5 CONCLUSION
The present findings showed that the presence of shrubs inhibited the
restoration rate and suggested that shrub-encroached grasslands is
another stable state in this region. If we want to restore the diversity
and composition of grassland community and maintain its function, it can
not be achieved only fencing, especially in the high shrub cover area ofC. microphylla . It may require some human interference practices
that inhibit C mircophylla growth (Xiong et al., 2004; Alados et
al., 2019) and incorporates biotic perspectives into the framework of
restoration (Koyama et al., 2015; Pierce et al., 2019).
