The area trimmed included the vertical projection of the 30 * 30 m plot, utilizing
the following methods: All non-palm trees P15 cm diameter at
1.3 m height (d.b.h.) within the 30 * 30 m area had their branches
that were less than 10 cm diameter removed. For non-palm trees
between 10 and 15 cm d.b.h., each tree was trimmed at 3 m
height. For palms P3 m tall (at the highest part of the leaf above
ground), fronds were trimmed at the connection with the main
stem and the apical meristem was preserved
