Abstract
To examine the ecological characteristics of seagrasses growing naturally in Dokdo, shoot morphology and density of seagrasses in a study site each from Dongdo and Seodo, where seagrasses occurred, were investigated in September 2016. In the study sites, Phyllospadix japonicus Makino, a protected seagrass species, was found to be scattered, forming small clusters. P. japonicus shoots from the study sites in Dongdo and Seodo were morphologically similar. The mean leaf width was 2.0 mm at both study sites in Dongdo and Seodo. Numbers of leaves per shoot was 4.8 and 4.7, and the leaf lengths were 42.5 cm and 41.9 cm, in Dongdo and Seodo, respectively. The shoot densities were $3,500{\pm}334.2shoots\;m^{-2}$ and $2,275{\pm}415.1shoots\;m^{-2}$, in Dongdo and Seodo, respectively, with no significant difference. Shoot density and morphological chacteristics of P. japonicus in Dokdo were similar to those on the eastern coast of the Korean peninsula.
