	%X The forest stand consisted of four layers. The species
composition between the third and the bottom layers was almost
similar, whereas it was almost exclusive between the top and the lower
three layers. The values of Shannon-s index H' and Pielou-s index
J ' tended to increase from the bottom layer upward, except for
H' -value of the top layer. The values of H' and J ' were 4.21 bit
and 0.73, respectively, for the total stand. High woody species
diversity of the forest depended on large trees in the upper layers,
which trend was different from a subtropical evergreen broadleaf
forest grown in silicate habitat in the northern part of Okinawa Island.
The spatial distribution of trees was overlapped between the third and
the bottom layers, whereas it was independent or slightly exclusive
between the top and the lower three layers. Mean tree weight of each
layer decreased from the top toward the bottom layer, whereas the
corresponding tree density increased from the top downward. This
relationship was analogous to the process of self-thinning plant
populations.
