Abstract: The study was conducted to collect, identify and assess the weed biodiversity of Tanguar haor in a different season. It was done for 9 months from December’ 2015 to August’ 2016 in three seasons named as pre monsoon, monsoon and winter. A total of 26 species of aquatic weeds under 20 families were identified from the hoar areas. Among 3 common groups of aquatic weeds, 11 species of emergent, 12 species of floating 3 species of submerged were collected. Various aquatic weeds were found in different seasons i.e. Ecchornia crassipes, Pistia straties, Nymphoides indicum were found in the summer season, Nymphaea pubescens, Ipomoea aquatic, Enhydra fluctuans, Ludwigia adscendens, Azolla pinnata were found in winter and Ipomea fistulosa, Hidrilla verticulata, Najas minor were found in the year round. The season-based composition of weeds also observed where the highest number of composition was found in summer following by monsoon and winter. As the temperature is a factor for the growth of plants the temperature record was also studied, it was found highest in September and lowest in January. Therefore, as there was no previous study on particularly aquatic weeds this study will reveal some important information for the future study. Various recommendations and measures have been suggested to improve the biodiversity of aquatic weeds in Tanguar hoar area at Taherpur upazilla under Sunamgonj district.
