Abstract: On field sampling of different wetland pockets( six selected sampling sites) of Saharsa district falling under Kosi division, as many as 15 different species of chlorophyceae as members of blue green algal flora have been recorded that reflect the species richness of the group in this habitat. As regards the species abundance of these species, the individuals of the species have also been numerically counted from the algal samples in the net. The data has been statistically computed to investigate its relative abundance (RA %=Σn/N).
