Mapping of land cover on Pulau Tujuh and Pulau Layang-Layang, Kelantan delta mangrove

Abstract

Remote Sensing and GIS are a commonly used tools in coastal zone management, forestry and land use planning. This study was contributed to monitor the dominant species in replanted mangroves at Pulau Layang-layang and Pulau Tujuh, Kelantan Delta to estimate the boundaries and produce updated land cover map of Kelantan Delta mangrove. Based on the results, Rhizophora apiculata and Rhizophora mucronata were the dominant species for both islands with 80% accuracy. From Quickbird image and DGPS data comparison from boundaries of two islands, it was showed that accumulation had occurred, along shoreline with 7 ha increase for a Pulau Layang-layang and 6.04 ha for Pulau Tujuh. Significant of this study are to develop the management for replanted mangrove and gave new information to government and NGO about the change of mangrove ecosystem at Kelantan Delta.
