Abstract/ Executive Summary:

This paper deals with the distribution and the physical and biological environment of the mangroves of Bangladesh.It also discusses the importance and management of mangroves of Bangladesh. The mangroves of Bangladesh are significant globally because of their size, geological settings, biological diversity and natural resource and livelihood support potentiality. Among these mangroves, the Sundarbans on the south western coastal Bangladesh covers an area of 5700 km2 on the southern fringe of the Bengal Delta and represents one of the largest single tract mangrove forest of the world. This area represents physiographically an immature delta, geologically most recent and tectonically most active region of the world. Because of the favorable physical environment, biologically these mangrove ecosystems are one of the richest in the world. It represents about 50% of all major and minor mangroves in old-world (Indo-Pacific) and 41% of all mangroves in the world. The presence of Bengal Tiger among the terrestrial fauna qualifies the Sundarbans as one of the famous in the world. The importance of the Sundarbans among the mangroves in Bangladesh lies in the fact that it earns 41% of the total revenue, and produces 45% of the total timber and fuel wood in Bangladesh. These forests also provide habitat of 45% mammals, 42% birds, 46% reptiles, and 36%amphibians of the country. However, recently top-dying disease broke out affecting 17% of the sundri trees. The protective role of the mangroves from coastal natural hazards are well recognized in Bangladesh. Approximately600,000 people maintain their livelihood directly or indirectly from this forest. The management of mangroves in Bangladesh has a long history of 125 years. However, the mangroves are still degrading, and the reasons has been identified as the very large population living along the coastline, poverty, inadequacy of knowledge and lack of responsiveness of the Forest Department to social issues.

Achievement/Findings:

Approximately600,000 people maintain their livelihood directly or indirectly from this forest. The management of mangroves in Bangladesh has a long history of 125 years. However, the mangroves are still degrading, and the reasons has been identified as the very large population living along the coastline, poverty, inadequacy of knowledge and lack of responsiveness of the Forest Department to social issues
