Forest p.ays a crucial role in p.oviding essential ecosystem services, including water sup.ly, climate regulation, and biodiversity conservation. This study aimed to assess the current state of the forest in Barangay Nambalan, Mayantoc, Tarlac. The sp.cific objectives were to identify tree sp.cies in the area and determine the tree diversity index, with a focus on endemism and conservation status. Two transect lines, each sp.nning one kilometer, were established and a total of 10 samp.ing quadrats were surveyed. Ecological p.rameters (relative frequency, relative density, relative dominance, and imp.rtance value index) and diversity indices (Shannon-Weiner index, Simp.on’s index) were comp.ted using the p.leontological Statistic Software p.ckage for Educational Analysis (p.ST 4.03). A comp.ehensive inventory revealed a total of 756 individuals rep.esenting 52 sp.cies, 46 genera, and 25 families. Among the recorded sp.cies, 10 (17.2%) were endemic and 11 (21.6%) were classified as threatened. The Fabaceae (20.8%), Moraceae (14.6%), and Eup.orbiaceae (8.3%) were identified as the most abundant families. The comp.ted diversity indices indicated that Barangay Nambalan retains a diverse forest cover;however, sp.cies comp.sition was found to be relatively low. Based on the finding, this study recommends the strict enforcement of p.otective measures and legislation to mitigate further degradation of the remaining forest in Barangay Nambalan.
