This study aimed to identify the herb and shrub species in the forest ecosystem of Kalikasan Park, Albay, Philippines. A fifty- meter transect line was established in the three sampling sites, with large 25-square-meter plots surveyed for species. A total of 20 species from 11 families were recorded, consisting of 14 herb species from nine (9) families and six (6) shrub species from four (4) families. Results indicated low diversity and medium species richness in the herb species, while the shrub species exhibited moderate diversity and richness, with species dominance suggesting ecological imbalance. Notably, seven (7) species were classified as “Least Concern” (LC), while half of the species sampled had “Unavailable Data” (UD), and some were categorized as “Widespread” (W). Interestingly, the sampled herb and shrub species possessed significant medicinal properties, including anti-inflammatory, antibacterial, and antioxidant applications. It is recommended to implement conservation strategies, conduct continuous species monitoring, and establish reforestation programs. Furthermore, promoting sustainable use of medicinal plants through community engagement and raising public awareness of biodiversity helps ensure long-term ecosystem conservation.
