Diviseema Mangroves

Diviseema Mangroves are an estuarine mangrove ecosystem located in the Diviseema island region near Avanigadda in Krishna District, Andhra Pradesh. Formed at the Krishna River delta where the river meets the Bay of Bengal, the mangroves are notable for their biodiversity, coastal protection role, and bird habitat. The area is valued for nature tourism, boating and birdwatching near Hamsaladeevi and Nagayalanka.

Visitors can expect a low-lying estuarine landscape with dense mangrove vegetation, tidal creeks and mudflats at the Krishna River delta. The area is accessed via roads to Avanigadda and Nagayalanka with local boat services to explore creeks. Visitors can see mangrove species, migratory and resident birds, fishing hamlets and the river-sea confluence environment. Facilities are basic and visits are typically daylight, nature-focused and dependent on tides and local boat availability.

Diviseema island is historically noted for the 1977 Andhra Pradesh cyclone that severely impacted the delta region. Mangroves in the Krishna delta have since been recognized for their role as a natural bio-shield against cyclones and tidal surges, with subsequent conservation and regeneration efforts to restore coastal protection.

The mangroves support traditional fishing and aquaculture communities of Diviseema. The surrounding delta region is culturally associated with river-sea confluence pilgrimage at Hamsaladeevi (Sagara Sangamam) and local agrarian and fishing livelihoods.
