Global Status of Mangrove Ecosystems: Commission on Ecology Papers Number 3

This report examines the ecological characteristics, distribution, uses, and management of mangrove ecosystems in tropical and subtropical coastal regions. It compiles available data on global mangrove extent, species composition, and associated biological communities, drawing on published studies, questionnaires, and mapping techniques to describe their geographic distribution and ecological diversity. The document explains key ecological processes such as nutrient cycling, sediment dynamics, and the export of organic matter that supports estuarine food webs and fisheries. It also analyses major causes of mangrove degradation, including freshwater diversion, mining, coastal development, and land conversion. The report further reviews governance arrangements, international cooperation needs, and management approaches intended to support sustainable use and long-term conservation of mangrove resources.
