The mangrove ecosystem of Indian Sundarbans in the lower Gangetic delta region sustains a number of mangrove associate floral species whose ecosystem services have not been properly evaluated. We present here few ecosystem services of Porteresia coarctata and Ipomoea pes-caprae in the sphere of environment upgradation and alternative livelihood. Recent advancements in these two sectors have opened up a new horizon, which has high potential to improve the economic profile of the people living in this mangrove dominated lower Gangetic delta region.
