A STUDY ON FILAMENTOUS ALGAE IN KUTTANADU RICE AGROECOSYSTEM

Smitha Sebastian

Abstract :

 Kuttanadu agroecosystem is a complex mosaic of fragmented agricultural landscape which has a concave relief and slopes towards northwest and reaches below sea level towards west where it joins Vembanadu Lake– a Ramsar site. The landscape composition, structure, management and the regional context of Kuttanadu are unique and significant, as the region is a larger mosaic of fragmented landscape patches and varied ecosystems such as coastal backwaters, rivers, vast stretches of paddy fields, marshes, ponds, garden lands, edges and corridors. Algal population in this landscape was screened and observed 32 species of blue–green algae and 5 species of green algae with much difference in diversity and occurrence across the landscape. Algal diversities are natural occurrences, and may occur with stability depending on vegetation type, nutrient level, soil properties, humidity and climatic conditions of particular habitat.  The uniqueness of certain varieties in relation with soil regions, seasons and growth stages are also unveiled. Immediate measures to conserve algal genetic resources in the unique ecologically fragile and Globally Important Agricultural Heritage System – Kuttanadu – are recommended.
