This book presents the significant values of the mangrove ecosystem, which include biotic and abiotic components, ecological protection, ethnobotanical uses, ecological indicators, and, differing from other books, environmental state heavy metal monitoring. Despite the widely acknowledged functional importance of mangrove forests, rapid degradation of mangrove forest resources has continued. In addition to stabilizing coastline zones, mangroves have the potential to clean up organic and inorganic contaminants, naturally. Local people have used mangrove resources for generations, to become a reflection of their culture, customs, and beliefs. This book may benefit people from different fields, including ecologists, landscape architects, researchers, students, etc., to understand in-depth mangrove identification, characteristics, and functional and aesthetical values. This book is purposely written to encourage people to conserve and preserve mangrove forests as a valuable natural heritage.
