Our group have been working on ecological restoration of degraded mangrove patches outside the protected areas in Indian Sundarbans settlement regions in the shoreline mangroves lining the estuarine rivers since 2014 with financial assistance from Department of Biotechnology, Government of India and with all logistic supports from Forest Department, Govt. of West Bengal. Initially we attempted developing a model site-specific biorestoration technology for an approx. 3-ha degraded patch of mangroves on banks of Mridangabhanga-Barchara confluence at the village Ramganga, Patharpratima Block, South 24 Pgs, West Bengal. Our reference ecosystem was the co-located nearby pristine protected mangroves at Lothian, Prentice, Bhagabatpur, Diya, Dhonchi, Bonnie Camp, Kalash, Chulkathi islands, under the Sundarban Biosphere Reserve, India. At the present moment, in 2023, this small semi-restored patch has shown quite improvement, and now it is harbouring almost 30 species of mangroves and associate species including rare and threatened ones, associated fauna, and huge natural regeneration of mangrove seedlings in each season, proving the restoration of functionality of the ecosystem as a whole. Once barren, now this site is a biodiverse hub and have been included in the internal website of OECM India as a potential OECM site. This site-specific degraded mangrove ecological restoration technology developed by our group is presently expanded for another 30 sites comprising of about 60 ha of degraded mangroves outside the PA region in river shores of Sundarban villages in Patharpratima Block, with all financial supports from Department of Biotechnology, Government of India.
