Table 2 Total plant biomass C storage (the sum of tree, shrub and herbs biomass C storage), forest floors C storage, and soil organic C (SOC) storage at the different depths as well as ecosystem C storage (the sum of total plant biomass C, forest floors C, and SOC storage) in the 6th year after treatments. P and F values were from the results of one-way ANOVA. EU, NS, UB, B stand for Eucalyptus plantation, naturally recovered shrubland, and the treatments of unburning and burning, respectively
