Biodiversity of Tanguar Haor : a Ramsar site of Bangladesh : volume I : wildlife

Wetlands are amongst the Earth's most productive ecosystems. In Bangladesh these are of great importance because of the extensive food webs and rich biodiversity they support. In the past, wetlands have been undervalued. However, in recent times, awareness increases of the fact that natural wetlands provide many services toward mankind through various functions, products e.g., fish, fuelwood, timber, rice, and attributes i.e., biodiversity, aesthetic beauty, cultural heritage and archaeology.
