Matang mangrove forest, the biggest mangrove forest tract in Peninsular Malaysia, has an area of 400 Km2, which, together with the high primary productivity of mangrove forest ecosystem, means the carbon fixation capacity of Mantang mangrove forest is very huge. However, human activity and climate change have degraded its function of fixing carbon and biodiversity conservation to some extents. The spatial planning and management of Mangrove forest conservation zones is expected to help improve and maintain its role in mitigating and adapting to climate change.
