Abstract: Saving the life of the Angono River system is the ultimate vision of this research. Specifically, it analyses the vegetation along the riparian zones of the river’s headwater as important benchmark information for future environmental actions of government agencies. Transect walk and satellite imagery revealed that the land cover, based on Standard Land Cover Classification System of the Department of Environment and Natural Resources (DENR) of the Philippines, is a non-forest other land cultivated annual. It was also found out that the tree vegetation is already weak and in critical condition and the very few remaining tree species are threatened by the fact that the study site is privately owned by a realty developer and a mining company and occupied by informal settlers. Thus, rehabilitation, conservation, protection and other important research endeavors, within the whole length of the river system are deeply calling for an immediate and active priority and concern from its various private and public stakeholders.
