Abstract:

This study investigated the tree community composition and conservation status within the riparian zone of Abbig Falls, a secondary lowland moist evergreen forest in Brgy. Ifugao Village, Diffun, Quirino, Philippines. Thirty-three species representing 18 genera and belonging to 13 families were identified, with Moraceae and Dipterocarpaceae being the most abundant. The presence of unidentified species underscores the need for further exploration. Ecological indices indicated moderate tree diversity and a balanced community. The Shannon Diversity Index (H') ranged from 2.5 to 2.99, reflecting moderate diversity, while Simpson's Diversity Index (1-D) indicated a relatively even species distribution. Importance Value (IV) analysis identified Pometia pinnata J.R.Forst. & G.Forst. and Celtis luzonica Warb. are the dominant species while recognizing the contribution of all species to overall richness. Notably, the critically endangered Pterocarpus indicus Willd. forma indicus highlights the importance of conservation efforts. The study recommends prioritizing threatened species for conservation, conducting further research to identify unknown species and assess their ecological roles, implementing sustainable management practices for valuable trees, and fostering collaboration with local communities for conservation awareness. Understanding the composition and conservation status of the riparian zone's trees is crucial for ensuring its long-term health and the ecological services it provides.
