Site description The open mudflats of Trombay and Sewri are located along the Arabian Sea. An area c. 10 km long and 3 km wide, is dominated by mangroves all along the coast. The area is prohibited for the general public. The jetty of Mumbai Port Trust (MbPT), Bhabha Atomic Research Centre (BARC), and Tata Electrical are located along the area. There are refineries of Oil and Natural Gas Commission (ONGC), Bharat Petroleum Corporation Limited (BPCL) and Hindustan Petroleum Corporation Limited (HPCL). Despite the high degree of pollution, the area is a winter refuge for thousands of migratory birds from as far as the Arctic circle. They include sandpipers, plovers, gulls and terns. The area also supports a large congregation of flamingos, which are local migrants probably from Gujarat. Raptors also use the area as a stopover and a few of them winter here, such as the Eurasian Marsh Harrier Circus aeruginosus and the Greater Spotted Eagle Aquila clanga. The area is dominated by mangrove vegetation and supports a diverse flora. Fifty-three species of vascular plants have been recorded. Of these 10 species are mangroves and 13 are mangroveassociated species. Avicennia marina is a dominant plant species in the area, while Rhizophora mucronata and Excoecaria agallocha also occur.
