淡路由良，竹野の藻場モニタングサイト

摘要

As a part of the Monitoring Site 1000 Project, the algal bed monitoring sites `Awaji-Yura' and `Takeno' were set up for representing Seto Inland Sea and the Sea of Japan coast respectively. Awaji-Yura site is located at the mouth of Osaka Bay facing to Kitan Strait, and its algal bed community is character-ized by dense population of Ecklonia cava and Sargassum ringgoldianum ssp. coreanum. The observa-tion data of this site is useful for detecting the long-term changes of the site itself, but also important for evaluating the restoration activities of the coastal environments within Osaka Bay. Takeno site is located in Takeno Marine Park at the mouth of Ooura Bay, and the algal bed is characterized by the mixed population of diverse Sargassum species such as S. confusum, S. fulvellum, S. micracanthum, S. nigrifolium, S. patens, S. pilulife rum and S. siliquastrum, and Ecklonia kurome.
