 Remote sensing has been found to be effective for monitoring the status and changes of mangrove areas in Iskandar, Malaysia. Two widely used classification techniques were tested, and the maximum likelihood classification, MLC, technique proved to provide better results than the support vector machine, SVM. Overall, the area of mangroves decreased by 33% from 1989 to 2014, with a rate of 241 hectares per year due to urban expansion. To prevent further loss of mangroves, gazetted protected areas should be established and tourism activities should be introduced in these areas.
