The landscape of Karwar is intricate and complex, to say the least. River Kali meets the Arabian Sea, and together the waters caress the Western Ghats. At this estuary is an island – Devbagh. The shoreline around the island is bordered by mangrove forests, making the entire area a biodiversity hotspot, as innumerable species of flora and fauna are supported by these forests. The sandy beaches, the mudflats that are exposed at low tide, and the mangroves themselves are home to several species of crabs, which play a crucial role in the preservation of these environments.
