Abstract


This research was conducted in Lirang Village, North Lembeh District, Bitung City by using quadrant and sampling methods. The study was conducted in 5 quadrants, namely the bottom (quadrant 1), the middle (quadrant 2), the top (quadrant 3), the left (quadrant 4) and the right (quadrant 5). Based on the calculation results, the highest species density and relative density were found in quadrant 3 with values of 0.09 and 87.10, respectively, with the species R. Mucronata. Likewise, in the same quadrant, the highest species frequency value was 1.00 with R. Mucronata and S. Alba species, while the relative frequency value was 75.00 with R. Mucronata. The highest species closure value was 15.09, which was owned by R. mucronata in quadrant 1, while the relative species closure value of 89.44 was owned by the same species in quadrant 3. The highest important value index of 251.53 was owned by R. mucronata is in quadrant 3.
