Kalpita Bhatta and Hemant Kumar Patra

Abstract

The present study is a review on the assessment of macrophyte as bioindicators. As macrophytes are good in responding to the different water quality parameters therefore they are chosen as an indicator. A total of fifteen species of macrophytes with their occurrence in different physcio chemical characteristics of water such as pH, electrical conductivity were noted down after reviewing scientific papers dealing with the bio indicator. Submerged aquatic vegetation like Ceratophyllum demesrum is found in oligotrophic environmental condition whereas floating species such as Ludwigia stolonifera occurs in mesotrophic condition. Eichhornia crassipes occurs in the eutrophic conditions of lake.
