Ch. Nivanonee and B. Manihar Sharma

Abstract

lkop Lake is a fresh water, saucer-shaped natural lake, situated in the South-Eastern part of Imphal at a distance of about 40 km.This eutrophic lake has an area of 13.5 sq. km and lies at an intersection of 93° 52' to 94°05' E longitude and 24°31 to 24°40' N latitude and it is situated at an altitude, of 772 m above the mean sea level. Phytosociological study was carried out for twentynine macrophytic species. Quantitative or objective analysis comprises Frequency, Density,Abundance,Abundance/ Frequency, ratio Relative Frequency, Relative Density, Relative Abundance and computation of Importance Value Index from the relative values of Frequency, Density and Abundance which gives the overall picture of ecological importance with respect to the community structure.
