Abstract:

This study conducted a floristic inventory within the Central Bicol State University of Agriculture Pasacao Campus to identify plant species, assess their abundance, and determine their conservation status. The study aimed to provide baseline data for biodiversity conservation, ecological education, and sustainable campus management using a descriptive quantitative design through systematic sampling across five study sites. A total of 261 individual plants representing 54 species under 32 families were recorded. The dominant families identified were Asteraceae, Fabaceae, Poaceae, and Commelinaceae, which are known for their adaptability to tropical and disturbed environments. Among the sampling sites, Site 5 (Production Area) had the highest species richness with 69 species, while Site 3 (Shrub Area) recorded the lowest with 40 species. Herbs comprised the largest proportion of flora at 48%, followed by shrubs (21%), trees (18%), grasses (9%), and ornamentals (4%). This indicates that the campus vegetation is in an early to mid-successional stage dominated by pioneer species. Conservation status assessment based on DENR DAO 2017 11 and IUCN (2024) showed that 72% of species were classified as Least Concern, 15% as Introduced, 8% as Vulnerable, 3% as Endangered, and 2% as Near Threatened. Notable species included Vitex parviflora (Molave) and Swietenia macrophylla (Mahogany). The findings show that CBSUA Pasacao Campus supports moderately diverse flora and serves as a valuable foundation for biodiversity monitoring, conservation planning, and environmental education. Further studies are recommended to strengthen conservation strategies for native and threatened species.
