Abstract: Pasir Ris Mangrove is left naturally to regenerate for 30 years after being affected by reclamation in 1978 and 1989. The rehabilitation works of the mangrove to sustain high number of individual mangrove species was to weed B. cylindrica seedlings and saplings that were growing in abundance. Trenching was also carried out to improve inundation of the mangrove area away from the river. The objective of the paper is finding out the natural regeneration of mangrove species in Pasir Ris Mangrove after being affected by reclamation 30 years ago and recent subjection to weeding and trenching. Additionally, this paper was set to find out whether if the density of existing plants, B. cylindrica could affect the growth of two mangrove species, B. gymnorrhiza and R. mucronata. The paper found that Pasir Ris Mangrove is thriving with at least 10 different types of mangrove species in an area of 0.05 ha. This is about 25% of mangrove species found in Singapore. The density of the existing plants in the mangrove has different effect on the experimented two mangrove species. R. mucornata responded positively with 80-100% survival rate and 13 cm growth within optimum plant density of 6- 10 plants. While B. gymnorrhiza seedlings survived better within area with more than optimum number of existing plants (more than 12 number of existing plants) but has high mortality rate of 75% that has the density of plant of more than 36 seedlings / m2. From this study, it showed that different type of mangrove species benefited different density of plants and initial improvement of inundation by trenching and increasing of canopy gap could further boost the number of individual mangrove species.
