Background and Objective: Grasses are diverse in taxonomic diversity and exhibit wide range of tolerance against the environmental factors qualifying as a pioneer species of an ecological community. In wetland ecosystems, grasses are redundant elements with huge functional roles in purification of the soil quality and acting as organizers of the macro-invertebrate communities. Keeping in view the role of the grasses in the wetland ecosystems, the present study was aimed at recording the diversity of the grasses in wetlands of Birbhum, West Bengal, India. The purpose of the study was to document the taxonomic diversity of the grass species, its functional role and prospective use in the restoration of the ecosystems. Materials and Methods: The investigation was carried out during 2012-2016 covering 65 wetland areas of Birbhum. Plant specimens were collected and processed for preservation and identification following standard taxonomic methods. Results: The present taxonomic study revealed the occurrence of 28 species belonging to 18 genera of the family Poaceae in 65 wetlands of Birbhum district. Most of the species occur in the moist fringe areas of wetlands. The distribution of Poaceae in wetland scenario of the district indicates a later stage (sedge-meadow) of ecological succession (hydrosere) which proceeds from the periphery towards centre. Conclusion: It was apparent that the grasses (Poaceae) contribute considerably to the wetland producers and play crucial role in developing the seral stages of the ecosystem development in the study area. Assuming equally diverse functional role of the grasses in the concerned wetlands, the present document may be used to gain preliminary information about the grasses and biological significance in the wetlands of the concerned regions of India.
