* Data for miscellaneous trees less than 40 centimeters in diameter are not available. 



the main overmature stand is entirely removed in accordance 

 vi^ith a management plan based on a diameter limit, we have 

 left not a healthy, young, fast-growing stand, but a scattered 

 stand of weak, slender poles, incapable of producing seed and 

 often incapable of recovering from the suppression under which 

 they have developed. 



The undergrowth is much less dense than is usually the case 

 in Philippine forests, due to the well-developed and extremely 

 dense canopy and to the fact that this forest occurs on level 

 or gently rolling land. Various kinds of erect palms occur scat- 

 tered in all parts of the forest, as do rattans and other vines.
