Ecologists and silviculturelists have spent much time trying to understand and explain
the species patterns and associations in tropical rain forests. An assoeiation analysis by
computer of data where no distinction is made between treea of lhe upper canopyr and those
smaile" trees of the middle canopy (which are underlined) is given in Tabb l. Tabb I shows

Species underlined TEH, BURO etc. seldom grow larger than I80 cm
girth, and so do not influence North New Georgia analysis.
Examples of botanical names: ALAJ = Alanjium javanicum; BURO = Burekella obovata;
CALK = Calophyllum kajewskii; CALV = Calophyllum vitiense
GONM = Gonystylus macroPhYllus
