From: Fire regimes of the Southern Appalachians may radically shift under climate change
Landscape proportions of the functional groups represented in each fire return interval (FRI: years simulated/fires that occurred) in our model of fire regime and vegetation change in the Southern Appalachians. Each bar represents the mean percent of total live biomass of each functional group across all locations that experience that FRI across the landscape in all simulations under all climate models. Functional groups are defined in Table S.1. In this study, we used the LANDIS-II model to simulate the Southern Appalachians, USA, under four CMIP5 climate scenarios representing increased drought trend, increased drought variability, their combination, and a scenario with neither increase. These simulations were compared to the historical climate and each other to understand changes in fire patterns and landscape-scale changes in species composition and biomass
