In Table III busain (Bruguiera conjugata) is represented by 
more individuals and about twice the volume of any other 
species, and contains more than half the total volume. Langarai 
(Bruguiera parviflora) is the next most numerous species and 
after busain is represented by a larger volume than any other 
species. These two species of Bruguiera compose 83.5 per cent 
of the total volume of the stand. Bakauan (Rhizophora spp.) 
contains 13.9 per cent of the total stand. The other species are 
present in small quantities. The greatest volume is found within 
the 20- and 25-centimeter diameter classes, these classes com- 
posing 58 per cent of the total volume.
