGVM toconsider the combined effects of topography, seed dispersal and fire spread behavior in a spatially explicitapproach.
