Table 1 Mean aboveground (a) and belowground (b) biomass (g m⁻²± SEM), litter (g m⁻²), and belowground to aboveground (b/a) biomass ratio of oaks, palmettos and other species across categories of TSF (yr). Here we calculated mean belowground to aboveground biomass ratios of palmettos and other species only for sites for which both the aboveground and belowground biomass were observed.
