Macrophytes and Macroinvertebrates are the key components of aquatic system. Investigation was carried out to ascertain their association in a floodplain wetland. for two consecutive years.. Samples were collected fortnightly with hand picking, drag netting & sampler .These were washed, sieved , sorted and identified . Altogether twenty seven different species of aquatic mcrophytes and 26 species of macro-invertebrates representing largely three major groups- Annelida, Inscta and Mollusca, were recorded from the wetland. Almost 80% of zoobenthic forms (20 species) were found with submerged plants , 12 with free floating , 13 with rooted free floaign and only 4 species were recorded with emergent plants. The Results obtained is suggestive of influence of macrophytes on macroinvertebrate abundance .
