Status of diversify of medicinal plants in floodplain basin of northern Bangladesh

Status of macrophyte diversity of floodplain basin, under Netrokona and Sunamgonj haor basin of Bangladesh was conducted and a total number of 30 species of aquatic weeds were identified from the surveyed area. These macrophytes provide medicinal importance of direct human benefit and shelter to the periphyton and other aquatic insects, and act as a source of feed to the fish. Due to increasing pressure of agriculture, aquaculture and global affect, important 01 species were extinct, 04 species were endangered, 05 species were vulnerable status, 09 species were in lower risk and 11 species were not threatened position from biodiversity view point. Initiation of new technology for growth of aquatic weeds in the floodplain through community based comanagement policy, would be helped to expand growth level in the survey area.
