A study on macrophyte diversity in Dipai Beel, Kokrajhar district, BTAD, Assam

Aquatic macrophyte diversity and its role in understanding the wetland ecosystem dynamics, have tremendous significance. Macrophytes may be used as ecological indicators for assessing and predicting environmental changes in water. The perennial species are continuously exposed and able to integrate environmental conditions over a large period. Dipal Beel is a natural fresh water body in Kokrajhar district. The species composition status of aquatic macrophytes in Diplai Beel is studied and recorded in 2014–15. After collection, the species are categorized on the basis of ecological habits into seven types such as i. Free floating-6 species, ii. Submerged anchored-4 species, iii. Submerged suspended-2 species, iv. Rooted with floating leaves-7 species, v. Rooted with floating shoot-1 species, vi. Submerged anchored-4 species, vii. Emergents-13 species. The study reveals enumeration, effect of abundance and rareness of macrophytes in Diplai Beel ecosystem.
