Leucanthemella linearis (Matsum.) Tzvelev is an endangered species of a perennial herb that grows in wetlands of East Asia, including Japan. Its habitats are deteriorating nationwide in Japan, and it currently exists in only six prefectures: Ibaraki, Shizuoka, Gifu, Aichi, Okayama, and Hiroshima. In recent years, the remaining natural habitat for this species in Fukutomi Town (Higashihiroshima City, Hiroshima Prefecture) has rapidly deteriorated, mainly due to feeding damage caused by sika deer (Cervus nippon).
In this study, we report the results of field surveys and conservation activities conducted collaboratively by the university, a local junior high school, and local residents, with the aim of restoring the species’ habitat. Based on the results of these activities, we make recommendations for future conservation measures.
