Abstract

The importance of biological diversity has been world-widely recognized, because, depending on and linking up with each other in natural environment, many kinds of living things make up different ecological systems. Hiroshima Prefecture declares one project titled “Rings of life for the future! Hiroshima plan (Hiroshima Strategy of Biological Diversity)” and has started to carry it out. Besides this ordinance, the prefectural assembly decided on Hiroshima Principal Plan for Environment, regarding preservation of bio-diversity as a very important policy. As the result, “Red Data Book Hiroshima – Endangered Wild Plants and Animals in Hiroshima Prefecture” was published in 2011. The plants and animals mentioned here are the objects to be preserved urgently for keeping diversity. Osakikamijima is an isolated island and the plants on this island haven’t been researched in detail. This paper is a research report about the rare and endangered plants of Osakikamijima.
