dc.description.abstractThe coastal areas in Northern and Eastern part of Srilanka became an eyesore on 8th November 2021 with unprecedented amount of macrophytes piled upon the beaches. A survey was carried out to identify and analyze the distribution of macrophytes accumulated along the coast. Morphometric analysis was performed based on shapes of leaves, leaf margins, vein structures, leaf and stalk textures and length of petiole to confirm the species. The leaves of the plants under the study were found as shiny, roughly round, ovoid or kidney-shaped, up to 15cm across in length with densely arranged longitudinal veins. Leaf stalks were bulbous and spongy. The petiole of the plant was about 50cm long often swollen and its base enclosed in a stipule. From the morphometric study, the plants accumulated was identified as water hyacinth(Eichhornia crassipes). Water hyacinth is one of the world’s most invasive aquatic plants that native to the Amazon basin, spread from South America to other parts of the world and is known to cause significant ecological and socio-economic effects. This plant was introduced as an ornamental plant into the state of West Bengal of India in the 18th century. Currently, India is severely infested by this weed. It is noteworthy that during the period of accumulation in Srilanka, the similar incident was also recorded in Kovalam Beach, India. Based on the meteorological data and the distribution of species, it was presumed that it had been followed by severe flood condition and also by high velocity water currents originated in the Bay of Bengal. As a follow up action, it is necessary to study the potential utilization of these accumulated plants in the future.en_US
