Outline of Final Research Achievements

Vegetation survey was conducted in natural and secondary lucidophyllous forests on Bonin Islands. The results showed that species composition differed between the natural and secondary forests. An artificial lucidophyllous forest dominated by planted Cinnamomum camphora is located in the urban area of Nishinomiya City, Hyogo Prefecture. 37 late-successional species were found across the forest. This species number was much lower than that calculated using two formulae for species-area relationship reported in a study of natural lucidophyllous forests. In addition, species composition was very different between the artificial and natural lucidophyllous forests, with many late-successional species not seen in the artificial forest. Species composition was compared among Cryptomeria japonica plantations, secondary lucidophyllous forests, and natural lucidophyllous forests on Yakushima Island. The results showed that species composition differed among the three forest types.
