It’s been a month since we celebrated mangrove’s day. In order to increase community awareness of the importance of mangroves, on 26th July 2021 Titian invite community to celebrating International Mangrove Day. In that day, we planting 35 Xylocarpus, sp at the sea side of the orchard (Muara Ulu Besar). Although Xylocarpus doesn’t dominate in the Mahakam Delta area, we still try to plant it to see its resilience.
Based on vegetal formation, the delta area can be divided into several zones namely pedada zone, bakau zone, transition zone, nypa zone, and nibung zone. The pedada zone is located closest to the delta front and is characterized by pedada (Sonneratia alba) and api-api (Avicennia sp.) with vegetal thickness about 100–150 m. The bakau (Rhizopora) zone is found mostly in the bank of tributary channels in the lower delta area and on an island like in Tunu and Selete islands. The transition zone is a mixed zone where many species of mangrove such as api-api (Avicennia sp.), pedada (Sonneratiacaseolaris), bakau (Rhizopora sp.), tancang (Bruguiera sp.), nyirih (Xylocarpus granatum), and nipah (Nypa fruticans) grow together.
