Abstract– : On rigorous sampling of hydrophytes of four selected chaurs being the part of wet land habitat of Supaul District in Kosi Division (North Bihar), 23 different varieties of hydrophytes have been sampled and taxonomically identified for their scientific names along with the local common names. As a part of random sampling in the chaurs by net sweep method the abundance of each hydrophyte per unit quadrate was numerically counted on the spot and the data procured were statistically analysed for evaluating the collective diversity value of all the hydrophytes in different chaurs as well as single chaur by applying Shannon-Weiner species diversity index. Statistically significant result has been procured which is helpful in predicting the ecological and environmental health of the hydrophytes as the dwellers and chaurs as the shelter.
