YAEYAMA ISLANDS MARINE PLANT DATABASE

ISIGAKI ISLAND


Yaeyama islands comprising many islands with and without inhabitant took attraction when a project of building an air field on a coral reef widely spreading in front of Siraho district of Isigaki city. Fortunately, the project was stopped by protest of many domestic nature conservation movement groups.

After this case, WWF/Japan begun a series of funding for survey activities on coral reef and their marine organisms conservation of Ryukyu archipelago. In 1998, our group started a three-year survey project funded by WWF/Japan to make basic study on marine plant flora including seaweeds, spore-producing plants, and Spermatophytes, seed producing plants. This series of marine plant floral survey of Yaeyama islands was started in 1965 for Akatsuka's Bachelor's thesis and continued with some-year-intervals so far. Scientific names of species so far identified are presented in this English page and Japanese names are attached to Scientific names in Japanese page.
