Indian journal of scientific research
Manika Mann is a perennial water body and therefore, different hydrophytes and algal flora constitute a rich biodiversity. As the Mann is surrounded by the agricultural lands so the pond water is enriched with different nutrients that promote growth of different kinds of macrophytes and diverse algal flora. During seasonal survey, the epihydates, helophytes, hyperhydate, plankton, pleustophytes, rosulates, vittate of macrophytes were found. During rainy season the bed of the Mann is completely
... Mann is completely filled with rain water as well the runoff water from the surrounding. During this seasons only floating macrophytes, such as Eicchornia, Lemna, Ipomoea spp, were found on the surface. From Octobed to December, Trapa, Euryal ferox, Eicchornia, Pistia were noted on the surface, while in the water, few feet deep, Ceratopyllum, Vallisneria, Hydrilla etc. were noted. During this period near the bank, Colocasia, wild species of Poaceae, members of Cyperaceae were found. During summer the water depth is reduced and is present in the bed only. The marshy and moist marginal land was occupied by Sedge grass and members of Poaceae.
