PRESENT STATUS OF AQUATIC MACROPHYTES OF FOUR FRESH WATER ECOSYSTEMS OF ELLANDHAKUTA AND ITS SURROUDING VILLAGES, KARIM NAGAR DISTRICT, TELANGANA. INDIA

ABSTRACT

Present study was conducted on four fresh water ecosystems to analyses,the importance of fresh ecosystems biological components, species diversity, alienspecies, aquatic macrophytes distribution in four  villages around study area was studied during 2012-2014. One hundred and ten different species of were recorded in 41 families in these 24 from Dicotyledons, 14, Monocots, two from Pteridophyta, one from Algae total Genera 84. Poaceae was the most dominant families with 14 species followed by Cyperaceae (10species), Asteraceae(9), Euphorbhiaceae (7), and Twenty five families were represented by one species each. But unfortunately, such very resourceful fresh water ecosystems are gradually degrading due to various natural and manmade activities like, development of commercial fisheries, excessive growth of invasive aquatic weeds mainly Eichhornia crassipes (Mart.) S.L., Leersia hexandra SW and Hymenachne acutigluma (Steud) Gill which are suppressing the growth of other associated species,causing of loss of native biota. The migratory birds are Actitis hypoleucos, Ardea purpurea, Plegadis chihi, Mycteria leucocephala.

Key Words: Macrophytes, Invasive weeds, Native biota, Emergent anchored weeds
