F49	49–50	Pinus massoniana, Lithocarpus glaber, Loropetalum chinensis	135–160	107684.94 ± 5452.03^a
F70	~ 70	Lithocarpus glaber, Choerospondias axillaris, Cyclobalanopsis glauca	85–99	114287.05 ± 13889.07^a
UF	Old-growth forest	Lithocarpus glaber, Cleyera japonica, Cyclobalanopsis glauca	200–260	120695.16 ± 11552.85^a

Different letters indicate significant differences between the four forests at the P < 0.05 level. Values represent means ± SE (n = 6). The F14, F49, F70, and UF refer to the respective restoration stage, the same below. Abbreviations: AGB above-ground biomass
