In the grass area there were a few individuals of fire-resisting 

 trees, chiefly Antidesma ghaesembilla (binayuyu), Bauhinia 

 malabarica (alibangbang), and Acacia farnesiana (aroma). 

 Soon after fires were excluded from the region, a growth of 

 tree seedlings, herbaceous shrubs, and vines entered quickly. 

 The early stages of this process are accompanied by changes in 

 the composition of the grasses, as cogon and talahib are usually 

 replaced by species forming even taller stands, which, however, 

 are much less dense. The grass gradually dies as the trees 

 begin to shade it. In this manner large parts of the area have 

 passed from grasslands to second-growth forest since 1911. 

 The tree species which have come in are so numerous and the 

 composition of the forest so varied that it is difficult to tell which 

 are the most prominent species, but among them are Melochia
