We introduce a procedure to predict the vegetation shift using traditional phytosociological survey (cover data). The cover value is generally obtained for each layer of the layered plant community, but usually maximum cover value over the layers used for the vegetation classification and recognition (C-max procedure). As an ameliorate procedure, we propose the procedure of every coverage of all layers used to evaluate vegetation shift (C-all procedure). The C-all procedure enables us to embrace the information on vertical gradient of species distribution in the surveyed communities. In the case of our observations and analyses, tree species with smaller (or no) cover in the upper layer but greater cover in the lower layer can be dominant in the upper layer in the future, resulting in vegetation shift (changes in dominant species of the community). Every general community analysis (cluster analysis, INSPAN, and TWINSPAN) followed by C-all procedure supports such prediction for some types of Japanese forests. In the forests, changes in species composition have been conventionally predicted by measuring the trunk diameter and height of trees. Our proposal suggests that traditional phytosociological survey is also convenient for studying forest succession and regeneration.

“…For example, restoration assessments employing reference forests involve the comparison of vegetation indicators (canopy structure and species diversity) between restoration and reference forests [16]. Oyake et al (2019) employed a comparative analysis of the dominant species composition between the initially degraded area and the near-reference forest [17], carried out 33 years postrestoration, to assess the success of the restoration process. Furthermore, O 'Connell et al (2022) verified successful restoration by comparing and evaluating the vegetation networks of one restored mangrove forest and reference forest [18].…”

The reference forest serves as a model for forest ecosystem restoration and can be employed to assess the vegetation of the Restored Forest, thereby confirming the success of restoration. When evaluating restoration, employing multireference forests is advantageous for discerning gradual changes in Restored Forests. However, in previous studies, their utilization has been limited to comparisons with individual ecosystems. Therefore, this study investigates the status of Restored Forests in previously damaged areas and their resemblance to reference forests across four forest types, namely Climax Forest (CF), Secondary Forest (SF), Restored Forest (RF), and Planted Forest (PF). Reference forests, serving as model targets for restoration, include CF and SF, while RF and PF represent the restoration forests. Six target sites within two temperate deciduous forests (Quercus acutissima and Quercus variabilis) were selected, and a comparative analysis of species diversity, dominance, and evenness was conducted. This study revealed that the dominant species in the top canopy of restoration forests mirrored those in reference forests, with Q. variabilis and Q. acutissima being prevalent. A similarity index of over 60% and a high correlation of 0.987 were observed in the top canopy layer between the reference and restored ecosystems (CF-RF/SF-PF). These findings enhance our understanding of the current status of Restored Forests and advocate for the utilization of multiple reference forests for successful restoration efforts.
