Characteristics of the habitat for Dianthus superbus L. var. longicalycinus (Maxim.) Williams on Senbonhama Seashore in Numazu

Abstract

We investigated the habitat characteristics of Dianthus superbus at Senbonhama seashore, Suruga Bay, Japan. The highest density of D. superbus was observed in the grassland of the high zone, whereas it was not found in the semi-stable zone of the seashore. The results of the belt-transect survey did not establish a correlation between population density of D. superbus and environmental conditions in each quadrat. The DCA and cluster analysis using the cover degree of plants appearance in each quadrat grouped D. superbus with Miscanthus sinensis. We considered that the semi-natural grassland, which is formed between the pine forest and the semi-stable zone, is the primary habitat of D. superbus.
