Mangroves in India

• India contributes to nearly half of the total mangrove cover in South Asia.

• According to the Forest Survey report 2021 released in January, mangroves cover in the country is 4,992 square km, which is 0.15 per cent of the country's total geographical area. Since 2019, the cover has risen by only 17 sq km.

• West Bengal has the highest percentage of mangrove cover in India, mainly because it has Sundarbans, the largest mangrove forest in the world. It is followed by Gujarat and Andaman, and Nicobar islands.

• Other states that have mangrove cover are Maharashtra, Odisha, Andhra Pradesh, Tamil Nadu, Goa and Kerala.
