Mangrove Forest of Roswar Island, in the National Park of Cenderawasih Bay, the Province of West Papua

Abstract

Research on mangrove vegetation on Rowsar Island, in the area of the National Park of Cenderawasih Bay, This research was conducted from March to April 20223. West Papua Province conducted to identify and understand the condition of the mangrove forest. This research use quantitative methods by inventory with path plots. Based on the observations of mangrove vegetation on Roswar Island, 10 types of true mangroves identified, i.e Rhizopora mucronata, Rhizopora apiculata, Sonneratia alba, Xylocarpus granatum, Sonneratia caseolaris, Bruguiera gymnorrhiza, Avicennia marina, Avicennia rumphiana, Aegialitis annulata, dan Aegiceras floridum. The general mangroves found at every station are Rhizopora apiculata dan Rhizopora mucronata. Rhizopora apiculata grows in muddy, soft, deep, and waterlogged soil. Rhizopora apiculata does not like growing on harder substrates mixed with sand. The dominance rate can reach 90% of the vegetation growing in a location. Rhizopora mucronata grows in the same area as Rhizopora apiculata but more tolerant to hard substrates and sand. Mangrove forests on Roswar Island are still in good condition and extensive, the diversity of the mangrove plant species is relatively high and its natural regeneration is going well. The management of the mangrove forest areas requires coordination, integration, synchronization, and synergy across sectors, between many agencies and institutions.
