Inventory of tree-level vegetation in the Bohulo camp tourism area

Abstract

This study aimed to inventory tree-level vegetation in the Bohulo Camp tourism area, located in Dulamayo Village, Gorontalo Regency. A field survey method was employed, involving direct observation and recording of tree species within the study site. Species identification was conducted based on morphological characteristics, followed by ecological index analysis. The vegetation structure was assessed using the Shannon–Wiener diversity index (H'), species evenness (E), and species richness (R) to describe community composition and stability. The results recorded 29 tree species comprising a total of 202 individual trees. Dominant species included Myristica sp., Swietenia sp., Chisocheton ceramicus, and Ailanthus sp. The Shannon–Wiener diversity index (H' = 3.2209) indicates a high level of species diversity. The evenness value (E = 0.9565) suggests a relatively uniform distribution of individuals among species, while the species richness index (R = 5.2748) reflects considerable variation in species composition. Overall, the findings indicate that the Bohulo Camp tourism area possesses a stable tree vegetation structure and strong ecological potential to support sustainable nature-based tourism management.
