| 内容記述 | Chrysanthemum wakasaense （Asteraceae） is a perennial herb, distributed over the Japan Sea side areas of Tottori, Hyogo, Kyoto and Fukui prefectures, as well as calcareous mountains in Shiga prefecture and adjacent areas. The species is treated as an endangered plant of Japan （Environmental Agency of Japan 2007） and of some prefectures, however, the rank and criteria of categories differ nationally and between the prefectures. In 2008, a follow-up survey after 30 years was conducted on the 59 coastal populations of C. wakasaense in the four prefectures in order to evaluate its threatened status. Among them, 14 populations （23.7%） had become extinct, another 14 populations （23.7%） exhibited size-reduction, 28 populations （47.5%） had maintained their original population sizes, and two populations （3.3%） showed exceptional size-enlargements. In the four prefectures, a marked difference was recognized in the conditions; extinction and reduction were predominant in Tottori, Kyoto, and Fukui Prefectures, while no extinction was found in Hyogo Prefecture. The main factors for extinction of the species were presumed to be natural succession and roadworks. Cultivated garden chrysanthemums, which can cause genetic pollution in wild chrysanthemums, were observed in 21 populations （47.7% of the present populations）, which were neighboring places with garden flowers and/or cemeteries or stone statues of Jizo with offerings of flowers. In actual fact, the natural hybrids between C. wakasaense and garden chrysanthemum were observed in 6 populations （13.6%）. Re-evaluations to the rank of C. wakasaense as an endangered plant of Japan and of related prefectures, and suggestions for conservation of the species were presented here. | |||||||
