A Conservation Biology of Aster kantoensis Growing along the Tama River

Abstract

Perspectives for the conservation biology of Aster kantoensis growing in the floodplain of the Tama River are presented. In this paper, we report on the studies mainly with regards to its life-history and spatio-temporal distribution pattern. Historical analys is demonstrated that the area of the community containing A. kantoensis has been greatly reduced. Local extinct and regeneration histories suggest the importance of the availability of seed source for maintenance and recruitment of the populations. The conservation plans on wild populations of A. kantoensis are proposed.
