The study looked at how planting different tree and shrub species in a degraded dry valley in Yunnan Province affected the vegetation and soil seed bank. Planting Leucaena glauca trees reduced biodiversity and changed the soil seed composition, while planting Coriaria sinica shrubs increased biodiversity and allowed native grass species to persist. The soil seed density increased with Leucaena glauca but decreased with Coriaria sinica. Both the rehabilitated and naturally regenerated ecosystems had some similar native species, but the changes in vegetation and soil seed bank varied between the two methods.
