Flowering calendar of a particular area will give the information of the period and duration…show more content… It is situated 38 km south of the capital city (Imphal) of Manipur State (Fig.1). Loktak Lake is almost oval-shaped and length and breadth calculating maximum during rainy season attains 26 km and 13 km respectively, with an elevation of 768.5 m above the mean sea level. It is a eutrophic natural fresh water lake and the biggest lake in the north eastern India. During lean season the lake is very shallow ranges from 0.5 to 1.5 m and total water spread reached about 490 km2 during rainy season [L.D.A., 1996]. From the isotopic data of the Loktak Lake sediments suggest that the lake is about 25, 000 years old i.e. the middle of the last glacial period [Mitra et al.,1986]. The origin and evolution of the lake may be ascribed to tectonic activity and neotectonism remarkably influenced by a long history of fluviolacustral process [Singh and Singh,…show more content… • To examine the availability of macrophytes in various seasons has a close relationship with the health status of human beings (Wild edible food plants, medicinal plants, precaution of allergenic pollen producing plants) and fodder for the wild animals like Sangai (Rucervus eldii eldii McClelland), an endangered deer species in this globe, and migratory and endemic birds as their food.
• If the dominant macrophytes are disturbed by human anthropogenic activities, the natural habitat of Sangai will be disturbed leading to extinction, and the only floating mat Phumdi aquatic environment will be no
