The functioning, biogeochemical cycles (e.g., carbon and water), and the stability of grassland ecosystems are significantly affected by the conversion. To best manage and use those grassland ecosystems, it is imperative to examine how the shrub‐encroached grasslands can be Correspondence to: restored to native grassland ecosystems.

In the fenced plots, aboveground biomass increased for grass species and decreased for semishrub species.
