Recently, although civic groups working for Satoyama preservation are becoming more numerous, it will be difficult for such groups to continue operating for an extended period, meaning each individual involved in the activity must have their own motivation to work continuously. The purpose of this study was to investigate the changes of vegetation based on Satoyama preservation activities by civic groups, and assess the changes in vegetation affecting the awareness of the participants. In this study we examined the Satoyama forests of the suburban Hino city area in west Tokyo, and the civic group which preserved there. 36 quadrats were subject to flora survey, and we investigated the existing vegetation. Based on this research, we classified the plots according to the frequency and mode of management. Consequently, volunteer activities led to changes in the Satoyama vegetation. In particular, rare species appeared in areas which had been trimmed by hand based on personal judgment. Subsequently, we carried out a questionnaire survey and investigative discussion involving the members of the civic group. We found that the changes of vegetation, especially in terms of appearance and the flowering rare species generated through their activity, brought them pleasure and fulfillment. Consequently vegetation changes sparked by Satoyama preservation work would leave participants satisfied and motivate them to continue engaging in such activities.
