Root Biomass Estimation in Natural and Planted Mangrove

Belowground root biomass plays an essential role in the mangrove ecosystem as potential carbon storage, nutrient gain, or sediment accumulation yet is still overlooked. Therefore, estimation of necessary. The objective was to determine and compare belowground at natural planted ecosystem. We also measured forest structure aboveground biomass. This study conducted four stations Pramuka Island, Pari Rambut Island (2 stations), Seribu Islands, Jakarta. first island represented mangroves, whereas latter two stems. Rhizophora stylosa dominant species three except for 2 that dominated by Ceriops Tagal. Stand densities were 2730±5 stems ha-1, 1733±5 1311±2 1300±2 ha-1 1 2. highest pile density counted 1612±8 lowest (780±5 ha-1). estimated follows 109.13±11.91 Mg 89.45±19.53 2, 68.41±17.12 1, 14.05±5.74 Island. (3.63±0.82 ha-1) other mangroves (6.56±0.47 (7.17±0.81 ha-1), similar (49.23±6.77 contribution ranges from 6-24% total trees, fine roots (< mm) occurred 28-74% entire results confirm high pool importance maintaining a part rehabilitation.
