Mangrove vegetation mapping and distribution using high spectral resolution image of quickbird at ten selected islands in Kelantan Delta

Abstract

Mangroves are among the most productive coastal ecosystem and they are developing well in sheltered estuaries and deltas. It is very importance to protect and monitor to make sure that they will always in good conditions. Kelantan Delta is new mangroves. A study was done to obtain the information of the mangroves status and distribution in Kelantan Delta. This study classifies mangroves vegetation at ten selected islands of Kelantan Delta using QuickBird imagery. QuickBird imagery was used because it is the latest of Very High Resolution (VHR) satellite sensor with 0.61m resolution. The study was done at the September to October 2006. Mapping of the mangroves vegetation at the western part of Kelantan Delta was done using unsupervised and supervised classification. To clarify the ground trothing data, simple inventory procedure was done at four of the islands which were Pulau Che Minah, Pulau Tengkorak, Pulau Bedal and Pulau Terendak. Eleven types of mangrove forests: Avicennia, Nypa .fructicans, mix mangroves, Sonneratia-Avicennia, Avicennia-Nypa Acanthus-Nypa, Sonneratia-Nypa, Sonneratia­ Acanthus, Hibiscus-Nypa, Acanthus-Acrosticum and Rhizophora spp. replanting area were classified. Mangrove vegetations were distributed widely in all of the islands at the western part of Kelantan Delta.
