Abstract
The awareness of natural environment has grown in Japan recently. With a view to respond to diversifying needs and to restore natural environment which has been damaged in the past, various initiatives incorporating environmental functions into port facilities have been examined.
Port and Development department of Kyushu Regional Development Bureau, Ministry of Land, Infrastructure, Transport and Tourism allowed us to carry out an experiment on a temporary storage mound for caissons in the waters of the Port of Hosojima, Miyazaki, Japan from March 2010 to September 2011.
This study researched the inhabiting situation of seaweed, small animals, and fish and shellfish by setting up a seashell facility on the vertical surface of a concrete caisson on the temporary storage mound for caissons in the sea. We have confirmed improvement effects in the habitat including enhancement in biodiversity.
