Abstract

Ecological study has been conducted in the forest area of Natuna Island to reveal the structure and composition of
tree species. In the 10 plots of 20 x 40 m each, there were 141 species of trees, with a density of 504 trees / ha and
12.35 m2/ha of basal area, which was distributed in three forest types. Myrtaceae was the most common family,
followed by Euphorbiaceae and Dipterocarpaceae. On the other hand Arthrophyllum javanicum recorded as the
most common species together with Syzygium aemum and Ilex pleiobrachiata. The existence of each of the common species
varies in each forest type that shows there was a correlation between the condition of the habitat and the presence of
species.
