No trees produce on the average more than one log 5 meters in length. The most numerous tree was api-api (Avicennia), and the next was bakauan (Rhizophora spp.). The third most numerous species was busain (Bruguiera sexangula). The wood of api-api {Avicennia) is of compar- atively little value, but is extensively used as firewood. That of the other species is very valuable. Forester Medina has also made valuation surveys of other stands in Samar. The results are given in Tables VII to XI. In all of these tables, bakauan (Rhizophora spp.) is the most numerous tree. The second most numerous is api-api (Avi- cennia). This species, however, is very much less numerous than bakauan (Rhizophora spp.) and is represented by a much smaller volume. In Table VIII, langarai (Bruguiera parviflora) ranks next to bakauan (Rhizophora spp.) and api-api (Avi- cennia) third. The average volume per hectare in the different areas varies from to cubic meters. These tables represent swamps which have been used to some extent for the collection of firewood.
