This floodplain ecoregion lies along the confluence of the Ganges and Brahmaputra. The climate is tropical and highly seasonal. The southwest monsoon brings more than 3,500 mm of rainfall between June and September. Frequent cyclones in the Bay of Bengal cause widespread floods. The vegetation is semi-deciduous. The trees that form the canopy includes several deciduous trees that lose their leaves during the dry season, but the lower, understory trees stay evergreen. Tall red silk cotton trees Bombax ceiba dominate the open forests. But mature forests are dominated by sal Shorea robusta trees. Riparian forests are characterized by Acacia catechu and Dalbergia sissoo, with scattered silk cotton trees.
